Ruby-gnome2 not fully functional (at least for me) in latest ubuntu (karmic)

Desktop Ruby-Gnome 2
1

Hi,

I’ve noticed that my program booh lacks screen refresh on ubuntu
karmic (rg2 0.19.0) when calling backend programs. I fork and use ruby
threads to monitor the progress of the backend programs (and
pulse/increment progressbars). I use mandriva (rg2 0.19.2) and I have
no problem.

That simple program seems to reproduce:

http://zarb.org/~gc/t/threaded-example.rb

E.g. when the button is clicked in that example program, the interface
becomes unresponsive for 3 seconds on ubuntu (the button remains
“pushed” and nothing more happens) but it should not. Remove the
Thread{} waiting for process completion and it will workaround the
problem (but I need to wait for process completion in my real program,
of course).

I suspect one of the fix of rg2 0.19.2 (released Wed, Sep 23, 2009) to
be the culprit:

  • [#2862022] fix multi thread blocking with Ruby
    1.8.6-p368 or later and 1.8.7-p173 or later.
    [Roy W., Andrea D., Kouhei S.]

Any Ubuntu-aware person can suggest a solution? Would the 0.19.0 be
fixed or upgraded?

Thanks,

Hi Guillaume,

I also have the same problem on ubuntu karmic, but did not find the
solution.
I just tried my tool gnms (http://gnms.rubyforge.org/) yesterday, but
it seems to freeze in some thread on my ubuntu.
If you are right I believe the patch should be removed/modified.

there’s no patch to remove/modify. the commit I talked about was done
between 0.19.1 and 0.19.2, and karmic is stalled on 0.19.0. either the
commit should be used on 0.19.0 or (better) the whole should be
upgraded.

oh ok, I know it’s hard to get ruby-gnome2 updated in Ubuntu, maybe we
should fill a bug entry in launchpad … and see

I was hoping an ubuntu developer/packager was listening in this list…
but maybe not…
