| dogbert2 | it's very silent around here | 11:02 | |
| lizmat drops a pin | 11:03 | ||
| brrt | not everyday can be a party :-) | ||
| brrt has just looked at the source code for libuv, and is less-than-excited of replicating that for the sync IO ops | 11:17 | ||
| so I guess the tc loop structure is here to stay :-) | |||
| dogbert2 | are you working on your fork branch? | 11:30 | |

| brrt | dogbert2: well, if you find anything, be sure to let me know | 13:38 | |
| dogbert2 | brrt: I haven't found anything, perhaps my mind is playing a prank on me :( | 13:52 | |
| perhaps jnthn remembers | |||
| jnthn | On postrelease-opts, there are some SEGVs now and then in spectest that go away with MVM_JIT_DISABLE=1 | 13:55 | |
| jnthn wonders if gist.github.com/dogbert17/2d499ec5...9c7db6107b is still relevant/happening | 14:06 | ||
| brrt | jnthn: say no more, i'll investigate :-) | 14:09 | |
| or mabe say more | |||
| jnthn | Well, MVM_SPESH_BLOCKING=1 makes them go away, so argh. | ||
| Or it was a lucky run. | |||
| brrt | oh... | ||
| hmmmm | |||
| jnthn | Since I was getting them only sometimes | ||
| diakopter | or it was unlucky both times | 14:10 | |
| jnthn | I've also got one that shows up reliably under blocking but only with JIT disabled...wow. | ||

| dogbert2 | jnthn: I can retry the postrelease-opts branch when I get home | 14:32 | |
| jnthn: also I found something odd in master, i.e. github.com/MoarVM/MoarVM/issues/960 | |||
| jnthn | ooh, interesting | 14:35 | |
| brrt wonders if ASAN makes them more reliable | 14:40 | ||
| jnthn | Well, latest spectest run was fine, and the last faily one (with JIT) was some days ago... | 14:55 | |
| jnthn doing another run now | |||
| oh, no, yesterday | |||
| But still, rebuilt everything sience | |||
| *since | |||
| timotimo | btw we don't have hllbool and hllboolfor in facts.c | ||
| jnthn | And a second clean run | 14:57 | |
| (this is with postrelease-opts) | |||
| dogbert2: I think the DU chain fail is due to a mistake in the hllboolfor opt | 15:03 | ||
| dogbert2 | jnthn: aha, that makes sense, i.e. I was certain that it had been eradicated from postrelease-opts | 15:04 | |
| jnthn | Well, it's there too now, because I rebased onto master :) | 15:06 | |
| dogbert2 | as for postrelease-opts, you enabled a new check there for SC-index. I guess that bug hasn't been fixed yet? | ||
| it was possible to trigger that check with e.g. gist.github.com/dogbert17/24e6033e...c8cfdfb444 | 15:07 | ||
| jnthn | Did you manage to get that bug to happen on master too? | 15:10 | |
| dogbert2 | haven't tried | 15:11 | |
| I guess I'll have to move that commit to master first | 15:13 | ||
|
15:14
patrickb left
|
|||
| jnthn | Hmm, no commit reports here? | 15:16 | |
| Anyway, github.com/MoarVM/MoarVM/commit/7a...96e7634d89 | 15:17 | ||
| dogbert2 | jnthn++ | 15:19 | |
| jnthn | I can repro gist.github.com/dogbert17/24e6033e...c8cfdfb444 one in every few runs | ||
| brrt | yay, i guess :-) | 15:20 | |
| this is JIT sensitive? | |||
| jnthn | Nope, shows up with MVM_JIT_DISABLE=1 | 15:21 | |
| brrt | oh, hm.. | ||
| jnthn | However, I can't get it to happen with MVM_SPESH_DISABLE=1 | ||
| Not in many, many runs | 15:24 | ||
| Nor with MVM_SPESH_INLINE_DISABLE=1 | |||
| dogbert2 | perhaps a smaller nursery might help | 15:25 | |
| jnthn | Well, or it's inlining related ;) | ||
| dogbert2 | any theories? | ||
| jnthn | Need some more data yet | 15:26 | |
| timotimo | i have a discovery bit for hllbool | 15:28 | |
| but hllboolfor would also be interesting, surely | |||
| jnthn | tssk...can't get it to fail any more | 15:29 | |
| brrt | jnthn: maybe jit-bisect.pl --spesh helps | 15:30 | |
| dogbert2 | jnthn: I just remembered that I had (almost) golfed the problem: gist.github.com/dogbert17/23b5e847...c582760963 | 15:38 | |

| dogbert2 | if it is indeed the same one | 15:38 | |
| dogbert2 changes location & | 15:39 | ||
| jnthn | I think it's the MVM_CF_REF_FROM_GEN2 addition | 15:44 | |
| diakopter | I do not understand what in the world they are talking about on #perl6 .. some rakudo fork they want to be an alternative alias in the debian packages? | 15:52 | |
| jnthn | Darn it, thought I'd got a fix, but no... | 16:00 | |
| [Coke] | not a fork. | 16:02 | |
| being able to call an installed rakudo with either `rakudo` or `perl6` instead of just `perl6` | |||
| ilmari | I think the point is to be able to choose which perl6 implementation gets to be /usr/bin/perl6 | 16:15 | |

| Geth | MoarVM/postrelease-opts: 9e90cdd6ce | (Jonathan Worthington)++ | 2 files Don't set ref'd from gen2 flag during GC Parallel GC relies on us only updating the object flags from the thread that owns the object (or the nominated thread to GC that thread's objects). The updates caused by the write barrier touching the object that was referenced caused races that could lead to incorrect GC behavior, which typically showed up as an invalid SC (which was really because the forwarder lives in the same slot that the SC used to on a moved object). |

| dogbert17 | are there any other problems left on this branch after this fix? | ||
| jnthn | No idea :) | 16:49 | |
| If there are, I don't see them in spectest :) | |||
| dogbert17 | cool | ||
| jnthn | I should try it out on $big-customer-application | ||
