Apache CouchDB DEVELOPERS

Before you start here, read INSTALL.Unix (or INSTALL.Windows) and follow the setup instructions including the installation of all the listed dependencies for your system.

Only follow these instructions if you are building from a source checkout.

If you're unsure what this means, ignore this document.

Dependencies

You need the following to run tests:

You need the following optionally to build documentation:

You need the following optionally to build releases:

You need the following optionally to build Fauxton:

You will need these optional dependencies installed if:

  • You are working on the documentation, or
  • You are preparing a distribution archive

However, you do not need them if:

  • You are building from a distribution archive, or
  • You don't care about building the documentation

If you intend to build Fauxton, you will also need to install its dependencies. After running ./configure to download all of the dependent repositories, you can read about required dependencies in src/fauxton/readme.md. Typically, installing npm and node.js are sufficient to enable a Fauxton build.

Here is a list of optional dependencies for various operating systems. Installation will be easiest, when you install them all.

Debian-based (inc. Ubuntu) Systems

sudo apt-get install help2man python-sphinx gnupg nodejs npm \
     python3 python3-venv

Gentoo-based Systems

sudo emerge gnupg coreutils pkgconfig help2man sphinx python
sudo pip install hypothesis requests nose

Centos 7 and RHEL 7

sudo yum install help2man python-sphinx python-docutils \
    python-pygments gnupg nodejs npm

Mac OS X

Install Homebrew, if you do not have it already.

Unless you want to install the optional dependencies, skip to the next section.

Install what else we can with Homebrew:

brew install help2man gnupg md5sha1sum node python

If you don't already have pip installed, install it:

sudo easy_install pip

Now, install the required Python packages:

sudo pip install sphinx docutils pygments sphinx_rtd_theme

FreeBSD

pkg install help2man gnupg py27-sphinx node
pip install nose requests hypothesis

Windows

Follow the instructions in INSTALL.Windows and build all components from source, using the same Visual C++ compiler and runtime.

Configuring

Configure the source by running:

./configure

If you intend to run the test suites:

./configure -c

If you don't want to build Fauxton or documentation specify --disable-fauxton and/or --disable-docs arguments for configure to ignore their build and avoid any issues with their dependencies.

See ./configure --help for more information.

Testing

To run all the tests use run:

make check

You can also run each test suite individually via eunit and javascript targets:

make eunit
make javascript

If you need to run specific Erlang tests, you can pass special "options" to make targets:

# Run tests only for couch and chttpd apps
make eunit apps=couch,chttpd

# Run only tests from couch_btree_tests suite
make eunit apps=couch suites=couch_btree

# Run only only specific tests
make eunit tests=btree_open_test,reductions_test

# Ignore tests for specified apps
make eunit skip_deps=couch_log,couch_epi

The apps, suites, tests and skip_deps could be combined in any way. These are mimics to rebar eunit arguments. If you're not satisfied by these, you can use EUNIT_OPT environment variable to specify exact rebar eunit options:

make eunit EUNIT_OPTS="apps=couch,chttpd"

JavaScript tests accepts only suites option, but in the same way:

# Run all JavaScript tests
make javascript

# Run only basic and design_options tests
make javascript suites="basic design_options"

# Ignore specific test suites via command line
make javascript ignore_js_suites="all_docs bulk_docs"

# Ignore specific test suites in makefile
ignore_js_suites=all_docs,bulk_docs

Note that tests on the command line are delimited here by whitespace, not by comma.You can get list of all possible test targets with the following command:

make list-js-suites

Code analyzer could be run by:

make dialyze

If you need to analyze only specific apps, you can specify them in familiar way

make dialyze apps=couch,couch_epi

See make help for more info and useful commands.

Please report any problems to the developer's mailing list.

Releasing

The release procedure is documented here:

https://cwiki.apache.org/confluence/display/COUCHDB/Release+Procedure

Unix-like Systems

A release tarball can be built by running:

make dist

An Erlang CouchDB release includes the full Erlang Run Time System and all dependent applications necessary to run CouchDB, standalone. The release created is completely relocatable on the file system, and is the recommended way to distribute binaries of CouchDB. A release can be built by running:

make release

The release can then be found in the rel/couchdb directory.

Microsoft Windows

The release tarball and Erlang CouchDB release commands work on Microsoft Windows the same as they do on Unix-like systems. To create a full installer, the separate couchdb-glazier repository is required. Full instructions are available in that repository's README file.
