Bug 30223 – [LayoutTests][Gtk] Set a common Gtk theme as default and update the results

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Zan Dobersek]

At the moment, unexpected failures can occur because of running the tests while having different Gtk themes set as default. This appears on the Gtk buildbots, where tests are run under Xvfb, in which Raleigh is used as the default theme. Running the tests with a different theme can produce failures.

The Raleigh theme is also Gtk's default and is as such present on every Gtk system. Therefor, I recommend setting this theme as default in the DumpRenderTree.

This bug should be considered for closing when a default theme is set and the results are updated to reflect the changes.

Sounds fine to me.  Seems silly to wrap this line when lines just below it have no wrapping.  WebKit style has no official column width.

Also WebKit style is to use 0 instead of NULL for c++ code, although maybe the gtk code follows some other style?  check-webkit-style should help identify some style issues.

looks fine, but cq- for the style oddities.

Maybe consider setting the font names and sizes as well?  But maybe that's a different bug.  If you're really loading all of this from GtkSettings you'll want to override all of 'em, including cursor-blink etc.

(Is this committable without test rebaselines?  Or are they all baselined to Raleigh?)

I'll raise a discussion on the irc channel about 0 vs NULL problem. I'll also see about opening a bug for style cleanup of Gtk port's code.

Font families and sizes are taken care of in resetDefaultsToConsistentValues function, which is called before each test. I don't think overriding any other setting would do any good, or harm.

If it, however, appears that it should be done, the code should be updated - moving all of the overrides of GtkSettings into a new function for a better overview.

Rebaselining patch will be attached to this bug asap.

Replaces use of wrapped lines.

Using NULL as sentinel is what we seem to do now and I see little reason to change that. Could you please watch the bot when landing it?

Updated results

This updates results for two tests that were failing on the buildbots because results were generated in a theme different than Raleigh.

Removing cq? on this closed bug.  I assume this patch was already landed.
