This is great work, and I'd like to see this integrated into something like the dev-tree-mgmt-type notifications where if there's evidence of a new crash or spike associated with particular check-ins we're notified. I know it's hard, and there may be false positives. Still, it might help us keep our crashes in check.

Who wants to volunteer to help make that happen? :)

Excellent job, David!

Cheers,

Damon

This might also be integrated in the crash-stats site, which is already
aggregating lots of information about crashes.

Just for the record, I've already found one crash bug looking through
David's lists, and have posted a patch for it :-)

https://bugzilla.mozilla.org/show_bug.cgi?id=549691

Looking per-nightly catches *all* crashes (not just topcrashes), and
can be valuable for that reason.

Nice! Chowse is sketching up how this will look in Crash Reporter,
and I'll work on coding it in for the next Crash Reporter release.

Where can I grab the Build IDs that we're using to populate dbaron's
page? Are we just fetching those out of the txt files on the FTP
site, or is there a better place to grab those?

Thanks,
Ryan Snyder

I just landed bug 474610 on 1.9.2 and 1.9.1 this morning. Also, I have a
Python script that does basically the same thing (but stores the results in
a sqlite db) here:

I'm just grabbing the text files from FTP (and then caching them).

I put the script I used to generate the page at
http://hg.mozilla.org/users/dbaron_mozilla.com/nightly-topcrash-generator/

I'd note that we currently (as of when I checked a few days ago)
only seem to publish the .txt files for mozilla-central and not for
release branches.

Hey all,

The links for the crashes for nightly builds are now available in
Crash Stats at:
http://crash-stats.mozilla.com/products/Firefox/builds

Let me know if you have any feedback for this page... Thanks David
and Ted for the pointers for the build info files!

Cheers,
Ryan
