enabled by default. After the update, you will see the number of crash free sessions and crash free users on the Releases page in Sentry. To disable automatic session tracking, use `sentry_options_set_auto_session_tracking`. +- Breakpad support for Windows. This allows you to use `sentry-native` even on Windows XP! ([#278](https://github.com/getsentry/sentry-native/pull/278)) +- Add an in-process backend for Windows. As opposed to Breakpad, stack traces are generated on the device and sent to Sentry for symbolication. ([#287](https://github.com/getsentry/sentry-native/pull/287)) +- Support for the Crashpad backend was fixed and enabled for Linux. ([#320](https://github.com/getsentry/sentry-native/pull/320)) +- A new `SENTRY_BREAKPAD_SYSTEM` CMake option was added to link to the system-installed breakpad client instead of building it as part of sentry. + +**Fixes**: + +- Reworked thread synchronization code and logic in `sentry_shutdown`, avoiding an abort in case of an unclean shutdown.

+ +# Official Sentry SDK for C/C++ + +The _Sentry Native SDK_ is an error and crash reporting client for native +applications, optimized for C and C++. Sentry allows to add tags, breadcrumbs +and arbitrary custom context to enrich error reports. Supports Sentry _20.6.0_ +and later. + +**Note**: This SDK is being actively developed and still in Beta. We recommend +to check for updates regularly to benefit from latest features and bug fixes. +Please see [Known Limitations](#known-limitations). + +## Resources + +- [Discord](https://discord.gg/ez5KZN7) server for project discussions. +- Follow [@getsentry](https://twitter.com/getsentry) on Twitter for updates + +## Table of Contents + +- [Downloads](#downloads) + - [What is Inside](#what-is-inside) +- [Platform and Feature Support](#platform-and-feature-support) +- [Building and Installation](#building-and-installation) + - [Compile-Time Options](#compile-time-options) + - [Build Targets](#build-targets) +- [Runtime Configuration](#runtime-configuration) +- [Known Limitations](#known-limitations) +- [Development](#development) + +## Downloads + +The SDK can be downloaded from the [Releases] page, which also lists the +changelog of every version. + +[releases]: https://github.com/getsentry/sentry-native/releases + +### What is Inside + +The SDK bundle contains the following folders: + +- `external`: These are external projects which are consumed via + `git submodules`. +- `include`: Contains the Sentry header file. Set the include path to this + directory or copy the header file to your source tree so that it is available + during the build. +- `src`: Sources of the Sentry SDK required for building. + +## Platform and Feature Support + +The SDK currently supports and is tested on the following OS/Compiler variations: + +- 64bit Linux with GCC 9 +- 64bit Linux with clang 9 +- 32bit Linux with GCC 7 (cross compiled from 64bit host) +- 32bit Windows with MSVC 2019 +- 64bit Windows with MSVC 2022 +- macOS Catalina with most recent Compiler toolchain +- Android API29 built by NDK21 toolchain +- Android API16 built by NDK19 toolchain + +Additionally, the SDK should support the following platforms, although they are +not automatically tested, so breakage may occur: + +- Windows Versions lower than Windows 10 / Windows Server 2016 +- Windows builds with the MSYS2 + MinGW + Clang toolchain + +The SDK supports different features on the target platform: + +- **HTTP Transport** is currently only supported on Windows and platforms that + have the `curl` library available. On other platforms, library users need to + implement their own transport, based on the `function transport` API. +- **Crashpad Backend** is currently only supported on Linux, Windows and macOS. +- **Client-side stackwalking** is currently only supported on Linux, Windows, and macOS. + +## Building and Installation + +The SDK is developed and shipped as a [CMake] project. +CMake will pick an appropriate compiler and buildsystem toolchain automatically +per platform, and can also be configured for cross-compilation. +System-wide installation of the resulting sentry library is also possible via +CMake. + +Building the Crashpad Backend requires a `C++14` compatible compiler. + +**Build example**: + +```sh +# configure the cmake build into the `build` directory, with crashpad (on macOS) +$ cmake -B build -DCMAKE_BUILD_TYPE=RelWithDebInfo +# build the project +$ cmake --build build --parallel +# install the resulting artifacts into a specific prefix (use the correct config on windows) +$ cmake --install build --prefix install --config RelWithDebInfo +# which will result in the following (on macOS): +$ exa --tree install +install +├── bin +│ └── crashpad_handler +├── include +│ └── sentry.h +└── lib + ├── cmake + │ └── sentry + ├── libsentry.dylib + └── libsentry.dylib.dSYM +``` + +Please refer to the CMake Manual for more details. + +**Android**: + +The CMake project can also be configured to correctly work with the Android NDK, +see the dedicated [CMake Guide] for details on how to integrate it with gradle +or use it on the command line. + +[cmake]: https://cmake.org/cmake/help/latest/ +[cmake guide]: https://developer.android.com/ndk/guides/cmake + +**MinGW**: + +64-bits is the only platform supported for now. +LLVM + Clang are mandatory here : they are required to generate .pdb files, used by Crashpad for the report generation. + +For your application to generate the appropriate .pdb output, you need to activate CodeView file format generation on your application target. To do so, update your own CMakeLists.txt with something like `target_compile_options(${yourApplicationTarget} PRIVATE -gcodeview)`. + +If you use a MSYS2 environement to compile with MinGW, make sure to : + +- Create an environement variable `MINGW_ROOT` (ex : `C:/msys64/mingw64`) +- Run from `mingw64.exe` : `pacman -S --needed - < ./toolchains/msys2-mingw64-pkglist.txt` +- Build as : + +```sh +# Configure with Ninja as generator and use the MSYS2 toolchain file +$ cmake -GNinja -Bbuild -H. -DCMAKE_TOOLCHAIN_FILE=toolchains/msys2.cmake +# build with Ninja +$ ninja -C build +``` + +**MacOS**: + +Building universal binaries/libraries is possible out of the box when using the +[`CMAKE_OSX_ARCHITECTURES`](https://cmake.org/cmake/help/latest/variable/CMAKE_OSX_ARCHITECTURES.html) define, both with the `Xcode` generator as well +as the default generator: + +```sh +# using xcode generator: +$ cmake -B xcodebuild -GXcode -DCMAKE_OSX_ARCHITECTURES="arm64;x86_64" +$ xcodebuild build -project xcodebuild/Sentry-Native.xcodeproj +$ lipo -info xcodebuild/Debug/libsentry.dylib +Architectures in the fat file: xcodebuild/Debug/libsentry.dylib are: x86_64 arm64 + +# using default generator: +$ cmake -B defaultbuild -DCMAKE_OSX_ARCHITECTURES="arm64;x86_64" +$ cmake --build defaultbuild --parallel +$ lipo -info defaultbuild/libsentry.dylib +Architectures in the fat file: defaultbuild/libsentry.dylib are: x86_64 arm64 +``` + +Make sure that MacOSX SDK 11 or later is used. It is possible that this requires +manually overriding the `SDKROOT`: + +```sh +$ export SDKROOT=$(xcrun --sdk macosx --show-sdk-path) +``` + +### Compile-Time Options + +The following options can be set when running the cmake generator, for example +using `cmake -D BUILD_SHARED_LIBS=OFF ..`. + +- `SENTRY_BUILD_SHARED_LIBS` (Default: ON): + By default, `sentry` is built as a shared library. Setting this option to + `OFF` will build `sentry` as a static library instead. + If sentry is used as a subdirectory of another project, the value `BUILD_SHARED_LIBS` will be inherited by default. + + When using `sentry` as a static library, make sure to `#define SENTRY_BUILD_STATIC 1` before including the sentry header. + +- `SENTRY_PIC` (Default: ON): + By default, `sentry` is built as a position independent library. + +- `SENTRY_EXPORT_SYMBOLS` (Default: ON): + By default, `sentry` exposes all symbols in the dynamic symbol table. You might want to disable it in case the program intends to `dlopen` third-party shared libraries and avoid symbol collisions. + +- `SENTRY_BUILD_RUNTIMESTATIC` (Default: OFF): + Enables linking with the static MSVC runtime. Has no effect if the compiler is not MSVC. + +- `SENTRY_LINK_PTHREAD` (Default: ON): + Links platform threads library like `pthread` on unix targets. + +- `SENTRY_BUILD_FORCE32` (Default: OFF): + Forces cross-compilation from 64-bit host to 32-bit target. Only has an effect on Linux. + +- `CMAKE_SYSTEM_VERSION` (Default: depending on Windows SDK version): + Sets up a minimal version of Windows where sentry-native can be guaranteed to run. + Possible values: + + - `5.1` (Windows XP) + - `5.2` (Windows XP 64-bit / Server 2003 / Server 2003 R2) + - `6.0` (Windows Vista / Server 2008) + - `6.1` (Windows 7 / Server 2008 R2) + - `6.2` (Windows 8.0 / Server 2012) + - `6.3` (Windows 8.1 / Server 2012 R2) + - `10` (Windows 10 / Server 2016 / Server 2019) + + For Windows versions below than `6.0` it is also necessary to use XP toolchain + in case of MSVC compiler (pass `-T v141_xp` to CMake command line). + +- `SENTRY_TRANSPORT` (Default: depending on platform): + Sentry can use different http libraries to send reports to the server. + + - **curl**: This uses the `curl` library for HTTP handling. This requires + that the development version of the package is available. + - **winhttp**: This uses the `winhttp` system library, is only supported on + Windows and is the default there. + - **none**: Do not build any http transport. This should be used if users + want to handle uploads themselves + +- `SENTRY_BACKEND` (Default: depending on platform): + Sentry can use different backends depending on platform. + + - **crashpad**: This uses the out-of-process crashpad handler. It is currently + only supported on Desktop OSs, and used as the default on Windows and macOS. + - **breakpad**: This uses the in-process breakpad handler. It is currently + only supported on Desktop OSs, and used as the default on Linux. + - **inproc**: A small in-process handler which is supported on all platforms, + and is used as default on Android. + - **none**: This builds `sentry-native` without a backend, so it does not handle + crashes at all. It is primarily used for tests. + +- `SENTRY_INTEGRATION_QT` (Default: OFF): + Builds the Qt integration, which turns Qt log messages into breadcrumbs. + +- `SENTRY_BREAKPAD_SYSTEM` / `SENTRY_CRASHPAD_SYSTEM` (Default: OFF): + This instructs the build system to use system-installed breakpad or crashpad + libraries instead of using the in-tree version. This is generally not recommended + for crashpad, as sentry uses a patched version that has attachment support. + This is being worked on upstream as well, and a future version might work with + an unmodified crashpad version as well. + +| Feature | Windows | macOS | Linux | Android | iOS | +| ---------- | ------- | ----- | ----- | ------- | --- | +| Transports | | | | | | +| - curl | | ☑ | ☑ | (✓) | | +| - winhttp | ☑ | | | | | +| - none | ✓ | ✓ | ✓ | ☑ | ☑ | +| | | | | | | +| Backends | | | | | | +| - inproc | ✓ | ✓ | ✓ | ☑ | | +| - crashpad | ☑ | ☑ | ✓ | | | +| - breakpad | ✓ | ✓ | ☑ | (✓) | (✓) | +| - none | ✓ | ✓ | ✓ | ✓ | | + +Legend: + +- ☑ default +- ✓ supported +- unsupported + +- `SENTRY_FOLDER` (Default: not defined): + Sets the sentry-native projects folder name for generators which support project hierarchy (like Microsoft Visual Studio). + To use this feature you need to enable hierarchy via [`USE_FOLDERS` property](https://cmake.org/cmake/help/latest/prop_gbl/USE_FOLDERS.html) + +- `CRASHPAD_ENABLE_STACKTRACE` (Default: OFF): + This enables client-side stackwalking when using the crashpad backend. Stack unwinding will happen on the client's machine + and the result will be submitted to Sentry attached to the generated minidump. + Note that this feature is still experimental. + +- `SENTRY_SDK_NAME` (Default: sentry.native or sentry.native.android): + Sets the SDK name that should be included in the reported events. If you're overriding this, make sure to also define + the same value using `target_compile_definitions()` on your own targets that include `sentry.h`. + +### Build Targets + +- `sentry`: This is the main library and the only default build target. +- `crashpad_handler`: When configured with the `crashpad` backend, this is + the out of process crash handler, which will need to be installed along with + the projects executable. +- `sentry_test_unit`: These are the main unit-tests, which are conveniently built + also by the toplevel makefile. +- `sentry_example`: This is a small example program highlighting the API, which + can be controlled via command-line parameters, and is also used for + integration tests. + +## Runtime Configuration + +A minimal working example looks like this. For a more elaborate example see the [example.c](examples/example.c) file which is also used to run sentries integration tests. + +```c +sentry_options_t *options = sentry_options_new(); +sentry_options_set_dsn(options, "https://YOUR_KEY@oORG_ID.ingest.sentry.io/PROJECT_ID"); +sentry_init(options); + +// your application code … + +sentry_close(); +``` + +Other important configuration options include: + +- `sentry_options_set_database_path`: Sentry needs to persist some cache data across application restarts, especially for proper handling of release health sessions. It is recommended to set an explicit absolute path corresponding to the applications cache directory (equivalent to `AppData/Local` on Windows, and `XDG_CACHE_HOME` on Linux). Sentry should be given its own directory which is not shared with other application data, as the SDK will enumerate and possibly delete files in that directory. An example might be `$XDG_CACHE_HOME/your-app/sentry`. + When not set explicitly, sentry will create and use the `.sentry-native` directory inside of the current working directory. +- `sentry_options_set_handler_path`: When using the crashpad backend, sentry will look for a `crashpad_handler` executable in the same directory as the running executable. It is recommended to set this as an explicit absolute path based on the applications install location. +- `sentry_options_set_release`: Some features in sentry, including release health, need to have a release version set. This corresponds to the application’s version and needs to be set explicitly. See [Releases](https://docs.sentry.io/product/releases/) for more information. + +## Known Limitations + +- The crashpad backend on macOS currently has no support for notifying the crashing + process, and can thus not properly terminate sessions or call the registered + `before_send` hook. It will also lose any events that have been queued for + sending at time of crash. + +## Development + +Please see the [contribution guide](./CONTRIBUTING.md). diff --git

This file is offered as-is, +without warranty of any kind. + +Basic Installation +================== + + Briefly, the shell commands `./configure; make; make install' should +configure, build, and install this package. The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. Some packages provide this +`INSTALL' file but do not implement all of the features documented +below. The lack of an optional feature in a given package is not +necessarily a bug. More recommendations for GNU packages can be found +in *note Makefile Conventions: (standards)Makefile Conventions. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + + The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package, generally using the just-built uninstalled binaries. + + 4. Type `make install' to install the programs and any data files and + documentation. When installing into a prefix owned by root, it is + recommended that the package be configured and built as a regular + user, and only the `make install' phase executed with root + privileges. + + 5. Optionally, type `make installcheck' to repeat any self-tests, but + this time using the binaries in their final installed location. + This target does not install anything. Running this target as a + regular user, particularly if the prior `make install' required + root privileges, verifies that the installation completed + correctly. + + 6. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 7. Often, you can also type `make uninstall' to remove the installed + files again. In practice, not all packages have tested that + uninstallation works correctly, even though it is required by the + GNU Coding Standards. + + 8. Some packages, particularly those that use Automake, provide `make + distcheck', which can by used by developers to test that all other + targets like `make install' and `make uninstall' work correctly. + This target is generally not run by end users. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. This +is known as a "VPATH" build. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple `-arch' options to the +compiler but only a single `-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the `lipo' tool if you have problems. + +Installation Names +================== + + By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX', where PREFIX must be an +absolute file name. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. In general, the +default for these options is expressed in terms of `${prefix}', so that +specifying just `--prefix' will affect all of the other directory +specifications that were not explicitly provided. + + The most portable way to affect installation locations is to pass the +correct locations to `configure'; however, many packages provide one or +both of the following shortcuts of passing variable assignments to the +`make install' command line to change installation locations without +having to reconfigure or recompile. + + The first method involves providing an override variable for each +affected directory. For example, `make install +prefix=/alternate/directory' will choose an alternate location for all +directory configuration variables that were expressed in terms of +`${prefix}'. Any directories that were specified during `configure', +but not in terms of `${prefix}', must each be overridden at install +time for the entire installation to be relocated. The approach of +makefile variable overrides for each directory variable is required by +the GNU Coding Standards, and ideally causes no recompilation. +However, some platforms have known limitations with the semantics of +shared libraries that end up requiring recompilation when using this +method, particularly noticeable in packages that use GNU Libtool. + + The second method involves providing the `DESTDIR' variable. For +example, `make install DESTDIR=/alternate/directory' will prepend +`/alternate/directory' before all installation names. The approach of +`DESTDIR' overrides is not required by the GNU Coding Standards, and +does not work on platforms that have drive letters. On the other hand, +it does better at avoiding recompilation issues, and works well even +when some directory options were not specified in terms of `${prefix}' +at `configure' time. + +Optional Features +================= + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + + Some packages offer the ability to configure how verbose the +execution of `make' will be. For these packages, running `./configure +--enable-silent-rules' sets the default to minimal output, which can be +overridden with `make V=1'; while running `./configure +--disable-silent-rules' sets the default to verbose, which can be +overridden with `make V=0'. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU +CC is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + HP-UX `make' updates targets which have the same time stamps as +their prerequisites, which makes it generally unusable when shipped +generated files such as `configure' are involved. Use GNU `make' +instead. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its `' header file. The option `-nodtk' can be used as +a workaround. If GNU CC is not installed, it is therefore recommended +to try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + + On Solaris, don't put `/usr/ucb' early in your `PATH'. This +directory contains several dysfunctional programs; working variants of +these programs are available in `/usr/bin'. So, if you need `/usr/ucb' +in your `PATH', put it _after_ `/usr/bin'. + + On Haiku, software installed for all users goes in `/boot/common', +not `/usr/local'. It is recommended to use the following options: + + ./configure --prefix=/boot/common + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS + KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf limitation. Until the limitation is lifted, you can use +this workaround: + + CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of all of the options to `configure', and exit. + +`--help=short' +`--help=recursive' + Print a summary of the options unique to this package's + `configure', and exit. The `short' variant lists options used + only in the top level, while the `recursive' variant lists options + also present in any nested packages. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--prefix=DIR' + Use DIR as the installation prefix. *note Installation Names:: + for more details, including other options available for fine-tuning + the installation locations. + +`--no-create' +`-n' + Run the configure checks, but stop before creating any output + files. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. diff --git a/shared/sentry/external/breakpad/LICENSE b/shared/sentry/external/breakpad/LICENSE new file mode 100644 index 000000000..a840b2647 --- /dev/null +++ b/shared/sentry/external/breakpad/LICENSE @@ -0,0 +1,132 @@ +Copyright (c) 2006, Google Inc. +All rights reserved. + +Redistribution and use in source and binary forms, with or without +modification, are permitted provided that the following conditions are +met: + + * Redistributions of source code must retain the above copyright +notice, this list of conditions and the following disclaimer. + * Redistributions in binary form must reproduce the above +copyright notice, this list of conditions and the following disclaimer +in the documentation and/or other materials provided with the +distribution. + * Neither the name of Google Inc. nor the names of its +contributors may be used to endorse or promote products derived from +this software without specific prior written permission. + +THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +"AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +A PARTICULAR PURPOSE ARE DISCLAIMED.

Building with ndk-build: +----------------------------- + +If you're using the ndk-build build system, you can follow +these simple steps: + + 1/ Include android/google_breakpad/Android.mk from your own + project's Android.mk + + This can be done either directly, or using ndk-build's + import-module feature. + + 2/ Link the library to one of your modules by using: + + LOCAL_STATIC_LIBRARIES += breakpad_client + +NOTE: The client library requires a C++ STL implementation, + which you can select with APP_STL in your Application.mk + + It has been tested succesfully with both STLport and GNU libstdc++ + + +I.2. Building with a standalone Android toolchain: +-------------------------------------------------- + +All you need to do is configure your build with the right 'host' +value, and disable the processor and tools, as in: + + $GOOGLE_BREAKPAD_PATH/configure --host=arm-linux-androideabi \ + --disable-processor \ + --disable-tools + make -j4 + +The library will be under src/client/linux/libbreakpad_client.a + +You can also use 'make check' to run the test suite on a connected +Android device. This requires the Android 'adb' tool to be in your +path. + +II. Using the client library in Android: +======================================== + +The usage instructions are very similar to the Linux ones that are +found at https://chromium.googlesource.com/breakpad/breakpad/+/master/docs/linux_starter_guide.md + +1/ You need to include "client/linux/handler/exception_handler.h" from a C++ + source file. + +2/ If you're not using ndk-build, you also need to: + + - add the following to your compiler include search paths: + $GOOGLE_BREAKPAD_PATH/src + $GOOGLE_BREAKPAD_PATH/src/common/android/include + + - add -llog to your linker flags + + Note that ndk-build does that for your automatically. + +3/ Keep in mind that there is no /tmp directory on Android. + + If you use the library from a regular Android applications, specify a + path under your app-specific storage directory. An alternative is to + store them on the SDCard, but this requires a specific permission. + +For a concrete example, see the sample test application under +android/sample_app. See its README for more information. + + +III. Getting a stack trace on the host: +======================================= + +This process is similar to other platforms, but here's a quick example: + +1/ Retrieve the minidumps on your development machine. + +2/ Dump the symbols for your native libraries with the 'dump_syms' tool. + This first requires building the host version of Google Breakpad, then + calling: + + dump_syms $PROJECT_PATH/obj/local/$ABI/libfoo.so > libfoo.so.sym + +3/ Create the symbol directory hierarchy. + + The first line of the generated libfoo.so.sym will have a "MODULE" + entry that carries a hexadecimal version number, e.g.: + + MODULE Linux arm D51B4A5504974FA6ECC1869CAEE3603B0 test_google_breakpad + + Note: The second field could be either 'Linux' or 'Android'. + + Extract the version number, and a 'symbol' directory, for example: + + $PROJECT_PATH/symbols/libfoo.so/$VERSION/ + + Copy/Move your libfoo.sym file there. + +4/ Invoke minidump_stackwalk to create the stack trace: + + minidump_stackwalk $MINIDUMP_FILE $PROJECT_PATH/symbols + +Note that various helper scripts can be found on the web to automate these +steps. + +IV. Verifying the Android build library: +======================================== + +If you modify Google Breakpad and want to check that it still works correctly +on Android, please run the android/run-checks.sh script which will do all +necessary verifications for you. This includes: + + - Rebuilding the full host binaries. + - Rebuilding the full Android binaries with configure/make. + - Rebuilding the client library unit tests, and running them on a device. + - Rebuilding the client library with ndk-build. + - Building, installing and running a test crasher program on a device. + - Extracting the corresponding minidump, dumping the test program symbols + and generating a stack trace. + - Checking the generated stack trace for valid source locations. + +For more details, please run: + + android/run-checks.sh --help-all diff --git a/shared/sentry/external/breakpad/README.md b/shared/sentry/external/breakpad/README.md new file mode 100644 index 000000000..a9094a27a --- /dev/null +++ b/shared/sentry/external/breakpad/README.md @@ -0,0 +1,82 @@ +# Breakpad + +Breakpad is a set of client and server components which implement a +crash-reporting system. + +* [Homepage](https://chromium.googlesource.com/breakpad/breakpad/) +* [Documentation](./docs/) +* [Bugs](https://bugs.chromium.org/p/google-breakpad/) +* Discussion/Questions: [google-breakpad-discuss@googlegroups.com](https://groups.google.com/d/forum/google-breakpad-discuss) +* Developer/Reviews: [google-breakpad-dev@googlegroups.com](https://groups.google.com/d/forum/google-breakpad-dev) +* Tests: [![Build+Test CI](https://github.com/google/breakpad/actions/workflows/build-test-ci.yml/badge.svg)](https://github.com/google/breakpad/actions/workflows/build-test-ci.yml) [![Build status](https://ci.appveyor.com/api/projects/status/eguv4emv2rhq68u2?svg=true)](https://ci.appveyor.com/project/vapier/breakpad) +* Coverage [![Coverity Status](https://scan.coverity.com/projects/9215/badge.svg)](https://scan.coverity.com/projects/google-breakpad) + +## Getting started (from main) + +1.

Build the source. + + ```sh + ./configure && make + ``` + + You can also cd to another directory and run configure from there to build + outside the source tree. + + This will build the processor tools (`src/processor/minidump_stackwalk`, + `src/processor/minidump_dump`, etc), and when building on Linux it will + also build the client libraries and some tools + (`src/tools/linux/dump_syms/dump_syms`, + `src/tools/linux/md2core/minidump-2-core`, etc). + +5. Optionally, run tests. + + ```sh + make check + ``` + +6. Optionally, install the built libraries + + ```sh + make install + ``` + +If you need to reconfigure your build be sure to run `make distclean` first. + +To update an existing checkout to a newer revision, you can +`git pull` as usual, but then you should run `gclient sync` to ensure that the +dependent repos are up-to-date. + +## To request change review + +1. Follow the steps above to get the source and build it. + +2. Make changes.

These tasks are +divided between the “handler†(short for “exception handlerâ€) library linked in +to an application being monitored for crashes, and the “sender†library, +intended to be linked in to a separate external program. + +## Background + +As one of the chief tasks of the client handler is to generate a dump, an +understanding of [dump files](processor_design.md) will aid in understanding the +handler. + +## Overview + +Breakpad provides client libraries for each of its target platforms. Currently, +these exist for Windows on x86 and Mac OS X on both x86 and PowerPC. A Linux +implementation has been written and is currently under review. + +Because the mechanisms for catching exceptions and the methods for obtaining the +information that a dump contains vary between operating systems, each target +operating system requires a completely different handler implementation. Where +multiple CPUs are supported for a single operating system, the handler +implementation will likely also require separate code for each processor type to +extract CPU-specific information. One of the goals of the Breakpad handler is to +provide a prepackaged cross-platform system that masks many of these +system-level differences and quirks from the application developer. Although the +underlying implementations differ, the handler library for each system follows +the same set of principles and exposes a similar interface. + +Code that wishes to take advantage of Breakpad should be linked against the +handler library, and should, at an appropriate time, install a Breakpad handler. +For applications, it is generally desirable to install the handler as early in +the start-up process as possible. Developers of library code using Breakpad to +monitor itself may wish to install a Breakpad handler when the library is +loaded, or may only want to install a handler when calls are made in to the +library. + +The handler can be triggered to generate a dump either by catching an exception +or at the request of the application itself. The latter case may be useful in +debugging assertions or other conditions where developers want to know how a +program got in to a specific non-crash state. After generating a dump, the +handler calls a user-specified callback function. The callback function may +collect additional data about the program’s state, quit the program, launch a +crash reporter application, or perform other tasks. Allowing for this +functionality to be dictated by a callback function preserves flexibility. + +The sender library is also has a separate implementation for each supported +platform, because of the varying interfaces for accessing network resources on +different operating systems. The sender transmits a dump along with other +application-defined information to a crash report server via HTTP. Because dumps +may contain sensitive data, the sender allows for the use of HTTPS. + +The canonical example of the entire client system would be for a monitored +application to link against the handler library, install a Breakpad handler from +its main function, and provide a callback to launch a small crash reporter +program. The crash reporter program would be linked against the sender library, +and would send the crash dump when launched. A separate process is recommended +for this function because of the unreliability inherent in doing any significant +amount of work from a crashed process. + +## Detailed Design + +### Exception Handler Installation + +The mechanisms for installing an exception handler vary between operating +systems. On Windows, it’s a relatively simple matter of making one call to +register a [top-level exception +filter](http://msdn.microsoft.com/library/en-us/debug/base/setunhandledexceptionfilter.asp) +callback function. On most Unix-like systems such as Linux, processes are +informed of exceptions by the delivery of a signal, so an exception handler +takes the form of a signal handler. The native mechanism to catch exceptions on +Mac OS X requires a large amount of code to set up a Mach port, identify it as +the exception port, and assign a thread to listen for an exception on that port. +Just as the preparation of exception handlers differ, the manner in which they +are called differs as well. On Windows and most Unix-like systems, the handler +is called on the thread that caused the exception. On Mac OS X, the thread +listening to the exception port is notified that an exception has occurred. The +different implementations of the Breakpad handler libraries perform these tasks +in the appropriate ways on each platform, while exposing a similar interface on +each. + +A Breakpad handler is embodied in an `ExceptionHandler` object. Because it’s a +C++ object, `ExceptionHandler`s may be created as local variables, allowing them +to be installed and removed as functions are called and return. This provides +one possible way for a developer to monitor only a portion of an application for +crashes. + +### Exception Basics + +Once an application encounters an exception, it is in an indeterminate and +possibly hazardous state. Consequently, any code that runs after an exception +occurs must take extreme care to avoid performing operations that might fail, +hang, or cause additional exceptions. This task is not at all straightforward, +and the Breakpad handler library seeks to do it properly, accounting for all of +the minute details while allowing other application developers, even those with +little systems programming experience, to reap the benefits. All of the Breakpad +handler code that executes after an exception occurs has been written according +to the following guidelines for safety at exception time: + +* Use of the application heap is forbidden. The heap may be corrupt or + otherwise unusable, and allocators may not function. +* Resource allocation must be severely limited. The handler may create a new + file to contain the dump, and it may attempt to launch a process to continue + handling the crash. +* Execution on the thread that caused the exception is significantly limited. + The only code permitted to execute on this thread is the code necessary to + transition handling to a dedicated preallocated handler thread, and the code + to return from the exception handler. +* Handlers shouldn’t handle crashes by attempting to walk stacks themselves, + as stacks may be in inconsistent states. Dump generation should be performed + by interfacing with the operating system’s memory manager and code module + manager. +* Library code, including runtime library code, must be avoided unless it + provably meets the above guidelines. For example, this means that the STL + string class may not be used, because it performs operations that attempt to + allocate and use heap memory. It also means that many C runtime functions + must be avoided, particularly on Windows, because of heap operations that + they may perform. + +A dedicated handler thread is used to preserve the state of the exception thread +when an exception occurs: during dump generation, it is difficult if not +impossible for a thread to accurately capture its own state. Performing all +exception-handling functions on a separate thread is also critical when handling +stack-limit-exceeded exceptions. It would be hazardous to run out of stack space +while attempting to handle an exception. Because of the rule against allocating +resources at exception time, the Breakpad handler library creates its handler +thread when it installs its exception handler. On Mac OS X, this handler thread +is created during the normal setup of the exception handler, and the handler +thread will be signaled directly in the event of an exception. On Windows and +Linux, the handler thread is signaled by a small amount of code that executes on +the exception thread. Because the code that executes on the exception thread in +this case is small and safe, this does not pose a problem. Even when an +exception is caused by exceeding stack size limits, this code is sufficiently +compact to execute entirely within the stack’s guard page without causing an +exception. + +The handler thread may also be triggered directly by a user call, even when no +exception occurs, to allow dumps to be generated at any point deemed +interesting. + +### Filter Callback + +When the handler thread begins handling an exception, it calls an optional +user-defined filter callback function, which is responsible for judging whether +Breakpad’s handler should continue handling the exception or not. This mechanism +is provided for the benefit of library or plug-in code, whose developers may not +be interested in reports of crashes that occur outside of their modules but +within processes hosting their code. If the filter callback indicates that it is +not interested in the exception, the Breakpad handler arranges for it to be +delivered to any previously-installed handler. + +### Dump Generation + +Assuming that the filter callback approves (or does not exist), the handler +writes a dump in a directory specified by the application developer when the +handler was installed, using a previously generated unique identifier to avoid +name collisions. The mechanics of dump generation also vary between platforms, +but in general, the process involves enumerating each thread of execution, and +capturing its state, including processor context and the active portion of its +stack area. The dump also includes a list of the code modules loaded in to the +application, and an indicator of which thread generated the exception or +requested the dump. In order to avoid allocating memory during this process, the +dump is written in place on disk. + +### Post-Dump Behavior + +Upon completion of writing the dump, a second callback function is called. This +callback may be used to launch a separate crash reporting program or to collect +additional data from the application. The callback may also be used to influence +whether Breakpad will treat the exception as handled or unhandled. Even after a +dump is successfully generated, Breakpad can be made to behave as though it +didn’t actually handle an exception. This function may be useful for developers +who want to test their applications with Breakpad enabled but still retain the +ability to use traditional debugging techniques. It also allows a +Breakpad-enabled application to coexist with a platform’s native crash reporting +system, such as Mac OS X’ [CrashReporter](http://developer.apple.com/technotes/tn2004/tn2123.html) +and [Windows Error Reporting](http://msdn.microsoft.com/isv/resources/wer/). + +Typically, when Breakpad handles an exception fully and no debuggers are +involved, the crashed process will terminate. + +Authors of both callback functions that execute within a Breakpad handler are +cautioned that their code will be run at exception time, and that as a result, +they should observe the same programming practices that the Breakpad handler +itself adheres to. Notably, if a callback is to be used to collect additional +data from an application, it should take care to read only “safe†data. This +might involve accessing only static memory locations that are updated +periodically during the course of normal program execution. + +### Sender Library + +The Breakpad sender library provides a single function to send a crash report to +a crash server. It accepts a crash server’s URL, a map of key-value parameters +that will accompany the dump, and the path to a dump file itself. Each of the +key-value parameters and the dump file are sent as distinct parts of a multipart +HTTP POST request to the specified URL using the platform’s native HTTP +facilities. On Linux, [libcurl](http://curl.haxx.se/) is used for this function, +as it is the closest thing to a standard HTTP library available on that +platform. + +## Future Plans + +Although we’ve had great success with in-process dump generation by following +our guidelines for safe code at exception time, we are exploring options for +allowing dumps to be generated in a separate process, to further enhance the +handler library’s robustness. + +On Windows, we intend to offer tools to make it easier for Breakpad’s settings +to be managed by the native group policy management system. + +We also plan to offer tools that many developers would find desirable in the +context of handling crashes, such as a mechanism to determine at launch if the +program last terminated in a crash, and a way to calculate “crashiness†in terms +of crashes over time or the number of application launches between crashes. + +We are also investigating methods to capture crashes that occur early in an +application’s launch sequence, including crashes that occur before a program’s +main function begins executing. diff --git a/shared/sentry/external/breakpad/docs/contributing_to_breakpad.md b/shared/sentry/external/breakpad/docs/contributing_to_breakpad.md new file mode 100644 index 000000000..b8d261e99 --- /dev/null +++ b/shared/sentry/external/breakpad/docs/contributing_to_breakpad.md @@ -0,0 +1,35 @@ +# Introduction + +Thanks for thinking of contributing to Breakpad!

TODO: More on first and second change and vectored v. try/catch. + +There are two main types of exceptions across all platforms: in-process and +out-of-process. + +# In-Process + +In process exception handling is relatively simple since the crashing process +handles crash reporting. It is generally considered unsafe to write a minidump +from a crashed process. For example, key data structures could be corrupted or +the stack on which the exception handler runs could have been overwritten. For +this reason all platforms also support some level of out-of-process exception +handling. + +## Windows + +In-process exception handling Breakpad creates a 'handler head' that waits +infinitely on a semaphore at start up. When this thread is woken it writes the +minidump and signals to the excepting thread that it may continue. A filter will +tell the OS to kill the process if the minidump is written successfully. +Otherwise it continues. + +# Out-of-Process + +Out-of-process exception handling is more complicated than in-process exception +handling because of the need to set up a separate process that can read the +state of the crashing process. + +## Windows + +Breakpad uses two abstractions around the exception handler to make things work: +`CrashGenerationServer` and `CrashGenerationClient`. The constructor for these +takes a named pipe name. + +During server start up a named pipe and registers callbacks for client +connections are created. The named pipe is used for registration and all IO on +the pipe is done asynchronously. `OnPipeConnected` is called when a client +attempts to connect (call `CreateFile` on the pipe). `OnPipeConnected` does the +state machine transition from `Initial` to `Connecting` and on through +`Reading`, `Reading_Done`, `Writing`, `Writing_Done`, `Reading_ACK`, and +`Disconnecting`. + +When registering callbacks, the client passes in two pointers to pointers: 1. A +pointer to the `EXCEPTION_INFO` pointer 1. A pointer to the `MDRawAssertionInfo` +which handles various non-exception failures like assertions + +The essence of registration is adding a "`ClientInfo`" object that contains +handles used for synchronization with the crashing process to an array +maintained by the server. This is how we can keep track of all the clients on +the system that have registered for minidumps. These handles are: * +`server_died(mutex)` * `dump_requested(Event)` * `dump_generated(Event)` + +The server registers asynchronous waits on these events with the `ClientInfo` +object as the callback context. When the `dump_requested` event is set by the +client, the `OnDumpRequested()` callback is called. The server uses the handles +inside `ClientInfo` to communicate with the child process. Once the child sets +the event, it waits for two objects: 1. the `dump_generated` event 1. the +`server_died` mutex + +In the end handles are "duped" into the client process, and the clients use +`SetEvent` to request events, wait on the other event, or the `server_died` +mutex. + +## Linux + +### Current Status + +As of July 2011, Linux had a minidump generator that is not entirely +out-of-process. The minidump was generated from a separate process, but one that +shared an address space, file descriptors, signal handles and much else with the +crashing process. It worked by using the `clone()` system call to duplicate the +crashing process, and then uses `ptrace()` and the `/proc` file system to +retrieve the information required to write the minidump. Since then Breakpad has +updated Linux exception handling to provide more benefits of out-of-process +report generation. + +### Proposed Design + +#### Overview + +Breakpad would use a per-user daemon to write out a minidump that does not have, +interact with or depend on the crashing process. We don't want to start a new +separate process every time a user launches a Breakpad-enabled process. Doing +one daemon per machine is unacceptable for security concerns around one user +being able to initiate a minidump generation for another user's process. + +#### Client/Server Communication + +On Breakpad initialization in a process, the initializer would check if the +daemon is running and, if not, start it. The race condition between the check +and the initialization is not a problem because multiple daemons can check if +the IPC endpoint already exists and if a server is listening. Even if multiple +copies of the daemon try to `bind()` the filesystem to name the socket, all but +one will fail and can terminate. + +This point is relevant for error handling conditions. Linux does not clean the +file system representation of a UNIX domain socket even if both endpoints +terminate, so checking for existence is not strong enough. However checking the +process list or sending a ping on the socket can handle this. + +Breakpad uses UNIX domain sockets since they support full duplex communication +(unlike Windows, named pipes on Linux are half) and the kernal automatically +creates a private channel between the client and server once the client calls +`connect()`. + +#### Minidump Generation + +Breakpad could use the current system with `ptrace()` and `/proc` within the +daemon executable. + +Overall the operations look like: 1. Signal from OS indicating crash 1. Signal +Handler suspends all threads except itself 1. Signal Handler sends +`CRASH_DUMP_REQUEST` message to server and waits for response 1. Server inspects +1. Minidump is asynchronously written to disk by the server 1. Server responds +indicating inspection is done + +## Mac OSX + +Out-of-process exception handling is fully supported on Mac. diff --git a/shared/sentry/external/breakpad/docs/getting_started_with_breakpad.md b/shared/sentry/external/breakpad/docs/getting_started_with_breakpad.md new file mode 100644 index 000000000..b827d401f --- /dev/null +++ b/shared/sentry/external/breakpad/docs/getting_started_with_breakpad.md @@ -0,0 +1,115 @@ +# Introduction + +Breakpad is a library and tool suite that allows you to distribute an +application to users with compiler-provided debugging information removed, +record crashes in compact "minidump" files, send them back to your server, and +produce C and C++ stack traces from these minidumps. Breakpad can also write +minidumps on request for programs that have not crashed. + +Breakpad is currently used by Google Chrome, Firefox, Google Picasa, Camino, +Google Earth, and other projects. + +![Workflow](breakpad.png) + +Breakpad has three main components: + +* The **client** is a library that you include in your application.

You can configure + the client to write a minidump when a crash occurs, or when explicitly + requested. + +* The **symbol dumper** is a program that reads the debugging information + produced by the compiler and produces a **symbol file**, in [Breakpad's own + format](symbol_files.md). + +* The **processor** is a program that reads a minidump file, finds the + appropriate symbol files for the versions of the executables and shared + libraries the minidump mentions, and produces a human-readable C/C++ stack + trace. + +# The minidump file format + +The minidump file format is similar to core files but was developed by Microsoft +for its crash-uploading facility. A minidump file contains: + +* A list of the executable and shared libraries that were loaded in the + process at the time the dump was created. This list includes both file names + and identifiers for the particular versions of those files that were loaded. + +* A list of threads present in the process. For each thread, the minidump + includes the state of the processor registers, and the contents of the + threads' stack memory. These data are uninterpreted byte streams, as the + Breakpad client generally has no debugging information available to produce + function names or line numbers, or even identify stack frame boundaries. + +* Other information about the system on which the dump was collected: + processor and operating system versions, the reason for the dump, and so on. + +Breakpad uses Windows minidump files on all platforms, instead of the +traditional core files, for several reasons: + +* Core files can be very large, making them impractical to send across a + network to the collector for processing. Minidumps are smaller, as they were + designed to be used this way. + +* The core file format is poorly documented. For example, the Linux Standards + Base does not describe how registers are stored in `PT_NOTE` segments. + +* It is harder to persuade a Windows machine to produce a core dump file than + it is to persuade other machines to write a minidump file. + +* It simplifies the Breakpad processor to support only one file format. + +# Overview/Life of a minidump + +A minidump is generated via calls into the Breakpad library. By default, +initializing Breakpad installs an exception/signal handler that writes a +minidump to disk at exception time. On Windows, this is done via +`SetUnhandledExceptionFilter()`; on OS X, this is done by creating a thread that +waits on the Mach exception port; and on Linux, this is done by installing a +signal handler for various exceptions like `SIGILL, SIGSEGV` etc. + +Once the minidump is generated, each platform has a slightly different way of +uploading the crash dump. On Windows & Linux, a separate library of functions is +provided that can be called into to do the upload. On OS X, a separate process +is spawned that prompts the user for permission, if configured to do so, and +sends the file. + +# Terminology + +**In-process vs. out-of-process exception handling** - it's generally considered +that writing the minidump from within the crashed process is unsafe - key +process data structures could be corrupted, or the stack on which the exception +handler runs could have been overwritten, etc. All 3 platforms support what's +known as "out-of-process" exception handling. + +# Integration overview + +## Breakpad Code Overview + +All the client-side code is found by visiting the Google Project at +https://chromium.googlesource.com/breakpad/breakpad.

After processing, this data is made available to users of the library. + +## Background + +The Breakpad processor is intended to sit at the core of a comprehensive +crash-reporting system that does not require debugging information to be +provided to those running applications being monitored. Some existing +crash-reporting systems, such as [GNOME](http://www.gnome.org/)’s Bug-Buddy and +[Apple](http://www.apple.com/)’s +[CrashReporter](http://developer.apple.com/technotes/tn2004/tn2123.html), +require symbolic +information to be present on the end user’s computer; in the case of +CrashReporter, the reports are transmitted only to Apple, not to third-party +developers. Other systems, such as [Microsoft](http://www.microsoft.com/)’s +[Windows Error Reporting](http://msdn.microsoft.com/isv/resources/wer/) and +SupportSoft’s Talkback, transmit only a snapshot of a crashed process’ state, +which can later be combined with symbolic debugging information without the need +for it to be present on end users’ computers. Because symbolic debugging +information consumes a large amount of space and is otherwise not needed during +the normal operation of software, and because some developers are reluctant to +release debugging symbols to their customers, Breakpad follows the latter +approach. + +We know of no currently-maintained crash-reporting systems that meet our +requirements, which are to: * allow for symbols to be separate from the +application, * handle crash reports from multiple platforms, * allow developers +to operate their own crash-reporting platform, and to * be open-source. Windows +Error Reporting only functions for Microsoft products, and requires the +involvement of Microsoft’s servers. Talkback, while cross-platform, has not been +maintained and at this point does not support Mac OS X on x86, which we consider +to be a significant platform. Talkback is also closed-source commercial +software, and has very specific requirements for its server platform. + +We are aware of Windows-only crash-reporting systems that leverage Microsoft’s +debugging interfaces. Such systems, even if extended to support dumps from other +platforms, are tied to using Windows for at least a portion of the processor +platform. + +## Overview + +The Breakpad processor itself is written in standard C++ and will work on a +variety of platforms. The dumps it accepts may also have been created on a +variety of systems. The library is able to combine dumps with symbolic debugging +information to create stack traces that include function signatures. The +processor library includes simple command-line tools to examine dumps and +process them, producing stack traces. It also exposes several layers of APIs +enabling crash-reporting systems to be built around the Breakpad processor. + +## Detailed Design + +### Dump Files + +In the processor, the dump data is of primary significance. Dumps typically +contain: + +* CPU context (register data) as it was at the time the crash occurred, and an + indication of which thread caused the crash. General-purpose registers are + included, as are special-purpose registers such as the instruction pointer + (program counter). +* Information about each thread of execution within a crashed process, + including: + * The memory region used for each thread’s stack. + * CPU context for each thread, which for various reasons is not the same + as the crash context in the case of the crashed thread. +* A list of loaded code segments (or modules), including: + * The name of the file (`.so`, `.exe`, `.dll`, etc.) which provides the + code. + * The boundaries of the memory region in which the code segment is visible + to the process. + * A reference to the debugging information for the code module, when such + information is available. + +Ordinarily, dumps are produced as a result of a crash, but other triggers may be +set to produce dumps at any time a developer deems appropriate. The Breakpad +processor can handle dumps in the minidump format, either generated by an +[Breakpad client “handlerâ€](client_design.md) implementation, or by another +implementation that produces dumps in this format. The +[DbgHelp.dll!MiniDumpWriteDump](http://msdn2.microsoft.com/en-us/library/ms680360.aspx) +function on Windows +produces dumps in this format, and is the basis for the Breakpad handler +implementation on that platform. + +The [minidump format](http://msdn.microsoft.com/en-us/library/ms679293%28VS.85%29.aspx) is +essentially a simple container format, organized as a series of streams. Each +stream contains some type of data relevant to the crash. A typical “normal†+minidump contains streams for the thread list, the module list, the CPU context +at the time of the crash, and various bits of additional system information. +Other types of minidump can be generated, such as a full-memory minidump, which +in addition to stack memory contains snapshots of all of a process’ mapped +memory regions. + +The minidump format was chosen as Breakpad’s dump format because it has an +established track record on Windows, and it can be adapted to meet the needs of +the other platforms that Breakpad supports. Most other operating systems use +“core†files as their native dump formats, but the capabilities of core files +vary across platforms, and because core files are usually presented in a +platform’s native executable format, there are complications involved in +accessing the data contained therein without the benefit of the header files +that define an executable format’s entire structure. Because minidumps are +leaner than a typical executable format, a redefinition of the format in a +cross-platform header file, `minidump_format.h`, was a straightforward task. +Similarly, the capabilities of the minidump format are understood, and because +it provides an extensible container, any of Breakpad’s needs that could not be +met directly by the standard minidump format could likely be met by extending it +as needed. Finally, using this format means that the dump file is compatible +with native debugging tools at least on Windows. A possible future avenue for +exploration is the conversion of minidumps to core files, to enable this same +benefit on other platforms. + +We have already provided an extension to the minidump format that allows it to +carry dumps generated on systems with PowerPC processors. The format already +allows for variable CPUs, so our work in this area was limited to defining a +context structure sufficient to represent the execution state of a PowerPC. We +have also defined an extension that allows minidumps to indicate which thread of +execution requested a dump be produced for non-crash dumps. + +Often, the information contained within a dump alone is sufficient to produce a +full stack backtrace for each thread. Certain optimizations that compilers +employ in producing code frustrate this process. Specifically, the “frame +pointer omission†optimization of x86 compilers can make it impossible to +produce useful stack traces given only a stack snapshot and CPU context. In +these cases, however, compiler-emitted debugging information can aid in +producing useful stack traces. The Breakpad processor is able to take advantage +of this debugging information as supplied by Microsoft’s C/C++ compiler, the +only compiler to apply such optimizations by default. As a result, the Breakpad +processor can produce useful stack traces even from code with frame pointer +omission optimizations as produced by this compiler. + +### Symbol Files + +The [symbol files](symbol_files.md) that the Breakpad processor accepts allow +for frame pointer omission data, but this is only one of their capabilities. +Each symbol file also includes information about the functions, source files, +and source code line numbers for a single module of code. A module is an +individually-loadble chunk of code: these can be executables containing a main +program (`exe` files on Windows) or shared libraries (`.so` files on Linux, +`.dylib` files, frameworks, and bundles on Mac OS X, and `.dll` files on +Windows). Dumps contain information about which of these modules were loaded at +the time the dump was produced, and given this information, the Breakpad +processor attempts to locate debugging symbols for the module through a +user-supplied function embodied in a “symbol supplier.†Breakpad includes a +sample symbol supplier, called `SimpleSymbolSupplier`, that is used by its +command-line tools; this supplier locates symbol files by pathname. +`SimpleSymbolSupplier` is also available to other users of the Breakpad +processor library. This allows for the use of a simple reference implementation, +but preserves flexibility for users who may have more demanding symbol file +storage needs. + +Breakpad’s symbol file format is text-based, and was defined to be fairly +human-readable and to encompass the needs of multiple platforms. The Breakpad +processor itself does not operate directly with native symbol formats +([DWARF](http://dwarf.freestandards.org/) and +[STABS](http://sourceware.org/gdb/current/onlinedocs/stabs.html) +on most Unix-like systems, +[.pdb files](http://msdn2.microsoft.com/en-us/library/yd4f8bd1(VS.80).aspx) +on Windows), +because of the complications in accessing potentially complex symbol formats +with slight variations between platforms, stored within different types of +binary formats. In the case of `.pdb` files, the debugging format is not even +documented. Instead, Breakpad’s symbol files are produced on each platform, +using specific debugging APIs where available, to convert native symbols to +Breakpad’s cross-platform format. + +### Processing + +Most commonly, a developer will enable an application to use Breakpad by +building it with a platform-specific [client “handlerâ€](client_design.md) +library. After building the application, the developer will create symbol files +for Breakpad’s use using the included `dump_syms` or `symupload` tools, or +another suitable tool, and place the symbol files where the processor’s symbol +supplier will be able to locate them. + +When a dump file is given to the processor’s `MinidumpProcessor` class, it will +read it using its included minidump reader, contained in the `Minidump` family +of classes. It will collect information about the operating system and CPU that +produced the dump, and determine whether the dump was produced as a result of a +crash or at the direct request of the application itself. It then loops over all +of the threads in a process, attempting to walk the stack associated with each +thread. This process is achieved by the processor’s `Stackwalker` components, of +which there are a slightly different implementations for each CPU type that the +processor is able to handle dumps from. Beginning with a thread’s context, and +possibly using debugging data, the stackwalker produces a list of stack frames, +containing each instruction executed in the chain. These instructions are +matched up with the modules that contributed them to a process, and the +`SymbolSupplier` is invoked to locate a symbol file. The symbol file is given to +a `SourceLineResolver`, which matches the instruction up with a specific +function name, source file, and line number, resulting in a representation of a +stack frame that can easily be used to identify which code was executing. + +The results of processing are made available in a `ProcessState` object, which +contains a vector of threads, each containing a vector of stack frames. + +For small-scale use of the Breakpad processor, and for testing and debugging, +the `minidump_stackwalk` tool is provided. It invokes the processor and displays +the full results of processing, optionally allowing symbols to be provided to +the processor by a pathname-based symbol supplier, `SimpleSymbolSupplier`. + +For lower-level testing and debugging, the processor library also includes a +`minidump_dump` tool, which walks through an entire minidump file and displays +its contents in somewhat readable form. + +### Platform Support + +The Breakpad processor library is able to process dumps produced on Mac OS X +systems running on x86, x86-64, and PowerPC processors, on Windows and Linux +systems running on x86 or x86-64 processors, and on Android systems running ARM +or x86 processors. The processor library itself is written in standard C++, and +should function properly in most Unix-like environments. It has been tested on +Linux and Mac OS X. + +## Future Plans + +There are currently no firm plans or timetables to implement any of these +features, although they are possible avenues for future exploration. + +The symbol file format can be extended to carry information about the locations +of parameters and local variables as stored in stack frames and registers, and +the processor can use this information to provide enhanced stack traces showing +function arguments and variable values. + +On Mac OS X and Linux, we can provide tools to convert files from the minidump +format into the native core format. This will enable developers to open dump +files in a native debugger, just as they are presently able to do with minidumps +on Windows. diff --git a/shared/sentry/external/breakpad/docs/stack_walking.md b/shared/sentry/external/breakpad/docs/stack_walking.md new file mode 100644 index 000000000..941115946 --- /dev/null +++ b/shared/sentry/external/breakpad/docs/stack_walking.md @@ -0,0 +1,144 @@ +# Introduction + +This page aims to provide a detailed description of how Breakpad produces stack +traces from the information contained within a minidump file. + +# Details + +## Starting the Process + +Typically the stack walking process is initiated by instantiating the +[MinidumpProcessor](../src/processor/minidump_processor.cc) +class and calling the [MinidumpProcessor::Process](../src/processor/minidump_processor.cc#61) +method, providing it a minidump file to process. To produce a useful stack +trace, the MinidumpProcessor requires two other objects which are passed in its +constructor: a [SymbolSupplier](../src/google_breakpad/processor/symbol_supplier.h) +and a [SourceLineResolverInterface](../src/google_breakpad/processor/source_line_resolver_interface.h). +The SymbolSupplier object is responsible for locating and providing SymbolFiles +that match modules from the minidump. The SourceLineResolverInterface is +responsible for loading the symbol files and using the information contained +within to provide function and source information for stack frames, as well as +information on how to unwind from a stack frame to its caller. More detail will +be provided on these interactions later. + +A number of data streams are extracted from the minidump to begin stack walking: +the list of threads from the process +([MinidumpThreadList](../src/google_breakpad/processor/minidump.h#335)), +the list of modules loaded in the process +([MinidumpModuleList](../src/google_breakpad/processor/minidump.h#501)), +and information about the exception that caused the process to crash +([MinidumpException](../src/google_breakpad/processor/minidump.h#615)). + +## Enumerating Threads + +For each thread in the thread list +([MinidumpThread](../src/google_breakpad/processor/minidump.h#299)), +the thread memory containing the stack for the thread +([MinidumpMemoryRegion](../src/google_breakpad/processor/minidump.h#236)) +and the CPU context representing the CPU state of the thread at the time the +dump was written ([MinidumpContext](../src/google_breakpad/processor/minidump.h#171)) +are extracted from the minidump. If the thread being processed is the thread +that produced the exception then a CPU context is obtained from the +MinidumpException object instead, which represents the CPU state of the thread +at the point of the exception. A stack walker is then instantiated by calling +the [Stackwalker::StackwalkerForCPU](../src/google_breakpad/processor/stackwalker.h#77) +method and passing it the CPU context, the thread memory, the module list, as +well as the SymbolSupplier and SourceLineResolverInterface. This method selects +the specific !Stackwalker subclass based on the CPU architecture of the provided +CPU context and returns an instance of that subclass. + +## Walking a thread's stack + +Once a !Stackwalker instance has been obtained, the processor calls the +[Stackwalker::Walk](../src/google_breakpad/processor/source_line_resolver_interface.h) +method to obtain a list of frames representing the stack of this thread. The +!Stackwalker starts by calling the GetContextFrame method which returns a +StackFrame representing the top of the stack, with CPU state provided by the +initial CPU context. From there, the stack walker repeats the following steps +for each frame in turn: + +### Finding the Module + +The address of the instruction pointer of the current frame is used to determine +which module contains the current frame by calling the module list's +[GetModuleForAddress](../src/google_breakpad/processor/code_modules.h#56) method. + +### Locating Symbols + +If a module is located, the SymbolSupplier is asked to locate symbols +corresponding to the module by calling its +[GetCStringSymbolData](../src/google_breakpad/processor/symbol_supplier.h#87) +method. Typically this is implemented by using the module's debug filename (the +PDB filename for Windows dumps) and debug identifier (a GUID plus one extra +digit) as a lookup key. The [SimpleSymbolSupplier](../src/processor/simple_symbol_supplier.cc) +class simply uses these as parts of a file path to locate a flat file on disk. + +### Loading Symbols + +If a symbol file is located, the SourceLineResolverInterface is then asked to +load the symbol file by calling its +[LoadModuleUsingMemoryBuffer](../src/google_breakpad/processor/source_line_resolver_interface.h#71) +method. The [BasicSourceLineResolver](../src/processor/basic_source_line_resolver.cc) +implementation parses the text-format [symbol file](symbol_files.md) into +in-memory data structures to make lookups by address of function names, source +line information, and unwind information easy. + +### Getting source line information + +If a symbol file has been successfully loaded, the SourceLineResolverInterface's +[FillSourceLineInfo](../src/google_breakpad/processor/source_line_resolver_interface.h#89) +method is called to provide a function name and source line information for the +current frame. This is done by subtracting the base address of the module +containing the current frame from the instruction pointer of the current frame +to obtain a relative virtual address (RVA), which is a code offset relative to +the start of the module. This RVA is then used as a lookup into a table of +functions ([FUNC lines](SymbolFiles#FUNC_records.md) from the symbol file), each +of which has an associated address range (function start address, function +size). If a function is found whose address range contains the RVA, then its +name is used. The RVA is then used as a lookup into a table of source lines +([line records](SymbolFiles#Line_records.md) from the symbol file), each of +which also has an associated address range. If a match is found it will provide +the file name and source line associated with the current frame. If no match was +found in the function table, another table of publicly exported symbols may be +consulted ([PUBLIC lines](SymbolFiles#PUBLIC_records.md) from the symbol file). +Public symbols contain only a start address, so the lookup simply looks for the +nearest symbol that is less than the provided RVA. + +### Finding the caller frame + +To find the next frame in the stack, the !Stackwalker calls its +[GetCallerFrame](../src/google_breakpad/processor/stackwalker.h#186) +method, passing in the current frame. Each !Stackwalker subclass implements +GetCallerFrame differently, but there are common patterns. + +Typically the first step is to query the SourceLineResolverInterface for the +presence of detailed unwind information. This is done using its +[FindWindowsFrameInfo](../src/google_breakpad/processor/source_line_resolver_interface.h#96) +and [FindCFIFrameInfo](../src/google_breakpad/processor/source_line_resolver_interface.h#102) +methods. These methods look for Windows unwind info extracted from a PDB file +([STACK WIN](SymbolFiles#STACK_WIN_records.md) lines from the symbol file), or +DWARF CFI extracted from a binary ([STACK CFI](SymbolFiles#STACK_CFI_records.md) +lines from the symbol file) respectively. The information covers address ranges, +so the RVA of the current frame is used for lookup as with function and source +line information. + +If unwind info is found it provides a set of rules to recover the register state +of the caller frame given the current register state as well as the thread's +stack memory. The rules are evaluated to produce the caller frame. + +If unwind info is not found then the !Stackwalker may resort to other methods. +Typically on architectures which specify a frame pointer unwinding by +dereferencing the frame pointer is tried next. If that is successful it is used +to produce the caller frame. + +If no caller frame was found by any other method most !Stackwalker +implementations resort to stack scanning by looking at each word on the stack +down to a fixed depth (implemented in the +[Stackwalker::ScanForReturnAddress](../src/google_breakpad/processor/stackwalker.h#131) +method) and using a heuristic to attempt to find a reasonable return address +(implemented in the +[Stackwalker::InstructionAddressSeemsValid](../src/google_breakpad/processor/stackwalker.h#111) method). + +If no caller frame is found or the caller frame seems invalid, stack walking +stops. If a caller frame was found then these steps repeat using the new frame +as the current frame. diff --git a/shared/sentry/external/breakpad/docs/sym_upload_v2_protocol.md b/shared/sentry/external/breakpad/docs/sym_upload_v2_protocol.md new file mode 100644 index 000000000..d56a4c836 --- /dev/null +++ b/shared/sentry/external/breakpad/docs/sym_upload_v2_protocol.md @@ -0,0 +1,214 @@ +# Introduction + +The `sym_upload` tool is able to operate in `sym-upload-v2` protocol mode, in +addition to the legacy protocol (which will be referred to as `sym-upload-v1` +for the rest of this document).

However, minidump files contain only the +byte-by-byte contents of threads' registers and stacks, without function names +or machine-code-to-source mapping data. The processor consults Breakpad symbol +files for the information it needs to produce human-readable stack traces from +the binary-only minidump file. + +The platform-specific symbol dumping tools parse the debugging information the +compiler provides (whether as DWARF or STABS sections in an ELF file or as +stand-alone PDB files), and write that information back out in the Breakpad +symbol file format. This format is much simpler and less detailed than compiler +debugging information, and values legibility over compactness. + +# Overview + +Breakpad symbol files are ASCII text files, with lines delimited as appropriate +for the host platform. Each line is a _record_, divided into fields by single +spaces; in some cases, the last field of the record can contain spaces. The +first field is a string indicating what sort of record the line represents +(except for line records; these are very common, making them the default saves +space). Some fields hold decimal or hexadecimal numbers; hexadecimal numbers +have no "0x" prefix, and use lower-case letters. + +Breakpad symbol files contain the following record types. With some +restrictions, these may appear in any order. + +* A `MODULE` record describes the executable file or shared library from which + this data was derived, for use by symbol suppliers. A `MODULE' record should + be the first record in the file. + +* A `FILE` record gives a source file name, and assigns it a number by which + other records can refer to it. + +* An `INLINE_ORIGIN` record holds an inline function name for `INLINE` records + to refer to. + +* A `FUNC` record describes a function present in the source code. + +* An `INLINE` record describes the inline function's nest level, call site + line and call site source file to which the given ranges of machine code + should be attributed. + +* A line record indicates to which source file and line a given range of + machine code should be attributed. The line is attributed to the function + defined by the most recent `FUNC` record. + +* A `PUBLIC` record gives the address of a linker symbol. + +* A `STACK` record provides information necessary to produce stack traces. + +# `MODULE` records + +A `MODULE` record provides meta-information about the module the symbol file +describes. It has the form: + +> `MODULE` _operatingsystem_ _architecture_ _id_ _name_ + +For example: `MODULE Linux x86 D3096ED481217FD4C16B29CD9BC208BA0 firefox-bin +` These records provide meta-information about the executable or shared library +from which this symbol file was generated. A symbol supplier might use this +information to find the correct symbol files to use to interpret a given +minidump, or to perform other sorts of validation. If present, a `MODULE` record +should be the first line in the file. + +The fields are separated by spaces, and cannot contain spaces themselves, except +for _name_. + +* The _operatingsystem_ field names the operating system on which the + executable or shared library was intended to run. This field should have one + of the following values: + + | **Value** | **Meaning** | + |:----------|:--------------------| + | Linux | Linux | + | mac | Macintosh OSX | + | windows | Microsoft Windows | + +* The _architecture_ field indicates what processor architecture the + executable or shared library contains machine code for. This field should + have one of the following values: + + | **Value** | **Instruction Set Architecture** | + |:----------|:---------------------------------| + | x86 | Intel IA-32 | + | x86\_64 | AMD64/Intel 64 | + | ppc | 32-bit PowerPC | + | ppc64 | 64-bit PowerPC | + | unknown | unknown | + +* The _id_ field is a sequence of hexadecimal digits that identifies the exact + executable or library whose contents the symbol file describes. The way in + which it is computed varies from platform to platform. + +* The _name_ field contains the base name (the final component of the + directory path) of the executable or library. It may contain spaces, and + extends to the end of the line. + +# `FILE` records + +A `FILE` record holds a source file name for other records to refer to.

The _number_ field is a decimal number. The _name_ field is the name of +the file; it may contain spaces. + +# `INLINE_ORIGIN` records + +An `INLINE_ORIGIN` record holds an inline function name for `INLINE` records to +refer to. It has the form: + +> `INLINE_ORIGIN` _number_ _name_ + +For example: `INLINE_ORIGIN 2 nsQueryInterfaceWithError::operator()(nsID const&, +void**) const +` + +An `INLINE_ORIGIN` record provides the name of an inline function, and assigns +it a number which other records (`INLINE` records, in particular) can use to +refer to that function name. The _number_ field is a decimal number. The _name_ +field is the name of the inline function; it may contain spaces. + +# `FUNC` records + +A `FUNC` record describes a source-language function. It has the form: + +> `FUNC` _[m]_ _address_ _size_ _parameter\_size_ _name_ + +For example: `FUNC m c184 30 0 nsQueryInterfaceWithError::operator()(nsID const&, +void**) const +` + +The _m_ field is optional. If present it indicates that multiple symbols +reference this function's instructions. (In which case, only one symbol name is +mentioned within the breakpad file.) Multiple symbols referencing the same +instructions may occur due to identical code folding by the linker. + +The _address_ and _size_ fields are hexadecimal numbers indicating the start +address and length in bytes of the machine code instructions the function +occupies. (Breakpad symbol files cannot accurately describe functions whose code +is not contiguous.) The start address is relative to the module's load address. + +The _parameter\_size_ field is a hexadecimal number indicating the size, in +bytes, of the arguments pushed on the stack for this function. Some calling +conventions, like the Microsoft Windows `stdcall` convention, require the called +function to pop parameters passed to it on the stack from its caller before +returning. The stack walker uses this value, along with data from `STACK` +records, to step from the called function's frame to the caller's frame. + +The _name_ field is the name of the function. In languages that use linker +symbol name mangling like C++, this should be the source language name (the +"unmangled" form). This field may contain spaces. + +# `INLINE` records + +An `INLINE` record describes the inline function's nest level, call site line +and call site source file to which the given ranges of machine code should be +attributed. It has the form: + +> `INLINE` _inline_nest_level_ _call_site_line_ _call_site_file_num_ +> _origin_num_ [_address_ _size_]+ + +For example: `INLINE 0 10 3 4 d30 2a fa1 b +` + +The _inline_nest_level_ field is a decimal number that means it's inlined at the +function described by a previous `INLINE` record which has _inline_nest_level_ +one less than its.

The second `INLINE` record has +_inline_nest_level_ 1 means that it's inlined at the inline function described +by first `INLINE` record. +``` +FUNC ... +INLINE 0 ... +INLINE 1 ... +INLINE 0 ... +``` + +The _call_site_line_ and _call_site_file_num_ fields are decimal numbers +indicating where this inline function being called at. + +The _origin_num_ field refers to an `INLINE_ORIGIN` record that has the name +of the inline function. + +The _address_ and _size_ fields are hexadecimal numbers indicating the start +address and length in bytes of the machine code. The address is relative to the +module's load address. There could be more than one [_address_ _size_] range +pair, since inline functions could have discontinuous address ranges. The ranges +of an `INLINE` record are always inside the ranges described by its parent +record (a `FUNC` record or an `INLINE` record). + +The `INLINE` record is assumed to belong to the function described by the last +preceding `FUNC` record. `INLINE` records may not appear before the first `FUNC` +record. + +# Line records + +A line record describes the source file and line number to which a given range +of machine code should be attributed. It has the form: + +> _address_ _size_ _line_ _filenum_ + +For example: `c184 7 59 4 +` + +Because they are so common, line records do not begin with a string indicating +the record type. All other record types' names use upper-case letters; +hexadecimal numbers, like a line record's _address_, use lower-case letters. + +The _address_ and _size_ fields are hexadecimal numbers indicating the start +address and length in bytes of the machine code. The address is relative to the +module's load address. + +The _line_ field is the line number to which the machine code should be +attributed, in decimal; the first line of the source file is line number 1. The +_filenum_ field is a decimal number appearing in a prior `FILE` record; the name +given in that record is the source file name for the machine code. + +The line is assumed to belong to the function described by the last preceding +`FUNC` record. Line records may not appear before the first `FUNC' record. + +No two line records in a symbol file cover the same range of addresses. However, +there may be many line records with identical line and file numbers, as a given +source line may contribute many non-contiguous blocks of machine code. + +# `PUBLIC` records + +A `PUBLIC` record describes a publicly visible linker symbol, such as that used +to identify an assembly language entry point or region of memory. It has the +form: + +> PUBLIC _[m]_ _address_ _parameter\_size_ _name_ + +For example: `PUBLIC m 2160 0 Public2_1 +` + +The Breakpad processor essentially treats a `PUBLIC` record as defining a +function with no line number data and an indeterminate size: the code extends to +the next address mentioned. If a given address is covered by both a `PUBLIC` +record and a `FUNC` record, the processor uses the `FUNC` data. + +The _m_ field is optional. If present it indicates that multiple symbols +reference this function's instructions. (In which case, only one symbol name is +mentioned within the breakpad file.) Multiple symbols referencing the same +instructions may occur due to identical code folding by the linker. + +The _address_ field is a hexadecimal number indicating the symbol's address, +relative to the module's load address. + +The _parameter\_size_ field is a hexadecimal number indicating the size of the +parameters passed to the code whose entry point the symbol marks, if known. This +field has the same meaning as the _parameter\_size_ field of a `FUNC` record; +see that description for more details. + +The _name_ field is the name of the symbol. In languages that use linker symbol +name mangling like C++, this should be the source language name (the "unmangled" +form). This field may contain spaces. + +# `STACK WIN` records + +Given a stack frame, a `STACK WIN` record indicates how to find the frame that +called it. It has the form: + +> STACK WIN _type_ _rva_ _code\_size_ _prologue\_size_ _epilogue\_size_ +> _parameter\_size_ _saved\_register\_size_ _local\_size_ _max\_stack\_size_ +> _has\_program\_string_ _program\_string\_OR\_allocates\_base\_pointer_ + +For example: `STACK WIN 4 2170 14 1 0 0 0 0 0 1 $eip 4 + ^ = $esp $ebp 8 + = +$ebp $ebp ^ = +` + +All fields of a `STACK WIN` record, except for the last, are hexadecimal +numbers. + +The _type_ field indicates what sort of stack frame data this record holds. Its +value should be one of the values of the +[StackFrameTypeEnum](http://msdn.microsoft.com/en-us/library/bc5207xw%28VS.100%29.aspx) +type in Microsoft's +[Debug Interface Access (DIA)](http://msdn.microsoft.com/en-us/library/x93ctkx8%28VS.100%29.aspx) API. +Breakpad uses only records of type 4 (`FrameTypeFrameData`) and 0 +(`FrameTypeFPO`); it ignores others. These types differ only in whether the last +field is an _allocates\_base\_pointer_ flag (`FrameTypeFPO`) or a program string +(`FrameTypeFrameData`). If more than one record covers a given address, Breakpad +prefers `FrameTypeFrameData` records over `FrameTypeFPO` records. + +The _rva_ and _code\_size_ fields give the starting address and length in bytes +of the machine code covered by this record. The starting address is relative to +the module's load address. + +The _prologue\_size_ and _epilogue\_size_ fields give the length, in bytes, of +the prologue and epilogue machine code within the record's range. Breakpad does +not use these values. + +The _parameter\_size_ field gives the number of argument bytes this function +expects to have been passed. This field has the same meaning as the +_parameter\_size_ field of a `FUNC` record; see that description for more +details. + +The _saved\_register\_size_ field gives the number of bytes in the stack frame +dedicated to preserving the values of any callee-saves registers used by this +function. + +The _local\_size_ field gives the number of bytes in the stack frame dedicated +to holding the function's local variables and temporary values. + +The _max\_stack\_size_ field gives the maximum number of bytes pushed on the +stack in the frame. Breakpad does not use this value. + +If the _has\_program\_string_ field is zero, then the `STACK WIN` record's final +field is an _allocates\_base\_pointer_ flag, as a hexadecimal number; this is +expected for records whose _type_ is 0. Otherwise, the final field is a program +string. + +## Interpreting a `STACK WIN` record + +Given the register values for a frame F, we can find the calling frame as +follows: + +* If the _has\_program\_string_ field of a `STACK WIN` record is zero, then + the final field is _allocates\_base\_pointer_, a flag indicating whether the + frame uses the frame pointer register, `%ebp`, as a general-purpose + register. + * If _allocates\_base\_pointer_ is true, then `%ebp` does not point to the + frame's base address. Instead, + * Let _next\_parameter\_size_ be the parameter size of the function + frame F called (**not** this record's _parameter\_size_ field), or + zero if F is the youngest frame on the stack. You must find this + value in F's callee's `FUNC`, `STACK WIN`, or `PUBLIC` records. + * Let _frame\_size_ be the sum of the _local\_size_ field, the + _saved\_register\_size_ field, and _next\_parameter\_size_. > > With + those definitions in place, we can recover the calling frame as + follows: + * F's return address is at `%esp +`_frame\_size_, + * the caller's value of `%ebp` is saved at `%esp + +`_next\_parameter\_size_`+`_saved\_register\_size_`- 8`, and + * the caller's value of `%esp` just before the call instruction was + `%esp +`_frame\_size_`+ 4`. > > (Why do we include + _next\_parameter\_size_ in the sum when computing _frame\_size_ and + the address of the saved `%ebp`? When a function A has called a + function B, the arguments that A pushed for B are considered part of + A's stack frame: A's value for `%esp` points at the last argument + pushed for B. Thus, we must include the size of those arguments + (given by the debugging info for B) along with the size of A's + register save area and local variable area (given by the debugging + info for A) when computing the overall size of A's frame.) + * If _allocates\_base\_pointer_ is false, then F's function doesn't use + `%ebp` at all. You may recover the calling frame as above, except that + the caller's value of `%ebp` is the same as F's value for `%ebp`, so no + steps are necessary to recover it. +* If the _has\_program\_string_ field of a `STACK WIN` record is not zero, + then the record's final field is a string containing a program to be + interpreted to recover the caller's frame. The comments in the + [postfix\_evaluator.h](../src/processor/postfix_evaluator.h#40) + header file explain the language in which the program is written. You should + place the following variables in the dictionary before interpreting the + program: + * `$ebp` and `$esp` should be the values of the `%ebp` and `%esp` + registers in F. + * `.cbParams`, `.cbSavedRegs`, and `.cbLocals`, should be the values of + the `STACK WIN` record's _parameter\_size_, _saved\_register\_size_, and + _local\_size_ fields. + * `.raSearchStart` should be set to the address on the stack to begin + scanning for a return address, if necessary. The Breakpad processor sets + this to the value of `%esp` in F, plus the _frame\_size_ value mentioned + above. + +> If the program stores values for `$eip`, `$esp`, `$ebp`, `$ebx`, `$esi`, or +> `$edi`, then those are the values of the given registers in the caller. If the +> value of `$eip` is zero, that indicates that the end of the stack has been +> reached. + +The Breakpad processor checks that the value yielded by the above for the +calling frame's instruction address refers to known code; if the address seems +to be bogus, then it uses a heuristic search to find F's return address and +stack base. + +# `STACK CFI` records + +`STACK CFI` ("Call Frame Information") records describe how to walk the stack +when execution is at a given machine instruction. These records take one of two +forms: + +> `STACK CFI INIT` _address_ _size_ _register1_: +> _expression1_ _register2_: _expression2_ ... +> +> `STACK CFI` _address_ _register1_: _expression1_ +> _register2_: _expression2_ ... + +For example: + +``` +STACK CFI INIT 804c4b0 40 .cfa: $esp 4 + $eip: .cfa 4 - ^ +STACK CFI 804c4b1 .cfa: $esp 8 + $ebp: .cfa 8 - ^ +``` + +The _address_ and _size_ fields are hexadecimal numbers. Each +_register_i is the name of a register or pseudoregister. Each +_expression_ is a Breakpad postfix expression, which may contain spaces, but +never ends with a colon. (The appropriate register names for a given +architecture are determined when `STACK CFI` records are first enabled for that +architecture, and should be documented in the appropriate +`stackwalker_`_architecture_`.cc` source file.) + +STACK CFI records describe, at each machine instruction in a given function, how +to recover the values the machine registers had in the function's caller. +Naturally, some registers' values are simply lost, but there are three cases in +which they can be recovered: + +* You can always recover the program counter, because that's the function's + return address. If the function is ever going to return, the PC must be + saved somewhere. + +* You can always recover the stack pointer. The function is responsible for + popping its stack frame before it returns to the caller, so it must be able + to restore this, as well. + +* You should be able to recover the values of callee-saves registers. These + are registers whose values the callee must preserve, either by saving them + in its own stack frame before using them and re-loading them before + returning, or by not using them at all. + +(As an exception, note that functions which never return may not save any of +this data. It may not be possible to walk the stack past such functions' stack +frames.) + +Given rules for recovering the values of a function's caller's registers, we can +walk up the stack. Starting with the current set of registers --- the PC of the +instruction we're currently executing, the current stack pointer, etc. --- we +use CFI to recover the values those registers had in the caller of the current +frame. This gives us a PC in the caller whose CFI we can look up; we apply the +process again to find that function's caller; and so on. + +Concretely, CFI records represent a table with a row for each machine +instruction address and a column for each register. The table entry for a given +address and register contains a rule describing how, when the PC is at that +address, to restore the value that register had in the caller. + +There are some special columns: + +* A column named `.cfa`, for "Canonical Frame Address", tells how to compute + the base address of the frame; other entries can refer to the CFA in their + rules. + +* A column named `.ra` represents the return address. + +For example, suppose we have a machine with 32-bit registers, one-byte +instructions, a stack that grows downwards, and an assembly language that +resembles C. Suppose further that we have a function whose machine code looks +like this: + +``` +func: ; entry point; return address at sp +func+0: sp -= 16 ; allocate space for stack frame +func+1: sp[12] = r0 ; save 4-byte r0 at sp+12 + ... ; stuff that doesn't affect stack +func+10: sp -= 4; *sp = x ; push some 4-byte x on the stack + ... ; stuff that doesn't affect stack +func+20: r0 = sp[16] ; restore saved r0 +func+21: sp += 20 ; pop whole stack frame +func+22: pc = *sp; sp += 4 ; pop return address and jump to it +``` + +The following table would describe the function above: + +| **code address** | **.cfa** | **r0 (on Google Code)** | **r1 (on Google Code)** | ... | **.ra** | +|:-----------------|:---------|:------------------------|:------------------------|:----|:---------| +| func+0 | sp | | | | `cfa[0]` | +| func+1 | sp+16 | | | | `cfa[0]` | +| func+2 | sp+16 | `cfa[-4]` | | | `cfa[0]` | +| func+11 | sp+20 | `cfa[-4]` | | | `cfa[0]` | +| func+21 | sp+20 | | | | `cfa[0]` | +| func+22 | sp | | | | `cfa[0]` | + +Some things to note here: + +* Each row describes the state of affairs **before** executing the instruction + at the given address. Thus, the row for func+0 describes the state before we + execute the first instruction, which allocates the stack frame. In the next + row, the formula for computing the CFA has changed, reflecting the + allocation. + +* The other entries are written in terms of the CFA; this allows them to + remain unchanged as the stack pointer gets bumped around. For example, to + find the caller's value for r0 (on Google Code) at func+2, we would first + compute the CFA by adding 16 to the sp, and then subtract four from that to + find the address at which r0 (on Google Code) was saved. + +* Although the example doesn't show this, most calling conventions designate + "callee-saves" and "caller-saves" registers. The callee must restore the + values of "callee-saves" registers before returning (if it uses them at + all), whereas the callee is free to use "caller-saves" registers without + restoring their values. A function that uses caller-saves registers + typically does not save their original values at all; in this case, the CFI + marks such registers' values as "unrecoverable". + +* Exactly where the CFA points in the frame --- at the return address? below + it? At some fixed point within the frame? --- is a question of definition + that depends on the architecture and ABI in use. But by definition, the CFA + remains constant throughout the lifetime of the frame. It's up to + architecture- specific code to know what significance to assign the CFA, if + any. + +To save space, the most common type of CFI record only mentions the table +entries at which changes take place. So for the above, the CFI data would only +actually mention the non-blank entries here: + +| **insn** | **cfa** | **r0 (on Google Code)** | **r1 (on Google Code)** | ... | **ra** | +|:---------|:--------|:------------------------|:------------------------|:----|:---------| +| func+0 | sp | | | | `cfa[0]` | +| func+1 | sp+16 | | | | | +| func+2 | | `cfa[-4]` | | | | +| func+11 | sp+20 | | | | | +| func+21 | | r0 (on Google Code) | | | | +| func+22 | sp | | | | | + +A `STACK CFI INIT` record indicates that, at the machine instruction at +_address_, belonging to some function, the value that _registern_ had +in that function's caller can be recovered by evaluating +_expressionn_. The values of any callee-saves registers not mentioned +are assumed to be unchanged. (`STACK CFI` records never mention caller-saves +registers.) These rules apply starting at _address_ and continue up to, but not +including, the address given in the next `STACK CFI` record. The _size_ field is +the total number of bytes of machine code covered by this record and any +subsequent `STACK CFI` records (until the next `STACK CFI INIT` record). The +_address_ field is relative to the module's load address. + +A `STACK CFI` record (no `INIT`) is the same, except that it mentions only those +registers whose recovery rules have changed from the previous CFI record. There +must be a prior `STACK CFI INIT` or `STACK CFI` record in the symbol file. The +_address_ field of this record must be greater than that of the previous record, +and it must not be at or beyond the end of the range given by the most recent +`STACK CFI INIT` record. The address is relative to the module's load address. + +Each expression is a breakpad-style postfix expression. Expressions may contain +spaces, but their tokens may not end with colons. When an expression mentions a +register, it refers to the value of that register in the callee, even if a prior +name/expression pair gives that register's value in the caller. The exception is +`.cfa`, which refers to the canonical frame address computed by the .cfa rule in +force at the current instruction. + +The special expression `.undef` indicates that the given register's value cannot +be recovered. + +The register names preceding the expressions are always followed by colons. The +expressions themselves never contain tokens ending with colons. + +There are two special register names: + +* `.cfa` ("Canonical Frame Address") is the base address of the stack frame. + Other registers' rules may refer to this. If no rule is provided for the + stack pointer, the value of `.cfa` is the caller's stack pointer. + +* `.ra` is the return address. This is the value of the restored program + counter.

Header file. + +Several funtions are included here, forming a complete set of +conversions between the three formats. UTF-7 is not included +here, but is handled in a separate source file. + +Each of these routines takes pointers to input buffers and output +buffers. The input buffers are const. + +Each routine converts the text between *sourceStart and sourceEnd, +putting the result into the buffer between *targetStart and +targetEnd. Note: the end pointers are *after* the last item: e.g. +*(sourceEnd - 1) is the last item. + +The return result indicates whether the conversion was successful, +and if not, whether the problem was in the source or target buffers. +(Only the first encountered problem is indicated.) + +After the conversion, *sourceStart and *targetStart are both +updated to point to the end of last text successfully converted in +the respective buffers. + +Input parameters: +sourceStart - pointer to a pointer to the source buffer. +The contents of this are modified on return so that +it points at the next thing to be converted. +targetStart - similarly, pointer to pointer to the target buffer. +sourceEnd, targetEnd - respectively pointers to the ends of the +two buffers, for overflow checking only. + +These conversion functions take a ConversionFlags argument. When this +flag is set to strict, both irregular sequences and isolated surrogates +will cause an error. When the flag is set to lenient, both irregular +sequences and isolated surrogates are converted. + +Whether the flag is strict or lenient, all illegal sequences will cause +an error return. This includes sequences such as: , , +or in UTF-8, and values above 0x10FFFF in UTF-32. Conformant code +must check for illegal sequences. + +When the flag is set to lenient, characters over 0x10FFFF are converted +to the replacement character; otherwise (when the flag is set to strict) +they constitute an error. + +Output parameters: +The value "sourceIllegal" is returned from some routines if the input +sequence is malformed.

There are actually + // four axes(!) to the encoding: + // + // - The pointer size: pointers can be 2, 4, or 8 bytes long, or use + // the DWARF LEB128 encoding. + // + // - The pointer's signedness: pointers can be signed or unsigned. + // + // - The pointer's base address: the data stored in the exception + // handling data can be the actual address (that is, an absolute + // pointer), or relative to one of a number of different base + // addreses --- including that of the encoded pointer itself, for + // a form of "pc-relative" addressing. + // + // - The pointer may be indirect: it may be the address where the + // true pointer is stored. (This is used to refer to things via + // global offset table entries, program linkage table entries, or + // other tricks used in position-independent code.) + // + // There are also two options that fall outside that matrix + // altogether: the pointer may be omitted, or it may have padding to + // align it on an appropriate address boundary. (That last option + // may seem like it should be just another axis, but it is not.) + + // Indicate that the exception handling data is loaded starting at + // SECTION_BASE, and that the start of its buffer in our own memory + // is BUFFER_BASE.

It would be nice to be able to have separate +// handler classes for separate kinds of DIEs, each with the members +// appropriate to its role, instead of having one handler class that +// needs to hold data for every DIE type. +// +// - There should be a separate instance of the appropriate handler +// class for each DIE, instead of a single object with tables +// tracking all the dies in the compilation unit. +// +// - It's not convenient to take some action after all a DIE's +// attributes have been seen, but before visiting any of its +// children.

Thus: +// +// class My_DW_TAG_X_Handler: public DIEHandler { ... }; +// class My_DW_TAG_Y_Handler: public DIEHandler { ... }; +// +// DIEHandler subclasses needn't correspond exactly to single DIE +// types, as shown here; the point is that you can have several +// different classes appropriate to different kinds of DIEs. +// +// - In particular, define a handler class for the compilation +// unit's root DIE, that inherits from RootDIEHandler: +// +// class My_DW_TAG_compile_unit_Handler: public RootDIEHandler { ... }; +// +// RootDIEHandler inherits from DIEHandler, adding a few additional +// member functions for examining the compilation unit as a whole, +// and other quirks of rootness. +// +// - Then, create a DIEDispatcher instance, passing it an instance of +// your root DIE handler class, and use that DIEDispatcher as the +// dwarf2reader::CompilationUnit's handler: +// +// My_DW_TAG_compile_unit_Handler root_die_handler(...); +// DIEDispatcher die_dispatcher(&root_die_handler); +// CompilationUnit reader(sections, offset, bytereader, &die_dispatcher); +// +// Here, 'die_dispatcher' acts as a shim between 'reader' and the +// various DIE-specific handlers you have defined. +// +// - When you call reader.Start(), die_dispatcher behaves as follows, +// starting with your root die handler and the compilation unit's +// root DIE: +// +// - It calls the handler's ProcessAttributeX member functions for +// each of the DIE's attributes. +// +// - It calls the handler's EndAttributes member function.

If that +// returns a pointer to a DIEHandler instance, then +// die_dispatcher uses that handler to process the child, using +// this procedure recursively. Alternatively, if +// FindChildHandler returns NULL, die_dispatcher ignores that +// child and its descendants. +// +// - When die_dispatcher has finished processing all the DIE's +// children, it invokes the handler's Finish() member function, +// and destroys the handler. (As a special case, it doesn't +// destroy the root DIE handler.) +// +// This allows the code for handling a particular kind of DIE to be +// gathered together in a single class, makes it easy to skip all the +// children or individual children of a particular DIE, and provides +// appropriate parental context for each die. + +#ifndef COMMON_DWARF_DWARF2DIEHANDLER_H__ +#define COMMON_DWARF_DWARF2DIEHANDLER_H__ + +#include + +#include +#include + +#include "common/dwarf/types.h" +#include "common/dwarf/dwarf2enums.h" +#include "common/dwarf/dwarf2reader.h" +#include "common/using_std_string.h" + +namespace google_breakpad { + +// A base class for handlers for specific DIE types.

Thus, the row for func+0 +// describes the state before we allocate the stack frame. In the +// next row, the formula for computing the CFA has changed, +// reflecting that allocation. +// +// - The other entries are written in terms of the CFA; this allows +// them to remain unchanged as the stack pointer gets bumped around. +// For example, the rule for recovering the return address (the "ra" +// column) remains unchanged throughout the function, even as the +// stack pointer takes on three different offsets from the return +// address. +// +// - Although we haven't shown it, most calling conventions designate +// "callee-saves" and "caller-saves" registers. The callee must +// preserve the values of callee-saves registers; if it uses them, +// it must save their original values somewhere, and restore them +// before it returns. In contrast, the callee is free to trash +// caller-saves registers; if the callee uses these, it will +// probably not bother to save them anywhere, and the CFI will +// probably mark their values as "unrecoverable". +// +// (However, since the caller cannot assume the callee was going to +// save them, caller-saves registers are probably dead in the caller +// anyway, so compilers usually don't generate CFA for caller-saves +// registers.) +// +// - Exactly where the CFA points is a matter of convention that +// depends on the architecture and ABI in use. In the example, the +// CFA is the value the stack pointer had upon entry to the +// function, pointing at the saved return address. But on the x86, +// the call frame information generated by GCC follows the +// convention that the CFA is the address *after* the saved return +// address. +// +// But by definition, the CFA remains constant throughout the +// lifetime of the frame. This makes it a useful value for other +// columns to refer to. It is also gives debuggers a useful handle +// for identifying a frame. +// +// If you look at the table above, you'll notice that a given entry is +// often the same as the one immediately above it: most instructions +// change only one or two aspects of the stack frame, if they affect +// it at all. The DWARF format takes advantage of this fact, and +// reduces the size of the data by mentioning only the addresses and +// columns at which changes take place. So for the above, DWARF CFI +// data would only actually mention the following: +// +// insn cfa r0 r1 ... ra +// ======================================= +// func+0: sp cfa[0] +// func+1: sp+16 +// func+2: cfa[-4] +// func+11: sp+20 +// func+21: r0 +// func+22: sp +// +// In fact, this is the way the parser reports CFI to the consumer: as +// a series of statements of the form, "At address X, column Y changed +// to Z," and related conventions for describing the initial state. +// +// Naturally, it would be impractical to have to scan the entire +// program's CFI, noting changes as we go, just to recover the +// unwinding rules in effect at one particular instruction. To avoid +// this, CFI data is grouped into "entries", each of which covers a +// specified range of addresses and begins with a complete statement +// of the rules for all recoverable registers at that starting +// address. Each entry typically covers a single function. +// +// Thus, to compute the contents of a given row of the table --- that +// is, rules for recovering the CFA, RA, and registers at a given +// instruction --- the consumer should find the entry that covers that +// instruction's address, start with the initial state supplied at the +// beginning of the entry, and work forward until it has processed all +// the changes up to and including those for the present instruction. +// +// There are seven kinds of rules that can appear in an entry of the +// table: +// +// - "undefined": The given register is not preserved by the callee; +// its value cannot be recovered. +// +// - "same value": This register has the same value it did in the callee. +// +// - offset(N): The register is saved at offset N from the CFA. +// +// - val_offset(N): The value the register had in the caller is the +// CFA plus offset N. (This is usually only useful for describing +// the stack pointer.) +// +// - register(R): The register's value was saved in another register R. +// +// - expression(E): Evaluating the DWARF expression E using the +// current frame's registers' values yields the address at which the +// register was saved. +// +// - val_expression(E): Evaluating the DWARF expression E using the +// current frame's registers' values yields the value the register +// had in the caller. + +class CallFrameInfo { + public: + // The different kinds of entries one finds in CFI.

The 4 main abstractions used in this file are the +// following: +// +// * logger (GTMLogger) - The main logging class that users interact with. It +// has methods for logging at different levels and uses a log writer, a log +// formatter, and a log filter to get the job done. +// +// * log writer (GTMLogWriter) - Writes a given string to some log file, where +// a "log file" can be a physical file on disk, a POST over HTTP to some URL, +// or even some in-memory structure (e.g., a ring buffer). +// +// * log formatter (GTMLogFormatter) - Given a format string and arguments as +// a va_list, returns a single formatted NSString. A "formatted string" could +// be a string with the date prepended, a string with values in a CSV format, +// or even a string of XML. +// +// * log filter (GTMLogFilter) - Given a formatted log message as an NSString +// and the level at which the message is to be logged, this class will decide +// whether the given message should be logged or not. This is a flexible way +// to filter out messages logged at a certain level, messages that contain +// certain text, or filter nothing out at all. This gives the caller the +// flexibility to dynamically enable debug logging in Release builds. +// +// This file also declares some classes to handle the common log writer, log +// formatter, and log filter cases. Callers can also create their own writers, +// formatters, and filters and they can even build them on top of the ones +// declared here. Keep in mind that your custom writer/formatter/filter may be +// called from multiple threads, so it must be thread-safe. + +#import +#import "GTMDefines.h" + +// Predeclaration of used protocols that are declared later in this file. +@protocol GTMLogWriter, GTMLogFormatter, GTMLogFilter; + +// GTMLogger +// +// GTMLogger is the primary user-facing class for an object-oriented logging +// system. It is built on the concept of log formatters (GTMLogFormatter), log +// writers (GTMLogWriter), and log filters (GTMLogFilter). When a message is +// sent to a GTMLogger to log a message, the message is formatted using the log +// formatter, then the log filter is consulted to see if the message should be +// logged, and if so, the message is sent to the log writer to be written out. +// +// GTMLogger is intended to be a flexible and thread-safe logging solution. Its +// flexibility comes from the fact that GTMLogger instances can be customized +// with user defined formatters, filters, and writers. And these writers, +// filters, and formatters can be combined, stacked, and customized in arbitrary +// ways to suit the needs at hand. For example, multiple writers can be used at +// the same time, and a GTMLogger instance can even be used as another +// GTMLogger's writer. This allows for arbitrarily deep logging trees. +// +// A standard GTMLogger uses a writer that sends messages to standard out, a +// formatter that smacks a timestamp and a few other bits of interesting +// information on the message, and a filter that filters out debug messages from +// release builds. Using the standard log settings, a log message will look like +// the following: +// +// 2007-12-30 10:29:24.177 myapp[4588/0xa07d0f60] [lvl=1] foo= +// +// The output contains the date and time of the log message, the name of the +// process followed by its process ID/thread ID, the log level at which the +// message was logged (in the previous example the level was 1: +// kGTMLoggerLevelDebug), and finally, the user-specified log message itself (in +// this case, the log message was @"foo=%@", foo). +// +// Multiple instances of GTMLogger can be created, each configured their own +// way. Though GTMLogger is not a singleton (in the GoF sense), it does provide +// access to a shared (i.e., globally accessible) GTMLogger instance. This makes +// it convenient for all code in a process to use the same GTMLogger instance. +// The shared GTMLogger instance can also be configured in an arbitrary, and +// these configuration changes will affect all code that logs through the shared +// instance. + +// +// Log Levels +// ---------- +// GTMLogger has 3 different log levels: Debug, Info, and Error. GTMLogger +// doesn't take any special action based on the log level; it simply forwards +// this information on to formatters, filters, and writers, each of which may +// optionally take action based on the level. Since log level filtering is +// performed at runtime, log messages are typically not filtered out at compile +// time. The exception to this rule is that calls to the GTMLoggerDebug() macro +// *ARE* filtered out of non-DEBUG builds. This is to be backwards compatible +// with behavior that many developers are currently used to. Note that this +// means that GTMLoggerDebug(@"hi") will be compiled out of Release builds, but +// [[GTMLogger sharedLogger] logDebug:@"hi"] will NOT be compiled out. +// +// Standard loggers are created with the GTMLogLevelFilter log filter, which +// filters out certain log messages based on log level, and some other settings. +// +// In addition to the -logDebug:, -logInfo:, and -logError: methods defined on +// GTMLogger itself, there are also C macros that make usage of the shared +// GTMLogger instance very convenient. These macros are: +// +// GTMLoggerDebug(...) +// GTMLoggerInfo(...) +// GTMLoggerError(...) +// +// Again, a notable feature of these macros is that GTMLogDebug() calls *will be +// compiled out of non-DEBUG builds*. +// +// Standard Loggers +// ---------------- +// GTMLogger has the concept of "standard loggers". A standard logger is simply +// a logger that is pre-configured with some standard/common writer, formatter, +// and filter combination. Standard loggers are created using the creation +// methods beginning with "standard". The alternative to a standard logger is a +// regular logger, which will send messages to stdout, with no special +// formatting, and no filtering. +// +// How do I use GTMLogger? +// ---------------------- +// The typical way you will want to use GTMLogger is to simply use the +// GTMLogger*() macros for logging from code. That way we can easily make +// changes to the GTMLogger class and simply update the macros accordingly. Only +// your application startup code (perhaps, somewhere in main()) should use the +// GTMLogger class directly in order to configure the shared logger, which all +// of the code using the macros will be using. Again, this is just the typical +// situation. +// +// To be complete, there are cases where you may want to use GTMLogger directly, +// or even create separate GTMLogger instances for some reason. That's fine, +// too. +// +// Examples +// -------- +// The following show some common GTMLogger use cases. +// +// 1. You want to log something as simply as possible. Also, this call will only +// appear in debug builds. In non-DEBUG builds it will be completely removed. +// +// GTMLoggerDebug(@"foo = %@", foo); +// +// 2. The previous example is similar to the following. The major difference is +// that the previous call (example 1) will be compiled out of Release builds +// but this statement will not be compiled out. +// +// [[GTMLogger sharedLogger] logDebug:@"foo = %@", foo]; +// +// 3. Send all logging output from the shared logger to a file. We do this by +// creating an NSFileHandle for writing associated with a file, and setting +// that file handle as the logger's writer. +// +// NSFileHandle *f = [NSFileHandle fileHandleForWritingAtPath:@"/tmp/f.log" +// create:YES]; +// [[GTMLogger sharedLogger] setWriter:f]; +// GTMLoggerError(@"hi"); // This will be sent to /tmp/f.log +// +// 4. Create a new GTMLogger that will log to a file. This example differs from +// the previous one because here we create a new GTMLogger that is different +// from the shared logger. +// +// GTMLogger *logger = [GTMLogger standardLoggerWithPath:@"/tmp/temp.log"]; +// [logger logInfo:@"hi temp log file"]; +// +// 5. Create a logger that writes to stdout and does NOT do any formatting to +// the log message. This might be useful, for example, when writing a help +// screen for a command-line tool to standard output. +// +// GTMLogger *logger = [GTMLogger logger]; +// [logger logInfo:@"%@ version 0.1 usage", progName]; +// +// 6. Send log output to stdout AND to a log file. The trick here is that +// NSArrays function as composite log writers, which means when an array is +// set as the log writer, it forwards all logging messages to all of its +// contained GTMLogWriters. +// +// // Create array of GTMLogWriters +// NSArray *writers = [NSArray arrayWithObjects: +// [NSFileHandle fileHandleForWritingAtPath:@"/tmp/f.log" create:YES], +// [NSFileHandle fileHandleWithStandardOutput], nil]; +// +// GTMLogger *logger = [GTMLogger standardLogger]; +// [logger setWriter:writers]; +// [logger logInfo:@"hi"]; // Output goes to stdout and /tmp/f.log +// +// For futher details on log writers, formatters, and filters, see the +// documentation below. +// +// NOTE: GTMLogger is application level logging. By default it does nothing +// with _GTMDevLog/_GTMDevAssert (see GTMDefines.h). An application can choose +// to bridge _GTMDevLog/_GTMDevAssert to GTMLogger by providing macro +// definitions in its prefix header (see GTMDefines.h for how one would do +// that). +// +@interface GTMLogger : NSObject { + @private + id writer_; + id formatter_; + id filter_; +} + +// +// Accessors for the shared logger instance +// + +// Returns a shared/global standard GTMLogger instance.

This is the +// correct result. +// +// However, if we query DIA for the length and address of the symbol it will +// tell us that it has length 10 and is at RVA 0x00001000.

For a + * cleaner interface to these sizes when using C++, see minidump_size.h. + * + * These structures are also sufficient to populate minidump files. + * + * These definitions may be extended to support handling minidump files + * for other CPUs and other operating systems. + * + * Because precise data type sizes are crucial for this implementation to + * function properly and portably in terms of interoperability with minidumps + * produced by DbgHelp on Windows, a set of primitive types with known sizes + * are used as the basis of each structure defined by this file. DbgHelp + * on Windows is assumed to be the reference implementation; this file + * seeks to provide a cross-platform compatible implementation. To avoid + * collisions with the types and values defined and used by DbgHelp in the + * event that this implementation is used on Windows, each type and value + * defined here is given a new name, beginning with "MD". Names of the + * equivalent types and values in the Windows Platform SDK are given in + * comments. + * + * Author: Mark Mentovai */ + +#ifndef GOOGLE_BREAKPAD_COMMON_MINIDUMP_CPU_X86_H__ +#define GOOGLE_BREAKPAD_COMMON_MINIDUMP_CPU_X86_H__ + +#define MD_FLOATINGSAVEAREA_X86_REGISTERAREA_SIZE 80 + /* SIZE_OF_80387_REGISTERS */ + +typedef struct { + uint32_t control_word; + uint32_t status_word; + uint32_t tag_word; + uint32_t error_offset; + uint32_t error_selector; + uint32_t data_offset; + uint32_t data_selector; + + /* register_area contains eight 80-bit (x87 "long double") quantities for + * floating-point registers %st0 (%mm0) through %st7 (%mm7). */ + uint8_t register_area[MD_FLOATINGSAVEAREA_X86_REGISTERAREA_SIZE]; + uint32_t cr0_npx_state; +} MDFloatingSaveAreaX86; /* FLOATING_SAVE_AREA */ + + +#define MD_CONTEXT_X86_EXTENDED_REGISTERS_SIZE 512 + /* MAXIMUM_SUPPORTED_EXTENSION */ + +typedef struct { + /* The next field determines the layout of the structure, and which parts + * of it are populated */ + uint32_t context_flags; + + /* The next 6 registers are included with MD_CONTEXT_X86_DEBUG_REGISTERS */ + uint32_t dr0; + uint32_t dr1; + uint32_t dr2; + uint32_t dr3; + uint32_t dr6; + uint32_t dr7; + + /* The next field is included with MD_CONTEXT_X86_FLOATING_POINT */ + MDFloatingSaveAreaX86 float_save; + + /* The next 4 registers are included with MD_CONTEXT_X86_SEGMENTS */ + uint32_t gs; + uint32_t fs; + uint32_t es; + uint32_t ds; + /* The next 6 registers are included with MD_CONTEXT_X86_INTEGER */ + uint32_t edi; + uint32_t esi; + uint32_t ebx; + uint32_t edx; + uint32_t ecx; + uint32_t eax; + + /* The next 6 registers are included with MD_CONTEXT_X86_CONTROL */ + uint32_t ebp; + uint32_t eip; + uint32_t cs; /* WinNT.h says "must be sanitized" */ + uint32_t eflags; /* WinNT.h says "must be sanitized" */ + uint32_t esp; + uint32_t ss; + + /* The next field is included with MD_CONTEXT_X86_EXTENDED_REGISTERS. + * It contains vector (MMX/SSE) registers.

At the top level, a minidump file is represented by a +// Minidump object. Like most other classes in this module, Minidump +// provides a Read method that initializes the object with information from +// the file. Most of the classes in this file are wrappers around the +// "raw" structures found in the minidump file itself, and defined in +// minidump_format.h. For example, each thread is represented by a +// MinidumpThread object, whose parameters are specified in an MDRawThread +// structure. A properly byte-swapped MDRawThread can be obtained from a +// MinidumpThread easily by calling its thread() method. +// +// Most of the module lazily reads only the portion of the minidump file +// necessary to fulfill the user's request. Calling Minidump::Read +// only reads the minidump's directory. The thread list is not read until +// it is needed, and even once it's read, the memory regions for each +// thread's stack aren't read until they're needed. This strategy avoids +// unnecessary file input, and allocating memory for data in which the user +// has no interest. Note that although memory allocations for a typical +// minidump file are not particularly large, it is possible for legitimate +// minidumps to be sizable. A full-memory minidump, for example, contains +// a snapshot of the entire mapped memory space. Even a normal minidump, +// with stack memory only, can be large if, for example, the dump was +// generated in response to a crash that occurred due to an infinite- +// recursion bug that caused the stack's limits to be exceeded. Finally, +// some users of this library will unfortunately find themselves in the +// position of having to process potentially-hostile minidumps that might +// attempt to cause problems by forcing the minidump processor to over- +// allocate memory. +// +// Memory management in this module is based on a strict +// you-don't-own-anything policy. The only object owned by the user is +// the top-level Minidump object, the creation and destruction of which +// must be the user's own responsibility. All other objects obtained +// through interaction with this module are ultimately owned by the +// Minidump object, and will be freed upon the Minidump object's destruction. +// Because memory regions can potentially involve large allocations, a +// FreeMemory method is provided by MinidumpMemoryRegion, allowing the user +// to release data when it is no longer needed. Use of this method is +// optional but recommended. If freed data is later required, it will +// be read back in from the minidump file again. +// +// There is one exception to this memory management policy: +// Minidump::ReadString will return a string object to the user, and the user +// is responsible for its deletion. +// +// Author: Mark Mentovai + +#ifndef GOOGLE_BREAKPAD_PROCESSOR_MINIDUMP_H__ +#define GOOGLE_BREAKPAD_PROCESSOR_MINIDUMP_H__ + +#include + +#ifndef _WIN32 +#include +#endif + +#include +#include +#include +#include + +#include "common/basictypes.h" +#include "common/using_std_string.h" +#include "google_breakpad/processor/code_module.h" +#include "google_breakpad/processor/code_modules.h" +#include "google_breakpad/processor/dump_context.h" +#include "google_breakpad/processor/dump_object.h" +#include "google_breakpad/processor/memory_region.h" +#include "google_breakpad/processor/proc_maps_linux.h" + + +namespace google_breakpad { + + +using std::map; +using std::vector; + + +class Minidump; +template class RangeMap; + + +// MinidumpObject is the base of all Minidump* objects except for Minidump +// itself. +class MinidumpObject : public DumpObject { + public: + virtual ~MinidumpObject() {} + + protected: + explicit MinidumpObject(Minidump* minidump); + + // Refers to the Minidump object that is the ultimate parent of this + // Some MinidumpObjects are owned by other MinidumpObjects, but at the + // root of the ownership tree is always a Minidump.

Weird, yes, confusing, yes, welcome + * to the Intel ISA.

If this +// flag is empty, nothing happens here. If it contains a string, +// however, then HandleCommandLineCompletions() will hijack the +// process, attempting to identify the intention behind this +// completion. Regardless of the outcome of this deduction, the +// process will be terminated, similar to --helpshort flag +// handling. +// +// ** Overview of Bash completions: +// Bash can be told to programatically determine completions for the +// current 'cursor word'. It does this by (in this case) invoking a +// command with some additional arguments identifying the command +// being executed, the word being completed, and the previous word +// (if any). Bash then expects a sequence of output lines to be +// printed to stdout. If these lines all contain a common prefix +// longer than the cursor word, bash will replace the cursor word +// with that common prefix, and display nothing. If there isn't such +// a common prefix, bash will display the lines in pages using 'more'. +// +// ** Strategy taken for command line completions: +// If we can deduce either the exact flag intended, or a common flag +// prefix, we'll output exactly that. Otherwise, if information +// must be displayed to the user, we'll take the opportunity to add +// some helpful information beyond just the flag name (specifically, +// we'll include the default flag value and as much of the flag's +// description as can fit on a single terminal line width, as specified +// by the flag --tab_completion_columns). Furthermore, we'll try to +// make bash order the output such that the most useful or relevent +// flags are the most likely to be shown at the top. +// +// ** Additional features: +// To assist in finding that one really useful flag, substring matching +// was implemented. Before pressing a to get completion for the +// current word, you can append one or more '?' to the flag to do +// substring matching. Here's the semantics: +// --foo Show me all flags with names prefixed by 'foo' +// --foo? Show me all flags with 'foo' somewhere in the name +// --foo?? Same as prior case, but also search in module +// definition path for 'foo' +// --foo??? Same as prior case, but also search in flag +// descriptions for 'foo' +// Finally, we'll trim the output to a relatively small number of +// flags to keep bash quiet about the verbosity of output. If one +// really wanted to see all possible matches, appending a '+' to the +// search word will force the exhaustive list of matches to be printed. +// +// ** How to have bash accept completions from a binary: +// Bash requires that it be informed about each command that programmatic +// completion should be enabled for. Example addition to a .bashrc +// file would be (your path to gflags_completions.sh file may differ): + +/* +$ complete -o bashdefault -o default -o nospace -C \ + '/usr/local/bin/gflags_completions.sh --tab_completion_columns $COLUMNS' \ + time env binary_name another_binary [...] +*/ + +// This would allow the following to work: +// $ /path/to/binary_name --vmodule +// Or: +// $ ./bin/path/another_binary --gfs_u +// (etc) +// +// Sadly, it appears that bash gives no easy way to force this behavior for +// all commands. That's where the "time" in the above example comes in. +// If you haven't specifically added a command to the list of completion +// supported commands, you can still get completions by prefixing the +// entire command with "env". +// $ env /some/brand/new/binary --vmod +// Assuming that "binary" is a newly compiled binary, this should still +// produce the expected completion output. + + +#ifndef GOOGLE_GFLAGS_COMPLETIONS_H_ +#define GOOGLE_GFLAGS_COMPLETIONS_H_ + +namespace google { + +void HandleCommandLineCompletions(void); + +} + +#endif // GOOGLE_GFLAGS_COMPLETIONS_H_ diff --git a/shared/sentry/external/breakpad/src/third_party/mac_headers/README b/shared/sentry/external/breakpad/src/third_party/mac_headers/README new file mode 100644 index 000000000..c681bb3d6 --- /dev/null +++ b/shared/sentry/external/breakpad/src/third_party/mac_headers/README @@ -0,0 +1,2 @@ +These headers were copied from the Mac OS X 10.7 SDK to enable building +the Mac dump_syms code that processes Mach-O files on Linux. diff --git a/shared/sentry/external/breakpad/src/third_party/mac_headers/architecture/byte_order.h b/shared/sentry/external/breakpad/src/third_party/mac_headers/architecture/byte_order.h new file mode 100644 index 000000000..b772d9f38 --- /dev/null +++ b/shared/sentry/external/breakpad/src/third_party/mac_headers/architecture/byte_order.h @@ -0,0 +1,45 @@ +/* + * Copyright (c) 1999-2008 Apple Computer, Inc.

targetting the Linux syscall +API, suitable for use in a wide range of deployment environments. musl +offers efficient static and dynamic linking support, lightweight code +and low runtime overhead, strong fail-safe guarantees under correct +usage, and correctness in the sense of standards conformance and +safety. musl is built on the principle that these goals are best +achieved through simple code that is easy to understand and maintain. + +The 1.1 release series for musl features coverage for all interfaces +defined in ISO C99 and POSIX 2008 base, along with a number of +non-standardized interfaces for compatibility with Linux, BSD, and +glibc functionality. + +For basic installation instructions, see the included INSTALL file. +Information on full musl-targeted compiler toolchains, system +bootstrapping, and Linux distributions built on musl can be found on +the project website: + + http://www.musl-libc.org/ diff --git

This method directs crashes to the Crashpad handler. On macOS, this is + //! applicable to this process and all subsequent child processes. On Windows, + //! child processes must also register by using SetHandlerIPCPipe(). + //! + //! On macOS, this method starts a Crashpad handler and obtains a Mach send + //! right corresponding to a receive right held by the handler process. The + //! handler process runs an exception server on this port. This method sets + //! the task’s exception port for `EXC_CRASH`, `EXC_RESOURCE`, and `EXC_GUARD` + //! exceptions to the Mach send right obtained. The handler will be installed + //! with behavior `EXCEPTION_STATE_IDENTITY | MACH_EXCEPTION_CODES` and thread + //! state flavor `MACHINE_THREAD_STATE`. Exception ports are inherited, so a + //! Crashpad handler started here will remain the handler for any child + //! processes created after StartHandler() is called. These child processes do + //! not need to call StartHandler() or be aware of Crashpad in any way. The + //! Crashpad handler will receive crashes from child processes that have + //! inherited it as their exception handler even after the process that called + //! StartHandler() exits. + //! + //! On Windows, if \a asynchronous_start is `true`, this function will not + //! directly call `CreateProcess()`, making it suitable for use in a + //! `DllMain()`. In that case, the handler is started from a background + //! thread, deferring the handler's startup. Nevertheless, regardless of the + //! value of \a asynchronous_start, after calling this method, the global + //! unhandled exception filter is set up, and all crashes will be handled by + //! Crashpad. Optionally, use WaitForHandlerStart() to join with the + //! background thread and retrieve the status of handler startup. + //! + //! On Fuchsia, this method binds to the exception port of the current default + //! job, and starts a Crashpad handler to monitor that port. + //! + //! On Linux, this method starts a Crashpad handler, connected to this process + //! via an `AF_UNIX` socket pair and installs signal handlers to request crash + //! dumps on the client's socket end. + //! + //! \param[in] handler The path to a Crashpad handler executable. + //! \param[in] database The path to a Crashpad database.

Most of its +development practices follow Chromium’s. In order to function on its own in +other projects, Crashpad uses +[mini_chromium](https://chromium.googlesource.com/chromium/mini_chromium/), a +small, self-contained library that provides many of Chromium’s useful low-level +base routines. [mini_chromium’s +README](https://chromium.googlesource.com/chromium/mini_chromium/+/master/README.md) +provides more detail. + +## Prerequisites + +To develop Crashpad, the following tools are necessary, and must be present in +the `$PATH` environment variable: + + * Appropriate development tools. + * On macOS, install [Xcode](https://developer.apple.com/xcode/). The latest + version is generally recommended. + * On Windows, install [Visual Studio](https://www.visualstudio.com/) with + C++ support and the Windows SDK. The latest version is generally + recommended. Some tests also require the CDB debugger, installed with + [Debugging Tools for + Windows](https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/). + * On Linux, obtain appropriate tools for C++ development through any + appropriate means including the system’s package manager. On Debian and + Debian-based distributions, the `build-essential`, `zlib1g-dev`, and any + one of the `libcurl4-*-dev` packages such as `libcurl4-openssl-dev` should + suffice. + * Chromium’s + [depot_tools](https://www.chromium.org/developers/how-tos/depottools). + * [Git](https://git-scm.com/). This is provided by Xcode on macOS, by + depot_tools on Windows, and through any appropriate means including the + system’s package manager on Linux. + * [Python](https://www.python.org/). This is provided by the operating system + on macOS, by depot_tools on Windows, and through any appropriate means + including the system’s package manager on Linux. + +## Getting the Source Code + +The main source code repository is a Git repository hosted at +https://chromium.googlesource.com/crashpad/crashpad. Although it is possible to +check out this repository directly with `git clone`, Crashpad’s dependencies are +managed by +[`gclient`](https://www.chromium.org/developers/how-tos/depottools#TOC-gclient) +instead of Git submodules, so to work on Crashpad, it is best to use `fetch` to +get the source code. + +`fetch` and `gclient` are part of the +[depot_tools](https://www.chromium.org/developers/how-tos/depottools). There’s +no need to install them separately. + +### Initial Checkout + +``` +$ mkdir ~/crashpad +$ cd ~/crashpad +$ fetch crashpad +``` + +`fetch crashpad` performs the initial `git clone` and `gclient sync`, +establishing a fully-functional local checkout. + +### Subsequent Checkouts + +``` +$ cd ~/crashpad/crashpad +$ git pull -r +$ gclient sync +``` + +## Building + +### Windows, Mac, Linux, Fuchsia + +On Windows, Mac, Linux, and Fuchsia, Crashpad uses +[GN](https://gn.googlesource.com/gn) to generate +[Ninja](https://ninja-build.org/) build files. For example, + +``` +$ cd ~/crashpad/crashpad +$ gn gen out/Default +$ ninja -C out/Default +``` + +You can then use `gn args out/Default` or edit `out/Default/args.gn` to +configure the build, for example things like `is_debug=true` or +`target_cpu="x86"`. + +GN and Ninja are part of the +[depot_tools](https://www.chromium.org/developers/how-tos/depottools). There’s +no need to install them separately. + +#### Fuchsia + +In order to instruct gclient to download the Fuchsia SDK, you need to add the +following to `~/crashpad/.gclient`: + +``` +target_os=["fuchsia"] +``` + +If you're using this tree to develop for multiple targets, you can also add +other entries to the the list (e.g. `target_os=["fuchsia", "mac"]`). + +#### Optional Linux Configs + +To pull and use Crashpad's version of clang and sysroot, make the following +changes. + +Add the following to `~/crashpad/.gclient`. +``` +"custom_vars": { "pull_linux_clang": True }, +``` +Add these args to `out/Default/args.gn`. +``` +clang_path = "//third_party/linux/clang/linux-amd64" +target_sysroot = "//third_party/linux/sysroot" +``` + +### Android + +This build relies on cross-compilation. It’s possible to develop Crashpad for +Android on any platform that the [Android NDK (Native Development +Kit)](https://developer.android.com/ndk/) runs on. + +If it’s not already present on your system, [download the NDK package for your +system](https://developer.android.com/ndk/downloads/) and expand it to a +suitable location. These instructions assume that it’s been expanded to +`~/android-ndk-r21b`. + +Note that Chrome uses Android API level 21 for both 64-bit platforms and +32-bit platforms. See Chrome’s +[`build/config/android/config.gni`](https://chromium.googlesource.com/chromium/src/+/master/build/config/android/config.gni) +which sets `android32_ndk_api_level` and `android64_ndk_api_level`. + +Set these gn args +``` +target_os = "android" +android_ndk_root = ~/android-ndk-r21b +android_api_level = 21 +``` + +## Testing + +Crashpad uses [Google Test](https://github.com/google/googletest/) as its +unit-testing framework, and some tests use [Google +Mock](https://github.com/google/googletest/tree/master/googlemock/) as well. Its +tests are currently split up into several test executables, each dedicated to +testing a different component. This may change in the future. After a successful +build, the test executables will be found at `out/Debug/crashpad_*_test`. + +``` +$ cd ~/crashpad/crashpad +$ out/Debug/crashpad_minidump_test +$ out/Debug/crashpad_util_test +``` + +A script is provided to run all of Crashpad’s tests. It accepts a single +argument, a path to the directory containing the test executables. + +``` +$ cd ~/crashpad/crashpad +$ python build/run_tests.py out/Debug +``` + +To run a subset of the tests, use the `--gtest_filter` flag, e.g., to run all +the tests for MinidumpStringWriter: + +``` +$ python build/run_tests.py out/Debug --gtest_filter MinidumpStringWriter\* +``` + +### Windows + +On Windows, `end_to_end_test.py` requires the CDB debugger, installed with +[Debugging Tools for +Windows](https://docs.microsoft.com/windows-hardware/drivers/debugger/). This +can be installed either as part of the [Windows Driver +Kit](https://docs.microsoft.com/windows-hardware/drivers/download-the-wdk) or +the [Windows +SDK](https://developer.microsoft.com/windows/downloads/windows-10-sdk/). If the +Windows SDK has already been installed (possibly with Visual Studio) but +Debugging Tools for Windows is not present, it can be installed from Add or +remove programs→Windows Software Development Kit. + +### Android + +To test on Android, [ADB (Android Debug +Bridge)](https://developer.android.com/studio/command-line/adb.html) from the +[Android SDK](https://developer.android.com/sdk/) must be in the `PATH`. Note +that it is sufficient to install just the command-line tools from the Android +SDK. The entire Android Studio IDE is not necessary to obtain ADB. + +When asked to test an Android build directory, `run_tests.py` will detect a +single connected Android device (including an emulator). If multiple devices are +connected, one may be chosen explicitly with the `ANDROID_DEVICE` environment +variable. `run_tests.py` will upload test executables and data to a temporary +location on the detected or selected device, run them, and clean up after itself +when done. + +### Fuchsia + +To test on Fuchsia, you need a connected device running Fuchsia. Run: + +``` +$ gn gen out/fuchsia --args 'target_os="fuchsia" target_cpu="x64" is_debug=true' +$ ninja -C out/fuchsia +$ python build/run_tests.py out/fuchsia +``` + +If you have multiple devices running, you will need to specify which device you +want using their hostname, for instance: + +``` +$ ZIRCON_NODENAME=scare-brook-skip-dried python build/run_tests.py out/fuchsia +``` + +## Contributing + +Crashpad’s contribution process is very similar to [Chromium’s contribution +process](https://chromium.googlesource.com/chromium/src/+/master/docs/contributing.md). + +### Code Review + +A code review must be conducted for every change to Crashpad’s source code. Code +review is conducted on [Chromium’s +Gerrit](https://chromium-review.googlesource.com/) system, and all code reviews +must be sent to an appropriate reviewer, with a Cc sent to +[crashpad-dev](https://groups.google.com/a/chromium.org/group/crashpad-dev). The +[`codereview.settings`](https://chromium.googlesource.com/crashpad/crashpad/+/master/codereview.settings) +file specifies this environment to `git-cl`. + +`git-cl` is part of the +[depot_tools](https://www.chromium.org/developers/how-tos/depottools). There’s +no need to install it separately. + +``` +$ cd ~/crashpad/crashpad +$ git checkout -b work_branch origin/master +…do some work… +$ git add … +$ git commit +$ git cl upload +``` + +Uploading a patch to Gerrit does not automatically request a review. You must +select a reviewer on the Gerrit review page after running `git cl upload`. This +action notifies your reviewer of the code review request. If you have lost track +of the review page, `git cl issue` will remind you of its URL. Alternatively, +you can request review when uploading to Gerrit by using `git cl upload +--send-mail`. + +Git branches maintain their association with Gerrit reviews, so if you need to +make changes based on review feedback, you can do so on the correct Git branch, +committing your changes locally with `git commit`. You can then upload a new +patch set with `git cl upload` and let your reviewer know you’ve addressed the +feedback. + +The most recently uploaded patch set on a review may be tested on a +[trybot](https://chromium.googlesource.com/chromium/src/+/master/docs/infra/trybot_usage.md) +by running `git cl try` or by clicking the “CQ Dry Runâ€Â button in Gerrit.

The iOS sandbox, +however, restricts applications from delegating work to separate processes. +This limitation means Crashpad on iOS must combine the work of the handler and +the client into the same process as the main application. + +## The Crashpad In-Process Handler + +In-process handling comes with a number of limitations and difficulties. It is +not possible to catch the specific Mach exception `EXC_CRASH`, so certain groups +of crashes cannot be captured. This includes some major ones, like out-of-memory +crashes. This also introduces difficulties in capturing all the relevant crash +data and writing the minidump, as the process itself is in an unsafe state. + +While handling an exception, the handler may not, for example: + + - Allocate memory. + - Use libc, or most any library call. + +While handling an exception, the handler may only: + + - Use audited syscalls. + - access memory via `vm_read`. + +In conjunction with Crashpad’s existing minidump writer and structural +limitations of the minidump format, it is not possible to write a minidump +immediately from the crash handler. Instead, an intermediate dump is written +when a handler would normally write a minidump (such as during an exception or a +forced dump without crashing). The intermediate dump file will be converted to +a minidump on the next run (or when the application decides it's safe to do so). + +During Crashpad initialization, the handler gathers basic system information +and opens a pending intermediate dump adjacent to the Crashpad database. + +## The Crashpad IntermediateDump Format + +Due to the limitations of in-process handling, an intermediate dump file is +written during exceptions. The data is streamed to a file, which will be used to +generate a final minidump when appropriate. + +The file format is similar to binary JSON, supporting keyed properties, maps and +arrays. + + - `Property` [key:int, length:int, value:intarray] + - `StartMap` [key:int], followed by repeating Properties until `EndMap` + - `StartArray` [key:int], followed by repeating Maps until `EndArray` + - `EndMap`, `EndArray`, `EndDocument` + +Similar to JSON, maps can contain other maps, arrays and properties. + +## The life of an iOS crash report + +Immediately upon calling StartCrashpadInProcessHandler, the iOS in-process +handler is installed. This will open a temporary file within the database +directory, in a subdirectory named `pending-serialized-ios-dump`. This file will +be used to write an intermediate dump in the event of a crash. This must happen +before installing the various types of crash handlers, as each depends on having +a valid handler with an intermediate dump ready to be written to. + +After the in-process handler is initialized, the Mach exception, POSIX signal +and Objective-C exception preprocessor handlers are installed. + +### Intermediate Dump File Locking + +It is expected that multiple Crashpad clients may share the same database +directory, and this directory may be inside an iOS app group directory. While +it's possible for each Crashpad client to write to its own private directory, +if a shared directory is used, it's possible for different applications to +upload a crash report from any application in a shared group. This might be +used, for example, by an application and its various app extensions, where each +client may generate a crash report but only the main application uploads +reports. Alternatively, a suite of applications may upload each other's crash +reports. Otherwise, the only opportunity to upload a report would be when a +specific app that crashed relaunches. + +To prevent multiple clients from processing a pending intermediate dump, files +must be locked. However, POSIX locks on app group files will trigger app +termination on app backgrounding, so a custom file locking protocol is used. +Locked temporary files are named `@.locked`. The `.locked` +extension is removed when the file is unlocked. The `bundle-id` is used to +determine which Crashpad clients can process leftover locked files. + +### Writing Crashes to Intermediate Dumps + +When an app encounters a crash (via a Mach exception, Objective-C exception, or +a POSIX signal), an intermediate dump is written to the temporary locked file, +the .locked extension is removed, and a new temporary locked file is opened. + +App terminations not handled by Crashpad will leave behind a temporary +locked file, to be cleaned up on next launch. These files are still processed, +because it is possible for the app to be terminated while writing an +intermediate dump, and if enough data is written this may still be valuable. + +Note: Generally iOS apps are single-process, so it's safe for the client to +consider any files matching its `bundle-id`, but there are edge-cases (such as +if a share-to app extension is opened at the same time in two different apps) so +old locked files won't be cleared until after 24 hours. Any locked file found +after 60 days is unlocked regardless of `bundle-id`. + +### Writing to Intermediate Dumps without a Crash + +Apps may also generate intermediate dumps without a crash, often used for +debugging. Chromium makes heavy use of this for detecting main thread hangs, +something that can appear as a crash for the user, but is uncatchable for crash +handlers like Crashpad. When an app requests this (via DumpWithoutCrash, +DumpWithoutCrashAndDeferProcessing), an intermediate dump is written to the +temporary locked file, the .locked extension is removed, and a new temporary +locked file is opened. + +Note: DumpWithoutCrashAndDeferProcessingAtPath writes an intermediate dump to +the requested location, not the previously opened temporary file. This is useful +because Chromium's main thread hang detection will throw away hang reports in +certain circumstances (if the app recovers, if a different crash report is +written, etc). + +## The Crashpad In-Process Client + +Other Crashpad platforms handle exceptions and upload minidumps out-of-process. +On iOS, everything must happen in-process. Once started, the client will +automatically handle exceptions and capture the crashed process state in an +intermediate dump file. Converting that intermediate dump file into a minidump +is likely not safe to do from within a crashed process, and uploading a minidump +is definitely unsafe to do at crash time. Applications are expected to process +intermediate dumps into pending minidumps and begin processing pending +minidumps, possibly for upload, at suitable times following the next application +restart. + +Note: Applications are not required to call either of these methods. For +example, application extensions may choose to generate dumps but leave +processing and uploading to the main applications. Clients that share the +same database directory between apps can take advantage of processing and +uploading crash reports from different applications. + +### `ProcessIntermediateDumps` +For performance and stability reasons applications may choose the correct time +to convert intermediate dumps, as well as append metadata to the pending +intermediate dumps. This is expected to happen during application startup, when +suitable. After converting, a minidump will be written to the Crashpad database, +similar to how other platforms write a minidump on exception handling. If +uploading is enabled, this minidump will also be immediately uploaded. New +intermediate dumps generated by exceptions or by +`CRASHPAD_SIMULATE_CRASH_AND_DEFER_PROCESSING` will not be processed until +the next call to `ProcessIntermediateDumps`. Conversely, +`CRASHPAD_SIMULATE_CRASH` can be called when the client has no performance or +stability concerns. In this case, intermediate dumps are automatically +converted to minidumps and immediately eligible for uploading. + +Applications can include annotations here as well. Chromium uses this for its +insta-crash logic, which detects if an app is crashing repeatedly on startup. + +### `StartProcessingPendingReports` +For similar reasons, applications may choose the correct time to begin uploading +pending reports, such as when ideal network conditions exist. By default, +clients start with uploading disabled. Applications should call this API when +it is determined that it is appropriate to do so (such as on a few seconds after +startup, or when network connectivity is appropriate). diff --git

capturing, storing and transmitting postmortem crash +reports from a client to an upstream collection server. Crashpad aims to make it +possible for clients to capture process state at the time of crash with the best +possible fidelity and coverage, with the minimum of fuss. + +Crashpad also provides a facility for clients to capture dumps of process state +on-demand for diagnostic purposes. + +Crashpad additionally provides minimal facilities for clients to adorn their +crashes with application-specific metadata in the form of per-process key/value +pairs. More sophisticated clients are able to adorn crash reports further +through extensibility points that allow the embedder to augment the crash report +with application-specific metadata. + +## Background + +It’s an unfortunate truth that any large piece of software will contain bugs +that will cause it to occasionally crash. Even in the absence of bugs, software +incompatibilities can cause program instability. + +Fixing bugs and incompatibilities in client software that ships to millions of +users around the world is a daunting task. User reports and manual reproduction +of crashes can work, but even given a user report, often times the problem is +not readily reproducible. This is for various reasons, such as e.g. system +version or third-party software incompatibility, or the problem can happen due +to a race of some sort. Users are also unlikely to report problems they +encounter, and user reports are often of poor quality, as unfortunately most +users don’t have experience with making good bug reports. + +Automatic crash telemetry has been the best solution to the problem so far, as +this relieves the burden of manual reporting from users, while capturing the +hardware and software state at the time of crash. + +TODO(siggi): examples of this? + +Crash telemetry involves capturing postmortem crash dumps and transmitting them +to a backend collection server. On the server they can be stackwalked and +symbolized, and evaluated and aggregated in various ways. Stackwalking and +symbolizing the reports on an upstream server has several benefits over +performing these tasks on the client. High-fidelity stackwalking requires access +to bulky unwind data, and it may be desirable to not ship this to end users out +of concern for the application size. The process of symbolization requires +access to debugging symbols, which can be quite large, and the symbolization +process can consume considerable other resources. Transmitting un-stackwalked +and un-symbolized postmortem dumps to the collection server also allows deep +analysis of individual dumps, which is often necessary to resolve the bug +causing the crash. + +Transmitting reports to the collection server allows aggregating crashes by +cause, which in turn allows assessing the importance of different crashes in +terms of the occurrence rate and e.g. the potential security impact. + +A postmortem crash dump must contain the program state at the time of crash +with sufficient fidelity to allow diagnosing and fixing the problem. As the full +program state is usually too large to transmit to an upstream server, the +postmortem dump captures a heuristic subset of the full state. + +The crashed program is in an indeterminate state and, in fact, has often crashed +because of corrupt global state - such as heap. It’s therefore important to +generate crash reports with as little execution in the crashed process as +possible. Different operating systems vary in the facilities they provide for +this. + +## Overview + +Crashpad is a client-side library that focuses on capturing machine and program +state in a postmortem crash report, and transmitting this report to a backend +server - a “collection serverâ€. The Crashpad library is embedded by the client +application. Conceptually, Crashpad breaks down into the handler and the client. +The handler runs in a separate process from the client or clients. It is +responsible for snapshotting the crashing client process’ state on a crash, +saving it to a crash dump, and transmitting the crash dump to an upstream +server. Clients register with the handler to allow it to capture and upload +their crashes. On iOS, there is no separate process for the handler. +[This is a limitation of iOS.](ios_overview_design.md#ios-limitations) + +### The Crashpad handler + +The Crashpad handler is instantiated in a process supplied by the embedding +application. It provides means for clients to register themselves by some means +of IPC, or where operating system support is available, by taking advantage of +such support to cause crash notifications to be delivered to the handler. On +crash, the handler snapshots the crashed client process’ state, writes it to a +postmortem dump in a database, and may also transmit the dump to an upstream +server if so configured. + +The Crashpad handler is able to handle cross-bitted requests and generate crash +dumps across bitness, where e.g. the handler is a 64-bit process while the +client is a 32-bit process or vice versa. In the case of Windows, this is +limited by the OS such that a 32-bit handler can only generate crash dumps for +32-bit clients, but a 64-bit handler can acquire nearly all of the detail for a +32-bit process. + +### The Crashpad client + +The Crashpad client provides two main facilities. +1. Registration with the Crashpad handler. +2. Metadata communication to the Crashpad handler on crash. + +A Crashpad embedder links the Crashpad client library into one or more +executables, whether a loadable library or a program file. The client process +then registers with the Crashpad handler through some mode of IPC or other +operating system-specific support. + +On crash, metadata is communicated to the Crashpad handler via the CrashpadInfo +structure. Each client executable module linking the Crashpad client library +embeds a CrashpadInfo structure, which can be updated by the client with +whatever state the client wishes to record with a crash. + +![Overview image](overview.png) + +Here is an overview picture of the conceptual relationships between embedder (in +light blue), client modules (darker blue), and Crashpad (in green). Note that +multiple client modules can contain a CrashpadInfo structure, but only one +registration is necessary. + +## Detailed Design + +### Requirements + +The purpose of Crashpad is to capture machine, OS and application state in +sufficient detail and fidelity to allow developers to diagnose and, where +possible, fix the issue causing the crash. + +Each distinct crash report is assigned a globally unique ID, in order to allow +users to associate them with a user report, report in bug reports and so on. + +It’s critical to safeguard the user’s privacy by ensuring that no crash report +is ever uploaded without user consent. Likewise it’s important to ensure that +Crashpad never captures or uploads reports from non-client processes. + +### Concepts + +* **Client ID**. A UUID tied to a single instance of a Crashpad database. When + creating a crash report, the Crashpad handler includes the client ID stored + in the database. This provides a means to determine how many individual end + users are affected by a specific crash signature. + +* **Crash ID**. A UUID representing a single crash report. Uploaded crash + reports also receive a “server ID.†The Crashpad database indexes both the + locally-generated and server-generated IDs. + +* **Collection Server**. See [crash server documentation.]( + https://goto.google.com/crash-server-overview) + +* **Client Process**. Any process that has registered with a Crashpad handler. + +* **Handler process**. A process hosting the Crashpad handler library. This may + be a dedicated executable, or it may be hosted within a client executable + with control passed to it based on special signaling under the client’s + control, such as a command-line parameter. + +* **CrashpadInfo**. A structure used by client modules to provide information to + the handler. + +* **Annotations**. Each CrashpadInfo structure points to a dictionary of + {string, string} annotations that the client can use to communicate + application state in the case of crash. + +* **Database**. The Crashpad database contains persistent client settings as + well as crash dumps pending upload. + +TODO(siggi): moar concepts? + +### Overview Picture + +Here is a rough overview picture of the various Crashpad constructs, their +layering and intended use by clients. + +![Layering image](layering.png) + +Dark blue boxes are interfaces, light blue boxes are implementation. Gray is the +embedding client application. Note that wherever possible, implementation that +necessarily has to be OS-specific, exposes OS-agnostic interfaces to the rest of +Crashpad and the client. + +### Registration + +The particulars of how a client registers with the handler varies across +operating systems. + +#### macOS + +At registration time, the client designates a Mach port monitored by the +Crashpad handler as the EXC_CRASH exception port for the client. The port may be +acquired by launching a new handler process or by retrieving service already +registered with the system. The registration is maintained by the kernel and is +inherited by subprocesses at creation time by default, so only the topmost +process of a process tree need register. + +Crashpad provides a facility for a process to disassociate (unregister) with an +existing crash handler, which can be necessary when an older client spawns an +updated version. + +#### iOS + +iOS registers both a signal handler for `SIGABRT` and a Mach exception handler +with a subset of available exceptions. [This is a limitation of +iOS.](ios_overview_design.md#ios-limitations) + +#### Windows + +There are two modes of registration on Windows. In both cases the handler is +advised of the address of a set of structures in the client process’ address +space. These structures include a pair of ExceptionInformation structs, one for +generating a postmortem dump for a crashing process, and another one for +generating a dump for a non- crashing process. + +##### Normal registration + +In the normal registration mode, the client connects to a named pipe by a +pre-arranged name. A registration request is written to the pipe. During +registration, the handler creates a set of events, duplicates them to the +registering client, then returns the handle values in the registration response. +This is a blocking process. + +##### Initial Handler Creation + +In order to avoid blocking client startup for the creation and initialization of +the handler, a different mode of registration can be used for the handler +creation. In this mode, the client creates a set of event handles and inherits +them into the newly created handler process. The handler process is advised of +the handle values and the location of the ExceptionInformation structures by way +of command line arguments in this mode. + +#### Linux/Android + +On Linux, a registration is a connected socket pair between a client process and +the Crashpad handler. This socket pair may be private or shared among many +client processes. + +##### Private Connections + +Private connections are the default registration mode when starting the handler +process in response to a crash or on behalf of another client. This mode is +required to use a ptrace broker, which is in turn required to trace Android +isolated processes. + +##### Shared Connections + +Shared connections are the default mode when using a long-lived handler. The +same connected socket pair may be shared among any number of clients. The socket +pair is created by the first process to start the handler at which point the +client socket end may be shared with other clients by any convenient means (e.g. +inheritance). + +### Capturing Exceptions + +The details of how Crashpad captures the exceptions leading to crashes varies +between operating systems. + +#### macOS + +On macOS, the operating system will notify the handler of client crashes via the +Mach port set as the client process’ exception port. As exceptions are +dispatched to the Mach port by the kernel, on macOS, exceptions can be handled +entirely from the Crashpad handler without the need to run any code in the crash +process at the time of the exception. + +#### iOS + +On iOS, the operating system will notify the handler of crashes via the Mach +exception port or the signal handler. As exceptions are handled in-process, an +intermediate dump file is generated rather than a minidump. See more +information about the [iOS in-process +handler.](ios_overview_design.md#ios-in-process-handler) + +#### Windows + +On Windows, the OS dispatches exceptions in the context of the crashing thread. +To notify the handler of exceptions, the Crashpad client registers an +UnhandledExceptionFilter (UEF) in the client process. When an exception trickles +up to the UEF, it stores the exception information and the crashing thread’s ID +in the ExceptionInformation structure registered with the handler. It then sets +an event handle to signal the handler to go ahead and process the exception. + +##### Caveats + +* If the crashing thread’s stack is smashed when an exception occurs, the + exception cannot be dispatched. In this case the OS will summarily terminate + the process, without the handler having an opportunity to generate a crash + report. +* If an exception is handled in the crashing thread, it will never propagate + to the UEF, and thus a crash report won’t be generated. This happens a fair + bit in Windows as system libraries will often dispatch callbacks under a + structured exception handler. This occurs during Window message dispatching + on some system configurations, as well as during e.g. DLL entry point + notifications. +* A growing number of conditions in the system and runtime exist where + detected corruption or illegal calls result in summary termination of the + process, in which case no crash report will be generated. + +###### Out-Of-Process Exception Handling + +There exists a mechanism in Windows Error Reporting (WER) that allows a client +process to register for handling client exceptions out of the crashing process. +Unfortunately this mechanism is difficult to use, and doesn’t provide coverage +for many of the caveats above. [Details +here.](https://crashpad.chromium.org/bug/133) + +#### Linux/Android + +On Linux, exceptions are dispatched as signals to the crashing thread. Crashpad +signal handlers will send a message over the socket to the Crashpad handler +notifying it of the crash and the location of exception information to be read +from the crashing process. When using a shared socket connection, communication +is entirely one-way. The client sends its dump request to the handler and then +waits until the handler responds with a SIGCONT or a timeout occurs. When using +a private socket connection, the handler may respond over the socket to +communicate with a ptrace broker process. The broker is forked from the crashing +process, executes ptrace requests against the crashing process, and sends the +information over the socket to the handler. + +### The CrashpadInfo structure + +The CrashpadInfo structure is used to communicate information from the client to +the handler. Each executable module in a client process can contain a +CrashpadInfo structure. On a crash, the handler crawls all modules in the +crashing process to locate all CrashpadInfo structures present. The CrashpadInfo +structures are linked into a special, named section of the executable, where the +handler can readily find them. + +The CrashpadInfo structure has a magic signature, and contains a size and a +version field. The intent is to allow backwards compatibility from older client +modules to newer handler. It may also be necessary to provide forwards +compatibility from newer clients to older handler, though this hasn’t occurred +yet. + +The CrashpadInfo structure contains such properties as the cap for how much +memory to include in the crash dump, some tristate flags for controlling the +handler’s behavior, a pointer to an annotation dictionary and so on. + +### Snapshot + +Snapshot is a layer of interfaces that represent the machine and OS entities +that Crashpad cares about. Different concrete implementations of snapshot can +then be backed different ways, such as e.g. from the in-memory representation of +a crashed process, or e.g. from the contents of a minidump. + +### Crash Dump Creation + +To create a crash dump, a subset of the machine, OS and application state is +grabbed from the crashed process into an in-memory snapshot structure in the +handler process. Since the full application state is typically too large for +capturing to disk and transmitting to an upstream server, the snapshot contains +a heuristically selected subset of the full state. + +The precise details of what’s captured varies between operating systems, but +generally includes the following +* The set of modules (executable, shared libraries) that are loaded into the + crashing process. +* An enumeration of the threads running in the crashing process, including the + register contents and the contents of stack memory of each thread. +* A selection of the OS-related state of the process, such as e.g. the command + line, environment and so on. +* A selection of memory potentially referenced from registers and from stack. + +To capture a crash dump, the crashing process is first suspended, then a +snapshot is created in the handler process. The snapshot includes the +CrashpadInfo structures of the modules loaded into the process, and the contents +of those is used to control the level of detail captured for the crash dump. + +Once the snapshot has been constructed, it is then written to a minidump file, +which is added to the database. The process is un-suspended after the minidump +file has been written. In the case of a crash (as opposed to a client request to +produce a dump without crashing), it is then either killed by the operating +system or the Crashpad handler. + +In general the snapshotting process has to be very intimate with the operating +system it’s working with, so there will be a set of concrete implementation +classes, many deriving from the snapshot interfaces, doing this for each +operating system. + +### Minidump + +The minidump implementation is responsible for writing a snapshot to a +serialized on-disk file in the minidump format. The minidump implementation is +OS-agnostic, as it works on an OS-agnostic Snapshot interface. + +TODO(siggi): Talk about two-phase writes and contents ordering here. + +### Database + +The Crashpad database contains persistent client settings, including a unique +crash client identifier and the upload-enabled bit. Note that the crash client +identifier is assigned by Crashpad, and is distinct from any identifiers the +client application uses to identify users, installs, machines or such - if any. +The expectation is that the client application will manage the user’s upload +consent, and inform Crashpad of changes in consent. + +The unique client identifier is set at the time of database creation. It is then +recorded into every crash report collected by the handler and communicated to +the upstream server. + +The database stores a configurable number of recorded crash dumps to a +configurable maximum aggregate size. For each crash dump it stores annotations +relating to whether the crash dumps have been uploaded. For successfully +uploaded crash dumps it also stores their server-assigned ID. + +The database consists of a settings file, named "settings.dat" with binary +contents (see crashpad::Settings::Data for the file format), as well as +directory containing the crash dumps. Additionally each crash dump is adorned +with properties relating to the state of the dump for upload and such. The +details of how these properties are stored vary between platforms. + +#### macOS + +The macOS implementation simply stores database properties on the minidump files +in filesystem extended attributes. + +#### iOS + +The iOS implementation also stores database properties of minidump files in +filesystem extended attributes. Separate from the database, iOS also stores its +intermediate dump files adjacent to the database. See more information about +[iOS intermediate +dumps.](ios_overview_design.md#the-crashpad-intermediatedump-format) + +#### Windows + +The Windows implementation stores database properties in a binary file named +“metadata†at the top level of the database directory. + +### Report Format + +Crash reports are recorded in the Windows minidump format with +extensions to support Crashpad additions, such as e.g. Annotations. + +### Upload to collection server + +#### Wire Format + +For the time being, Crashpad uses the Breakpad wire protocol, which is +essentially a MIME multipart message communicated over HTTP(S). To support this, +the annotations from all the CrashpadInfo structures found in the crashing +process are merged to create the Breakpad “crash keys†as form data. The +postmortem minidump is then attached as an “application/octet- stream†+attachment with the name “upload_file_minidumpâ€. The entirety of the request +body, including the minidump, can be gzip-compressed to reduce transmission time +and increase transmission reliability. Note that by convention there is a set of +“crash keys†that are used to communicate the product, version, client ID and +other relevant data about the client, to the server. Crashpad normally stores +these values in the minidump file itself, but retrieves them from the minidump +and supplies them as form data for compatibility with the Breakpad-style server. + +This is a temporary compatibility measure to allow the current Breakpad-based +upstream server to handle Crashpad reports. In the fullness of time, the wire +protocol is expected to change to remove this redundant transmission and +processing of the Annotations. + +#### Transport + +The embedding client controls the URL of the collection server by the command +line passed to the handler. The handler can upload crashes with HTTP or HTTPS, +depending on client’s preference. It’s strongly suggested use HTTPS transport +for crash uploads to protect the user’s privacy against man-in-the-middle +snoopers. + +TODO(mmentovai): Certificate pinning. + +#### Throttling & Retry Strategy + +To protect both the collection server from DDoS as well as to protect the +clients from unreasonable data transfer demands, the handler implements a +client-side throttling strategy. At the moment, the strategy is very simplistic, +it simply limits uploads to one upload per hour, and failed uploads are aborted. + +An experiment has been conducted to lift all throttling. Analysis on the +aggregate data this produced shows that multiple crashes within a short timespan +on the same client are nearly always due to the same cause. Therefore there is +very little loss of signal due to the throttling, though the ability to +reconstruct at least the full crash count is highly desirable. + +The lack of retry is expected to [change +soon](https://crashpad.chromium.org/bug/23), as this creates blind spots for +client crashes that exclusively occur on e.g. network down events, during +suspend and resume and such. + +### Extensibility + +#### Client Extensibility + +Clients are able to extend the generated crash reports in two ways, by +manipulating their CrashpadInfo structure. +The two extensibility points are: +1. Nominating a set of address ranges for inclusion in the crash report. +2. Adding user-defined minidump streams for inclusion in the crash report. + +In both cases the CrashpadInfo structure has to be updated before a crash +occurs. + +##### Embedder Extensibility + +Additionally, embedders of the handler can provide "user stream data source" +instances to the handler's main function. Any time a minidump is written, these +instances get called. + +Each data source may contribute a custom stream to the minidump, which can be +computed from e.g. system or application state relevant to the crash. + +As a case in point, it can be handy to know whether the system was under memory +or other resource duress at the time of crash. + +### Dependencies + +Aside from system headers and APIs, when used outside of Chromium, Crashpad has +a dependency on “mini_chromiumâ€, which is a subset of the Chromium base library. +This is to allow non-Chromium clients to use Crashpad, without taking a direct +dependency on the Chromium base, while allowing Chromium projects to use +Crashpad with minimum code duplication or hassle. When using Crashpad as part of +Chromium, Chromium’s own copy of the base library is used instead of +mini_chromium. + +The downside to this is that mini_chromium must be kept up to date with +interface and implementation changes in Chromium base, for the subset of +functionality used by Crashpad. + +## Caveats + +TODO(anyone): You may need to describe what you did not do or why simpler +approaches don't work. Mention other things to watch out for (if any). + +## Security Considerations + +Crashpad may be used to capture the state of sandboxed processes and it writes +minidumps to disk. It may therefore straddle security boundaries, so it’s +important that Crashpad handle all data it reads out of the crashed process with +extreme care. The Crashpad handler takes care to access client address spaces +through specially-designed accessors that check pointer validity and enforce +accesses within prescribed bounds. The flow of information into the Crashpad +handler is exclusively one-way: Crashpad never communicates anything back to +its clients, aside from providing single-bit indications of completion. + +## Privacy Considerations + +Crashpad may capture arbitrary contents from crashed process’ memory, including +user IDs and passwords, credit card information, URLs and whatever other content +users have trusted the crashing program with. The client program must acquire +and honor the user’s consent to upload crash reports, and appropriately manage +the upload state in Crashpad’s database. + +Crashpad must also be careful not to upload crashes for arbitrary processes on +the user’s system. To this end, Crashpad will never upload a process that hasn’t +registered with the handler, but note that registrations are inherited by child +processes on some operating systems. diff --git a/shared/sentry/external/crashpad/doc/status.md b/shared/sentry/external/crashpad/doc/status.md new file mode 100644 index 000000000..3948b4498 --- /dev/null +++ b/shared/sentry/external/crashpad/doc/status.md @@ -0,0 +1,44 @@ + + +# Project Status + +## Completed + +Crashpad has complete crash-reporting clients and some related tools for macOS, +Windows, Fuchsia, and Linux (including Android and Chromium OS).

It is responsible for +catching exceptions, writing crash reports, and uploading them to a crash report +collection server. Uploads are disabled by default, and can only be enabled by a +Crashpad client using the Crashpad client library, typically in response to a +user requesting this behavior. + +On macOS, this server may be started by its initial client, in which case it +performs a handshake with this client via a pipe established by the client that +is inherited by the server, referenced by the **--handshake-fd** argument. +During the handshake, the server furnishes the client with a send right that the +client may use as an exception port. The server retains the corresponding +receive right, which it monitors for exception messages. When the receive right +loses all senders, the server exits after allowing any upload in progress to +complete. + +Alternatively, on macOS, this server may be started from launchd(8), where it +receives the Mach service name in a **--mach-service** argument. It checks in +with the bootstrap server under this service name, and clients may look it up +with the bootstrap server under this service name. It monitors this service for +exception messages. Upon receipt of `SIGTERM`, the server exits after allowing +any upload in progress to complete. `SIGTERM` is normally sent by launchd(8) +when it determines that the server should exit. + +On Windows, clients register with this server by communicating with it via the +named pipe identified by the **--pipe-name** argument. Alternatively, the server +can inherit an already-created pipe from a parent process by using the +**--initial-client-data** mechanism. That argument also takes all of the +arguments that would normally be passed in a registration message, and so +constitutes registration of the first client. Subsequent clients may then +register by communicating with the server via the pipe. During registration, a +client provides the server with an OS event object that it will signal should it +crash. The server obtains the client’s process handle and waits on the crash +event object for a crash, as well as the client’s process handle for the client +to exit cleanly without crashing. When a server started via the +**--initial-client-data** mechanism loses all of its clients, it exits after +allowing any upload in progress to complete. + +On Windows, this executable is built by default as a Windows GUI app, so no +console will appear in normal usage. This is the version that will typically be +used. A second copy is also made with a `.com` extension, rather than `.exe`. In +this second copy, the PE header is modified to indicate that it’s a console app. +This is useful because the `.com` is found in the path before the `.exe`, so +when run normally from a shell using only the basename (without an explicit +`.com` or `.exe` extension), the `.com` console version will be chosen, and so +stdio will be hooked up as expected to the parent console so that logging output +will be visible. + +On Linux/Android, the handler may create a crash dump for its parent process +using **--trace-parent-with-exception**. In this mode, the handler process +creates a crash dump for its parent and exits. Alternatively, the handler may +be launched with **--initial-client-fd** which will start the server connected +to an initial client. The server will exit when all connected client sockets are +closed. + +It is not normally appropriate to invoke this program directly. Usually, it will +be invoked by a Crashpad client using the Crashpad client library, or started by +another system service. On macOS, arbitrary programs may be run with a Crashpad +handler by using [run_with_crashpad(1)](../tools/mac/run_with_crashpad.md) to +establish the Crashpad client environment before running a program. + +## Options + + * **--annotation**=_KEY_=_VALUE_ + + Sets a process-level annotation mapping _KEY_ to _VALUE_ in each crash report + that is written. This option may appear zero, one, or multiple times. + + Most annotations should be provided by the Crashpad client as module-level + annotations instead of process-level annotations. Module-level annotations + are more flexible in that they can be modified and cleared during the client + program’s lifetime. Module-level annotations can be set via the Crashpad + client library. Process-level annotations are useful for annotations that the + collection server requires be present, that have fixed values, and for cases + where a program that does not use the Crashpad client library is being + monitored. + + Breakpad-type collection servers only require the `"prod"` and `"ver"` + annotations, which should be set to the product name or identifier and + product version, respectively. It is unusual to specify other annotations as + process-level annotations via this argument. + + * **--database**=_PATH_ + + Use _PATH_ as the path to the Crashpad crash report database. This option is + required. Crash reports are written to this database, and if uploads are + enabled, uploaded from this database to a crash report collection server. If + the database does not exist, it will be created, provided that the parent + directory of _PATH_ exists. + + * **--handshake-fd**=_FD_ + + Perform the handshake with the initial client on the file descriptor at _FD_. + Either this option or **--mach-service**, but not both, is required. This + option is only valid on macOS. + + * **--initial-client-data**=*HANDLE_request_crash_dump*,*HANDLE_request_non_crash_dump*,*HANDLE_non_crash_dump_completed*,*HANDLE_first_pipe_instance*,*HANDLE_client_process*,*Address_crash_exception_information*,*Address_non_crash_exception_information*,*Address_debug_critical_section* + + Register the initial client using the inherited handles and data provided. + For more information on the argument’s format, see the implementations of + `CrashpadClient` and `ExceptionHandlerServer`. Either this option or + **--pipe-name**, but not both, is required. This option is only valid on + Windows. + + When this option is present, the server creates a new named pipe at a random + name and informs its client of the name. The server waits for at least one + client to register, and exits when all clients have exited, after waiting for + any uploads in progress to complete. + + * **--initial-client-fd**=_FD_ + + Wait for client requests on _FD_. Either this option or + **--trace-parent-with-exception**, but not both, is required. The handler + exits when all client connections have been closed. This option is only valid + on Linux platforms. + + * **--mach-service**=_SERVICE_ + + Check in with the bootstrap server under the name _SERVICE_. Either this + option or **--handshake-fd**, but not both, is required. This option is only + valid on macOS. + + _SERVICE_ may already be reserved with the bootstrap server in cases where + this tool is started by launchd(8) as a result of a message being sent to a + service declared in a job’s `MachServices` dictionary (see launchd.plist(5)). + The service name may also be completely unknown to the system. + + * **--metrics-dir**=_DIR_ + + Metrics information will be written to _DIR_. This option only has an effect + when built as part of Chromium. In non-Chromium builds, and in the absence of + this option, metrics information will not be written. + + * **--monitor-self** + + Causes a second instance of the Crashpad handler program to be started, + monitoring the original instance for exceptions. The original instance will + become a client of the second one. The second instance will be started with + the same **--annotation**, **--database**, **--monitor-self-annotation**, + **--no-rate-limit**, **--no-upload-gzip**, and **--url** arguments as the + original one. The second instance will always be started with a + **--no-periodic-tasks** argument, and will not be started with a + **--metrics-dir** argument even if the original instance was. + + Where supported by the underlying operating system, the second instance will + be restarted should it exit before the first instance. The second instance + will not be eligible to be started asynchronously. + + * **--monitor-self-annotation**=_KEY_=_VALUE_ + + Sets a module-level annotation mapping _KEY_ to _VALUE_ in the Crashpad + handler. This option may appear zero, one, or more times. + + If **--monitor-self** is in use, the second instance of the Crashpad handler + program will find these annotations stored in the original instance and will + include them in any crash reports written for the original instance. + + These annotations will only appear in crash reports written for the Crashpad + handler itself. To apply a process-level annotation to all crash reports + written by an instance of the Crashpad handler, use **--annotation** instead. + + * **--monitor-self-argument**=_ARGUMENT_ + + When directed by **--monitor-self** to start a second instance of the + Crashpad handler program, the second instance will be started with _ARGUMENT_ + as one of its arguments. This option may appear zero, one, or more times. + This option has no effect in the absence of **--monitor-self**. + + This supports embedding the Crashpad handler into a multi-purpose executable + that dispatches to the desired entry point based on a command-line argument. + To prevent excessive accumulation of handler processes, _ARGUMENT_ must not + be `--monitor-self`. + +* **--no-identify-client-via-url** + + Do not add client-identifying fields to the URL. By default, `"prod"`, + `"ver"`, and `"guid"` annotations are added to the upload URL as name-value + pairs `"product"`, `"version"`, and `"guid"`, respectively. Using this + option disables that behavior. + + * **--no-periodic-tasks** + + Do not scan for new pending crash reports or prune the crash report database. + Only crash reports recorded by this instance of the Crashpad handler will + become eligible for upload in this instance, and only a single initial upload + attempt will be made. + + This option is not intended for general use. It is provided to prevent + multiple instances of the Crashpad handler from duplicating the effort of + performing the same periodic tasks. In normal use, the first instance of the + Crashpad handler will assume the responsibility for performing these tasks, + and will provide this argument to any second instance. See + **--monitor-self**. + + * **--no-rate-limit** + + Do not rate limit the upload of crash reports. By default uploads are + throttled to one per hour. Using this option disables that behavior, and + Crashpad will attempt to upload all captured reports. + + * **--no-upload-gzip** + + Do not use `gzip` compression for uploaded crash reports. Normally, the + entire request body is compressed into a `gzip` stream and transmitted with + `Content-Encoding: gzip`. This option disables compression, and is intended + for use with collection servers that don’t accept uploads compressed in this + way. + + * **--no-write-minidump-to-database** + + Do not write the minidump to database. Normally, the minidump is written to + database for upload. Use this option with **--write-minidump-to-log** to + only write the minidump to log. This option is only available to Android. + + * **--pipe-name**=_PIPE_ + + Listen on the given pipe name for connections from clients. _PIPE_ must be of + the form `\\.\pipe\`. Either this option or + **--initial-client-data**, but not both, is required. This option is only + valid on Windows. + + When this option is present, the server creates a named pipe at _PIPE_, a + name known to both the server and its clients. The server continues running + even after all clients have exited. + + * **--reset-own-crash-exception-port-to-system-default** + + Causes the exception handler server to set its own crash handler to the + system default before beginning operation. This is only expected to be useful + in cases where the server inherits an inappropriate crash handler from its + parent process. This option is only valid on macOS. Use of this option is + discouraged. It should not be used absent extraordinary circumstances. + + * **--sanitization-information**=_SANITIZATION-INFORMATION-ADDRESS_ + + Provides sanitization settings in a SanitizationInformation struct at + _SANITIZATION-INFORMATION-ADDRESS_. This option requires + **--trace-parent-with-exception** and is only valid on Linux platforms. + + * **--shared-client-connection** + + Indicates that the file descriptor provided by **--initial-client-fd** is + shared among mulitple clients. Using a broker process is not supported for + clients using this option. This option is only valid on Linux platforms. + + * **--trace-parent-with-exception**=_EXCEPTION-INFORMATION-ADDRESS_ + + Causes the handler process to trace its parent process and exit. The parent + process should have an ExceptionInformation struct at + _EXCEPTION-INFORMATION-ADDRESS_.

It was contributed by Apple as a way to enable clang++ to port to +platforms that do not have a system unwinder. It is intended to be a small and +fast implementation of the ABI, leaving off some features of HP's libunwind +that never materialized (e.g. remote unwinding). + +The unwinder has two levels of API. The high level APIs are the `_Unwind_*` +functions which implement functionality required by `__cxa_*` exception +functions. The low level APIs are the `unw_*` functions which are an interface +defined by the old HP libunwind project. + +Getting Started with libunwind +------------------------------ + +.. toctree:: + :maxdepth: 2 + + BuildingLibunwind + +Current Status +-------------- + +libunwind is a production-quality unwinder, with platform support for DWARF +unwind info, SjLj, and ARM EHABI. + +The low level libunwind API was designed to work either in-process (aka local) +or to operate on another process (aka remote), but only the local path has been +implemented.

In particular, if AddNonOwnedMemory() is used to add multiple + //! overlapping ranges, then overlapping ranges will still be emitted to the + //! minidump. Currently, AddNonOwnedMemory() is used only for adding thread + //! stacks, so overlapping shouldn't be a problem in practice.

Its arguments argc +and argv are the argument count and array as passed to the main() function +on program invocation. The argument optstring is a list of available option +characters. If such a character is followed by a colon (`:'), the option +takes an argument, which is placed in optarg. If such a character is +followed by two colons, the option takes an optional argument, which is +placed in optarg. If the option does not take an argument, optarg is NULL. + +The external variable optind is the index of the next array element of argv +to be processed; it communicates from one call to the next which element to +process. + +The getopt_long() function works like getopt() except that it also accepts +long options started by two dashes `--'. If these take values, it is either +in the form + +--arg=value + + or + +--arg value + +It takes the additional arguments longopts which is a pointer to the first +element of an array of type GETOPT_LONG_OPTION_T. The last element of the +array has to be filled with NULL for the name field. + +The longind pointer points to the index of the current long option relative +to longopts if it is non-NULL. + +The getopt() function returns the option character if the option was found +successfully, `:' if there was a missing parameter for one of the options, +`?' for an unknown option character, and EOF for the end of the option list. + +The getopt_long() function's return value is described in the header file. + +The function getopt_long_only() is identical to getopt_long(), except that a +plus sign `+' can introduce long options as well as `--'. + +The following describes how to deal with options that follow non-option +argv-elements. + +If the caller did not specify anything, the default is REQUIRE_ORDER if the +environment variable POSIXLY_CORRECT is defined, PERMUTE otherwise. + +REQUIRE_ORDER means don't recognize them as options; stop option processing +when the first non-option is seen. This is what Unix does. This mode of +operation is selected by either setting the environment variable +POSIXLY_CORRECT, or using `+' as the first character of the optstring +parameter. + +PERMUTE is the default. We permute the contents of ARGV as we scan, so that +eventually all the non-options are at the end. This allows options to be +given in any order, even with programs that were not written to expect this. + +RETURN_IN_ORDER is an option available to programs that were written to +expect options and other argv-elements in any order and that care about the +ordering of the two. We describe each non-option argv-element as if it were +the argument of an option with character code 1. Using `-' as the first +character of the optstring parameter selects this mode of operation. + +The special argument `--' forces an end of option-scanning regardless of the +value of ordering. In the case of RETURN_IN_ORDER, only `--' can cause +getopt() and friends to return EOF with optind != argc. + +COPYRIGHT NOTICE AND DISCLAIMER: + +Copyright (C) 1997 Gregory Pietsch + +This file and the accompanying getopt.h header file are hereby placed in the +public domain without restrictions.

It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15.

These are all documented in the top of the header in a big +comment block, so refer to that instead. + +## Caveats + +### ABI differences + +Some functions that the standard C library exposes use a different ABI than +what the Linux kernel uses. Care must be taken when making syscalls directly +that you use the right structure and flags. e.g. Most C libraries define a +`struct stat` (commonly in `sys/stat.h` or `bits/stat.h`) that is different +from the `struct stat` the kernel uses (commonly in `asm/stat.h`). If you use +the wrong structure layout, then you can see errors like memory corruption or +weird/shifted values. If you plan on making syscalls directly, you should +focus on headers that are available under the `linux/` and `asm/` namespaces. + +Note: LSS provides structs for most of these cases. For `sys_stat()`, it +provides `struct kernel_stat` for you to use. + +### Transparent backwards compatibility with older kernels + +While some C libraries (notably, glibc) take care to fallback to older syscalls +when running on older kernels, there is no such support in LSS. If you plan on +trying to run on older kernels, you will need to handle errors yourself (e.g. +`ENOSYS` when using a too new syscall). + +Remember that this can happen with new flag bits too. e.g. The `O_CLOEXEC` +flag was added to many syscalls, but if you try to run use it on older kernels, +it will fail with `EINVAL`. In that case, you must handle the fallback logic +yourself. + +### Variable arguments (varargs) + +We do not support vararg type functions. e.g. While the standard `open()` +function can accept 2 or 3 arguments (with the mode field being optional), +the `sys_open()` function always requires 3 arguments. + +## Bug reports & feature requests + +If you wish to report a problem or request a feature, please file them in our +[bug tracker](https://bugs.chromium.org/p/linux-syscall-support/issues/). + +Please do not post patches to the tracker. Instead, see below for how to send +patches to us directly. + +While we welcome feature requests, please keep in mind that it is unlikely that +anyone will find time to implement them for you. Sending patches is strongly +preferred and will often move things much faster. + +## Projects that use LSS + +* [Chromium](https://www.chromium.org/) +* [Breakpad](https://chromium.googlesource.com/breakpad/breakpad) +* [Native Client](https://developer.chrome.com/native-client), in nacl\_bootstrap.c + +## How to get an LSS change committed + +### Review + +You get your change reviewed, you can upload it to +[Gerrit](https://chromium-review.googlesource.com/q/project:linux-syscall-support+status:open) +using `git cl upload` from +[Chromium's depot-tools](https://commondatastorage.googleapis.com/chrome-infra-docs/flat/depot_tools/docs/html/depot_tools_tutorial.html). + +### Testing + +Tests are found in the [tests/](./tests/) subdirectory. It does not (yet) offer +100% coverage, but should grow over time. + +New commits that update/change/add syscall wrappers should include tests for +them too.

For new system headers, try + to add them here rather than copying to exact unittest (if possible). + It might slow compilation down slightly, but makes the code easier to manage. + Make sure it is included first. +* Use `assert()` on everything to check return values. +* Use `sys_xxx()` to access the syscall via LSS (compared to `xxx()` which tends + to come from the C library). +* If you need a tempfile, use `tempfile.XXXXXX` for templates with helpers like + `mkstemp`. Try to clean them up when you're done with them. + These will be created in the cwd, but that's fine. +* Don't worry about trying to verify the kernel/C library API and various edge + cases. The goal of LSS is to make sure that we pass args along correctly to + the syscall only. +* Make sure to leave comments in the test so it's clear what behavior you're + trying to verify (and how). + +Feel free to extend [test_skel.h] with more helpers if they're useful to more +than one test. + +If you're looking for a simple example, start with [unlink.c](./unlink.c). +You should be able to copy this over and replace the content of `main()`. + +## Running The Tests + +Simply run `make`. This will compile & execute all the tests on your local +system. A standard `make clean` will clean up all the objects. + +If you need to debug something, then the programs are simply named `xxx_test` +and can easily be thrown into `gdb ./xxx_test`. + +We have rudimentary cross-compile testing via gcc and clang. Try running +`make cross` -- for any toolchains you don't have available, it should skip +things automatically.

An +// application may pass FilePath objects around internally, masking the +// underlying differences between systems, only differing in implementation +// where interfacing directly with the system. For example, a single +// OpenFile(const FilePath &) function may be made available, allowing all +// callers to operate without regard to the underlying implementation. On +// POSIX-like platforms, OpenFile might wrap fopen, and on Windows, it might +// wrap _wfopen_s, perhaps both by calling file_path.value().c_str().

These methods are highly +// recommended over attempting to split and concatenate strings directly. +// These methods are based purely on string manipulation and knowledge of +// platform-specific pathname conventions, and do not consult the filesystem +// at all, making them safe to use without fear of blocking on I/O operations. +// These methods do not function as mutators but instead return distinct +// instances of FilePath objects, and are therefore safe to use on const +// objects. The objects themselves are safe to share between threads. +// +// To aid in initialization of FilePath objects from string literals, a +// FILE_PATH_LITERAL macro is provided, which accounts for the difference +// between char[]-based pathnames on POSIX systems and wchar_t[]-based +// pathnames on Windows. +// +// Paths can't contain NULs as a precaution agaist premature truncation. +// +// Because a FilePath object should not be instantiated at the global scope, +// instead, use a FilePath::CharType[] and initialize it with +// FILE_PATH_LITERAL. At runtime, a FilePath object can be created from the +// character array. Example: +// +// | const FilePath::CharType kLogFileName[] = FILE_PATH_LITERAL("log.txt"); +// | +// | void Function() { +// | FilePath log_file_path(kLogFileName); +// | [...] +// | } +// +// WARNING: FilePaths should ALWAYS be displayed with LTR directionality, even +// when the UI language is RTL.
