There are actually two versions in this patch, one of which requires twisted.web2 and the other of which uses the Python standard library's socket module. The socketish one doesn't know when the web server is done so it hangs after doing its thing. (Oh -- maybe I should add an HTTP header asking the web server to close the connection when finished.) The web2ish one works better in that respect. Neither of them handle error responses from the server very well yet.
After lunch I intend to finish the socketish one.
To try one, mv src/allmydata/scripts/tahoe_put-{socketish,web2ish}.py src/allmydata/scripts/tahoe_put.py .
If you want to try the web2ish one, and you can't find a web2 package to install, you can get one from:
