Is there a simple way to get the request_rec structure from the svn_fs_txn_t or apr_pool_t structures? Another thing that might help is where is the entry into mod_dav_svn for a HTTP PUT request?

You'll need to tweak the dav_svn__attach_auto_revprops() function's
signature to accept a 'request_rec *r' parameter, and tweak the callers to
provide it.

As for the entry point, mod_dav_svn is actually a DAV filesystem provider
that sits behind Apache's own mod_dav. In the Apache source code sits a
modules/dav/main/ directory, and the source code in that directory contains
functions with names of the form 'dav_method_REQUESTTYPE' where REQUESTTYPE
is the HTTP request method (in lowercase). So,
${HTTPD_SRC}/modules/dav/main/mod_dav.c:dav_method_put() is the entry point
into this whole stack of WebDAV-based version control.
