Non-standard HTTP methods for view handlers (AKA WebDAV is b0rken) [PATCH]
--------------------------------------------------------------------------
Key: COUCHDB-815
URL: https://issues.apache.org/jira/browse/COUCHDB-815
Project: CouchDB
Issue Type: Bug
Components: Database Core
Affects Versions: 1.0
Reporter: Jason Smith
Priority: Minor
CouchDB prevents the new view server handler methods, _show, _update, etc. from
handling unknown HTTP methods. This prevents Couch apps from being able to
implement extensions to the HTTP specification or to add application-specific
methods to HTTP, violating the spirit of _show and _update.
For example, it is not possible to make a CouchApp WebDAV server because _show
and _list must support the PROPFIND method.
In couch_httpd:handle_request_int/5, the response from Mochi is coerced to an
atom if and only if the atom already exists (using
couch_util:to_existing_atom/1). That is an odd whitelist, to say the least:
$ curl localhost:5984 -X PROPFIND # Crashes mochiweb when to_existing_atom
throws badarg
curl: (52) Empty reply from server
$ curl localhost:5984 -X list_to_binary # Any atom works
{"error":"method_not_allowed","reason":"Only GET,HEAD allowed"}
Considering the cURL commands above, I filed this as a bug, not a feature. I
will explore some options and submit patches.
