Bug Description

Binary package hint: python-fuse

The Python FUSE bindings have a deadlock bug on fsdestroy. I have observed this in Hardy with python-fuse version 1:0.2-pre3-4ubuntu1. This has been fixed in the upstream CVS, available from http://fuse.sourceforge.net/wiki/index.php/FusePython , specifically in revision 1.21 of the file /python/fuseparts/_fusemodule.c .

There are a relatively small number of changes currently in upstream, it would probably be best to synchronize. However, I have posted what I think is a sufficient patch to fix the immediate bug.

I just requested the sync from debian unstable, which has the fix. I'll mark it as fix released once the packages is synced in intrepid

As of (at least) 2:0.2-2 this bug is back. I checked out the source and compared to the patch, and this fix has not persisted. Experiencing deadlock on fsdestroy in Lucid using python-fuse 2:0.2-2

I applied the patch that Dave posted above, and it fixed the issue (again). The upstream version 0.2.1 from http://fuse.sourceforge.net/ also has this change applied, so there should be no problem. It just got reverted somewhere along the line.

Daniel: The patch you refer to is present in maverick, so we can provide a fix in lucid via https://wiki.ubuntu.com/StableReleaseUpdates

I've prepared an SRU, attached, and uploaded to lucid-proposed, pending approval.

Accepted python-fuse into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

Please note that this bug should not have actually affected pytagsfs as I had implemented a work-around (cleaning up at the end of main(...) instead of using fsdestroy).
