[json] Stop serializing cw_source into default json representation of an entity
Related to #15538288
3.21 (10 July 2015)
===================
New features
------------
* the datadir-url configuration option lets one choose where static data files
are served (instead of the default ${base-url}/data/)
* some integrity checking that was previously implemented in Python was
moved to the SQL backend. This includes some constraints, and
referential integrity. Some consequences are that:
- disabling integrity hooks no longer disables those checks
- upgrades that modify constraints will fail when running on sqlite
(but upgrades aren't supported on sqlite anyway)
Note: as of 3.21.0, the upgrade script only works on PostgreSQL. The
migration for SQLServer will be added in a future bugfix release.
* for easier instance monitoring, cubicweb can regularly dump some statistics
(basically those exposed by the 'info' and 'gc' views) in json format to a file
User-visible changes
--------------------
* the use of fckeditor for text form fields is disabled by default
* the 'https-deny-anonymous' configuration setting no longer exists
Code movement
-------------
The cubicweb.web.views.timeline module (providing the timeline-json, timeline
and static-timeline views) has moved to a standalone cube_
.. _cube: https://www.cubicweb.org/project/cubicweb-timeline
API changes
-----------
* req.set_cookie's "expires" argument, if not None, is expected to be a
date or a datetime in UTC. It was previously interpreted as localtime
with the UTC offset the server started in, which was inconsistent (we
are not aware of any users of that API).
* the way to run tests on a postgresql backend has changed slightly, use
cubicweb.devtools.{start,stop}pgcluster in setUpModule and tearDownModule
* the Connection and ClientConnection objects introduced in CubicWeb 3.19 have
been unified. To connect to a repository, use::
session = repo.new_session(login, password=...)
with session.new_cnx() as cnx:
cnx.execute(...)
In tests, the 'repo_cnx' and 'client_cnx' methods of RepoAccess are now
aliases to 'cnx'.
Deprecated code drops
---------------------
* the user_callback api has been removed; people should use plain
ajax functions instead
* the `Pyro` and `Zmq-pickle` remote repository access methods have
been entirely removed (emerging alternatives such as rqlcontroller
and cwclientlib should be used instead). Note that as a side effect,
"repository-only" instances (i.e. without a http component) are no
longer possible. If you have any such instances, you will need to
rename the configuration file from repository.conf to all-in-one.conf
and run ``cubicweb-ctl upgrade`` to update it. Likewise, remote cubicweb-ctl
shell is no longer available.
* the old (deprecated since 3.19) `DBAPI` api is completely removed
* cubicweb.toolsutils.config_connect() has been removed
