685667 - Disable running 64-bit Windows talos and unit tests on all branches except mozilla-central until we have enough capacity

Status: RESOLVED FIXED

(Release Engineering :: General, defect, P2)

Attachment: disable win7 64-bit tests for all branches except for mozilla-central

We have right now hundreds of pending WINNT 6.1 x64 test jobs because we only have 5 testing slaves.

Until we have more we should disable them for all branches except for mozilla-central.

Blocking on bug 667024 until we have enough capacity to re-enable them.

I will attach a second patch to show which builders are being removed.

Attachment: differences between previous list of builders per master

This was generated by running the following command:
hg up -C && hg pull -u && rm -rf master_dir && ~/repos/releng/braindump/buildbot-related/dump_masters.sh > old && cd ~/repos/buildbot-configs/ && patch -p1 < /Users/armenzg/moz/patches/disable_win764_tests_on_branches.diff && ~/repos/releng/braindump/buildbot-related/dump_masters.sh > new && diff -pU 8 old new > differences

I have a modified version of dump_masters.py which only lists the builder names.

r+ if you fix the iteration piece (or explain why it's necessary).

Any ETA on how long until we get capacity? Can you poke relops about it in the relevant bugs?

Why iterate for only one branch?

I wanted to iterate if we wanted to add more branches but for now let's keep it simple.

Landed & deployed with:

Let's reopen once the dependent bug gets closed and we have enough capacity.

Attachment: missed to disable win64 for NO_MAC list of suites

It seems to affect chrome.

Probably related to bug 686238.

Won't this remove the chrome builder for mozilla-central ?

Attachment: missed to disable win64 for NO_MAC list of suites (v1)

You are right.
This patch does the job as I have loaded up bm15-tests1-windows and we only have coverage for mozilla-central (which is what was intended).
