[Fedora-packaging] Perl autorequires failing for git-svn

[Todd Zullinger]

Hi all,

I'm trying to fix a problem with the git-svn package that causes it to 
not pull in the proper perl dependencies (filed as rhbz #1026760). 
(It's possible I've simply missed an important announcement, but I 
didn't spot anything in the guidelines.)

It appears that the file package was changed from 5.11 in f19 to 5.14 
in f20.  With this change, the git-svn script reports a different type 
and find-requires does not pass it to perl.req for processing.

f19:

<mock-chroot>[root@f20-64 /]# file --version
file-5.11
magic file from /etc/magic:/usr/share/misc/magic

<mock-chroot>[root@f20-64 /]# file /builddir/build/BUILD/git-1.8.4.2/git-svn
/builddir/build/BUILD/git-1.8.4.2/git-svn: Perl script, ASCII text executable

<mock-chroot>[root@f20-64 /]# /usr/lib/rpm/find-requires <<<
/builddir/build/BUILD/git-1.8.4.2/git-svn

/usr/bin/perl
perl >= 0:5.008
perl(Carp)
perl(Digest::MD5)
perl(File::Basename)
perl(File::Find)
perl(File::Path)
perl(File::Spec)
perl(Getopt::Long)
perl(Git)
perl(Git::SVN)
perl(Git::SVN::Editor)
perl(Git::SVN::Fetcher)
perl(Git::SVN::Log)
perl(Git::SVN::Migration)
perl(Git::SVN::Prompt)
perl(Git::SVN::Ra)
perl(Git::SVN::Utils)
perl(IO::File)
perl(IPC::Open3)
perl(lib)
perl(Memoize)
perl(strict)
perl(Term::ReadLine)
perl(vars)
perl(warnings)

f20:

<mock-chroot>[root@f20-64 /]# file --version
file-5.14
magic file from /etc/magic:/usr/share/misc/magic

<mock-chroot>[root@f20-64 /]# file /builddir/build/BUILD/git-1.8.4.2/git-svn
/builddir/build/BUILD/git-1.8.4.2/git-svn: Perl5 module source, ASCII text

<mock-chroot>[root@f20-64 /]# /usr/lib/rpm/find-requires <<<
/builddir/build/BUILD/git-1.8.4.2/git-svn

This fails because find-requires only passes the file to perl.req if 
it's either a .pm file or it's in the script list, which is defined 
like this:

scriptlist=`echo $filelist | xargs -r file | \
           grep -E ":.* (commands|script)[, ]" | cut -d: -f1`

This is where the change in the file commands output is causing 
trouble.

Any help would be much appreciated.

Thanks!
