Full Discussion: Migrating perl code from 32 to 64 bit OS
Top Forums UNIX for Advanced & Expert Users Migrating perl code from 32 to 64 bit OS Post 73602 by cbkihong on Thursday 2nd of June 2005 08:32:57 PM

Probably unless you do some binary stuff, which is sensitive to how data are physically packed, Perl is largely platform independent. But the deeper you go, the more likely you will hit non-portable aspects (I guess XS apps or modules, which involves an intimate C-Perl binding, needs to be at least recompiled).

If you use pack() and unpack() functions, chances are you may run into portability problems as well.

git-unpack-objects

GIT-UNPACK-OBJECTS(1)						    Git Manual						     GIT-UNPACK-OBJECTS(1)

NAME

       git-unpack-objects - Unpack objects from a packed archive

SYNOPSIS

       git unpack-objects [-n] [-q] [-r] [--strict] < <pack-file>

DESCRIPTION

       Read a packed archive (.pack) from the standard input, expanding the objects contained within and writing them into the repository in
       "loose" (one object per file) format.

       Objects that already exist in the repository will not be unpacked from the pack-file. Therefore, nothing will be unpacked if you use this
       command on a pack-file that exists within the target repository.

       See git-repack(1) for options to generate new packs and replace existing ones.

OPTIONS

       -n
	   Dry run. Check the pack file without actually unpacking the objects.

       -q
	   The command usually shows percentage progress. This flag suppresses it.

       -r
	   When unpacking a corrupt packfile, the command dies at the first corruption. This flag tells it to keep going and make the best effort
	   to recover as many objects as possible.

       --strict
	   Don't write objects with broken content or links.
