Hello all,
I have a very strange problem with subVersion Hook scripts under Ubuntu Linux
(Ubuntu 12.04.4 LTS (GNU/Linux 3.2.0-64-generic x86_64))., when accessing the
repository via Apache2 WebDav. I'm using subversion 1.7.9 .
The WebDav Configuration is as follows:
<Location /sbox>
DAV svn
SVNPath /var/subversion/repos17/sbox
AuthType Basic
AuthName "Subversion Sandbox Repository"
AuthUserFile /etc/subversion/etc/svn-auth-file
Require valid-user
AuthzSVNAccessFile /etc/subversion/etc/svn-acl
</Location>
I tried with a post-commit hook (I wanted Trac to be informed about commits :
/usr/bin/trac-admin /var/lib/trac/YourProject changeset added "$1" "$2") but
the same problem occurs also for all other hook scripts, no difference what I
use as content of the script.
Let me explain my problem:
I used a Tortoise Client on a remote Windows machine and tried there a commit.
I always got the error message:
Failed to start '/var/subversion/repos17/sbox/hooks/post-commit' hook
I tried all possible changes at my hook script and at the end it consists only
of the following two lines:
#!/bin/sh
/bin/echo "Dies ist ein Test fuer Pre-Commit."
But I got still the same error message.
The execute bit was set for the script and the file owner was www-data .
A local call of the script works perfect:
sudo -u www-data env - ./post-commit /var/subversion/repos17/sbox/ 175
When I do a direct commit on the subVersion server (without apache Dav access:
) the post-commit script works fine. I could verify this because after such a
commit, the Trac shows the new changeset.
The very strange thing was, that when I did the tests yesterday the hook script
(even called via Apache DAV from Tortoise at a remote client) sporadically was
executed but it also failed sporadically without any changes in the script.
I checked in google for similar problems and the only helpful hint I found was
an entry from 2008 :
http://www.wandisco.com/svnforum/threads/31927-Hook-does-not-work-%28and-yes-absolute-paths-are-used-*g*%29;
: The reason for this was, that the system only has limited resources
available, such as main memory.
After reducing the number of server processes and/or threads created by Apache
at startup, the SVN post-commit hook worked fine when committing to the
repository. )
I restarted apache service but it didn't help. Also a reboot of the complete
machine did not help. htop showed that memory is still available:
Mem : 125 /3954 MB
Swp : 65 / 3068
I checked also the apache log but I found no relevant error message, even when
I used LogLevel debug in the apache2.conf .
Can you please give me any hint what is wrong.
Can I see in any log /trace why the hook script can not be started?
Thanks in advance.
Best regards Michael
