directory cache on the 80gig ipod

[psycho_maniac]

every other time i run rockbox on my player the directory cache loads and then i go to play a file and then the directory cache just turns off. i am running a current build and did chkdsk/f and i disabled, rebooted, enable, let scan, then rebooted, since my "fix." and it still does. it. anybody else having this problem? these screendumps are taken within a minute

Try seeing if having less files on your player causes the problem to stop.

I am having this problem as well.  Earlier I was just annoyed with the fact that my ipod would have to scan the disk every other time the player was turned on but I have learned to live with that and chalked it up to the ipod just not knowing if any files have been added since last time it was turned on.  

Now however I have discovered that just about every other boot of the player, the dircache does not work period, exactly like you have described.  I do not know if it works before a file is played because I have my player set to resume play, so I just always notice it not working from the boot.  It seems that whenever rockbox scans the disk upon turning the player on is when dircache works.  The times it does not scan the disk are when I notice dircache not working.

I also have a large number of files (>10k).

ah ha im not crazy !!. i am currently removing unnecessary files  that i dont need on my  player and going to see if i can get to at least 8k songs. I think GodEater has 8k files i think and he said he does not have this problem.

Alright I have less then 6000 songs on my player and this problem has stopped. squidkidd, Could you try this also? Thanks. and then after you remove some songs then disable dircache , reboot, enable dircache, let scan, then reboot again. this will fix it.

this will fix it.

Once I ever get some free time I might see if this works, though I don't see how this fixes it if it still does it with a large number of files on the player.  Is this a bug, does it need to go on the tracker?

well ive been turning my ipod off and on all day today and dircache has been working every time.

[squidkidd]

Are you saying that after removing a bunch of files and getting dircache to work normally, it should continue to work after putting a large number of files back on the disk?

[psycho_maniac]

no no. i still have 6k files on my player. i think somehow maybe if you have over 9k of files this breaks the dircache feature?

I think I had a similar problem a while back. I only have a H120 (20gig), but I had over about 8k files on it when I kept a few backups of the .rockbox folder around. Each .rockbox folder is about 700 files. I zipped my backups and the problem was gone.
That's not a solution if you want to listen to that much music, though.
You can remove a few wps and fonts that you don't need from .rockbox so that you can have a few more music files.

Alright I have the logf enabled build. i would assume that i dump logf? this is what i got. i hope this helps. it seems that it always logs everything so i will give this and tell me if this is correct.
here is the logf when the dircache doesnt work http://pastebin.ca/727390

Something like this seems to be happening here (in a somewhat simplified way):

• Dircache scanning starts in the background.
• At least three files are opened for writing.
• Dircache scanning completes.
• The third (or later) file opened for writing is written to or closed.

Looks like a bug to me, but I'm not yet sure what the proper fix is. Some input from Slasheri would be nice.

[psycho_maniac]

I found another work around. set the start up screen to menu (meaning dont let playback start automatically), let the dircache build when it takes longer (this called a background check? ),  when its done start playback and it will work. this seems to work for me.

[squidkidd]

That seems to work here as well, though it is far from a practical workaround, as its hard to know when the build is done while you're driving.

I noticed that this problem does not exist anymore. No idea how it was fixed. At least i think its fixed. Also i noticed this problem does not happen on the gigabeats as i have the same amount of files on my gigabeat Can anybody else confirm this on the ipod?
