Status: RESOLVED DUPLICATE of bug 980032

(Firefox :: Toolbars and Customization, defect)

Description

I found this regression:
https://groups.google.com/forum/#!topic/mozilla.dev.tree-management/cTpU15SA-Zs

here is the graph:
http://graphs.mozilla.org/graph.html#tests=[[309,64,24]]&sel=none&displayrange=7&datatype=running

it is a single changeset:
http://hg.mozilla.org/integration/fx-team/pushloghtml?fromchange=3eb813b8fed8&tochange=092b3b1a185c

this appears to be caused by bug 964257 and only seems to be affecting osx 10.8.

Hm - Datazilla disagrees about the source of this regression:

https://datazilla.mozilla.org/?start=1393445873&stop=1394050673&product=Firefox&repository=Fx-Team&os=mac&os_version=OS%20X%2010.8&test=cart&graph_search=092b3b1a185c&project=talos

092b3b1a185c is highlighted in that link, and is clearly not introducing any regression. There are a few before it though.

Who do we trust here, jmaher?

ok, here is see 2 different revisions of interest:
1) https://hg.mozilla.org/integration/fx-team/rev/a781d8486ebc
* 1-customize-enter.all.TART
* 2-customize-exit.half.TART

2) https://hg.mozilla.org/integration/fx-team/rev/d67d16611935
* 3-customize-enter-css.half.TART

I suspect the graph server stuff is getting fuzzy because it doesn't work well with a summarized view.

both of these revisions are not the original one and luckily not merges from another branch.

Pretty sure this is a dupe of bug 980032. We'll continue over there, since that's where more information is.
