To support downloadable fonts, a user font set object is created when @font-face rules are found in style content (see bug 441473). For each @font-face rule that is processed, a font entry is added to the user font set object. However, when a stylesheet is disabled, the @font-face rules for the disabled stylesheet need to also be disabled. Discussing this with dbaron, we decided that it made sense to simply rebuild the user font set object when stylesheets containing @font-face rules are enabled or disabled (see bug 441473 comment 77).
Flags: blocking1.9.1?
Updating summary to reflect that we also need to do this when rules in sheets are modified, added, or removed. (That requires hooking into a different code path than enabling/disabling entire sheets, so it's worth noting.)

Priority: P1 → P3
So hooking in to nsCSSRuleProcessor::ClearRuleCascades or perhaps just nsCSSStyleSheet::ClearRuleCascades will catch the enabled/disabled cases and the rule insertion/removal cases -- that's probably the best place to clear the old user font set. You also need to hook into nsCSSRuleProcessor::RefreshRuleCascade to catch media-dependent style sheets.
Taking per email discussion with jdaggett.

Attached patch work in progress (obsolete) — Splinter Review
Here's some work in progress; the marking-dirty stuff actually looks harder than I thought it would be; I think I might need to ensure that all of these things happen inside BeginUpdate/EndUpdate (UPDATE_STYLE) and then query all the rule processors for dirtyness inside the style set's EndUpdate.

How about a version that compiles and runs, at least?
Attachment #346342 - Attachment is obsolete: true
I'm going to attach the current state of my thinking. I have a set of four patches that I think ought to work (who knows, maybe they're close), but I haven't done any testing. (For now, I'll need to switch to a different platform to do that testing.) This is roughly the same as attachment 346347 [details] [diff] [review]. It builds the array of @font-face rules up from the levels of the cascade, since some of the time we can reprocess one level of the cascade but not others (due to various types of dynamic changes). Since yesterday, I fixed things so we again don't have a user font set when there are no @font-face rules. This moves InsertFontFaceRule from one file to another, which makes the patch look big. (I took out two unused variables while I was moving it.)
Attachment #346347 - Attachment is obsolete: true
I finally came up with a simple way to do this, by observing that everything that goes through one of the two codepaths in comment 2 also goes through one of these two codepaths. The patch in comment 1 means we don't actually need any clearing at the points I mentioned in comment 2 as long as we do the rebuilding, since the patch in comment 1 means we're storing the data in the RuleCascadeData, which is already cleared or swapped out in those codepaths. I need to verify my assertion that this should work more closely and probably add a bunch of comments pointing out that this is how things work.
This optimizes the rebuild with an array comparison. I think the main thing this saves is really not rebuilding the font set, but the ensuing style change reflow (see patch 4).
Patch 2 introduces the possibility of removing @font-face rules from the set of rules we're considering. This patch causes us to do a style change reflow in that case just like we do when font loads complete, and adds comments both similar cases pointing at the other.
In comment 7, when I wrote "the patch in comment 1", I meant "patch 1".
I've made a bit of progress on tests, although I still need to do a lot more. I'd like to test interaction of the dynamic cases with the ordering of rules since I think the changes I've made should have improved that, except that the static tests I've written for that don't work on the trunk. I also need to test media changes as well. I also need to figure out how to actually meet the security restrictions; right now running them from file: URLs hits the can't-cross-directory security restriction, I think. I also need to make sure that the tests that should be failing on the trunk are, and that the ones that should be passing with my patch are, etc.

This uses relative URL resolution so that one of the URLs can be served over HTTP and the other can be about:blank or a data: URL.

This allows "HTTP(..)", "HTTP(../..)", "HTTP(../../../)" for reftests so that we can relax the restriction that all the resources need to be in the same directory. This lets us use downloadable fonts in reftests from a resource directory containing fonts. (We can't use file: because of the cross-directory security restrictions on file:.)

Comment on attachment 346741 [details] [diff] [review] patch 6: allow variants of HTTP so that resources can be served from parent directory I wish reftest weren't line-based but rather whole-manifest-based, so we could just have one server rooted in one location and we wouldn't have this weird directory restriction. Probably too much effort to make the change worthwhile, alas...

I had to merge 2, 3, and 4. I don't think it's much of a loss. I'm now forcing a reflow when the user font set changes (not just non-null to null), since otherwise we'll never hit the loader bits.

This prevents the font cache from returning a font metrics object that has the wrong user font set. I had to add to nsIFontMetrics (though I could have added to nsIThebesFontMetrics, but I don't see why it matters and this is a little less ugly) because the font cache is in gkgfx, which doesn't link against thebes, so I can't call methods on a font group.

Comment on attachment 346929 [details] [diff] [review] patch 2-3-4: do the necessary rebuilding when needed Shouldn't GetUserFontSet still do a (lazy) rebuild?
(In reply to comment #26) > Shouldn't GetUserFontSet still do a (lazy) rebuild? I suppose it could (that was my original approach), but any case where it matters, we're not even going to call GetUserFontSet unless we force a style change reflow. So if we're not forcing that style change reflow, gfx will never decide that it wants to load the fonts (and thus force another style change reflow) and layout will never rebuild text runs to get to a situation where it has different font groups. So I'm not sure I see the point given the rest of the changes.

Why the need to call UpdateFontList? This will happen automatically whenever a text run is recreated, the point at which font matching is performed. Also, isn't there a chance that after a user font set has been torn down and recreated that you could end up with an identical pointer?

(In reply to comment #33) > I'm not sure I quite understand this. Why the need to call UpdateFontList? > This will happen automatically whenever a text run is recreated, the point at > which font matching is performed. Failing to call UpdateFontList was resulting in incorrect metrics being returned in the function GetNormalLineHeight in nsHTMLReflowState.cpp. This function calls aFontMetrics->GetExternalLeading(), which in turn uses the metrics on the first font in the font group. If we don't call UpdateFontList, the first font in the font group isn't updated until later, and we fail a bunch of the reftests because the line spacing is incorrect (since the test ends up still using the line spacing for the fallback font, while the reference uses the line spacing from the downloaded font). http://hg.mozilla.org/mozilla-central/annotate/d11e76e6fab9/layout/generic/nsHTMLReflowState.cpp#l1992 > Also, isn't there a chance that after a user font set has been torn down and > recreated that you could end up with an identical pointer? No. Since gfxFontGroup::mUserFontSet owns a reference to mUserFontSet, the old one won't actually be destroyed until after all the font groups pointing to it have gone away.

Is this going to be the only situation where we hit this? I fear that if we have one fontgroup user needing to do this (from a distance), there may be others. Or should the gfxFontGroup::GetFontAt(PRInt32) implementations do the UpdateFontList?

Yeah, I was wondering at some point if this should be elsewhere. I'm curious what John thinks.
Comment on attachment 346929 [details] [diff] [review] patch 2-3-4: do the necessary rebuilding when needed So for some reason this patch seems to make layout/reftests/css-import/290018-1-ref.html fail because the quirks style sheet starts applying to the reference (but not the test). (I need to double-check that I've diagnosed things correctly...)
The problem seems to be the AppendFontFaceRules call in nsPresContext::FlushUserFontSet, which I guess causes us to build the rule cascade earlier. I suppose I should just finish bug 450191, though I should probably look into this a little more; perhaps there's something I could be testing to avoid an early call. (I thought that reftest failure was just a random failure like a bunch of others, but today I bisected all the patches in my tree to figure out what was causing it.)
Here's a revised version of patch 2-3-4 that goes back to lazily rebuilding in the initial case and thus fixes the problem in comment 39 and comment 40. I'll attach an interdiff for review shortly, since the previous patch was already reviewed.

My inclination is to stick an assertion and comment in the GetFontAt implementations so we don't pay the performance penalty of checking every time in release builds, but if somebody else runs into the same problem they'll hit the assertion and quickly know what the problem is (and see the comment suggesting the possible alternative).

Attached patch patch 2-3-4 interdiff #2 (obsolete) — Splinter Review
Here's a second interdiff for patch 2-3-4. It turns out that my revisions yesterday caused a bug where StyleChangedReflow would get called during the lazy build that we do during the first GetUserFontSet call. Since that code was getting confusing (it got me, clearly), I switched from two booleans to three that better describe what I care about, and as a bonus got to deal with out-of-memory while posting events a little bit better. At this point I'm not sure if it's easier to re-review the whole patch; I'm not sure of a good way to combine the interdiffs, which overlap a lot. If I could combine them, the interdiffs would probably be easier...

And this fixes the obvious mistake in my second interdiff, which, amazingly, wasn't caught by my tests. I should go add something that will catch it to my tests. (I guess none of them require rebuilding twice, at least not in a way that won't do anything at all unless we force the reflow!)

That sounds sensible in principle. I don't know, however, whether that assertion is strictly required. I wonder whether GetFontAt may be called at a time after another reflow has already been scheduled (but not started)? If so, it's not strictly necessary to get exactly the right font (though getting the right font would still be nice). (I don't mean this must hold up this patch. I'm asking the question because I don't yet know the answers.)

Could we push that part off to a separate bug?

virtual gfxFont *GetFontAt(PRInt32 i) { + // If it turns out to be hard for all clients that cache font + // groups to call UpdateFontList at appropriate times, we could + // instead consider just calling UpdateFontList from someplace + // more central (such as here). + NS_ASSERTION(!mUserFontSet || mCurrGeneration == GetGeneration(), + "Whoever was caching this font group should have " + "called UpdateFontList on it"); + I don't think this code will ever execute, since each of the per-platform font group classes override this method: http://mxr.mozilla.org/mozilla-central/source/gfx/thebes/src/gfxWindowsFonts.cpp#889 http://mxr.mozilla.org/mozilla-central/source/gfx/thebes/public/gfxAtsuiFonts.h#135 http://mxr.mozilla.org/mozilla-central/source/gfx/thebes/src/gfxPangoFonts.cpp#1402 So I think you need to dupe the assertion into each of those methods.

Good point. This copies the assertion to all GetFontAt implementations. I reran the font-face reftests (including patch 9c) with this patch, and still didn't hit the assertion, which is good (on Linux, Windows, and Mac).
