I had a brief conversation with some people on IRC tonight because my svn
import was failing. The error was:
subversion/libsvn_ra_dav/util.c:358: (apr_err=175002)
svn: RA layer request failed
svn: OPTIONS request failed on /foobar
subversion/libsvn_ra_dav/util.c:343: (apr_err=175002)
svn: The OPTIONS request returned invalid XML in the response: XML parse
error at line 1: Extra content at the end of the document
.. (/foobar)
Notice that a 301 request is a permanent redirect, and the reason for this
redirect is that I requested /foobar, not /foobar/. There are a couple of
problems with this.
1) The error message isn't very good.
2) I got this even if I put /foobar/ in my request. I haven't done
enough research to determine if my shell or the svn client was stripping
off the trailing slash, but something is. I tend to think it is the
shell.
3) This is a DAV resource and an OPTIONS request, thus it shouldn't be
subject to mod_dir's redirection.
The solution, luckily, is simple. Add the following to your Apache config
file:
BrowserMatch "SVN" redirect-carefully
This instructs mod_dir to only do the redirect on GET requests. That
should be mentioned in the docs somewhere.
I have copied the httpd development mailing list, because this bug was
specifically addressed over a year ago. I know, because I am the person
who brought it to Greg's attention last time too. Mod_dir should not be
redirecting non-GET requests by default.
