Pyngus

A messaging framework built on the QPID Proton engine. It provides a callback-based API for message passing.

See the User Guide in the docs directory for more detail.

Release 2.0.3

• bugfix: fixed a memory leak
• bugfix: cyrus test fixed

Release 2.0.0

• Support for proton 0.10
• The SASL API has changed due to an API change in proton 0.10
  • Proton 0.10 implements SASL via the Cyrus SASL library
    • this change allows use of more secure authentication mechanisms, such as Kerberos
  • Applications should no longer directly access the Proton SASL class via the Connection.pn_sasl property
    • instead, the following new properties may be passed to the Container.create_connection() method:
      • x-username - (client only) the authentication id
      • x-password - (client only) the authentication password
      • x-require-auth - (server only) reject clients that do not use authentication
      • x-sasl-mechs - (server only) whitespace delimited string of acceptable mechanisms. If not supplied the mechanisms specified in the system's SASL configuration will be used. This option should only be used when the application wants to further restrict the set of acceptable mechanisms.
      • x-sasl-config-dir - (server only) the location of the directory that holds the system's Cyrus SASL configuration.
      • x-sasl-config-name - (server only) the name of the SASL configuration file (without the ".conf" suffix) in the x-sasl-dir directory.
      • NOTE WELL: Cyrus SASL cannot support multiple different SASL configurations per connection. The values of x-sasl-config-dir and x-sasl-config-name MUST be the same for all connections that use SASL.
  • the ConnectionEventHandler.sasl_step() callback has been deprecated as proton 0.10 no longer uses it
    • The ConnectionEventHandler.sasl_done() callback is still supported.
• Pyngus now enforces strict reentrancy checking. Attempting to call a non-reentrant Pyngus method will now throw a RuntimeError exception.

Release 1.3.0

• Support for proton 0.9
• Installation of proton dependencies via setup.py. This feature was added by Flavio Percoco Premoli flaper87@gmail.com - thanks Flavio!
