Proposed patches
Shlomi Fish provides a patch in [22]Perl #127690 to add a CONTRIBUTING
section to the [23]Carp module.
Discussion
Achim Gratz [24]asks when the Perl 5.22.2 is expected. Steve Hay adds
that
hopefully before 5.24.
Sawyer X [25]raises a feature request for smokers, to be able to identify
a specific smoker running on a specific operating system, in order to
identify flopping in smoker reports. Craig A. Berry and George Greer
added
some comments about the possible difficulty of such a feature.
Piotr Oniszczuk [26]asks about networking issues after migrating his Perl
5.12 based cross-compilation to GCC 5.
In a very interesting [27]thread, Zefram and Yves Orton discuss the
behavior of regular expressions with regards to possible infinite
recursion. It is not for the faint of heart but it is quite interesting.
Yves then reinstates the 5.22 warning of infinite recursion in regular
expression.
Karl Williamson [28]requested a Configure probe for memmem() in case any
native implementations carry a faster version. Craig A. Berry hasn't
found
a faster native implementation in glibc or the BSD versions.
Jarkko Hietaniemi [29]added support for [30]Cscope, a link to a VIM
plugin, and attached code with support for Emacs.
The conversation about a new quoting operating continues. Brad Gilbert
[31]shares information about how Perl 6 does it, while Ricardo Signes
[32]comments on Aristotle Pagaltzis' comments, to which Father
Chrysostomos [33]adds his two cents.
Bulk88's optimizations in [34]Perl #125296 peaked interest and, along
with
Dave Mitchell's [35]comments, Ricardo Signes has [36]asked for more eyes
and comments on the work.
Ed Avis requested a new regular expression word boundary in [37]Perl
#127670 to handle situations in which you do not know if your requested
search between the word boundaries (/\b/ typically) themselves are words.
Andy Broad [38]asks about a problem he's experiencing with a program
hanging on a mutex under AmigaOS4. Craig A. Berry and Leon Timmermans
helped understand the issue and how to solve it. PerlIO is tricky.
After [39]inquiring about the u flag used in ar during compilation phase,
Dave Mitchell removed the unnecessary flag.
Ulrich Windl suggested a new feature (operators ||| and &&&) in [40]Perl
#127684. There were various suggestions on how to solve the problem
he had
without such operators, notably from [41]Zefram and [42]Abigail.
