This adds support for class="reftest-opaque-layer" and for
reftest-assigned-layer="some-layer-name" to the reftest harness.
From reftest/README.txt:
Opaque Layer Tests: class="reftest-opaque-layer"
================================================
If an element should be assigned to a PaintedLayer that's opaque, set the class
"reftest-opaque-layer" on it. This checks whether the layer is opaque during
the last paint of the test, and it works whether your test is an invalidation
test or not. In order to pass the test, the element has to have a primary
frame, and that frame's display items must all be assigned to a single painted
layer and no other layers, so it can't be used on elements that create stacking
contexts (active or inactive).
Layerization Tests: reftest-assigned-layer="layer-name"
=======================================================
If two elements should be assigned to the same PaintedLayer, choose any string
value as the layer name and set the attribute reftest-assigned-layer="yourname"
on both elements. Reftest will check whether all elements with the same
reftest-assigned-layer value share the same layer. It will also test whether
elements with different reftest-assigned-layer values are assigned to different
layers.
The same restrictions as with class="reftest-opaque-layer" apply: All elements
must have a primary frame, and that frame's display items must all be assigned
to the same PaintedLayer and no other layers. If these requirements are not
met, the test will fail.
This attribute used to force APZ to be used on content processes even if the
overall APZ pref was false. However, this has a couple of problems, which cancel
each other out:
- If the pref is false, the APZ machinery is never created, and so it's
impossible to have content processes "using" APZ.
- The reftest harness checks for the pref and ignores mozasyncpanzoom when
evaluating the "asyncPanZoom" condition in reftest manifests.
Therefore, any reftests which were skip-if(!asyncPanZoom) would never run unless
the pref was set, and in those cases the mozasyncpanzoom attribute would not be
needed at all, as APZ is already enabled with the pref.
However, the mozasyncpanzoom attribute would cause some parts of the child
process code to behave as though APZ was enabled, which is incorrect. Removing
this attribute and relying solely on the pref corrects that.
Using undefined has the advantage that we can use < and > tests with the
OSX variable. (We currently have no such tests in the tree, perhaps
partly because they didn't work with non-OSX being 0.)
In some cases the area reported by MozAfterPaint can be extremely large. Since
that area determines what we pass to drawWindow, we could end up trying to
drawWindow an area that is too large for drawWindow to handle. Instead, this
patch clamps that area to the canvas size so that we don't unnecessarily try to
paint (and fail at painting) the whole invalid area.
When running reftests on Mulet, we do not want that forced update
checking gets triggered. We can block this by setting the following
prefs:
- app.update.enabled to false
- app.update.url.override and app.update.url to empty string
We also disable tiles-related pinging and downloading by setting empy
values for:
- browser.newtabpage.directory.source
- browser.newtabpage.directory.ping
Gaia also does force check app updates at some point, so we introduce a
new pref, webapps.update.enabled, that we can use to make sure webapps
update won't be triggered.
The logcat format used by tbpl jobs in some (maybe all) cases now has a
timestamp and other decorations at the beginning of the line. The regex that
was previously added to filter out reftest failure lines duplicated in logcat
no longer matches the lines correctly; this makes the regex more generic so that
the filtering works again.
Fixes:
./mach reftest error: runreftest.py: error: could not find the application path, --appname must be specified

This issue manifests itself as the reftest extension not being installed
for local testers. This is because the extension's location is
determined relative to SCRIPT_DIRECTORY, and for local testers, __file__
ignores the symlink from $OBJDIR/_tests/reftest/runreftest.py ->
$SRCDIR/layout/tools/reftest/runreftest.py.
This was changed in Bug 915865.
Instead of grabbing attributes off options at every call site, pass
in the options object to processLeakLog, and attempt to get the attributes
there. If not present, use a restrictive default value.
This will prevent silent harness failures if one of the many ways to invoke
processLeakLog fails to set up these options, and makes it so they
don't have to set it up if they don't care.
