Reimplement name-filtering

The filtering of items has not been implemented yet in
the KFileItemModel of the new view-engine. The patch brings back
this functionality again, but some minor issues are open:
- When filtering trees expanded directories should only get
  hidden if no child is visible
- Regular expressions are not supported yet (they have not been
  supported in Dolphin 1.x but it is now quite simple to implement).
- When filtering previews and removing the filter it might be
  possible that the preview is not shown (is most probably an
  an already existing bug in KFileItemModelRolesUpdater).

BUG: 287642
FIXED-IN: 4.8.0

Now somewhat works, but with a big nurmber of files crash.

I attach another related crash, a segfault happening when click on a element of the places widget after filtering a folder:

Comment 6 Peter Penz 2011-12-04 17:22:28 UTC

Git commit 857f3dda17195f01798fd082802e8c43c4d098a0 by Peter Penz.
Committed on 04/12/2011 at 18:16.

Fix crash #1 when filtering items

When filtering items it was possible that the current index got
an invalid value which resulted in accessing the URL of a
null-KFileItem.

There is still one (general) open issue in KFileItemModelRolesUpdater
(crash #2) where a KFileItem that is already null gets read.
It is not really related to filtering but can be triggered
quite easy when filtering huge directories with enabled previews.

CCBUG: 287642

Fix crash #2 when filtering items

When KFileItems get removed from the model it is temporary possible
that the pending items are still part of the KFileItemModelRolesUpdater
while they have already been removed from the model (this happens
in the context during the signal itemsRemoved() gets emitted).

Comment 10 Peter Penz 2011-12-04 19:51:52 UTC

@Manuel: I could not reproduce the crash anymore with the recent fix, but it is of course still possible that I might have missed something. Please just reopen the issue again if you still can reproduce it. Thanks for your support!

Comment 11 Manuel Tortosa 2011-12-04 22:24:08 UTC

Seems fixed. Will recheck the next beta/rc. thanks.

Comment 12 bill p. (aka google01103) 2011-12-11 11:41:40 UTC

appears fixed in 4.8rc2, though the visual affects seem weird when filtering
