- Added Cloud KMS support for Google Cloud Storage resources, allowing the use of customer-managed encryption keys (CMEKs). Bucket-related functionality includes the new "kms" command, which can be used to get or set a bucket's default KMS key. Concerning objects, users may now specify the CMEK to be used for encryption via their boto config file, in the "encryption_key" attribute. In this way, users may specify either a CSEK or a CMEK to encrypt new objects, but not both. For more information, see "gsutil help encryption".
- Several documentation updates and clarifications.
- Added transport compression support, available through the "-j" and "-J" options for the "cp", "mv", and "rsync" commands. This is useful when uploading files with highly-compressible content. When specificed, files being uploaded are compressed on-the-fly in memory, sent to GCS, and uncompressed by GCS before they are stored. See "gsutil help cp" for additional information.
- When "use_magicfile=True" is set in the boto config file, gsutil will now append the detected charset, if present, to the object's Content-Type metadata field. For example, a Content-Type might be populated with "text/html; charset=us-ascii" rather than simply "text/html".
- Improved error handling and logging for upload resumption.
- After encountering a PreconditionException, the "acl ch" command will now re-fetch the object generation before retrying.
- Fixed issue with parsing lifecycle conditions when using the XML API. Conditions whose values could be evaluated by Python as "falsy" (e.g. setting an "age" condition to the number 0 or "isLive" to false) would be omitted from the lifecycle configuration when "prefer_api=xml" was set in the boto config file. Note that the JSON API is preferred by default, so most users were unlikely to encounter this issue.
- For commands that fetch bucket ACLs or default ACLs, when the user does not have storage.buckets.getIamPolicy on the GCS bucket, using the XML API will now behave consistently with the JSON API and display ACL/default ACL fields as empty, rather than throwing a CommandException.
- Several documentation updates and clarifications.
- The "signurl" command now uses signature V4 signing format to generate URLs.
- Added newest version of the Boto library, which includes support for using Signature Version 4 to connect to S3 buckets via the "use-sigv4 = True" and "host = s3..amazonaws.com" Boto options under the "[s3]" section.
- Added support for Requester Pays functionality when making requests to GCS buckets with this feature enabled. For example usage, see the entry for "-u" in "gsutil help options". Requester Pays is currently only supported for requests using the GCS JSON API; XML API support will be added in a later version.
- Fixed issue where attempting to preserve ACLs by using "-p" with cp/mv/rsync would fail when the destination is a local file.
- Improved quality of several ambiguous error messages.
- The proxy_rdns option is now True by default when a proxy is set. Also added Boto config file comments explaining that gcloud proxy options, if present, take precedence over corresponding Boto settings and environment variable settings.
- Following the deprecation of Python 2.6 support for gsutil, code sections that were only present to support Python 2.6 have been removed.
- Several documentation updates and clarifications.
- When using the JSON API, the "ls -L" and "stat" commands now print an object's storage class update time if it differs from the object's creation time; this occurs when the storage class has been changed due to the bucket's lifecycle management configuration.
- Listing a bucket's metadata via "ls -Lb" now prints its metageneration.
- When specifying custom metadata values using the top-level -h option, such values may now include unicode characters as well as multiple ":" characters.
- For Cloud SDK (gcloud) distributions of gsutil, if you have configured the Cloud SDK to not pass credentials to gsutil (by running "gcloud config set pass_credentials_to_gsutil false"), gsutil will now correctly work with credentials obtained via "gsutil config". This would previously result in an error with a message to run "gcloud auth login". Additionally, the "gsutil config" command no longer prompts users to run "gcloud auth login" if this option is set to false. This should allow switching between stand-alone gsutil installations and gcloud-packaged gsutil installations more easily.
- The config_file_list section in debug output now displays files in the order that they are loaded.
- Added XML support for some commands which previously only worked via the JSON API ("lifecycle" and "defstorageclass").
- Several documentation updates and clarifications.
- The cp command now supports reading from and writing to named pipes.
- Fixed issue where tab completion wasn't working.
- Fixed issue when using the XML API where gsutil would fail to parse bucket metadata for buckets using Lifecycle rules containing the SetStorageClass action or MatchesStorageClass condition.
- Removed -o flag from "notification create" command. The same functionality is available with the -p flag; the -o flag had been mistakenly added in a previous change.
- Removed the alpha disclaimer from the iam command help text.
- Several documentation updates and clarifications.
- Added bucket label support to gsutil. For more details, see https://cloud.google.com/compute/docs/label-or-tag-resources.
- Added the label command, which can be used to get, set, and change the labels for an existing bucket (known as "tags" for S3 buckets).
- Listing a bucket via "gsutil ls -Lb" now also displays the labels, if any exist, that are currently set on it.
- Added support for configuring GCS Cloud Pub/Sub notifications. For more details, see https://cloud.google.com/storage/docs/pubsub-notifications.
- Added support for specifying canned ACLs when using the rsync command.
- Fixed a bug where error messages about invalid object names did not correctly display the problematic object name.
- Fixed "referenced before assignment" error in some copy_helper exceptions for resumable uploads and non-resumable cloud-to-local downloads.
- The setmeta command now properly supports case sensitivity in custom metadata keys when using the JSON API.
- Fixed a resource leak affecting Windows in cases where single-process, multithreaded parallelism is used that would result in an OSError with the message "Too many open files".
- Fixed HTTPError initialization failure in signurl command.
- Fixed signurl issue where attempting to validate short-lived URLs on a slow connection would fail because of URL expiration.
- Fixed a bug where cp -r would not properly resolve wildcards for cloud-to-cloud copies.
- Fixed a bug where cp -e -r would copy symlinks.
- Fixed a bug where cp -P would fail on Windows.
- Fixed a bug where version -l might not show all boto configuration files.
- Running perfdiag now only lists the objects that were created by that run of perfdiag. This fixes an issue where running perfdiag against an existing bucket with many objects in it could take a long time.
- Simplified parallelism when using a single process with multiple threads. With this change, gsutil will spawn a new thread pool per level of parallelism. As an example, if you specify that you want a parellel_thread_count of 24, this will result in 24 worker threads, except when you're using parallel composite uploads or sliced downloads, in which case 48 (24 * 2) worker threads will be used.
- Extended the early deletion warning threshold when moving Coldline objects to 90 days after object creation.
- Improved several error messages and warnings.
- Several documentation updates and clarifications.
- Added per-object storage class functionality to gsutil. For more details, see https://cloud.google.com/storage/docs/per-object-storage-class.
- Added the defstorageclass command, which can be used to get and set an existing bucket's default storage class.
- The cp, mv, and rewrite commands now support the "-s" option, allowing users to specify the storage class for destination object(s). When no storage class is specified, the object's storage class will be assigned from either its bucket's default storage class (cp/mv commands) or the source object's storage class (rewrite command).
- Fixed a bug in POSIX preservation for the cp and mv commands where POSIX attributes were not propagated to cloud objects, even when the -P flag was present.
- Fixed a bug in setmeta where removing custom metadata would add an empty-string value if the key did not already exist.
- Content-Type is now obtained from symlink targets, rather than symlinks themselves, when the use_magicfile option is set in the .boto configuration file.
- Analytics reporting now includes performance metrics such as average throughput and thread idle time.
- The iam set command now supports a -e option to specify an etag precondition check. The IAM policy file returned by iam get and used by iam set has also been altered to include this field.
- Default limit for max number of processes changed to 64.
- Several documentation updates and clarifications.
- The console output for many commands has been improved to display command progress.
- The cp, mv, and rsync commands now support a -P option that preserves POSIX file attributes from the source. Currently, mode, gid, uid, atime, and mtime attributes are supported for uploads, downloads, and copies.
- gsutil can now optionally report anonymous usage statistics that help gsutil developers improve the tool. For non-gcloud distributions, prompts have been added to the config and update commands. Prompts can be disabled via the disable_analytics_prompt value in the .boto configuration file.
- Added the iam commmand, which can be used to set IAM policies on Google Cloud Storage buckets and objects. This feature is currently in alpha and requires a whitelist application to use it - see "gsutil help iam" for details.
- The hash command now supports retrieving hashes for cloud objects.
- Fixed a bug where rsync -e -r could fail for subdirectories with broken symlinks.
- Fixed an access error when interacting with S3 user-specific directories.
- Updated boto library dependency to 2.42.0.
- gsutil now outputs a message that estimates the total number of objects for commands affecting more than 30,000 objects. This value can be adjusted via task_estimation_threshold in the .boto configuration file.
- Fixed a bug in resumable downloads that could raise UnboundLocalError if the download file was not readable.
- Updated oauth2client to version 2.2.0, fixing some IOError and OSError cases.
- Fixed bug in gsutil ls that would show update time instead of creation time when using the JSON API and -L or -l flags.
- Fixed a bug in gsutil rsync -d that could cause erroneous removal of an extra destination object.
- Fixed downloads to include accept-encoding:gzip logic when appropriate.
- gsutil rsync now stores modification time (mtime) for cloud objects.
- Changed the default change detection algorithm of gsutil rsync from file size to file mtime, falling back to checksum and finally file size as alternatives. This allows for increased accuracy of rsync without the speed sacrifice that comes from checksum calculation, and makes gsutil rsync work more similarly to how Linux rsync works. Note that the first run of a local-to-cloud rsync using this new algorithm may be slower than subsequent runs, as the cloud objects will not initially have an mtime, and the algorithm will fall back to the slower checksum-based alternative in addition to adding mtime to the cloud objects.
- When using the JSON API, gsutil will output a progress message before retrying a request if enough time has passed since the first attempt.
- Improved error detection in dry runs of gsutil rsync by attempting to open files that would be copied.
- Added time created and time updated properties to output of gsutil ls -Lb.
- Added archived time property to output of gsutil ls -La and gsutil stat.
- Changed minimum number of source objects for gsutil compose from 2 to 1.
- Removed an HTTP metadata get call from cp, acl, and setmeta commands. This improves the speed of gsutil cp for small objects by over 50%.
- Several documentation updates and clarifications.
- gsutil support for Python 2.6 is deprecated, and gsutil will stop supporting Python 2.6 on September 1, 2016. This change is being made for two reasons. First, Python 2.6 stopped receiving security patches since October 2013. Second, removing Python 2.6 support will enable gsutil to add support for Python 3. Versions of gsutil released prior to September 1, 2016 will continue to work with Python 2.6. However, bug fixes will not be made retroactively to older gsutil versions, and users reporting bugs will be asked to upgrade to the current gsutil version (using Python 2.7, or, when it is supported, Python 3).
- Improved documentation around Cloud SDK (gcloud) installs.
- gsutil now supports the beta Customer-Supplied Encryption Keys features for Google Cloud Storage objects, via the JSON API. This feature allows you to encrypt your data with keys that are not permanently stored on Google's servers. You can provide encryption and decryption keys in your .boto configuration file. As long as an encryption key is specified in the configuration file, all gs:// objects that gsutil creates will be stored encrypted with that key, and all encrypted objects will be decrypted when downloaded. See "gsutil help csek" for more information.
- Added the rewrite command, which can be used to perform key rotation for objects encrypted with customer-supplied encryption keys.
- Fixed an AttributeError that could occur when running in debug mode for operations involving wildcards, recursion, or listing.
- Fixed an ArgumentException that could occur when using perfdiag write throughput tests with parallelism.
- Restored debug mode output for resumable uploads using the JSON API.

- Fixed a bug where cp -R of a single file with a destination other than the bucket root would copy to the bucket root.
- Fixed a bug when using a single process with multiple threads where CTRL-C would not stop the process until one thread completed a task.
- Improved exception logging in debug mode.
- Added "cache-control: no-transform" to all uploads using compression ("gsutil cp -z" or "gsutil cp -Z") to ensure that doubly-compressed objects can be downloaded with data integrity checking.
- Reduced the default number of threads per-process on Linux systems from 10 to 5.
- Documented additional OS X Unicode limitations.
- The config command now includes the custom client ID and secret in the configuration file output if the command is run with those values configured.
- Fixed an oauth2client dependency break that caused the PyPi distribution of gsutil to allow oauth2client 2.0.0, causing all commands to fail with an ImportError.
- Fixed a bug where gsutil could leak multiprocessing.Manager processes when terminating signals (such as CTRL-C) were sent.
- Fixed a bug where the -q option did not suppress output from the stat command.
- Fixed a bug where deleting an empty bucket with rm -r would return a non-zero exit code even when successful.
- Fixed UnicodeEncodeErrors that could occur when using the du command with a pipe on objects containing non-ASCII characters.
- Many documentation improvements and clarifications.
- The ls command now supports a -d option (similar to Unix ls -d) for suppressing recursion into subdirectories.
- The signurl command now accepts JSON-format private key files generated by the Google Developers Console.
- The signurl command now supports generating resumable upload start URLs.
- The cp command now supports a -Z option which will gzip-compress all files (regardless of their extensions) as they are uploaded.
- Fixed a bug where an expired OAuth2 token could include the OAuth2 token response as part of the download, causing it to fail end-to-end integrity checks and be deleted.
- Fixed a bug where streaming downloads using the JSON API would restart from the beginning of the stream if the connection broke. This bug could also cause data corruption in streaming downloads, because streaming downloads are not validated with end-to-end integrity checks.
- Fixed an internal_failure exception that could occur when an OAuth2 token refresh returned a transient error, such as an HTTP 503.
- Fixed a resource deadlock exception in oauth2client that could cause sliced downloads to hang.
- Fixed a bug where cp/rsync -p would use the default object ACL for the destination object if the caller did not have OWNER permission on the source object.
- Fixed a potential race condition when using perfdiag with multiple threads and/or processes.
- Fixed an AttributeError that could occur when using acl ch -p.
- Fixed a bug where the mv command did not properly handle the global -m flag.
- Fixed a UnicodeEncodeError that could occur when iterating over non-Unicode-named directories.
- Fixed a bug where an object name including a wildcard could cause an infinite loop during a recursive listing.
- Fixed a Unicode bug when using cp or ls on Windows on an object containing certain Unicode characters. However, even with this fix Unicode can still be problematic on Windows; consult "gsutil help encoding" for details.
- Fixed a Windows performance issue during rsync diff generation.
- Fixed a bug in the ordering of ls output.
- Fixed a bug where Windows help output included ANSI escape codes.
- Fixed a compatibility bug with perfdiag -i with input generated prior to gsutil 4.14.
- Several documentation updates, including rsync exclusion pattern matching, service account configuration, cp/rsync recursion flags, multi-object rm, versioned URL removal, destination subdirectory naming, wildcard behavior, regional buckets, and s3 connection reset.
- Improvements to Unicode documentation including LANG variable and iconv tool.
- Fixed an OverflowError in apitools that caused download failures for large files on 32-bit machines.
- Removed unnecessary sending of range headers for downloads when using the XML API.
- Fixed a bug that caused perfdiag to report extremely high throughput when the -p flag was unspecified and exactly one of the -c or -k flags were specified.
- Fixed a ValueError that occurred on Python 2.6 with sliced object downloads.
- HTTP connections for downloads and uploads in the JSON API are now re-used per-thread.
- When gsutil's automatic update feature prompts and the user chooses to update, gsutil will now exit with status code 1 after updating (because the original command was not executed).
- The cp -A flag is disabled when using gsutil -m to ensure that ordering is preserved when copying between versioned buckets.
- Implemented Sliced Object Download feature. This breaks up a single large object into multiple pieces and downloads them in parallel, improving performance. The gsutil cp, mv and rsync commands now use this by default when compiled crcmod is available for performing fast end-to-end integrity checks. If compiled crcmod is not available, normal object download will be used. Sliced download can be used in conjunction with the global -m flag for maximum performance to download multiple objects in parallel while additionally slicing each object. See the "SLICED OBJECT DOWNLOAD" section of "gsutil help cp" for details. Note: sliced download may cause performance degradation for disks with very slow seek times. You can disable this feature by setting sliced_object_download_threshold = 0 in your .boto configuration file.
- Added rthru_file and wthru_file test modes to perfdiag, allowing measurement of reads and writes from a disk. This also allows measurement of transferring objects too large to fit in memory. The size restriction of 20GiB has been lifted.
- perfdiag now supports a -p flag to choose a parallelism strategy (slice, fan, or both) when using multiple threads and/or processes.
- Fixed an IOError that could occur in apitools when acquiring credentials using multiple threads and/or processes on Google Compute Engine.
- Fixed a bug where rm -r would attempt to delete a nonexistent bucket.
- Fixed a bug where a default object ACL could not be set or changed to empty.
- Fixed a bug where cached credentials corresponding to an old account could be used (for example, credentials associated with a prior .boto configuration file).
- Fixed a bug in apitools for retrieving byte ranges of size 1 (for example, "cat -r 1-1 ...")
- Fixed a bug that caused the main gsutil process to perform all work leaving all gsutil child processes idle.
- Fixed a bug that caused multiple threads not to be used when multiprocessing was unavailable.
- Fixed a bug that caused rsync to skip files that start with "." when the -r option was not used.
- Fixed a bug that caused rsync -C to bail out when it failed to read a source file.
- Fixed a bug where gsutil stat printed unwanted output to stderr.
- Fixed a bug where a parallel composite upload could return a nonzero exit code even though the upload completed successfully. This occurred if temporary component deletion triggered a retry but the original request succeeded.
- Fixed a bug where gsutil would exit with code 0 when both running in debug mode and encountering an unhandled exception.
- Fixed a bug where gsutil would suggest using parallel composite uploads multiple times.
- Bucket removal is now supported even if billing is disabled for that bucket.
- Refactored Windows installs to no longer use any multiprocessing module functions, as gsutil has never supported multiple processes on Windows. Multithreading is unaffected and still available on Windows.
- All downloads are now written to a temporary file with a "_.gstmp" suffix while the download is still in progress.
- Re-hashing of existing bytes when resuming downloads now displays progress.
- Reduced the total number of multiprocessing.Manager processes to two.
- The rm command now correctly counts the number of objects that could not be removed.
- Increased the default retries to match the Google Cloud Storage SLA. By default, gsutil will now retry 23 times with exponential backoff up to 32 seconds, for a total timespan of ~10 minutes.
- Improved bucket subdirectory checks to a single HTTP call. Detection of _$folder$ placeholder objects is now eventually consistent.
- Eliminated two unnecessary HTTP calls when performing uploads via the cp, mv, or rsync commands.
- Updated documentation for several topics including acl, cache-control, crcmod, cp, mb, rsync, and subdirs.
- Added a warning about using parallel composite upload with NEARLINE storage-class buckets.
- Added -U flag to cp and rsync commands to allow skipping of unsupported object types.
- Added support for Google Developer Shell credentials.
- Precondition headers (x-goog-if-...) are now respected for the setmeta command.

- Fixed a bug in the compose command where a missing source object resulted in an error message claiming the destination object was missing.
- Added a help section on throttling gsutil.
- Resumable uploads will now start over if a PUT to the upload ID returns an HTTP 404. Previously this behavior applied only to an HTTP 410.
- XML API resumable uploads now retry on HTTP 429 errors, matching the behavior of JSON API resumable uploads.
- Improved response to process kill signals, reducing the likelihood of leaving orphaned child processes and temporary files.
- Bucket lifecycle configuration now works for S3.
- Removed the deprecated setmeta -n option.
- Added support for JSON-format service account private key files.
- Added support for the Rewrite API (JSON API only). This is used for all copies within the Google Cloud and supports copying objects across storage classes and/or locations.
- Fixed a bug that could cause downloads to have a hash mismatch (and deletion of the corrupted file) when resumed across process breaks via a tracker file.
- Updated documentation and examples for several topics including acl, cp, dev, signurl, stat, and wildcards.
- Added Nearline storage class support to the mb command.
- Fixed a bug for streaming uploads that could occasionally cause a HTTP 410 from the service or a hash mismatch (and deletion of the corrutped file).
- Fixed an OverflowError that occurred when uploading files > 4GiB on a 32-bit operating system.
- Added documentation around using the Content-MD5 header to extend integrity checking to include checksums computed by a client-side content pipeline.
- Fixed a bug that could cause undetected data corruption (preserving incorrect data) if a streaming upload encountered a service error on non-8KiB-aligned boundary.
- Fixed a bug that caused downloads to be truncated if the connection broke, resulting in a hash mismatch (and deletion of the corrupted file) for that download.
- Fixed a format string arguments error that occurred if a download exhausted all retries.
- The lifecycle command now accepts JSON input in the form of "{ "lifecycle": { "rule" ..." in addition to "{ "rule": ...".
- Improved access token expiry logic for GCE credentials.
- When using the JSON API, the ch acl/defacl subcommand now supports project groups via the -p flag. For details, see "gsutil help acl ch".
- Fixed a bug that caused daisy-chain copies (including cross-provider copies) for files large than 100MiB to fail.
- Fixed a bug that caused streaming uploads than ran for longer than an hour to fail with HTTP 400s.
- Fixed a bug where perfdiag would not properly clean up its test files.
- Fixed a bug where using ls with the XML API could mistakenly report bucket configuration as present.
- Updated documentation for metadata, retries, security, and subdirs.
- Tracker files are no longer written for small downloads.
- gsutil now supports HTTP proxy configuration via the http_proxy, https_proxy, or HTTPS_PROXY environment variables. This configuration is used only if proxy configuration is not present in the .boto configuration file.

- Fixed a bug where rsync temporary listing files were not being cleaned up when the rsync process was killed.
- Fixed a bug where rsync would remove destination URLs if listing the source encountered a non-retryable failure (for example, if the source did not exist).
- Fixed a bug where mv would fail for some Unicode filenames.
- Fixed a bug where mv would remove the source URL after skipping the destination URL.
- Fixed a bug that caused daisy chain uploads to hang if the download thread raised an exception.
- Fixed a bug where acl ch would return a zero exit code even if it failed.
- Fixed a bug that sometimes caused the progress display to render multiple times at the end of an upload or download.
- Resumable uploads of files using the JSON API now send their data in a single request, making separate HTTP calls only when resuming is necessary.
- The test command now runs tests in parallel by default, and test parallelism on Windows is now supported.
- All non-streaming downloads are now resumable (and retryable) by default, regardless of size.
- Canned ACLs and canned default object ACLs are now supported in the JSON API (previously they would fall back to using the XML API).

- Improved detection of the Google Compute Engine metadata server, particularly when using the -m flag for multiprocessing.
- Added new help sections about filename encoding and security/privacy considerations.
- Download progress is now displayed for small XML API downloads.
- Tab completion now works on gs:// URLs (for Cloud SDK installs only). To install via Cloud SDK, see https://cloud.google.com/sdk/#Quick_Start
- Streaming uploads (with source URL "-") using the JSON API now buffer in-memory up to 100MB, allowing large streams to be retried in the event of network flakiness or service errors.
- Resumable uploads that receive a fatal service error (typically a 410) are now automatically retried from the beginning.
- Fixed an apitools bug that impacted upload performance and caused "Retrying from byte __ after exception" to print after every 100MiB.
- Fixed _$folder$ placeholder object detection on versioned buckets.
- Removed an unnecessary credential check on load which increased startup time by over one second in some cases.
- SignURL now properly retries when checking if the signed object is readable.

- The x-goog-if-generation-match:0 header now works properly with the XML API.
- Fixed a bug that caused "defacl ch" on a bucket with a private ACL to fail.
- The rm command now properly supports precondition headers.
- Fixed a bug that caused large streaming uploads to fail with the message "Failure: length too large" when using the JSON API.
- Fixed a bug that caused JSON lifecycle configurations with createdBefore conditions to fail with a DecodeError.
- Byte counts now display accurate abbreviations of binary sizing. For example, messages previously labeled MB are now properly labeled MiB to indicate 2**20 bytes. Only the labeling changed - the actual sizes were always binary.
- Improved Cloud SDK integration, including improved error messages and instructions.
- The num_retries .boto configuration value now applies to all requests (previously it was ignored for JSON API requests).
- rsync now works with non-existent destination subdirectories.
- Raised the default resumable upload threshold from 2MB to 8MB to improve performance.
- Benign retry messages now print only when debug mode is enabled via the top-level -d flag.
- The top-level -q flag now suppresses suggestions to use the -m flag.
- Command synopsis is now output when the wrong number of arguments are provided.
- Removed dependency on google-api-python-client module, added dependencies on oauth2client and six modules.

- Fixed a perfdiag assumption that ipaddrlist was populated.
- Fixed an AttributeError when setting an invalid canned ACL with defacl set.
- Fixed a bug where non-resumable uploads would include payload in debug output when for running in debug mode (-D).
- Added the proxy_rdns configuration variable for clients that do DNS lookups via a proxy.

- Added DNS, connection latency, and proxy use information to perfdiag command.
- perfdiag command will not perform DNS lookups if they are disabled in boto config.
- perfdiag command will now only attempt to delete uploaded objects when running write tests.
- Added code coverage support to test command.
- rsync -d now succeeds on a 404 for a to-be-deleted object (for example, when the object was already deleted by an external process).
- Fixed a bug that caused resumable uploads to restart if gsutil was terminated with CTRL-C.
- Fixed a bug in defacl ch command that caused a failure when updating an existing default object ACL entry.
- Fixed an invalid literal bug during rsync file listing.
- Made several improvements to JSON upload stability, including fixing a bug which occasionally caused resumable upload hashes not to catch up properly.
- All JSON calls now have socket timeouts, eliminating hangs under flaky network conditions.
- Fixed a bug where acl ch -g AllAuthenticatedUsers would instead add AllUsers.
- Fixed a bug that caused object custom metadata not to be preserved when copying in the cloud.
- Fixed a bug where du -s did not properly elide subdirectories.
- Parallel composite uploads are now disabled by default until crcmod is available in major Linux distributions. To re-enable the setting from prior versions, in the [GSUtil] section of your .boto config file, add: parallel_composite_upload_threshold=150M
- Non-wildcarded URLs for existing objects now use Get before trying List (as in gsutil3), and thus are not subject to eventual listing consistency.
- gsutil -D now redacts proxy configuration values in the output.
- Added the hash command, which can calculate hashes of local files. gsutil already calculates hashes for integrity checking, but this allows the user to separately calculate the MD5 and CRC32c hashes of a local file.
- Many improvements to JSON API media transfers, including far more robust retry logic.
- Fixed "File changed during upload: EOF..." errors on XML resumable uploads.
- Fixed rsync command to read and write index files in binary mode.
- Fix potential TypeError in _CheckAndHandleCredentialException.
- Fixed possible data corruption when using JSON API uploads for small files with lines starting with "From:", which would cause integrity checks to fail.
- Fixed gsutil cp to skip directory placeholders when downloading, avoiding "directory exists where the file needs to be created" errors.
- Fixed daisy chain cp/rsync for files >= 100MB.
- Fixed a bug in JSON proxy support where the proxy info was sometimes unused.

- Improved object listing performance when using the XML API.
- Improved various error messages.
- Improved progress display during media transfer.
- Switched to truncated exponential backoff for retries.

- Added some information such as OS and Cloud SDK wrapping to gsutil version, and changed the output format to be more uniform.
- Daisy chain cp/rsync now supports resumable uploads.
- Improved proxy support for proxy username and passwords.
- x-amz headers are now supported for cp, rsync, and setmeta. x-amz-meta headers continue to be supported as well.
- Fix acl/defacl ch changing the role of an existing group.
- Fix unicode and 404 errors when using manifests.
- Fix parallelism configuration bug that limited gsutil rsync to two threads and could lead to rsync hangs. "gsutil -m rsync" runs much faster, and rsync uploads of large local files are now faster via parallel composite upload. Parallel composite uploads of large files are also faster.
- Fix rsync bug with parallel composite uploads.
- Fix TypeError that could occur when running the cp command with no credentials.
- Progress indicators for -m cp/rsync commands are now more readable.
- Added command being run to gsutil -d/-D output.
- Lowered default parallelism for 'gsutil -m test' and added hang detection.
- Added parallel test execution support to test command, ex: "gsutil -m test"
- Fix failure during retry of an XML download.
- Moved to boto release 2.29.1 fixing boto authentication erroneously reporting OAuth2 credentials as invalid.
- Fix parallel composite uploads when using only a single process and thread.
- Fix an invalid seek during daisy chain operation that affected file copy from Google Cloud Storage -> S3 for files greater than 8KB in size.
- Fix "gsutil acl ch" with AllUsers or AllAuthenticatedUsers groups.
- Fix some copy errors writing new lines to the manifest file.
- Fix "gsutil test" return code to properly be 0 on success.
- "gsutil cp -z" now ignores whitespace in the extension list.
- Fixed a bug in parallel composite uploads where uploads with existing components would fail.
- Moved gcs-oauth2-boto-plugin to version 1.5, fixing a bug in the PyPi gsutil distribution that would cause gsutil to unnecessarily attempt to query the Google Compute Engine metadata service.
- Parallel composite uploads no longer specify an if-not-match precondition when uploading component parts.
- Parallel composite uploads no longer calculate a CRC32c hash prior to uploading component parts (these are still validated by an MD5 hash).
- Removed apitools dependency on gflags.
- The Google Cloud Storage configuration data supported by the acl, cors, and lifecycle commands now uses the JSON format instead of the older XML format. gsutil 4.0 will fail and provide conversion instructions if an XML configuration file is provided as an argument for a gs:// URL.
- gsutil no longer accepts arbitrary headers via the global -h flag. Documented headers for gsutil commands are still supported; for the full list of supported headers, see "gsutil help command_opts".
- The compose command will now default the destination object's Content-Type to the Content-Type of the first source object if none is provided via the -h global flag.
- The long-deprecated -t and -q options have been removed from the cp command.
- The perfdiag command no longer supports adding a host header.
- Having OAuth2 User Account credentials and OAuth2 Service Account credentials configured simultaneously will now fail with an error message to avoid confusion. Also, a single invalid credential will fail with an error message. See "gsutil help creds" for details.
- Bucket relocate scripts have been removed.
- Downloading object names ending with '/' is no longer supported to avoid problems this caused for directores using the Google Cloud Console.
- rm -r now implies rm -ra (removing all object versions recursively).
- All commands using the global -m option or a force option (such as rm -f or cp -c) will now return a non-zero exit code if there are any failures during the operation.
- MD5 and CRC32c values are now represented in base64 encoding instead of hex encoding (this includes manifest files).
- The Google Cloud Storage JSON API (v1) is now the default API used by gsutil for all commands targeting gs:// URLs. The JSON API is more bandwidth efficient than the older XML API when transferring metadata and does not require separate calls to preserve object ACLs when copying. The XML API will automatically be used when accessing s3:// URLs.
- The Google Cloud Storage XML API can be used in lieu of the JSON API by setting 'prefer_api = xml' in the GSUtil section of your boto config file.
- Added the rsync command that can synchronize cloud and local directories.
- Added the signurl command that can generate Google Cloud Storage signed URLs.
- The perfdiag command now supports a listing latency test.
- The rb command now supports a -f flag allowing it to continue when errors are encountered.
- The test command now supports a -s flag that runs tests against S3.
- All python files not under a third_party directory are now pylint-clean, with the exception of TODO-format and a handful of warnings in root-level files. As part of the de-linting process, many edge-case bugs were identified and fixed.
- The ls command now operates depth-first (as in Unix ls) instead of breadth-first.
- Daisy-chain copying does not currently support resumable uploads.
- Several compatibility improvements for Windows and S3.
- Fixed potential bug with update command on CentOS.
- Changes to protect security of resumable upload IDs.

- Changed ConfigureNoOpAuthIfNeeded logic so we configure no-op auth plugin even if there is a config_file list, since GCE always configures /etc/boto.cfg, even if user has no storage scopes configured.
- Additional changes: a. Removed assertion of oauth access token cache check log from test_Doption.py, which may not be true sometimes (e.g., if user is using HMAC creds). b.

- Fixed ISO 639.1 ref in config command help text
- Fixed bug where gsutil cp -D didn't preserve metadata
- Fixed problem where gsutil -m is hard to interrupt (partial fix for issue #99 - only for Linux/MacOS; problem still exists for Windows).
- Fixed broken reference to boto_lib_dir in update command.
- Made changing ACL not retry on 400 error.
- Fixed name expansion bug for case where uri_strs is itself an iterator (issue #131); implemented additional naming unit test for this case.

- Removed .pyc files from tarball/zipfile.
- Added new root certs to cacerts.txt, to provide additional flexibility in the future.
- Fixed two version-specific URI bugs:
-
gsutil cp -r gs://bucket1 gs://bucket2 would create objects in bucket2 with names corresponding to version-specific URIs in bucket1 (e.g., gs://bucket2/obj#1361417568482000, where the "#1361417568482000" part was part of the object name, not the object's generation).
This problem similarly caused gsutil cp -r gs://bucket1 ./dir to create files names corresponding to version-specific URIs in bucket1.
-
gsutil rm -a gs://bucket/obj would attempt to delete the same object twice, getting a NoSuchKey error on the second attempt.
-
- Fixed bug that caused attempt to dupe-encode a unicode filename.
- Refactored retry logic from setmeta and chacl to use @Retry decorator.
- Moved @Retry decorator to third_party.
- Fixed flaky tests.
- Make version-specific URI parsing more robust. This fixes a bug where listing buckets in certain cases would result in the error 'BucketStorageUri' object has no attribute 'version_specific_uri'
- Implemented new chacl command, which makes it easy to add and remove bucket and object ACL grants without having to edit XML (like the older setacl command).
- Implemented new "daisy-chain" copying mode, which allows cross-provider copies to run without buffering to local disk, and to use resumable uploads. This copying mode also allows copying between locations and between storage classes, using the new gsutil cp -D option. (Daisy-chain copying is the default when copying between providers, but must be explicitly requested for the other cases to keep costs and performance expectations clear.)
- Implemented new perfdiag command to run a diagnostic test against a bucket, collect system information, and report results. Useful when working with Google Cloud Storage team to resolve questions about performance.
- Added SIGQUIT (^) handler, to allow breakpointing a running gsutil.
-
Fixed bug where gsutil setwebcfg signature didn't match with HMAC authentication.
-
Fixed ASCII codec decode error when constructing tracker filename from non-7bit ASCII input filename.
-
Changed boto auth plugin framework to allow multiple plugins supporting requested capability, which fixes gsutil exception that used to happen where a GCE user had a service account configured and then ran gsutil config.
-
Changed Command.Apply method to be resilient to name expansion exceptions. Before this change, if an exception was raised during iteration of NameExpansionResult, the parent process would immediately stop execution, causing the _EOF_NAME_EXPANSION_RESULT to never be sent to child processes. This resulted in the process hanging forever.
-
Fixed various bugs for gsutil running on Windows:
- Fixed various places from a hard-coded '/' to os.sep.
- Fixed a bug in the cp command where it was using the destination URI's .delim property instead of the source URI.
- Fixed a bug in the cp command's _SrcDstSame function by simplifying it to use os.path.normpath.
- Fixed windows bug in tests/util.py _NormalizeURI function.
- Fixed ZeroDivisionError sometimes happening during unit tests on Windows.
-
Fixed gsutil rm bug that caused exit status 1 when encountered non-existent URI.
-
Fixed support for gsutil cp file -.
-
Added preconditions and retry logic to setmeta command, to enforce concurrency control.
-
Fixed bug in copying subdirs to subdirs.
-
Fixed cases where boto debug_level caused too much or too little logging:
- resumable and one-shot uploads weren't showing response headers when connection.debug > 0.
- payload was showing up in debug output when connection.debug < 4 for streaming uploads.
-
Removed XML parsing from setacl. The previous implementation relied on loose XML handling, which could truncate what it sends to the service, allowing invalid XML to be specified by the user. Instead now the ACL XML is passed verbatim and we rely on server-side schema enforcement.
-
Added user-agent header to resumable uploads.
-
Fixed reporting bits/s when it was really bytes/s.
-
Changed so we now pass headers with API version & project ID to create_bucket().
-
Made "gsutil rm -r gs://bucket/folder" remove xyz_$folder$ object (which is created by various GUI tools).
-
Fixed bug where gsutil binary was shipped with protection 750 instead of 755.
-
Reworked versioned object handling:
- Removed need for commands to specify -v option to parse versions. Versioned URIs are now uniformly handled by all commands.
- Refactored StorageUri parsing that had been split across storage_uri and convenience; made versioned URIs render with version string so StorageUri is round-trippable (boto change).
- Implemented gsutil cp -v option for printing the version-specific URI that was just created.
- Added error detail for attempt to delete non-empty versioned bucket. Also added versioning state to ls -L -b gs://bucket output.
- Changed URI parsing to use pre-compiled regex's.
- Other bug fixes.
-
Rewrote/deepened/improved various parts of built-in help:
- Updated 'gsutil help dev'.

- Changed cp tests that don't specify a Content-Type to check for new binary/octet-stream default instead of server-detected mime type.
-
Changed gsutil mv to allow moving local files/dirs to the cloud. Previously this was disallowed in the belief we should be conservative about deleting data from local disk but there are legitimate use cases for moving data from a local dir to the cloud, it's clear to the user this would remove data from the local disk, and allowing it makes the tool behavior more consistent with what users would expect.
-
Changed gsutil update command to insist on is_secure and https_validate_certificates.
-
Fixed release no longer to include extraneous boto dirs in top-level of gsutil distribution (like bin/ and docs/).

- Added support for Windows drive letter-prefaced paths when using Storage URIs.
- Fixed performance bug when downloading a large object with Content- Encoding:gzip, where decompression attempted to load the entire object in memory. Also added "Uncompressing" log output if file is larger than 50M, to make it clear the download hasn't stalled.

- Fixed bug where tracker file included a timestamp that caused it not to be recognized across sessions.
- Fixed bug where gs://bucket/*/dir wildcard matches too many objects.
- Fixed documentation errors in help associated with ACLs and projects.
- Changed GCS ACL parsing to be case-insensitive.
- Changed ls to print error and exit with non-0 status when wildcard matches nothing, to be more consistent with UNIX shell behavior.
- Fixed problem where resumable uploads/downloads of objects with very long names would generate tracking files with names that exceeded local file system limits, making it impossible to complete resumable transfers for those objects. Solution was to build the tracking file name from a fixed prefix, SHA1 hash of the long filename, epoch timestamp and last 16 chars of the long filename, which is guarantee to be a predictable and reasonable length.
- Fixed minor bug in output from 'gsutil help dev' which advised executing an inconsequential test script (test_util.py).
- Fixed problem where gsutil ver and debug flags crashed when used with newly generated boto config files.
- Fixed gsutil bug in windows path handling, and make checksumming work across platforms.
- Fixed enablelogging to translate -b URI param to plain bucket name in REST API request.
- Fixed problem where gsutil didn't convert between OS-specific directory separators when copying individually-named files (issue 87).
- Fixed problem where gsutil ls -R didn't work right if there was a key with a leading path (like /foo/bar/baz)
- Removed erroneous setting of Content-Encoding when a gzip file is uploaded (vs running gsutil cp -z, when Content-Encoding should be set). This error caused users to get gsutil.tar.gz file uncompressed by the user agent (like wget) while downloading, making the file appear to be of the wrong size/content.
- Fixed handling of gsutil help for Windows (previous code depended on termios and fcntl libs, which are Linux/MacOS-specific).
-
Backwards-incompatible wildcard change: The '*' wildcard now only matches objects within a bucket directory. If you have scripts that depend on being able to match spanning multiple directories you need to use '**' instead. For example, the command:
gsutil cp gs://bucket/*.txtwill now only match .txt files in the top-level directory.
gsutil cp gs://bucket/**.txtwill match across all directories.
-
gsutil ls now lists one directory at a time. If you want to list all objects in a bucket, you can use:
gsutil ls gs://bucket/**or:
gsutil ls -R gs://bucket
-
Built-in help for all commands and many additional topics. Try "gsutil help" for a list of available commands and topics.
-
A new hierarchical file tree abstraction layer, which makes the flat bucket name space look like a hierarchical file tree. This makes several things possible:
- copying data to/from bucket sub-directories (see “gsutil help cp”).
- distributing large uploads/downloads across many machines (see “gsutil help cp”)
- renaming bucket sub-directories (see “gsutil help mv”).
- listing individual bucket sub-directories and for listing directories recursively (see “gsutil help ls”).
- setting ACLs for objects in a sub-directory (see “gsutil help setacl”).
-
Support for per-directory (*) and recursive (**) wildcards. Essentially, ** works the way * did in previous gsutil releases, and * now behaves consistently with how it works in command interpreters (like bash). The ability to specify directory-only wildcards also enables a number of use cases, such as distributing large uploads/downloads by wildcarded name. See "gsutil help wildcards" for details.
-
Support for Cross-Origin Resource Sharing (CORS) configuration. See "gsutil help cors" for details.
-
Support for multi-threading and recursive operation for setacl command (see “gsutil help setacl”).
-
Ability to use the UNIX 'file' command to do content type recognition as an alternative to filename extensions.
-
Introduction of new end-to-end test suite.
-
The gsutil version command now computes a checksum of the code, to detect corruption and local modification when assisting with technical support.
-
The gsutil update command is no longer beta/experimental, and now also supports updating from named URIs (for early/test releases).
-
Changed gsutil ls -L to also print Content-Disposition header.
- The gsutil cp -t option previously didn't work as documented, and instead Content-Type was always detected based on filename extension. Content-Type detection is now the default, the -t option is deprecated (to be removed in the future), and specifying a -h Content-Type header now correctly overrides the filename extension based handling. For details see "gsutil help metadata".
- Fixed bug that caused multi-threaded mv command not to percolate failures during the cp phase to the rm phase, which could under some circumstances cause data that was not copied to be deleted.
- Fixed bug that caused gsutil to use GET for ls -L requests. It now uses HEAD for ls -L requests, which is more efficient and faster.
- Fixed bug that caused gsutil not to preserve metadata during copy-in-the-cloud.
- Fixed bug that prevented setacl command from allowing DisplayName's in ACLs.
- Fixed bug that caused gsutil/boto to suppress consecutive slashes in path names.
- Fixed spec-non-compliant URI construction for resumable uploads.
- Fixed bug that caused rm -f not to work.
- Fixed UnicodeEncodeError that happened when redirecting gsutil ls output to a file with non-ASCII object names.
- UserAgent sent in HTTP requests now includes gsutil version number and OS name.
- Starting with this release users are able to get individual named releases from version-named objects: gs://pub/gsutil_.tar.gz and gs://pub/gsutil_.zip. The version-less counterparts (gs://pub/gsutil.tar.gz and gs://pub/gsutil.zip) will contain the latest release. Also, the gs://pub bucket is now publicly readable (so, anyone can list its contents).
-
Support for for two new installation modes: enterprise and RPM. Customers can now install gsutil one of three ways:
- Individual user mode (previously the only available mode): unpacking from a gzipped tarball (gs://pub/gsutil.tar.gz) or zip file (gs://pub/gsutil.zip) and running the gsutil command in place in the unpacked gsutil directory.
- Enterprise mode (new): unpacking as above, and then running the setup.py script in the unpacked gsutil directory. This allows a systems administrator to install gsutil in a central location, using the Python distutils facility. This mode is supported only on Linux and MacOS.
- RPM mode (new). A RedHat RPM can be built from the gsutil.spec.in file in the unpacked gsutil directory, allowing it to be installed as part of a RedHat build.
-
Note: v2.0 is the first numbered gsutil release. Previous releases were given timestamps for versions. Numbered releases enable downstream package builds (like RPMs) to define dependencies more easily. This is also the first version where we began including release notes.
