lizmat so what is the right way of running a single spectest test-file? 07:58
07:58 fhelmberger joined
tadzik ./perl6 t/spec/test/file? 07:58
nwc10 I thought ./perl6 -Ilib path/to/it 07:59
tadzik or prove -e perl6 (...)
but fudge it first
lizmat you mean, run the .rakudo version?
tadzik yeah
lizmat the thing is, if I run this inside the spectest, I get this: 08:00
t/spec/S03-feeds/basic.rakudo ............................. All 19 subtests passed
(less 5 skipped subtests: 14 okay)
if I run it separately, I get: # Looks like you planned 19 tests, but ran 21
# FUDGED!
FROGGS make sometests TESTFILES=t/spec/... 08:01
08:01 pencilk left
moritz so, it complains about a wrong test plan, or that it ran too many tets 08:01
FROGGS this will fudge too, and then I usually run the .rakudo test directly, to get some output
lizmat Parse errors: Bad plan. You planned 19 tests but ran 21. 08:02
FROGGS++ that generates the test summary report
and indeed… 2 errors
seems it is getting too many "ok 15 - # SKIP double-ended feeds" now 08:03
hmmm...
it says that is both ok, and failed? gist.github.com/lizmat/5574406 08:05
moritz where does it say it's ok? 08:06
all subtests passing is not sufficient for a test file passing 08:07
you also need to satisfy the test plan, and exit with a return code of 0

lizmat aha… ok
08:11 sqirrel joined
lizmat in the section marked "#?rakudo skip 'double-ended feeds'" I only see 2 times is(), yet it generates 4 "ok N - # SKIP double-ended feeds" 08:12
is that expected? 08:13
08:13 berekuk left 08:15 berekuk joined
moritz lizmat: there are two sections that are skipped with 'double-ended feeds', and each contains two tests 08:16
lizmat grrr… duh
so the plan just seems to be wrong
moritz $ ack '\b(is|ok|lives_ok|dies_ok)\b' S03-feeds/basic.t|wc -l 08:17
24
that's what my manual counting also produces 08:18
@data ==> grep {/<[aeiouy]>/} ==> is($(*), $(@out), 'basic test for $(*)');
I'm pretty sure fudged won't recognize lines like these as tests
lizmat grrr: Parse errors: Bad plan. You planned 24 tests but ran 21. 08:20
ok, will look at this after fitness, afk for a few hours
dalek ast: bb94740 | moritz++ | S03-feeds/basic.t:
fix test plan, rakudo fudging

also move a block to the end of the file, because providing a #?DOES seems to confuse fudge for the subsequent blocks		 08:23

lizmat is there a way to have multiple MMD candidates share the same code block? 10:27
jnthn no
lizmat too bad :-)
I guess this is really an optimisation issue, to be handled by the optimiser? 10:28
jnthn Well, depends what you're optimizing for. 10:29
lizmat in this case memory, I would think?
jnthn If it can look at the arguments it's getting to each one and do some inlining specific to each of them, you could potentially come out ahead on speed.
So, it's probably a trade-off. 10:30
(The optimizer already potentially can do that kind of inlining, fwiw.)
(Though it can't do dupe code elimination yet.) 10:31
lizmat well, if the code gets serialized, it would mean smaller bytecode files, so faster startup :-)
moritz fwiw we once had a syntax sub f (signature 1) | (signature 2) { ... }
lizmat I guess that becomes less of an issue with SSD's
moritz that allowed two multi candidates to share the same code
lizmat I think it would be an optimizer thing: developers may not see that the code is the same many times 10:33
otoh, it would mean less maintenance (and less chance of fixing one place where it needed to be fixed in two) 10:34
anyways, just making sure I'm not forgetting obvious things to do
jnthn: would "multi method at_key(Any:U \SELF: $key) is rw {" not also be a candidate for adding a "Mu" type to $key ? 10:35
jnthn lizmat: Hmm...I guess that's the auto-viv one...
lizmat: I suppose yes. 10:36
lizmat will do and test
10:41 rindolf left 10:42 rindolf joined, AMENDEES_ left
Juerd lizmat: Serialised code for faster startup? Not just with SSDs, but with even with a network filesystem that doesn't sound like a useful optimization. Anything will do at least 10 MB/s now. That's a shitload of code. If you have more than that, the startup overhead is probably the least of your worries. 10:42

lizmat: Also, caching will take care of the 2nd and consequent runs. 10:43

FROGGS jnthn: do you have a hint what is going wrong there?
FROGGS fears that jnthn is saying "you can't do it that way"
jnthn I can guess, at lesat. 12:40
FROGGS \o/
jnthn CALLER:: looks a frame out.
When you call a multi then you are actually calling a proto which then does the multi-dispatch.
12:41 denisboyun___ joined
jnthn Really doing that gets costly, though, so a bunch of the time we inline that proto. 12:41
An indirect call through ::(...) thwarts the optimizer, however. So you have to go via the proto.
So in that case there's 2 frames there, not one.
FROGGS I see
jnthn Maybe try DYNAMIC:: instead of CALLER:: 12:42
Or CALLER::DYNAMIC::<$_>

[Coke] I don't know what the rollup summary would look like, but at this point, would a daily dump of the build output from a star build be sufficient? 12:46
jnthn Well, we don't run that much up to that point.

[Coke] (split into files?)
jnthn [Coke]: The test output sounds like the useful bit, though if the build fails that is also useful.... 12:48
moritz jnthn: iirc multiple ~ in one expression are compiled to a listop call; so if one of them isn't known at compile time, nothing is constant folded

pmichaud [Coke]: you need to come to the conference to learn about Perl 6 on the JVM. :)
jnthn pmichaud: "might it be better to simply change the existing candidates to be :$delete where ?$delete"
pmichaud: It would not because the multi-dispatcher can deal with the "required named arg is missing" path rather cheaply. 13:17
lizmat jnthn: this is about my pull request?
pmichaud jnthn: I'm talking about the case where the named are is present but false. 13:18
*named arg
jnthn pmichaud: Yes, but you removed the !
pmichaud: Was that deliberate?
pmichaud yes.
I'm removing the candidate.
[Coke] hurm. "make modules-tests" in star doesn't actually error out when there are errors.
pmichaud I'm removing the !candidate
I'm leaving the existing candidate but making it :$delete where ?$delete"
so that it's only called if :delete exists and is true.
otherwise, it should fall back to the case of ... oh, wait. 13:19
jnthn Yes but then you force a bind check and invocation of the where block.
13:19 Targen joined
pmichaud aren't we doing that in the "where 0" case anyway? 13:19
lizmat I was going for making the special case special 13:20
and the normal case easier, hence no where for the other case
13:20 leprevost joined
lizmat was that a bad idea? 13:20
jnthn If the multi-dispatcher sees :$delete! then it can quickly look and see if we've any matching named arg, and then just disregard the candidate.
pmichaud lizmat: to me, the special case is :delete :-)
jnthn: I understand that part.
jnthn If you make it :$delete then it's an optional named so the fast-path won't work. 13:21
pmichaud okay, I meant :$delete! where ?$delete then
I was thinking of the wrong !
(I was thinking :$delete where !$delete)
Yes, there should be a ! after :$delete
pmichaud adds to ticket.

let chomped do what it is meant for
 13:22
pmichaud lizmat: I tend to think of :!delete or :delete(0) as being the default case (normally we aren't deleting), with :delete being the special case.
thus :!delete or :delete(0) should do exactly the same thing as when :delete isn't present at all. 13:23
lizmat the thing is that I found out the hard way, you can't do a "where True"
pmichaud right, thus ?$delete
lizmat ah, good point
ok, so lose the where 0 candidate, and make the other "$delete! where $delete 13:24
pmichaud well, not yet :)
lizmat that makes sense to me...
13:24 kaleem joined
lizmat ah… :-( 13:24
pmichaud there's a problem with my fallback approach in that if the other candidates don't have a named :$delete arg they'll never match (when we convert postcircumfix to be a sub instead of a method)
unless we add *%_ to all of the candidates. 13:25
(well, all of the fallback ones)
jnthn: opinion on ^^^^
[Coke] github.com/rakudo/star/issues/21 - there's some low hanging p5 fruit. 13:27
jnthn We could add a *% without hosing the inline, I *think*.
[Coke] anyone wants to help get a star release out the door, there's your chance. :)

pmichaud [Coke]++ oooh, nice. 13:28
btw, I'm looking for my p6 tuit level to spike dramatically upward in a week. 13:29
[Coke] \o
pmichaud (it will be essentially zero after today, though)
lizmat: okay, I'd say go with the fallback approach for now.
as in, lose the where 0 candidate, and make the existing ones :$delete! where ?$delete 13:30
lizmat ok, will do that
this also fixes my question of sharing code blocks between candidates, btw, at least in this case 13:31
FROGGS (in a week)++ 13:32
lizmat pmichaud: hmmm… actually, that won't work :-( 13:34
pmichaud adds an "easy" label to star issue #21
lizmat: won't work because...?
(what did I overlook? ;-)
lizmat for exists: then the fall back will not revert the meaning SELF.exists 13:35
so maybe just have one candidate, and handle the value inside the candidate
would that make more sense then?

lizmat was under the impression that having more candidates would allow more work to be done at compile time 13:36
13:36 mtk joined
pmichaud ah, yes... exists changes meaning here. for :exists I'm fine with either separate candidates or a single candidate that handles it 13:36
lizmat and being able to select candidates for :delete, :exists and :!exists at dompile time
*compile
pmichaud while they're methods we can't do much in the way of compile-time evaluation, but when they become subs we will be able to. 13:37
at the moment it might be a slighly premature optimization to try to figure out the best way to go there, though.
13:37 dmol joined
lizmat ok, fair enough, I guess I assumed we were further along then we are in that respect 13:38
the exists candidate now becomes: SELF.exists($key) ?^ $exists
!(SELF.exists($key) ?^ $exists) 13:39
actually
moritz erm
lizmat ?
moritz shouldn't it more like $exists ? SELF.exists($key) : SELF.at_key($key) ?
wait, I guess I should backlog first
moritz goes into hiding again
lizmat no, $!exists is now specced to return true if it doesn't exist 13:40

:!exists rather

lizmat pmichaud: another good point...
jnthn Darn, that adverb parsing was hard work to get right...
:)
pmichaud I'm fine with :kv($kv)... I was just curious if :$kv would work there or not. Go with whatever is easiest to read.
I suspect that trying to figure out adverb parsing cost me about four months in 2005. 13:43
I finally made progress when I decided to not figure it out.
lizmat actual, those :kv fixes were collateral "damage" 13:44
in preparation on fixing :p / :k / :kv / :v
once we have clarity on that
pmichaud yeah, I wonder if :p(0) should be the same as "not present" also. 13:45
so that it can just be the :$p! where $?p thingy
lizmat also, I do think there is a point with having :delete:p
it would easy slicing out pairs from one hash to another 13:46
or is there another idiom for that already?
pmichaud don't know of one... and that one seems "natural"
jnthn pmichaud: Ouch. It didn't take me that long, though I put it off for at least that long. ;)
pmichaud: I had STD to steal from, at least. IN 2005 you didn't so...argh. 13:47

TimToady KeyHashes are supposed to be defined in terms of defaults in any case 17:08

lizmat indeed: for now in the tests for :delete on arrays, I will assume Any 17:14

20:17 ajr joined 20:18 ajr is now known as Guest59475 20:19 Guest59475 is now known as ajr_
ajr_ I was just looking around the code for a place to maintain the record count $*IN.input_record_number() (rakudo/src/core/IO.pm ?) but then two thoughts occurred to me. 20:22
First, this looks like a method, not a variable name. 20:23
FROGGS moritz / [Coke]: I cant install parrot, it tells me the disk is full O.o
ajr_ Second, how to maintain the value, associated with the file - what happens if there are multiple files in/out? 20:24
PerlJam ajr_: aye, it's a method. Is that a problem? 20:25
ajr_ Well, the value has to be maintained somewhere. 20:26
masak ajr_: the method is just a way to return the value.
PerlJam ajr_: the value is kep in the object. 20:27
s/kep/kept/
masak I don't know the answer to the "multiple files in/out" question. the question feels insufficiently specified.
ajr_ The fact it's a method may make the question redundant, though how is the method associated with a particular file? 20:28
[Coke] FROGGS: whoops. I'll see how much of that I can deal with. 20:29
ajr_ There might be a case where you're reading two files, and want the record count for each one.
masak ajr_: it's associated with a filehandle, like $*IO
ajr_: if you've opened your own file, and stored the filehandle in a variable $fh, it'd be $fh.input_record_number() 20:30
ajr_: I'm confused at your confusion :)
20:30 domidumont left
PerlJam ajr_: are you thinking of p5's automagic $ARGV switching when reading the ARGV handle? 20:31
ajr_ So $*IN.input_record_number() would return the count for STDIN?
masak aye.

TimToady wonders if it would make more sense to send the line number with the line in question
ajr_ Is the same input method used for all files, including $IN*, or are there special ones? 20:34
PerlJam ajr_: "same input method"?
20:36 gdey left
PerlJam TimToady: would that imply that the idiom for lines() would change? 20:37
ajr_ PerlJam: I'm trying to find the appropriate place to maintain a record count, which is presumably where the file is read?
PerlJam ajr_: the IO handle that's associated with the file seems like the right place to me.
ajr_: are you asking if there are other IO thingies that read files that aren't also IO::Handles? 20:38

ajr_ The lines method in IO.pm maintains a line count ($count) which could be stored, but slurp doesn't. Is it reasonable to expect a line count for a slurped file? 21:13

raiph ohh, i missed that. just saw the later commit msg, thanks lizmat 22:14
lizmat I wonder how bad it would be to have a separate "multi method postcircumfix:<[ ]>(\SELF: $pos where $pos < 0) is rw {" candidate to fail 22:17
and remove the "fail if $pos < 0" from all the other candidates in Any 22:18
jnthn lizmat: Suspect that way spoils the cache's day too. 22:19
lizmat I guess the optimiser isn't smart enough to skip that candidate altogether when $pos is an uint ? 22:20
jnthn It can't do anything when it's a method call, which it is at the moment.
In the future, they'll be multi subs, and it'll be able to analyse them more, but it's likely to handle the way it is now better. 22:21
Or at least do so sooner.
FROGGS just to confirm: I cant export/import a variable from a module right now, or can I?

FROGGS doing that would be fine too, but it didnt work yesterday when I tried
jnthn You can do enums, it just doesn't export the elements. 22:23
As in, you have to longname 'em.
lizmat ah, yes, it exports the elements if you map $_ to "eval $_", if I remember correctly
