ReleaseEngineering/Archive/Enable or Disable Updates on Aurora

When Nightly merges into Aurora every 6 weeks we lock Aurora updates at a specific old version for a period of time (days to a week) while QA runs some tests. Once their tests have passed, we re-enable updates. We're also occaisonly asked to disable updates temporarily for other reasons. This document describes how to do both of these things.

Note the magic rule ids below. These correspond to ids of rows in the "rules" table of Balrog. If we fix bug 1067402 we can pass more intelligable values here.

Disabling Updates

NOTE: Disabling no longer has to be done by hand during uplifts. The uplift script does it. As cltbld@buildbot-master81:

cd /home/cltbld/
rm -rf tools
hg clone https://hg.mozilla.org/build/tools
cd tools/scripts/updates
# Run with dry run first, sanity check the "Would've locked" lines.
python2.7 balrog-nightly-locker.py -a https://aus4-admin.mozilla.org -c /builds/buildbot/build_scheduler/master/BuildSlaves.py -u ffxbld -r 8 -r 10 -r 18 -n lock
# Run without dry run to lock the updates
python2.7 balrog-nightly-locker.py -a https://aus4-admin.mozilla.org -c /builds/buildbot/build_scheduler/master/BuildSlaves.py -u ffxbld -r 8 -r 10 -r 18 lock

This will eventually be integrated with the merge day script.

Enabling Updates

Unlike disabling, Firefox and Fennec aren't always re-enabled at the same time.

Fennec

As cltbld@buildbot-master81:

cd /home/cltbld/
rm -rf tools
hg clone https://hg.mozilla.org/build/tools
cd tools/scripts/updates
# Run with dry run first, sanity check the "Would've unlocked" lines.
python2.7 balrog-nightly-locker.py -a https://aus4-admin.mozilla.org -c /builds/buildbot/build_scheduler/master/BuildSlaves.py -u ffxbld -r 8 -n unlock
# Run without dry run to unlock the updates
python2.7 balrog-nightly-locker.py -a https://aus4-admin.mozilla.org -c /builds/buildbot/build_scheduler/master/BuildSlaves.py -u ffxbld -r 8 unlock

Firefox

As cltbld@buildbot-master81:

cd /home/cltbld/
rm -rf tools
hg clone https://hg.mozilla.org/build/tools
cd tools/scripts/updates
# Run with dry run first, sanity check the "Would've unlocked" lines.
python2.7 balrog-nightly-locker.py -a https://aus4-admin.mozilla.org -c /builds/buildbot/build_scheduler/master/BuildSlaves.py -u ffxbld -r 10 -r 18 -n unlock
# Run without dry run to unlock the updates
python2.7 balrog-nightly-locker.py -a https://aus4-admin.mozilla.org -c /builds/buildbot/build_scheduler/master/BuildSlaves.py -u ffxbld -r 10 -r 18 unlock
