The core Wormhole exchange will retain a blocking/non-Twisted
implementation, but the file-transferring Transit class is going to be
Twisted-only (maybe Twisted+asyncio). I want to improve the
protocol (add more parallelism, reduce round-trips), and the blocking
implementation is a messy bundle of threads and ick.
When this process is done (eventually), I'll be splitting out the
blocking Wormhole class into a separate distribution, which doesn't
depend upon Twisted.
The latest Twisted fixes the web.Agent code we need for proper async
support. There's still a daemonization bug that prevents 'wormhole
server start' from succeeding (it hangs).
* use modern/portable "next(iter)" instead of "iter.next()"
* use six.moves.input() instead of raw_input()
* tell requests' Response.iter_lines that we want str, not bytes
We used to use twisted.python.usage.Options, hence we depended upon
Twisted. Now we depend upon "argparse" instead, which is in the py2.7
stdlib (and on pypi for 2.6). This package will still (eventually)
provide Twisted support, but applications which need it will already
express a dependency on twisted themselves, so by removing the
dependency here, we make life easier for applications that don't use it.
