rollback to ruby 19???

Hello,

I have some lengthy scripts that I am running on opensuse 13.2. I am getting occasional segfault errors from ruby. There is a ruby script that is called many times and most times it completes successfully. Every once and a while, the script quits and doesn’t produce output. I have run this many times on an opensuse 12.3 install that is running ruby 1.9.3p392 and I don’t get any errors at all. The errors I am getting are from ruby 2.1.3p242.

I looked in yast, but I don’t see any older versions of ruby available. Is there a reasonable way I can roll back to ruby 1.9 so I can test if that is the issue or not?

I have posted the ruby error output at the bottom of the message in case anyone would find that helpful. I get that this is not a ruby forum but I thought there would be no harm in including it. I can also post the script if that would help. Some of the error output refers to line 130 which is,

prefixes.all? { |x| x==prefixes[0] }||raise

Sorry, I can not comment on your real problem (no ruby experience), but of course there is a reason why you see no older versions of a product in YaST. That is because it is in none of the repositories you use. And that again is rather logical to me. In the OSS repo of openSUSE 13.2 are the versions of the packagess that together are openSUSE 13.2 And not any older versions that are not tested in the Beta phase of openSUSSE 13.2

As you know it is avalable in the 12.3 repo, but I would be very carefull in using it on an openSUSE 13.2.

3

I was not surprised to see that there were no older ruby versions in the package manager, especially since both opensuse and ruby have moved on to new major versions. I was just wondering if my best bet would be to try to find a repository with ruby 1.9, or go some other method such as yum, an installer file, or build from src. Ruby has a tool called RVM (ruby version manager) that is supposed to allow you to manage multiple versions of ruby on the same OS. I have never used it and don’t really know anything about it.

I think the safest thing to do would be to uninstall ruby 2.1 and then install 1.9 from a repository that still has it.
openSUSE-12.3-Oss
http://download.opensuse.org/distribution/12.3/repo/oss/

Do you see any potential land mines with this approach? I can’t think of anything that opensuse 13.2 would need ruby 2.1 for and I don’t need 2.1 for anything in particular.

Thanks,

It will fail hard-core due to library dependencies. A better idea would be to recompile the source rpm against 13.2 if possible.

5

Thanks for the heads up. What would be the advantage/difference in rebuilding the rpm as opposed to downloading and compiling the src as in,

cd /root/
wget http://cache.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p392.tar.gz

tar ruby-1.9.3-p392.tar.gz
cd ruby-1.9.3-p392
./configure
make
make install

The hope is that configure will resolve the dependencies, or at least let you know if they cannot be resolved.

The great thing about the srpm would be the ability to see the deps instantly and being able to uninstall and install a new version easily should you need to.

7

Alright, I will give that a try. This looks like the rpm that I need to recompile,

This is the opensuse 12.x x86_64 rpm for the version of ruby I have on the install that isn’t giving me the errors. I have a few write-ups for recompiling src.rmps and I will read up a bit. Do you have a particular tutorial on the subject that you like? I’ve done more of this kind of thing on fedora, CentOS, etc.

I was planning on completely removing my current ruby installation first.

LMHmedchem

rpmbuild --rebuild SPECS/rubysomething.spec

In your /usr/src/packages

Should do it. Install the source rpm as root.

Writing this on my cell so I might have made a typo somewhere :wink:

9

I appreciate you keeping up with this from your phone. It is still unclear to me if I need to uninstall ruby 2.1 before proceeding.

In Yast, when I select ruby 2.1 for removal, it appears as if there are some other things in there that require ruby, particularly yast2-services-manager. Some of the other items are ruby bindings and lib and such that I would expect to require ruby to be around.

If there are important components of opensuse 13.2 that require ruby 2.1, I could be in Barney as the saying goes.

**Warning…Warning…Will Robertson **

Yast is now written in Ruby if you remove the current Ruby packages you will kill Yast. Possible other stuff.

Got no clue in running two different Ruby versions

11

Well it looks like there is not easy way to run opensuse 13.2 with ruby 1.9 so I went back and installed opensuse 12.3 and have my scripts running. Hopefully the ruby errors are taken care of by going back to the earlier version.

Thanks again for the suggestions. I will keep opensuse 13.2 in a VM and look for ruby updates. I have started a bug with ruby and hopefully they will get the issue resolved.

Not impossible or not that hard - I looked at it and it requires a bit of manual editing of ruby files (like say you can’t have the interpreter called ruby naturally as it’ll break YAST - so it would need to be called “ruby19” or similar) and be installed in a separate directory so it would require a bit of editing the spec files for all the ruby srpms.

I’d say it would take a few hours at most - if there were more than just one person that benefited from this, I could take a look at it and host it on the home:/ repos.

Build a different version of Ruby from a source,

I have been dabbling in learning Ruby and have compiled a version newer
than the one that came with openSUSE installations.

After downloading and compiling in my /home/taki/some_directory,
I make myself a super user ($ su) and # make install.

The files are installed in various /usr/local/ directories.
As a normal user, when I run Ruby executables, those in those in
/usr/local are called, ie, they are given priorities over the
system-installed ones (unless absolute path is given for these).

I have never run Ruby extensively this way. But YAST, for instance, have
always worked fine.

There is a choice to build and install Ruby in /home.

I noticed that no one seemed to suggest starting with installing the 13.2 ruby repository, but it apparently does not include ruby19, so that isn’t an option. Still, if you haven’t done so, you should update your existing ruby with the ruby repository to get all latest ruby packages for openSUSE. Developers should always add the special ruby repository, End-Users might be able to get away with using only the OSS repo.

zypper ar http://download.opensuse.org/repositories/devel:/languages:/ruby:/extensions/openSUSE_13.2/ devel:languages:ruby:extensions

Follow the above which adds the ruby repository with a system update

If that doesn’t solve your problem, then you need to consider running an older version of openSUSE (13.1 supports ruby19). An easy approach is to do this using virtualization (Virtualbox, KVM, VMware and Docker are my recommendations).

If you deploy a virtual Guest dedicated to running ruby19, you may not need to do so but if you do need to run multiple ruby environments you should consider something like RVM to switch between environments.

When you build your Guest (or any other openSUSE running ruby), be sure to add the ruby repo, use the zypper command above modified for the version of openSUSE you are running.
After you do that, if you wish you can also install ruby packages from the official ruby or ruby on rails orgs.
