Original Pull Request: https://github.com/sigoden/dufs/pull/417

State: closed
Merged: No

The specification of WebDAV (RFC4818) does not allow recursive creation of parent directories.

During MKCOL processing, a server MUST make the Request-URI an
internal member of its parent collection, unless the Request-URI is
"/". If no such ancestor exists, the method MUST fail. When the
MKCOL operation creates a new collection resource, all ancestors MUST
already exist, or the method MUST fail with a 409 (Conflict) status
code. For example, if a request to create collection /a/b/c/d/ is
made, and /a/b/c/ does not exist, the request must fail.¹

The feature to create all parent recursively when uploading, moving or copying a file has been removed and instead a check has been introduced to see if the directory exists. If not, 409 CONFLICT is returned in accordance with RFC4818.
