Closing bug. 799391 4 danakj 2013-01-03 08:47:44 -0800 Looks like this change is causing crashes: http://code.google.com/p/chromium/issues/detail?id=168173 Sorry, but it looks like it needs to be reverted. I've also confirmed locally that reverting this fixes the crashes. 799394 5 webkit.review.bot 2013-01-03 08:49:49 -0800 Re-opened since this is blocked by bug 106019 799411 6 benjamin 2013-01-03 09:36:35 -0800 Did you just revert based on a downstream issue? (this has been discussed recently on the mailing list) Can you give me more information about the problem. As far as I know, no WebKit test failed with the patch. How did you rule out your compiler or project settings? I am honestly more than a little annoyed this was reverted without any information for me to work on. 799417 7 danakj 2013-01-03 09:44:54 -0800 We ran the test in gdb for quite some time but were unable to get any much information about what was causing the crash. As you can see in the backtrace on the linked bug, the crash in gdb is happening at the entrance to the method. The pointers going into the method are all fine, of course, and gdb didn't have anything interesting to say about the two matrices, they look valid. I can provide the contents of them for you though, if you feel that will help. This seems to point to a problem in the implementation of the method, which is surely going to cause a problem for all ports. These tests just happen to cause it to trigger reliably. This has really nothing to do with "downstream vs upstream" as far as I can tell. I don't know what project settings you're referring to that would change whether multiply() should crash or not given two matrices. I'm sorry we don't have better test coverage on the webkit bots for functions like this, but I don't think it's that unusual for chromium bots to uncover bugs or problems that the webkit bots do not for that reason. We're looking into running the chromium compositor unit tests on the EWS bot, or on the canary waterfall, which would have helped here.

There are many ways to screw that up despite completely correct code. Please give me the disassembly at the point of crash and the content of registers.

you go, %rsi is unaligned. It is the this pointer here. If it was allocated on the stack, you may have either a bug in your compiler, or someone mess-up the alignment of the stack (likely at library boundaries).

In the patch, the alignment is specified on 16 bytes on the stack: typedef double Matrix4[4][4] __attribute__((aligned (16))); This is not followed in Chromium for some reason. Maybe? 1) Compiler bug (the assembly you pasted looks like quite aggressive debug code - do you have the bug in release?). 2) One of your libraries specify a different stack alignment? 799495 14 jamesr 2013-01-03 11:05:51 -0800 (In reply to comment #13) > 2) One of your libraries specify a different stack alignment? I think this is the issue. Will let you know when I verify. In the future, would you prefer this sort of thing be restricted at compile-time to not run on chromium instead of reverted? We can't really leave a crash in. 799517 15 jamesr 2013-01-03 11:36:33 -0800 The issue is WebTransformationMatrix is aliasing space for WebCore::TransformationMatrix in different libraries without enforcing the same alignment requirements. This is an ugly hack that isn't needed any more, so I'll just make it not alias at all. This will take a little bit of time (probably not much more than an hour). Benjamin - feel free to reland this patch with the ASM version guarded behind !PLATFORM(CHROMIUM) if you want to land before I get around to this. 799533 16 benjamin 2013-01-03 11:58:36 -0800 > In the future, would you prefer this sort of thing be restricted at compile-time to not run on chromium instead of reverted? We can't really leave a crash in. I think #ifdefing Chromium would have been reasonable given this works everywhere except on that test. I was annoyed because the patch was reverted without any information. Dana promptly provided the missing pieces so I guess it's ok. > Benjamin - feel free to reland this patch with the ASM version guarded behind !PLATFORM(CHROMIUM) if you want to land before I get around to this. I'll wait a bit. It would be nice if Chromium could have the optimization too. I will land tomorrow if you don't come back to me. Ping me if I can help. I'll also add a #ifdef for FastMalloc. Stricto sensu, we cannot assume natural alignment on other allocator with malloc. 800623 17 181377 benjamin 2013-01-04 14:40:19 -0800 Created attachment 181377 Patch 800731 18 181377 benjamin 2013-01-04 16:35:12 -0800 Comment on attachment 181377 Patch Clearing flags on attachment: 181377 Committed r138866: <http://trac.webkit.org/changeset/138866> 800732 19 benjamin 2013-01-04 16:35:16 -0800 All reviewed patches have been landed.
