  • Fixed tools.reprhandler() for compatibility with Python-3.3
  • Added *channels support to waitEvent
  • Added example of using .call
  • Fixed logic around firing the Daemonize event when registering this component during run-time and after start-up
  • Fixed use of reprhandler
  • Fixed listening channel for exceptions/errors.
  • Fixed channels for Log event.
  • Fixed config loading. Fire a Ready event when the Environment is completely ready.
  • Added .items(...) method to Config component.
  • Added BaseEvent, LiteralEvent, DerivedEvent to the core and circuits name-spaces
  • Fixed IRC protocol
  • Added has_option to Config component
  • Avoid error if user un-registers a component twice.

  • Added a new circuits.web test that ensures that large posts > 1024 bytes work
  • Updated conf so that doc can be built even if circuits isn’t installed
  • Updated reference of guide to howtos
  • Updated man headers so that they weren’t all “Components”
  • Fixed all web dispatcher tests
  • Fixed XMLRPC dispatcher. Must have a higher priority than the “default” dispatcher in order to coexist with it.
  • Fixed unit test for failure response from web component (component’s handler must have higher priority than default dispatcher if default dispatcher exists).
  • Added failure test for web controller.
  • Fixed JSON dispatcher. Must have a higher priority than the “default” dispatcher in order to coexist with it.
  • Fixed vpath traversal. vpath created in reverse (“test_args/1/2/3” became “3/2/1/test_args”).
  • Fixed evaluation of the Complete event: exclude events fired by other threads during event processing from the set of events to be tracked.
  • Don’t call tick on components that are waiting to be unregistered.
  • Using new PrepareUnregister event to reliably remove sockets from poller.
  • Fixes for PrepareUnregister and added test case.
  • Added event that informs components about going to be removed from the tree.
  • Fixed client request generation (MUST include Host header).
  • Fixed channel naming in web.Client to allow several clients (i.e. connections to web sites) to coexist in an application.
  • Prevented uncameling of event names that represent web requests. Handlers can now use the last path segment unmodified as handled event’s name.
  • Fixed the new dispatcher with new tests
  • Fixed bug in complete event generation.
  • Added optional event signaling the completion of an event and everything that has been caused by it.
  • Added the possibility to redirect the success events to other channels.
  • Updated documentation to reflect the new “handler suspend” feature.
  • Replaced web dispatcher with simpler version
  • Added support for x = yield self.callEvent(...)
  • Made test_main more reliable
  • Removed old BaseManager from playing with GreenletManager. Fixed test_manager_repr

  • Fixed test_success
  • Fixed test_removeHandler
  • Added support for firing Done() and Success() after all done executing.
  • Fixed callEvent
  • Added 2 failing tests for yield
  • Implemented promises which we detect for in circuits.web in cases where an event handler yields. Also only fire _success events after an event is well and truly finished (in the case of yielding event handlers)
  • Fixed a bug with value not being set
  • Fixed Issue #26
  • Added capability of waiting for a specific event name on a specific channel.
  • Fixed bug guarding against tasks already removed.
  • Implemented Component.init() support whereby one can define an alternative init() without needing to remember to call super(...)
  • Fixed Python 3 compatibility with Unicode strings
  • Added 99bottles as an example of concurrency. See: http://wiki.python.org/moin/Concurrency/99Bottles
  • Removed old-style channel targeting

  • Renamed _get_request_handler to just find_handler
  • Removed channels attribute from WebEvents (fix for issue #29).
  • Added Eclipse configuration files.
  • Fixed uses of deprecated syntax in app.config
  • Modified the defaults for channels. Set channels to event.channels, otherwise self.channel defaulting to *

  • Fixed a bug with the Redirect event/error in circuits.web where it didn’t handle Unicode strings
  • fixed the web dispatcher
  • Fixed test_poller_reuse test by using the now findtype() utility function
  • fixed and adds tests for the web dispatcher
  • Moved parseBody out into circuits.web.utils. Other code cleanup
  • Added a test for a bug with the dispatcher mehere found.
  • Removed itercmp() function. Added findtype() findchannel() and used better variable names. findcmp is an alias of findtype.
  • Implemented optional singleton support for components
  • Removed the circuits.web routes dispatcher as there are no tests for this and Routes dispatcher is broken - re implement at a later stage
  • Removal of End feedback event
  • Fixed web/test_value.py
  • Fixed web futures test
  • Simplified and fixed a lot of issues the circuits.bench
  • Fixed circuits.web’s exceptions tests and handling of exceptions.
  • Fixed a potential bug with circuits.web.wsgi.Application.
  • Modified Manager to only assign a handler return value if it is not None.
  • Fixed *_success and *_failure events fire on *event.channels so they go to the right place as expected. Fixed Issue #21
  • Removed event equality test and related tests. Seems rather useless and inconsistently used
  • Fixed test_gzip circuits.web test. We no longer have a Started event feedback so have to use a filter
  • Fixed a corner case where one might be trying to compare an event object with a non-event object
  • Fixed the event handling for circuits.web WebSockets Component by separating out the WebSockets handling from the HTTP handling (WebSocketsMediator).
