dlocaus pmurias: I'm currently trying to debug t/kp6/15-capture-from-rule-block.t 15:39
pmurias: the problem is I'm caught up in all of Pair.pm's INIT blocks, and it has a LOT of them. 15:40
15:40 amnesiac joined
dlocaus does anyone know how to force the debugger to skip the INIT { } blocks? 15:40
putting $DB::single and then using "c" doesn't work, the perl debugger still stops on the first line of INIT{ .. }
pmurias dlocaus: did fixing what i mentioned help? 15:43
dlocaus well, yes, it appeared to fix the majority of bugs, but 15-capture...t seams to go into an infinite loop
I think, I'm trying to figure out how to get the debugger to debug it.
pmurias you could temporarly disable INIT blocks in the emitter
dlocaus the INIT blocks are being invoked in Pair.pm 15:44
ha ah! 15:45
15:45 Psyche^ joined
pmurias dlocaus: fixed it? 15:45
dlocaus the solution is to create BEGIN { sub daniel_test { print 1; } }; then put main::daniel_test(); where you want the break point, and then use b main::daniel_test to get there. 15:46
pmurias: no, just finally got a break point :)
now, I'm going to try and find out where it infinitely loops (I'm assuming that 4 minutes of no response is an infinite loop.. rather than actuall slowness) 15:47
omg... 15:56
$::MyGrammar dumps to 3k lines of variable content.

dlocaus pmurias: ping? 16:24
With the fix you suggested, gammar tests 15 & 17 do not respond, but other tests do. Should I commit the fix, and then skip those tests? 16:25
by "do not respond" I mean they just continue running and there does not seam to be any resolution on the test.
pmurias dlocaus: pong 16:27
dlocaus do you have a suggestion?
pmurias dlocaus: commit the fix
dlocaus what about the test cases? 16:28
pmurias leave them as failures
16:28 justatheory joined
dlocaus they don't fail 16:28
they just keep on going...
as if they were in an infiniate loop
If I commit this, then some smoke server may be waiting a long time... 16:29
for results.
pmurias there isn't a smoke server for kp6 as far as i know
dlocaus should I deliberately break the 15 & 17 tests?, so that they "do" finish, with a failure at least?
pmurias hard question 16:30
dlocaus I know...
which, is why I'm asking :)
pmurias leave them as they are
the person debugging will not have to unbreak them 16:31
dlocaus how will people do the test cases to test their own changes, do the test cases?
everyone working on something else will be stuck.
pmurias break them then 16:32
dlocaus ok
pmurias i remembered that C-c stops the whole test process
have you used KP6_TOKEN_DEBUGGER=1? 16:34

r18776 | dlo++ | I have commited a fix on pmurias's suggestion, which appears to fix a has_default.bit() issue, where
r18776 | dlo++ | has_default was not being assigned a "bit" class. It was being left "undef", which caused a but in
r18776 | dlo++ | Emit/Perl5.pm which is depending on the has_default.bit class.
r18776 | dlo++ |
r18776 | dlo++ | I have deliberately broken grammar tests 17 and 15. With this bug fix, the test cases do not appear to complete.
r18776 | dlo++ | They either "hang" or go into an infinite loop. Test case grammar/15 does not complete after 4 minutes.
r18776 | dlo++ |
r18776 | dlo++ | Both test cases, have compiliation errors that will cause them to failure. Comments are included as to why they are
r18776 | dlo++ | forced to fail.

dlocaus pmurias: ok, I'll check that out 20:08
pugs_svn r18778 | dlo++ | [kp6] 20:13
r18778 | dlo++ | I have been really hard time chasing down a regex bug. Mostly due to the problem of tracing the stack. I have
r18778 | dlo++ | written code into Runtime/Perl5/MOP.pm ::DISPATCH to detect infinite loops. The premise is simple. If you see the
r18778 | dlo++ | same ::DISPATCH(ARGS) call more than once, you've entered a circular loop.
r18778 | dlo++ |
r18778 | dlo++ | This code is enabled by setting enviromental variable DEBUG = 1 (or 2 for more info)
r18778 | dlo++ | setenv DEBUG 1

dlocaus pmurias: I think MOP.pm needs to document the hash structures it builds. 20:18
pmurias: do you have any thoughts right off hand?
pmurias looking
dlocaus: it could document the internal object format 20:19
what fields besides _dispatch the object can have 20:20
dlocaus well, I was thinking that DISPATCH($::PROTO,'add_method','func', args ) could include $self->{_document} = [ 20:21
"func belongs to $self->{ name }", .. next func ];
putting _document in the list, would give the human debugger an idea of exactly where he is, when he's busy touring the list. 20:22
pmurias i don't understand
the objects need to keep extra info to make the dumps more readable? 20:24
dlocaus well, I was attempting to understand $::MyGrammar, and x \$::MyGrammar drops 3k lines of "variable settings". When I use the DEBUG code in MOP.pm (I just added it), it produces a trail 4k lines long.
20:24 idiotmax joined
dlocaus When we are going though the ::DISPATCH / $::MyGrammar, we need some way of "knowing" or having an "idea" of where we are. 20:24
pmurias grabbing a better chair& 20:25
dlocaus pmurias: ::DISPATCH( $::MyGrammar, 'tok2', );
that code generated 4k of enter/exit documentation
pmurias you shouldn't dump objects with Data::Dumper 20:26
dlocaus that wasn't Data::Dumper, that was perl's debugger x command 20:27
pmurias i'm not familiar with the perl debugger but i guess it's equivalent 20:28

dlocaus well, my point is I'm wandering in the forest of $::MyGrammar without a road map. 20:29

dlocaus is this something I should leave to fglock or someone else to debug? I'm getting a sense I'm starting to thrash. 20:45
pmurias it's not important
dlocaus ok. 20:46
I'm moving on to the next bug. I'll add this to the TODO list?
pmurias perl5rx is the engine which will be used for the bootstap
add it
dlocaus ok
is there a place where I can store code in the repositry in a kind of "my space" that other people can access? 20:47
like a home directory? I have a nice piece of code that I broke down, that would be useful to the next person who has to debug this.
