4017	"WebUI: enhance ""put"" operations"	meejah		"Currently, the WebUI API for uploading a file (aka `tahoe put`) only returns when the file is uploaded to storage-servers.

This makes sense: your file isn't ""put"" into Tahoe until that happens. However, it makes progress information hard because the fine-grained progress API indexes operations by ""storage-index"" which you only learn after the HTTP operation that `tahoe put` uses is completely finished.

It's also not useful to show progress of the data-transfer: Tahoe accepts it quickly (usually this is via localhost) into a temporary area before doing erasure-encoding etc and uploading to storage-servers.

One approach could be a ""two-part"" API where you initiate the operation (i.e send all the data to your local tahoe client) and receive a handle of some kind. If possible, this could be the storage-index.

Then, a second API can be used to ""wait for handle X to complete"". Meantime, the existing progress information is used to determine the encoding and upload (to actual storage-servers) progress. (Note that this needs a storage-index currently)."	enhancement	new	normal	undecided	unknown	n/a
