parrot.org/ - clean up those smolders for the release!
Set by moderator on 20 October 2008.
particle you may be able to modify it not to use rakudo components 00:00
allison The exception "Parameter type check failed" comes from Rakudo 00:06
ruoso I guess that the MMD in Rakudo is failing because it is not considering that the multi must check variants outside itself before dispatching 00:07
this is similar to the problem of lexically-declared sub variants

ruoso davidfetter, boa noite ;) 00:09

ruoso :P
allison, speaking of MMD... how do you plan to solve the issue of lexically-declared multi variants? 00:13
allison what problem? ticket #? 00:14
ruoso it's more of a conceptual problem
allison how so?
mmd subs are just subs
ruoso right... but then you have a new variant lexically declared in an inner scope... 00:15
allison aye, and inner scopes take priority over globals 00:16
ruoso but then the inner version needs to find the outer declarations...
allison the semantics of the interactions between lexicals and globals differs from one HLL to the next 00:17
ruoso right... so let's consider only lexicals
allison Parrot doesn't have lexical MMD at the core
only global MMD 00:18
ruoso hmm... ok...
allison so, if Rakudo does lexical MMD, then we need to know what semantics they're trying to support
there's a good chance they can do it without any core Parrot changes, since Rakudo has its own MultiSub PMC
ruoso in one line: { my multi foo (Int $a) {...}; { my multi foo (Str $a) {...}; <you can see foo(Str) here> }; <but not here> } 00:19
allison but, if they need some hooks added to core Parrot to make it simpler, we can certainly add them
so, Rakudo's MultiSub needs to check the lexical scope for MMD variants before checking the global namespace 00:20
ruoso ok... that's also how I plan to do... 00:21
it's good to know I'm choosing a sane path ;)
allison it's up to the HLL to decide if lexical MMD's should always have priority over global MMDs (so, a lexical MMD means the global is ignored), or should just be added as another alternate compared in the total collection of MMD variants
ruoso hmm... actually lexical does not hide global in Perl 6... but I think it doesn't make much difference... 00:22
allison either way works, it's just a slight change in the search order 00:23

Coke down to 3330 lines of tcl to cause the segfault. :| 01:36
cotto I guess that's progress. 01:37
Coke bah. 01:48
01:53 Andy joined
Coke where do constant strings get created? 02:01
hurm. const STRING * is probably not the same as a CONST_STRING, izzit. 02:02
Infinoid nope, CONST_STRING is a function that calls string_make_direct 02:04
Coke maybe I can use the trick from www.oreillynet.com/onlamp/blog/2007..._in_p.html against string_make_direct instead of pmc_new 02:08
but not now; if anyone's bored (ha), it's reproducable on feather with latest parrot and partcl, with "../../parrot tcl.pbc t_tcl/namespace-old.test" (hve to run make spectest first to get the .test file) 02:09
