Comment 1

[Scoobidiver (away)]

It is #1 top browser crasher in Fennec 6.0.

Comment 2

[Josh Matthews [:jdm]]

This looks like we have a null mSurface in gfxASurface.

If CheckSurfaceSize fails, we are stuck with a NULL mSurface pointer (and mSurfaceValid is false, but we don't appear to check that religiously).

Ensure that gfx surfaces contain a valid mSurface pointer even if the requested dimensions are disallowed.

Nevermind, I noticed that this check is repeated in a bunch of places. I'll address all of those as well.

Comment 6

[Brad Lassey [:blassey] (use needinfo?)]

Joe, we're going to want this in Beta(6) and Aurora(7). I'm assuming we're not going to want the refactor patch for the release branches. If my assumption is correct, can we get the jdm's smaller fix reviewed and ready for release branch landing.

Comment 7

[Joe Drew (not getting mail)]

Is it the case that attachment 547199 [details] [diff] [review] will fix this bug? It's not clear from reading comment 5.

Comment 8

[Josh Matthews [:jdm]]

A variation of the existing obsolete patch should solve this bug, since it will ensure that all gfxImageSurfaces will contain valid cairo surfaces. I can do a belt-and-suspenders fix as well by adding a check for CairoStatus in the android nsWindow code.

Comment 9

[Josh Matthews [:jdm]]

A regression window here would be interesting, at the very least, to figure out why this topcrash started occurring.

That is a lie

Comment 13

[Josh Matthews [:jdm]]

My idea of creating a null cairo surface is too invasive and potentially-behaviour-changing for me to feel comfortable about it. Here's a much more reliable belt-and-suspenders solution that prevents calling cairo functions on null surfaces (some functions had the check, others didn't, so I figured me might as well go all out), as well as checking the CairoStatus of the new surfaces in the Android window impl and avoiding using them if they're not valid.

[Chris Jones [:cjones] inactive; ni?/f?/r? if you need me]

I accidentally perma-reproduced this by putting Nightly into "zoom mode", where it's zoomed to fill the screen on a Xoom.  FWIW.

This seems like the wrong approach. If we want to be able to call functions on invalid surfaces we should just initialize the surface and let cairo do the checking. cairo already has the concept of a null surface.

Comment 17

[Josh Matthews [:jdm]]

I was seeing test failures when I tried that. For the patch to address the topcrash on Beta, I really want to go with the simples and most reliable option here.

Joe, you're on the hook for gfx/ changes, Doug's in charge of the Android window ones. Try was all green.

Prevent calling cairo functions on invalid surfaces through gfxASurface.

On the android bits:
  |if (targetSurface && !targetSurface->CairoStatus())| is what we do on windows.

No idea if the gfxASurface changes are good.  I think you can have a null surface in cairo so, those cairo functions should do the right thing.  Maybe joe or jeff know the details.

nsWindow parts are obviously good and correct. gfxASurface I want Jeff's input.

oh, and we do have a ASUS TF101 EEpad Transformer (with keyboard) to hammer on.  Since most of the crashes are being reported on that platform

Comment 28

[Scoobidiver (away)]

According to crash stats, there have been no crashes in Fennec 6.0b4 while there were about 15 crashes per day in previous Beta builds.
See https://crash-stats.mozilla.com/report/list?range_value=4&range_unit=weeks&signature=_moz_cairo_surface_get_device_offset&version=Fennec%3A6.0 and click the Graph tab.
