| brrt | good * #moarvm | 08:26 | |
| chrisseaton.com/rubytruffle/jokerconf17/ did anyone read this? | 08:27 | ||
| i thought it was pretty cool | |||
| about graal | |||
| so, two more random thoughts | 08:36 | ||
| - i still want to reduce the node size for the expression nodes to 32 bits, and | 08:37 | ||
| - i want to encode the number-of-args in an operator directly in the operator | |||
| so i can use the lower 16 bits as the operator and the upper as the number-of-args and maybe some other flags | 08:38 | ||
| maybe [operator (16), argnum(8), flags(8)] | |||

| dogbert2 | jnthn: how's the cold? | 10:53 | |
| jnthn | Clearing up, thanks, though I still feel oddly tired | 11:08 | |
| dogbert2 | running perl6 -e '' leaves 13 fd's open according to valgrind # guess that's ok | 12:43 | |
| running perl6 -e 'await (^5).map({start { say qqx{echo -n foo $_} } })' leaves 54 fd's open # is that to be expected ? | 12:44 | ||
| lizmat | dogbert2: maybe that includes threads ? | 12:48 | |
| and the handles for async stdout/stdin/stderr | 12:49 | ||
| dogbert2 | probably | ||
| lizmat | you could try an END { nqp::force_gc } and see if that makes a difference | 12:50 | |
| dogbert2 | but shouldn't they be cleaned up at some point or is the OS supposed to do it | ||
| ilmari | the OS cleans it up at exit, of course | ||
| dogbert2 | lizmat: like this ? 'use nqp; await (^5).map({start { say qqx{echo -n foo $_} } }); END { nqp::force_gc }' | 12:54 | |
| ilmari | it's a bunch of pipes and eventpoll and eventfd handles | ||
| paste.scsys.co.uk/565690 | 12:55 | ||
| lizmat | dogbert2: yeah that looks like it | ||
| dogbert2 | ilmari: couldn't this become a problem for a more long running, heavily threaded prg | ||
| lizmat: Unhandled exception: getexpayload needs a VMException, got P6opaque (X::AdHoc) | |||
| lizmat | whee! | 12:56 | |
| dogbert2 | :) | ||
| lizmat | that happens if you get an exec error in an END block | ||
| I guess we need some catcher there | |||
| dogbert2 | lizmat: tried this before 'await (^5).map({start { say qqx{echo -n foo $_} } }); say "test"' I got the impression that the program hang always came after having written "test" | 13:00 | |
| highly unscientific ofc :) | 13:01 | ||
| it's like the code suddenly fails to terminate properly | 13:03 | ||
| Zoffix | Wasn't that one golfed down to a nqp proc assync start op? | 13:05 | |
| dogbert2 | does anyone happen to know how to get debug symbols for stuff like /lib/i386-linux-gnu/libc.so.6 and /lib/i386-linux-gnu/librt.so.1 | 13:06 | |
| Zoffix: did I miss that ? | |||
| Zoffix | dogbert2: github.com/rakudo/rakudo/issues/12...-339720430 | 13:07 | |
| dogbert2: that was found by sticking debug prints and seeing where it hangs and eventually it showed it hangs on nqp::spawnprocasync op | 13:08 | ||
| dogbert2 | aha, cool | ||
| dogbert2 tries the example | |||
| the annoying thing, for me at least, is that I only get hangs when I want SEGV's :) | |||
| Zoffix: you code hangs after a while like you wrote. If I leave it hanging I find 400+ lines, when running ps auxww, with the text '... [echo] <defunct>' | 13:12 | ||
| heh, the code only seems to hang, in fact it continues to run albeit superslow | 13:18 | ||

| samcv | how do i induce crashes | 19:49 | |
| i tried to get t/spec/S32-str/CollationTest_NON_IGNORABLE-3.t and t/spec/S32-str/encode.t to crash but couldn't even running them on loop | |||
| also tried setting MVM_SPESH_NODELAY=1 and MVM_SPESH_BLOCKING=1 anything else i can do? | |||
| nine, said he saw them under heavy load, but i have 8 threads so i guess i could try to do that but | 19:50 | ||
|

cognominal joined
|
|||
| samcv | sounds like a pain is there an easier way | 19:50 | |
| timotimo | you can reduce the size of the nursery in src/gc/collect.h, and you can crank up the memory debug in src/gc/debug.h or what it was | 19:54 | |
|

| btw, the same valgrind complaint shows up in t/spec/S32-str/CollationTest_NON_IGNORABLE-3.t as well | 21:29 | ||
| samcv | dogbert17++ | 21:38 | |
| thank you | |||
| dogbert17 | hi samcv | ||
| MasterDuke | samcv: fwiw, i saw a fail in t/spec/S32-str/CollationTest_NON_IGNORABLE-3.t yesterday during one of my many spectest runs, but didn't try to reproduce | ||
| samcv | others have been seeing it but i haven't been able to reproduce locally. but if there's valgrind issue that will make it much easier | 21:39 | |

| Geth | MoarVM: 11b12a268e | (Samantha McVey)++ | 2 files Fix uninitialized variable access in MVM_unicode_get_property_str With the more recent changes the variable doesn't get set if the codepoint is unknown. Make sure we initialize it so we don't get any segfaults or other issues. |
