Seems unneccessary to support since javascript should be able to access
the file that the user has selected to upload, and PUT its content to the
presigned url.
In the P2P protocol, PUT can proceed and at the end the client can indicate
the content changed while it was being sent by sending INVALID. This is
necessary to support unlocked files. Extending the P2P protocol to support
indirect upload to an url needs to somehow also handle this case. One way
that would work is to never upload unlocked files to a presigned url.
Instead send the content of those via the P2P protocol the usual way. Only
send locked files to the url. But a file can also get unlocked and then
modified while it's being sent, so can git-annex, as a client, ever send
any files to a presigned url? Maybe this feature would only ever be useful
in cases like OpenNeuro's, where something other than git-annex is
communicating with the git-annex proxy. Alternatively, allow the wrong
content to be sent to the url, but then indicate that with INVALID. A later
reupload would overwrite the bad content.
