[drakma-devel] [Patch]: better file-names when sending multipart/form-data from streams.

The attached patch does two things: * :filename option takes precedence of automatically determined names (it was the case previously only for pathnames, and not for streams or functions). * if stream is a file-stream, which means it's a pathname designator, use file-namestring to get the filename. -- With Best Regards, Stas.
