Update working copy from hook script

[Tyler-54]

I'm trying to update a working copy by having svn update executed during a post-commit script after the repo has been committed to by another wc. I have a script that executes svn update, but it only works when I run it directly in the command line. It gets an error and stops when the hook script is called automatically by svn. I'm executing "SVNPATH/svn update fullPathToWC" but I'm not sure why it only works from command line.

It's probably filesystem permissions.  The hook runs as the user the  
server is running as and that user must have read/write access to the  
wc path being updated and EVERYTHING within it.  Check your permissions.

Is the user you're referring to the same as the svn author? I did a svnlook author command and it returns the same as when i execute from the command line.

Otherwise, I'm not really sure where to look to change file permissions. SVN is being run by Apache on a Win2k server.

You realize the the hooks are executed on the server machine and not
the client. This means that hooks do not have access to the user's
working directory where the original "svn co" took place.

Are you, by chance, executing your script on the client's machine
logged in as the client? That may be why your script works, but not as
a hook script.

That's why there's the "svnlook" command. It allows you to examine
various files without having a working copy.

No: the user the server-side working copy is owned by, which should be  
the user your Subversion repository is served by...

...which will be the user your Apache server is running as. On Linux  
this could be "nobody" or "www" or "apache"; I don't know what it will  
be on a Windows server.


Another likely candidate is that you have not specified authentication  
details, e.g. with the --username and --password options. When you run  
the script yourself, it uses your cached credentials, but your Apache  
web server probably has not been a Subversion client before and so  
doesn't have any credentials cached.

More generally, you need to direct both the stdout and the stderr of  
the svn command in the script to some useful place, like a log file,  
so that you can find out exactly what's going on.
