Comment 148 for bug 578215

Hi Alejandro,

thanks a lot for the information! Some of it I do understand, some I don't. I myself have the project lead in a commercial development project where not all the time I do understand the dependencies. The whole KDE 4.x - project, is there anyone who understands the dependencies and the release plan (if there is one)?

Talking about this issue: What shall we do, reopen it or keep it running in parallel?

Only someone who really understands how the different parts work together could track an issue like that. I myself do not have time and (no longer) patience to do so.

I am a KDE/Linux user who tried to help but stopped writing bug reports because there are too many. I have no idea where to start and where this might end!

Regards, Martin

>
> - Virtuoso being locked up with strigi, one core sleeping - killed with

> - Various memory leaks, some with Virtuoso, some with nepomukstorage, and

> - Virtuoso being locked up with akonadi-nepomuk-email-feeder, one core
> wasted.
> That one haunted KDE 4.7.x until ~4.7.4.
> - Virtuoso being locked up with akonadi-nepomuk-feeder, one core wasted.
> That

> All of these real issues were amplified by more downstream issues.

> - Strigi lacks a real release policy. During most of 2010 and part of

> Debian shipped Strigi 0.7.2, an extremely buggy and ancient release.
> - Akonadi and Soprano are not updated with KDE, in KDE dependent distros.

> So, you can't really fix this, unless:

> - You require a Virtuoso + Soprano + Akonadi + Strigi + Shared Desktop
> Ontologies stack, and maintain it with a KDE 4.x release cycle.
> - You assign a real maintainer to akonadi-nepomuk-feeder (that package is
> somewhat orphan, unlike Nepomuk).
> - You REQUIRE distros shipping KDE to UPDATE their packages. That can be
> made
> easily through CMakeFiles (if you ship KDE 4.8, then you must have certain
> versions of Soprano, Akonadi, Strigi and shared-desktop-ontologies)
> - You MAKE a "Update my Ontologies" app like what Bangarang has. That's a
> necessity.
