[Tux] Inline::Perl5 till broken 08:35

nwc10 jnthn: for NFG, I'm wonder if a viable "hybrid" approach is to implement >1 "global" NFG table. So, when comparing two strings, if they share the same table, memcmp() and be done 08:45
nwc10 and only actually use 2 or 3 if the first table is heavily used 08:46
but, as we found with Perl 5 hashing, attempting to build something that reacts when it detects that it's "under attack" actually gives new things to attack 08:47
jnthn nwc10: Trouble is that makes every string a pointer bigger, to point to the table.
nwc10 yes, I sort of realised that as I was typing. At least "will need a pointer, so that we know when to GC the common tables" 08:48
jnthn But generally, we should make this work first in the easiest way possible so we can assemble a decent test suite, before we go on to smarter schemes.
nwc10 "simplest thing that could possibly work"
[then you typed that]
"simplest thing that could possibly work" is a global table
jnthn Right, which is hwy I'm starting there 08:49
timotimo i'm still aching to have something in place that reduces the number of duplicate MVMString instances ...
jnthn Also, we could cap the number of allowed combiners.
There's precedent for that in the Unicode standard.
nwc10 the *other* thing about attacks, is to figure out theoretical attacks that would take out a single table, but would be successfully mitigated by something more sophisticated
timotimo which can also lead to faster comparisons, as MVMString tries pointer compare first
nwc10 IIRC it's 32
timotimo my lord ... the combinatorics ... 08:50
nwc10 at least, for one of the specified interchance formats
jnthn Well, the actual answer is that Unicode itself doesn't spec a limit, but the safe text streaming thing in the annex about normalization forms picked 30.
nwc10 but, I think that there are enough permutaitons of "1 base character" and "1 combining thingybob" to get you well beyond 8G
ah 30, not 32 08:51
timotimo right, 1+1 already gives you a metric ton of combinations :S
nwc10 but if $num_base_chars * $num_single_combining_things is a metric ton of pain
jnthn I suspect 30 'cus 32 bytes is a conveneient computer size, and for normalization you need the base char, the combiners, and the next base char...
nwc10 then the 30 limit doesn't hlep you
jnthn Well, we don't have to pick as high as 30.
:)
nwc10 but we're not allowed zero? 08:52

I also really need to rewrite the intro to feel less "rushed", and be more like a tutorial. Maybe this'll be less fitting for learnxiny.com, but I love the code-as-documentation format... 09:52

RabidGravy are there any modules on the list that just provide roles? 12:08
psch RabidGravy: OO::Actors provides a declarator that creates classes that have a role mixed in 12:12
it's not quite only a role, but might fit whatever you're looking for 12:13
RabidGravy let's look
Ven (also OO::Monitor) 12:17
nwc10 jnthn: ^^ should be gitlab.com/nwc10/nqp.git 12:18
jnthn FROGGS: I get some fail in 15-rw-args.t but let be re-build latest stuffs before I pester you about that. :) 12:19
FROGGS: Hmm. "Native call expected argument that references a native integer, but got P6opaque" 12:21
I think I have latest everything but let me do clean builds
awwaiid "Substitution now supports assignment meta-op, e.g. s[\d+] += 2" *mindblown* 12:22
(catching up)
FROGGS jnthn: I have no local changes and it passes :/ 12:25
jnthn FROGGS: Oh, somehow an earlier nqp pull failed, so almost certianly false alarm. 12:30
tadzik RabidGravy: roles are pretty much core 12:36
RabidGravy it was more of a question is if one was to make something that provides a role or roles for user classes to consume is there a naming convention 12:38
tadzik ah, hmm 12:40
I don't think there's any; my github.com/tadzik/ClassX-StrictConstructor/ is a role and I had no complaints about it :)
RabidGravy I guess these are things that will emerge as the ecosystem flourishes 12:42
psch i'm not sure what kind of convention there could be
if anything i'd say "if you're unsure call it FooRole"
RabidGravy well like Role::Foo or something
psch oh, a top level role namespace for the ecosystem 12:43
RabidGravy yeah perhaps, it might allow for some future organisation based on what kind of thing it provides 12:44
or is that too prescriptive for the time being
psch fwiw, i think the OO::Actors approach is great, exposing a declarator that always applies the role to the declared class makes it clear there's something special happening
FROGGS RabidGravy: since Roles are things one can *do*, they potentially should be verbs
psch of course it wouldn't work with anything that wants multiple roles applied, unless you create that declarator in-project 12:48
tadzik there's no naming convention for classes, I don't think there's a need to have one for roles
RabidGravy on the flip side having "class Foo does Role::Zub { .... }" seems somewhat redundant
tadzik oh, there's an idea to use different word types 12:49
so grammar makes sense, like 'class Dog does Wagging' or something
or Storable 12:50
or something
RabidGravy yeah verb-like for roles, noun-like for classes 12:52
jnthn FROGGS: Yeah, with latest NQP it works fine. Sorry for the false alarm :) 12:57
FROGGS jnthn: no problem :o) 12:58
jnthn fwiw, I'd rather we don't evolve a convention of putting Role in the name of roles. 13:18
It's annoying enough in .Net when exceptions get Exception on the end...
psch meant it more as a last resort
but i can see having it happen at all means people adopt it when it might be unneccessary 13:19
masak IMNSHO, roles should be named such that `does <rolename>` reads nicely. 13:20
jnthn +1 13:23
shoppin'
FROGGS aye, that is what I tried to say too 13:24

lucasb I get a different error on my console: "Cannot call 'subst-mutate'; none of these signatures match ..." 14:57
I mean, plain match can coerce to string, but substitution can't coerce to string. 14:58
lucasb Maybe it makes sense; you can't substitute a substring inside something that is not a string. The compiler would have to change the type of the variable. 14:59
psch m: say 42.subst(/\d+/, "xxx") 15:07
camelia rakudo-moar d76ea8: OUTPUT«xxx␤»
psch lucasb: something seems inconsistent here. to me, s/// is mostly an operator form of .subst (or the other way around)
except s/// is the op form of subst-mutate, to be explicit 15:08
s/// dying on numeric input complains about not having a dispatch candidate for Int when run with --ll-exception, although the proto is with Cool 15:09
maybe "we don't mutate" is enough reason, although i don't buy the "[it] would have to change the type" argument 15:11
because we don't need to change the type to mutate, we need to change it to match in the first place 15:12
psch oh, now i see lucasb++ saw the dispatch failure too 15:17
TimToady surely the mutating form should be trying to replace the contents of the variable, not fiddling with what's inside the variable 15:18
s:g/variable/container/ 15:19
TimToady fwiw, subst-mutate is the only method in core that attempts to declare $self is rw: 15:35
TimToady but it's in the Str class, so doesn't know how to dispatch Int 15:38
TimToady will play with moving subst-mutate to Cool
lucasb psch, TimToady: Thanks for taking a look at it. (I was away) 15:43
TimToady now fails deep in find_best_dispatchee when trying to match Junctions, but I think it doesn't try that unless the naïve binding has already failed 15:49
TimToady (and that's a failure trying to compile the setting, so maybe a circularity issue) 15:50
Ulti the new multi line REPL doesn't play so well with my slang it gets stuck forever waiting for a statement to end :( 15:59

ugexe 'rooms' isnt a hash key
its 'room'
next time, try %json.perl to see the data structure 17:09

RabidGravy :)
japhb I went from ~200-300ms (depending on exact build, whether lazy serialization was working, and so on) to ~610-635ms.
FROGGS japhb: and there are no dangling processes currently? 19:36
japhb Not that I can see, but I am getting some VM pressure from Chrome. Let me shoot that process and see if it's just a matter of an unhappy memory manager
[Tux] nine_, FROGGS, will the performance also return? 19:42
FROGGS [Tux]: I... don't think I've todo something with a performance loss... 19:43
japhb OK, cleared out a boatload of RAM, trying again ... 19:44
[Tux] neither do I, but it is sad to see performance loss where other parts are said to speed up
FROGGS hmmm
japhb Yeah, best I can get right now for 'time perl6-m -e 0' is .602s
[Tux] drop happened between 20150223 and 20150305 19:45
FROGGS februrary? O.o
[Tux] bedtime. we had a 20 km hike today. tired now
japhb [Tux]: The startup time problem is more recent.
Like in the last week or less, I think
[Tux] japhb, it is not startup time that dropped
japhb Ah, is this the lexicalref performance loss? 19:46
FROGGS [Tux]: then please report some code that was faster back then when you get a chance
[Tux] github.com/Tux/CSV/blob/master/README <= code did not change
japhb FROGGS: I thought there was a known drop, which timotimo++ had tried to fix, but got stuck, and jnthn had not had time yet to figure out the problem. Mind you, I could have missed where it was resolved. 19:47
[Tux] github.com/Tux/CSV/blob/master/csv-ip5xs.pl <= that is all the code
$ time perl6 csv-ip5xs.pl </tmp/hello.csv 19:48
went from 6 seconds to 15
anyway. really bedtime now
FROGGS japhb: ahh, the native ref introduction wrt lexical something... that rings a bell
[Tux]: gnight
japhb I'm weirded out by the sudden startup slowdown though. That just doesn't make a ton of sense to me. 19:51
Could it be that with panda/eleven merged, we're following startup CUR paths we didn't hit before, that are in need of some TLC?
FROGGS japhb: I'm at 0.315s on a core i5 laptop 19:52
japhb: the CUR::Installation stuff only gets involved when you actually load a module you installed via panda
japhb FROGGS: What did you get with 2015.03? And have you installed a few modules with panda/eleven in your latest build?
FROGGS let me install something... 19:53
timotimo japhb: the known drop would probably not be that visible in startup speed, i think 19:54
timotimo visited the local zoo today
japhb Ah, gotcha 19:55
Good zoo?
japhb has been to too many bad zoos, and not enough really good ones.
timotimo i'm not sure what makes a good or bad zoo
i haven't been to many zoos in my adult life 19:56
japhb timotimo: Takes good care of the animals, gives them lots of space and time off from constant humans, separates predators and prey enough not to scare the bejeesus out of the prey, and so on.
timotimo ah
in that case, it's a ... medium zoo? 19:57
japhb Fair enough./
timotimo there's a very visible size difference between old cages/areas and new ones
the predators and prey animals are properly separated as far as i could tell
timotimo i couldn't see any indication of not good caring 19:59
two of the three polar bears were sort of stuck in an infinite loop of behavior, which scared me
but instead of worrying too much about something i can't do anything about, i was able to distract myself by looking at the cute animals they had there 20:00
FROGGS japhb: confirmed, the startup time increases the module module I install into a CUR::Installation repo :/
japhb: and tbh, I expected penalties like that
timotimo you mean "the more modules you install"? 20:01
so it could be json parse time?
FROGGS I'll think about a solution
timotimo: aye and aye
timotimo we have basically JSON::Tiny in there, right?
because that thing is sort of ... slow 20:02
FROGGS correct
timotimo dreadfully so :(
skids Aren't the dep md5s stored in the binary compunit? Why is json being parsed for other-than-panda purposes? 20:03
*sha256s
FROGGS it could also be about IO::Path stuff, because IMO it absolutifies paths to the installed files
FROGGS skids: to locate a comp unit by dist name, author and version 20:03
skids I thought that was done during precomp and cached in the CU by sha256? 20:04
FROGGS but your script does not get precompiled, so you have at least one entry point 20:05
skids ah.
japhb Why aren't scripts precompiled?
skids Well, they are if you do it by hand. 20:06
FROGGS japhb: for one because we don't have automatic precompilation
japhb Sigh.
FROGGS and we can only load precompiled modules as of now
japhb mentally increments the number of times he's wanted precomp -> caching
FROGGS I mean, you can precompile a script but then you have to load it as: perl6 -Mmyscript -e1 20:07
japhb Gotcha.
OK, so that's back to the question of why we're parsing JSON at startup. This feels like the kind of thing that wants to be something (much) faster. 20:08
FROGGS aye
the solution we are aiming for is to a) not output json but a perl 6 hash, and b) precompile that hash and load it as long the precomped file is valid 20:09
with a fallback to the hash's source file
japhb Hmmm 20:11
Is that likely to land before 2015.04? 20:12
FROGGS hmmm, the chances are good I think 20:13
japhb Ah, that's good at least. 20:14
skids Could we just throw the parse-to-json-objects in a BEGIN statement in a surrogate module and constant-fold it? 20:16
timotimo how much moreinput do we actually have?
japhb skids: Not a bad idea, that. 20:19
ugexe in the future, will module uninstallation be handled by CompUnits as well? 20:25
we already have some manifest/uninstall stuff, but not sure if its something we should bother with further 20:26
skids ugexe: what you're too good for rm /share/perl6/site/?? ? :-)
psch timotimo: the state of moreinput in nom is "it should work if it's one block that gets broken up by newlines", more or less 20:27
FROGGS ugexe: since CUR's handle installation they should also handle uninstallation if that is possible for that CUR
ugexe well its hard to know i need to delet '/share/perl6/site/37' if i want to unisntall panda
skids agrees 20:28
ugexe and usage messages like: /home/nickl/.rakudobrew/moar-nom/install/share/perl6/site/37 [--notests] [--nodeps] install [<modules> ...] -- Install the specified modules 20:29
FROGGS deleting such a file would not be enough anyway... you need to unregister it as well
psch timotimo: i'm stuck, because it's still a bit of a mystery to me how exactly statementlist keeps track of nesting 20:30
ugexe right
timotimo ah 20:32
psch (at least i think that's why i'm stuck. it's a bit hard to tell with these things sometimes...) 20:35
timotimo oh, crap, installation busts usage messages? i thought we had wrapper scripts for that, but it could very well be that those just exec a new perl6 perhaps?
AFK for a bit 20:36
skids Wait, where is panda installing the uncompiled source nowadays? 20:37
japhb Oh, as a further push to "we should land a performance fix for the startup problem before 2015.04" -- I just realized that startup increasing based on number of modules installed is going to make startup after installing Task::Star rather painful.
FROGGS skids: also to site/ 20:38
skids: look at site/MANIFEST
skids Wait ouch the souce is in decimal file names as well? 20:39
I guess with auths you have to but.
FROGGS well, the idea is that storing things is up to the used CUR 20:43
RabidGravy on a rough test startup is only a tad slower than a week ago 20:46
japhb RabidGravy: Highly dependent on how many modules you have installed.
FROGGS RabidGravy: well, without any module installed it is at 0.315s, and with 27 dists (116 files) it is at 0.485s 20:47
RabidGravy with the same modules 20:48
japhb I also wonder if this is defeating lazy deserialization again (pulling in too many lazy dynvars)
TimToady what's a lazy dynvar? 20:51
FROGGS a dynamic variable that's initialized on first use 20:52
we have proxies in rakudo that replace themself 20:53
TimToady if these proxies are themselves dynamic, could be be replacing them over and over in different dynamic scopes? or are they primarily in PROCESS or GLOBAL? 20:54
*could we be
FROGGS they live in PROCESS or GLOBAL 20:55
japhb TimToady: See 'git grep INITIALIZE_DYNAMIC' for a list
(That doesn't say where the are, just which dynamics we're doing this to.) 20:56
TimToady I wonder if maybe we're overusing the one-per-frame cache
japhb TimToady: one-per-frame cache? 20:57
TimToady see try_cache_dynlex in frame.c 20:58
TimToady at one point we were looking things up 20 frames deep on average, and that cache reduced it (at one time) to about 5 frames average 20:59
but I'm sure we can do better
especially if we're filling up the caches with the "wrong" dynvars
TimToady we really only need to station a (larger) cache at each frame that actually sets a dynvar, and the rest of the frames could just pass along a pointer to that frame's cache 21:01
so you'd only ever visit the frames that actually set a dynvar
and there would "always" be room to cache any dynvar there 21:02
so it might scale a lot better with heavy dynvar use
japhb Yeah, agreed. With only one dynvar cache slot per frame, I can easily see that getting full along fairly deep frame stacks real darn quick. 21:04
TimToady and if the names are authoritative enough, you never even have to look into lexpads, you just follow each cache to the next one till you find the dynvar, hoist it to the top-level cache if you decide it's "hot"
japhb (Where by 'deep' I mean two-digit depth)
TimToady anyway, that's one of my lines in my personal todo file 21:06

TimToady like that
@ only flattens if bound to a slurpy parameter
psch next i'd have asked what "as a reference" means here
TimToady the rest of the time, it effectively already is a reference
P6 doesn't have references like P5 does 22:42
TimToady on the flip side, every object is already a reference 22:42
ugexe github.com/rakudo/rakudo/blob/2cd9...it.pm#L110 | :$INC = @*INC... and later CREATE-INCLUDE-SPEC(@$INC)
i guess is confusing me 22:43
TimToady the @ is unnecessary in the CREATE-INCLUDE-SPEC(@$INC), since the sig for that routine is (@INC), which is not a slurpy, so you can perfectly well bind $INC directly to @INC 22:45
likewise the first $INC just takes @*INC as a reference already for you 22:46
ugexe hmmm. something funny is going on. inside create-include-spec, that nqp::istype($_, CompUnitRepo::Locally) is returning true when it shouldnt be (and thus calling .short-id which doesnt exists for the values i passed to CompUnit.precomp(:INC("some/path")) 22:47
but at least i know its not that now 22:48
TimToady sneaky derivation chain to CompUnitRepo::Locally maybe? istype is not testing === 22:49
ugexe well im testing the :@INC im passing by iterating each value and doing that nqp check. they return false for all items
it happens after passing to CompUnit.precomp(:@INC) 22:50
No such method 'short-id' for invocant of type 'Str' (or 'IO::Path' depending on what ive tried)
TimToady are you suggesting that precomp is clobbering @INC?
ugexe im not sure im smart enough to know what im suggsting :) but if i explicitly pass in an empty array it doesn't happen 22:52
and the error changes between 'Str' and 'IO::Path' depending on what i populate the array with
TimToady hmm, I don't understand the :$INC = @*INC, line in the call 22:53
looks like there's a missing -> before the argument list 22:54
ugexe there are no tests/roasts for that afaik
TimToady so I have no idea what it thinks it's doing with the --> outside a signature
I think you should add a -> before the :$INC = @*INCline 22:55
ugexe the --> Bool is inside the signature though? doesnt that mean it returns a boolean? 22:56
TimToady I don't see a -> in your gist
but I have no idea how it could even parse without one 22:57
ugexe correct, just the -->... you said outside a signature i thought you meant you thought the --> was not inside the signature
s/...//
TimToady I don't see a signature there, if there's no ->
it's parsing the --> as a negated lambda - -> Bool { 22:58
m: my $foo; :$foo = 42; say $foo.perl 22:59

TimToady line 109, that currently reads "$out = self.precomp-path,", probably needs to be "$out = self.precomp-path, ->" instead 23:00
timotimo wow. i just watched "Grindhouse: Planet Terror" with three friends. it was quite amazing 23:01
TimToady otherwise lines 110,111, and part of 112 are not in a sinature
*sig
timotimo and now the weekly blog post is going to be "a bit" late again
ugexe i see. ill give that a shot 23:02
tony-o timotimo: did you watch it intertwined with the tarantino part of the series? 23:08
TimToady m: $_ = 42; s/\d+/xxx/; .say 23:10
camelia rakudo-moar ae6863: OUTPUT«xxx␤»
timotimo tony-o: please be more precise?
tony-o timotimo: grindhouse has two movies, one by tarantino and one by rodriguez - when they played in the theaters the movies played in a way that a little bit played from one, switched to the other and played a bit there, until both were done 23:12
timotimo oh 23:13
i didn't know
we only watched the rodriguez part
but tarantino had a role in it again and it was also nice
and of course there were the "fake" previews for other videos
movies*
tony-o the other one is called death proof
they're both pretty good though ^^ 23:14
timotimo we're now watching Mystery Science Theater 3000 (the movie) 23:16
ugexe -> gave me X::Syntax::Malformed :( 23:26
gist.github.com/ugexe/471a878e3b85be9d2446
timotimo can you show more context? 23:27
ugexe as in, more of the build log? or the piece of code i changed
timotimo the resulting m-CORE.setting 23:29
close to the problematic line
lucasb method precomp(CompUnit:D: $out = self.precomp-path, :$INC = @*INC, :$force, --> Bool) { ... } 23:31
^^ The signature is this one, isn't it?
ugexe yes 23:32
except with the '->' added after $out = self.precomp-path
(updated the gist to include)
lucasb to me, it looks like a valid signature *without* the "->" 23:33
ugexe eh me too. timtoady thought it didnt look valid and suggested adding the '->' 23:34
timotimo a ->? 23:35
how can you have a -> without a { }
ugexe < TimToady> line 109, that currently reads "$out = self.precomp-path,", probably needs to be "$out = self.precomp-path, ->" instead 23:36
timotimo i'm a bit confused 23:37
well, --> needs to be inside the ( ... ), but why would it be -> instead? 23:38
ugexe --> *is* inside the ( ... )
timotimo where can i see the code? 23:39
more than just a few bytes?
ugexe gist.github.com/ugexe/c9222be48783...e1-txt-L29 23:41
timotimo i don't see a method precomp at all 23:42
ugexe CompUnit.precomp passes that :@INC to CREATE-INCLUDE-SPEC, but CREATE-INCLUDE-SPEC incorrectly returns true for nqp::istype($_,CompUnitRepo::Locally); and thus incorrectly calls .short-id on a Str (or IO::Path)
$cu.precomp line 29?
timotimo it's a use, not a declare
i have no idea what's even ... 23:43
ugexe its calling the .precomp method on a CompUnit object
timotimo i thought there was a syntax error? 23:44
ugexe oh i thought you meant the code that led to the discussion between me and timtoady 23:44
github.com/rakudo/rakudo/blob/2cd9...it.pm#L109 23:45
timotimo maybe i'm not in a state to make sense of the whole situation
ugexe all i did was add the '->' as suggested
