920706 - In crashtest runs, the SpecialPowers addon isn't installed if you use a custom filename for your manifest

Status: NEW

(Testing :: Reftest, defect)

Description

[Daniel Holbert [:dholbert] (AFK Aug 23-25)]

I frequently do targeted crashtest runs by doing e.g.
  cp ./path/to/crashtest.list ./path/to/mine.list
  [edit ./path/to/mine.list to inlcude only a few tests]
  ./mach crashtest ./path/to/mine.list

However, this got me into trouble when testing martijn's patch in bug 917061 comment 27 -- SpecialPowers wasn't being defined, for some reason.

Turns out that happens because we only hook up SpecialPowers if you're using the right manifest name, as shown here:
> 88     # I would prefer to use "--install-extension reftest/specialpowers", but that requires tight coordination with
> 89     # release engineering and landing on multiple branches at once.
> 90     if special_powers and (manifest.endswith('crashtests.list') or manifest.endswith('jstests.list')):
> 91       addons.append(os.path.join(SCRIPT_DIRECTORY, 'specialpowers'))

I'm pretty sure this is the only place we have a hardcoded dependency on what your manifest name is.

It'd be great to remove that hardcoded dependency.
