Subject: listen: Fails to start with home over NFS

Date: Wed, 01 Nov 2006 20:46:53 -0300

Package: listen
Version: 0.4.3-1
Severity: grave
Justification: renders package unusable

When home is mounted over NFS, listen fails to start with the following
backtrace:

starts normally.

Hi,

Thank you for your report. I have forwarded this upstream as it is a bug in the core engine of listen.
As I have not the possibility to test home over NFS, I will surely ask you kindly to test workarounds proposed by upstream.

Cheers,
Julien

I've got home over NFS (actually, _everything_ over NFS) and listen starts
perfectly for me (both first and subsequent times). I've tested on two
different machines against two different servers, and no go... Are you sure
this is really the problem in question?

What I am sure about is that setting HOME environment variable to a
directory not located over NFS and then executing listen does not get me
that error. And I have setups where my home is not over NFS and listen
works OK.

Two different setups (one, in fact, was Ubuntu, the other, Debian
unstable) where home was over NFS gave me errors related to pysqlite.
Perhaps, we could try a simple pysqlite code that can give this same
error.

Or perhaps there is something about our NFS server setup. Mine was using
the kernel server, because it has lock support (and its lack would be the
first thing I would point as the reason for the errors).

Any tests I can try? The setup is on a lab which I may have some remote
access (I will not be there until next week).

Regards,
Thadeu Cascardo.

What happens if you first move away your .listen directory? It's entirely
possible that yours became corrupt for some reason and mine didn't.

I'm using the NFS kernel server, too. I don't think anybody uses the NFS user
server anymore; it hasn't been developed for years either.

In general, I'd try to isolate if this is a feature of your NFS setup in
general, or your specific .listen directory (probably media.db). What happens
if you copy the .listen directory to somewhere on non-NFS, set $HOME to that
place and the run listen? Also, does this happen _every_ time or can you run
listen a few times before the database goes bonkers? You don't access the
database from multiple hosts at the same time, do you?

I could not run listen one single time while HOME was over NFS. I may
try these (removing .listen and trying it again over NFS and moving
.listen to a non-NFS filesystem and running listen over ther), but I
don't think there would be any results. As soon as I do these, I'll post
again with the results. Since I have a second machine now, I may even
try this at home (no pun intended) and see if I get the same results.

Thadeu Cascardo.

Hi,

I have been able to launch listen with home over NFS (tested with NFS
server in both Sarge and Unstable, with both clients in Etch and
Unstable).

Please try the proposed tests to check if your .listen is corrupted or
not.

Thanks for your help
Cheers,
Julien

Since nobody else can reproduce this, I've been given permission from the RMs
to downgrade the bug.

Hi,

WRT this bug, do you have any news?

Can you please detail your NFS setup so that we can try reproducing the
bug?

With no answer from you, I will close the bug.

Hello,

I've just tested it on a different setup. Instead of getting the same
error as I've got before, listen simply takes forever to start.

This time I've tried harder to fix it. Installing nfs-common in the
client solved the problem. I was able to start listen with home over
NFS.

Would this be worth a note in README.Debian?

Thanks,
Thadeu Cascardo.

Urm, if you don't have nfs-common installed, I'm surprised you can mount NFS
shares at all. I'd simply close this with "user error"; it's a basic
misconfiguration which has nothing to do with listen.

Hi,

Given the new elements, it seems the issue has nothing to do with listen, and 
I am thus closing the bug.

Feel free to re-open it if you are absolutely sure it is a problem in listen.

Julien
