News and updates
Sawyer X [1]reports that this month will see a release of another
development release (instead of next month) in order to accommodate
changes which waited until 5.24.0 and 5.25.0 were released.
Tony Cook provided his [2]grant [3]reports. In total about 32 hours and
approximately 16 tickets were reviewed or working on, and 1 patch
applied.
Dave Mitchell provided his grant [4]report. The majority of the work was
done to try and make [5]Scope::Upper work on 5.24.0.
Craig A. Berry announced that binary kits of Perl 5.24.0 for OpenVMS are
now [6]available.

Proposed patches
Maxwell Hadyn provided a patch in [42]Perl #128105 to clarify the
description of sprintf %.1g in perlfunc.
Jim Cromie provided a patch in [43]Perl #128112 to improve the bug
handling of glibc i-modulo.
Chad Granum (Exordist) provided a patch in [44]Perl #128113 to upgrade
[45]Test-Simple in perl blead.
Lukas Mai provided a patch for [46]Perl #128131 to fix the link-time
optimization (LTO) for GCC 6.
Salvador Fandiño provided a [47]patch to fix a [48]PerlIO::encoding test.
Tony Cook provided a patch in [49]Perl #126228.
Karen Etheridge provided a patch in [50]Perl #128153 to upgrade
[51]Module::Metadata to 1.000032 and another in [52]Perl #128160 to
silence some diagnostic messages that were printed with the first patch.
Karen also submitted a patch in [53]Perl #128169 to remove internal test
modules from [54]Module::CoreList.
Jerry D. Hedden provided patches to update [55]threads and
[56]threads::shared to 2.08 and 1.52, respectively.
Discussion
Mojca Miklavec has taken over maintainership of perl5 in MacPorts and
[57]asks for advise on the appropriate configuration flags. An [58]answer
provided by Craig A. Berry.
James E. Keenan set up a smoke branch to test the upgrade patch in
[59]Perl #128113 (mentioned above) and asks whether we should still merge
to blead for sensitive distributions. Tony Cook intends to apply the
patch
soon. Tony [60]provided some benchmark results, and Chad Granum
[61]provided an explanation of possible differences.
The discussion about removing . from @INC is continuing, thanks to
constant bumps from Todd Rinaldo. I recommend [62]reading about the topic
and its possible effects and various offered solutions.
Ricardo Signes [63]asks if anything is preventing us from moving lexical
subroutines from "experimental". Father Chrysostomos mentions [64]Perl
#123367.
H. Merijn Brand (Tux) [65]reports he benchmarked Perl 5.24.0 and [66]sees
an improvement in speed.
Timothy Madden [67]asked how to use I/O from native C extensions. Leon
Timmermands [68]provides an answer.
Karl Williamson [69]reminds everyone to update all RT tickets for 5.26
pending release.
Aaron Crane [70]asks about a proposal to deprecated and remove a
C-specific function from [71]POSIX.pm.
Following no objections, Dave Mitchell had [72]set -DPERL_PARENT_OP as
default.
Alberto Simões [73]asks about the return keyword behavior in a map block.
Note-worthy, Aaron Crane's [74]explanation for a particular bug.
H. Merijn (Tux) Brand [75]had# a problem which Zefram pinned to a check
done on the shebang for Perl 6 which created a false positive. There's an
active discussion on whether the check should be reverted or kept.
Karl Williamson [76]asks about [77]Perl #57512 (implicit close()s are
silently unchecked for error). Ricardo Signes explains the problem and
Father Chrysostomos elaborates. It would seem that under the new context
stack Dave Mitchell has written, this class of errors could be fixed.
Karl Williamson [78]simplified and generalized mathom.c, which is a file
that keeps several definitions, originally meant for binary
compatibility.
Dave Mitchell suggests cleaning up up after every stable release.
