Zimbra is in the process of transitioning between source code repositories at the moment. The current Perforce/Git setup has been less than ideal and so we are working on moving off of that setup. As part of the transition, we are also working to reorganize the single large repository into a series of smaller, component focused repositories. This process will take a bit of time and we want to make sure everything works as expected once complete. We are using internally hosted git repositories as a staging area before making all of the repositories available via GitHub.
Breaking the single repository up has been the largest area of work and, as you might imagine, has a significant impact on the build process. I have asked the team to hold back publishing the repositories until the build system has been updated to work with the new repository layout and git in general. We are working through these issues and expect to have code making its way to GitHub in the next few weeks.
Once completed, the entire Zimbra source code will be available via a set of repositories on GitHub. This should make it much easier to work with the code base and provide some much needed separation of the code components. I know it is a bit inconvenient with respect to work that is occurring right now, but we want to make sure things are done right.
This is a project I have been wanting the team to undertake for well over a year now, and we are finally close to the end. The result will be a much more accessible code base as well as the introduction of a 'sane' branching strategy. Stay tuned for additional updates and I appreciate your patience as we begin rolling the new repositories out.
