donaldh_ jnthn: when is the right time to lookup hll types for async callbacks? 09:16
jnthn: is it okay to look them up when the async call is made?
09:16 ClarusCogitatio joined
donaldh_ jnthn: This is nqp, jvm backend. 09:16
jnthn donaldh_: I'm not sure that MoarVM bothers; it just uses BOOTInt etc and relies on the hllize mapping taking place in the language. 09:18
donaldh_: We'd have to capture the hll at the time the task is started, though.
And keep it around for the callback.
donaldh_ yep
jnthn Which is why I wondered if we can get away with it. Turns out yes ;) 09:19
donaldh_ currently using curTC.curFrame.codeRef.staticInfo.compUnit.hllConfig
but codeRef is sometimes null 09:20
jnthn Right, it will be
'cus the thread that gets the callback may just be any old Java thread, not one we're running code on.
donaldh_ yep. So switched to looking up types when async call is made. 09:21
But you suggest just using BOOT types?
jnthn yes 09:23
Well, at least, I know it works to. :)

timotimo how intelligent is our ThreadPoolScheduler, btw? 12:34
moritz more than me.
timotimo :D
there could probably be some "work stealing" stuff to do with semaphores/locks, right?
as in: we've just started blocking on this lock, here's a thread that's holding the lock, but is currently not being executed 12:35
in that case we should be able to just jump to that thread and execute it, perhaps just until it releases that lock, perhaps until it gets interrupted for whatever reason
is there something clever we can do when one thread has gone to sleep? do we have to keep that thread on the given task to ensure the sleep ends without a terrible delay? 12:36
and i still didn't get an answer how to cancel a computation that's not "cooperating" 12:47
like if you accidentally write an infinite loop in the golf-helper

[Coke] rakudo.jvm & rakudo.moar both have failing tests. 13:28
(all of them in S17)
(jvm looks like simple failures, moar is aborting) 13:29
13:29 FROGGS left
[Coke] colomon: niecza is now failing 575 tests. 13:29
(lots of aborts there, though, should be an easy cleanup) 13:30
lizmat [Coke]: S17 tests should not abort 13:31
they should just fail 13:32
because they point at a real problem wrt to Supply.delay and Supply.stable
I haven't "skipped" them
I hope jnthn and/or me can find the source of the problem 13:33
which seems to be that the feeding supply is passing on a "done"/"close" without delay, thereby causing values to disappear
eyes / suggestions welcome
13:34 btyler left
timotimo hmm 13:35
one could probably instrument the debugger backend so that it'd echo every executed line with a timestamp and thread id 13:36
and then reconstruct a timeline annotated with the source lines?
13:36 btyler joined
moritz and influences the execution, because at some point, the thread's accesses to STDOUT have to be serialized 13:37
13:37 kaare_ left
lizmat yeah, heisenbugs :-( although I don't think this one is, though 13:38
it's pretty reproducible
13:39 lvfjf joined 13:43 btyler left
[Coke] lizmat++ btw for trying to fudge older implementations on newer tests. 13:44
lizmat: github.com/coke/perl6-roast-data/b....out#L1488 13:45
here's a message hidden in moar's output: S29-os/system.rakudo.moar..........................execvp(): No such file or directory
integration/advent2013-day14.rakudo.moar...........Aborted (core dumped)
timotimo moritz: they could output to one file per thread 13:48
that should solve the problem, no? 13:49
jnthn timotimo: picking appropriate threads with regard to locks and semaphores is the job of the OS scheduler. 13:50
timotimo: If you call sleep, you block a thread. End of story. A sleeping thread is quite cheap GC wise though, in that you knwo you don't have to wait for it, and it is producing no garbage. 13:51
timotimo: the sane way to deal with uncooperative threads is to use processes instead, or at least another VM instance that you can have full control over. 13:52
lizmat: I got those failures on my laptop too, so will be able to look at them a bit. 13:53
lizmat: Either tonight or tomorrow.

timotimo jnthn: so the golf-helper should likely use a subprocess, perhaps with a ulimit or with a kill after a timeout? 13:58
i suppose a kill would be easiest 14:00
jnthn timotimo: "should" 14:01
timotimo: All systems have to be seen in a context. This isn't exactly mission critical. :) 14:02
But for something that needed to support cancellation of arbitrary code robustly - yes, you'd want a process-based solution. 14:03
I wonder how nicely we can provide taht already
14:04 thou joined
lizmat a Supply reading from STDIN in some way ? 14:04
jnthn phew....teaching done
lizmat: Not sure; maybe 14:05
timotimo jnthn: it's unfortunately far too easy to execute infinite loops when you're golfing, as you'll very often be using lazy (infinite) lists in that context
hence my concern
the migrate combinator closes its "superfluous" taps, right?
14:05 btyler joined
jnthn Right, so you'd want the closign of the tap to terminate the process here. 14:05
timotimo that seems like a useful primitive actually 14:06
14:06 anaeem1 joined
jnthn lizmat: Certainly it wants to be a supply that is done on success. 14:06
timotimo a tap from any subprocess that automatically kills the subprocess when all taps of it are closed
jnthn I suspect it's a demand-supply
timotimo what should i look at (for copying purposes) if i want to build a tap that noms from any given file? 14:07
14:09 xenoterracide joined, molaf joined 14:10 anaeem1 left, xenoterracide left
jnthn timotimo: are you looking to implement async file I/O? 14:12
If so, see asyncsocket.c in Moar, and IO::Socket::Async. 14:13
timotimo oke :)
well, i'd like to have tap-based stdin :) 14:14
jnthn That sounds...curious.
That'll also be tricky at the moment, I suspect...
timotimo if i have a console-based game, i need some way to have a non-blocking read on stdin anyway 14:15
not sure if there's something for that yet?
jnthn How is that usually handled? getkey?
timotimo i suppose so? 14:16
jnthn I dunno, I dont' write console games :P
timotimo i'll likely have something like an event loop that will coordinate with ansi escape codes
is there something in rakudo already that'll let me try to get one byte from stdin and if there's nothing immediately returns?
jnthn Don't think .getc will do that, no 14:17
timotimo some way to ioctl the file descriptor into a nonblocking state? 14:18
(except NativeCall)
jnthn Not so far as I know.
Nobody implemented it yet. I guess tadzik++'s games use SDL which handles such things, so those didn't block on it 14:19
I need to head to the station...

colomon so, one more reason I need to get my own git server up and running. :) 15:33
colomon has been eyeing gitblit
timotimo fortunately it's very easy; if you connect via ssh, you can start with no installation at all
TimToady I use: shell "stty raw -echo min 1 time 1 </dev/tty"; 15:34
timotimo that's your git server? :) 15:35
TimToady then to read chars: push @INPUT, $TTY.read(1)[].chrs unless @INPUT;
that guarantees at least one more char in @INPUT 15:36
os it is possible to do single-char input, at least on unixoids
*so 15:37
15:38 zakharyas left
TimToady oh, and $TTY is an opened /dev/tty 15:38

timotimo yeah, niecza++ seems kinda unbeatable, at least for the time being
TimToady but then, niecza kinda cheats, which is one reason it was abandoned
masak cheating is technique.
Ven_ cheating is waiting for the right design to come to mind :) 15:49
masak the right design gets to cheat too, as long as it doesn't get caught :)
Ven_ if it's the right design, it's not longer cheat 15:50
In what way does niecza cheat, anyway ?
15:55 kaare_ joined
TimToady is too senile to remember the specifics 15:58

and this well also produce the result 2?
jnthn why the list? 18:31
timotimo FROGGS: it seems like it can be an op if with two Wants or IVals in it

FROGGS I thought I'd need the list to have both in the condition

donaldh jnthn: What's the expected behaviour for asyncreadchars when a client drops the connection (IOException: Connection reset by peer on JVM) 22:30
jnthn: should that be put on the queue as an error and a seq -1 ? 22:31
jnthn Is that an orderly connection close, or an actual error? 22:32
If it's the former, then it probably wants to send -1 but not an error string, which can indicate "done" in the supply, I guess. 22:33
donaldh I don't think it is an orderly close.
jnthn ah, then yes, error 22:34
Connection reset by peer doesn't sound orderly to me... :)
