web_dav/Apache/Subversion

[John Peacock <jp...@rowman.com>]

A thought just occurred to me, but I have been unable to confirm or deny that it 
is possible:

I'd like to (on my test server only) have Apache use the subversion repository 
itself as the DocumentRoot.  This would mean that the test server would not have 
a WC of it's very own (that I'd have to keep updated with post_commit).  The 
files would be read-only (as far as Apache was concerned), so no autoversioning 
issues.

It would be sweet if I could simply commit a change to the repository and have 
the file immediately available to the [test] web server.  This is slightly 
different from enabling repository browsing within Apache.  I'd like Apache to 
just serve up the files directly out of Subversion, as if this were an ordinary 
filesystem.

Is this possible with Subversion's DAV support???

Sorta.

At the least, I think you'd have to use:

UseModMimePathInfo on

This allows the mod_mime filters/handlers to kick in.  Otherwise, it'll 
ignore it and none of your directives will be in effect.  svn:mime-type 
only sets the CT, but doesn't allow the filters to be inserted based on the 
filename.

I think there used to be a bug in mapping the repository to /, but ISTR 
that might be fixed.  It shouldn't be difficult to do so.

<Location />
  SVNPath /path/to/repos
</Location>

The other comment is that you'd need another <Location> block to actually 
commit to.  ModMimeUsePathInfo doesn't play well with DAV or DeltaV.

I think the best way to do this is write a little script (in 
PHP/Python/Perl/Apache module/whatever) that takes the request and maps 
it onto a repository resource.

Otherwise you might have difficulty getting index.html to be used for 
directories, and so on.

PHP example (/htdocs/repos.php)

<?php
     /* This script is totally experimental: I typed it directly
        into this e-mail message without testing.
        You need somehow to get this to run for every request, e.g.:
        ErrorDocument 404 /repos.php

     //TODO: some other checking of arguments?
     //TODO: if a directory doesn't contain index.html, you'll get a
     //      404 error.

     /* name is the URI requested. */
     $name = $_SERVER['REQUEST_URI'];

     /* if a directory is asked for, append 'index.html' (if a directory
        with the trailing slash is asked for, mod_dav_svn should give a
        response redirecting to the directory with a slash appended. */
     if (ereg('/^, $name))
         $name = $name . 'index.html';

     /* internally redirect to mod_dav_svn. */
     virtual ('/repos' . $name);

     //TODO: return value?
?>
