# We put a fake "pycryptopp-0.5.24.egg" package and a fake
|
|
# "pycryptopp-9.9.99.tar.gz" into a directory, but the latter is
|
|
# booby-trapped so it will raise an exception when you try to build
|
|
# it.
|
|
|
|
# Then we run "python setup.py test -s
|
|
# buildtest.test_with_fake_dist", which imports pycryptopp
|
|
# and passes if pycryptopp.__version__ == '0.5.24'.
|
|
|
|
# (If building succeeded -- meaning that you didn't try to build the
|
|
# booby-trapped 9.9.99 -- but pycryptopp.__version__ != '0.5.24' then
|
|
# that means a different version of pycryptopp was already installed
|
|
# so neither of the two fake pycryptopp packages were needed. In that
|
|
# case this test should be treated as a "skip" -- the functionality
|
|
# under test can't be exercised on the current system.)
|
|
|
|
# The goal is to turn red if the build system tries to build the
|
|
# source dist when it could have used the binary dist.
|
|
|
|
# (Note that for this test to make sense, tahoe-lafs needs to be
|
|
# asking for a version of pycryptopp which can be satisfied by either
|
|
# 0.5.24 or 0.5.25. At the time of this writing it requires >= 0.5.20
|
|
# on x86 and >= 0.5.14 on other architectures.)
