When porting setuptools to Python 3, I recently looked into doing the
3.0 development a bit nicer, by being able to run 2to3 as a part of
the installation or test commands. However, this turns out to be
impossible, because every part of setuptools assumes that setuptools
is available and working. This also means, even under Python 2.x
development, that should you break for example the dist module a bit
too much, setuptools stops working, and you can't even run the tests.
Therefore, one thing that should be done is to make setuptools not
depend on setuptools. Building, installoing, testing, should require
disutils only.
Distutils doesn't have a "test" command... let alone an egg_info command.
It might be easier to have a "build_py" option to run 2to3 on stuff
in the build directory, and a "test" variant that runs against the
build tree instead of the source tree... and runs under Python 3
instead of 2. It's easier to see (at least for me) how something
like that could potentially work, than how to make setuptools not
depend on itself.
