News and highlights
Perl 5.25.4 is now [1]available!
There's a suggestion to dual-life [2]Hash::Util. This would allow
moving a
function there and deprecating it in the Internals:: namespace.
Dave Mitchell [3]suggested to improving the output of high hints bits
displayed in [4]B::Concise. That has been done following the suggestion.
Dave Mitchell also found a specific check in the internal av_fetch
function which slows down all array fetches and doesn't even cover more
than one particular way in which a problem could be triggered. Dave
[5]suggested removing it, which makes sense. This had also been done
following the suggestion.
Ricardo Signes pinged the topic of being able to write state(@a) in
[6]Perl #114932.
A surge of new tickets provided by Brian Carpenter who is diligently
fuzzing perl. Brian also wrote a [7]blog post about it.

Suggested patches
Bulk88 provides an alternative patch in [41]Perl #128930 (automatically
detect GCC vs VC and set VC ver number on Win32) which was merged.
James E. Keenan provided a new patch for [42]Perl #128856: DirHandle:
Improve test coverage and provide descriptions., based on Tony Cook's
feedback.
Karen Etheridge provided a patch in [43]Perl #128987: to upgrade
[44]CPAN::Meta to 2.150010.
To address HP-UX problems, H. Merijn Brand (Tux) [45]suggested (Getting
HP-UX smokes green again) a patch.
Discussion
Jarkko Hietaniemi continues running Coverty on the codebase and [46]found
another group of errors relating to utf8 which are a bit odd. Aristotle
Pagaltzis provided the background for the mentioned code.
If you're interested in how the lexing and parsing code of perl, Dave
Mitchell [47]provided an analysis of [48]Perl #128951
(heap-buffer-overflow in Perl_sv_vcatpvfn_flags). Father Chrysostomos
interjected to look into fixing it (which he did). I must include Dave's
comment to Father C.:
Isn't it handy that people have such differing concepts of what
constitutes 'fun'? Yes, please do take over :)
[49]Perl #128950 (possible bug in perl \u string processing) showcases
some of the complexities in Unicode, which I found very interesting. You
might as well.
In an [50]email forwarded from the perl-unicode mailing list, an issue is
raised on the interaction between [51]Encode's utf8 warnings and
flags and
the [52]warning pragma's utf8 warnings.
James E. Keenan [53]asked (lib/perldebug.t: puzzling test failure)
about a
puzzling test failure.
