versioning: include an "appname" in the application version string in the versioning protocol, and make that appname be controlled by setup.py
It is currently hardcoded in setup.py to be 'allmydata-tahoe'. Ticket #556 is to make it configurable by a runtime command-line argument to setup.py: "--appname=foo", but I suddenly wondered if we really wanted that and at the same time realized that we don't need that for tahoe-1.3.0 release, so this patch just hardcodes it in setup.py.
setup.py inspects a file named 'src/allmydata/_appname.py' and assert that it contains the string "__appname__ = 'allmydata-tahoe'", and creates it if it isn't already present. src/allmydata/__init__.py import _appname and reads __appname__ from it. The rest of the Python code imports allmydata and inspects "allmydata.__appname__", although actually every use it uses "allmydata.__full_version__" instead, where "allmydata.__full_version__" is created in src/allmydata/__init__.py to be:
All the code that emits an "application version string" when describing what version of a protocol it supports (introducer server, storage server, upload helper), or when describing itself in general (introducer client), usese allmydata.__full_version__.
This fixes ticket #556 at least well enough for tahoe-1.3.0 release.
setup: removed bundled darcsver-1.2.0
(I'm about to add a new bundled darcsver-1.2.1, but I want to see what the buildbots will do when there is no bundled darcsver present.)

tests: increase the default timeout for SystemTestMixin -based tests to 300 seconds, since our slower buildslaves sometimes take longer than the default 120s
immutable: tests: the real WRITE_LEEWAY is 35 (it was a mistake to move it from 10 to 35 earlier -- I had seen a failure in which it took 35 times as many writes as I thought were optimal, but I misread and thought it took only 20 times as many)
immutable: defensive programming: assert that the encrypted readable gave you no more than the number of bytes you asked for
(There is a bug in the current DownUpConnector which can cause it to give more bytes than you asked for on one request, and then less on the next, effectively shifting some of the bytes to an earlier request, but I think this bug never gets triggered in practice.)
immutable: tests: sigh, raise, again the limit of how many extra writes you can do and still pass this test
Obviously requiring the code under test to perform within some limit isn't very meaningful if we raise the limit whenever the test goes outside of it.
But I still don't want to remove the test code which measures how many writes (and, elsewhere, how many reads) a client does in order to fulfill these duties.
Let this number -- now 20 -- stand as an approximation of the inefficiency of our code divided by my mental model of how many operations are actually optimal for these duties.
immutable: tests: assert that verifier gives a clean bill of health after corruption and repair (the previous patch mistakenly did this only after deletion and repair), and also test whether deleting seven other shares and then downloading works. Also count the number of shares stored in the local filesystem.
immutable: test: add a test after attempting to repair from corruption: does a full verify run give the file a clean bill of health? If not, the you haven't successfully repaired it.
This will make the repairer tests more consistent -- less accidentally passing due to getting lucky.
immutable: tests: put shares back to their pristine condition in between each test of corrupting-and-repairing them
This is important, because if the repairer doesn't completely repair all kinds of corruption (as the current one doesn't), then the successive tests get messed up by assuming that the shares were uncorrupted when the test first set about to corrupt them.

setup: bundle setuptools-0.6c12dev (our own toothpick of setuptools) this version completes my patch to fix http://bugs.python.org/setuptools/issue54 , which is necessary for tahoe to build with --prefix=support without doing a lot of PYTHONPATH gymnastics around the call to setup.py
roll back the upgrade of the bundled setuptools_trial from 0.5 to 0.5.1
Upgrading setuptools trial in that way leads to a very tricky problem in setuptools's handling of recursive installation of the build-time dependencies of build-time dependencies...
rolling back:

* setup: bundle new setuptools_trial-0.5.1
A ./misc/dependencies/setuptools_trial-0.5.1.tar
Tue Feb 3 22:17:32 MST 2009 zooko@zooko.com
* setup: remove old bundled setuptools_trial
setup: remove a couple of horrible work-arounds in setup.py now that we rely on our own toothpick of setuptools which fixes those issues
also specify that we need our latest revision (11dev) of our toothpick of setuptools
also *always* setup_require setuptools_darcs at module import time. Formerly we added setup_require setuptools_darcs only if the PKG-INFO file were not already created. There is some weird, irreproducible bug to do with setuptool_darcs, and I guess that the fact that whether it is required or not depends on that autogenerated file might have something to do with it. Anyway, this is simpler.
setup: bundle setuptools-0.6c11dev (our own toothpick of setuptools)
Hopefully this one fixes the issue with easy_install not searching the sys.path for packages that were requested to be installed, (setuptools #17), thus allowing us to do away with the "--site-dirs=" kludges, which are currently breaking some of our buildbots.

Makefile: use 'setup.py test' for test/quicktest targets (instead of
'setup.py trial'). 'setup.py trial' clobbers the tahoe .egg's PKG-INFO
"Version:" field (resetting it to 0.0.0), possibly because it isn't invoking
the darcsver subcommand that 'setup.py test' does before it runs the 'trial'
subcommand.
This slows down quicktest by another couple of seconds (see #591) and adds
more noise to its output, but without this change, 'make test' and 'make
quicktest' fail on test_runner (which spawns bin/tahoe as a subprocess, and
with a mangled Version:, the setuptools-based entry point script refuses to
recognize our source tree as a usable version of Tahoe).
