post-commit hook fails

[Alien8 Recordings <al...@alien8recordings.com>]

Hi All,

I've scoured the mailing list and the web for info on why my post- 
commit hook might be failing. It seems to be a very common problem  
and most of the threads I read seemed to remain unresolved. In any  
case I am trying to do execute the following simple post-commit script:

---------
#!/bin/bash

REPOS="$1"
REV="$2"
/usr/bin/svnadmin dump /var/svn --revision $REV --incremental > / 
backup/svn_backups/dump$REV &> /tmp/postout.txt
---------

I am running svn with mod_dav through apache. I made the script  
executable to apache and the backup directory is owned by apache. The  
script works just fine when I execute through the shell, but when I  
commit nothing seems to happen. The stdout/err file is never written.  
Does anyone have any suggestion about how I could solve this problem?  
Am I missing something?

Thanks,
Sean

Hi Bob,

Thanks for your insight. The change actually worked to deliver the  
following error message:
/var/svn/hooks/post-commit: line 47: /backup/svn_backups/dump41:  
Permission denied

The svn_backup directory was owned by apahce, but the parent  
directory was owned by root and unreadable by all other users/groups.  
I chmod'ed 755 on the parent directory and now it's working. THanks!

Take care,
Sean

You make a typo.  The & puts the command in the background and the >
redirects the next command to the output file.  I think you wanted
"2>" here.  No need for >& to do synchronous updates since this is a
different file from fd 1.

Easier to redirect all output to a file for all commands.  See the
additional 'exec' line below for an example.

  #!/bin/bash
  exec >/tmp/post-commit.out 2>&1
  REPOS="$1"
  REV="$2"
  /usr/bin/svnadmin dump /var/svn --revision $REV --incremental > /backup/svn_backups/dump$REV
