New releases of AutobahnPython and AutobahnTestSuite completed:


AutobahnPython
==========================

Release 0.5.0 of AutobahnPython is done, including a bunch of new
features, improvements and some fixes:

WebSocket:

 - DoS protection: WS opening handshake timeouts (configurable)
 - DoS protection: failing TCP by drop vs abort (configurable)
 - performance: optimized buffer management
 - performance: optimized/pluggable frame maskers
 - performance: PyPy compatibility/testing
 - performance: IOCP/epoll/kqueue compatibility/testing
 - feature: prepareMessage/sendPreparedMessage
 - feature: for WSS clients, automatically create TLS context
 - feature: user agent WS support detection helper

WAMP:

 - feature: exclude/eligible lists for publish

 - performance: optimized msg dispatch to subscribers

Misc:

- polished / completed docs

AutobahnTestSuite
==========================

New release of AutobahnTestSuite:

 - now comes completely packaged on PyPi
 - installs as a single tool: "wstest"
 - wstest includes 12 modes

The modes:

 - fuzzing: the known fuzzing client/server doing the WS test suite dance
 - echo: simple WS echo client and server for testing
 - broadcast: simple WS broadcast server and client driver for testing
 - testee: client and server to test Autobahn itself
 - wamp: test client and server for WAMP implementors

and

 - wsperfcontrol / wsperfmaster:

We have started collaborating with the WebSocket++ project (Peter Thorson) to build
a distributed WS load generator / performance testing tool.

This will allow running multiple instances of the "wsperf" load generator/probe
distributed both in LAN and WAN.

The probe will produce load / tests onto a testee target WS server.

AutobahnTestSuite will act as a controller for the probes, aggregate results,
produce web UI, ..

This thing is preliminary / still in the cooking .. but I think it has the potential to
take "WS testing" to the next level.

Misc Pointers
==============

 - AutobahnTestSuite (the WebSocket testsuite) : has been split off into own repo / package
 - AutobahnJS (WAMP/JS implementation) : also was split off
