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.
Create the 'tahoe-script.py' file under the 'bin' directory. The 'tahoe-script.py' file is exactly the same as the 'tahoe-script.template' script except that the shebang line is rewritten to use our sys.executable for the interpreter. On Windows, create a tahoe.exe will execute it. On non-Windows, make a symlink to it from 'tahoe'. The tahoe.exe will be copied from the setuptools egg's cli.exe and this will work from a zip-safe and non-zip-safe setuptools egg.
When this feature is turned on, then setuptools doesn't create easy-install.pth, setuptools.pth, or site.py in the target site-packages dir. I don't know why not and we should probably open a ticket on the setuptools tracker and/or hack setuptools to create those files anyway. But for now (for the Tahoe-1.3.0 release), we're going to leave --multi-version mode off and require users to manually uninstall any packages which are too old and thus conflict with our newer dependencies.
We'll see if this fixes the tests on all of our current buildslaves, and if it does then I'll be happy to leave it at "> 1.8.1" for now, even though I don't know exactly what versions of simplejson changed exactly what behavior that interacts with exactly what environment. See http://allmydata.org/trac/tahoe/ticket/534 for uncertainties.
zooko helped me unravel a build weirdness today. somehow the system installed
twisted (/System/Library) was pulling in parts of the other twisted (/Library)
which had been installed by easy_install, and exploding.
getting rid of the latter helped, but it took this change to get the tahoe
build to stop trying to rebuild twisted and instead use the one that was
already installed. c.f. tkt #229
The 'make build' target now runs 'setup.py build_tahoe', which figures out
where the target 'supportlib' directory should go, and invokes 'setup.py
develop' with the appropriate arguments.
The 'make test' target now runs 'setup.py trial', which manages sys.path and
runs trial as a subroutine instead of spawning an external process. This
simplifies the case where Twisted was built as a dependent library (and thus
the 'trial' executable is not on PATH).
setup.py now manages sys.path and PYTHONPATH for its internal subcommands, so
the $(PP) prefix was removed from all Makefile targets that invoke setup.py .
For the remaining ones, the 'setup.py -q show_pythonpath' subcommand was
added to compute this prefix with python rather than with fragile
shell/Makefile syntax.
Remove docs/install-details.html and README.win32 for now (see #282).
Remove checks for pywin32 and pyopenssl in Makefile -- that is (or will be) automated by setuptools.
Remove twisted from setup_requires. This causes the problem in which Nevow doesn't declare its dependency on Twisted (#440) to yield a clear ImportError mentioning Twisted and to fail repeatedly, rather than yielding a weird ImportError and working on the second identical attempt.
Fix Makefile to set PATH so that trial and twistd can be found by "make test" after Twisted was installed into support/ during "make"
