| libtask-weaken-perl | Ensure that a platform has weaken support | Mehr ... |
One recurring problem in modules that use Scalar::Util's weaken
function is that it is not present in the pure-perl variant.
.
While this isn't necesarily always a problem in a straight CPAN-based
Perl environment, some operating system distributions only include the
pure-Perl versions, don't include the XS version, and so weaken is
then "missing" from the platform, despite passing a dependency on
Scalar::Util successfully.
.
The normal solution is to manually write tests in each distribution
to ensure that weaken is available.
.
This restores the functionality testing to a dependency you do once in your
Makefile.PL, rather than something you have to write extra tests for each
time you write a module.
.
It should also help make the package auto-generators for the various
operating systems play more nicely, because it introduces a dependency
that they have to have a proper weaken in order to work. |
