Comment 23

[Cristina Coroiu [:ccoroiu]]

Since there is no reply, can we disable this test? If yes, to disable jsreftests can we use the same method as for reftests? I have searched in searchfox for ropes.js but no manifest found.

Joel, can you please advise?

Comment 24

[Jan de Mooij [:jandem]]

It's curious this also OOMs on 64-bit platforms so I looked into it. I wonder if the NoGC call here has something to do with it:

https://searchfox.org/mozilla-central/rev/92d11a33250a8e368c8ca3e962e15ca67117f765/js/src/builtin/TestingFunctions.cpp#1656

Steve, is there a reason this can't be just CanGC?

Comment 25

[Joel Maher ( :jmaher ) (UTC -8)]

:ccoroiu, jsreftests are much difference and this is the first time we have had a jsreftest fall into the disable-recommended list :)

We edit these in the source file, similar to this:
https://searchfox.org/mozilla-central/source/js/src/tests/non262/Array/regress-322135-02.js#1

you have to be very specific with the spaces used, just put the same line 1 in this file:
https://searchfox.org/mozilla-central/source/js/src/tests/non262/String/ropes.js

of course slow might need a different reason, I think OOM would be appropriate here. Lets see what :sfink replies with, maybe between :jandem and :sfink there will be a fix by tomorrow.

Oh, I bet you're right. I've been chasing my tail on this one, dumping out the counts of arenas and things because I wouldn't expect this test to use all that much memory (and it doesn't, locally.) I haven't managed to get an instrumented job to fail, and none of them use all that much.

My reasoning for making that call NoGC is that you can request a nursery-allocated rope by a configuration parameter. If it were CanGC, I reasoned that all of the ropes you wanted to be in the nursery would actually be tenured. But on second thought, if this needs to GC it will do that first, so the returned rope will be nursery-allocated. If you're in a loop, everything you previously allocated will now be tenured, but it seems like the alternative is to OOM.

When I wrote that, I imagined that NoGC meant "allocate whatever you need, even if you cross GC thresholds" (increasing peak memory usage but otherwise not affecting behavior). Instead, it seems to be "if you would normally GC, OOM instead." Honestly, my expectation seems like a better way for it to work -- an OOM because we're unwilling to expand the GC heap doesn't seem that likely to imply that we're truly at OOM. Filed bug 1532445 to discuss that.

For now, I'm going to go ahead and fix this as jandem suggested.
