labster Though I wrote that, I'm starting to wonder if functions like dir(), unlink(), etc should actually throw their errors, or just fail instead. 00:37
00:37 mrallen1 joined
labster And let sink context cause it to throw in most cases. 00:38
flussence fail makes more sense IMO; if you write something like @tmpfiles».unlink you wouldn't particularly care if one's gone missing in the meantime. 00:40
timotimo_ (also it wouldn't give you a way to figure out which ones were unlinked and which weren't up until the failure 00:41
flussence that's what .map is for :)
timotimo_ sink-failing makes more sense imo 00:42
labster those are good cases 00:46
00:46 aindilis left
labster so I'll probably go ahead and change it 00:46
Though it's hard to write. "if it fails, it returns an X::IO::Unlink failure" sounds circular. 00:47
flussence "the failure will be of type X::IO::Unlink"? 00:48
timotimo_ its inner exception will 00:49

In C++, for instance, a future is a container-ish-thing, which you get the value from like joining a thread, and the default implementation is done with a thread pool.

sorear there is some stuff there which might want to become permanently part of the docs
07:15 rurban left
diakopter sorear: for re-enterable frames, will each routine's entry point check for re-enter mode by a parameter? or is there a special version of each re-enterable routine so the check isn't necessary 07:19
07:20 raiph left
sorear diakopter: check by parameter 07:21
diakopter sorear: what are better names for the unfortunate 3 names? :) 07:23
(srsly)
sorear "unfortunate" mostly applies to "shift" 07:24
which is the last thing you should call a control-flow operator in Perl, but the name is standard and used in real-ish languages like Racket 07:25
diakopter heh. :)
sorear we can probably get away with "reset"; the perl 5 function of the same name is mercifully almost forgotten 07:26
trivia: in an earlier draft of that document I had shift and reset swapped everywhere. that's how mnemonic the standard names are.
diakopter might as well randomly generate names for these.. they'd be just as memorable/meaningful
07:27 ponbiki joined
diakopter nqp::BNCOWKEJT nqp::ZXMNCBVWETUBV and nqp::WEUBVKUXCTWEYXZZA 07:27
:D
sorear I'd rather randomly pick from the ten hundred most often used words in English 07:28
diakopter seriously though, I'm trying to piece together how these would be implemented in moar..
sorear reset drops a cookie on the stack. shift memcpys off all the stack up to the cookie. 07:29
diakopter what if a closure is generated "deep" then its stack is swapped out, then the closure is executed and it tries to bind stuff "upvalues"
07:29 FROGGS left
diakopter *to 07:30
sorear we don't touch the actual callframe objects 07:31
we just rearrange the pointers to them on the VM stack
the closure holds direct refereces to the frames with upvalues, so it doesn't even see the pointer shuffling
diakopter one suggestion: s/cont/dc/ in the opnames 07:32
nwc10 but implicit to all this working is that callframes are (heap) allocated, and not stored directly on the stack?
diakopter the Java stack, yes. also, yes, the moar stack too
nwc10 that seems to be an unstated assumption 07:33
diakopter for lexicals anyway
sorear nwc10: the parts of callframes that need to be referenced by closures, yes
if nothing gets closed over on a given callframe then it can probably be put on the VM stack 07:34
diakopter locals can be frozen/sublimated O_O
sorear does his best ambivalent larry impersonation
nwc10 sorear: yes, I was just thinking this. More (and this is an optimisation, and right now it's premature)
diakopter sorear: it's working :P
nwc10 the GC has forwarding pointers - right? So, store the things on the stack initially. But if a closure is taken, move them off the stack into allocated structures, and have the things on the stack turn into forwarding pointers 07:35
but, I repeat, this is a conjectural optimisation
sorear diakopter: you think s/cont/dc/ would be an improvement? I started with dc but thought "nah, nobody will guess what dc stands for"
nwc10 Or they'll all object, because the prefer Tesla to Edison? :-) 07:36
diakopter cont is too ambiguous, but dc is cryptic/distinct enough that it names a new thing, imho
sorear nwc10: I'm skeptical. We know at compile time whether a given sub has children that *could* close over it, and my intuition says that if the user bothered to write a nested function, it will almost certainly get used
nwc10 sorear: OK. 07:37
diakopter nwc10: JVM GC? no.. but Moar GC.. sort of, but not like that
sorear diakopter: (cont/dc) hmm. I think I see where you're going here. 07:38
diakopter delcon :D
dlmtdcntntn
sorear that can be jnthn's next branch name 07:39
diakopter nwc10: I suspect it wouldn't be an optimization to use the cpu stack for such things in moar, unless it's *heavily* optimized, native types only, ultra simple control flow, easily-jitted code 07:40
however, I could be *totally* wrong there, given actual experimentation instead of just thought 07:41
sorear using "the cpu stack" for much of anything in a continuation/coroutine/green thread oriented VM is not going to work very well 07:42
for a variety of issues, including:
* poor LLVM support for GC mark data for the CPU stack
* poor Windows kernel support for stack switching
nwc10 yes, also like Perl 5, moar is "stackless" isn't it? In that language level subroutine calls don't recurse at the C level?
sorear * gymnastics required for sigaltstacking 07:43
diakopter nwc10: yes
nwc10 yes. OK. So the language-level "stack" involved is going to be a MoarVM managed thing anyway
sorear etc
nwc10 shuts up and goes back to the Perl 5 code mines :-)
diakopter nwc10: wait :)
nwc10 wait?
I've still got the window open
07:43 sqirrel joined
diakopter heh, one sec, a further question 07:44
re: stackless...
sorear standard-ish practice (used by GHC, for instance) is to set aside a block of memory and treat it like a CPU stack, but explicitly and not using %rsp
GHC-generated code is stackless on the C-stack. when compiling using LLVM, every call is a tail call
nwc10 sorear: yes, I was wondering *that*. Perl 5 does something like that
sorear GHC uses StackTop, StackEnd, HeapTop, HeapEnd registers, which leaves x86 quite cramped :) 07:45
diakopter nwc10: I was planning to use B::Hooks::XSUB::CallAsOp‎ to "invoke" p5 code from xsubs on moar's p5 thread, to keep recursively-cross-VM callbacks stackless on both sides... sound sane?
sorear perl 6 probably does not need to optimize memory allocation to *quite* that extent
nwc10 in which case, it's a trade off about stuffing call frames on that versus explict allocation. And I'll totally agree that the right thing to do *now* is roughly "simplest thing that could possibly work", and worry about optimisations once we have real-world data
I don't know what B::HOoks::XSUB::CallAsOp does 07:46
diakopter nwc10: also, rafl volunteered to make that module re-entrant (it's not at the moment)
basically makes an optree node for an xsub invocation 07:47
07:47 FROGGS joined
diakopter [and what the xsub invokes] 07:47
sorear o/ sqirrel, FROGGS
nwc10 diakopter: I can't find any terse explanation for what that code does 07:48
07:48 Tsuki-san joined 07:49 raiph joined
nwc10 but if I'm guessing right, it seems like it's a way to go 07:49
diakopter it creates a temporary trampoline in the current spot of the p5 op tree that can hold your current xsub invocation
07:49 Tsuki-san left
nwc10 and then returns from the XSUB back out to the runloop? 07:49
diakopter yes
nwc10 and at the end of the invoked OP (or OPs), re-enters XS and the XS can exit like nothing special happened?
diakopter yes
but currently it supports only 1 descent per thread 07:50
nwc10 approach seems sane. It's what I thought about a few nights ago
I don't want to comment on the implementation :-)
diakopter :D
07:51 wbill left
sqirrel o/ sorear 07:51
diakopter can't do anything about recursive cross-VM calls that already create their own nested runloops
that's their own problem ;) 07:52
FROGGS hi sorear
diakopter sorear: implementing your spec in moar would be .. straightforward enough.... however, I think jnthn may grouse about it obviating a lot of optimization potential 07:53
unless it's blocked more strongly from non-compiler access
sorear diakopter: it's totally reasonable to restrict portions of it per HLL, or even implement something different 07:54
this spec looks the way it does because 1. it's a well studied API 2. it's a close match to the actual functionality of the JVM stack freezer/thawer 07:55
nwc10 wonders when jnthn will wake up
sorear 2 does not apply to moarvm
diakopter true, I forgot your nqp::xxxx don't actually need to be nqp::xxxx in moar... just moar opcodes 07:56
sorear it would be entirely reasonable for moarvm to implement, say, a "green threads" abstraction instead
gather/take can be implemented on top of green threads as well as it can on delimited continuations 07:57
not all nqp:: ops are available on all backends
the ops I'm designing should be interpreted as "JVM only" until such time as some other backend wants to support them 07:58
diakopter sorear: I have a sneaking suspicion that 1 coordinated extra thread/eventloop per gather descent would be more efficient than the jvmstack/callstack swapping... but I'll wait until you're done to even try to attempt an alternative implementation ;) 07:59
sorear diakopter: I look forward to the comparative benchmarks. 08:00
08:00 brrt left
diakopter the rationale of this truly gut-level suspicion is my sky-high levels of trust/awe in the JVM concurrency efficiency 08:01

if you build up a list of keys to delete 13:50

you usually want to delete no keys, not all

moritz then I retract my objection 13:53

[Coke] I just said it out loud a dozen times, sounded like equal stress. 14:30

14:38 BenGoldberg joined
[Coke] tl;dr - say it however you like. at worst, people will think you have an adorable accent. 14:38
masak wow, people really are divided on it.
while we're on the topic: "gist" -- soft g or hard g? :) 14:39
masak votes hard g
jnthn hard, same as git :)
masak I'm talking exclusively about the pastebin-y thing, if that helps.
timotimo_ i say "djist"
masak that would be a soft g. 14:40
diakopter it's soft...
geekosaur I pronounce with soft g because that's how the English word is pronounced
brrt hard g
brrt is unsure what english-people mean by 'hard g'
diakopter that
btyler soft, same reason as geekosaur
brrt and 'soft g
'
geekosaur also, fwiw, the Mac dictionary agrees with me that American English stresses the first syllable of "intricacies"
diakopter brrt: "get" 14:41
(hard)
brrt ok
diakopter soft: giraffe
geekosaur but again I will repeat that Commonwealth English is likely to differ
brrt i see
in dutch a 'hard' g is really a hard one
like in 'scheveningen' (the first one)
diakopter gist is... soft always 14:42
I was surprised to hear someone say ghist
at yapc austin
brrt hmm
maybe soft gist is acceptable as well
masak diakopter: that was me, in the car to the airport ;)
jnthn diakopter: I say it just the same way as masak, fwiw :) 14:43
[Coke] I pronounce gist.github.com with a hard g, but "the gist of it" with a soft g.
brrt the github site threw me off
colomon gist is a word, pronounced with a soft g, right? like jist
masak diakopter: I guess it really depends if you came at the word thinking "oh, it's that word from English", or thinking "oh, it's a derivation of 'git'"
brrt natural 'british' would be soft
jnthn Right, I would use a soft g for the English word "gist"
geekosaur thinks that gist.github is a pun that only works in print
diakopter [Coke]: but gist.github.com is.... the direct meaning of the english "gist"
I didn't think it was a pun 14:44
masak diakopter: how can you be sure?
jnthn Oh, I saw it as a cute pun :)
geekosaur sure it is, it's mixing gist with gi(s)t
[Coke] diakopter: I'm not trying to rationalize anything, just telling you what my brain is doing.
brrt in the context of Git it is natural to say gist with a hard G
geekosaur but the differing pronunciations throw it off in speech; it only works in writing
diakopter well, I should note that I've heard people pronounce the non-github gist with a hard g, too 14:45
same person who insists that the phrase is "get your goat", fwiw
colomon diakopter: yeah, me too.
[Coke] diakopter: get your goat as opposed to? 14:46
geekosaur gist is soft g, per dictionary and derivation (Latin via French, original 'jacere')
(or 'iacere' if you go with classical Latin...( 14:47
masak diakopter: as opposed to "jet your goat"? :P
diakopter masak: you're a joat
geekosaur :p
colomon diakopter: idioms.thefreedictionary.com/goat 14:48
diakopter sigh. it's goad
colomon diakopter: based on what?
diakopter the meaning of the word
colomon diakopter: that's a very dangerous thing to rely on in English 14:49
[Coke] I have never ever ever heard "get your goad"
geekosaur diakopter, if yiu go by meaning, it would be "be a goad" not "get your goad"
diakopter it's in literature
[Coke] ... until a few lines ago, of course. :)
colomon diakopter: so is get your goat

PerlJam masak: "...but nothing else [currently] derives from it" 20:35
lue My question is, what is "it" referring to? It could just as easily refer to C<Any>, which changes that part of the sentence from redundant to wrong (the use of the word "but" especially suggests this to me).

masak PerlJam: again, that seems wholly uninteresting to point out.

dalek ecs: e33d6c9 | masak++ | S02-bits.pod:
[S02] remove useless information about Whatever

The synopsis pointed out that Whatever derives from Any (which is true), and that nothing derives from Whatever (which is true).
If nothing derives from Whatever, does that mean nothing *can* derive from Whatever? RT #105004 determined that it doesn't.
Then what does it mean? Only that before someone writes a class that derives from Whatever, no class derives from Whatever. While, true, that's not a very exciting statement, and possibly misleading. Removing.		 20:42

perl t/harness --fudge --keep-exit-code --icu=1 --tests-from-file=t/spectest.data
and now it just seems to be sitting there.
My computer's fan isn't running, so I'm thinking it's not running any tests.
Ideas?
flussence strace it?
FROGGS top? ps ax? taskmanager?
colomon top is showing three perl scripts in positions #4, 5, and 6. 21:48
and control-C on the alleged spectest run makes them go away. 21:49
labster identical thing is happening here 21:55
did something change in the spectests recently? 21:59

jnthn Quantified quantified things can lead to such situations. 22:13
flussence seen on www.reddit.com/r/coding/comments/1g2fw3/
jnthn has a similar example and graph of timings in his C# course
flussence the good news is rakudo's using a fairly constant and small amount of RAM running it locally :) 22:14

labster colomon: does that mean you can get 'make spectest' to run now? 23:00
colomon labster: nope, I just started running the set tests by hand to see if they might be the culprits
I don't even start to understand how a hang in one test could cause make spectest to not return any output. 23:01
maybe it's a fudgeandrun problem? 23:02
if I try to prove the .t file directly without fudgeandrun, it gets through 40 tests.
jnthn sleep...hope I will be much more productive tomorrow... 23:03

lizmat is "enjoying" another change of itinerary: going from Newark to Amsterdam via Oslo 23:09

sorear lizmat: gonna say hi to arnsholt while there? :) 23:10
lizmat well, I hope that we won't have time to go out of the airport 23:13
we just missed our plane *again* by 10 minutes
our previous flight had delays, but in principle we could still make it 23:14
but at the gate, it took 15 minutes for someone to arrive to get the jetway in place, so we could get out of the plane 23:15
grrrr

sorear where are you now? newark? 23:25
never having had to deal with anything like this, I have one question: is it also turning into a huge money sink? I assume you have to pay for the two empty chairs that you've flown across the Atlantic? 23:26
census good night masak!
lizmat Newark Liberty
sorear: no, we didn't have to pay anything extra.
census vacation in u.s. after yapc?
lizmat but since we want extra legroom, you can pay for "Economy Plus" with United 23:27
sorear census: not intentionally. lizmat & woolfy are just having WONDERFUL LUCK getting back home
lizmat *that* I had to do again, or run the risk of not being able to upgrade
sorear: except of course an extra hotel night 23:28
sorear s/two empty chairs/four empty chairs/
lizmat yup
sorear momentarily forget about woolfy
pmichaud has spent many hours at newark liberty 23:29
lizmat hehe.. woolfy did a good job holding me back when I exploded after having run through most of Newark Liberty to make it to the gate at the farthest end
only to be told we were too late
