2.0.0.20 to 3.0.9

Generate Major Update Snippets

These are for the "vanilla" builds we're going to update.

Update these config files

  • CVS:mozilla/tools/patcher-configs/moz18-branch-major-update-patcher2.cfg
  • HG: build/tools/release/updates/moz18-firefox-{linux,mac,win32}-major.cfg

with review as usual.

Then generate the snippets

# ssh cltbld@production-prometheus-vm.build.mozilla.org
mkdir -p /builds/2.0.0.20-3.0.9-major-update/snippets
cd /builds/2.0.0.20-3.0.9-major-update/snippets

cd temp/firefox
ln -s 3.0.9 2.0.0.20-3.0.9
cd ../..

# Create partial patches and snippets
./patcher2.pl --create-patches --app=firefox --config=../patcher-configs/moz18-branch-major-update-patcher2.cfg 2>&1 | tee ../firefox-create-patches.log

Separate out beta snippets

cd temp/firefox/2.0.0.20-3.0.9
rsync -a aus2/ aus2.beta/
find aus2.beta/ -type d -name "release" -exec rm -rfv {} \;
find aus2/ -type d -name "beta" -exec rm -rfv {} \; 

Quick verify

This has changed a bit from last time because we haven't shipped 3.0.9 yet. Therefore we have to do QA using betatest pointing at the candidates dir, then 3.0.9 ships and we later go to beta (using bouncer), and later still enable the release channel (bouncer again). So we want releasetest == beta == release and accept that betatest is different.

# releasetest == beta
find aus2.test -type d -iregex '.*releasetest.*' | perl -nle '$a = $_; $a =~ s/releasetest/beta/; $a =~ s/aus2\.test/aus2.beta/; system("diff -r -u $_ $a");'
find aus2.beta -type d -iregex '.*/beta$' | perl -nle '$a = $_; $a =~ s/beta$/releasetest/; $a =~ s/aus2\.beta/aus2.test/; system("diff -r -u $_ $a");'

# releasetest == release
find aus2.test -type d -iregex '.*releasetest.*' | perl -nle '$a = $_; $a =~ s/releasetest/release/; $a =~ s/aus2\.test/aus2/; system("diff -r -u $_ $a");'
find aus2 -type d -iregex '.*/release$' | perl -nle '$a = $_; $a =~ s/release$/releasetest/; $a =~ s/aus2/aus2.test/; system("diff -r -u $_ $a");'

No differences found.

Update verify

Ran update verify on fx-{linux,mac,win32}-1.9-slave2 as follows:

mkdir -p /builds/verify/firefox-20020-309-major/
cd /builds/verify/firefox-20020-309-major/
hg clone http://hg.mozilla.org/build/tools/

# get patch to trawl "Only in" directories
cd tools/release/common
# on mac & linux
curl -sL https://bugzilla.mozilla.org/attachment.cgi?id=367544 | patch -p3

patch -p3 < patch

# everyone ...

cd ../updates
./verify.sh -c moz18-firefox-$platform-major.cfg 2>&1 | tee $platform.log

Logs look fine, and unchanged from last time. Each platform has some standard differences, here's Linux

  • The channel-prefs.js is a harmless comment change due the path on the build machine changing and us exlicitly not including that file in the complete mar
  • extensions/{inspector@mozilla.org,talkback@mozilla.org} are trees of empty dirs. We've removed all the files but the updater can't remove dirs (for safety), no problem because the Addons manager does that for us
  • Some locales also give messages like (eg be), due to them removing those plugins from the 3.0 build but we can't remove them for only some locales. Better user experience if the stuff you use is not vanished anyway

Update verify on releasetest

As we're using files in different locations, verify releasetest (same as beta) snippets are OK on fx-{linux,mac,win32}-1.9-slave2:

cd /builds/verify/firefox-20020-309-major/tools/release/updates
platform=linux   # or mac or win32
# modify moz18-firefox-$platform-major.cfg:
#  s/betatest/releasetest/
#  change to= to point to release builds on stage
./verify.sh -c moz18-firefox-$platform-major.cfg 2>&1 | tee $platform-releasetest.log

Linux passed OK, get timestamp and d/l location differences between betatest and releasetest logs. Had a bunch of trouble with slow mirrors (in particular mozilla.isohunt.com) for win32 and mac, so killed some wget processes (since we test twice per locale). This screws up diffing betatest and releasetest logs. Ran quick verify (./verify.sh -t instead of -c) for each platform to verify bouncer set up OK.

Enable beta snippets

Safe to do this without doing null snippets because there are no end-users of partner builds on beta channel (kev and metrics website confirmed last MU).

cd /opt/aus2/snippets/staging
time ~/bin/backupsnip 20090414-Firefox-2.0.0.20-3.0.9-MU-beta
real    39m15.394s

real    0m4.426s
user    0m0.013s
sys     0m0.369s

At this point we had to firedrill 3.0.10 for a top crasher

2.0.0.20 to 3.0.10

Generate Null Partner Snippets

Need to block those partners which currently don't have a MU configured.

Create snippets

Nothing to do here - we started off with a full set of nulls, then either overwrote with valid major update for partners, or revoked a partner major update by putting back in nulls.

Push live

Nothing to do

Verify nulls

We should still check though, using the list of URLs we generated last time.

Which is expected, those MU are live and therefore non-null info returned.

Repeat for each other two platforms, get no failures.

Enable release snippets
