Alt-F rc2 minidlna/Inotify

[Stealth]

Hello

I upgraded my 323 with success, but I'm seeing an annoying problem, I can't use minidlna with inotify.
There is inotify with Alt-f ? Or maybe minidlna is not compiled with ?

For my usage Minidlna is unusable without, because the rescan take a very long time each time I'm just adding a file

Thanks

[Keon91]

please check your minidlna.conf under /etc

mine contains:

# set this to no to disable inotify monitoring to automatically discover new files

# note: the default is yes

inotify=yes

and:

# notify interval in seconds. default is 895 seconds.

notify_interval=900

so every 15 minutes minidnla will scan for new files.

maybe you didn't wait 15 minutes?

Hi keon91

Unfortunately my conf is right, inotify works for you ?
I can see all my movies but there is no auto refresh (after many hours)

I'm using Alt-F fresh install, with minidlna "official" package, perhaps I forgot some dependencies ( I also installed kernel-modules without more success) ?

Thanks for your help

Maybe this can help you :

minidlna is compiled with inotify support, but it might not be working.

You can increase the log verbosity setting "log_level" in the configuration file, in order to check it.

I remember to see inotify reports in the log and after manually adding a file to the media folder.

I don't understand the need to have a "notify_interval" when inotify is enabled. Enlight me: will a full re-scan happens when the notify interval elapses? independently of the "inotify" setting?

The link http://forum.excito.net/viewtopic.php?f=9&t=3410 seem fix the problem

All works good

Just for information with my usage (minidlna, ligthppd, openssh, samba)  ALt-f is more fast than dlink's firmware and ffp 

Thanks for your work

I think you are right there is no link between
"notify_interval" and inotify
There is only a full rescan, if and only if, I
restart minidlna with -R or when I remove the db file

I thought there wasn't any inotify in Alt-F as it was not compatible with the glibc that is used.

Now, note this is coming from someone who has NO idea about these things, but I was having trouble with forked-daapd remote which would not do a pairing completely and I thought the conclusion reached was that inotify was necessary and this was not possible in Alt-f.

Ok, I found my post

-------------------------

I had posted there a year or so ago and the main guy had suggested that the use of uclib rather than the standard large libraries was probably a problem due to use of events, he suggested fdtimer (?) as a possible problem area.

-----------------------------------

I don't know if inotify would be what was meant by 'events', so maybe not related.

No, I don't agree, now minidlna works perfectly - with inotify - for me

Alt-F has 'inotify', the fdtimer event is unrelated.

Hi all,

If you are using mindlna with a large database, I found a trick that can save a lot of ram (for better response time for another applications)
This command - ulimit -m 400; exec minidlna - force minidlna to use only 400 ko by process, so there are much memory free
For the moment it's just a test but I saw no performance degradation for minidlna

You can show the limitation like this

pidof minidlna
642 640 639

more /proc/642/limits

For the moment I don't find a way to show a process swap usage in Alt-F
