#pragma page-filename DEV/versions/9 = Mailman Developer Resources = Thank you for contributing to Mailman! Please also see the [[../../Mailman3|Mailman 3]] release notes. This year we will be applying to Google's [[https://summerofcode.withgoogle.com/|Summer of Code]]. For information about Mailman's project ideas, click here: [[DEV/Google Summer of Code 2023|Google Summer of Code 2023]]. == How to get started == Please read the [[../HowToContributeGit| git quickstart]] before doing anything else! The [[../SetupDevEnvironment|Setup instructions]] will guide you through the process of setting up all the projects so you can start developing. == Contributing to Mailman, step 1: Git and Gitlab == Mailman 3's source code is published in [[http://git-scm.com/|git]]. Project management is available on [[https://gitlab.com/mailman/mailman|Gitlab]]. We switched from Bazaar on Launchpad on May 4th, 2015. Previous to that, we switched from Subversion on !SourceForge on June 22, 2007. '''Please note:''' Mailman 2.1 development continues to be hosted in Bazaar on [[../MailmanOnLaunchpad|Launchpad]]. For now, the Mailman 3 branch on Launchpad will continue to be available in read-only mode. == Contributing to Mailman, step 2: Contribution workflow process == 1. A developer has an idea for an enhancement.  They discuss it on the [[http://mail.python.org/mailman/listinfo/mailman-developers|mailman-developers]] mailing list. For higher bandwidth discussions we can use irc (#mailman channel on [[irc://libera.chat|irc://libera.chat]]). 1. Developers can clone our git repository, push their own branches, and submit [[https://gitlab.com/mailman/mailman/merge_requests|a merge request]] against the official branches. 1. If the idea is appropriate for GNU Mailman and we decide to include it, FSF must get copyright assignments from the developer. See below. Do this early, since it can take some time to get all the paperwork to the FSF. == Branch development guidelines == * Branches should be self-contained:  Include documentation, a NEWS entry, and tests.  Ideally, there would be one bug for every branch. * Be sure your branch does not provoke any regressions. Run {{{tox}}} on your branch and be sure everything passes. Eventually, we'll enable CI on Gitlab so you'll know immediately whether your branch is ready for merging. * Branches should be as small as possible. The smaller the branch the easier it is to review. == Contributing to Mailman, step 3: Copyright assignment == Mailman is a [[http://www.gnu.org|GNU]] project with the majority of the copyrights being held by the [[http://www.fsf.org|Free Software Foundation]]. We therefore request that developers who contribute code, assign their copyrights in their Mailman contribution to the FSF. To do this, you first need to submit a [[../GNU copyright assignment request form|GNU copyright assignment request form]] containing some basic information, and then fill out the form that the FSF sends you. Please [[mailto:mailman-cabal@python.org|let us know]] after you've sent the second form so that we can track your contribution. The FSF often doesn't tell us in a timely manner when such forms have been received. == Version-specific resources == Mailman's developers are currently focused mostly on working towards the release of Mailman 3.0. * [[../Mailman 2.1|Mailman 2.1]] * [[../Mailman 2.2|Mailman 2.2]] -- 2.1 is the stable branch, now in maintenance mode * [[../Mailman 3.0|Mailman 3.0]] -- 3.0 is the stable Mailman 3 release * [[../Mailman 3.1|Mailman 3.1]] * [[../Mailman 3.2|Mailman 3.2]] == Sprints == * [[../Google_Summer_of_Code_2015|Google Summer of Code 2015]] * [[../PyCon 2015 Sprint|PyCon 2015 Sprint]] * [[../Google Summer of Code 2014|Google Summer of Code 2014]] * [[../PyCon 2014 Sprint|PyCon Sprint 2014]] * [[../Google Summer of Code 2013|Google Summer of Code 2013]] * [[../PyCon Sprint 2013|PyCon Sprint 2013]] * [[../Google Summer of Code 2012|Google Summer of Code 2012]] * [[../Google Summer of Code 2011|Google Summer of Code 2011]] * [[http://wiki.list.org/display/DEV/GHC12+Open+Source+Day+Hackathon|GHC12 Open Source Day Hackathon]] * [[../Google Summer of Code 2011|Google Summer of Code 2011]] * [[../PyCon Sprint 2010|PyCon Sprint 2010]] * [[../PyCon Sprint 2009|PyCon Sprint 2009]] * [[../Google Summer of Code 2008|Google Summer of Code 2008]] * [[../Google_Summer_of_Code_2006|Google Summer of Code 2006]] == Initiatives, proposals, ideas == * [[../New Logos|New Logos]] * [[../GPLv3|GPLv3]] * [[../Internationalization|Internationalization]] * [[../DKIM|DKIM]] and [[../DMARC|DMARC]] * [[../OpenID|OpenID]] * [[../MemberAdaptor Semantics|MemberAdaptor Semantics]] * [[../Improved Logging|Improved Logging]] * [[../Stable URLs|Stable URLs]] * [[../Patches|Patches]] * [[../ReplyTo|ReplyTo]] * [[../Usability|Usability]] * [[../ModernArchiving|Modern Archiving]] (currently HyperKitty in [[../Mailman 3.0|Mailman 3]]) * [[../Postorius Web Interface|Postorius Web Interface]] (in [[../Mailman 3.0|Mailman 3]]) * [[../REST Interface|REST Interface]] (a part of [[../Mailman 3.0|Mailman 3]] core) * [[http://blog.linuxgrrl.com/2012/03/14/mailman-brainstorm-2/|Mairin Duffy's blog ideas]] == Suggestions == People seem to have trouble figuring out where to make suggestions or feature requests.
