00:06 adu joined
timotimo i managed to get the not and prefix:<!> code much, much tighter 00:07
could be a tiny bit better, but i'll take the current improvement 00:08

bbkr what should I do when I randomly get segfaults or other errors when using Promises on HEAD rakudo-moar? for example: gist.github.com/bbkr/28e8fd7c90344f4ae6b7 00:41
00:42 ajr_ left
timotimo perhaps see if the problem goes away by setting MVM_SPESH_DISABLE or MVM_JIT_DISABLE in your environment 00:43
so that we can see if jitting/speshing makes things worse or doesn't impact it
bbkr trying it now..
00:43 rurban joined
JimmyZ bbkr: known bug 00:43
github.com/moarvm/moarvm/issues # it's here :) 00:44
bbkr MVM_SPESH_DISABLE=1 did not help 00:45
timotimo OK 00:46
spesh_disable also disables jit
JimmyZ thinks it's a GC bug :P
jnthn JimmyZ: Possible, but previous such issues have often not been that 00:48
(GC happens when all threads have agreed "it's a safe time", so there's actually quite a lot less to go wrong during that.) 00:52
timotimo yeah
00:53 raiph joined
JimmyZ perl6 -e 'loop { start { say "hello" } }' # the easy way to get the bug... 00:53
timotimo oh?
we already lock output stuff, don't we?
When invoking , Provided outer frame 0x376a560 (MVMStaticFrame protect) does not match expected static frame type 0x3774f30 (MVMStaticFrame start) 00:54
i get that after a whole lot of hellos
JimmyZ not sure whether it's the same or not, but similar
00:55 xenoterracide_ joined
timotimo i cannot pipe that into wc -l because that doesn't trigger the bug any more ... 00:55
JimmyZ timotimo: you will get different error after some retry
timotimo No such method 'vow' for invocant of type 'Any'
in method start at src/gen/m-CORE.setting:20725
in sub start at src/gen/m-CORE.setting:20774
after 20 wallclock (35.3 user) seconds 00:56
bbkr I also get jvm bugs when using Promises on the same code - gist.github.com/bbkr/4276c813fc518665a457 - maybe clang is to blame?
timotimo hmmm 00:57
huh, interesting 00:58
this time it stopped writing hello
but it's using a whole lot of cpu time 00:59
so ... must be a live lock?
saying an increasing number gets me to 15818 and then "no such method vow" 01:00
JimmyZ another cpu cost: loop { say "hello"; } cost ~20% CPU ,but with perl5 it costs ~1% cpu
01:00 anaeem1 joined
bbkr in my case "No such method 'vow'" on 46029th iteration 01:01
"invalid status -427132408 in GC orchestrate" on 51480th
"Abort trap: 6" on 63050th 01:02
timotimo could become a stresstest i suppose
JimmyZ I meant perl6-m cost ~20PU 01:03
~20% 01:04
timotimo thought so
01:05 anaeem1 left
bbkr "my $x = 0; loop { start { sleep 0.01 } }" always gives me SEGV 01:05
when variable declaration is removed it works fine 01:06
moar: my $x = 0; loop { start { sleep 0.01 } }
japhb If you can turn it into a bounded loop and still get the errors, that's definitely a good stress test. 01:07
How long does it run before failing?
bbkr "loop { start { sleep 0.01 } }" also failed. after 2 minutes on i4770k + 16GB RAM. 01:08
with variable it fails within few seconds
japhb bbkr: The fact that the presence of 'my $x = 0;' is a reliable SEGV switch seems like a strong indicator.
Oh wait, without it its failing too? Dang. 01:09
bbkr yes, but it takes much longer
japhb hmmmm
bbkr ah, that was not true at all also. another try without variable segfaulted within 2 seconds 01:10
looks like SEGV is ceratin but time is not
JimmyZ A good random time producer :P
japhb Sigh 01:11
jnthn If only we had a good random people-capable-of-finding-thread-bugs producer... :P
Well, s/finding/fixing/ I guess :P
japhb At least you can get a reliable SEGV on very short valid code.
jnthn *nod*
Yes, that's an improvement. 01:12
Now I just need some undisturbed, non-exhausted, time to dig into them.
japhb I'm hoping that if we get the failure repro code short enough, then there's only so much in the VM that could actually even get touched. :-)
japhb idly wonders if its possible to reproduce the error with a very restricted setting. 01:13
Can you spawn threads in RESTRICTED?

japhb m: start { say "Hello"; }; sleep 2; 01:14

smls In any case I'm sceptical about the special parsing rules for blocks 08:54
Also the "semicolon optional after a } at the end of the line" rule
In Perl 5 it only applied to block statements like for/if, which are *already* special as far as parsing is concerned 08:55
08:56 rindolf joined
smls In Perl6 it was extended to all blocks, but I don't feel like that increases overall "consistency" -- more like spreads the inconsistency further... ;) 08:56
...into places where innocent writers/readers of code might not expect it.
moritz smls: have you ever used Mojolicious in p5? 08:57
smls no
moritz smls: in the ::Lite version, controllers typically look like get '/url' => sub { ... }; 08:58
smls: and when the sub is 10 or 20 lines long, it is *very* easy to forget that this is an anonymous sub, and must be terminated by }; and not just }
smls mmh 08:59
moritz smls: and of course p5 gives quite obscure errors when you forget it
smls: given that experience, I'm very grateful for that rule
smls: also, I routinely forget to close several-line eval { } blocks with a ;
smls I don't tend to use eval, but I do like to use anonymous subs a lot in Perl 5. I don't have trouble remembering that they are expressions, in context. 09:03
I do agree though, that error messages can get pretty bad in Perl 09:04

Sam______ Hi perl mongers 09:26
I've been a perl programmer since 1997... i love this language... BUT... currently doing it more on PHP and C... wanted to switch to Golang... but find C is best for efficiencies... 09:27
Perl is dying
xiaomiao so it goes
Sam______ My proposition is this... we need to make it faster and compiled. 09:28
xiaomiao Gentoo has been dying since 2004, and now it's even used by Google (ChromeOS) and CoreOS
Sam______ CPAN is a treasure trove. COMPILE and speed it up yo! else... it's like a joke now
xiaomiao it's apparently just dying faster every year until it takes over everything (like perl? ;) )

lizmat Sam______: rakudo perl6 *is* compiled 09:28
not yet faster than Perl5, but there are benchmarks in which rakudo perl6 is faster than perl5 09:29
moritz Sam______: your contributions to make perl 5 and/or perl 6 faster are very welcome
and compiling isn't a magic bullet to making things faster
lizmat Sam______: speeding up simple Perl5 code is what "use v5" and JIT compiling promises to deliver
Sam______ fine fine... what about hhvm equivalent for perl then? 09:30
hhvm is a game changer. we need something like that 09:31
xiaomiao Sam______: using php as an example is kinda ... no! go away!

FROGGS yes 13:32
that are two different things
timotimo oh yes
very much so
one is specifying what stuff to import after the use
FROGGS one is a named param and is part of the longname of the module, the other one is about export tags
timotimo the other specifies what exactly gets used
psch it does make sense, seeing as :: is for package separation and a single : adjunct to the class changes the class itself 13:35

dj_goku who manages testers.perl6.org?
