946069 - 10.9 is very angry about use of an invalid context in test_canvas.html

Status: RESOLVED WORKSFORME

(Core :: Graphics: Canvas2D, defect)

Description

[Phil Ringnalda (:philor)]

Not going to be much fun to fix if it doesn't repro locally, because we have 10.9 test enabled only on Cedar, and we have exactly one test slave to run them.

This remains a consistent problem in 10.9 runs on Cedar, on both Opt and Debug:

This (or a very similar problem) is still happening with 

Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:33.0) Gecko/20100101 Firefox/33.0

Firefox 33.1.1 from DMG from website, on a freshly installed OS/X 10.10.1 Yosemite

I'm getting it in the system.log during normal web browsing.  If someone thinks it's based on a different cause, let me know, and I will open a separate bug for it.

[Milan Sreckovic [:milan] (needinfo for best results)]

So... what is the action in this bug?  Taking care of all the CGContext... messages from comment 0?  Or taking care of the unexpected fails in the tests from comment 1?  Or taking care of the messages from the tests that passed (e.g., "Nonzero value at position 2...")?

Attachment: Check if the CG context is valid before calling methods on it.

Comment 6

[Markus Stange [:mstange]]

Have you been able to reproduce these warnings? Do you know under which conditions they appear?

So your patch protects two different kinds of contexts from being accessed when null: The main DrawTargetCG mCg, and the temporary UnboundednessFixer CGLayer mCg. For the former, I'd prefer if we'd just return false from DrawTargetCG::Init when mCg is null, so that the Factory just returns null instead of a broken DrawTarget. For the latter, we could just return baseCg from the fixer - this just means that the output will be slightly wrong (because the stuff around the draw bounds won't be affected), but only in the case where we failed doing the right thing. Jeff asked for a similar thing in bug 951443 comment 2. Though in that case returning baseCg meant that the result would still be correct...

Let me look at these suggestions.

None of these trigger on 10.6, but we already knew that :) https://treeherder.mozilla.org/ui/#/jobs?repo=try&revision=1266a1370766

Attachment: Assert and annotate crash report if we run into invalid contexts. Also check for empty path before asking for a current point. r=mstange

Non withstanding changing the code so that we can't run into invalid contexts, adding some error messages if that does happen (bug 1101685 adds the asserts as well.)  We can then see if this still happens and take Markus' suggestion to fix the code so that it doesn't.

Review of attachment 8535799 [details] [diff] [review]:
-----------------------------------------------------------------

I'm not really sure what the mCg checks are achieving. mCg is initialized in DrawTargetCG::Init and never changed from that point on. Wouldn't it be enough to check mCg at the end of DrawTargetCG::Init (only if Init returns true)? Or are you trying to protect against callers that call DrawTargetCG functions without having called Init on it?

Comment 11

[Milan Sreckovic [:milan] (needinfo for best results)]

Not really trying to protect at this point, trying to get more information as to what happens on Cedar, given that I don't see it locally.

Part of this run: https://treeherder.mozilla.org/ui/#/jobs?repo=try&revision=f04a366bfe8f

Let's leave this open after this patch, as we're really trying to see what happens on Cedar and if it can point us to the underlying problem.

For the record (re comment 2): autoupdate to 34.0.5 on 10.10.1 seems to have cleared up *my* version of this error message problem, at least.  Thanks to whomever did the work.  Leaving CC.

Phil, can you check if the original problem still happens?

Comment 18

[Phil Ringnalda (:philor)]

No, I can't. Releng got bored with running 10.9 on Cedar with absolutely nobody looking at fixing the failures seen there, so they gave up, we aren't ever going to run tests on 10.9, and they are starting in on 10.10 instead, but they haven't yet gotten far enough along to have tests actually running yet.

Comment 19

[Milan Sreckovic [:milan] (needinfo for best results)]

OK, let's see what happens in 10.10

Comment 21

[Milan Sreckovic [:milan] (needinfo for best results)]

There is one place where DrawTargetCG::Init fails in this run. However, there are no complaints about us attempting to use it, so maybe we just close this one for now.

(In reply to Markus Stange [:mstange] from comment #10)

I didn't open a bug for this, but it's a valid suggestion.
