09:11 robertle_ I was trying to recreate a coredump from yesterday, but got a different one instead: https://gist.github.com/robertlemmen/7d71303ec38a0e0f3c7bb635de45dfa8
09:11 robertle_ this seems reasonably reproducible, let me know if there is anything I can do to help. it also hangs sometimes rather than crash, investigating that at the moment
09:12 robertle_ the program that crashes it basically just does HTTP::client queries to test a non-perl webserver
11:14 jnthn robertle_: What MoarVM version?
11:34 jnthn Though it doesn't matter much; either you have something that's not HEAD and upgrading will fix it, or you have HEAD and are doing stuff with Proc, in which case the rewrite of Proc in terms of Proc::Async that I'll do in the next days will fix it. :)
11:34 jnthn And the MVM_io_syncstream_write_bytes in that backtrace will cease to exist by the end of next week, all being well :)

13:04 eveo Any book recommendations to learn C and other bits to be able to hack on moarvm?
13:26 SourceBaby joined #moarvm
14:02 jnthn eveo: Well, the GC handbook (second edition) if you want to understand that side of things. I learned C many years ago from probably some earlier edition of http://shop.oreilly.com/product/9781565923065.do
14:03 jnthn Once you get to the point where you can look at something like `MVMCollectable ***foo;` and not be intimidated by the indirection, you're probably good. :)
14:04 domidumont joined #moarvm
14:14 eveo Thanks
14:14 yoleaux 13:19Z <araraloren> eveo: thanks, I just make a type mistake. It's fit what I thought.
14:22 jnthn Any particular bits of MoarVM you're looking to learn about?
14:34 zakharyas joined #moarvm
14:40 eveo Everything.
14:53 nine ah, the famous three stars in the signature. I remember the blog post :)
15:04 jnthn If you're writing a moving GC you're gonna end up as a 3 star C programmer
15:05 jnthn Given in involves having lists (1) of locations (2) of object references (3). :)
15:05 jnthn eveo: You may also want to read some of the 6buts bug-hunting posts too and try to follow them in the MoarVM source :)
15:05 jnthn *6guts
15:05 jnthn .oO( 6 butts )
15:06 eveo Thanks. I will.
15:06 jnthn Darn, it was hot enough in my apartment before I made cottage cheese...
15:07 lizmat 29.7 highest here today
15:08 lizmat getting some thunderstorms / rain now
15:08 jnthn 28ish here
15:08 lizmat inside we're still at 23 :-)
15:08 jnthn I normally just use halloumi instead of making paneer. The texture's kinda right and I quite like the added saltiness.
15:09 jnthn Alas, couldn't get hold of it.
15:09 jnthn It's got to 26.5 in here.
15:09 jnthn South facing apartment is lovely and bright...but not so great on a hot sunny day
15:10 jnthn At least I do $dayjob at an office now and that stays some degrees cooler than here :)
15:12 timotimo i don't have a thermometer in here, but a sign on the road said 34 degC an hour or two ago
15:13 jnthn ugh
15:15 ggoebel joined #moarvm
15:29 geekosaur joined #moarvm
15:44 timotimo granted, that sign might have read the temperature above the road, which was asphalt, which famously becomes pretty hot when the sun shines on it

17:32 robertle_ jnthn: my crashed moar was 2017.05-29-g68620c8e, but if this is in a codepath that is going away then great! I'll be running this type of code in test cases for a while, so I'll see how it goes...
