Xliff I don't want the role to override A.a 00:49
But I do want A.a to refer to AA.a

Xliff Let's say that C.new.a is running A.a -- how would I refer to AA.a via self? 00:53

Xliff Looks like Inline::Perl5 is broken on latest KUbuntu 10:19
Wants libperl.so.5.30 but current is on libperl.so.5.32
And 5.30 is no longer available.
dakkar does kubuntu ship a inline-perl5 package? 10:21
moritz did you upgrade your OS after installing Inline::Perl5?
moon-child Xliff: recompile?
moritz you might need to recompile Inline::Perl5
dakkar (we're all thinkig the same exact thing 😉)
10:27 sono left
Xliff I did 'zef install --force-install Inline::Perl5' and that didn't change anything. 10:30
And I did that before mentioning anything here... ;)
dakkar ok, you're an advanced user ☺ 10:33
that's very surprising, though
next step: check that you don't have two copies installed 10:34
Xliff Hah! Yep.
Er. Nope. 10:35
0.52 is getting installed, but 0.53 is available
I install from zef, and it says its installing 0.53 10:36
I do info, but it says 0.52 is installed.
dakkar yep, two copies in two different directories
Xliff Hrm. How can I find? 10:37
dakkar `raku -V |grep repo::chain`
should tell you where raku looks for modules
Xliff Well, it looks like I do without :from<Perl5> for now. 10:40
That doesn't help me at all. The names are all hashed.
dakkar yes, the names are, sure
but I'm pretty sure we can figure it out 10:41
what directories does that command show you?
Xliff repo::chain=inst#/home/cbwood/.raku inst#/home/cbwood/Projects/rakudobrew/versions/moar-blead/install/share/perl6/site inst#/home/cbwood/Projects/rakudobrew/versions/moar-blead/install/share/perl6/vendor inst#/home/cbwood/Projects/rakudobrew/versions/moar-blead/install/share/perl6/core ap# nqp# perl5#
dakkar good, nothing too weird there 10:42
`zef list --installed` should `Inline::Perl5` twice for you 10:43
Xliff ....aaaaand....
The package came with a version of libp5helper.so precompiled
Which wanted the wrong version of perl.
dakkar ooh 10:44
Xliff Removed it and rebuilt and problem looks sorted.
dakkar I'm glad you fixed it!
Xliff Believe it or not, you did help a lot! Thanks. 10:56

m6locks hmm I get an error with that
it says expecting any of: generic role 15:16
dakkar works here on 2021.02 (yes, I'll upgrade some day…)
m6locks I have 2021.03 15:17
dakkar where does your rakudo say the error is?
m6locks after the a
ugexe works on blead and on 2018.01
m6locks in class a
ran it again and now it seems to work
dakkar which probably means you had some previous declaration that changed the meaning of that code 15:18
m6locks aye

melezhik i post some r3 tags stat, also including upcoming release if someone is interested - gist.github.com/melezhik/d214191ec...2ce3d50057 16:35
so before release is cut one call always run `tomty --only=rc_2021_07+open` to run tests against all open issues and see if they are pass .. 16:37
or just `tomty --only=rc_2021_07+open --tags` to see tags stat 16:38
that's the idea ...

perlbot nirnam pasted a new file at l.perl.bot/p/x95xhe - 17:39
nirnam I did some fiddleing with experimental.rakumod to make cached worked with hyper 17:40
and I finally did the brenchmark
17:41 poseidon joined, poseidon left
nirnam it gonna carsh every time thread accessing the same cache not just modifying, so I just lock everything that have to do with cache in there 17:43
[Coke] did MasterDuke's try not work? 17:56
nirnam it blowing up on %cache.EXISTS-KEY , he only lock %caches{$key} := target(|c) 17:57
[Coke] interesting. I think he and I both thought we just needed to worry about the *set*, not the get.
I wonder if we have any benchmarks on cached we could test a new impl. again 17:58
17:59 eseyman joined 18:00 eseyman left 18:02 reportable6 left 18:03 reportable6 joined, eseyman joined
nirnam perfomance wise, if I reverse the list before feeding it, hyper with chache is already beating just chache 18:06
not by alot, but it become apparent for very very last set of input 18:07
18:20 RandalSchwartz left 19:20 evalable6 left, linkable6 left 19:21 linkable6 joined
MasterDuke nirnam: so you modified my patch to protect the whole sub? 19:21
nirnam yeah 19:22
19:23 evalable6 joined
MasterDuke did that ever fail for you? 19:23
nirnam Didn't yet, I tried variation of the collatz function, and nothing been blowing up yet 19:24
MasterDuke have you benchmarked cached, but no hyper with the patch and without? i.e., how much does adding the lock.protect slow things down in the case where it isn't needed? 19:25
because if it's not terrible, might be worth submitting as a PR for rakudo 19:26
nirnam I didn't does anything with hyper, and hyper with cached will not work without the patch 19:27
MasterDuke well, i'd say it's worth submitting as a PR regardless, and there is a large performance drop for the non-hyper case that'd be a good cause for discussion
*if there is
nirnam Ah, in that case I should benchmark only cached without hyper, with and without patch on 19:28
19:29 Doc_Holliwood joined
MasterDuke yeah 19:30
19:40 rassoc joined 19:56 melezhik left
perlbot nirnam pasted a new file at l.perl.bot/p/16zsu2 - 19:56
nirnam it does run slower with the patch
when it get to one million there's about 1 minute difference 19:57
I also used 3 lock in there, one for each time %cache is being access in your original patch 19:58
rassoc interesting how much slower cached vs manual memoization via state var is; almost 3x 19:59
20:01 sono joined
nirnam I don't know if I did the manual cache right, but it about the same to me 20:02
rassoc gimme a sec, will create a gist
nirnam I can see small difference, in small input set, I can see how that could scale when there's more and more input 20:04
woo, you're right, it is about 3 times faster 20:06
rassoc gist.github.com/rassoc/7cc2d9b853f...98e9da3ab9
just the non-hyper variants
and there's a huge gap to ruby :( 20:07
nirnam and astronomical gap to C, but we don't talk about C 20:08
I tried it in C, it took .5 second for one million chain
rassoc yeah, same deal in crystal; virtually the same ruby code

rassoc sbcl? can't reproduce, way slower for me 22:05

rassoc sure, and this is ruby with 1mil: 2.11 s, 169560 kb 22:10
not THAT bad
22:10 littlebenlittle[ joined
rassoc raku is still crunching ;) 22:10
moon-child heh, that one took me 1-2 minutes 22:11
rassoc typing didn't help at all. was curious whether uint annotations would help, but those aren't implemented for hashes just yet 22:12
22:22 Doc_Holliwood joined
moon-child I would try using a buf32 instead of a hash, and just falling back if it's out of range 22:29
rassoc try it, hehe. raku did swap like crazy for me :) 22:33
moon-child oh it'll autoexpand
rassoc yeah, max key is 1570824736 for 100k 22:34
japhb Commented with a micro-opt 22:39
22:39 cognominal left
japhb BTW, gist.github.com/rassoc/7cc2d9b853f...l-raku-L12 forces constant type coersions from Num to Int. 22:40
(Because 1E5 is a Num, not an Int) 22:41
22:41 cognominal joined
rassoc initial solution isn't mine 22:42
seeing 2.19 s, 154772 kb for yours; slick
that's ruby's runtime for a 1mil seq 22:43
japhb Err, wasn't claiming it was, just explaining for those who wondered why that variant was so slow.
rassoc 1.7s even; system had load 22:44
welcome to the club of crappy i3 machines ;)
