moritz is that a feature you actually want/need? 07:53

moritz on second thought, the DWIMming on '-' should probably be off by default, so that the defaults are safe 07:59

sorear although, there is an argument to be made for providing easy access to $*IN from $*ARGFILES 08:30
I suspect that the need for this stuff has been eroded by shell and kernel improvements 08:31

sorear hmm. I've spent some hours trying to design a very compact, random access format for unicode property data, but now I'm starting to wonder if random access is even relevant 09:20
the Perl 5 model is to store property data in a non-random-access format and convert it into swashes on first use

aaaargh, mp_get_int only returns 32 bits, even on 64bit platforms 09:45
and it says so right in the docs 09:46

make nqp::isbig_I consistent with set_int and get_int

turns out that set_int and get_int only support 32bit, even on 64bit platforms. While the better fix would be to make them work on 64 bit width, this approach change nqp::isbig_i to return 1 if the stored int takes more than 32bit.		 13:43

japhb I'll give it a try anyway, I've got a 32-bit box here ... it will just take a while to build. 18:59

moritz no takers yet 19:17
japhb Incoming
Er, supposedly.
tadzik no 32bits here :/
japhb Hmmm. Appears nopaste does not like me today
Ah, could only paste into MAGnet. 19:18
19:18 fsergot left
japhb moritz, the paste should be on #parrot now. 19:18
moritz japhb: thanks. Can you please also change $i to 28 (instead of 30) and paste the first 6 lines of the output then? 19:20
19:27 cooper left
japhb moritz, sorry, got pulled away for a bit 19:27
OK, will do.
19:29 wolfman2000 left
japhb moritz, OK, paste (of full output, sorry, it's easiest) is in #parrot 19:30
moritz japhb: thanks again
japhb moritz, np, hope it helps
moritz japhb: it does. Unfortunately it tells me that my latest patch is broken on 32bit :/ 19:31
japhb Oh dear.
Ah, wait.
May not be your fault.
I built from rakudo, and it pulled nqp. May not have gotten latest. 19:32
Hold on
moritz the 1 is the output from nqp::isbig_I 19:33
which checks if an integer is too large to unbox to a parrot INTVAL 19:34
when it returns 1 even if it shouldn't then it makes the codgen inefficient
when it returns 0 even if it shouldn't then we lose precision 19:35
japhb :-(
japhb is rebuilding NQP
Ughh, I hate building on slow hardware 19:36

diakopter btw, latest parrot regresses on parrot-nqp; after 3.9.0 there was a change that made parrot-nqp generate wrong pir for the *.pm in nqplua/nqpclr 20:09
I didn't bother reporting it to #parrot since all my other bug reports have gone ignored
20:14 ksi joined
benabik diakopter: Wrong how? 20:18
diakopter I got a "could not call method on variable because it's Undef 20:19
"
or something like that
downgrading to 3.6.0 (package in ubuntu) fixed it
benabik Between 3.6 and 3.9, then?
diakopter or after 3.9 20:20
I've used 3.9 on windows and it didn't have the problem
I was using parrot Head
on ubuntu
before downgrading to 3.6.0
benabik So probably 3.9+, but possibly anywhere since 3.6. Fun. 20:21
Where is nqplua?
diakopter diakopter/6model.git
benabik diakopter: I've got a bit of spare time between studying, I'll see what I can track down. 20:22
diakopter I'll see if I can reproduce it with 3.9 on ubuntu
3.9.0 (built from source) didn't have the problem 20:27
sigh. now I can't reproduce it with the same parrot checkout I had the problem with earlier. 20:28
