The new module setup.py handles creation of package distributions in compressed formats, and performs installation of said distributions after decompression. Distribution strategy for PyDTLS is in the form of source distributions only. Building the OpenSSL library on Windows is non-trivial. Requirements include linking against the same version of the C runtime that is used by the Python interpreter, or else Microsoft redistributable installation may also need to be performed. For the convenience of Windows users, the distribution procedure includes creation of prebuilt versions of the OpenSSL library for both 32- and 64-bit versions of Windows. Despite containing binaries, these are still source distributions that are installed with "python setup.py install." A version of OpenSSL compiled with the MinGW toolchain is included. cygcrypto-1.0.0.dll and cygssl-1.0.0.dll contain symbols and can be debugged with gdb. All MinGW OpenSSL dll's link with msvcr90.dll. In order to avoid making installation a requirement after cloning, the package initializer looks for prebuilts of the currently executing platform and copies them into the dtls package directory before continuing module initialization. A distribution containing prebuilts for all platforms as well as those containing no prebuilts (appropriate for Linux) can be generated by issuing "python setup.py sdist --prebuilts." |
