Why can't mozcrash automatically pick the temp folder > in case no symbols_url is present? It could! The code in mozcrash predates the existence of these minidump_stackwalk binaries that have the symbol server URL baked in, so this wasn't a use case we envisioned. We've already got code that creates a temp dir to extract symbols when you pass in a URL to a symbols.zip, so we could just let you pass in None and create an empty directory to use: https://dxr.mozilla.org/mozilla-central/rev/5b2baa5e9356644a7ed0b73e422eaff62e159ffb/testing/mozbase/mozcrash/mozcrash/mozcrash.py#176
Given that this blocks crash analysis for l10n builds of Firefox UI Tests I'm going to take this bug.

Here an example of the current behavior of mozcrash with a de locale build. No symbols_url nor symbols_path has been specified: https://treeherder.mozilla.org/logviewer.html#?job_id=2020778&repo=mozilla-aurora#L879 06:24:15 INFO - PROCESS-CRASH | runner.py | application crashed [None] 06:24:15 INFO - Crash dump filename: c:\jenkins\workspace\mozilla-aurora_functional\build\tmpuutlym.mozrunner-1456496626\minidumps\99370cd3-32fd-4f20-9a05-56c79636b98e.dmp 06:24:15 INFO - No symbols path given, can't process dump.

https://reviewboard.mozilla.org/r/37941/#review34555 > You need to set `self.remove_symbols = True` like the url case below. Oh, right. I will add this line below line 169 so we do not fail in case `mkdtemp()` fails.
Lets keep the bug open after landing on mozilla-central so that I can release the version to pypi.
Keywords: leave-open
Version 0.17 has been uploaded to pypi. Ted, given that our firefox-ui-tests make use of the in-tree version of mozcrash I would like to get this patch backported to at least 46.0 and even better 45.0esr. I don't think that we can land anything on the 45.0 release branch. What do you think?

It's a pretty inoffensive patch, should be fine to branch-land. Are you intending to backport the firefox-ui-tests in-tree to those branches, or what?
Flags: needinfo?(ted)
Our tests are already existent in-tree down to the current release branch (45.o) and mozilla-esr45. Due to crashes we have a lot of test jobs for which mozcrash doesn't work because of locale builds. So we could 1) backport this patch (i assume without the version bump) or 2) we set a fake folder for symbols-url. Both would work for me. Maybe the latter is better?
Flags: needinfo?(ted)
Either way is fine with me. This patch is pretty inoffensive, and presumably you're satisfied with how it works, so backporting it is probably less work than writing a new patch just for the branches.
Flags: needinfo?(ted)
So this patch works great with localized Aurora builds without specifying any symbols path: https://treeherder.mozilla.org/#/jobs?repo=mozilla-aurora&filter-searchStr=Firefox%20UI&filter-tier=2&filter-tier=3&selectedJob=2097106 > PROCESS-CRASH | runner.py | application crashed [@ RtlAllocateMemoryZone + 0x2a6281] Sheriffs please backport only attachment 8726383 [details] to mozilla-beta, which is a test/tools only change. Thanks.
