Perl 6 Summary for 2006-01-02 though 2006-01-09
All~
Welcome to another Perl 6 Summary. On a complete tangent, if you are
playing World of Warcraft and see a troll hunter named Krynna, she
rocks. She royally saved me. Be nice to her.
Perl 6 Compiler
PIL Containers and Roles
Audrey explained that she and Stevan have been putting in effort to
allow Pugs and PIL to bootstrap Roles and eventually the entire object
model.
<http://xrl.us/jiza>
Reference and Assignment Semantics
Audrey posted a brain dump focusing on the issues and implications of
how containers, assignment, and auto dereferencing interact.
<http://xrl.us/jizb>
Table of Perl 6 "Types"
Stevan Little posted a summary of his understanding of Perl 6's core
type hierarchy. Larry replied with a few comments and corrections.
<http://xrl.us/jizc>
Parrot
Configure and Symlinks
Alberto Simoes wondered how the configuration system should handle
symlinks. Warnock applies.
<http://xrl.us/jizd>
Removed NCI Types
Dan Sugalski wondered why the T and L parameters have been removed from
NCI and how he should work around their absence. Leo suggested you
ManagedStruct PMCs for it and pointed him to the SDL libraries.
<http://xrl.us/jize>
" mkdir " test can fail
Bob rogers posted a patch fixing an unanchored regular expression in the
mkdir test. Warnock applies.
<http://xrl.us/jizf>
Build html should use Pod::Find
Joshua Isom suggested that Pod::Find would make building html less error
prone and more robust to changes the Pod structure. Warnock applies.
<http://xrl.us/jizg>
CWD on HP-UX
Nick Glencross posted a fix to os.pmc for HP-UX. Alberto Simões applied
the patch.
<http://xrl.us/jizh>
Alignment Issues on HP-UX
Nick Glencross posted a back trace from a test failing on HP_UX. His
initial analysis indicates that it is an alignment issue. Warnock
applies.
<http://xrl.us/jizi>
Tcl Todo
Will Coleda posted more todos for Tcl. Like last week, I won't summarize
them all. But I am very happy to see Tcl coming along again. I must say
that I always like watching the test percentages climb.
Parrot 0.4.1
Leo announced the release of Parrot 0.4.1.
Sun's Compiler No Like CRLF
Andy Dougherty noticed that Sun's compiler was choking on coroutine.pmc
because it had bad line endings. He fixed it, and Jerry Gay applied the
patch.
<http://xrl.us/jizj>
atan2 issues
Joshua Hoblitt committed a possible fix for some atan2 issues occuring
on openbsd, solaris, and cygwin. The fix didn't help cygwin or solaris.
No word on openbsd.
<http://xrl.us/jizk>
OS.pmc needs a few methods
Will Coleda created a few todo: OS.pmc needs an lstat method, and
methods to set atime and mtime.
<http://xrl.us/jizm>
<http://xrl.us/jizn>
Vanishing Warnings
Will Coleda noticed that a few warnings disappeared. Leo admitted that
he accidentally applied a fix some time ago.
<http://xrl.us/jizo>
Configure.pl and Optimize
Andy Dougherty noticed that Configure.pl --optimize no longer worked
correctly. Joshua Hoblitt took the opportunity to clean up that portion
of Configure.pl.
<http://xrl.us/jizp>
Event System Question
Klaas-Jan Stol wondered why events (unlike exceptions) are handled after
a little time instead of immediately. Leo explained that this was due to
the asynchronous nature of an events arrival and the inability to resume
execution after a long jump.
<http://xrl.us/jizq>
CFLAGS missed two files
Andy Dougherty noticed that the core_ops source files missed come of the
directory rearrangements. Jerry Gay applied the patch.
<http://xrl.us/jizr>
File::Temp Issue
Leo noticed an issue in t/run/options. Jerry tracked it down to an old
version of Perl and the File::Temp module and fixed the problem.
<http://xrl.us/jizs>
Simple Namespace Question
Joshua Isom wondered how to separate namespaces for find_global calls.
Leo explain that he should use a list like ['Foo'; 'Bar'].
<http://xrl.us/jizt>
Credits
The ever modest Nick Glencross updated his name in the credits file to
be a little more understated. Oddly, no one applied the patch.
<http://xrl.us/jizu>
parrot config revisited
Nick Glencross posted a few questions, thoughts, and patches involving
parrot_get_config. Leo agreed with most of it, but had a few comments.
<http://xrl.us/jizv>
pkgsrc build
Anders Nor Berle provided a few patches making thing work a little more
smoothly with FreeBSD and pkgsrc. Jerry Gay reviewed the patches and
Florian Ragwitz applied the relevant portions. In fact, 0.4.1 got added
to pkgsrc for the curious.
<http://xrl.us/jizw>
<http://xrl.us/jizx> -- 0.4.1 added
static and shared libparrot
Florian Ragwitz provided a patch that fixed the issue with building both
a shared and static libparrot. Nick Glencross applied the patch. Nick
Glencross made OS X and HP-UX build shared parrots. Anders Nor Berle
helped FreeBSD along. Jonathan Worthington brought MSVC into line. Nick
Glencross also finished up the painful task of making it all work on
Cygwin.
<http://xrl.us/jizy>
<http://xrl.us/jizz>
<http://xrl.us/jiz2>
<http://xrl.us/jiz3>
<http://xrl.us/jiz4>
<http://xrl.us/jiz5>
GC Bug with String Ops
Roger Browne was tracking a GC Bug involving string operations.
Unfortunately, no one else could reproduce it. Doubtless, we will see it
again.
<http://xrl.us/jiz6>
Winter Cleaning
Jerry Gay, not content with his fall clean up, has done a winter clean
up too. This time he went through and cleaned all the svn metadata.
<http://xrl.us/jiz7>
Paper on Parrot
Klaas-Jan Stol posted a link to his paper on Parrot. It is not yet
finished and, like most things documenting parrot, already out-of-date,
but it can probably serve as a good introduction.
<http://xrl.us/jiz8>
<http://xrl.us/jiz9> -- The Paper
<http://xrl.us/ji2a>
string_to_int issues
Roger Browne found and tried to fix a problem with string_to_int.
Unfortunately Leo beat him to the fix. Fortunately, Roger found a fixed
another problem with it.
<http://xrl.us/ji2b>
<http://xrl.us/ji2c>
Parrot for Windows Macros
Christian Lott wondered how hard it would be to write inter application
macros in Parrot. Unfortunately, his wonderings didn't seem to make it
to the list. Warnock applies.
<http://xrl.us/ji2d>
Installation of Include Files
Anders Nor Berle provided a patch which fixed parrot's installation of
include files. Warnock applies.
<http://xrl.us/ji2e>
Parrot on Cygwin
Alberto Simões wondered if he was doing something wrong while trying to
get parrot to build on cygwin. Nick Glencross answered that it didn't
work yet, but he was on the job.
<http://xrl.us/ji2f>
Clearing Exceptions Only in the Current Context
Bob Rogers provided a patch which makes clear_eh only clear exception
handlers in the current context. Warnock applies.
<http://xrl.us/ji2g>
Update Patch Instructions
Roger Browne posted a patch updating submissions.pod. Joshua Hoblitt
applied and improved upon Roger's patch.
<http://xrl.us/ji2h>
File Copy
Will Coleda opened a can of worms when he asked for a copy file method
on os.pmc. Chip had some good insights.
<http://xrl.us/ji2i>
doc/ops Permission Issue
Joshua Isom posted a patch fixing some permissions issues with installed
parrot docs. Warnock applies.
<http://xrl.us/ji2j>
Smoke that Cross Site Scripting
Joshua Hoblitt noticed that the smoke system was not very health
conscious about its input. Florian Ragwitz said that he was about to do
a rewrite to fix the issue.
<http://xrl.us/ji2k>
Patches Go to parrotbug
Joshua Hoblitt noticed that not all patches were making it into RT. So
he posted a friendly reminder that everyone should submit patches
through parrotbug.
<http://xrl.us/ji2m>
TODO: make distcheck
Joshua Hoblitt created a TOD for distcheck.
<http://xrl.us/ji2n>
META.yml Needed
Joshua Hoblitt also suggested that we generate a META.yml so CPAN can
index it.
<http://xrl.us/ji2o>
Muddle Cleanup
Bernhard Schmalhofer resurrected an old ticket when he posted his
thoughts on how far our documentation muddle had progressed. Original
ticket from Sep 2004.
<http://xrl.us/ji2p>
optimize pmc2c.pl
Joshua Hoblitt noticed that pmc2c.pl could be fairly easily optimized.
Any up for some low hanging fruit?
<http://xrl.us/ji2q>
Dynamic Binding
Bob Rogers posted an RFC about dynamic binding. Leo and Steve Gunnell
both provided comments.
<http://xrl.us/ji2r>
svk-bootstrap-dump
Joshua Hoblitt noticed that svk's bootstrap dump was a little old. We
should probably automatically generate updated one for the SVK loving
world.
<http://xrl.us/ji2s>
Dyn Op Build Process
Jonathan Worthington committed some changes rationalizing and improving
the dynops build process. Nick Glencross affirmed that it worked on
cygwin.
<http://xrl.us/ji2t>
COWs Eat Memory
Leo found an interesting example. By reversing a string in place using
substr he can make Parrot consume memory like never before. This was
causing a panic, which he fixed. But the core issue remains.
<http://xrl.us/ji2u>
Bug Wranglers
Joshua Hoblitt posted a start to a bug wrangler document. Jerry Gay
encouraged him to check it in.
<http://xrl.us/ji2v>
Funny EDS Commercial - Cat Herding - Google Video <http://xrl.us/ji2w>
Lua2PIR Translator
Klaas-Jan Stol posted an update to his Lua2PIR translator.
<http://xrl.us/ji2x>
Perl 6 Language
Environmental Variables
Luke Palmer suggested that $/ and $! should be made into environmental
variables. Thomas Sandlass like the idea.
<http://xrl.us/ji2y>
Implementing Several Signatures
Jonathan Lang wondered if there where a concise way to implement several
function signatures at once. Fayland Lam pointed out the is commutative
trait, but Miroslav Silovic warned that that actually generated another
function which transposed the arguments.
<http://xrl.us/ji2z>
Zip vs Each
Jonathan Lang noticed that S4 and S3 did not agree on the usage of zip.
Larry clarified that S4 was out of date.
<http://xrl.us/ji22>
Junctions Again
Once more the perennial argument has returned. Junctions will either
cure cancer, kill babies, or both. Odds are they won't change this time.
<http://xrl.us/ji23>
Friendly Facades
Gaal Yahas wondered how to make "friendly facades" like use_ok. Yuval
Kogman suggested making it a macro, and Luke Palmer suggested a powerful
scope object.
<http://xrl.us/ji24>
Class vs Object Contradiction
Stevan Little posted a possible contradiction he saw from S12. Warnock
applies.
Representation Types
Stevan Little wondered how to handle representation types other that
P6opaque. Warnock applies.
