Bug 78422 – Convert svg/animations to use SMIL methods for driving the timeline

• Component: SVG
• Status: RESOLVED FIXED

[Nikolas Zimmermann]

Convert svg/animations to use SMIL methods for driving the timeline.
This allows us to remove the home-brewn sampleSVGAnimationAtTime method from DRTs LayoutTestController, and the support code all around in SVGSMILElement & SMILTimeContainer.
Doing that, exposes two bugs in our SMIL implementation, that need to be resolved so that it works.

Chromium WebKit API change looks good to me.

FYIL new-run-webkit-tests svg/animations --randomize-order --iterations=100
All 9000 tests ran as expected.
I don't see any flakiness anymore, even with -g.
Note that this patch also doesn't need any rebaselines, it's all cross platform.

Seems like we should be able to do this in smaller (more reviewable) pieces.

This is covered by animate-path-nested-transforms.js & animate-mpath-insert.js.

> s/SVGANimationElement/SVGAnimationElement/
Fixed.

> Another bug report.. normally ;) Do you test them?
See above, both covered by svg/animations/ tests already.

Oh, that comment is outdated, will fix.

Point taken - but I already discussed with Dirk that he'll review it as-is.

Needs a follow-up change, for some last minute changes to lead to assertions in svg/animations/. Sorry.

Please ignore this failure for review, I'll skip it again, before landing, then check later on with the flakiness dashboard what's happening here. (The test is already marked as failing in trunk, I tried to revert it)

40s? Why not 4?

Why not 3.999?

Ditto.

Ah, your ChangeLog seems indeed be broken, why does it work with the other bots?

I don't think so - you'll never know though.

Well, prepare-ChangeLog is broken, I have to fix up the ChangeLog manually again.

Thanks.

Ah, I talked with Rob about this on IRC. The animation runs so quick, that 0.001s may result in quite large differences from the start value (eg. rect beginning, x=50, animating to x=5000 in 1s). So I raised the duration - to make it slower. It doesn't matter at all for testing - it doesn't make the testcase slower.

> Why not 3.999?
See above.

[Nikolas Zimmermann]

Style bot is still wedged - I will upload a new version anyway to turn cr-linux ews green.
