Ven_ how hard would be `is parsed` to implement ? (and at what cost ?) 08:04
moritz nobody has done it before; it'd need exploring 08:06
(and you'd need to be able to build rakudo for it :-)
the cost? time, partial sanity downgrads
masak it's at least an interesting challenge.
with mutating the actual parsed program colliding a bit with changing immutable cursors. 08:07
or something.
Ven_ I can build rakudo, but only on my debian vm :)
masak jnthn++ claimed to have seen a way forward once.
Ven_ cost, as in "how badly would it hurt the perf" 08:08
masak should be a no-cost thing for those who don't use it.
08:15 zakharyas left
moritz aye 08:16
masak: fwiw I can kinda also imagine a way around the immutable string+cursor problem
08:17 cognominal__ joined
masak excellent. 08:17
moritz basically, parsing the returned string with a fresh cursor, and then creating a dummy cursor from begin to end of the 'is parsed' string
but it'd mean you can't return '} else {' and have it magically inserted and work
08:18 ggoebel111113 joined
moritz not sure if that's a bug or a feature :-) 08:18
08:18 zakharyas joined
masak hm, why would it mean that? I don't see the connection. 08:18
oh, because of nested braces and stuff?
moritz yes, because stuff that's returned would have to be parsable on its own 08:19
by some subrule or another
masak 'fraid that's too restrictive.
moritz maybe 08:20

masak about Python's indentation: 08:55
FROGGS yeah?
(I'm sorry)
masak on the beginner course I gave this week, I received the question: "how do I solve merge conflicts involving indented Python code?"
FROGGS heh 08:56
masak as I pondered the answer to that question, I realized that the redundancy provided by curly braces simply isn't there in Python.
and so resolving merge conflicts is understanding-complete.
whereas in braced code, you can often mark the region, hit the "justify" button, and you're done.
08:57 lue left, atroxaper joined

.oO( brace yourself for merging! )

lizmat good *, #perl6 09:09
a new morning, new commits, a faster spectest again, it's a good start :-)
time to write some more tests to make the spectests take longer again :-) 09:10
jnthn needs a challenge :-)
09:10 lue joined
jnthn aarrghh :P 09:11
We really need to reduce the amount of "sleep" in the concurrency tests.
Like, by writing a TestScheduler or something
09:11 frettled_ is now known as frettled
jnthn So we can virtualize time there. 09:11
lizmat are you worried about the latency ?
personally, I'm not so worried, but then I have TEST_JOBS=8 09:12
jnthn I'm worried about the fact that spectest used to be < 300s for me, now it's 400s, and it's got no slower ahead of S17 afaict.
I can TEST_JOBS=8 it, but on Windows it sets them off in batches of 8.
lizmat runs a spectest without S17 tests
jnthn And all 8 have to be done before it'll set off the next batch.
So tests that sleep clog the entire pipeline for me. 09:13
lizmat ah, ok :-(
jnthn scheduler.t is probably the worst culprit, fwiw.
I'm not going to complain too much 'cus I'm happy we have tests. :) 09:14
lizmat so making many smaller S17 test files is not advantageous for you at all
jnthn It is
Because each one gets done quicker
lizmat ok, *phew*
jnthn And so it can set off another batch of 8.
lizmat wonders why testing on Windows needs to work that way 09:15
moritz probably has to do with no fork() available
lizmat ah, of course :-(
jnthn
.oO( forking hell... )
moritz iirc the first versions of those TAP:: modules didn't support parallel testing on widnows at all 09:16
masak +1 on TestScheduler
moritz (the first ones that supported parallel testing on *NIX, that is)
lizmat with S17: Files=834, Tests=31812, 200 wallclock secs ( 7.88 usr 3.73 sys + 1258.84 cusr 139.42 csys = 1409.87 CPU) 09:17
without S17: Files=808, Tests=31152, 180 wallclock secs ( 7.65 usr 3.64 sys + 1203.90 cusr 97.87 csys = 1313.06 CPU)
moritz 20s difference 09:18
lizmat 2% of # tests, 7% of used CPU, 10% of wallclock 09:19
nwc10 the test scheduler is Perl 5?
lizmat yes 09:20
basic prove functionality afaik
nwc10 yes, bulk88 has a patch
the basic problem is that Microsoft are utter fuckmuppets and didn't implement sockets correctly
Win32 sockets *drop* unwritten data on the floor if the process exits
moritz and bulk88+ was heroic enough to patch windows sockets? :-) 09:21
nwc10 result - you can't take a default Windows command line program, and run it with output sent to a socketpair, and expect it to work
and sockets *are* select-able on win32
lizmat so what would we need to use this patch ?
nwc10 but pipes (which don't have the fuckwittedness) are not
jnthn oh joy...
nwc10 you'd need someone to review it, and if valid commit it to the TAP::Parser repository 09:22
or implement an alternative
the obvious (hacky, but works, and already implemented elsewhere) trick is you put an intermediate process (or thread)
which has a pipe from the child
and pumps it down a socketpair to the test harness
moritz t/spec/S05-mass/properties-general.rakudo.jvm ................ No subtests run
is that expected?
nwc10 and as it *knows* that its output is a socketpair, it can do the proper shutdown dance
I am really not impressed by Microsoft on this one. They've taken a well designed BSD feature, and failed to implement one of the key parts of it 09:23
which is strange, because they do take actual BSD code and use it 09:24
as evidenced by the fact that WinCE had bugs with classless internet domains (and IPs that used to have to be network addresses)
when CIDR pre-dates WinCE by a year or two
IIRC it was parcelfarce.linux.org.uk - for a while it had an IP address that was one that could not have been a host address before CIDR 09:25
and WinNT machines couldn't connect to it 09:26
(that might have been seen as a feature)
Windows 2000 fixed this, IIRC

FROGGS jnthn: the STable thing from p6c mailing list is fault4.bat at github.com/FROGGS/frame_inc (in case you feel the urge to work on that :o) 09:36

FROGGS STable conflict detected during deserialization.
(Probable attempt to load two modules that cannot be loaded together).
jnthn That .^add_fallback almost certainly should be in a BEGIN. 09:38
FROGGS it was in a INIT
jnthn I'm a bit surprised that you can get it with a linear toplology
Yes, INIT is not compile time!

Replace cargo-culted BEGIN {@*INC...} by use lib

1. less typing and more clearly what it does 2. hides the implementation details of @*INC better 3. more ready for S11/S22 changes hopefully coming soon		 10:11
10:13 kaleem left, kaleem joined
lizmat me suddenly realizes that many of the changes were of @*INC.push, rather than .unshift 10:13
should I add a :last names param to "use lib" that would .push to @*INC rather than unshift? 10:14
or were the @*INC.push cases merely misinformed ?
colomon lizmat: currently my memory of that sort of thing was always about simply getting a directory into @*INC, rather than making sure it was first or last. 10:16
lizmat that's what I figured
my change doesn't break any tests
tadzik timotimo: hm, which rakudo? 10:17
lizmat some of the tests had an interesting way of manipulating @*INC
inside a scope, inside a BEGIN block 10:18
colomon wouldn't be surprised if those go back to the days of pugs. 10:20
colomon doesn't have a particular memory, but certainly has run into lots of crufty old code that's been in roast apparently forever... 10:21
lizmat well, it poses an interesting problem
I mean, "use" is supposed to be lexical wrt to its exports, right?
m: say @*INC; { BEGIN @*INC.unshift: <bar> } 10:22
camelia rakudo-moar fd5f8e: OUTPUT«bar /home/p6eval/.perl6/2014.04-134-gfd5f8eb/lib /home/p6eval/rakudo-inst-1/languages/perl6/site/lib /home/p6eval/rakudo-inst-1/languages/perl6/vendor/lib /home/p6eval/rakudo-inst-1/languages/perl6/lib␤»

lizmat you could argue that the search path for modules is also lexical, the "use" would indicate that
colomon but it clearly wouldn't have been lexical in the old form. 10:23
lizmat but the use of @*INC is causing side effects, making it like that in the whole form
well, I'm not sure what the intent was of putting it inside a BEGIN block inside a scope
s/form/script 10:24
colomon just to get it to happen "first"
lizmat well, yes, for testing it is all ok 10:25
I'm just starting to wonder whether the current implementation of "use lib" leaks in such a way as to be detrimental 10:26
to the scoping that we otherwise have with "use"
colomon ah, yes, that certainly seems like an issue,.
lizmat sub foo1 (|c) { use Foo:ver<1.2>; Foo.new(|c) }; sub foo2 (|c) { use Foo:ver<2.0>; Foo.new(|c) } # this should work in the near future, right? 10:28
now assuming 1.2 needs a different module search path from 2.0
that wouldn't be possible in the current setup, as runtime @*INC manipulation would be visible everywhere 10:29
or am I missing something ?
maybe we need to wrap @*INC into an exported sub and make it have its own lexical copy 10:34
and have module searching use that sub instead of @*INC ?
colomon +1 on the basic idea of supporting this, no idea what the right way to implement it is. 10:36
lizmat assuming we want to be able to lexicalize module search paths 10:37
nwc10 last "win32 parallel testing" message I can spot is www.nntp.perl.org/group/perl.qa/201...13473.html 10:41
jnthn lizmat: We most probably want some kind of way to specify an exit hook 10:42
lizmat exit hook?
jnthn lizmat: A kind of thing like EXPORT, apart from called when leaving the scope that did the "use" statement.
lizmat: So it can undo anything it wishes 10:43
lizmat why would we need that? when exporting a sub to a scope alone already can do what we want ?
jnthn Huh?
I thought you wanted a way to make the @*INC modifications lexical?
lizmat well, I want the *functionality* lexical 10:44
which may mean moving away from @*INC
jnthn Ah, so you solve it by just exporting an updated @*INC var
That's probably easier here, yes.
lizmat essentially, yes
jnthn oh, hm
or is it. 10:45
No, it's harder than that
lizmat I'm wondering as well
jnthn runtime/compile-time confusion.
lizmat why?
jnthn Because exporting a variable is going to affect that's visible when in that block at runtime
But won't influence the PROCESS::<@*INC> lookup at compile time, I doubt...
lizmat but I would be exporting a *sub*
and that *sub* would be asked what the current module lookup path is /are 10:46
jnthn I don't quite see how that helps the module loader?
lizmat not 100% sure either yet,
am a bit handwavy atm
jnthn I may be missing something, but I'm not sure doing it as a sub rather than a var immediatley solves anything...
I can see it working with a compile-time scope exit hook though 10:47
lizmat like a COMPOSE on the block ?
jnthn No, just some magically named sub in the module
This probably also ties into how we'll implement "no"...
lizmat ah, lexical pragma's :-) 10:48
jnthn Right.
lizmat ok, I'll put this on the back burner for deliberation and inspiration
jnthn *nod*
Yeah, I don't have a great answer yet either.
How likely do you think @*INC is to survive the S11/S22 work, ooc? 10:49
lizmat not very likely, as in my view, it's an implementation detail that needs to be hidden
especially compile time / run time confusion that we have in Perl 5 10:50
we need to make more transparent and easier to understand to the lay people :-)
some common error like: 10:51
puhs @INC,'dir'; use Foo
*push
timotimo tadzik: moar
lizmat not finding the right Foo
because the push is done *after* the use
timotimo t.h8.lv/p6bench/2014-05-02-vmnull.html - much graph 10:53
jnthn lizmat: Well, "use lib" is the way to make that easy thing easy, no? :)
lizmat yes, but in Perl 6 we have the added functionality of "use" being lexical in its effects
*except* for "use lib" atm 10:54

akin to IO.close ?
or otherwise, Nil like done/more ?
11:19 jonpads left
jnthn lizmat: I'd guess if the closing thing throws an exception we want that to just be thrown to the closer 11:21
lizmat: We could use true/false though 11:22
true = I closed the tap
false = I didn't because it was already closed
Which may be useful in cases where there is competition to close.
lizmat ok, so if no tappers, False
otherwise True
jnthn It's not "if no tappers", it's "if we removed something" 11:23
lizmat ah, ok (I think)
jnthn can, since we're holding a lock at that point, compute it by knowing size of tappers array before and after
(after attempting to remove) 11:24

Perlito5 - string parser flags \l \u
lizmat with the IO::Notification.watch_path tests 11:25
I ran into the problem of checking the object seen
because the class is lexical inside the other class

to the code, which now effectively lets me check for IO::Notification::Change
jnthn Oh, I'd just remove the "my" in this case 11:26
lizmat my ? there is no my
jnthn ?
Oh
So why isn't IO::Notification::Change already visible?

camelia rakudo-moar fd5f8e: OUTPUT«(Change)␤»
jnthn There it is.
:)
lizmat of course: the problem wasn't the lookup 11:28
the problem was that the class itself doesn't know it is a "IO::Notification::Change"
so it's representation is faulty
(Change) instead of (IO::Notification::Change)
right ?
jnthn I think .WHAT always gives a thing that stringifies to a short name? 11:29
By S12, anyways... 11:30
lizmat m: IO::Notification.WHAT.say
camelia rakudo-moar fd5f8e: OUTPUT«(IO::Notification)␤»
lizmat should that then need to say (Notification) ? 11:31
wasn't the problem that we don't really have class hierarchies yet ? 11:32
jnthn Yeah, I guess so...
Um...what?
No, it's purely a "what is passed as the 'name' parameter to the meta-object" issue
lizmat if IO::Notification had been implemented with class IO { class Notification { } }
it *would* have said (Notification) 11:33
because it only sees its own class definition
jnthn checks S12
lizmat m: class Foo { class Bar {} }; say Foo::Bar
camelia rakudo-moar fd5f8e: OUTPUT«(Bar)␤»
lizmat m: class Foo::Bar {}; say Foo::Bar
camelia rakudo-moar fd5f8e: OUTPUT«(Foo::Bar)␤»
jnthn Yeah, S12 has it as .WHO stringifying to the long name 11:34
Note class Foo::Bar { } is more like package Foo { class Bar { } } really
S12 is actually out of date... 11:35
WHAT the type object of the type, .gist returns MyClass()
It's (MyClass) now...
lizmat but is the spec wrong, or Any.gist(T) ? 11:36
jnthn Neither, I think it wants fixing at the point we construt the meta-object 11:37

maybe the ramps in the graphs come from the previous test exhausting the ram completely, thus kicking out all buffers and then the timing script has to grab itself from disk once more in order to run or something silly like that 11:59

FROGGS jnthn: do you have a hint for me how I can properly rethrow from the handlerscope in nqp::handle? 12:31
timotimo should @foobar.map(*) work? currently it gives "no method count for Whatever"
FROGGS jnthn: do I need to unwind before rethrowing or so? so that I do not rethrow to my own handler?
timotimo: what is the point of this operation?
jnthn FROGGS: Hmm...there should already be stuff in Moar to ensure that a handler never re-catches an exception it's handling. 12:32
Ven_ FROGGS: * xx +@foobar
jnthn Or more precisely, that's what the active handlers thing is about.

12:36 Alina-malina left
jnthn the in_handler_stck bit, yeah 12:36
FROGGS okay, it runs the first handler (a for loop with another label), and then rethrows and does not run any handler anymore
12:37 Alina-malina joined
FROGGS ohh 12:37
dang
since the handler is static for 'for' loops, it can never appear more than once in the stack? 12:38
that is my test: my $x; BAR: for "bar" { .say; FOO: for "foo" { .say; redo BAR unless $x++; } }; say BAR
jnthn Hmm
FROGGS this should print: bar foo bar foo 12:39
it prints bar foo instead, and then misses the right handler
jnthn ah...could be that
in_handler_stack should maybe be considering the actual frame too 12:40
So such recursion works out 12:41
MVMActiveHandler does have a ->frame, and there's one available to pass in to in_handler_stack at the point it's called

jnthn lizmat: Don't feel strongly either way, it's hard for me to know whether it'll prevent folks getting a helpful error when they forgot the arg more often than it'll be a useful shortcut. 16:02
PerlJam (a weak argument but ...) The other forms of .subst() always have a replacement. You can't just go $text ~~ s:g/a/; or s:g[a]; to mean the same as .subst("a", "", :g);

16:10 Alina-malina left
FROGGS jnthn: the latter needs cleanup, like creating a src/core/Label.pm 16:10
masak PerlJam: following recent trends, I propose (tongue-in-cheek) that we rename the latter .SUBST :P
FROGGS jnthn: all is done on moar so far, MapIter needs to be aligned for parrot, and all the stuff needs to be implemented for jvm 16:11
masak PerlJam: because .substr is the "pure" operation, and .SUBST requires you to take care.
16:11 Alina-malina joined
PerlJam masak: careful what you say ... you never know when TimToady might like your suggestions ;) 16:11
masak PerlJam: also because you can't really modify strings, so clearly it's doing something magical.
jnthn Let's make everything that mutates be uppercase! 16:12
:P
[Coke] let's make it cyrllic!
FROGGS also, 'new' really is magical and needs to be NEW
[Coke] .субст()
TimToady masak: as near as I can tell, 'is parsed' ought to be largely orthogonal to whether the macro returns text or AST
masak TimToady: agree.
TimToady the whole point of immutable cursors is that you just pick the one you want to continue with 16:13
PerlJam masak: or ... I counter propose that .subst should really just be .s ;)
donaldh_ github.com/rakudo/rakudo/pull/266 - async IO on JVM.
masak PerlJam: ooh
PerlJam: it's probably too late for that, but otherwise I like it.
TimToady a small collision with IO.s
PerlJam yep 16:14
TimToady and people will try to write .s/foo/bar/
PerlJam yep
TimToady and we really don't want to make it a postfix macro 16:15
PerlJam I just need to train my fingers better. I'm always typing substr when I mean subst, so it bothers me.
lizmat .substitute then maybe, to add to the levenshtein distance with .substr
TimToady then we really would have to spell it .SUBST
lizmat afk for a bit 16:16
TimToady put in fake candidates for .subst and .substr that notice when the args are the wrong type, and suggests the other
PerlJam .search-and-replace
Ulti lizmat++ 16:17
^ for .subst
FROGGS ohh, just realized that nqp-m's for loop do not yet support labels for some reason...
nqp-p does however
Ulti though it is a bit of a weird case, I assumed the "" even though jnthn didn't put it in :3 16:18
but checked out of curiosity
though I would prefer .strip("a") 16:19
JimmyZ hopes there will be a Perl 6 version of Akka
PerlJam Ulti: that seems an unwarranted specialization to me. 16:20
Ulti *shrug* 16:21
I would also do .replace instead of .subst too
though I would also say :a "all" instead of :g which is essentially Perl heresy 16:23
or even :all
TimToady well, if you want heresy, make that the default, and rely on :1st for the other 16:24
changing defaults is real heresy, not bikeshedding the name :) 16:25
PerlJam that would be more huffmanly. I can't remember the last time I've wanted to replace just the first occurence of something.
Ulti yeah I kind of wonder, I usually do global replace, but for one liners its more common not to
PerlJam I would probably be fine if it were called :a/:all and the default. 16:26
FROGGS well, we can change its default whether you're running a -e or not :P
16:27 lvfjf left
TimToady so that's just the default default, but then what's the default default default? 16:27
FROGGS that clearly depends on the os, backend, and strict/lax mode 16:30

16:30 ajr_ left
FROGGS (our moon) 16:30
Ulti FROGGS: lol unpredictable stateful behaviour is perhaps computer science heresy :P

PerlJam Random thought ... do we think that everyone who is reading these announcements will know where to look for more information? I mean we tell them to ask here if they'd like to contribute, but say I don't know what "univals" is for ... should we have links to the spec?

donaldh_ timotimo: catching up with moar :) 20:30
[Coke] ooh, no more permgen! yay!
timotimo i'm glad
permgen?
jnthn donaldh_: Does bytes_supply work on Moar also, ooc?
donaldh_ yeah, the JVM used to have a permgen space for class definitions. 20:31
[Coke] "A third generation closely related to the tenured generation is the permanent generation which holds data needed by the virtual machine to describe objects that do not have an equivalence at the Java language level. For example objects describing classes and methods are stored in the permanent generation."
donaldh_ Continual problems with running out, and no ability to GC.
jnthn It'll not be missed 20:32
donaldh_ jnthn: I did not test on Moar because Moar does not have asyncreadbytes implemented.
20:33 ClarusCogitatio left
jnthn donaldh_: Right, meaning accepting the PR will break the build on Moar? 20:33
donaldh_: Or is it mapped, just not implemented?
donaldh_ Mapped and throws an exception at runtime.

Hmm. building nqp with --backends=moar --prefix=../install --gen-moar puts moar in the wrong place :) 20:50

jnthn Gee, the modules-test in R* goes by a good bit quicker on Moar than on Parrot... 20:53
Anyway, passes for both in that tarball, even after module bumps I did earlier on :) 20:54
So, the release candidate stands.
Will leave it until tomorrow to release, to give time for others to try it.
