git-svn dcommit and setting svn properties

Hi,

My internal subversion repository has a pre-commit script that requires the svn:mime-type and svn:eol-style properties to be set on any new file before it can be added to the repository. If these properties aren't set, the commit fails. When using git-svn dcommit to commit a patch that adds a new file, the dcommit also fails with the error below. I have added auto-props rules in my ~/.subversion/ config file to automatically set these properties based on file extension, so an svn commit doesn't require explicitly setting them. I tried adding the --config-dir=~/.subversion option to the dcommit command, but it didn't seem to make a difference.

Is there any way to set these properties or consult subversion auto- props so that git-svn knows how to set them during the dcommit? Would it be difficult to add this capability if it doesn't already exist?

Example command and subsequent error:

# git-svn dcommit --verbose --config-dir=~/.subversion
Committing to https://svn/repo/foo ...
         A       bar.c
A repository hook failed: MERGE request failed on '/repo/foo': 'pre- 
commit' hook failed with error output:
/svnrepo/hooks/check-mime-type.pl:

foo/bar.c : svn:mime-type is not set

     Every added file must have the svn:mime-type property set. In
     addition text files must have the svn:eol-style property set.

     For binary files try running
     svn propset svn:mime-type application/octet-stream path/of/file

     For text files try
     svn propset svn:mime-type text/plain path/of/file
     svn propset svn:eol-style native path/of/file

     You may want to consider uncommenting the auto-props section
     in your ~/.subversion/config file. Read the Subversion book
     (http://svnbook.red-bean.com/), Chapter 7, Properties section,
     Automatic Property Setting subsection for more help.
