Some days ago my box emerges stable gnome 3.16.
Unfortunately now my ruby-gnome2 application (http://ssalewski.de/PetEd.html.en) generates gc related random crashes again. (current ruby-gnome2-2.2.5 was working OK with Ruby 2.2 and Gnome 3.14.)
Update from current ruby-gnome2-2.2.5 to 3.0.2 seems to be not trivial, did a try by just renaming ebuilds yesterday, but compile fails at gtksourceview.
The problem is, that I can not debug the crashes myself, and asking upstream makes not much sense, when I am not running the latest ruby-gnome2.
So a Gentoo update would be really great.
I had a look at this a few days ago, but both 3.0.1 and 3.0.2 had issues with their tests, resulting in failed tests or even segmentation faults. I did not even get to gtksourceview. Given our current workload my strategy is to wait for new upstream releases.
Of course my hope was that 3.0.2 would work perfectly ;-)
Yesterday I recompiled all the 2.2.5 packages and after that got only one crash for 10 minutes of testing, that is not so bad.
Indeed my long time goal is to port my application to Nim, I did already all the necessary wrapper/bindings for GTK 3.15.xx. But porting the application is some work, Nim code generally is more similar to Python than to Ruby. (Porting to Crystal instead would be also an option, they have started working on a introspection based GTK3 wrapper.) But in the next months I will finish the Ruby version, maybe I find a way to avoid the crashes, or maybe I can try the gems install.
ruby-gnome2 3.0.7 has been added to the gentoo repository.
