test timer flood scenario
We should add a timer flood test in order exercising the improvements from bug 1300659. This code is too fragile and could easily regress in the future without a test running in automation.
This tests that we can load iframes, perform network requests, and requestAnimationFrame() calls during a timer flood. Try build with test on current tree: https://treeherder.mozilla.org/#/jobs?repo=try&revision=09b55c260f590845da700e3ebb3f664f087fe2c2 Try build with test on tree with bug 1300659 effectively backed out. This should show that the test times out or crashes without our timer improvements. https://treeherder.mozilla.org/#/jobs?repo=try&revision=925d3869763b96eeccb35ed9e1b76e5df41185a9
Comment on attachment 8814283 [details] [diff] [review] Test that the browser continues to function during timer floods. r=bz Boris, can you review this test? It basically triggers an exponential timer flood and then tries to do various things: 1. Load some frames 2. Perform some network requests 3. Run some requestAnimationFrame() callbacks The previous try runs show this passes with current tree, but times out without the anti-flood timer patches (that have already landed).
Comment on attachment 8814283 [details] [diff] [review] Test that the browser continues to function during timer floods. r=bz r=me but maybe add a comment about running rAF for 5s in the line that does the 5*60 bit?

Added comments. Also, I switched the flood window to be a child iframe. I don't want this test to suddenly work just because separate windows are in a different process, etc. I discussed this with Boris in IRC and he was ok with it. New try: https://treeherder.mozilla.org/#/jobs?repo=try&revision=db8b2cc548ab89eb9976059ab6df38e2b57f38fc Try with timer flood protections removed: https://treeherder.mozilla.org/#/jobs?repo=try&revision=44ec12461b8229db1f620be95ba2e579b9c1c39e

Since bug 1300659 landed on FF52 I uplifted the test as well: https://hg.mozilla.org/releases/mozilla-aurora/rev/3fa3896980f6726c3897ce1645a839996d5d5e8b
