Changelog
---------
High-level changelog. For details, consult the SVN logs.
:4.0.3 (Jan 2019):
* Cleanup for Python 3.7 (mostly add support for keyword-only args, use
Python 3 inspect signature/Parameter and add tests for
:4.0.0 (Dec 2016):
* Verified support Python 3.5 and 3.6
* Distribution via wheel
* Abandon support for Python 2.x and easy_install; now requires Python >= 3.3
* Abandon support for long-ago deprecated arg1 messaging protocol
* Added currying of subscribed listener args
* Significant speed improvement for message delivery
* Use PEP 484 style of annotations throughout
* Use enum instead of constants when practical
:3.3.0 (Feb 2014):
* cleanup low-level API: exception classes, moved some out of pub module that did not
belong there (clutter), move couple modules; specifically:
* Removed from pub (available on object returned from pub.getDefaultTopicMgr())
* getOrCreateTopic -> pub.getDefaultTopicMgr().getOrCreateTopic
* getTopic -> pub.getDefaultTopicMgr().getTopic
* newTopic -> pub.getDefaultTopicMgr().newTopic
* delTopic -> pub.getDefaultTopicMgr().delTopic
* getAssociatedTopics -> pub.getDefaultTopicMgr().getTopics
* getDefaultTopicTreeRoot -> pub.getDefaultTopicMgr().getRootAllTopics
* Removed from pub (available from pubsub.core):
* ITopicDefnProvider
* Moved from pub into to pubsub.core.TopicDefnProvider class as classmethod:
* registerTopicDefnProviderType
* Renamed:
* TopicNameInvalid -> TopicNameError
* UndefinedTopic(RuntimeError) -> TopicNameError(ValueError)
* UndefinedSubtopic(RuntimeError) -> TopicNameError(ValueError)
* ListenerInadequate(TypeError) -> ListenerMismatchError(ValueError)
* UnrecognizedImportFormat -> UnrecognizedSourceFormatError
* ListenerSpecInvalid -> MessageDataSpecError
* SenderMissingReqdArgs -> SenderMissingReqdMsgDataError
* SenderUnknownOptArgs -> SenderUnknownMsgDataError
* ListenerNotValidatable -> TopicDefnErrorcd
* Changed;
* Topic.isSendable -> hasMDS
* TopicManager.??? -> isTopicInUse + hasTopicDefinition
* completed the ref docs
* support installation via pip
* cleanup versioning metadata: use pubsub.__version__ instead of pub.PUBSUB_VERSION
* support Python 3
* add getListenersIter() to iterate over listeners without temp copy of listener list
* add deprecation message when import setuparg1
* new wxPubsubMonitor utility class
:3.2.0 (sep 2013):
- cleanup of docs
- merged importTopicTree to addTopicDefnProvider
- renamed pub.getDefaultRootAllTopics to pub.getDefaultTopicTreeRoot
- removed pub.importTopicTree, use pub.addTopicDefnProvider(source, format)
- renamed pub.exportTopicTree to pub.exportTopicTreeSpec
- several minor bug fixes
- incorporated some patches contributed by users: one for performance improvement when
high-frequency of subscribers/messages; one for reading topic tree specification from
XML rather than .py module
- v1 and v2 APIs no longer supported
:3.1.2 (2011):
- added some docs
- more configurable importTopicTree
- using importTopicTree now allows to use the topic hierarchy as topic names instead of
string, thereby enabling python editors to support PyPubSub-based development via
code completion and sendMessage keyword arguments.
:3.1.1b (2010):
- cleanup docs
- couple minor tweaks (for instance added pub.getMsgProtocol())
:3.1.0b (2009):
- Import/export of topic tree and its documentation using Python interpreter
- Better support for evolving topic tree during application development,
with "freezing" certain parts of tree
- Helper functions to transition from *arg1* to *kwargs* messaging protocol
- Improved error messages (in exceptions raised)
- PyPubSub can be installed inside other packages and will not interfere with
system-wide pubsub
- pubsubconf module moved inside pubsub package so manual install easier
- Support !**kwargs in listeners
- Support for more than one pubusb notification handler
- Multiple publisher engines in one application (for instance, in separate
threads, or for different "domains" in a large application)
- Upgraded docs
- Bug fixes, cleanup
:3.0 (2008):
- Use keyword arguments in sendMessage
- Support any kind of listener, not just those with one unnamed argument
- Validate listeners at subscription time
- Support "inheritance" of keyword arguments by subtopics during
message sending (prevents a common bug which was to send data using
wrong argument names).
- Topic tree can be documented (including topic message arguments)
- Support user-defined notification handling of certain events occuring in
PyPubSub such as "subscribe", "sendMessage".
- Support user-defined exception handling of exceptions raised by
listeners
- Proto-Documentation on own website using Sphinx
- Separate regression testing folder for nose-based automated testing
- Configuration module for choosing which PyPubSub API to use in application,
useful for backwards compatibility
:2.0 (2007):
- more Pythonic API (new ``PublisherClass`` API, at module level
so easier to call -- no need to know about singleton)
- Support definition of topic tree via a python class, for increased
rigor and documentability of topics
- Topics are objects
:1.0 (2005):
- Given its own "home" as separate package from wxPython's ``wx.lib.pubsub``
- Factored out weakmethod
- Put on Cheese Shop
:Pre 1.0:
- Created by Rob Shecter in wxPython's ``wx.lib`` (early 2000?)
- Weakmethod added by Oliver Schoenborn (2004)
- Further development transfered to Schoenborn (2004)
