It's GCC. I expect it to behave oddly, and differently depending on version. :)

I don't know either. But these src tests are currently using embed.h and
they are embedding parrot, so it seemed natural to me, to include
Parrot_runt_native() in the embedding interface. This functions should
be a clean way to run a C function at the same level as its done from
the run loop level.
It's a good place for now. I'm not sure it's a good long-term place, 
but we'll worry about that later.

CVS checkout hints for the bandwidth-limited

2003-09-26 Thread Dan Sugalski
Just a reminder to everyone (especially now that we've updated ICU so 
there's  a lot of data to sync with) you can tell CVS to use a compressed 
channel for its data. For mostly-text (like, say, ICU's source) this works 
pretty well. Just add the -zN flag to the CVS line, where N is a number 
between 1 and 9. (Higher means more compression, though that takes more 
CPU tume)

For example, to update your local parrot version, just issue the command

  cvs -z9 update

and let the data stream on down. This'll cut down on the amount of data 
that's transmitted by rather a lot (factor of two or three, IIRC) so if 
you're on dialup or slow DSL it'll make your life much nicer.

[PATCH] C code test header

2003-09-26 Thread Michael Scott
Given Leo's new scheme for C code tests, I suggest that we add a header 
to be included in the test, and modify Parrot::Test so that it knows to 
add the header's location to the command.

This patch puts the header in parrot/t/c_test_header.h.

The correct scheme for a C test can now be:

c_output_is(<<'CODE', <<'OUTPUT', "C code test");
#include "c_test_header.h"
int do_test(Interp *interpreter)
{
...
}
CODE
...
OUTPUT


c_test_header.h
Description: application/applefile
#include 
#include "parrot/parrot.h"
#include "parrot/embed.h"

int do_test(Interp *interpreter);

int main(int argc, char* argv[]) {
Interp* interpreter;
interpreter = Parrot_new();

if ( interpreter == NULL ) return 1;
interpreter->lo_var_ptr = &interpreter;

Parrot_init(interpreter);
return do_test(interpreter);
}

Lightweight Languages 2003 Call for Presentations

2003-09-26 Thread Dan Sugalski
  Lightweight Languages Worshop 2003 (LL3)
  --
   
   Saturday, November 8, 2003, MIT, Cambridge, MA
   http://ll3.ai.mit.edu/   mailto:[EMAIL PROTECTED]
   
CALL FOR PRESENTATIONS

LL3 will be an intense, exciting, one-day forum bringing together the
best programming language implementors and researchers, from both
academia and industry, to exchange ideas and information, to challenge
one another, and to learn from one another.

The workshop series focuses on programming languages, tools, and
processes that are usable and useful.  Lightweight languages have been
an effective vehicle for introducing new features to mainstream
programmers.

We encourage presentations on topics of interest to the community of
lightweight language users and designers.  We prefer topics that will
interest a broad audience.  We do not require the presentation of
novel research ideas.

Proposal Abstracts
--
Due Friday Oct. 17

  We seek two to five page abstracts of talks to be given at the
  workshop.  Talks will be 30 minutes long, including time for
  questions and answers.  Presenters are not expected to submit
  papers, but slides will be published on the workshop web site.
  We will also consider proposals for talks of different lengths.

  Some suggested topics are:

* Language design: New language features, type systems and other
  reasoning tools, critiques of existing languages.

* Implementation techniques: Interpreters and virtual machines,
  optimizations, cross-language interactions.

* From scripts to programs: Software engineering with
  lightweight and/or a mix of languages.  How to (or not to!)
  scale from little scripts to large, complex applications.
  Application war stories.

* From ivory tower to cubicle -- what language implementors need
  to know from academic programming languages research -- and
  back.

* Lightweight pearls:  Elegant and instructive examples of
  programs in lightweight languages.

* Programming tools and development processes.

  Send submissions to: [EMAIL PROTECTED]

We want presentations that will inspire, motivate, and educate. We
want language implementors and researchers to leave the workshop fired
up with ideas for future languages, features, and implementation
tricks.  We want language users to leave the workshop fired up with
new ideas and new tools.

In addition to submitted presentations, there will be two invited
talks. After the workshop, there will be an evening social event and
dinner.

Dates:  Tuesday, Oct. 17 -- submissions due by end of day.
Tuesday, Oct. 24 -- notification of acceptance or rejection
Saturday, Nov. 8 -- 9am-7pm, LL3!  

Program Committee:

  Ken Anderson, BBN (co-chair)
  Jeremy Hylton, Python Software Foundation (co-chair)

We might need to shift to this scheme--whatever went in to fix the test 
caused it to fail on all the tinderboxes this morning. 

Tinders, for the curious, are at  
http://tinderbox.perl.org/tinderbox/bdshowbuild.cgi?tree=parrot and we've 
finally got a reasonably reliable mix of systems running the code. (Though 
I don't, as yet, have a native Windows w/VS/.NET building parrot right, 
just the cygwin version)

I have put now the test in its own sub. So it should be sure that
interpreter->lo_var_ptr (the stack limit for trace_system_stack) is
above the auto _hash variable.

Another possibility is to use the scheme I implemented in t/src/basic_3.
This needs some polishing thow - but it works :-)

Thanks. I admit I still have an urge towards a more compact 
notation--something like "set P[I4], P5"--but it's probably best to 
forbear. (Though I expect we'll end up wishing we did it differently 
later, in which case someone can write a Parrot macro assembler with a

Disabling empty cup collection - i.e. a big sign saying "Don't take my

big = calloc(BIGLEN, sizeof(char));
big = memset(big, 'x', BIGLEN - 1);

Wher does it fail?
Can you debug/back-trace it?

And just as I was going to get started on t/src/string.t too.
I'm running tests on string_compare and string_transcode with 999 
byte strings without complaint.



I've made it a bit smaller: 65536.

This begs the questions:

 What is the maximum hash key size?
 What is the largest STRING?
There are no limits except those imposed by UINTVAL (2^32-1) AFAIK.

Done.

I named it C though, to more clearly discern it from C.

.flatten_arg _AV_x is implemented too.

Checking for overflow in the sub needs still to be done.

Done.
