s1n anyone know what get_pmc_keyed refers to (i.e. unimplemented method maybe?) 02:40
03:13 Whiteknight joined 03:15 Ademan joined 03:24 tetragon joined 04:25 tetragon joined
pmichaud get_pmc_keyed is a vtable method 04:33
it's used for looking up entries (e.g. in a hash or array) 04:34
PerlJam good morrow. 05:01
pmichaud good morning 05:09
PerlJam is staying up with a coughing child. 05:13
pmichaud sorry to hear that 05:15
I've had a few nights like that :-|
PerlJam So, what's new in the world? 05:17
05:17 tetragon joined
pmichaud not a whole lot, other than news already reported :-) 05:17
PerlJam I'm still waiting to hear from TAMUCC. The position must stay open until 9/11, so I guess they can't officially hire me until 9/12 05:19
pmichaud sounds like business as usual :-) 05:20
is Cyndi excited? 05:23
PerlJam I think I have some small insight into what it's like to be retired. I keep wandering around looking for stuff to do. I try to do parrot/rakudo things but kids/wife make that difficult. So far I've mowed my sister-in-law's grass, made lots of meals,and generally puttered around their house.
Cyndi is very excited (and happy)
pmichaud well, your insight into retirement somewhat matches mine :-)
PerlJam yeah, but you nominally get to hack on rakudo as your "day job" :) 05:25
pmichaud well, between disability, kids, and travel there haven't been many "days" for my "job" :-) 05:26
(this last week there were some, but I'm apparently still recuperating from this summer :-)
PerlJam I've rediscovered that I'm not "normal". I've been helping Cyndi's sister with her algebra homework (she's going back to school to become a teacher) and apparently I remember how to do it better than her engineer husband. Everyone has been marveling at my ability to do algebra and I've been boggling that everyone is marveling. 05:29
pmichaud shall I send Matthew? he does algebra pretty well also :-) 05:30
PerlJam heh
05:31 chromatic joined
PerlJam greetings chromatic 05:31
chromatic Greetz.
pmichaud, did you see my response to RT #58578? 05:32
pmichaud not yet
I'm looking into something else
chromatic Good; I think I have a simpler solution. (But I blame Rakudo still, not Parrot.) 05:33
pmichaud I'm pretty sure it needs to be max >= min 05:36
the core of the difficulty is that there isn't really a way to find out the depth of the outer stack to know when to stop 05:37
so we keep incrementing until we get an exception
although I suspect we don't need to do $P0 = getinterp at each iteration. 05:38
nopaste "chromatic" at 63.105.17.30 pasted "Another Attempt (Less Confusing)" (21 lines) at nopaste.snit.ch/13959
pmichaud I wanted to have the ability to specify a range of depths to search 05:39
thus the min/max approach
chromatic This still uses min/max, but it doesn't increment depth and decrement max every time through. 05:40
pmichaud except depth needs to be offset by one from min-max 05:41
I want min and max to be relative to the caller, not to !OUTER
i.e., a min of 1 would be !OUTER's caller's caller 05:42
chromatic but depth starts at min and goes up to max 05:43
pmichaud depth starts at min + 1
and goes to max + 1
chromatic Right, min + 1
I don't understand why you decrement max every iteration though.
pmichaud I think I was tired when I wrote that code. :-) 05:44
chromatic I can change it so it goes to max + 1 and test; doing that now.
I kept getting the impression it walked out of the range and the exit condition was never true. 05:46
PerlJam seems like the way it is will never go from min+1 to max+1, but rather from min+1 to int((max+min)/2)
pmichaud in the original source? no, because it's comparing max to min 05:47
not to depth
and min doesn't change
PerlJam oh, right.
chromatic No crash with my latest change. 05:48
pmichaud interesting. I'm surprised it makes a difference.
PerlJam perhaps there's an obscure bug in parrot's inc/dec ;) 05:49
chromatic My backtrace was over 10,000 call frames deep.
Sorry, 100,000.
pmichaud I don't quite understand what was generating the call frames.
nopaste "chromatic" at 63.105.17.30 pasted "Yet Another Rakudo Seggie Patch" (26 lines) at nopaste.snit.ch/13960 05:50
chromatic Exception handler invocations at first, until it exhausted Parrot contexts, and then recursive context marking.
pmichaud "exception handler invocations"? from...? 05:52
chromatic No caller depth exceptions. 05:53
pmichaud but weren't they being popped at the done: label?
or do you mean "No caller depth" exceptions? 05:54
chromatic Yes.
i mean the exceptions, not the handlers
pmichaud so, when the caller didn't have an :outer, it would generate an exception 05:55
chromatic I believe so. 05:56
pmichaud ...and the exception never gets gc'ed?
or...
I'm really confused.
chromatic The exception handler causes another exception to be thrown, which causes another exception to be thrown, which... 05:57
pmichaud which exception handler?
that's the part I'm confused about.
chromatic I'm not sure. It's really hard to tell. 05:58
pmichaud I would've thought that the push_eh on line 91 would be the exception handler for the "No caller depth" exception.
chromatic If I could reproduce it in a few lines of PIR, I could tell you for sure.
PerlJam chromatic++ for plumbing the depths of confusion anyway. :)
pmichaud at any rate, I _really_ don't understand why changing the indices makes any difference. :-) 06:00
and that scares me a bit. 06:01
chromatic Me too.
pmichaud feel free to apply the patch, though 06:03
I do prefer your approach to iterating depth 06:04
chromatic Let's see how many passes we get this way.

nopaste "PerlJam" at 24.243.121.169 pasted "Is there an easier way?" (41 lines) at nopaste.snit.ch/13961
PerlJam pm: see the paste.
pmichaud looking
PerlJam I just implemented the optional exprs in loop(;;) 06:18
pmichaud I think it ought to be simply if $<e1>
instead of if $<e1>[0] ne '' 06:19
PerlJam just trying to be more explicit there (and remind my self that thingy? is an array)
pmichaud I feel that explicitly testing strings here is not the right way to go 06:20
for one, $<e1>[0] will stringify its AST
PerlJam hmm
pmichaud because any match object stringifies as the stringification of its result object 06:21
06:21 tewk joined
PerlJam okay, so I guess I should change the if $<eee> test too (and I'm pretty sure the original implementation did not compare agains the empty string) 06:23
pmichaud I would do
my $block := $($<block>);
er, actually
PerlJam but, what I was really wondering was if there was a better/easier way to generate the empty statements
pmichaud start over
my $past := $($<block>);
PerlJam (or even the always true)
pmichaud if $<e3> { 06:24
$past := PAST::Stmts.new( $past, $($<e3>[0]) );
}
my $cond := $<e2> ?? $($<e2>[0]) !! PAST::Val.new( :value(1) ); 06:25
PerlJam aha! NQP groks ternary. I had though it didn't for some reason.
pmichaud $past := PAST::Op.new( $cond, $past, :pasttype('while') );
if $<e1> { $past := PAST::Stmts.new( $($<e1>[0]), $past ); } 06:26
make $past;
we added ternary to NQP a few months ago... originally it didn't.
anyway, we only add the $<e3> and $<e1> nodes if they're non-null. 06:27
the other way to make sure we matched something other than empty string is to use $<e1>[0].chars 06:28
I _think_ .chars has been implemented on match objects 06:29
yes, it has.
PerlJam well, I'll play with rearranging things a bit. That'll at least help me get back into the feel of rakudo again. 06:33
pmichaud okay.
PerlJam does NQP understand the modifier form of if/unless while/until, etc. ? 06:38
pmichaud no.

moritz pmichaud, chromatic: now that test dies after 562 for me 06:43
pmichaud yes, I didn't think it should have that big an impact.
I'll have to look at it in the morning though. About to submit a patch for testing and then time for sleep 06:44
chromatic moritz, do you get an error in can() ?
moritz I'll try to skip that to see if it's the individual test, or more of a complexity problem
chromatic: no, segfault
pmichaud also, for that test I'd prefer that it read the rx_* files and process the skip markers from there 06:45
chromatic Hm. Let me back out a PGE patch and see if that changes things.
moritz would you want skip markers for all Perl 6 implementations in the rx_* files? 06:46
chromatic Sorry, PCT.
pmichaud moritz: they're already there
at least for pge and pugs
nopaste "chromatic" at 63.105.17.30 pasted "Fiddled with this in PCT Debugging It as Well" (15 lines) at nopaste.snit.ch/13962
pmichaud chromatic: shouldn't any locally-set exception handler automatically be popped when leaving the current sub ? 06:47
chromatic I can never remember what's the new system and what's the old system. 06:48
Some PCT code has the generated pop_eh, and some doesn't.
pmichaud I agree it doesn't hurt to have the pop_eh there.

moritz purl, forget tests that 07:22
purl moritz: I forgot tests that
PerlJam Is there a more useful visualization of the results of "make spectest" ?
moritz PerlJam: make spectest_regression instead
that runs everything that should work right now 07:23
(if that help you)
cotto_home and it's back
PerlJam moritz: aye, thanks. But now my question is "Is there a more useful visualization of make spectest_regression?" :)
moritz PerlJam: not that I know of 07:24
PerlJam: what would you like to have visualized? it should be boring ;)

PerlJam moritz: But when it's not boring, not only should it be exciting, but ueberhelpful if it can :)
moritz, chromatic: thanks for that too.
moritz PerlJam: you mean like a HTML matrix? 07:26
pmichaud I'd like to see the progress graphs also show the size of the spectest suite in a light gray
chromatic purl, forget : failures
purl failures are wierd; dying on a call that works in the 00 file.

PerlJam moritz: if it itches enough, I'll scratch it. 07:27
pmichaud (and the size of the spectest suite is in the csv file)
anyway, sleep time here
bbiaw
if people want to play with spectest_regression in the 'failthrow' branch that could be interesting and helpful 07:28
chromatic cotto_home, if you find other open tickets where the last note is me applying a patch, feel free to assign them to me and resolve, or just resolve.
pmichaud (i.e., run "make spectest_regression", and then look at the test file(s) that are reporting "use of uninitialized value" and figure out if it's true or not)
in particular, I'm wondering if 07:29
is($foo, undef, '$foo is undef');
should throw an exception if $foo is uninitialized :-)
chromatic Is that a rhetorical question? 07:30
moritz pmichaud: on the Perl 6 level?
pmichaud moritz: yes.
moritz: in the test suite.
moritz pmichaud: if we have warnings, and a kind of 'use warnings FATAL => ':all'' in place, yes 07:31
07:31 cosimo joined
pmichaud there are a lot of is($foo, undef, '$foo is undef'); in the spectest suite, and I'm wondering if we need to change those tests or if that's a valid mechanism for testing for undefness 07:31
moritz (but tests like that are really wrong anyway)
yes, they should be !$stuff.defined
ok !$foo.defined, ...
pmichaud okay. I need to get .defined defined in Object then 07:32

pmichaud but it'll have to be tomorrow... too tired to reliably do it tonight

PerlJam pm: that's what you get for being wiki wiki :)
chromatic .defined should be easy to add, right?
Just check against Undef?
pmichaud there is no Undef :-)
chromatic Even easier. 07:34
purl i guess even easier is to serve different CSS documents
pmichaud and it's a bit tricky because we also want the vtable methods to dtrt
so, we need a vtable method that delegates to the .defined method
chromatic Okay. If it's more than four lines I might sleep myself instead.
pmichaud and then .true and get_boolean need to be properly defined in terms of .defined
it's more than four lines. 07:35
might be as few as eight, but definitely more than four. :-)
moritz ;)
sleep well
pmichaud and it's intricate enough that I'd rather do it when I'm thinking clearly so I don't do bad code like the stuff we found earlier :-|
PerlJam pm: before you go ... what's needed to make next/last/redo work? 07:36
or, where would I look for more info?
pmichaud they have to be added into PCT so that the various loop constructs can trap those control exceptions and dtrt
moritz I think we should have control exception in PCT
pmichaud and for that we also need things like "next LABEL" which means the loop and block constructs need to be able to recognize the control exceptions that have their label 07:37
(and the control exceptions need labels)
we already have control exceptions in PCT -- that's how 'return' works
we just need to add the cases for next/last/redo etc. 07:38
moritz envisions a :catches<name1 name2> syntax, so for example a while block would be set up to catch <<last redo next @labels>>
pmichaud something like that might work. More likely is :label('FOO') and just catch all of the control types 07:39
moritz but it shouldn't catch return 07:40
so not "all"
pmichaud it'll end up catching it and rethrowing it because it's not one of the recognized control exceptions
afaik Parrot doesn't give me a way to say "only catch these types of exceptions" 07:41
at some point it's supposed to allow us to mark exceptions as handled or unhandled, but I don't know if that's implemented yet.
anyway, sleep 07:42
purl i think anyway, sleep is necessary before I cough up lej's lungs some more
PerlJam purl: forget anyway, sleep 07:43
purl PerlJam: I forgot anyway, sleep
chromatic pmichaud, if you backlog, I think you set a type for the exception handler 07:47
though the syntax for that I don't remember

lemme see
NotFound Real module, will be better.
Xlib is not exactly a simple test case. 16:17
particle i have a diff from trunk to gsoc_nci_001 16:36
i'm looking through it for pod and other docs
NotFound: compilers/ncigen/t/ has some examples 16:41
you need only to look at the test library to see how to use ncigen 16:42
NotFound particle: I'm unable to understand uncommented complex perl code in less that one life ;) 16:49

moritz 159748896 / 1024 / 1024
purl 152.348419189453
moritz is more impressed that 150MB were exported without error 17:15
measuring speed of things that are not optimized isn't very interesting
(I still do that sometimes ;) 17:16
NotFound Is a better test of parrot and nci stability that way, building and discarding a lot of objects.
particle optimizing things you haven't measured the speed of isn't very productive
NotFound So, the idea that a simple mysql module is doable has been reconfirmed :) 17:17
moritz mysqldump takes 35s for the same table 17:18
so it's not that bad ;)
particle 74/35
purl 2.11428571428571
NotFound moritz: I know of a guy that optimized for speed a loop until key pressed. 17:19
particle 211% slower
moritz NotFound: there's no limit for creativity 17:20
NotFound Let me avoid the pessimization for a nicer comparaison.
particle s/creativ/stupid/
moritz particle: not 211% slower. It takes 211% of the time, so it's only 111% slower
particle oops, finger slipped. yep! 17:21
NotFound There was an example to instruct another guy, but a fantastically bad choosen example.

moritz running with -G makes it even faster: 1m6s (and uses only about 1.2GB ram ;)
Tene NotFound: now I get a segfault. Is that better? 17:29
NotFound moritz: it's using the mysql function to retrieve all data in a shoot, no wonder it eats a lot of memory.
moritz Tene: did you adapt the connection parameters? 17:30
Tene Nope.
moritz NotFound: yes, I figured...
NotFound Tene: please -t and tell me where dies.
Tene moritz: what params should I set to what?
moritz Tene: the connection params to the DB in the pir source 17:31
Tene: search for real_connect
Tene moritz: what should I set them to? I don't know where this db is.
moritz Tene: you can use any mysql db that you have access to
Tene ah
moritz then search for select, and edit that line to use a useful table name 17:32

NotFound How can I know the size of an Array PMC in rakudo? 20:49
pmichaud .elems ? 20:51
NotFound Method 'elems' not found for invocant of class 'FixedStringArray'
pmichaud oh, is that @*ARGS ? 20:52
NotFound No, is a test of a pir module.
pmichaud Rakudo doesn't have an equivalent of FixedStringArray. However, you could try simply evaluating it in numeric context -- i.e., +@array
NotFound get_number() not implemented in class 'FixedStringArray' 20:54
pmichaud what is creating the FixedStringArray?
NotFound Theres is an integer context?
pmichaud Perl doesn't really have an integer context, no.
NotFound pmichaud: is returned from a method call.
pmichaud NotFound: from a Parrot builtin type, or from something else? 20:55
NotFound From a pir module. The value returned is a FixedStringArray.
pmichaud well, this is an example of cross-hll types, then. :-) 20:56
I don't have a quick answer, other than FixedStringArray should probably provide a get_number vtable entry. Most of the other Parrot array types do.
NotFound I'll try with resizable one. 20:57
Tene Should FixedStringArray have a .elems()? 21:03

It works if I add a get_number vtable function to FixedStringArray. 21:23
particle notfound: does "my Mysql $mysql .= new();" work? 21:40
jonathan my Mysql $db .= new(); # reads so nicely :-)
particle is $row not already a number in "my $elems = +$row;" ?
ah, $row is an array, i suspect 21:41
jonathan I doubt my Mysql $db .= new(); will actually work, though.
NotFound particle: yes, is an array.
jonathan Because it's calling the new() sub in a namespace.
NotFound What must be provided to make that work?
A 'new' sub in the class namespace? 21:42
jonathan NotFound: I believe, register it with p6meta, which will make a proto.
particle yeah, that'll do it
NotFound I'm now making a Mysql::Row class, to simplify. 21:43
jonathan is very happy to see this starting to work :-)
particle that inner while loop can be replaced with a map statement (or many other things)
jonathan Will certainly do some more Rakudo stuff in the next couple of weeks than I have in this last week. 21:44
NotFound particle: I left that for you rakudo guys.
particle and $row := $r.fetch_row... don't need the colon
NotFound I'm just trying to make Mysql to work.
particle yes, it's ugly perl 6, but it is valid perl 6 :) 21:45
NotFound The +$row is a valid thing, then?
particle yes, but $row.elems is probably more clear 21:46
NotFound Are you sure pmc arrays have that method?
particle if you use RPA it will
NotFound RPA? 21:47
purl hmmm... RPA is parrot's generic array, you can call push, pop, shift, unshift etc on it.
particle ResizablePMCArray 21:48
rather than FixedStringArray
Tene But should FSA have .elems? 21:50
NotFound I don't see that method in resizablepmcarray.pmc nor in fixedpmcarray.pmc 21:51
particle perl 6 should wrap RPAs as Perl6Arrays 21:56
and Perl6Array has .elems
but RPA does have .elements which it inherits from FPA 21:57
but i hope that's not exposed to perl 6, because it's not valid perl 6
PerlJam Better would be to DBDI to work :) 21:58
NotFound The Mysql $mysql .= new(); gives: Method 'ACCEPTS' not found for invocant of class 'Mysql' 22:00
PerlJam speaking of which ... is anyone working on dbdi?
NotFound dbdi?
PerlJam ask google, it'll tell you everything you need to know. 22:01
