[tox] Have less test environments
This is to reduce the load on CI server because of parallel clones of the
repository in Docker containers. Only keep "server", and "web" environments
separated. All other prior environments are in "misc".
To avoid duplicate entries in requirements files, move them all in a
"requirements" directory (this appears to be a "common" practice, see e.g.
Celery).
Adjustments in tests:
* Rename cubicweb/hooks/test/unittest_notification.py so that it does not
conflict with cubicweb/sobjects/test/unittest_notification.py during test
discovery as they would have the same module name but different __file__
attribute.
* Add "comment" cube to the list of expected cubes in unittest_cwconfig.py as
this cube is pulled by requirements/test-mist.txt.
Closes #15440662.
3.20 (06/01/2015)
=================
New features
------------
* virtual relations: a new ComputedRelation class can be used in
schema.py; its `rule` attribute is an RQL snippet that defines the new
relation.
* computed attributes: an attribute can now be defined with a `formula`
argument (also an RQL snippet); it will be read-only, and updated
automatically.
Both of these features are described in `CWEP-002`_, and the updated
"Data model" chapter of the CubicWeb book.
* cubicweb-ctl plugins can use the ``cubicweb.utils.admincnx`` function
to get a Connection object from an instance name.
* new 'tornado' wsgi backend
* session cookies have the HttpOnly flag, so they're no longer exposed to
javascript
* rich text fields can be formatted as markdown
* the edit controller detects concurrent editions, and raises a ValidationError
if an entity was modified between form generation and submission
* cubicweb can use a postgresql "schema" (namespace) for its tables
* "cubicweb-ctl configure" can be used to set values of the admin user
credentials in the sources configuration file
* in debug mode, setting the _cwtracehtml parameter on a request allows tracing
where each bit of output is produced

API Changes
-----------
* ``ucsvreader()`` and ``ucsvreader_pb()`` from the ``dataimport`` module have
2 new keyword arguments ``delimiter`` and ``quotechar`` to replace the
``separator`` and ``quote`` arguments respectively. This makes the API match
that of Python's ``csv.reader()``. The old arguments are still supported
though deprecated.
* the migration environment's ``remove_cube`` function is now called ``drop_cube``.
* cubicweb.old.css is now cubicweb.css. The previous "new"
cubicweb.css, along with its cubicweb.reset.css companion, have been
removed.
* the jquery-treeview plugin was updated to its latest version
Deprecated Code Drops
----------------------
* most of 3.10 and 3.11 backward compat is gone; this includes:
- CtxComponent.box_action() and CtxComponent.build_link()
- cubicweb.devtools.htmlparser.XMLDemotingValidator
- various methods and properties on Entities, replaced by cw_edited
and cw_attr_cache
- 'commit_event' method on hooks, replaced by 'postcommit_event'
- server.hook.set_operation(), replaced by
Operation.get_instance(...).add_data()
- View.div_id(), View.div_class() and View.create_url()
- `*VComponent` classes
- in forms, Field.value() and Field.help() must take the form and
the field itself as arguments
- form.render() must get `w` as a named argument, and
renderer.render() must take `w` as first argument
- in breadcrumbs, the optional `recurs` argument must be a set, not
False
- cubicweb.web.views.idownloadable.{download_box,IDownloadableLineView}
- primary views no longer have `render_entity_summary` and `summary`
methods
- WFHistoryVComponent's `cell_call` method is replaced by
`render_body`
- cubicweb.dataimport.ObjectStore.add(), replaced by create_entity
- ManageView.{folders,display_folders}
