[Coke] I have a MS account if someone wants to invite me to dev.azure.com/Raku 13:44
trying to track down the cro abort trap. build a debug-enabled MoarVM. if I try to attach after I fire off the cro command, I get a gdb error, type "continue", then when cro aborts, gdb shows "exited normally". if I try to run cro through perl6-gdb-m, It seems to just hang. 13:57
Any other suggestions on how to debug? (on OS X)
lizmat: are you able to use cro on OS X? 14:00
timotimo on linux i'd say "run execsnoop against it to see which one is the one that borks" but that's ... linux
lizmat [Coke]: yes, well, it's been a while, but a $project I worked on used Cro, and it worked fine on my MBP 14:01
[Coke] can you try an updated rakudo/cro and do a 'cro stub app app' at some point? I assume it's just me, but... 14:03
I used it many moons ago, also
lizmat [Coke]: will try 14:05

[Coke] figured I'd do a spectest in this rakudo to see if I get the same issue on something smaller than cro. it tells me inline:p5 isn't installed, tests won't be run. run the command it gives me. rerun spec test. still tells me I:P5 isn't installed. 14:26

nine No joy trying to reproduce my BEGIN time EVAL issue in a reduced test case so far but....it's not that difficult to provoke other errors 15:23
Ooooh....it's not even a different issue after all. The "chars requires a concrete string, but got null" just happens when trying to report the "missing static code ref for closure" 15:26
MasterDuke ha 15:30
nine So, it really looks like a nested compilation at BEGIN time makes us lose static code refs for closures of the outer compilation unit
Shortest golf now: use NativeCall; sub abort() is native(Str) { !!! }; BEGIN EVAL ''; 15:33
Precompile that and: Serialization Error: missing static code ref for closure 'abort' (:1)
[Coke] the rebuild has no impact on my cro error. 15:34
also no impact on my zef/inline p5 issue. make spectest says it's not installed. zef says it is. 15:35

nine Huh...maybe it's not so much that the outer compilation unit is losing a static code ref for a closure and more like somehow the BEGIN time EVAL is causing it to need one where it wouldn't otherwise. 18:36
[Coke] nine: is that on my bug?
nine Dumping the QAST in compile_in_context gives the surprising result of the BEGIN time EVAL somehow causing the complete outer unit to be called in compile_in_context 18:37

Add IO::Handle.do-not-close-automatically and some reorganization

  - Add .do-not-close-automatically method
   This marks the IO::Handle not being closed by Raku automatically
   either by having DESTROY called on it, or on process exit.
   Returns a Bool indicating success of marking.
  - Add !close method
   This now handles all logic around closing of an IO::Handle, which
   centralizes some logic that was spread around before.
  - Rewrite some internal methods to be more readable
  - Add non-MoarVM versions of do-not-close-automatically and !close

nine I think, I'm hot on the trail... 20:49
I managed to get a full backtrace of the superfluous call to the outer unit and it seems to originate at github.com/rakudo/rakudo/blob/mast....nqp#L1298 20:51
lizmat intrigiung 20:53
nine Looks like $*UNIT is the outer unit there, not the EVAL's
lizmat doesn't EVAL set its own $*UNIT ? 20:54
nine It's set in the grammar in token comp_unit
lizmat m: slurp "ten","twenty" 20:55
camelia Too many positionals passed; expected 1 argument but got 2
in block <unit> at <tmp> line 1
lizmat so I want to change this to make it a compile time error
but this causes a test failure because there is some issue with the candidates 20:56
but I'm not seeing it
nine Oooooh! 20:58
Of course!
Thing is, $*UNIT is declared in the grammar. It starts to parse. It encounters the BEGIN block. The BEGIN block does an EVAL which fires up another compiler which writes to $*UNIT, so when the outer compiler's comp_unit action gets called, there's already a value there 21:00
But wait...the inner compiler declares its own $*UNIT, so it shouldn't touch the outer
lizmat it's really a "my $*UNIT" ? 21:01
nine And it's the inner compiler's comp_unit action that sees the outer's $*UNIT and calls it. Why doesn't it see its own instead?
:my $*UNIT;
lizmat caching ?
or maybe :my $*UNIT is lexical in the wrong scope ? 21:02
nine Even declaring it in EVAL itself doesn't make a difference. I'd guess that someone re-sets it somewhere, but I can't find anything like that. 21:11
Anyway, I think that's very decent progress already for today. More tomorrow :)

Tighten up sub slurp / spurt signature

Basically make 'slurp "foo", "bar"' a compile time error, rather than a runtime error.
Sadly, this creates a problem in the proto-arity-count check, of which I have no idea how to fix it. So exclude "slurp" and "spurt" for now from those tests. Fixes welcome!
