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'
base62 encoding fits more information into alphanumeric chars while avoiding the troublesome non-alphanumeric chars of base64 encoding. In particular, this allows us to work around the ext3 "32,000 entries in a directory" limit while retaining the convenient property that the intermediate directory names are leading prefixes of the storage index file names.
adds a 'run' commands to bin/tahoe / tahoe.exe
it loads a client node into the tahoe process itself,
running in the base dir specified by --basedir/-C and
defaulting to the current working dir.
it runs synchronously, and the tahoe process blocks until
the reactor is stopped.
this is probably not of very high utility in the unix case of bin/tahoe
but is useful when working with native builds, e.g. py2exe's tahoe.exe,
to examine and debug the runtime environment, linking problems etc.
taking the same arguments as tahoe ls, it does a webbrowser.open to the page
specified by those args. hence "tahoe webopen" will open a browser to the
root dir specified in private/root_dir.cap by default.
this might be a good alternative to the start.html page.
* rename my_private_dir.cap to root_dir.cap
* move it into the private subdir
* change the cmdline argument "--root-uri=[private]" to "--dir-uri=[root]"
