Change Log

All notable changes to this project will be documented in this file. This project adheres to Semantic Versioning.

0.19.1 (2016-01-28)

  • Consistent handling of client errors (MeteorError) which shouldn’t be logged.
  • Reduce wheel size from 204KB to 68KB by removing dddp.test package.
  • Reduce sdist size from 10MB to 209KB by removing Meteor build from test suite.
  • Improve test suite with coverage now 65% when tested via Travis CI.
  • Dropped support for Python 3.3.
  • Fix for #3 – drop support for Django 1.7, add support for Django 1.9 - thanks @schinckel.
  • Re-raise exceptions from DDP WebSocket handlers rather than swallowing them.
  • Fix for #33 – Add meteor_autoupdate_clientVersions publication.

0.19.0 (2015-12-16)

  • Dropped support for Django 1.7 (support expired on December 1 2015, see https://www.djangoproject.com/download/#supported-versions).
  • Require setuptools>=18.5 at install time due to use of python_platform_implementation environment marker.
  • Moved repository to https://github.com/django-ddp/django-ddp (new Github organisation).
  • Started work on documentation refresh.
  • Fail on start if any child threads can’t start (eg: port in use).
  • Rudimentary support for dynamic publications which may now refer to this.user.
  • Correctly close DB connections during shutdown, useful for test suite.
  • Add missing versions and dates to the change log, and note on Semantic Versioning.
  • Emit django.core.signals.request_finished to close DB connection and yield to other greenlets between processing messages from WebSocket.
  • Back to universal wheels, thanks to PEP-0496 environment markers.
  • Expand test suite coverage to start a DDP server instance and perform a HTTP GET request, no WebSocket/DDP tests yet. Fails in Pyton 3 because of a bug in gevent-websocket (https://bitbucket.org/noppo/gevent-websocket/issues/54/python-3-support).
  • Fix for #23 (Python 3 compatibility).
  • Set application_name on PostgreSQL async connection.
  • Send django.core.signals.request_finished when closing WebSocket.
  • Don’t require DJANGO_SETTINGS_MODULE to import API.
  • Tox test suite updated to runs against Python 2.7/3.3/3.4/3.5 and Django 1.8/1.9.
  • Build wheels from tox environment to ensure consistency.
  • Remove debug argment from PostgresGreenlet class (unused).

  • Don’t assume Django projects include a wsgi.py.

0.18.0 (2015-11-05)

  • Added support for METEOR_SETTINGS environment variable.

0.17.3 (2015-10-30)

  • Depend on gevent>=1.1b6 if running anything other than CPython 2.7, otherwise allow gevent 1.0 (current stable).
  • Preliminary (but broken) support for PyPy/Jython/IronPython though platform specific install_requires on psycopg2cffi instead of psycopg2 for all platforms except CPython 2/3.

0.17.2 (2015-10-29)

  • Python 3 fixes using six compatibility library (#16, #17).

0.16.0 (2015-10-13)

  • New setting: DDP_API_ENDPOINT_DECORATORS.

  • Add AleaIdMixin which provides aid = AleaIdField(unique=True) to models.

0.12.0 (2015-08-11)

  • Get path to star.json from view config (defined in your urls.py) instead of from settings.

This change includes a schema change, remember to run migrations after updating.

  • New DB field: Connection.server_addr – you must `migrate` your database after upgrading.
