This page describes the process of switching to Hg, who's going to do what, and when.

KaiRo has done most of the changes to the build system, including setting up a test repo. See this page for the details of how to do a build using the test repository.

Before we all switch to using those instructions (using a new repo, not the one in that page), the following needs to happen:

• Announce plan to m.d.a.t, m.d.a.sm, m.d.a.c, m.d.planning (david/dmose/kairo, whenever this page is ready)
  • Dan's post

• Close CVS tree (KaiRo: Tuesday, 5AM Pacific)
  • TREE CLOSED: 5:10 AM

• Tag CVS files to import with HG_COMM_INITIAL_IMPORT (KaiRo, just before populating comm-central with that revision)
  • Tag: HG_COMM_INITIAL_IMPORT
  • Applied to: mozilla/directory/xpcom/ mozilla/mailnews/ mozilla/mail/ mozilla/suite/ mozilla/other-licenses/branding/thunderbird/
  • Date: 2008-07-22 5:17 AM approx

• populate new Hg repo (http://hg.mozilla.org/comm-central) with current copy of files from CVS trunk, land patches of bug 444686 there, ensure build(s) works (KaiRo, Tuesday, after the tree closes)
  • How Long: KaiRo expects 1 hour or less to get code there and apply the build system/patches so it should build.
  • Complete, local builds set off at 05:36 AM

• finalise docs, comments welcome.
  • Standard8 has posted these and links to them:
  • Comm-central source code (Mercurial)
  • comm-central
  • How comm-central's build system works

• Get SeaMonkey builder+nightly buildbots working off Hg (KaiRo, as soon as all code is in the repo)
  • Complete: builders cycle, nightlies from hg are there, auto-update works.
  • Builds fail when mozilla-central triggers build

• Get SeaMonkey unit test buildbots working off Hg (KaiRo, once builder+nightly boxes are spinning their first builds)
  • Basically working, but showing failures, not clear if they trigger correctly on checkin
  • Builds fail when mozilla-central triggers build
  • Current Problems:
    • bug 446678 chrome tests crash on Linux and Mac, fail on Windows
    • mochichrome tests leak memory (all platforms).
    • bug 446692 TUnit tests fail on Windows (same as TB failures)
    • TUnit 1 test fails on Mac (test_punycodeURIs.js) - needs investigation
    • reftest one test fails on Mac - need investigation

• Get Thunderbird unit test buildbots working off of Hg (gozer)
  • buildbots not respinning on check-in (to comm-central or mozilla-central)
  • bug 446692 TUnit tests fail on Windows (same as SM failures)
  • TUnit Linux failure similar to gconf error seen before - gozer to fix
    • bug 444818 is back, and something in the new build system wipes local tree changes, so it would be better if the suggested patch could land soon.
  • TUnit Mac, one failure in test_nsIMsgFolderListenerLocal.js, possible timeout - Standard8 couldn't reproduce, new build set going. gozer: definitely timing related, as playing with the timeout value makes the bug appear/dissapear. I've seen the test pass with a timeout of 6s.
  • Windows build continuously failing.
  • Builds fail when mozilla-central triggers build

• Get Thunderbird nightlies working off of Hg (gozer) bug 447629
  • tb-linux-tbox is running a buildbot slave
  • bm-xserve07 is running a buildbot slave
  • tbnewref-win32-tbox is running a buildbot slave
  • Builds fail when mozilla-central triggers build

• open Hg tree (who? when?) and note document updates.
  • KaiRo, davida, dmose or gozer should be able to do this from a tinderbox message aspect.
