setup: make find_trial self-contained so that we don't have a bootstrapping problem -- if allmydata can't be imported we still want to be able to run find_trial
setup: require specific versions of dependencies, both at run-time (if pkg_resources is available) and at build-time, and make there be only once place where we specify those versions
Using pkg_resources.require() like this also apparently allows people to install multiple different versions of packages on their system and tahoe (if pkg_resources is available to it) will import the version of the package that it requires. I haven't tested this feature.
setup: for reasons that I do not understand "show-eggspath" gives me a GNUmake error unless I move it down a couple of stanzas (until after the stanza that sets PYTHONPATH)
setup: add a setup.cfg file which instructs setuptools to install all eggs in unzipped form and to always copy them into the target directory (even if they are already installed somewhere else on the path that setuptools searches, which includes the CWD)

offloaded: reinstate fix for windows tests
in a discussion the other day, brian had asked me to try removing this fix, since
it leads to double-closing the reader. since on my windows box, the test failures
I'd experienced were related to the ConnectionLost exception problem, and this
close didn't see to make a difference to test results, I agreed.
turns out that the buildbot's environment does fail without this fix, even with
the exception fix, as I'd kind of expected.
it makes sense, because the reader (specifically the file handle) must be closed
before it can be unlinked. at any rate, I'm reinstating this, in order to fix the
windows build

update confwiz to include account creation ui
this changes the confwiz so that hitting the 'create account' button, rather than
opening a webbrowser to the register page, instead provides a simple account creation
ui directly, along with changes to the backend (native_client.php) to support that.
also added a 'connecting...' message so the user sees a response when they hit
login or create account, since the getBasedir call can sometimes take up to ~5min
(which is unacceptable for a user product, but this at least somewhat ameliorates
the issue of the ui locking up and not giving the user any feedback while it's
happening)
setup: it is okay to leave src/allmydata_tahoe.egg-info in place
This directory allows programs to programmatically identify tahoe and its version number while "running from source" -- i.e. using ./setup.py develop.
setup: simplify the setup by removing the "tahoe dependencies" fake project
Now we use "./setup.py develop" to ensure that changes to our source code are immediately used without requiring a "make" step. This simplification will hopefully pave the way for easier py2exe and py2app, solving the "Unit tests test the installed version" bug (#145), and perhaps also #164 and #176.
This patch also conditionalizes the use of setuptools_darcs on the absence of a PKG-INFO file, which is part of fixing #263.
doc: architecture.txt: start updating architecture.txt
I chose to remove mention of non-convergent encoding, not because I dislike non-convergent encoding, but because that option isn't currently expressed in the API and in order to shorten architecture.txt. I renamed "URI" to "Capability". I did some editing, including updating a few places that treated all capabilities as CHK-capabilities and that mentioned that distributed SSKs were not yet implemented.
doc: add an overview to about.html
Hopefully this overview has the right combination of generality and precision to satisfy The Norm Hardy Request:

offloaded: fix failure in unit test on windows
in trying to test my fix for the failure of the offloaded unit test on windows
(by closing the reader before unlinking the encoding file - which, perhaps
disturbingly doesn't actually make a difference in my windows environment)
I was unable too because the unit test failed every time with a connection lost
error.
after much more time than I'd like to admit it took, I eventually managed to
track that down to a part of the unit test which is supposed to be be dropping
a connection. it looks like the exceptions that get thrown on unix, or at
least all the specific environments brian tested in, for that dropped
connection are different from what is thrown on my box (which is running py2.4
and twisted 2.4.0, for reference) adding ConnectionLost to the list of
expected exceptions makes the test pass.
though curiously still my test logs a NotEnoughWritersError error, and I'm not
currently able to fathom why that exception isn't leading to any overall
failure of the unit test itself.
for general interest, a large part of the time spent trying to track this down
was lost to the state of logging. I added a whole bunch of logging to try
and track down where the tests were failing, but then spent a bunch of time
searching in vain for that log output. as far as I can tell at this point
the unit tests are themselves logging to foolscap's log module, but that isn't
being directed anywhere, so all the test's logging is being black holed.

tweak py2exe setup.py to link in xmlplus iff present
so in the build slave's environment, everything builds and runs fine without
'_xmlplus'. In my existing local environment everything builds and runs only
if I tell py2exe to explicitly link in '_xmlplus'.
the _xmlplus module, tested for by the python standard library, comes from
PyXML ( http://pyxml.sf.net ) a project which is no longer maintained and,
for instance, hasn't released a build for windows past python 2.4
hence something about the way nevow and the std lib import xml dependencies
causes build environment incompatabilities between my box (which is running
py24 currently) and the buildslave (which is on py25, and doesn't have PyXML)
(if I remove _xmlplus from my environment, then a different set of nevow/xml
import problems emerge, which do not occur in the buildslave's py25 env)
this change tests the environment the build is happening in, and if the
_xmlplus package is importable, then py2exe is directed to link it into the
build. otherwise the package is left out. as far as I comprehend the issue
this should make both of these environments work. if other people have
problems around this issue, obviously I'm interested in learning more.

windows installer build refinements
this resolves problems of py2exe's modulefinder collection of sources from
.zipped egg files, not by using easy_install to reach the --always-unzip
option, but rather with a small tool which unpacks any zipped egg files found
in misc/dependencies. this fixes the py2exe build given rollback of the
easy_install stuff which had broken the unix builds. misc/hatch-eggs.py
performs the honours.
this also includes a misc/sub-ver.py tool which substitutes elements of the
verion number for the current code base (by importing allmydata.__version__
hence make-version should be run first, and the python path carefully managed)
into template files using python's string interpolation of named args from a
dict as the templating syntax. i.e. %(major)d %(minor)d %(point)d %(nano)d
each expand to the individual components of the version number as codified
by the pyutil.version_class.Version class. there is also a %(build)s tag
which expands to the string form of the whole version number. This tool is
used to interpolate the automatically generated version information into the
innosetup source file in a form consistent with innosetup/windows' restrictions

fix nevow build prob for py2exe
nevow attempts to use pkg_resources to find the formless css file upon
import, if pkg_resources is available. unfortunately using pkg_resources
to find files is not supported if the files are being loaded from a zip
archive (i.e. only source and egg), and further py2exe uses a zip bundle
for all the code and dependent libraries. hence having both pkg_resources
and nevow built into an exe causes nevow to explode upon import.
this tells py2exe not to link pkg_resources into the target, so that
this behaviour isn't stimulated. the side effect being that pkg_resources
isn't available.

the existence of the file, and if it is not found, attempts to find it relative
to sys.executable instead.
