We're just going to mark unicode in the cli as unsupported for tahoe-lafs-1.3.0. Unicode filenames on the command-line do actually work for some platforms and probably only if the platform encoding is utf-8, but I'm not sure, and in any case for it to be marked as "supported" it would have to work on all platforms, be thoroughly tested, and also we would have to understand why it worked. :-)
Also encode all args to urllib as utf-8 because urllib doesn't handle unicode objects.
I'm not sure if it is appropriate to *assume* utf-8 encoding of cli args. Perhaps the Right thing to do is to detect the platform encoding. Any ideas?
This patch is mostly due to François Deppierraz.
this adds a new service to pre-generate RSA key pairs. This allows
the expensive (i.e. slow) key generation to be placed into a process
outside the node, so that the node's reactor will not block when it
needs a key pair, but instead can retrieve them from a pool of already
generated key pairs in the key-generator service.
it adds a tahoe create-key-generator command which initialises an
empty dir with a tahoe-key-generator.tac file which can then be run
via twistd. it stashes its .pem and portnum for furl stability and
writes the furl of the key gen service to key_generator.furl, also
printing it to stdout.
by placing a key_generator.furl file into the nodes config directory
(e.g. ~/.tahoe) a node will attempt to connect to such a service, and
will use that when creating mutable files (i.e. directories) whenever
possible. if the keygen service is unavailable, it will perform the
key generation locally instead, as before.
runner provides the main point of entry for the 'tahoe' command, and
provides various subcommands by default. this provides a hook whereby
additional subcommands can be added in in other contexts, providing a
simple way to extend the (sub)commands space available through 'tahoe'
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:

This is a potentially disruptive and potentially ugly change to the code base,
because I renamed the object that serves in both roles from "Queen" to
"IntroducerAndVdrive", which is a bit of an ugly name.
However, I think that clarity is important enough in this release to make this
change. All unit tests pass. I'm now darcs recording this patch in order to
pull it to other machines for more testing.
Note that using "whatever version of python the name 'python' maps to in the current shell environment" is more error-prone that specifying which python you mean, such as by executing "/usr/bin/python setup.py" instead of executing "./setup.py". When you build tahoe (by running "make") it will make a copy of bin/allmydata-tahoe in instdir/bin/allmydata-tahoe with the shebang line rewritten to execute the specific version of python that was used when building instead of to execute "/usr/bin/env python".
However, it seems better that the default for lazy people be "whatever 'python' means currently" instead of "whatever 'python' meant to the manufacturer of your operating system".
