This file contains information for those wishing to modify IMAPClient and contribute back to the project.
The official source code repository for IMAPClient can be found on bitbucket at: https://bitbucket.org/mjs0/imapclient/
Any major feature branches will also be found on bitbucket as forks of this repository.
[Note that the branching scheme discussed here started to be used as of the 0.9.2 release of IMAPClient]
The project uses two named branches: default and stable. New feature development will always happen on the default branch.
The stable branch will always reflect the last released version. Small bug fixes to the stable release will occur on this branch and should be merged back in the the default branch.
Releases will always be created from the stable branch. Before a major release changes will be merged from the default branch to the stable branch.
This branching approach is used by various projects including the Mercurial project. See this blog article for more information: http://stevelosh.com/blog/2010/05/mercurial-workflows-stable-default/
Each released version is available in the IMAPClient repository as a Mercurial tag (e.g. "0.9.1"). Release tags will always be created on the stable branch (as described above).
There are comprehensive unit tests for the server response parser and a number of other parts of the code. These tests use the unittest2 package which is also included as the standard unittest package in Python 2.7 and 3.2 onwards.
To run the tests run:
python setup.py test
from the root of the package source. This will install the Mock package (locally) if it isn't already installed as it is required for many of the tests.
Where unittest2 is included in the standard library (eg. Python 2.7 and 3.2) you can also run all unit tests like this (from the root directory of the IMAPClient source):
python -m unittest discover
Alternatively, if unittest2 is installed separately use the unit2 script (for Unix-like systems) or the unit2.py script:
unit2 discover unit2.py discover
It is possible to run the unit tests against all supported Python
versions at once using tox. Once installed, the tox command
will use the tox.ini file in the root of the source directory and run
the unit tests against the Python versions officially supported by
IMAPClient.
The best way to contribute changes to IMAPClient is to fork the official repository on bitbucket, make changes to your personal fork and then submit a pull request.
Discussion on the mailing list before undertaking development is highly encouraged for potentially major changes.
Although not essential, it will make the project maintainer a much happier person if change submissions include appropriate updates to unit tests and the live tests. Please ask if you're unsure how of how the tests work.
