January 11th-24th
This summary contains two weeks, as time was too short for a summary last
week.
News and updates
[1]perl 5.23.7 is now [2]available, thanks to Stevan Little!
The epigraph provided below:
A year here and he still dreamed of cyberspace, hope fading
nightly. All
the speed he took, all the turns he'd taken and the corners he cut in
Night City, and he'd still see the matrix in his dreams, bright
lattices
of logic unfolding across that colourless void...The Sprawl was a long,
strange way home now over the Pacific, and he was no Console Man, no
cyberspace cowboy. Just another hustler, trying to make it through. But
the dreams came on in the Japanese night like livewire voodoo, and he'd
cry for it, cry in his sleep, and wake alone in the dark, curled in his
capsule in some coffin hotel, hands clawed into the bedslab, temper
foam
bunched between his fingers, trying to reach the console that wasn't
there.
-- William Gibson, Neuromancer
[3]Encode 2.79 is released!
[4]podlators 4.05 is released!
Tony Cook provides his [5]10th and [6]11th reports for his 6th grant. A
total of 38 hours of work, with 27 tickets reviewed or worked on, and 4
patches applied.
Dave Mitchell provides his grant [7]reports. He worked a total of 5.5
hours these past two weeks, mainly on tweaking Porting/bench.pl to
display
results for just a single executable in a more compact form.
Aaron Crane had reduced the problem in [8]Perl #127323 (segfault with
[9]Storable) to a problem with [10]JSON::XS or [11]Cpanel::JSON::XS.
Dave Mitchell removed usages of PRIVSHIFT from the source code, more
details available [12]here.
Karl Williamson [13]updates the list about proposed update [14]UTS #39,
Unicode Security Mechanism.
Karl Williamson [15]notes that qr/\b{lb}/ is now added to bleadperl,
providing the final Unicode boundary type previous missing from core
Perl:
the LineBreak.

Proposed patches
Tony Cook provided several patches, namely for: * [39]Perl #127149 *
[40]Perl #127061 (in which he explains still has two failing tests, so
should not be merged yet.) * [41]Perl #126410 * [42]Perl #124387 *
[43]Perl #127063 * [44]Perl #125540
Dagfinn Ilmari Mannsåker provided a patch for [45]Perl #121351 to replace
the use of PL_timebuf with auto variables.
Bulk88 provided a set of patches in [46]Perl #127260 for the new threaded
[47]mem. allocator for Win32 perl.
Niko Tyni provided a patch in [48]Perl #127288 to set UTF8 flag in
[49]I18N::Langinfo.
Salvador Fandiño provided a [50]patch to fix sorting with custom
subroutines returning big numbers.
Matthew Horsfall provided a patch to fix [51]Perl #6997 where multiple
concatenations in void context do not trigger a warnings, explaining the
reasons for it.
Discussion
After smoking CPAN, Dave Mitchell [52]provides a patch for
[53]Scope::Upper which helps pass most of the tests. Dave adds that
Scope::Upper can probably be reworked so it does not fail with the new
context stack system, but lacks the tuits to do it himself. Vincent Pit
(author of Scope::Upper) notes that it might work but he does not
have the
time to do the work now or in the near future.
Dave asks whether, given Scope::Upper can be fixed to work, anyone
has any
objections to merging the new context stack system.
Craig A. Berry provided [54]details on how to handle releasing XS
distributions from ./dist directory.
Aaron Crane worked on fixing the ABI incompatibility with -DDEBUGGING vs.
without (raised in [55]Perl #127212), but it seems a bit trickier than
initially thought.
Chad Granum [56]provided an update on the conversation regarding the
proposal to provide renaming features in [57]Exporter, with a link to a
[58]blog post regarding [59]Importer.
Dagfinn Ilmari Mannsåker [60]asks about exposing more of the siginfo_t
fields to the sigaction callback when setting SA_SIGINFO. He provided a
smoked branch.
Todd Rinaldo asks in [61]Perl #127318 if it makes sense for perl to
die if
an item in @INC is inaccessible, as [62]Perl #113422 addressed. Zefram
notes the previous behavior was surprising and earlier errors should not
be ignored.
Andreas Koenig and Steve Hay are [63]trying to update [64]CPAN.pm in
core.
Karl Williamson forwarded an [65]email from the perl-mvs list hoping
someone might be able to help, relating to warnings compiling perl 5.22.1
on z/OS.
Karl also [66]asks about a Unicode algorithm problem and possibly a re
program to switch between two different meanings for qr/\b{sb}/.
