3 # We put a fake "pycryptopp-0.5.24.egg" package and a fake
4 # "pycryptopp-9.9.99.tar.gz" into a directory, but the latter is
5 # booby-trapped so it will raise an exception when you try to build
8 # Then we run "python setup.py test -s
9 # buildtest.test_with_fake_dist", which imports pycryptopp
10 # and passes if pycryptopp.__version__ == '0.5.24'.
12 # (If building succeeded -- meaning that you didn't try to build the
13 # booby-trapped 9.9.99 -- but pycryptopp.__version__ != '0.5.24' then
14 # that means a different version of pycryptopp was already installed
15 # so neither of the two fake pycryptopp packages were needed. In that
16 # case this test should be treated as a "skip" -- the functionality
17 # under test can't be exercised on the current system.)
19 # The goal is to turn red if the build system tries to build the
20 # source dist when it could have used the binary dist.
22 # (Note that for this test to make sense, tahoe-lafs needs to be
23 # asking for a version of pycryptopp which can be satisfied by either
24 # 0.5.24 or 0.5.25. At the time of this writing it requires >= 0.5.20
25 # on x86 and >= 0.5.14 on other architectures.)
