15 years agoNo need to run AutoSplit on lib - all AutoLoader using modules are in ext.
Nicholas Clark [Fri, 11 Sep 2009 21:07:01 +0000]
No need to run AutoSplit on lib - all AutoLoader using modules are in ext.

It seems that the code in the Makefile to run AutoSplit over lib has actually
been vestigial since some point *before* 5.000. Presumably, initially, Perl code
for extensions was in lib, and autosplit (the precursor to AutoSplit.pm) was run
on them there. Or they were copied from ext to lib first, before splitting.
Fifteen year-old backup tapes refuse to give us the detailed history of the
pre-5.000 period.

Whatever the cause, the code was never needed - backed up by the absense of any
analgous code in the Win32 Makefiles. So remove it. This happens to also remove
the only use of the shell script makedir, so remove it too.

Nicholas Clark [Fri, 11 Sep 2009 20:29:53 +0000]
Always load the re.xs code, unless we're running under miniperl.

This is a lot simpler than the previous implementation, which would lazy load
the XS code only if it was needed, and then jump through more hopes to try to
give the user a reasonable error message if it failed.

In the real world, people either have a full perl installed with the re
extension, or their install is already horribly broken. Don't let code related
to bootstrapping the core build pollute the installation.

15 years agoDon't modify namelen in the first half of gv_stashpvn()
Vincent Pit [Thu, 10 Sep 2009 16:20:06 +0000]
Don't modify namelen in the first half of gv_stashpvn()

As it may be needed later when the lookup failed.

This fixes [perl #69066].

However, from now, "package ::" and "package foo::" respectively introduce
the "::" and "foo::" packages. Deciding if this is the correct thing to do
ought to be addressed separately.

(It's needed by 00compile.t)

15 years agoMove ExtUtils::MakeMaker from lib to ext.
Nicholas Clark [Thu, 10 Sep 2009 15:58:33 +0000]
Move ExtUtils::MakeMaker from lib to ext.

t/lib/TieOut.pm is now from Test::Simple.

Only the tests needed changing. The exceptions to BEGIN/PERL_CORE/INC
boilerplate removal were two instances of "../.." becoming "../../../..",
and changing an %INC test from "strict.pm" to "less.pm", as TestInit causes
strict to be loaded via a relative path, when it loads File::Spec to convert
all paths from relative to absolute.

15 years agoUpdate Archive::Tar to CPAN version 1.54
Chris Williams [Thu, 10 Sep 2009 12:54:09 +0000]
Update Archive::Tar to CPAN version 1.54

    * important changes in version 1.54 10/09/2009
    - Apply a patch from Niko Tyni (ntyni@debian.org) that resolves RT #48879;

    As seen in [rt.cpan.org #48879], although the recommended way of
    retrieving the last error is to use an instance method ($tar->error),
    the returned value is effectively global: an error in one Archive::Tar
    instance changes the error string of another instance.

    This change separates the error strings from each other while keeping
    the (deprecated) global value of $Archive::Tar::error pointing to the
    last error regardless of its instance.

    We also support calling error() as a class method (Archive::Tar->error).
    In this case it returns the global value, which matches the old behaviour.
