Request for breaking hard feature freeze for an important Nepomuk service

[Sebastian Trüg]

Hi guys,

we are in feature freeze which means the fact that this feature is in the 
feature plan for 4.1 does not help me anymore.
But I think this is important:

When moving files that have been tagged or rated or commented around you lose 
the information because Nepomuk relates the files and resources by URL.

So far I have no perfect solution for this problem since both FAM and inotify 
are not sufficient to track all files.

But now the filewatch service uses at least KDirNotify (just learned about 
that one) and inotify to watch for changes. This means that user that only 
use KDE apps to handle their files will have no trouble. Everyone else will 
also stay out of trouble unless they have more than 8000 something files in 
their home directory (inotify's default limit) or they tag files outside of 
the home dir.

This is not perfect but so far I don't have a perfect solution.

One more thing before you ask: I use inotify and not FAM because FAM does not 
support move operations the way I need them: I need to know the source and 
destination of the operation. Only inotify provides that.

Some more details:
* It is a Nepomuk service and would live in kdebase/runtime/nepomuk/services 
  (it currently resides in playground/base/nepomuk-kde/filewatch)
* I have no replacement for inotify on Windows or MAC yet (KDirWatch cannot be
  used for the same reason as FAM)

If there are no objections (hopefully) I would move the service into kdereview 
for you to look over it. I think there are still some Windows/MAC specific 
ifdefs to be done.

Thanks a lot for considering.
Cheers,
Sebastian
