Only access once to _cw.message in the login form else the first access may pop the message and the second won't get anything to display. This works on default message implementation but doesn't on the pyramid's one, leading to no message displayed on erroneous authentication attempt, which is not very user friendly.

backport 3.22 changes

backport changes from 3.21

[server,bfss] fix bfss migration test for python 3 (related #13519541)

[pkg] Use io.open with utf-8 encoding to read long description from README This forces decoding so that this is consistent between Python 2 and 3 as, in Python 3, decoding which would occur anyways and may fail depending on the environment locale settings.

[dataimport] order of ExtEntities should be irrelevant (closes #13117472)

Test and fix "pickleability" of Binary objects which has been recently broken while some cubes rely on this (eg fastimport). Do some licensing/pep8 cleanup along the way. Closes #13385274

[server,bfss] fix storage migration when Bytes attributes is None (closes #13519541) When a Bytes attributes is None before the BFSS storage migration, the migration crashes. A Bytes attribute can be None, when the attribute is not required and there is no default value. In this case, the attributes should remained None after migration and no file is stored on the disk.

Let hg Ignore py.test's .cache directory And drop rule for .svn along the way.

[entity] Add a cw_related_rqlst method returning the RQL select node of cw_related method This is useful if one wants to modify the query before execution. A bit a PEP8 style fix in tests along the way. Related to #12306543.

[devtools] set .config in setUpClass instead of using a cache in a classproperty This is much clearer and avoid problem with py.test introspection that triggered creation and caching of the configuration before actual test execution. This caused pb in unittest_postgres.PostgresStatementTimeoutTC where configuration was built before module's setup, hence source configuration was missing information about where to find the pg cluster.

[devtools] Simplify test configuration's init Specify module's __file__ instead of apphome. __file__ is saved on the class as it will be used later (eg to find the proper pg cluster without relying on shared dictionnary modifications). This will require some tests update, but it should be less common in cubes than in cubicweb itself.

[web] Have the LoginController return 403 on failed auth (closes #11569950)

[devtools] Drop old init_test_database backward compat

[devtools] show DeprecationWarning during test execution They are not shown by default since python 2.7

[devtools] deprecate usage of sources file for test This is old support which clutters the code and should no more be used. As this is rarely used (if it is) and test only, it feels ok to drop support at once without a deprecation phase.

[devtools] Set dumb value for postgres's db-host to avoid unexpected connection to a local server Currently, if something goes wrong (eg config built before call to startpgcluster) while a pg server is running on localhost, it may connect to this server and run the test in there unexepectedly.

[ldapfeed] ldap3 do not raise an exception in case of failure of cnx.bind() but return 'False' instead.

[test] add a test to ensure we get an AuthenticationError with ldapfeed when using (correct login, wrong password) credentials

[entity] Exclude computed relations from Entity.copy_relations Closes #12481591.

[pkg] Set version to 3.22.2.dev0 So that cubes used in test dependencies do not install a released CubicWeb.

[devtools] pep8 a bit package's __init__

[test/server] Only use configcls with statement timeout when needed Other tests in PostgresFTITC class apparently do not make use of this particular configuration.

[server/test] Add an assertion in test_statement_timeout

[datafeed] minor cleanups to cwxml parser

[datafeed] don't allow arbitrary kwargs on DatafeedParser initializer else they will be handled nicely by appobject base class, while we rather want an error in the case of a source parser (arguable).

[datafeed] gives information about moved entities to the parser Also, don't support anymore arbitrary parameters at parser initialization. Related to #5414754

[datafeed] simplify SQL query used to retrieve information about entities from an external source no need to join on cw_source

[datafeed] rename parser.sourceuris to source_uris Its more readable. Also, uniformize related method and local identifier names.

[datafeed] move process_urls to the parser

[tox] Use py.test to run tests In unittest_rqlrewrite.py and repotest.py, rename utility functions so that they are not considered as "test functions" by py.test.

[test] Fix devtools unittest_i18n when ran without pytest There is currently some weird error, requiring both to hack cubicweb.__path__ and to stop using load_module_from_name to load the registry. Introduce a dependency on to-be-released version of logilab common integrating fix for https://www.logilab.org/ticket/6085650 Do some extra import cleanups along the way.
