Bug#800381: libchi-perl: autopkgtest failure: File name too long

[Niko Tyni]

Package: libchi-perl
Version: 0.60-2
User: debian-perl at lists.debian.org
Usertags: autopkgtest

This package fails its autopkgtest checks on ci.debian.net:

  http://ci.debian.net/packages/libc/libchi-perl/unstable/amd64/

This is because the checks are run on an AUFS mount (checked with
terceiro), which has a filename maximum length of 242 bytes. The
libchi-perl test suite limits CHI::Drive::File key length to 240, and
the files have the '.dat' suffix, bringing the length up to 244.

lib/CHI/t/Driver/Subcache.pm has

    # keys for file driver have max length of 255 or so
    # but on windows xp, the full pathname is limited to 255 chars as well
    $keys->{'large'} = scalar( 'ab' x ( $^O eq 'MSWin32' ? 64 : 120 ) );

Patching this to 118 on !MsWin32 should be enough to fix the issue.
