657348 - Why are there so many 6.0a1 nightly builds?

Attachment: nightly symbol files from symbol server

While looking to fix bug 649884, I noticed that we seem to have an awful lot of 6.0a1 nightly builds. The attachment has a list of all the 6.0a1 Windows symbol files from the symbol server, as well as the output of some cut | sort | uniq -c that shows that we have >1 nightly build for basically every day.

Are we really generating more than one nightly almost every day? Or do we have a project branch that doesn't have a MOZ_SYMBOLS_EXTRA_BUILDID set, so the symbol files are indistinguishable from those produced from mozilla-central?

The downside to this is that the symbol cleanup script only keeps 30 nightly builds worth of symbols around, so if we have >1 nightly per day, it winds up keeping a lot less than 30 days' worth.

Actually, it strikes me, maybe those are Win64 builds?

There also seem to be lots of linux64-tracemonkey builds, at least two nightlies every day:
firefox-6.0a1-Linux-20110416033343-linux64-tracemonkey-symbols.txt
firefox-6.0a1-Linux-20110416040208-linux64-tracemonkey-symbols.txt

      2 20110416
      2 20110417
      2 20110418
      2 20110419
(etc)

If it was, what would I need to set MOZ_SYMBOLS_EXTRA_BUILDID to?

It doesn't really matter, it's an arbitrary string. "win64" would be fine. That doesn't explain comment 2, though.

Is this a side effect of bug 592244 ?

I think it might be one of the project branches like tracemonkey but I have not had time to look into this and I doubt I will tackled before my EOD.

From looking yesterday at how new project branches get added they already set MOZ_SYMBOLS_EXTRA_BUILDID to the branch name.

Putting back into the pool.

Attachment: make sure to use deepcopy

turns out that all the generic projects were sharing tracemonkey's environments, which included MOZ_SYMBOLS_EXTRA_BUILDID. the extra builds are from other projects like devtools that were uploading their symbols with -tracemonkey appended.
