Proposed patches
Aaron Crane provided a [17]patch to [18]Perl #127887 to include a warning
in the documentation of sprintf regarding operations that produce numbers
which cannot be represented by the underlying C layer.
Following an analysis from Hugo van der Sanden, Yves Orton provided a
patch in a branch for [19]Perl #128085.
Discussion
Following a recent [20]blog post regarding the state of [21]Coro and Perl
5.22, Dave Mitchell [22]suggested reverting a commit relating to the
compilation problem mentioned in the blog post. This was an unusual
request considering 5.24.0 was already about to be released. A
conversation continued trying to understand whether Coro could work
without changing core and what original problem Coro worked around, since
no test is available in Coro for the issue. All too quick, Nicholas Clark
[23]provided a patch to build and test Coro that did not require a single
change to core, included no need to revert any commits.
In [24]Perl #127855, Dave Mitchell [25]provides a more in-depth analysis
of SvGROW. A conversation ensued with Yves Orton shedding light on the
interaction of growing SVs (whether SvGROW or sv_grow) and COW.
James E. Keenan had [26]researched mandoc and the patch provided in
[27]Perl #128012, and recommends merging the patch. Another +1 from Karl
Williamson.
