talos needs to support new upload dir structure


(Release Engineering :: General, defect, P3)



(Not tracked)



(Reporter: rhelmer, Unassigned)



Currently, Talos hits two bugs that the old test infrastructure also has:

1) there is a race condition between the start time on tinderbox and the actual depend build available, so sometimes the start time is reported incorrectly
2) clobbers are not tested, but results are reported as if they were

The core problem is that each depend build is uploaded to a dir like:

Each clobber build is sent to:

Cause of #1: Buildbot asks Tinderbox for the latest depend build, and queues the result. Since the former build.exe is overwritten each time, it's very likely that a new build has been uploaded in the meantime, so the start time is not correct

Cause of #2: Talos only knows to check the former style of URL, not the latter.

What I'd like to do to fix this is to land bug 291167, as soon as possible after we've switched to Talos from the old bl-bld* machines. This means that the depend builds will be uploaded to a URL like:


To fix #1 Talos will need to use the start time derived from the TinderboxPoller Change in order to find the correct build to download.

To fix #2 Talos will need to detect if binaryURL is set in the Change from TinderboxPoller, and follow that URL to download the correct clobber build. TinderboxPoller does not currently honor this field, it will need to be made to do this.

I think that it would be better to have #1 fixed and Talos skipping clobber builds, than the current situation (getting the start time wrong and falsely reporting that it tests clobber builds), so fixing #1 seems like the more critical bug here.

from bug 291167's attachment (303341):

   # Note that we traverse this code for "hourlies" as well as nightlies/clobbers
+  # $package_name, and hence $short_ud,  would be (eg) 
+  # "fx-linux-tbox-trunk/1202546936" if DependToDated is set, 
+  # "fx-linux-tbox-trunk/" othersise, and "2008-02-09-00-trunk" for clobbers.

so, I'm reading this as unixtime on the hourly builds and full time for clobbers. We should also add some logic to detect clobber builds in quickparse.txt and extract the "binaryUrl" included there.

still working on moz2 stuff which, is taking longer than expected. Will pick up again if time permits.

From the work in bug 291167 talos now handles downloading from dated directories.  Bug 433639 has been filed to have talos correctly handle nightly builds.  From my reading of the bug there is also a question of how to handle clobber builds - is this still an issue?  If so, can we rewrite this bug to only handle the missing case and not the problems that are being fixed elsewhere?
From talks with nthomas talos should handle clobber builds the same as nightlies - so issues with testing clobbers will be covered with bug 433639.

Otherwise this bug is fixed.
