subversion 1.6 hanging when used with gnome-keyring 2.28

[Ben Hall <bh...@wetafx.co.nz>]

Hi all,

I've encountered a problem whereby svn operations to an authenticated
apache2 server are hanging indefinitely.

It happens erratically but often enough that it's normally reproducible
within 20 operations.

I'm using ubuntu 9.10 on the client side.

I've reproduced this with subversion 1.6.4, 1.6.5 and 1.6.9 in
conjunction with gnome-keyring 2.28.1 and 2.28.2.

I've tested against two different apache2 servers (2.0.52, 2.2.3).
It doesn't appear to be server related though. I packet traced during
the problem and the last response from the server is an authorisation
request. There is nothing further from the client at that stage.

Here is a gdb backtrace from svn 1.6.9 from where I was able to trigger
the problem after 13 consecutive 'svn ls' commands. It appears to be
waiting indefinitely for gnome-keyring.

Any help would be much appreciated.

Yes, it's definitely unlocked. I did not ignore the dialog. I clicked 
'Allow Always'.

keyring_tool --info reports the following:

Keyring locked : no
Auto lock on idle : no
Auto lock idle timeout : 0 (in sec)

I can reproduce this by simply running 'svn ls' against a repo in a loop.

Thanks,

Is your gnome-keyring unlocked? If not unlock it first. Ideally, there is a 
gnome dialog which is thrown up after unlocking, saying "Allow Access to 
keyring" where you can say allow once, always, etc. May be you ve ignored this 
dialog or there is some problem in opening this up.

Thank You.
