bug ??? - nulls/refreshes for partners (not needed)
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

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");'

- 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).

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.
