[dataimport] Fix method signature Since d4bd28d5fca8, _storage_handler expect 4 args.

[dataimport] add missing import 'eschema_eid'

[test] Remove unused import in unittest_qunit.py

[dataimport] Format strings with % instead of .format() For consistency with CubicWeb code base and to avoid Python 2.6 compatibility traps.

[test] Use datapath() in massive store tests

[devtools] Disable anonymous login right before executing tests CubicWebTC.init_config is called many times, especially when creating the default database. This database is then reused by all tests in the same directory. The issue is that, if a test has 'anonymous_allowed' set to False, the anonymous user won't be created by postcreate.py in the default database. All other tests will fail miserably if they expected anonymous login to work. By actually disabling anonymous login after _init_repo, the default database (and configuration) will be initialized with a working anonymous user. Closes #7485127.

[hooks] build EnsureSymmetricRelations{Add,Delete} dynamically Instead of setting the __select__ attribute at registration time, which confuses the filterable_selectors cache when running different tests (with different schemas) in the same process, just make entirely new classes. Closes #8785708.

[qunit] stop dealing with filesystem paths qunit tests need a few things served by cubicweb: - qunit itself, which is now handled by CWDevtoolsStaticController (serving files in cubicweb/devtools/data) - standard cubicweb or cubes data files, handled by the DataController - the tests themselves and their dependencies. These can live in <apphome>/data or <apphome>/static and be served by one of the STATIC_CONTROLLERS This avoids having to guess in CWSoftwareRootStaticController where to serve things from (some files may be installed, others are in the source tree), and should hopefully make it possible to have these tests pass when using tox, and to write qunit tests for cubes, outside of cubicweb itself. This requires modifying the tests to only declare URL paths instead of filesystem paths, and moving support files below test/data/static.

[devtools] fix QUnitResultController It needs to return something.

[utils] Drop now-unused SizeConstrainedList It's last usage in CubicWeb got removed from changeset '[views] remove breadcrumbs usage to retrieve last visited page' Related to #5456850.
