Module-Build 0.14

on Perl CPAN

Added support for MacPerl (Mac OS version 9 and below), which (as
far as I know) was never natively supported by MakeMaker. Still
lacks support for the 'test' action (because Test::Harness
requires forking, which MacPerl won't do) and compiling XS/C files
(because I don't know how to invoke a compiler on MacOS, and one
may not even be available). This change is brought to you by
Michael Schwern and the letter '('.

Improved processing of .xs files. Now we use the new
ExtUtils::ParseXS module if it's available, otherwise we use
backticks and write the result to a .c file ourselves. This
avoids the need to do cross-platform shell redirection.

Make sure all parts of 'Build test' use the not-yet-installed
version of Module::Build. This only affects the tests for this
module, not any of the module code itself. [Spotted by Schwern]

Oopsie - use $Config{ld} instead of $Config{cc} for linking.

Added a 'diff' action, which is useful for comparing the details
of what you're about to install with what is already installed on
your system. This uses File::Compare, which is in the core.

Fixed a problem on Windows in which the _build/ directory wasn't
getting deleted during the 'realclean' action, because we had a
file open in that directory. [Spotted by Michael Schwern]

delete_filetree() now always uses File::Path::rmtree(), regardless
of whether the thing being deleted is a file or a directory. This
helps remove things on obscure platforms with strange locking
rules (or even not so obscure ones like MacOS). It also now
reports the number of files or directories deleted (without
recursing directory contents).

rm_previous_build_script() is gone, replaced by calls to
delete_filetree().

'Build' now chdir()s in a BEGIN block, so the 'use Module::Build'
statement will work correctly. Solves a problem on MacOS, where
the 'Build' script may often be invoked from the wrong working
directory. [Fix by Michael Schwern]

Internally we now use the multi-argument form of system() to run
external commands (such as 'diff' or 'cc') whenever possible (and
whenever we can't avoid system() altogether). Note that this
means we have to handle splitting some strings (such as
$Config{ccflags}) into argument lists like the shell would, which
is a drag. However, the alternative would be to handle shell
quoting of all arguments to commands ourselves, which is an even
bigger drag across platforms and involves arbitrary filenames and
so on.

To handle the argument splitting mentioned above, a method
split_like_shell() has been created. So far it's just doing naive
processing. In practice, I've yet to actually see a %Config entry
that uses quotes & spaces, so the splitting task is usually not
very error-prone.

The 'test' action now takes a 'test_files' parameter, similar to
the (undocumented) ExtUtils::MakeMaker TEST_FILES argument. Handy
during development when fixing bugs.

Internally, the rscan_dir() method can now accept a predicate
function that decides whether a file/directory should be matched.

We now issue a warning message when the author hasn't specified a
license type.
