Showstoppers for H4 Release

The decisions made for Horde 4 so far are:

  • Move to git for future (Horde 4+) version control. Code will be pushed to a clean git repository as it is modified for Horde 4 and PHP 5. Git pushes will generate email to a new list, commits@lists.horde.org. Everything currently in CVS will remain available, and Horde 3.x will continue to be developed in and released from the existing CVS structure.
  • Aim for shorter release cycles of major versions. When backwards compatibility is broken we will increment the major version number (Horde 3 to Horde 4) as we do now; we'll just do that more often. Feedback indicates that being able to do feature upgrades of an application but not Horde, or vice versa, is not a big advantage for most people.
  • Use individual package versions much more extensively with Horde 4. We want it to be possible to release an application upgrade that relies on new framework functionality without requiring a new major version; instead, many changes will be possible by just requiring a specific package version.
  • Finally, and most importantly, we will be focusing on getting the last Horde 3.3 releases out (see above), and then shifting our major focus to Horde 4. Our goal is to have an initial release of Horde 4.0 within 6 months of starting serious development on it; and to aim for major version releases approximately every year thereafter.

Mini-FAQ for Horde 4 development

Q: Are we going to keep the existing development model where we have a "master" server (i.e. cvs.horde.org) where we will build the releases? For our workflow, that seems to make the most sense - since we don't have a "master" user that checks all commits before integrating.

A: Yes. All HEAD commits are pushed to dev.horde.org:/horde/git/horde (or horde-support, etc.), and we'll use branches to do local dev or to coordinate non-mainline work.

Q: How do I start from scratch with a Git install

A: See http://www.horde.org/source/git.php

Q: Why does the sidebar not collapse/Why can't I switch tabs on the config screen/Why do certain links not work?

A: Make sure your 'jsfs' and 'jsuri' entries in horde/config/registry.php are correct. They are actually no needed anymore at all, unless you really know what you are doing. Applications no longer come shipped with javascript source files in js/src - they all live directly under js/ now.
