Status: RESOLVED FIXED

(Release Engineering :: General, defect, P2)

Description

[Daniel Holbert [:dholbert]]

Looks like MozillaTry TBPL has been perma-purple since a little after 1pm today. (roughly)

(at least on Linux - those are the only builds to have completed in pushes since 1pm today)

Latest failure:
http://tinderbox.mozilla.org/showlog.cgi?log=MozillaTry/1297118227.1297119586.1923.gz

Seems likely this is a regression from bug 579131, with the graph server not expecting to get ctor results for Try.

Purple is just Linux32 and Linux64 builds, both opt and debug.

We're attempting to post the ctor results to the 'MozillaTry' branch, when the rest of Try uses 'TryServer'. Aki figured out that's because we've got a hardwire to the tinderbox tree name here
 http://hg.mozilla.org/build/buildbotcustom/file/default/misc.py#l989
when creating the builder.

Aki is going to back out the part of bug 579131 that got deployed today. The graph server failure occurs before we package tests and symbols and trigger talos and unit tests, so those never happen.

Backed out, reconfiged Try.
Should be fixed for any Try build that happens after this point.
