[Catacomb] fixed -- mod_mime.c#find_ct() redux

It looks like Catacomb (0.8.0 is what I just downloaded) is doing the
same thing in its dav_repos_set_headers as mod_dav_svn. That hook
runs after the fixups hooks, so it just trounces on the content-type
that mod_mime tried to set with ModMimeUsePathInfo.
Ah, good call. I've fixed Catacomb to not do this anymore unless the
RDBMS has Content-Type defined.
In doing some debugging, with mod_dav_fs (with DEBUG_GET_HANDLER
repos.c) I've found that find_ct is not called to identify the type. I'm
Well, here, find_ct is called in the fixups stage. So, I'm not sure
what's going on for you. Some more specifics could be helpful.
I think because content_type was already defined, it skipped calling
assuming the inability to run PHP scripts from a DAV server is the same
problem. Bug or feature?
Note that since PHP 4.2.3, which (I believe) introduced the PHP
handler for httpd-2.0 and removed the PHP filter, it's not possible to
do this chaining. Implementing PHP as a filter got to be a nightmare,
and we eventually gave up and did it as a handler instead. One of the
drawbacks is that PHP can't work off of virtual repositories or
anything that has its own handler now.
(PHP requires file-backed input into its parser which kills it for
Subversion and httpd-2.0. I believe there may be some work to allow
PHP to take in push-based streams like Apache httpd output filters can
deliver - when that is ready, we can reexamine PHP as filter again and
determine what needs to happen on httpd's side to make it all happy -
there is definitely some work that has to be done to httpd as well.)
This is a major issue with non-fs backends...One option would be to
re-do the filter to use a temporary file to feed to PHP (a gross hack, I
know.) Thanks for the details/history...
Also, I would highly recommend that testing of Apache include testing
GET handler in mod_dav_fs. There are other backends (Catacomb, ?)
mod_dav as their front-end and who handle GETs themselves and we're
into these issues.
httpd-test's perl-framework already has some tests for WebDAV that
does exactly this. Feel free to help us expand our tests over on

Strangely, I am not seeing the problem with mod_dav_fs anymore...Perhaps
I was hallucinating...I guess it "works for me". :^o
Good news is I now have a much firmer grasp of the internal workings of
Is there an active project to write/improve the documentation of these
