* 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
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
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.

Increase version to 1.0.1, in preparation for PyPI release. This release
includes a fix by Jayson Vantuyl to an error code import. A proper error
is now emitted when omitting the keyfile on a PyDTLS server.
The version number is incremented to 1.0.0.
Thanks to doneir for reporting that a number of unit test were failing.
This was because two test certificates had expired. This commit replaces
these with updated certificates, along with the tool used for programmatic
certificate generation. The new certificates are set to remain valid for
approximately ten years.
This patch allows the module test_perf.py to be run on Windows. It
contains fixes primarily accounting for differences in the
implementation of the multiprocessing module among platforms.
This patch completes the README.txt placeholder file. The first version of
external (as opposed to in-line) documentation is complete.
The unused file README.md that was created by the GitHub repository
establishment procedure is deleted.
This project is now licensed under the Apache license. Individual files
now have a license reference header.
The Apache 2.0 license text is copied to the file LICENSE. The file
NOTICE, referred to in the license text, has been added. A placeholder
README.txt has been added.
These three new files are integrated into the distribution/installation
machinery, and are placed into the package directory upon installation.
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."
When running in remote server mode (-s), the value of the -s option
specifies which port remote clients must connect to for the job
transmission protocol. The servers for individual suite runs, however,
would be placed at dynamically assigned ports, with port numbers
transmitted to clients through job parameters.
This does not work well when servers sit behind firewalls with restricted
UDP port ranges. This patch introduces the -p option, allowing ports for
server runs to remain fixed at the given port (which, of course, must
not conflict with the port number supplied with -s).
