test-stringbytes-external-exceed-max-by-2.js and test-stringbytes-external-exceed-max-by-1-binary.js fail on arm pi2. They passed on the previous CI. I wouldn't have expected these to be flaky.

bnoordhuis · 2016-03-29T14:42:35Z

LGTM. No real suggestions for debugging the tests, I'm afraid. Perhaps check whether --gc_interval=1 makes a difference?

Rubber-stamp LGTM

I investigated the stringbytes test on the arm machines. It seems that they have indeed become flaky on the pi2 arm machines. With V8 5.0, the memory usage has changed subtly enough that common.enoughTestMem occasionally claims that we have enough memory to test, but an actual malloc done by ExternalStringTwoByte::NewFromCopy occasionally fails to allocate memory. Only the pi2 arm machines seem to be at this memory 'sweet spot' (or is it 'sour spot'?).

/cc @Trott because you have looked at flakiness of these tests in the past. One idea may be to adjust the threshold we use in common.enoughTestMem.

Trott · 2016-04-01T20:43:12Z

One idea may be to adjust the threshold we use in common.enoughTestMem.

That's probably the way to go unless/until someone has a better idea.

ofrobots · 2016-04-03T01:16:57Z

I have an idea to fix the flakiness of these tests, but I will have to move them to test/addons. Are test/addons ever run as part of the CI?

Trott · 2016-04-03T02:34:28Z

@ofrobots addons tests are run in CI on all platforms.

/cc @nodejs/build in case I'm misinformed.

correct: https://github.com/nodejs/node/blob/master/Makefile#L170..L172

The tests used to rely on precise timing of when a JavaScript object would be garbage collected to ensure that there is enough memory available on the system. Switch the test to use a malloc/free pair instead. Ref: nodejs#5945

Thanks. Here's a PR to fix the flaky tests: #6039. I will rebase once that lands.

It seems there is a wayward flaky stringbytes-external test-cases was lurking in the parallel directory instead of sequential directory that #6039 missed. 😭

Rebased after fixing the flaky test here: #6073. New CI: https://ci.nodejs.org/job/node-test-pull-request/2174/ is green.

@ofrobots ... as we discussed yesterday at the vm summit, will you be opening a PR to get v5 merged into master?

@nodejs/ctc ... @ofrobots and I spoke a bit yesterday about the possibility of getting v8 beta updates landed into master more regularly before they go stable so long as CI is green. Specifically, I'd like to get the v5 beta into the v6 release candidate that I'll be putting together on Monday.. so it would be fantastic if we can get v5 into master even tho it hasn't gone completely stable yet.
