News and updates
Dave Mitchell provides his grant [1]report. The majority of the work was
fixing [2]Scope::Upper.
Dave Mitchell also provides more detailed [3]grant [4]reports.
Perl now warns if you accidentally left version control markers! See more
in [5]Perl #127993.

Proposed patches
Father Chrysostomos opened [22]Perl #128294 to skip tests of prereq
modules in an internal utility, bisect-runner.pl. After discussions, this
resulted in a patch to provide a skip functionality flag,
--no-modules-tests.
Chad Granum provided a [23]patch to update [24]Test-Simple to the latest
version, including silencing some noise and test failures. Chad also
provided a patch in [25]Perl #128337.
Sullivan Beck provided a [26]patch to bump [27]Locale::Codes from 3.38 to
3.39.
Following a conversation with Zefram and Tony Cook on the IRC channel,
Breno G. de Oliveira provided a patch in [28]Perl #128301 to test which
operations "eagerly" create a hash entry. Zefram notes there are several
other cases which we should cover in tests, while we're addressing this,
and provides sample code.
Dominic Hargreaves [29]sent a patch to address an assertion failure.
Discussion
Smylers [30]notes that perlpodspec still promotes [31]Pod::Parser despite
being cleaned up by Karl Williamson as part of [32]Perl #119439. Karl
Williamson responds with further explanations on some of the finer points
of replacing those bits in the docs in favor of [33]Pod::Simple. Seems a
bit difficult.
Smylers created [34]Perl #128302 mentioning that the documentation for
split do not mention that it can use pattern modifiers. The
[35]explanation (by Father Chrysostomos) is that a m// op is created at
compile time, which itself can have pattern modifiers. Abigail [36]notes
that some (for example, /g) produce a warning.
Andy Dougherty [37]notes that the change in Configure to make -O the
default behavior has unintentionally introduced some breakage. Andy
analyzes the problem and asks, was this worth it? You can find more about
the problems raised in [38]Perl #128295.
[39]ExtUtils::MakeMaker 7.18 has breaking tests on Windows, both in
Jenkins and smoking. This was eventually [40]resolved upstream.
An aside from usual business, a user [41]emailed about possible
performance degradation in a script using OpenSSL. This was debugged as a
benchmark problem, an OpenSSL function call, and a network issue.
Andy Lester provides a patch to fix a typo in perlhacktips pod in
[42]Perl
#128331.
Karl Williamson [43]asks to take a look at [44]perltodo and update it.
Karl Williamson [45]suggested deprecating the ability to quantify
zero-length constructs in regular expressions. Why quantify nothing?
Abigail [46]notes that if you're generating code, deprecating this is not
desired.
Father Chrysostomos [47]asks for help debugging a program which seldom
crashes. Lessons learned? There are various tools: gdb, valgrind, clang
with address sanitizer, and [48]rr.
Dan Collins [49]sparked a conversation about the possible problems with
in-place sort optimization. You can read additional thoughts in a ticket
Zefram opened following this, [50]Perl #128340.
Dan Collins had also been working on testing some old bugs. After
verifying [51]Perl #128313, he worked on a solution. You see his progress
[52]here.
