BenGoldberg Just randomly browsing through some of the perl6 modules, and I came across Compress::Zlib, and noticed an odd logic error. 01:17
Specifically, in class Compress::Zlib::Wrap, method get(), $i is assigned the result of Str.index, then used as an argument to Buf.subbuf, which is only gauranteed to work if the encoding is single-bytes. 01:19

gtodd BenGoldberg: why only then? 02:01
02:02 rindolf joined, Akagi201 joined
BenGoldberg Suppose that the string's encoding is 2 bytes per letter. Then you'd need to multiply $i by two before using it as an index into the Buf for it to be right. 02:03
And if the encoding is unknown, or variable-width....
gtodd oh because a Str index is assigned and then used for the Buf 02:04
BenGoldberg Right. 02:05
gtodd so the index into the Buf would work but ... not always
I wonder if an easy failing test could be written and how easy that would be to fix by just multiplying by bytes per character (i.e. a hack) :-) 02:06
there's probably a more correct way 02:07
BenGoldberg Add a an input-Str buffer to the class, and when reading, append the Str which results from decoding the Buf to the buffer, and discard the Buf; then play with the Str. 02:14
02:17 aborazmeh joined
gtodd I was going to say why does it decode into a Str and not just directly deal with the Buf :) 02:19
but that is just me wondering about Str and Buf

The spec does *not* mention that the first word should be returned instead of the list, if there is only one word found. This causes a problem with << >> interpolation at the moment, which is under investigation.
Also add add :eager / :count parameters. The :eager version is about 10% faster than before. The :count version is about 30% faster than the equivalent (:eager).elems.		 10:46

jnthn FROGGS_: Uhm. On what benchmark, exactly?
FROGGS_ jnthn: as user came and reported a regression in his code (about five times slower) 13:27
jnthn Well, lemme do some measurements here.
FROGGS_ then it got golfed down... in the end it was just a loop and a push to an array with one element
that was our "microbenchmark"
jnthn OK, well, something is wrong then 13:29
Because
FROGGS_ see irclog.perlgeek.de/perl6/2014-08-28#i_9260375
jnthn I just reverted the commit TimToady made, and
perl6-m -e "my @a; my $i = 0; while (++$i <= 1000000) { push @a, 1 }"
Before revert: 27.309s
After revert: 7.509s 13:30
So it looks to me - and to timotimo's benchmark runs - that the "pessimization" wasn't so pessimal after all in some cases. :)

value.gimme(*) if nqp::istype(value, List); # fixes #121994
synopsebot Link: rt.perl.org/rt3//Public/Bug/Displa...?id=121994
jnthn That has gotta be a hack...but it also means that the split iteration is run in that case
Whereas in the other caes it's not
And I bet that's where the extra cost comes from.

jnthn I now have a patch that seems to not re-introduce #121994, gets the perl6-bench one in 6.793s (better than before the revert and WAY better than now) and actually gets the case TimToady pulled out the sinlge candidate case for faster too (2.727s, dwon from 3.320s). 13:48
So providd this spectests OK, we get wins on both benchmarks over their previous bests.

TimToady so, in perl6-bench, after I did a fetch, I didn't expect a build to rebuild the entire world, including the all the "stable" old versions of everything; how can I just rebuild the things that changed? 16:42
16:43 raiph left
TimToady japhb: ^^ 16:44
or do I have to cd down and do such builds by hand? 16:45
16:45 Akagi201 left, johnreed left
TimToady it's doubly irritating because all the old builds take twice as long... 16:45
16:48 raiph joined
gtodd maybe it will only do that once? 16:49
TimToady and all I want to do is to see if my new test of push @a, @a comes out scaled correctly
I already did it once last night
now it's doing it again
gtodd that seems .... suboptimal for a large set of situations 16:50
TimToady of course, when it's not busy overheating my lap, it's sitting there trying to update submodules on old version, which presumably are tagged anyway
anywya, it seems that 'bench build' reconfigs everything, which is no fun at all 16:51

lizmat FWIW, after jnthn's latest pull, the spectest seems a little slower to me (and more CPU, 1200+ for the first time in a long time) 17:23
TimToady my informal run of bench last night had current (as of yesterday) rakudo decreasing to 3.3% of P5, with a peak of 4% on 2014-08 17:27
so that tends to confirm that things have got slower 17:28
TimToady also provides a grain of salt with that

TimToady dunno how much of that is just the "push" effect 17:29

TimToady timotimo: I made the mistake of typing 'bench build' this morning, and am still awaiting the results; do you have any secrets for building just latest without rebuilding everything? 18:27

actually
gtodd so is it the moar backend's slurpy_positional doing that?
lizmat no idea: 19:23
$ time perl6 -e 'my @w := slurp.words; .say for @w.Bag.pairs.sort({$^b.value cmp $^a.value})[^10]' <text2 # works for me and takes ~ 5.5 seconds

lizmat $ time perl6 -e 'my @w := slurp.words; .say for @w.Bag.pairs.sort(*.value).reverse[^10]' <text2 # this version takes 6.5 seconds
gtodd heh yeah it's faster to count words than to match words in a logfile ... anyway just wondered if it was effecting anyone else ... my p6-p and p6-j work - only perl6-m crashes 19:27

someone smarter than me must poinder why masak's elegant code doesn't work ... :-) I can't really say when it started 19:32

lizmat gtodd: seems the segfault doesn't happen if the file is truncated to the first 5655 lines 19:46
if it has 5656 lines, it segfaults
gtodd yesh .. for me it was 5654 lines and then a few more chars
TimToady you can't implicitly hyper a - like that 19:47
gtodd !!
lizmat TimToady: do we have another way to say "the last 10 elements" ? 19:48
TimToady [ *-10 .. * ] maybe
lizmat gtodd: 5654 lines, indeed 19:49
TimToady [ * X- ^10 ] maybe
[ * «-« ^10 ] maybe
19:49 Psyche^_ left
TimToady but you can't automatically assume a - will distribute over a range 19:49
lizmat [*-10 .. *] works 19:50
TimToady or course the X and hyper, if they work, will be in reverse order
lizmat ah, yes, reverse order... hmmm.. 19:51
TimToady and * - 0 will be off the end in any case
gtodd in vim it's 10$ :-)

lizmat gtodd: did you rakudobug it already ?
gtodd no ... wondered if I should file it under moar repo on github or on rt.perl.org ... 19:55
lizmat rakudobug for now, with the indication that it's a moar specific rakudo problem
gtodd ok so just mail it to [email@hidden.address] and it's all good or ...? 19:56
lizmat yup

bartolin while building perl6-p on different BSD systems I repeatedly stumbled over dyncall. AFAIK dyncall is an external library included in nqp. for FreeBSD (10.0), OpenBSD (5.5) and DragonFly BSD (3.8.2) I had to add -fPIC as a compiler flag for building dyncall. for OpenBSD (5.5) this was not necessary, since Position Independent Code is enabled per default. (I googled that one :-) 20:26
since I'm not familiar with dyncall: do you think I should report this issues upstream (to the dyncall developers)? I'm not sure I'm able to describe the problem properly. I *think* we run into trou
20:26 virtualsue left
bartolin ble because we build shared libraries of dyncall which we use later in our build process. 20:26
erm 20:27
20:28 cxreg2 is now known as cxreg
timotimo oh btw 20:29
is rakudo vulnerable to that real number that causes double parsers to loop infinitely?
gtodd bartolin: I might be wrong but did Chohag find different versions of dyncall being used in nqp parrot etc. ? 20:30
oh wait ChoHag is here :-)
PerlJam timotimo: sounds like a good test to write anyway, just in case :)
ChoHag Sort of here.
gtodd anyway bartolin++ for chasing this down ... I got perl6-p to build (finally) but it is very slow and the repl is strange (I need to press return twice to get into it or exec lines of code?) ... rebuilding on some more machines again now :) 20:32

gtodd bartolin: do you have hardware or vm's for your BSDs ? ... if they are bare vm's can you share ;-) 20:33
bartolin gtodd: I installed some KVM guests. At the moment they are definitely not ready for sharing :-/ 20:34
gtodd: But sounds like a nice idea.
gtodd heh ok I have some VBox VMs ... contemplating 11-CURRENT and bhyve :-) 20:35

bartolin gtodd: regarding dyncall: I found only dyncall v0.8 included at github.com/perl6/nqp/tree/master/3...ty/dyncall 20:35
20:36 [Sno] left, [Sno]_ is now known as [Sno]
gtodd I think I will "down tools" and update netbsd and openbsd and various 9 and 10 series VMs before trying any more weekly builds 20:36
bartolin: ok I must have mis-remembered that discrepancy 20:37
bartolin gtodd: And adding -fPIC as a compiler flag enabled me to build perl6-p for different BSD variants (as above).

bartolin gtodd: I saw yesterday, that upstream added -fPIC for FreeBSD as well: dyncall.org/svn/dyncall/trunk/dyncall/ChangeLog 20:38
gtodd bartolin: ye nice I grabbed head/master with --gen-parrot=master
bartolin gtodd: But only in trunk (yet) and not for NetBSD or DragonFly BSD
gtodd since I'm bleeding edge for parrot that might explain other slowness ... is the patch now in the parrot 6.8.0 release ? 20:39
oh only trunk
ok
bartolin gtodd: It's not in parrot 6.8.0. IIRC rurban++ said, it should probably go in 6.8.1 20:40
gtodd I shouldn't think of parrot as upstream but it is kind of upstream to rakudo ;-) dyncall is double upstream :) 20:42
bartolin Well, for the moment I'll patch nqp's version of dyncall, so that perl6-p is buildable on DragonFly BSD
gtodd have not used DFly for some time ... needed hardware to do so back then
bartolin gtodd: then I was referring to double upstream ;-) 20:43
gtodd will DFly run in a kvm?
bartolin I just installed it
But did not a lot more than building parrot and perl6-p ;-) 20:44
tony-o timotimo: i don't know if you've pulled http-server-async recently but i have the tests messed up 20:45
