#!./python
"""Run Python tests against multiple installations of OpenSSL and LibreSSL
The script
(1) downloads OpenSSL / LibreSSL tar bundle
(2) extracts it to ./src
(3) compiles OpenSSL / LibreSSL
(4) installs OpenSSL / LibreSSL into ../multissl/$LIB/$VERSION/
(5) forces a recompilation of Python modules using the
header and library files from ../multissl/$LIB/$VERSION/
(6) runs Python's test suite
The script must be run with Python's build directory as current working
directory.
The script uses LD_RUN_PATH, LD_LIBRARY_PATH, CPPFLAGS and LDFLAGS to bend
search paths for header files and shared libraries. It's known to work on
Linux with GCC and clang.
Please keep this script compatible with Python 2.7, and 3.4 to 3.7.
