Description of problem:

When I build Module-Build-Tiny using the Mageia perl, then the tests fail. It's OK with a perl-5.18.0 on perlbrew:

Please report the bug upstream. Even if it works fine with a perlbrew 5.18, it most likely is due to a weird interaction with some otherwise perfectly fine perl build options.

Indeed, I don't really think our chmod is broken. :-)

OK, I'll try to pinpoint the problem and report it upstream.

The perl that is built and installed using this script is able to pass the tests of Module-Build-Tiny perfectly fine:

Hi Jerome,

after some amount of investigation, I found out that the problem was likely caused by the patch perl-5.12.0-RC0-install-files-using-chmod-644.patch to the Mageia "perl" package that reads:

This is an old patch from 2009 applied against perl-5.12.0 originally. Do we really need it.

Thus the problem is specific with the Mageia perl.

After commenting out the application of this patch in svn+ssh://svn.mageia.org/svn/packages/cauldron/perl/current/SPECS/perl.spec , I was able to successfully build and install perl and now the tests of Module-Build-Tiny succeed. Can we rebuild perl without this patch?

This bug applies to Mageia 3 aswell.

Comment 7 Jerome Quelin 2014-02-24 09:31:17 CET
Sorry for the time to answer to this bug - real life kicked in.

So I ack-ed Shlomi to remove the faulty patch in cauldron, which he did on 2013-06-18 (http://svnweb.mageia.org/packages?view=revision&revision=444674).

Cauldron is now fixed, and mageia 4 too (patching done before branching mga4).
==> we need to do that for mageia 3 also?

Pros:
- bug exists in mga3
- mga3 eol is 2014-11-19

Cons:
- mga4 is already out, with a fixed perl
- module::build::tiny can be installed if really neeeded (force install)
- qa is overwhelmed with updates, so easing their workload would be nice
- perl is a critical package, and I prefer limiting its amount of updates to the very strict minimum.

So I'm waiting for your input before actually issuing an update. If you think that we should have an update for mga3, please speak up now and I'll do it. Otherwise we'll close as resolved/fixed.

Thank you - now NEEDINFO.

For what it's worth, I don't think we should update the perl in Mageia 3.
