rt.perl.org/Ticket/Display.html?id=127968 # problem in sleepsort marcusramberg found yesterday 09:15
09:23 vendethiel joined
timotimo another thing to think about is that with ropes we can in theory handle strings that big; adding individual parts together wouldn't result in the whole thing being allocated; just a little record of what got concatenated 09:23
however, if you've added two strings that add up to 2**32, you've got to have two 2**31 big strings :) 09:24
and we do force ropes to become one flattened string when we regex-match against them
09:40 lizmat joined
lizmat timotimo: wouldn't that by itself cause a slowdown in the use of regexes? 09:42
other question: while looking at RT #127968 09:43
synopsebot6 Link: rt.perl.org/rt3//Public/Bug/Displa...?id=127968
lizmat is there a reason why Channel.list is not implemented as an Iterator ???
jnthn: ^^^
timotimo i'm not sure what you mean by that?
"that by itself"? 09:44
lizmat well, Channel.list would return a Seq with an Iterator class in which the pull-one would do an nqp::poll ?
rather than first creating a Supply and then taking a list off of that ?
timotimo sorry, i was refering to the previous topic still 09:45
lizmat timotimo: ah, I meant, creating the concatenated string might be already quite expensive
timotimo oh 09:46
well, at 2**32 characters, yeah
you'll be memcpying 2**32 * 4 bytes together
lizmat if it consisted of many ropes
timotimo that can't be fast :)
lizmat I assume nqp::readallfh already creates a single roped string, right ? 09:47
timotimo it should, yeah 09:48
lizmat ?>/|";.,/[plkm,./ 09:51
(that was some chai tea on my keyboard) 09:52
timotimo uh oh! 09:54
lizmat yeah, probably ok 09:55
if I go up in a puff of smoke, you know what happened :-)
timotimo probably makes the keys a bit sticky :| 09:57
lizmat it was sugarless chai (sweetener only), so not too sticky 10:05
and it was only the lower right corner of my keyboard that got hit
timotimo phew 10:26
dalek kudo/nom: 48cc6b5 | lizmat++ | src/core/Channel.pm:
Preliminary fix for RT #127968

I'm not sure why a Channel would need to create a Supply first to be able to create a .list. So I re-imagined Channel.list to be a Seq with a simple Iterator that is polling the Channel. This causes one Channel spectest to fail, but I feel the test is wrong as it apparently assumes there is a Supply underlying Channel.list. Comments / Patches welcome!

bartolin lizmat: RT #127968 was already reported as RT #127960 (which has a backtrace but no details otherwise). I could merge both tickets (and keep your subject) or I could reject the earlier report as a dup. do you have a preference?

Link: rt.perl.org/rt3//Public/Bug/Displa...?id=127960
timotimo have you looked closely at what the Supply method on Channel does, exactly?
lizmat timotimo: yes, and it is useful in and of itself 10:38
but I'm not sure we need it to create a .list
so you could argue I implemented a work-around yes :-)
bartolin: argh, why didn't I see that in my mail ? 10:39
please merge the two tickets: the stack trace may be useful for someone like jnthn 10:40
bartolin will do

timotimo there is no such PR as a bad PR :)
clearly, the user must have accidentally run into this problem? 11:13
jnthn yeah
Maybe we should just make our string length 64-bit :P
"Overflow *that*!"
tadzik . o O ( I had trouble reproducing this, my SSD was not big enough to put swap there, but... ) 11:29
lizmat I'm confused now: shouldn't .list not return something listy and isn't a Seq a listy thing ? 11:36
jnthn Seq isn't really list-y enough 11:38
Doesn't bind to @ for one. 11:39

proposed patch: gist.github.com/tadzik/2001b1f3ec4...3655b58ab2 16:03
it can theoretically trigger from user error, is someone literally does "die 'Constraint type bla bla'" from their MAIN, but I'd argue that it does more good than harm
spectests pass, so I'm tempted to go ahead with it and ask for forgviness/mercy later 16:19
nine_ Could the .backtrace[0].subname fail somehow? 16:21
tadzik you mean: yield a false positive?
nine_ More like do we always have a backtrace and does the first element always have a .subname?
tadzik ah 16:22
Backtrace::Frame always has a .subname
and I don't think we can have a backtrace with 0 frames in any case 16:23
moritz? 16:26
moritz uhm 16:28
there are filtered views on backtraces
they can certainly be empty

rakudo/nom: Fix EVAL during precompilation
rakudo/nom:
rakudo/nom: EVALed code is considered an independent compilation unit that gets compiled
rakudo/nom: using a new World which contains an independent serialization context. It also
rakudo/nom: gets its own QAST compiler.
rakudo/nom:
rakudo/nom: When a BEGIN time EVAL is run during precompilation of a module, the
rakudo/nom: independent SC would not be written into any file but would still be referenced
rakudo/nom: from the outer compilation unit. We therefor use the outer world's
rakudo/nom: CompilationContext which contains the SC. We also need to share a couple of
rakudo/nom: other attributes that keep track of the compilation's state.

oh, two commits actually; dalek swallowed one
nine_ Well the second one was a quite quick refactor, not even comparable to the work that went into the first :) 16:36
And it may well be that I have to re-visit this topic again as it's only an 80 % fix. It's enough to unblock the repository work though.

dalek kudo/nom: 688ddee | lizmat++ | src/core/Version.pm:
Add Version lt|le|eq|ne|ge|gt Version

It would seem we need a richer set of operators for Version comparisons. This causes some (un-spectested) changes:
   say v2.8 eq v2.8.0; # False before, now True
   say v2.8 eqv v2.8.0; # False before, still False
