pmichaud | i.e., it's taking the list 2,3 and .... right | ||
ewilhelm | thanks. I'll kick some other tire for now | 00:57 | |
ruoso | ewilhelm, in case you're lacking tires... take a look at the wiki page I've just mentioned above ;) | 00:58 | |
ewilhelm | what's the best way to keep track of which hubcaps are expected to fall off? read the fudge? | ||
pmichaud | slices and slice context are two items that I have waaaaay down the list on the ROADMAP, and as taking a significant amount of time for me to develop. | ||
which means jonathan++ will probably do it in a couple of days :-) | |||
looking at the fudged tests is probably the best way, as well as perusing the RT queue | |||
we might be able to at least generate a warning that slice context isn't working yet, though. | 00:59 | ||
ruoso | pmichaud, that shouldn't be so hard since that is something that could be detected by syntax... | 01:03 | |

ruoso_ | pmurias, the RI's we have so far are not gc'ed because they will be needed in the entire life of the interpreter anyway... as well as the constant identifiers, native bool true and false and some other values... | 09:56 | |
pmurias, it's important to understand that we're going to have a limited number of RI's... | |||
all the code compiled by s1p will only use pre-defined RI's... specifically p6opaque, code, method etc | |||
so I don't think it's much of a problem that the RI's doesn't share much of the implementation... | |||
but nothing stops anyone from having a RI that is subject to gc | |||
it's just because it doesn't make much sense to have gc for such basic RIs | |||

moritz_ | s1n: no. I'm not online this weekend :( | 11:28 | |
s1n | okay, real fast | 11:29 | |
i talked to pm about those undef warnings that he turned on in the test suite | 11:30 | ||
i looked into it, most seem to be things marked todo, such as slices, that are not working, hence the undef warning | |||
i wanted to try and clean them up but i didn't want to turn a todo into a skip | |||
what do you think? | |||
moritz_ | I think the slices can be turned into skips | 11:31 | |
and I also think that we need a "no warnings" pragma, because some tests are valid as they are now | |||
s1n | i was thinking that too | ||
yes, pm and i have a plan for that | 11:32 | ||
moritz_ | stuff like my $x; $x++; is $x, 1, "\$x autovivifies' | ||
and we need a way to test if a warning was generated | |||
s1n | that we do | ||
moritz_ | how? | ||
s1n | no, i was agreeing | ||
moritz_ | ok | ||
s1n | i talked to pm about it and he said we could work on it once the undef warnings were handled | 11:33 | |
i'm going to work through those warnings this weekend and then get to the warning detection thing | 11:34 | ||
moritz_ | the first very basic step in terms of the test suite is to grep for thinks like 'is ..., undef' and replace them by 'ok !defined(...)' | ||
s1n | yeah i'm doing that now | ||
is !defined preferred over .defined? | |||
moritz_ | yes, because the latter doesn't work reliably in rakudo | 11:35 | |
or you can use ok $stuff ~~ undef, "description"; | |||
s1n | shall i replace the .defined with !defined? | ||
moritz_ | only if the tests brake | ||
s1n | alright | ||
that's what i needed to know | 11:36 | ||

r31033 | jonathan++ | [rakudo] Implementation of =<> that may work. Not completely sure it works, since we never manage to parse this operator yet. Checking it in now, so I don't do it as part of another commit of something else by accident at some point in the future; it'll work once parsing stuff | 17:17 | ||
..is fixed up. | |||
ruoso | pmurias, the idea is that the object can decide to implement whatever memory management it wants... | 17:21 | |

ruoso | so even forcing manually-managed RI's to register themselves in a central list is something I'd like to avoid... | 17:22 | |
pmurias | ruoso: i abandoned that idea and intend to have the RI's refcounted/traced | 17:43 | |
ruoso | pmurias, it is an important feature to support values that are not subject to gc | 17:44 | |
rakudo_svn | r31034 | jonathan++ | [rakudo] As we aren't smart enough in the compiler yet to sort between class/role types and subset types, do it upon construction of signature objects. This gets signature objects in shape for the multi-dispatcher. | ||
ruoso | I agree that some RIs might be gc'ed... but I'd like to avoid making that a requirement | ||
rakudo_svn | r31035 | coke++ | [rakudo] fix a doc typo. | 17:51 | |
pmurias | ruoso: it's not a requirement i just want the setting up/cleaning up RIs to be less of a magic process | 17:54 | |
ruoso | pmurias, in the last stage of the smop initialization, you can have objects being added to the global namespace | 17:55 | |
pmurias | setting the ref_cnt of a freed object to 999 is strange | ||
ruoso | pmurias, if you add the RI to the global namespace, and leave there the only reference, it will be freed when the global namespace is destroyed... | 17:57 | |
pmurias, that is just a hack to allow you call DESTROY during destruction | |||
pmurias, we could have a flag or something noticing that that value is already being destroyed... | 17:58 | ||
pmurias | i think it would make more sense to just set it to 1 | ||
ruoso | in practical terms, it's the same thing... | 17:59 | |
setting it to 999 only makes it very clear that the object is being destroyed when you're debugging it | |||
pmurias | and ref_cnt < 0 is a bug | ||
ruoso: that's a point ;) | |||
ruoso | pmurias, yes... that's why it tests for ref_cnt <= 0 (maybe it should simply be == 0, but I don't think it actually matters, since it can't get below 0 without being equal to 0 anyway | 18:00 | |

ruoso | pmurias, but anyway... I think we can start using more the global namespace... and that should make the initialization and destruction "less magical" | 18:04 | |
pmurias | ruoso: can i move SMOP_LOWLEVEL_INTERNAL into the header | ||
ruoso | pmurias, which header? | ||
pmurias | smop_lowlevel.h | ||
ruoso | yeah... I think so... we can consider objects that are implemented using the default lowlevel are part of a "community" | ||
pmurias | as i want to do a DESTROYALL less reference counting for the meta-ri | 18:05 | |
ruoso | but always keep in mind that smop_lowlevel.h refers to the *default* lowlevel implementation | ||

pmurias | ruoso: not to call DESTROYALL when RI's are freed, you can see look at release in smop_ri.c | 18:19 | |
ruoso | I see... you know that you could have the ri receiving the message itself, and discarding the message if the invocant is the ri.. but having a meta_ri is probably easier anyway | 18:23 | |
18:23
zamolxes joined
|
|||
pmurias | message being MESSAGE? | 18:25 | |
ruoso | yes... I mean... the RI is the RI of itself | 18:27 | |
so it does receive DESTROYALL call when it is itself being destroyed | |||
it's just a matter of not doing anything when the RI is in auto-destruction | 18:28 | ||
but maybe the meta-ri is a better solution anyway... | |||
pmurias | i don't call the DESTROYALL on the meta-RI because strange things happend when i used the generic_release | 18:30 | |
strange thing = two REFERENCES and then a RELEASE and no DESTROYALL | 18:31 | ||
ruoso | maybe because that destoyall was trying to manipulate the RI as if it were a instance that uses that RI... | 18:33 | |
and that would cause this kind of bug... | |||
but as I said... the meta-ri is probably a better idea... | 18:35 | ||

23:05
sri_work left
|
|||
TimToady | it parses all of the test suite. the main shortcoming of STD parsing (in the abstract) is that it doesn't know about POD yet except to skip it. | 23:08 | |
Limbic_Region | well, correctly skipping it in all of its edge cases is a good way to being able to parse it :-) | 23:09 | |
TimToady | the other issue is that it doesn't actually perform "use" yet, so it doesn't know if subs are imported | 23:11 | |
and its symbol table is naïvely global rather than lexically scoped | |||
Limbic_Region | so is that the part I read about not installing mini-grammars in a p6 review recently? | 23:12 | |
TimToady | er, I doubt it | ||
I don't know what that means, unless it's a ref to rakudo | |||
certainly STD uses its own minigrammars successfully | 23:13 | ||
I suppose I should work on making everything in ext/ parse as well | 23:16 | ||
Limbic_Region looks for comment that invoked the question | 23:18 | ||
use.perl.org/~chromatic/journal/37420 # "our of the six failing tests are the fact that it does not install new grammar rules for user-defined operators" | 23:19 | ||
lambdabot | Title: Journal of chromatic (983) | ||
Limbic_Region | s/our/four/ | ||
but now I understand why that doesn't have much to do with use | 23:20 | ||
and is also over a month old | |||
TimToady | yes, fixed that some time ago | ||
Limbic_Region | chromatic has been playing catch up | 23:21 | |
so the big hurdle used to be LTM. With that out of the way, how do the last two things you mentioned rank? | 23:22 | ||
TimToady | answer, almost everything in ext fails due to using either obsoletel module declaration syntax or obsolete pod syntax :) | 23:24 | |
Limbic_Region | but that is more of an impact to the staleness of the test suite rather than a hurdle in figuring out STD.pm | 23:25 | |
I had high hopes for the annotation project that attempted to keep the test suite tied to the synopses so that finding where they went stale was easier | 23:26 | ||
so you have said for a while now that the synopses are for the most part complete - it is mostly fine tuning now. Is that from the standpoint of the semantics of the language or is it really that complete? | 23:27 | ||
Specifically, S29 and things like pack/unpack as well as coroutines and the like | 23:28 | ||
oh, and in case you wondered - this isn't an interview :-) | |||
I just happen to have a free few minutes with the wife and kids upstairs | |||
TimToady | well, pack/unpack are far from core issues, and as for coroutines, those are less powerful than gather/take, so I don't know that p6 will even have coroutines officially | 23:29 | |
Limbic_Region | ok, let me ask my question a different way | 23:30 | |
TimToady | it's more important to figure out how various types will serialize themselves than in how to force it externally by pack/unpack | ||
perhaps a given type will be able to supply a pack template though | |||
you're asking about Christmas, aren't you? | 23:31 | ||
Limbic_Region | at one point, the synopses said "the same as p5 unless otherwise specified" but one of the goals of p6 is to have a specification independent of the implementation | ||
nope | |||
I am more wondering how close we are to someone being able to start making a run for a christmas | |||
TimToady | people are running for christmas all the time, as when they're not sure whether the p5 doctrine applies, they ask | 23:32 | |
(or not...) | |||
arguably some of parrot's issues historically have come from not asking... | |||
Limbic_Region | well, I am not looking at any implementation really | 23:33 | |
I have been very interested in what John M. Dlugosz has been working on | 23:34 | ||
TimToady | anyway, all I can tell is whether the process is converging or not, and I think it is. but as to how fast it's converging... | ||
I've been wondering whether it would be helpful to put the specs out under pugs/ so he can edit them. | |||
(and anyone else who wants to fill in the gaps) | 23:35 | ||
I feel like I'm a bit of a bottleneck on that part. | |||
Limbic_Region | Well, he had to go back to paying work recently and is restricted to weekends, but he still seems to be extremely productive | 23:36 | |
TimToady | hmm, it occurs to me that the server I'm using to run irssi from is in Houston... :/ | ||
Limbic_Region | and is finding things that make me think | ||
TimToady | or somewhere thereabouts, hopefully above sea level | ||
Limbic_Region | if we were to say - ok "done", go implement | ||
TimToady | no, that's waterfall chart thinking | 23:37 | |
we don't do that here | |||
Limbic_Region | we would end up with a whole bunch of unstated assumptions implemented a number of different ways | ||
TimToady | we do whirlpool design with feedback at every level all the time | ||
we're not smart enough to design everything in advance | 23:38 | ||
Limbic_Region | let me try again | ||
TimToady | and when everything finally converges there will be this big sucking sound in the middle :) | ||
Limbic_Region | not too long ago, the lists were rampant with questions about semantics | ||
syntax | |||
etc | |||
that seems to have dried up for the most part - at least from anyone not doing an implementation and just wondering | 23:39 | ||
Juerd | TimToady: Note that you can always use feather for irc if necessary | ||
Limbic_Region | and you have said yourself that things are mostly just fine tuning | ||
TimToady | after sacrificing to the latency goddess... | ||
Limbic_Region | so who else would know where the areas are that are still left to be specified | ||
and it seems like John is turning stuff up that no one else is | 23:40 | ||
TimToady | primarily the implementors | ||
and John... :) | |||
Limbic_Region | bah - I don't have a well formed question or concern | ||
other than to say it is hard to measure how far into the second 80% we are | |||
s/we/you/ | 23:41 | ||
TimToady | I thought you said you weren't asking about Christmas :P | ||
Juerd | TimToady: irssiproxy and a local client overcomes the terminal lag problem, though with huge setup overhead :) | ||
Limbic_Region | TimToady, no, I am asking when the Sears WishList Catalog is coming out - the precursor to Xmas | 23:42 | |

rakudo_svn | r31042 | jonathan++ | [rakudo] Constraints in a signature should actually be represented as an all Junction, not an array. | 23:42 | |
Limbic_Region | oh wow, apparently the Sears Wish Book catalog had gone extinct for 14 years but returned in 2007 | 23:43 | |
multichannelmerchant.com/news/sears..._10102007/ | |||
lambdabot | Title: Sears Wish Book Makes a Return | ||
Limbic_Region | I used to wait patiently every year for it to come and dream | 23:44 | |
rakudo_svn | r31043 | jonathan++ | [rakudo] The Perl6MultiSub PMC when checking constraints should do ACCEPTS on them, not just invoke them - it's meant to be a Junction. | 23:45 | |
Limbic_Region | oh, so here is a real question | ||
in perl 5, I recently wanted to write to the read only captures ($1 for instance) because I wanted to lie about what matched - can I do that in perl 6 and if so, how? | 23:46 | ||
TimToady | I don't think Match objects are readonly, so you'd just have to bind the new value in at the appropriate spot | 23:47 | |
rakudo_svn | r31044 | jonathan++ | [rakudo] While we likely need a real Exception class at some point, we should map them now so .WHAT etc works on $! after a failed try. | ||
TimToady | after all, the match itself is scribbling on the Match object all the time | ||
Limbic_Region | >:-) lies, damned lies, and Match objects | 23:48 | |
TimToady | but it would have to be a binding, since assignment to $1 is reserved for modifying the original string | ||
assuming we ever implement :rw | 23:49 | ||
it might not be possible to define it consistently | |||
but anyway, bind bypasses all that, as long as $1 represents a real location somewhere | 23:50 | ||
(which it doesn't in Perl 5, hence the problem) | 23:51 | ||

TimToady | jonathan is a real workhorse. I'm trying not to think about the fact that my wife just checked Animal Farm out of the library... | 23:52 | |
gives new meaning to the term "glue language" though... | 23:53 | ||
Limbic_Region | I recently re-read 1984 but I haven't read Animal Farm since middle school | 23:54 | |
TimToady | I've never read 1984. I guess some books are more equal than others. :) | ||
Limbic_Region | heh | 23:56 | |

Limbic_Region | I also recently re-read Flowers For Algernon or so I thought | 23:56 | |
rakudo_svn | r31045 | jonathan++ | [rakudo] If we are calling ACCEPTS in a multi-dispatch to do a type-check, then because blocks are not differentiated from regexes at the moment we get exceptions when trying to store $/. This patch wraps that code up in a handler. | ||
Limbic_Region | I didn't realize there were two versions - one shorter and more appropriate for school age children | ||
and one more adult | |||
TimToady | yes, it was originally a short story, I think | 23:57 | |
and I think the short one is probably more better | 23:58 | ||
at least, that's what Glo tells me | |||
Limbic_Region is currently reading "The Female Brain" with "Do You Think What You Think You Think" on deck | |||
TimToady | well, duh, nobody thinks what I think I think, not even me... |
