# The 'darcsver' setup.py command comes in the 'darcsver' package:
# http://pypi.python.org/pypi/darcsver It is necessary only if you want to
# automatically produce a new _version.py file from the current darcs history.
make-version:
	$(PYTHON) ./setup.py darcsver --count-all-patches

# We want src/allmydata/_version.py to be up-to-date, but it's a fairly
# expensive operation (about 6 seconds on a just-before-0.7.0 tree, probably
# because of the 332 patches since the last tag), and we've removed the need
# for an explicit 'build' step by removing the C code from src/allmydata and
# by running everything in place. It would be neat to do:
#
#src/allmydata/_version.py: _darcs/patches
#	$(MAKE) make-version
#
# since that would update the embedded version string each time new darcs
# patches were pulled, but without an obligatory 'build' step this rule
# wouldn't be run frequently enough anyways.
#
# So instead, I'll just make sure that we update the version at least once
# when we first start using the tree, and again whenever an explicit
# 'make-version' is run, since then at least the developer has some means to
# update things. It would be nice if 'make clean' deleted any
# automatically-generated _version.py too, so that 'make clean; make all'
# could be useable as a "what the heck is going on, get me back to a clean
# state', but we need 'make clean' to work on non-darcs trees without
# destroying useful information.

# c.f. ticket #455, there is a problem in the intersection of setuptools,
# twisted's setup.py, and nevow's setup.py . A Tahoe build, to satisfy its
# dependencies, may try to build both Twisted and Nevow. If both of these
# occur during the same invocation of 'setup.py develop', then the Nevow
# build will fail with an "ImportError: No module named components". Running
# the build a second time will succeed. Until there is a new version of
# setuptools which properly sandboxes sys.modules (or a new version of nevow
# which doesn't import twisted during its build, or a new version of twisted
# which doesn't import itself during its build), we just build tahoe twice
# and ignore the errors from the first pass. Updated 16-Sep-2008: now we need
# three invocations.
