21:01:47  <caitp>hey, is there any way to run bots from client.v8.ports on CQ tryjobs?
21:02:00  * bradleymeckjoined
21:04:06  <caitp>I end up with "Dry run: CQ has no permission to schedule in bucket master.client.v8.ports", but I really want to try the non-simulator ARM builder since testing this locally might take a few days
21:23:16  <aklein>caitp: hmm...I can try triggering that for you
21:23:33  <caitp>that would be appreciated if you can do that
21:23:40  <aklein>is that https://codereview.chromium.org/2645313003/?
21:24:21  <caitp>that's https://chromium-review.googlesource.com/c/445857/
21:24:45  <aklein>oh, hmm
21:26:18  <aklein>I think it may be that only trybots can be targeted with CQ_INCLUDE_TRYBOTS
21:26:48  <caitp>yeah
21:27:05  <caitp>I don't think there's a way to get at those builders I want from the cq
21:27:25  <aklein>yeah...this is a failure that only happens on real arm hardware?
21:27:36  <caitp>yeah, the simulator can't reproduce it
21:27:51  <aklein>boo
21:28:19  <aklein>ah this is the thing that's currently in the tree?
21:28:26  <aklein>(I haven't actually looked at the tree today)
21:28:50  <caitp>the patch causing the failure is still in the tree I believe
21:30:24  <caitp>I believe what broke the test is, -Infinity converts incorrectly/unexpectedly to int64_t on arm, so the bit that converts it to an index gets it wrong and it doesn't actually do anything
21:35:59  <aklein>where do you guess it's converting to int64_t?
21:39:30  <caitp>`start_from = static_cast<int64_t>(fp);`
21:39:42  <caitp>if fp is -Infinity, I think the result of that is undefined
21:40:44  <aklein>oo, yeah, that is not good
21:41:02  <aklein>I didn't realize ToInteger just left Infinity/-Infinity alone
21:41:09  <caitp>yeah it's weird
21:41:12  <caitp>kind of unexpected
21:41:58  <aklein>well leaving arm aside, it seems like you'd want to fix this code anyway, since I don't think you'd ever want to do static_cast<int>(-Infinity)
21:42:11  <caitp>for whatever reason, it seems to actually pass on x86/x64
21:42:21  <caitp>beyond me why it does though
21:43:18  <aklein>even your fixed code looks like it just casts Infinity to int64_t
21:43:24  <aklein>(though not -Infinity)
21:47:07  <caitp>you're right, it warrants another test case with +Infinity
21:47:08  <aklein>I wonder if it'd be more straightforward just to filter out negative and positive infinity altogether
21:48:02  <aklein>if it's -Infinity, you start at 0
21:55:43  <caitp>I have a feeling the +Infinity thing wasn't a problem, because a test case would have hit it if it were, but it's probably safer that way, so change made

22:46:09  * pinepainquit (Quit: Connection closed for inactivity)
22:58:28  <aklein>caitp: still lgtm (apparently I can't "+1" again()
22:58:58  <caitp>okay, I dunno if I should wait for anyone, probably better to have a fix in place
23:00:27  <aklein>caitp: would be nice to have the bots process this change rather than leaving the tree red
23:00:53  <aklein>I'm actually kinda surprised the tree's open
23:01:47  <caitp>you might be able to spawn a tryjob on client.v8.ports:gn_release_arm yourself, without running into the "no permission" thing
23:01:57  <caitp>but then again maybe not
23:02:24  <aklein>my suspicion is no
23:02:26  <caitp>I expect we'd know in a day or 2
23:02:33  <caitp>if it fixed the problem or not
23:05:11  <caitp>well, I'm going to see if I can reproduce the bug on igalia's arm device and see if the fix works there, I can land it before or after that
23:05:14  <caitp>what do you think?
23:06:13  <aklein>I would prefer landing now, we can always revert both this and the original patch if it doesn't fix the issue
23:06:20  <aklein>the code in the tree looks clearly wrong
23:07:26  <caitp>will have to revert 3 patches if it doesn't work, I think
23:08:09  <caitp>but hopefully that won't be needed
23:08:32  <aklein>I'd say the other option would be to revert the existing failing patches
23:08:41  <aklein>I wouldn't want to leave those ports busted for much longer
23:08:57  <aklein>otherwise we might end up with an Android Dev release with this broken
23:09:34  <caitp>yeah, not ideal, still probably not going to break the world for anyone
23:09:41  <caitp>anyways, we'll see
23:09:58  <aklein>I admit the scope is limited :)
23:16:05  <aklein>littledan___: sorry if I stepped on your toes re: removing natives
23:16:27  <aklein>I happened to decide to do it this morning after seeing PostExperimentals() output when I was trying to run with --print-bytecode :)
