More testing over past 3 days, narrowed down where it quit working,
the following link shows all the patches (over 100) that landed
between when it was last good, and went broken:
http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=fcc533f691e9&tochange=a21fd4d085ad
Last build it worked is: 20120831030612 fcc533f691e9 where first 1/2
is date 2nd half if changeset
First build it failed is 20120901030528 a21fd4d085ad
Archives for hourly tinderbox builds don't go back far enough to
regression search beyond the above Nightly builds. Perhaps a visual
inspection of the patches in the regression range will reveal which
patch has broken the Radar Loop from updating. Nothing jumps out at
me, but I'm not a coder. There were some Array patches. Observing
the forecastfox.sqlite file in the profile I can see it update at 15
min intervals, even in broken builds that does not update the Radar
Loop, and examination of the sqlite file with SQlite-browser the Epoch
date is also correct, so its just something blocking the painting/
updating of the Radar Loop. I've been trying to read through the
forecastfox.jar file, but its huge and so far I've not found point in
code (keeping in mind I don't really know what I'm looking for) that
would trigger the update download and updating of the .gif for the
Radar.
I hope this helps some to find the area that needs fixing, or perhaps
a bug will need to be filed on Firefox for the breakage.
