=head1 This Week on perl5-porters - 26 January-1 February 2009

=head1 Topics of Interest

=head2 Re: merging make_ext and make_ext_cross

  http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2009-02/msg00013.html

=head2 Need advice on gotchas on upgrading unicode db to 5.1

Yves Orton reminded Karl Williamson that the filenames produced by
the Unicode build phase need to behave correctly in the light of
case-insensitive filesystems. Karl explained that C<mktables> goes
as far as ensuring compatibility with 8.3 filesystems.

  http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2009-02/msg00014.html

=head2 Deprecate C<UNIVERSAL-E<gt>import>

Ricardo Signes introduced a lexical "this is deprecated" warning for
people who write C<UNIVERSAL-E<gt>import>, since they're not
supposed to anyway. Surprisingly, the test suite didn't complain.

  http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2009-01/msg00785.html

=head2 5.10.0 Source Tree Update Problem

Dave Mitchell needs to merge the git config tweaks in blead back
into 5.10 to allow testers to smoke anew. Jerry D. Hedden pointed
to a patch that needs to be applied to fix the patchnum situation.

  http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2009-01/msg00814.html

=head2 C<Storable::nstore_fd> + 'E<gt>:raw' pragma

David Williams reported a 20x slowdown when writing out a C<Storable>
data structure. Eric Brine and Bo Lindbergh suggested that this was
more a problem of documentation than anything else.

  http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2009-01/msg00815.html

=head2 Make F<t/win32/system.t> use the more common compiler check

Max Maischein tweaked the Win32 test suite to follow the existing
best practices for identifying the compiler used. Andy Dougherty
pointed out that the current best practices were sub-optimal and there
was a better way, that Win32 would do well to adhere to, even if
Unix-like platforms don't right now.

In the final analysis, Andy wondered why tests even cared which
compiler was used to build perl.

  http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2009-01/msg00797.html

=head2 Git commits and branches

Jerry D. Hedden was puzzled by a commit reporting itself as apparently
belonging to a 5.8 change, and wondered why it didn't in fact report
itself as a 5.10 change. Rafaël Garcia-Suarez explained why it was
so, and Sam Vilain explained what it would take in order straighten
out the history

  a bit of graft
  http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2009-01/msg00820.html

=head2 Understanding merge history

And on the subject of git, Dave Mitchell professed to being a bit
lost in the brave new world of git, and was looking for clues to
help him figure out what (and how) to cherry-pick commits from
blead for 5.10.

The problem appears to be sufficiently hairy that, while there is
little doubt that git can do it, the question is how to ask for it.

  http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2009-01/msg00830.html

=head2 C<perldelta> omission for 5.8.9?

Ricardo Signes was surprised the C<qr/.../m> improvement in blead
and 5.10 made it back in time for the 5.8.9 release, and that it
didn't rate a mention in the C<perldelta> file, since it is a
behavioural change.

  but it's for the better
  http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2009-01/msg00844.html

=head2 C<PerlIO::via> open fails for certain names

Scott Lanning want to use IO layers and ran into peculiar problems
that were difficult to diagnose. After some discussion, Rafaël
thought he had a fix for the matter.

Chris Hall pointed out some inconsistencies in Perl's implementation of
text-to-native-floating-point conversions. One minor hassle that Nicholas
Clark remembers about the matter is that it is impossible to have an
implementation compatible with both C89 and C99 since they are mutually
inconsistent.

=head1 In Brief

Dave Mitchell is starting the arduous task of producing B<F<perldelta5101>>,
the changes in perl 5.10.1.

  volunteers sought
  http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2009-01/msg00778.html

Nicholas Clark would like to know B<where is F<Cross.pm>>, in the context of
merging C<make_ext> and C<make_ext_cross>.

  http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2009-01/msg00878.html

Max Maischein has probably succeeded in getting B<F<lib/Tie/RefHash/threaded.t>
to pass on Win32/MinGWgcc>.

  works for me
  http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2009-01/msg00740.html

Max also B<unbroke the build on Windows> that had suffered at the hands of
to a refactoring of F<make_patchnum.pl>.

  just so you know who to blame
  http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2009-01/msg00756.html

Scott Lanning tweaked the grammar via a B<doc patch for C<PerlIO>>.

  gooder
  http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2009-01/msg00748.html

That Karl Williamson doesn know B<what C</\p{CanonicalCombiningClass:AL}/> should
match> probably points to an error in C<mktables>.
