0.30.3 - 2013-11-20

  • removal of some debug code that was left in heka-py
  • modified the StdlibPayloadEncoder for stdlib logging so that the message type is prefixed to the payload. This lets you differentiate counters, timers and other kinds of messages.

0.30.2 - 2013-09-23

  • ProtocolBuffer support matches hekad 0.4.0
  • API cleanups!
  • Dropped the entire heka.senders namespace
  • Removed the zeromq dependency as we don't support zeromq in hekad yet.
  • Dropped the NoSendSender
  • JSON message encoding is no longer supported. There is now only one message encoder supported ProtobufEncoder

0.30.1 - 2013-08-16

  • throw errors if None is passed into the 'fields' dictionary of the of client.heka()

0.30 - 2013-06-25

  • minor updates to the ProtocolBuffer protocol to match hekad 0.3

0.20 - 2013-04-26

  • a completely reworked wire level protocol has been implemented to match hekad 0.2
  • timestamps formats have been changed to nanoseconds from UTC epoch.
  • uuid per message
  • protocol buffers!
  • tcp support!
  • message signing support
  • refactored the senders into streams and encoders so that you can pick from (UDP|TCP) with (JSON|ProtocolBuffer)

_ 0.10 - 2013-03-12 ================== - rename package from metlog-py to heka-py - refactor conditional imports to single util module

0.9.10 - 2012-12-28

  • changed the _config attribute to be a flat json string for simpler debugging in production systems

0.9.9 - 2012-12-18

  • Added a _config attribute on the client instance so you can inspect the actual configuration that is in play.

0.9.8 - 2012-10-05

  • HekaClient now accepts single string values for the disabled_timers argument.
  • Fixed bug where timer wouldn't be disabled if the function name didn't match the timer name.
  • Added better error handling for invalid unicode. Unserializable messages will now get routed to stderr
  • A new heka benchmark command line utility (mb) is now included

0.9.7 - 2012-09-11

  • Fixed a bug where client_from_dict_config would mutate the input configuration causing subsequent use of the configuration to fail.

0.9.6 - 2012-09-11

  • Couple of bug fixed in decorator base class.
  • Added support for UdpSender to have multiple listener hosts.

0.9.5 - 2012-08-14

  • Properly handle 'self' arguments when decorators are used on a method.
  • Only apply string formatting to 'oldstyle' messages if string formatting args are actually provided.

0.9.4 - 2012-07-25

  • Added a testcase against the UDP input plugin.
  • Fixed bug in socket.sendto function signature.

0.9.3 - 2012-07-18

  • HekaClient's override argument now accepts method name to override instead of True.
  • Decorator tests now get the expected envelope version from the module source code rather than hard coded in the tests.
  • Added udp sender.

0.9.2 - 2012-06-22

  • Plugin method names are now expected to be stored in the heka_name attribute of the provided function rather than passed in separately.
  • 'oldstyle' messages now support string substitution using provided args and the exc_info keyword argument for slightly better stdlib logging compatibility.
  • ZeroMQ sender now uses gevent safe implementations of Queue class and zmq module if the gevent monkeypatches have been applied.

0.9.1 - 2012-06-08

  • Added StdLibLoggingSender that delegates message delivery to Python's standard library logging module.

0.9 - 2012-05-31

  • Refactored / simplified filter and plug-in config loading code
  • Filter functions now use closures for filter config (matching plug-in config) instead of passing the config as an argument each time.
  • HekaClient.add_method now supports override argument to force the issue of replacing existing attributes.
  • Added heka_hostname and heka_pid to the message envelope handed to the sender.
  • Added support for rate argument to HekaClient.incr method.
  • HekaClient.timer converted from a property to a method, allowing for much better performance and much simpler code.
  • Got rid of new_default argument HekaClientHolder.delete_client. Folks can set a new default w/ another function call if necessary.
  • DebugCaptureSender.__init__ now accepts arbitrary keyword args and stores them as attributes on the instance to allow for easier testing of the config parsing code.

0.8.5 - 2012-05-07

  • Replaced heka.decorators.base.HekaClientWrapper with heka.holder.HekaClientHolder which is a bit more useful and a bit more sane.
  • Moved Python stdlib logging compatibility hooks into its own module.
  • Updated config parsing to support global values stored in the CLIENT_HOLDER.
  • Added is_active property to HekaClient.
  • Heavily revised "Getting Started" documentation.
  • Added dict_from_stream_config function to config.
  • Extracted StreamSender from StdOutServer, added support for arbitrary formatters for the output.
  • Added ZmqHandshakePubSender which communicates w/ clients via a control channel.
  • ZMQ senders now use connection pooling.

0.8.4 - 2012-04-18

  • "Getting started" documentation
  • Overall documentation ToC
  • Added Heka stdlib logging handler so logging in dependency libraries can be routed to Heka
  • Use 0mq connection pool instead of creating a new 0mq connection for each new thread
  • Initial implementation of 0mq "Handshaking Client" which will use a separate control channel to establish communication with 0mq subscribers.
  • Added debug_stderr flag to ZmqPubSender which will also send all output to stderr for capturing output when error messages aren't getting through to the Heka listener.

0.8.3 - 2012-04-05

  • Added support for simple message filtering directly in the heka client
  • "Heka Configuration" documentation
  • Added support for setting up client extension methods from configuration

0.8.2 - 2012-03-22

  • Added config, decorators, and exceptions to sphinx API docs
  • Support for passing a client in to the client_from_* functions to reconfigure an existing client instead of creating a new one
  • Docstring / documentation improvements
  • Added reset method to HekaClientWrapper
  • Add support for keeping track of applied decorators to HekaDecorator class
  • Added NoSendSender class for use when a client is create w/o a sender

  • Support for dynamic extension methods to be added to HekaClient
  • "Classic" logger style API added to HekaClient
  • Helper code added to create client and sender from configuration data

  • README file is now used as package long_description value

0.8 - 2012-02-13
