I already sent an email to neon@webdav.org earlier today, explaining
the problem. Maybe it needs to be modded through, since I'm not a
subscriber. Here it is, reprinted. Should we keep both svn and neon
lists cc'd, if we're going to discuss it?


I'm trying to teach Subversion's dav layer to do LOCK & UNLOCK requests.

ne_lock.h looks like a wonderful API. But Subversion needs to both
send and receive custom HTTP headers in the request & response; it's
the only way to get a reasonable mapping between a Subversion lock_t
and a webdav lock_t.

Am I doomed? It looks like I'll have to reimplement all the logic of
ne_lock() manually -- including the XML response parser -- just so I
can send and receive custom headers.

Or is there some way I can get access to the ne_request object
directly, before and after the LOCK request is dispatched? Any clever
