2017-04-27 Ray Brown Release 1.2.3 * dtls/wrapper.py: Add optional parameter to DtlsSocket: client_timeout (seconds). If client_timeout is specified, clients that have not communicated within the time frame will be dropped. * setup.py: Version incremented to 1.2.3 * dtls/__init__.py: Increment version 2017-04-10 Ray Brown Release 1.2.2 Produce a Pure Python Wheel instead of a source distribution for Linux. This speeds up installation and simplifies distribution building. * setup.py: Drop support for sdist; add support for bdist_wheel without --plat-name switch; persist README.rst; increment version * dtls/__init__.py: Increment version 2017-04-06 Ray Brown Installation Fixes and Improvements Installation as well as distribution generation are now simplified. With the elimination of MinGW support there is now a unique set of platform binaries for 32-bit and 64-bit Windows. Pip will now automatically choose the proper binary wheel or the source distribution, depending under which platform and Python version it is being invoked. * README.md: add installation section * setup.py: rewrite to use bdist_wheel for Windows 2017-04-03 Ray Brown Release 1.2.0 * README.md: Release updates 2017-04-02 Ray Brown Release 1.2.0 Preparation * README.txt -> README.md: renamed * dtls/sslconnection.py: Reduce the default MTU in effect while handshaking to 576, suitable for various path MTUs and PPPoE * dtls/prebuilt/win32-x86[_64]: Rebuilt with Visual C++ 2008 to eliminate requirement to install a C++ redistributable package * dtls/prebuilt/mingw-x86: mingw support is deprecated * dtls/__init__.py: VERSION introduced * setup.py: Version incremented to 1.2.0 2017-03-28 Björn Freise Workaround for Windows concerning the MTU size * dtls/sslconnection.py: Hardcoded setting of the MTU size only for Windows and in case it is not already configured * dtls/test/unit_wrapper.py: No user config of the MTU size; using the hardcoded one from SSLConnection 2017-03-28 Björn Freise Minor fixes and "hopefully" compatible to Ubuntu 16.04 * dtls/__init__.py: Removed wrapper import * dtls/openssl.py: Fixed line endings to LF * dtls/patch.py: Removed PROTOCOL_SSLv3 import and fixed line endings to LF * dtls/sslconnection.py: Fixed line endings to LF * dtls/test/certs/*_ec.pem: Fixed line endings to LF * dtls/test/echo_seq.py: Fixed line endings to LF * dtls/test/simple_client.py: Fixed line endings to LF * dtls/test/unit.py: Fixed line endings to LF * dtls/test/unit_wrapper.py: Corrected wrapper import and fixed line endings to LF * dtls/util.py: Fixed line endings to LF * dtls/wrapper.py: Corrected function naming to wrap_client() and wrap_server(); Fixed line endings to LF * dtls/x509.py: Fixed line endings to LF 2017-03-23 Björn Freise Patched ssl-Module with SSL_BUILD_*- and ERR_*- constants and added aliases for wrap_server() and wrap_client() * dtls/__init__.py: Added DtlsSocket() from wrapper and aliases for wrap_server() and wrap_client() * dtls/err.py: Added patch_ssl_errors() to patch ssl-Module with ERR_* constants * dtls/patch.py: Patched ssl-Module with SSL_BUILD_* constants and added call to patch_ssl_errors() * dtls/wrapper.py: -
