1000722 - Many B2G reftests fail after enabling OOP, because partial drawWindow calls are drawing too small an area

Status: RESOLVED FIXED

(Testing :: Reftest, defect)

Description

[Vincent Chen [:vichen]]

Follow: Bug 922680 Comment 106
After enable OOP on B2G reftest, there are many reftests fail. After regress among patches (http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=5405d6f4e3c6&tochange=92dd49bd29b6), the fails is between the two patches.

Pass: Apr 15 13:08:13 92dd49bd29b6 https://tbpl.mozilla.org/?tree=Try&rev=d097b88f2b72

As the patches between d823e000d59c and d097b88f2b72 are submitted by you, would please check first.

Comment 3

[David Baron :dbaron:]

Those patches re-enabled a feature of the reftest harness that was accidentally broken; see bug 995410.  With that bug fixed, the reftest harness again uses partial drawWindow calls to redraw only the invalid region, instead of redrawing the entire screen.

The other bugs in that range (bug 995661 and bug 995721) fixed bugs where partial-window drawWindow calls were broken.  It looks like this set of failures shows another way in which a partial window canvas drawWindow call is broken.  Many of the failures in comment 0's "Fail" line are the same tests that I saw on other platforms when testing bug 995410 without bug 995661 or bug 995721.

In this case, the problem looks somewhat different from bug 995661 and bug 995721, though.  It appears that the area being redrawn is slightly too small.  (layout/reftests/transform/dynamic-addremove-1a.html is perhaps a good example test to debug; it's one of the failures in R15.  It shows failures around the edge of the box that moved, and also around the edge of the window.)

Comment 4

[David Baron :dbaron:]

Bug 1018381 seems to cover the same problem as this bug.

Comment 5

[David Baron :dbaron:]

Also, bug 922680 comment 97 links to some useful history on how we got to this point, I think.

Comment 6

[Andrew Halberstadt [:ahal] (PTO Until Apr 3rd)]

Once this is fixed we should re-enable all the tests that were disabled by bug 981477 and re-triage them on try. To do that we can backout all the patches that landed in that bug, which in order they should be backed out in are:

Comment 9

[u459114]

update what I found so far.

By looking over comment at bug 100722 and bug 1018381. Here are actions:
1. Remove all "random-if" failure type in tests/layout/reftests/flexbox
2. submit a try run
   Try result: https://tbpl.mozilla.org/?tree=Try&rev=f7c9eef86098
3. Many failures(because of #1). I think flexbox-dyn-changePadding-1a is 
   really trivial one. Look into this failure first.
   Pass criteria: == flexbox-dyn-changePadding-1a.xhtml flexbox-dyn-changePadding-1-ref.xhtml
4. Look into TEST-UNEXPECTED-FAIL of flexbox-dyn-changePadding-1a.xhtml
   https://tbpl.mozilla.org/php/getParsedLog.php?id=41871625&tree=Try&full=1#error4

   From the log:
   06:44:40     INFO -  REFTEST INFO | Saved log: [CONTENT] Rect: 8 8 108 108
   
   I "think", if the value of Rect change to  {8, 8, 110, 110}, thing should goes right.
   There is no build env at home. Need to confirm this assumption after entering 
   office tomorrow.

   Rect value is set here:

Comment 10

[u459114]

My description in comment 9 is not correct.
Size of <div id="tweakMe"> is (100, 100)

06:44:40     INFO -  REFTEST INFO | Saved log: DoDrawWindow 8,8,100,100
ctx.drawWindow(gContainingWindow,8,8,100,100,"rgb(255,255,255)", gDrawWindowFlags);

Size of this drawing is correct. Need look into gecko side to figure out why 2 pixels miss on right/ bottom boundary of <div id="tweakMe">

It would be good to dump the root frame during the drawWindow call.
You can define DEBUG_FRAME_DUMP from [1] and add "rootFrame->DumpFrameTree()" before [2].

Hi dbaron,
I think the problem cause by padding of remote-iframe, which is created in OOP case only. 
After applying attachment 8441998 [details] [diff] [review] and attachment 8442002 [details] [diff] [review], all test cases in flexbox passed at local side.

Please help to review this patch, thanks

Most Red color are caused by turning on frame tree dump

r=dbaron.  Thanks.

(It seems a bit curious that this causes a problem only for the OOP case, though.)

Once this is landed, the random-if() and skip-if() annotations due to this bug should also be removed.

Perhaps that's because there's a bug in a codepath used by drawWindow that's incorrectly subtracting this offset?

That's a thing that I am going to figure out.
I suspect that is because default css value of iframe and xul:browser is different 
OOP
  gBrowser = gContainingWindow.document.createElementNS(XHTML_NS, "iframe");
Non-OOP
  gBrowser = gContainingWindow.document.createElementNS(XUL_NS, "xul:browser");

This patch does not merge correctly. That's why it causes bug 1027501. However bug 1027501 is a potential error, it still needs to be fixed.

Hi ahal,
Back out these four patches re-enable many failed test cases which are not fixed yet. For example, XUL test case and font-inflation ones.

I am going to roll back these four patches and manually disable failed ones in this bug, may I have your opinion here? Thanks.

Yes I think that's the best way to do it. Though you might as well land part 1 now (assuming it doesn't cause any orange).

Unfortunately, it does cause some orange.
For example, these four reftest failed
fails-if(B2G&&browserIsRemote) == tablespacing-4.html tablespacing-4-ref.html
fails-if(B2G&&browserIsRemote) == tablespacing-5.html tablespacing-5-ref.html
fails-if(B2G&&browserIsRemote) == tablespacing-5a.html tablespacing-5a-ref.html
fails-if(B2G&&browserIsRemote) == tablespacing-6.html tablespacing-6-ref.html

I need to remove some "fails-if(B2G&&browserIsRemote)" before check in this patch.

I assume these were here before? Otherwise are you sure it fails in the non-oop case too?

Looks like "Part 1" also fix this bug. I am going to remove fails-if

Bug 906716 - Intermittent B2G emulator "timed out after 1000 seconds of no output"
I never meet this problem in my office time. I don't this failure is relative to applied patches

Awesome! For future reference, you can re-trigger a job without doing a new push by clicking the blue '+' in the bottom left (after first clicking a job). I went ahead and re-triggered the jobs on the previous push a few more times.

That looks really green! I think we are good to land.

MozReftestInvalidate fired and invalidate area is correct.

This fail is not relative to Part 1. 
Part 2 remove random-if failure type cause this problem.

Hi Ahal,
REFTEST TEST-UNEXPECTED-FAIL | http://10.0.2.2:8888/tests/layout/reftests/svg/outer-svg-border-and-padding-01.svg | image comparison (==), max difference: 255, number of differing pixels: 10000
Return code: 1

Before we have attachment 8442612 [details] [diff] [review], this test is 100% fail. After that, this test case turn out to be random failed.
I prefer change failure type back to random-if and file another bug to fix this timing issue, how do you think?

[Andrew Halberstadt [:ahal] (PTO Until Apr 3rd)]

That sounds good to me. Better to land this before more stuff breaks on us.

This is generally green on Aurora, but it's hitting timeouts in dynamic-use-02.svg ~20% of the time. I'm not sure if it's a consequence of tests shuffling around between chunks or something else, but it's interesting to me that it's not hitting trunk AFAICT.
