Open Bug 972099 Opened 7 years ago Updated 3 years ago
A preference gfx
.color _management .force _srgb needs to move from .js to .py
Even though it isn't a default, we want to run the tests with gfx.color_management.force_srgb set to true. Right now, this is accomplished by setting this after the startup. However, changing that preference after the startup is not safe in general, so we are going to make it "read only on startup" type of pref (see bug 971126). In order to continue testing with gfx.color_management.force_srgb set to true, even though the default is false, my understanding is that we need to make a change to runreftest.py or some such.
Andrew, does the above description make sense, and is runreftest.py the right place for this change? If not, can you suggest the right approach, or point us to somebody else? Thanks.
I'd have hoped that the pref setting in reftest-cmdline.js happens before the pref gets read in the first place. Are you sure this is needed?

You can add the pref here, where it will be set as a user_pref in the profile: http://mxr.mozilla.org/mozilla-central/source/layout/tools/reftest/runreftestb2g.py#412 (In reply to David Baron [:dbaron] (needinfo? me) (UTC-8) from comment #2) > I'd have hoped that the pref setting in reftest-cmdline.js happens before > the pref gets read in the first place. Are you sure this is needed? We can't use reftest-cmdline in b2g because we are starting the emulator binary instead of a gecko binary. The emulator is what starts the gecko process and we don't have control over the command line we can pass it. So instead we kill the b2g process after it has been started, swap in a new profile and restart it manually. There's a bug somewhere to abstract the prefs out of reftest-cmdline and share them with b2g/android, but as of now they are just copied :(

Are you sure this is needed? Sadly, it seems to be. If I register this pref with a callback for a "modified value", the callback happens and the value is modified.
OS: Mac OS X → Windows 7
Note that, in this particular case, the issue is only relevant on Windows.
Andrew, I can't tell from the conversation if this is what you're suggesting needs to be done.

Oh sorry, I didn't realize this was Windows only. I agree with :dbaron then, I'm confused as to why the pref in reftest-cmdline.js isn't being set at startup. In this case I don't think you want to touch any of the b2g/android files (i.e runtestsb2g, b2g_start_script, and bootstrap). Did you mean to do that (I assume I just confused you with comment 3)?
Right - I made the change in there because that preference was being set on b2g - even though it is basically ignored there. So, for consistency. I definitely don't know this code well enough to understand why it isn't being set at startup. I can investigate, but that'll take a while. Does it make sense to just make the change to runreftest.py (as above) and land that now to unblock another bug and open a bug to figure out why this is happening?
