Hi, I have toyed around with kaa.beacon a little bit; this is really great stuff! It's an incredibly confortable basis for my movie database project because it automatically recognizes and indexes so many media types (discs, .avi, .ts, authored DVD directories on hd, ...) which is one of the great features I like Freevo for.
However, I have a lot of more or less small problems that I'd like to
report in the following:
1) beacon-search does not terminate properly (obviously hangs on
sys.exit), easily reproducable here even with --help.
2) beacon-search always finishes with this error when connected to the
daemon (e.g. with --info, --list-media, simple search):
2008-10-04 21:35:40,691 [ERROR] rpc(284): Socket closed before authentication
completed
3) since only /dev/cdrom is in /etc/fstab, and /dev/cdrom is symlink
to hdc, beacon-daemon reports:
2008-10-04 21:33:45,780 [ERROR] callback(192): mount: Konnte /dev/hdc nicht
in /etc/fstab oder /etc/mtab finden
3a) this is likely related; when I eject the disc, I am getting:
2008-10-05 18:40:48,940 [ERROR] async(391): Unhandled InProgress exception:
AttributeError: Exception raised asynchronously; traceback follows:

AttributeError: 'NoneType' object has no attribute '_beacon_id'
4) when I terminate beacon-daemon (using ctrl-C; I started it with --fg), I
got:

Beacon done.
(I have a DVD burndir with AUDIO/VIDEO_TS subdirs in the indexed tree
which may cause this?)
5) I have worked around problem 3 by modifying /etc/fstab and
replacing /dev/cdrom with /dev/hdc to be able to index discs. Then, I
have inserted a disc that I tried before, but although the media was
reported by --list-media, the movie from the disc was not in the DB,
so I wanted to --del-media in case the DB already contained a wrong,
empty list of contents. However, after --del-media, I am not getting:

prop['beacon.content'] = media['content']
TypeError: 'NoneType' object is unsubscriptable
Obviously, the DB has become inconsistent (at least from beacon's
POV)? Further indexing does not seem to work anymore; I am getting
the same traceback when I insert new media.
6) When I delete everything from ~/.beacon except 'config', and I
restart `beacon-dameon --fg`, I am getting kaa.beacon.root in
--list-media twice (IDs 1 and 2). Also, I am getting the same
--del-media behavior as in 5), so this is reproducable and obviously
not related to the former problem 3.
7) --del-media should support media names, not only integers; I have
tried to write a simple patch (attached) to do so, but it does not
work. This is very strange because it *does* find the correct entry
in the DB and the variable 'media' is set to the very same integer
value as if I had specified it directly on the command line, so the
only reason I see why this fails (it simply does not seem to do
anything) may be that `break`ing from the query loop:
for m in (yield kaa.beacon.query(type='media', media='ignore')):
does not clean up something, so that the db record is not properly
deleted?! I must confess that I never used this yield-syntax (or kaa
notifier, for that matter) before, so I may not fully understand
what's going on here..
