Two releases of the Haskell DAV library today. First release had my changes from yesterday. Then I realized I'd also need support for making WebDAV "collections" (subdirectories), and sent Clint a patch for that too, as well as a patch for querying DAV properties, and that was 0.2. Got it into Debian unstable as well. Should have everything I'll need now.
The webdav special remote is now working! Still todo: Encryption support, progress bars, large file chunking, and webapp configurators. But already, it's a lot nicer than the old approach of using davfs2, which was really flakey and slow with large data volumes.
I did notice, though, that uploading a 100 mb file made the process use 100 mb of memory. This is a problem I've struggled with earlier with S3, the Haskell http libraries are prevented from streaming data by several parts of the protocol that cause the data to be accessed more than once. I guess this won't be a problem for DAV though, since it'll probably be chunking files anyway.
Mailed out all my Kickstarter USB key rewards, and ordered the T-shirts too.
