RE: Setting up the Configuration File

Okay, I now know that I can't setup a config file for a server in order to
make sure that the svn:keywords property is set.

However, I've been playing around with the pre-commit hook, and have come up
with the following little tidbit of Kornshell code which looks at all the
files that are being changed, and checks the svn:keywords property to see if
it is set:

svnlook changed -t $TXN $REPOS | while read type path
do
    prop=$(svnlook propget -t $TXN $REPOS svn:keywords $path 2> /dev/null)
    if [ ! $prop ]
    then
        print -u2 "No property svn:keywords is set for $path!\n"
    else
        print -u2 "Keywords property is $prop"
    fi
done

This means I can prevent someone from committing their changes if the
svn:keywords property isn't set for a file. I could even give the command
they need to run.

However, what I'd really like to do is set the svn:keywords property for the
user, but I can't figure out how to do that. The commit script is running on
the server and not on the client who has the working directory checkedout,
so I can't do an "svn propset". But, neither svnadmin nor svnlook allow me
to set a property.

I'm pretty new to Subversion and might be missing something fairly obvious.
Is there a way for the server to "fix" this transaction and set the
svn:keywords property for the user?

As far as I know, there is no way to direct enable-auto-props to a
specific repository.

The 'config' file is a user configuration file that configures the
behavior of the svn client, not the repository. /etc/subversion/config
sets defaults for all of the clients local to a given machine, but that
default can be overridden by each individual user's ~/.svn/config file.

There really isn't any good way to do what you want to do. One
possible hack would be to give all of your users a special script for
doing file adds that would wrap the 'svn add' command and automatically
perform the property addition if the file is being added to project1.
It would be a bit of a pain, since you'd have to distribute special
scripts/binaries to each user, and it would also be a little bit
error-prone, since users would still be able to use 'svn add' by
itself. If you really need the auto-props differentiation, though, it
may be a workable solution.

Hope that helps,
