Now 5.8.8 is closer and porters give the final touches and wait on smoke signs. Issues in blead are being worked out, preparing for 5.9.3 as well.
Configure
Fix H. Merijn Brand applied one between two candidate patches by Yitzchak Scott-Thoennes to fix Configure on Cygwin.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00459.html
threads::shared
The last summary mentioned how Dave Mitchell's work on threads and shared variables improved speed while also closing RT ticket #37946. Nicholas Clark suggested the changes were packaged into a CPAN module, allowing people to try it without the need to hastily release the changes with 5.8.8.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00388.html
warn
Nicholas Clark did (in change #26787)
a refactoring on S_vdie_common
so that Perl_vwarn
can use it too.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00496.html
About ticket #38133 on a bug with quantified groups, Hugo van der Sanden layed out the process to fix a bug in the scary regex engine, followed by the conclusion that it must be a while until someone skilled find the time to initiate the process.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00336.html
In response to Jim Cromie reposting the patch to unify all arenas, Nicholas Clark suggested to wait until after 5.9.3 but Rafael Garcia-Suarez has the ultimate word.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00395.html
For perl593delta review, Nicholas Clark reminded the Sadahiro
Tomoyuki's XS-assisted swashget
and Steve Hay followed
with a list of the stuff he was involved in.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00520.html
Yitzchak Scott-Thoennes made a little change to t/TEST to get rid of some 'FAILED--unexpected ouput'.
relaxing TEST restrictions http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00344.html
Gisle Aas, Rafael Garcia-Suarez, Yitzchak and Jim Cromie went on discussing how to identify compiled snapshots versus releases.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00370.html
Jarkko Hietaniemi posted a patch to silence some format warnings in blead seen in Tru64 and due to certain assumptions about types and appropriate formats. Gisle Aas and Robin Barker had some comments about it.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00277.html
Philip M. Gollucci wrote to say building mod_perl 2 against blead on FreeBSD does not work since August. Prodded by Stas Bekman, Philip produced a small program to reproduce the issue, which Stas thought Philip could reduce even more using his familiarity with mod_perl code.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00288.html
Philip M. Gollucci forwarded a workaround to build MP2 on alpha platform from the modperl dev list.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00334.html
Pod::Simple
Allison Randal called for a diff of all the changes
that made into the core version of Pod::Simple
and this week she sync'ed the CPAN version, reaching release 3.04.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00461.html
open
and IO Layers Answering ticket #38181, Sadahiro Tomoyuki noticed
the issue with default IO layers ignored in 3-argument open
calls was recently resolved in blead and sent a
patch to assure the -C
switch was mentioned
in related docs.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00302.html
Jim Cromie added a few more lines to improve info about embed.fnc in pod/perlguts.pod. Applied as change #26756.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00313.html
POSIX
vs Fcntl
Andreas Koenig reported what he thought to
be unexpected warnings when requiring Expect.pm.
Nicholas Clark answered that the "redefined"
warnings were correct, as constant subroutines
were redefined indeed. But it was not due to
Expect
but rather to POSIX
and Fcntl
exporting
subroutines with the same name.
Nicholas proposed a patch so that POSIX
use Fcntl
to get the common values. Rafael Garcia-Suarez thought
it looked good as it ended an error that puzzled many
developers, even though it adds to POSIX
a dependency,
which appears to be harmless.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00326.html
Abe Timmerman brought the results of tests againts maint@26746 on VMS, which succeeds in 98.79% of test scripts.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00327.html
require IO
Dave Mitchell commented on ticket #37076 about
segfaults by mixing threads and require IO
.
The guilty part is newCONSTSUB()
which isn't threadsafe.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00329.html
Glancing at tickets #37488 and #37491 about bugs in perlcc, Dave Mitchel advised that this is no longer actively maintained, which means bugs are unlikely to be fixed.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00330.html http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00331.html
select
Bitmasks Nicholas Clark confirmed the patch by Gisle Aas
to allow ""
as select bitmasks is in perl-5.8.8.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00347.html
Jim Cromie noticed a failure to locate Digest/SHA.pm
after resync'ing, which suggested problems in change 26704
which added SHA-256 support for CPAN. It turned out
to be fixed by running Configure again, but Yitzchak
Scott-Thoennes reminded new extensions need to be manually
added to the win32 makefiles for distclean
to work right.
Rafael Garcia-Suarez committed change #26758 to solve this
case.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00351.html
Compress::Zlib
Paul Marquess brought in a major patch of Compresss::Zlib
against blead, with the previosly announced rewrite
to support other compression formats. Porters agreed that,
as 5.9.3 will wait until 5.8.8 and blead issues are worked out,
C::Z
would probably get enough days of smoke.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00377.html
Nicholas Clark did a lot more patch integration stuff and made a maint
snapshot perl@26746
.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00380.html
POPSTACK
Jan Dubois noted the little bit about POPSTACK
in perlhack.pod is wrong and called for someone
qualified to write a description about the "stack of stacks"
concept.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00382.html
Sys::Syslog
0.12 and 0.13 After Sébastien Aperghis-Tramoni announced Sys::Sylog
reached release 0.12, Alan Burlison noticed it was broken on
Solaris and other platforms. Alan, Rafael Garcia-Suarez,
Nicholas Clark and Gisle Aas investigated and patched
the issues. Sébastien merged the changes back to CPAN version
and released 0.13
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00261.html
As a compliment to his daughter's purple Barbie bus, Andy Lester coined a name for his last patch on his continued effort to improve code with regard to correctness and cleanliness.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00386.html
Andy also inquired why this kind of code is used throughout
if (ckWARN(WARN_MISC)) Perl_warner(aTHX_ packWARN(WARN_MISC), WARNING_MESSAGE);
instead of something like
Perl_warn_maybe( aTHX_ WARN_MISC, WARNING_MESSAGE );
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00471.html
setlocale(LC_ALL,"")
? Andrew Dunstan opened RT ticket #38193 to tell how
an embedded perl interpreter always starts by calling
setlocale(LC_ALL,"")
. But that's not an all-satisfying
solution for every application and he called for a way
to give more flexibility to avoid unintented effects
on character data.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00389.html
$0
Assignment when Embedding Gisle Aas noticed that, when embedding perl, the default
behaviour of $0
assignments writing to the memory of
argv[0]
and calling setproctitle()
is hardly the
expected action. It can cause segfaults and hide the
host application from ps for example. Gisle posted
a patch to allow disabling such behavior and is still
waiting for comments.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00391.html
Dave Mitchell pointed consting work waiting to be done is
changing C?OP*
usage to const C?OP*
, to prevent
code which messes with the fields of an OP. OPs are shared
between threads which makes a bad idea to fuss around
with them.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00398.html
H. Merijn Brand spent some time preparing a rx1620 dual Itanium to see what Perl builds are looking like in such architecture. Merijn discovered that, to use HP C-ANSI-C compiler, one needs to drop optimizing to -O1 for a range of this compiler family on HP-UX 11.23. All tests passed on both perl-5.8.x-dor:26763 and perl-current:26768, 32 and 64bit, but not threads. Next step is smokes on this box.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00412.html
Yves Orton wanted to know how to get access to code refs
embedded in regexes, so he could teach Data::Dump::Streamer
to dump them out correctly. Dave Mitchell revealed coderefs
in regexes are some sort of abomination more like evals
than proper closures. There is a plan to get them right, but not yet.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00423.html
version
0.53 John Peacock uploaded version
0.53 to CPAN and brought
the corresponding patch to bleed.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00439.html
Dominic Dunlop found that the release of Mac OS X 10.4.4 still has broken Catalan locales, which defeated the optimistical assumption that the problem would be fixed by now, and posted a patch to skip the bad locales once again.
Bad locales in Sep 2005 http://dev.perl.org/perl5/list-summaries/2005/20050915.html#OS_X_10.4_Issues Bad locales in Nov 2005 http://dev.perl.org/perl5/list-summaries/2005/20051107.html#Bad_Locales_in_Mac_OS_X Bad locales enter 2006 http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00452.html
:crlf
Xavier Noria noticed the :crlf
layer in PerlIO was not
portable as suggested in its documentation when it comes
to support Mac text files conventions and proposed a patch
to fix this (applied as change 26796).
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00462.html
On bug #38205, erik noticed a typo at perlfaq8, promptly patched as change #26802 in blead.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00467.html
foo_dup
functions Looking at the cloning code at perlio.c, Yitzchak Scott-Thoennes
found a spot in *_dup
functions which was probably wrong
and suggested a fix, seconded by Gisle Aas and Rafael Garcia-Suarez
which applied it as change #26799.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00469.html
PERL_UNUSED_DECL
redefined While building Digest::SHA
, Yitzchak Scott-Thoennes
noticed a warning about redefining PERL_UNUSED_DECL
.
It was fixed by copying a newer ppport.h
(any of the 3 others under ext/), which remembered
Rafael Garcia-Suarez of an old idea to compile Devel::PPPort
first and use its ppport.h everywhere.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00470.html
local($[) = 0
In RT ticket #38207, David Dyck reported a "Useless localization of constant"
in getopts.pl: local($[) = 0;
, that led Rafael Garcia-Suarez
to the conclusion that something changed in blead that broke
the special case handling of local $[
supported for perl 4 compatibility.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00475.html
Compress::Zlib
Fights Smokes And Paul Marquess brought another fix to Compress::Zlib
trying to shut up an intermittent failure which keeps showing up on the smokes.
Applied as change #26800.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00484.html
DB_File
and Berkeley DB 4.4 Jeff Earickson opened ticket #38213 to say about a failure
testing DB_File
against Berkeley DB 4.4.16.
Paul Marquess explained 5.8.8 already allows DB_File
to build
with db 4.4 and the the most recent CPAN version had this support.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00490.html
Brendan O'Dea noticed how tricky is to portably use Fcntl
locking
and proposed a patch with a function to pack/unpack flock
structures. Warnocked so far.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00491.html
This week, David Landgren started a crusade to remove
indirect notation examples from POD all over the core
modules. He started with IO::File
and IO::??
While on this, Jim Cromie had suggestions for some
improvements/additions to docs, which were absorbed.
chromatic welcomed David's campaign.
And then, David went on to apply this to
IO::Pipe
and IO::Handle
together with some sundry cleanups.
The no-indirect-notation campaign boils down to this: instead of writing
$fh = new IO::File;
which is considered bad practice in some circles, the following is preferrable:
$fh = IO::File->new;
David Landgren tidies up IO::* modules http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00494.html
Nicholas Clark wondered about a piece code in Perl_save_re_context and brainstormed on how to make saving/restoring regexp states with less computational effort. Hugo van der Sanden and Abhijit Menon-Sen essayed some clues.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00495.html
Nicholas Clark did a check to find dual-life modules which differ
between maint and 5.8.7, but have the same version. This prompted
Marcus Holland-Moritz to explain about Devel::PPPort
releases,
which led Nicholas to integrate 3.06_01 to blead. Jan Dubois also
explained about the status of Win32
and some plans
for future releases.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00503.html
Ken Hirsch brought some patches which only affect MPE/iX platform.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00504.html
B::Deparse
Chokes in 5.8.0 Lionel Cons, in bug #38214, showed how perl 5.8.0 dislikes a
simple assignment with split via B::Deparse
.
$ perl -MO=Deparse -e '@ARGV = split(//, "");' Can't call method "isa" without a package ...
Joshua ben Jore and Paul Johnson helped Lionel to find this is a bug with 5.8.0-threads and that upgrading is the key.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00507.html
ioctl
Charles Howes opened ticket #38223 to tell of a memory corruption
error on a formerly valid code using ioctl
after a Linux core upgrade.
Gisle Aas tracked it down to change #25852 and a probable glibc issue
with _IOC_SIZE
, which called for a fix anyway.
Trusting _IOC_SIZE (Oct 2005) http://dev.perl.org/perl5/list-summaries/2005/20051024.html#More_Platform_Specific_Issues Suspecting _IOC_SIZE http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00535.html
Nicholas Clark tried to remember some binary compatibility
issues with threads and PIDs on Linux due to a change made some time ago.
Jason Vas Dias and Elizabeth Mattijsen know what it was about. Rafael
Garcia-Suarez said the CPAN module Linux::PID
had the
necessary workarounds.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00549.html
my $v if 0
And "fany" opened yet another ticket, #38224, about the weird deprecated usage of
my $foo if 0
. Not that he should have known, but this is almost a FAQ by now.
http://dev.perl.org/perl5/list-summaries/2005/20050926.html#Deprecated_my_$v_if_0 Ticket #38224 http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00561.html
The list of significant changes in Perl 5.8.8, perldelta evolved since its first draft posted by Nicholas through lots of feedback.

CPAN
1.83_55 CPAN reached 1.83_55 and Andreas Koenig resynced it into bleadperl, as change #26858.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00593.html
A bunch of MacOSX-wise people contributed for the update of README.macosx.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00598.html
Encode
2.14 Dan Kogai brought Encode
release 2.14 into blead.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-01/msg00600.html
Nicholas Clark compared the size of perl binaries between 5.9.2 and blead, with the late being the actual winner. Despite several new features, the space optimizing efforts of porters, especially Nicholas, Dave Mitchell, Steve Peters and Andy Lester, outdid them. The same outcome is expected with respect to 5.8.8 against 5.8.7.
