Hi, i'v been trying to reproduce this problem but with no luck. Could you add
some more info, steps or what ever what could help us to reproduce this. Thank
you.

There are no specific steps to reproduce this - Media Player in my n800 doesn't
scan card. I put card in internal or external slot, file manager see the card
and all in it, i can play mp3 files by clicking on them in file manager and
they're played by media player, but there is no files in Media Library - Media
Player somehow doesn't scan my card or something. How can i add debugging to
Media Player operations?

some info on this problem: i've installed Maemo Music Player Client, and if i
understand it right, this client must connect to some daemon to localhost:6600
- but he doesn't connect to daemon. tell me, how media player should find
music? via some daemon? i have ssh access to tablet so i'm ready to give you
output of any command (that would run in tablet). for now here is "ps ax":

What is the exact name of the card?

Comment 5 Eero Tamminen 2008-06-25 12:19:27 UTC

All the daemons used by the media player seem to be present:

on one side it says 

Transcend MMC 1Gb

on the other these digits: 

110450 1385
6330 AB 1G 0504


i wrote a simple script, that do 'rm /home/user/.meta_storage && killall -HUP
metalayer-crawler'. when i run it - crawler starts scanning and further
everything is working fine.

Comment 7 Eero Tamminen 2008-06-27 14:55:18 UTC

Related to bug 2213.

Isn't it enough just to kill the crawler so that it's restarted?

(If not, it would seem like the metadata database had somehow corrupted)

no, it is not enough. i don't think that metadata database corrupted - after i
run this script, metacrawler scan cards and voila - media player see all those
files on my card and everything work as it should.

How do you re-produce the issue after this?  Eject and re-inject the card?

well, i delete something on a card and write some new music into a card,
whether doing this via usb or via cardreader (with card ejecting and
reinjecting into n800) - and metalayer-crawler doesn't see new files - until i
run my script.

Comment 11 Eero Tamminen 2008-07-01 16:00:09 UTC

Only reason for this we could come up with would be file system being full
or the database (or its journal file) for some other reason being not writable.
What "df" tells about the free space the rootfs?

(normal user cannot fill it completely and crawler is run as normal user)

how can i debug what metacrawler do? does it have some command-line switches or
something? i'm familiar to unix, so i can help you here.

Ok, rootfs being full is not the problem.

Install strace or ltrace as described here (see bottom of the page):
  http://maemo.org/development/tools/

Then strace e.g. the file operations that crawler does:
  strace -e trace=file -p <crawler PID>

Both when it works and when it doesn't work.  If file ops don't
reveal anything, strace everything (remove -e option).

i've added to /etc/init.d/metalayer-crawler0 to starting case "-c /media/mmc1"
and metacrawler scan my card with no scripts and deleting .meta_storage.

Comment 15 Andre Klapper 2008-08-01 15:30:12 UTC

Alexander, any news here?

(In reply to comment #15)
> Alexander, any news here?

sorry, i was a kind of busy. 

yes, news - today i've upgraded to diablo, and metacrawler still doesn't see my
files. will try to trace.

Comment 17 Andre Klapper 2008-09-22 16:35:04 UTC

After last weekend's Maemo Summit, it's clear that Nokia is working on an Open
Source replacement for metalayer-crawler based on Tracker, so this bug is
obsolete/invalid for Fremantle.
Hence I also don't expect much Metacrawler bugfixing for Diablo anymore, to be
realistic. This might be frustrating for Diablo users, but ressources are
unfortunately limited.

I'm going to close this report as WONTFIX for Diablo (and INVALID for
Fremantle) soon if nobody has strong objections.

I've the same trouble on a N810 with OS 5.2008.43-7. I removed
/home/user/.meta_storage but it doesn't help. I restarted the device but
nothing changes. If I open a media file by clicking it on File Manager
everything I can reproduce it, but I wasn't able to refresh the Media Player
library.

I realize that it was another problem. The metalayer-crawler process never
starts, and when I tried to start it manually I get a Segmentation Fault. It
seems not to be related with this bug.

Could you file a separate bug about it and add me to CC?  You could then
install "strace"[1] and strace the crawler when it starts and if that doesn't
tell enough, install "sp-rich-core"[1] and attach the core dump of the crawler
process to that bug.

[1] From the SDK tools repository, see:
    http://maemo.org/development/tools/

(instructions for enabling the repo are at the end of the page. Unlike the main
SDK repo, it should be safe to keep this enabled also in the device.)

Comment 21 Andre Klapper 2009-03-26 18:19:44 UTC

The closed source component metalayer-crawler will not receive any bugfixes
anymore and is deprecated, hence this bug report is WONTFIX.
Fremantle will use the open source component Meta Tracker instead which is
already available in the (unstable) Fremantle SDK releases.

Note that there is a request to open-source the source code of
metalayer-crawler: bug 4082.
