[DRE-maint] Bug#802762: bundler: Please re-add the /var/lib/gems/<version> directories

[Raphael Hertzog]

Package: bundler
Version: 1.10.6-2
Severity: normal
Tags: patch
User: devel at kali.org
Usertags: origin-kali kali-patch

Hello,

I noticed that in version 1.9.9-1 you stopped shipping the
/var/lib/gems/<version> directories justifying this with a bug of
your own (#782148). The bug is not very clear but apparently
you were not happy of having directories for old versions...

I want those directories back because bundler does not work
out of the box without those directories. At least not for
the use we make of it in Kali.

We have many Ruby applications relying on bundler and we package
all the ruby modules ourselves. At build time we run something
like this to ensure that we have all the modules in the desired
versions.

	# Just ensure that we have the required deps
        bundle install --local --no-cache --without test

But this call fails when /var/lib/gems/<version> does not exist.

So I would like you to apply the attached patch. It will rely
on ruby-all-dev to create only the directories that are actually
needed for the supported ruby versions (right now 2.1.0 and 2.2.0).

Thank you!
