the case of the two rubies

[Stephan Kulow]

Hi,

Now that Klaus' ruby merge is done, I switched the OBS project
to use it - as a test bed of a "product". It's plain impossible
to keep yast and update OBS on 13.1 ;(

We have several things required by yast

libruby2.0.so.2.0 is required by yast2-ruby-bindings and libstorage-ruby
ruby(abi) == 2.0.0 is required by rubygem-ruby-dbus and rubygem-fast_gettext

So not to break yast the OBS "product" needs to provide at least 4
packages linking against ruby 2.1. The libruby2.0 problem will be gone
for future updates as we now have libruby2_1 as a special package, but
the ruby(abi) problem will stay and as I said before: making
/usr/bin/ruby an update-alternative is only a solution as long
as rubygem-fast_gettext isn't required by OBS with a different
ruby abi.

Greetings, Stephan

Yes,
yast bindings is built against ruby that is provided by given release
of opensuse and same for other C-bindings like libstorage. So if you
want base OBS product on 13.1 you should use ruby that is provided
there. And if you want it base on 13.2 then I hope it will have ruby
2.1. It is similar like with any other library or scripting language,
if distribution provide perl 5.10 and you need 5.11, then you need to
somehow bundle it and do work-arounds.

I'm aware - I just presented a case study. And I need to decide now
if bundling ruby 2.1 is worth it ;(

Couldn't you switch to plain rubygem-gettext? I guess it's only a transitive
dependency anyway since I can't recall a German OBS :-)

OBS does not gettext at the moment, no. But software.oo does for example
and we won't be able to hold yast on the VM running software.oo soon ;(

... if deployed from packages - deploying our rails apps (including OBS)
the "bundler/rvm way" is of course a valid option if we can't replace ruby.

Do you mean OBS as the build object, not subject?
https://build.opensuse.org/project/monitor/OBS:Server:2.5
I was quite confused before I understood that.

FWIW, as the upstream for rubygem-ruby-dbus I can say that it works
with any Ruby version >= 1.9. I am not sure whether we should try
packaging some gems as independent on the Ruby version.
