We don't necessarily need this ourselves (__init__.py's version-checking
code is the only thing in tahoe per se that uses setuptools, and our
setup.py's use of setuptools isn't something that install_requires= can
say anything about). But at least one old environment failed because a
sub-dependency needed a newer version than Tahoe asked for. I'm not sure
if this ought to be here, but it may help for a transitional period
until these ancient environments get updated.

20.3 is the current version as of today. I'm not really sure what
version we need, but this is better than the previous zetuptoolz "0.6c6"
requirement. Closes ticket:2744.
Our setup.cfg ensures that 'setup.py update_version' happens early
enough. And doing it from tox's commands= is too late anyways (because
we aren't using Versioneer, so the _version.py file must be updated
before tox installs a static copy into the virtualenv).
The buildbot's main run-trial-with-tox command has been updated to scan
for the 'tahoe --version' output and include the version string in the
buildbot results.
The old scheme depended upon the bespoke pseudo-virtualenv scheme that
we cooked up long ago (it copied the entire source tree, bin/tahoe and
support/ and all, into the mac .pkg archive). When we moved to real
virtualenvs, that broke.
This new scheme only installs a populated virtualenv into the archive.
It replaces the entry-point bin/tahoe with a script that behaves a lot
like the old bespoke script: it inserts a relative site-packages/ into
sys.path before importing allmydata.scripts.runner and calling run().
This still depends upon the end-users $PATH having a python that is
compatible with the binary modules we've compiled here, and there are
three potentially-differing Pythons to worry about (homebrew, python.org
installers, and Apple's native /usr/bin/python). We'll have to see if
they tend to differ in ways that cause problems (I think the maintainers
generally try to avoid that). If that's an issue, the next level up is
to use bbfreeze or py2app or something in that category, to ship an
entire python, and not just a bundle of libraries.
With our new tox/pip/virtualenv -based environment, we no longer need
the bin/tahoe script, so the tests that examine it needed to change.
In particular, we no longer need to be running tests from the root of a
source tree. Instead, what we care about is that the subprocess 'tahoe'
is importing code from the same place that the unit test .py files live.
This is more cleanup from the 1582 zetuptoolzs-ectomy. __requires__ was
used to make sure that 'setup.py test' would have all our dependencies
on sys.path, but has the severe drawback of requiring all deps to be
available before any setup.py command can work, including the 'setup.py
sdist' that tox uses (to populate the new virtualenvs it creates). Now
that we use tox for tests, we don't need 'setup.py test' any more, but
I'll remove that later (after this release). Right now we just need to
get rid of this __requires__ line, as it was causing 'tox' sdist
failures.
This is needed to allow virtualenv-based builds to exercise
test_runner.BinTahoe (and a few others), which expect to run an
executable program in "bin/tahoe". This also helps users who aren't yet
accustomed to the new virtualenv world where they can just run "tahoe"
instead of "bin/tahoe".
This changes the "setup.py make_executable" command to copy the first
"tahoe" executable found on $PATH into bin/tahoe . Previously bin/tahoe
was created by modifying the shbang line of a template stored in
bin/tahoe-script.template (which has been deleted).
It also changes setup.cfg to run "make_executable" before tests,
and *after* an install. Note that you must use "setup.py install" before
"setup.py test", since make_executable requires the installed "tahoe" on
$PATH.
In the future, we hope to get rid of bin/tahoe altogether, and have
these tests run the "tahoe" from $PATH directly.
So use 'tox -e check-memory' instead of 'make check-memory'. The tox
version will create a virtualenv and install tahoe for you before
running the tests, removing one use of the 'tahoe @FILENAME' hack (which
was used to run a python file with a PYTHONPATH set to import tahoe's
dependencies).
This adds support for two environments: 'py27' for basic tests, and
'deprecations' to run tests with deprecation warnings turned on (the
latter is meant to be run from a buildbot step that knows how to count
and format the warnings nicely).
As we fix ticket:#1582, we'll move to 'tox' for running tests (which
creates its own virtualenv), so I'd like to see which buildslaves
currently have it installed, and which need to be updated.
NumDict does not make any claims about the order of its repr(), so the
test needs to be prepared for it to be stringified in any order. On unix
the old test happened to pass, but on certain windows boxes (maybe
certain versions of python?), it failed. Fixes ticket:2736.
This funky invocation syntax was introduced in 2007 (commit 56ad518),
with a comment of "make pyflakes run faster". I no longer have any idea
why that might have been the case. It's time to simplify this, because
some of our buildslaves have pipsi-installed "pyflakes" on their $PATH,
which use a "python" that's different than the one on $PATH.
I'm not sure why this ever existed, but it doesn't appear to be used.
(If an introducer called a client's set_encoding_parameters method it would
keep the provided parameters in an instance attribute but would not actually
use them.)
