Subject: amule: share directory on external disk isn't persistent

Date: Fri, 30 Apr 2010 14:54:09 -0400

Package: amule
Version: 2.2.6+debian0-7
Severity: normal


I have a directory of files that I want to share on an external, USB disk (it's
on LVM, in case that's relevant).  I set the directory from Preferences /
Directories / Shared, and it seems to work, but when I unplug the disk and
later replug it, the directory is no longer present, and I have to once again
manually enter the directory by navigating the file tree.

Absolute correct. When you delete a file, it's being removed from shares 
on next access, same applies for deleted dirs and unplugged USB-Discs. 
Otherwise you'll get a file not found message on every access, which 
would be worse. We could keep the entry for the dir you mount the disc 
in the list and just ignore it, which would cause the list of shares to 
grow. In this case every deleted file or dir will stay in there, and 
startup would take longer and longer because they have to be checked all 
to see if they reappeared, and most likely they would be rehashed to see 
if they are still the same file.

Just don't unplug the disc while aMule is running, and everything is 
fine.

Thanks for the explanation.  But the disk is not always available, and
I sometimes want to run aMule when the disk isn't there.  In such a
case, isn't the directory still deleted?

Perhaps there could be some sort of option to mark certain special
directories as 'persistent', so this way we could have the best of both
worlds.  Ordinary files and directories will be automatically removed,
to avoid the problems you mention, but some basic share directories
could be allowed to remain, to avoid the user having to reenter them
frequently.

Regarding the problem of having constant 'file not found' errors,
there's anyway a "Reload shared files" button on the shared files
page.  Why not just mark any files or directories not found as
'inactive' or something, and recheck them when the user hits that
button?

Thanks again, and thanks for your Debian work in general,
Celejar

Exactly.

This would need a change of the config file, which isn't used only by 
aMule. We don't care much about the mods out there, but emule has to be 
able to read these files, too. Beside the fact that there is a change 
for the gui needed to implement this, and these files are still locked.

The problem with this is, that only dirs are shared. We don't care about 
single files in this part of the source. The easiest way for you is to 
just insert the dir, when you plug the disk in.

echo "your-mountpoint" >> ~/.aMule/shareddir.dat and then reloading the 
shared files should do the trick. With the right udev-rules you can 
automate this, too.

Hm, I see now that I'm running aMule, having started it without the
external disk plugged in, after having previously shut it down while
the external disk had still been plugged in, and the directory from the
external disk actually has remained in the shareddir.dat, even though
the directory doesn't exist currently on disk, and it stays there even
after I hit 'reload shared files'. Does it actually only get removed
when the disk is pulled while aMule is running?

The 'echo' is simple enough, but I suppose there's no way to script
the 'reload' command?  [The manpage doesn't indicate that amulecmd
can do this.]

Iirc, the files is read on startup and written on shutdown.

Unfortunately this is a feature of svn. With the stable series this 
click has to be done by you.

Whenever I do this, the new directory gets appended to the last entry
in the file, without a newline separating them, which clobbers both
directiories, e.g.:

/home/user/.aMule/Incoming/media/storage/user/dir

I assume that the problem is that when aMule removes dead directories,
it also removes the last newline.

I don't know if you're allowed to change aMule's behavior in this
regard, but if you can't, then I'm just noting here, FTR, that the echo
command needs a newline before the new directory.

Thanks.  Yes, I did figure out how to do that, but I just wanted to
note FTR that it's required, and that the echo command given in an
earlier email isn't quite correct.

Upstream agrees with what Werner said, so closing this report (since
it won't change and a workaround was provided).
