"""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.
