Closed Bug 801562 Opened 9 years ago Closed 8 years ago
DOM says to. Worth a try?
This should land after bug 773780 to avoid bitrot. I'll still write the patch now while I have time, and update it later.
Depends on: 773780
Summary: Remove .isSupported → Remove Node.isSupported
The diffstat made me an immediate convert: 42 files changed, 1 insertions(+), 3484 deletions(-) Granted that it's almost all test files -- but still, they're horribly ugly tests and I'm delighted to be rid of them. A few more test changes might be needed. Try: <https://tbpl.mozilla.org/?tree=Try&rev=3f35951f7d8c> The one line inserted is because of js/xpconnect/crashtests/468552-1.html. Bug 468552 happened to use isSupported to test for an XPConnect bug -- I switched it to replaceChild instead, on the theory that it should be testing the same basic bug.

For the moment perhaps the SVG mochitest should stay but use hasFeature instead and only test SVG features. That would still allow you to get rid of isSupported wouldn't it?
Given that even removing navigator.taintEnabled() (Bug 679971) caused major problems, I'd be very careful removing this stuff. We need to have at least some data whether it is being used. So, please add first some telemetry probes.

I had to rewrite the patch to apply on top of the current tree, because IsSupported implementations have moved around a bunch. It builds locally and passes some tests I tried. I also adjusted the SVG test to use hasFeature instead of deleting it. The basic idea is identical to the previous patch. Try: https://tbpl.mozilla.org/?tree=Try&rev=4c0a12849b8f
