[skiplist] - please add Touch
Bad Memory to prefix Signature Reg Ex
Please add TouchBadMemory to skiplist. Example crash report: bp-1a11b3bd-a0ff-4423-993f-674582120121 The relevant stack frame there is #3.
It's #2 top crasher in FennecAndroid 12.0a1 with a bunch of different stacks so it will help to breakdown.
Laura, can you take this?
Remove bug 727410 from dep change, it was resolved without this, but this is an important fix still.
No longer blocks: 727140
Please also add MOZ_Crash and MOZ_Assert (example: bp-1eb2b5ed-7e75-4c76-bf00-255842120309)
Fwiw, I think how we currently handle this list is ridiculous. We need to get this list checked in to hg.m.o so that developers can add words to it as we see fit.

This is a Socorro configuration and doesn't have a bit to do with hg (Socorro is on github). It's in the Socorro repo of course and you can always send a pull request for it if you like.
What I mean is, the skiplist should not be owned by the Socorro project. It should be owned by the users of https://crash-stats.mozilla.com/ ie. the developers of the products that reports its crashes there. It's we that have an interest in a good skiplist and we are the ones that knows what should be on it for it to be good. Having to wait around months for someone else to add a single word to a file and check it in is extremely frustrating. This doesn't work! Let's put this file in mozilla-central and managed by #developers, have a bot upload it and install it on crash-stats.mozilla.com on daily basis, or something... If you want it in github, fine, where do I apply for commit access? (I specifically do NOT want any Socorro people be the gatekeepers to changing the skiplist, they have proved they aren't good owners)
(In reply to Mats Palmgren [:mats] from comment #8) > What I mean is, the skiplist should not be owned by the Socorro project. I disagree. It only affects crash-stats.m.c so it should be somewhere closely connected to it, either in its site-specific configuration (where it is right now) or in the admin interface for it (bugs are filed for that, code contributions welcome). > Having to wait around months for someone else to add a single word > to a file and check it in is extremely frustrating. This doesn't work! It should never take months, I'm with you here. We have Socorro updates ship every week, things should always go into the next update. Sometimes the bugs are not written in an actionable way for the team, though. > Let's put this file in mozilla-central and managed by #developers No, that would make signatures change every day at random because someone would find out that something changes, and that would make tracking crashes over time completely useless (it's enough hassle to pull strings together when changing the skiplist now every week with Socorro releases). It also sometimes needs discussion of what list something should go on, etc. > If you want it in github, fine, where do I apply for commit access? You don't need direct commit access to the repo, if you send a pull request, people get notified and pull it in within a day, usually. > (I specifically do NOT want any Socorro people be the gatekeepers to > changing the skiplist, they have proved they aren't good owners) Now you are insulting Mozilla community members, that won't be tolerated.
fyi, mats, even if it was in hg; laura handles the requests pretty fast esp if you give her the regex correctly. I've had no issues with getting my requests within 24 hrs. The change however won't show until the next release of socorro if I'm not mistaken? The data doesn't get back processed, so you will still see a lingering of the old signature for a while.
Let's go to the heart of the matter, should this be in the prefixlist or in the ignorelist?
(In reply to Robert Kaiser (:email@example.com) from comment #11) > Let's go to the heart of the matter, should this be in the prefixlist or in > the ignorelist? libmozalloc symbols are in the prefix skip list, which is the default one.
blassey said on IRC that "TouchBadMemory() should be treated like abort()" and given that https://github.com/mozilla/socorro/blob/master/scripts/config/processorconfig.py.dist#L206 seems to be where abort() matches ans taking to account what comment #12 says, I guess we can be pretty sure that prefixlist is what we want here.
