It isn't actually needed for Tahoe, only for the command-line tools from pyutil. Later I will make an "extras" category within pyutil to specify in a machine-readable way that argparse is not required for pyutil unless you want the command-line tools.
misc/make-version.py has a limitation which prevents it from generating version
stamps from our current darcs history. This limitation has been fixed in
pyutil's "darcsver". Rather than copy the fix from there to
misc/make-version.py, I'm making it so that you have to install pyutil if you
want to automatically generate _version.py files from the current darcs
history.
* use new decentralized directories everywhere instead of old centralized directories
* provide UI to them through the web server
* provide UI to them through the CLI
* update unit tests to simulate decentralized mutable directories in order to test other components that rely on them
* remove the notion of a "vdrive server" and a client thereof
* remove the notion of a "public vdrive", which was a directory that was centrally published/subscribed automatically by the tahoe node (you can accomplish this manually by making a directory and posting the URL to it on your web site, for example)
* add a notion of "wait_for_numpeers" when you need to publish data to peers, which is how many peers should be attached before you start. The default is 1.
* add __repr__ for filesystem nodes (note: these reprs contain a few bits of the secret key!)
* fix a few bugs where we used to equate "mutable" with "not read-only". Nowadays all directories are mutable, but some might be read-only (to you).
* fix a few bugs where code wasn't aware of the new general-purpose metadata dict the comes with each filesystem edge
* sundry fixes to unit tests to adjust to the new directories, e.g. don't assume that every share on disk belongs to a chk file.
because the setuptools "entry points" form asserts that there are
setuptools-visible packages like nevow/zope.interface (i.e. they have .egg-info
metadata). Until very recently, most debian systems did not install this
metadata. Instead, we rely upon the usual debian dependency checking as
expressed in debian/control .
