This testcase appears blank (it should show a small-caps 'A') and triggers assertion failures:

###!!! ASSERTION: invalid array index: 'i < Length()', file ../../../dist/include/xpcom/nsTArray.h, line 317

###!!! ASSERTION: Hmm, something went wrong, aOffset should have been found: 'mGlyphRuns[start].mCharacterOffset <= aOffset', file /Users/jruderman/central/gfx/thebes/src/gfxFont.cpp, line 2174

I think this is a regression on mozilla-central from the last day or so.

I can confirm that, but on linux x86_64.

My last homemade working version was based on changeset : http://hg.mozilla.org/mozilla-central/rev/222b23e8e64b ; Wed Jan 07 23:48:28 2009 -0500 (at Wed Jan 07 23:48:28 2009 -0500)

I made another homemade build some 28 hours later, and small caps display was busted.

 http://hg.mozilla.org/mozilla-central/rev/4fc89aa2ffec ; Fri Jan 09 10:19:48 2009 -0800 (at Fri Jan 09 10:19:48 2009 -0800)

I will try to look at tinderbox builds from late wednesday to see which change is guilty.

KCD makes extensive use of small caps and is busted by this bug; screenshot attached.

We now need to call FinishSettingProperties on the temporary transformed textruns we create.

The reftest isn't great --- in the future we'll probably want to change our small-caps implementation to use Opentype small-caps features, which could break this test --- but we should probably do this for now to make sure what we have doesn't break.

Roc, was any other patch checked into 1.9.1? I'm wondering because this bug cannot be seen on 1.9.1 with builds on Windows and OS X.

The patch that caused the regression has not been checked in to 1.9.1 yet, but it needs to be.

	Comment 12 • 16 years ago

FWIW: This patch can't land on 1.9.1 until bug 430332 (the regression source) lands, and *that* bug can't land on 1.9.1 until bug 470272 is fixed, per reasoning in bug 430332 comment 56.

Just kidding -- that's no longer true, per bug 430332 comment 58.  I'll push fixes for both bug 430332 and this bug in a minute.
