[session] drop .is_repo_in_memory This is deader than a dead dog's bone buried down a blind alley off a dead-end street in a ghost town. Related to #1381328.

[session] drop session-as-a-context-manager It made little sense in the 3.19 - session-as-cnx-bw-compat era, maybe. Related to #1381328.

[devtools/repotest] use the RepoAccess object Quite better than playing tricks with the Repo._sessions. Related to #1381328.

[devtools] adapt stresstester to current APIs

[session] retire session.vreg Related to #1381328.

[session] fix super call in Connection.__init__ The vile hacks in test fixtures are fixed.

[session,repo] remove last trace of "cnxprops" Related to #1381328.

[pkg] Use Twisted < 16.0.0 We have some test failures with 16.0.0, such as: - test_put_content (unittest_server.ETwistHTTPTC) - test_base_url (unittest_httptest.TwistedCWAnonTC)

[web/views] stop using cwaction='cancel' It's broken as of https://hg.logilab.org/master/cubicweb/rev/cb217b2b3

[test] fix test_printable_value_bytes with current pygments An empty span was added in https://bitbucket.org/birkenfeld/pygments-main/commits/164574c13533195a555181a2b9c685fea2470403

[session, repository] deprecate repo.connect and move .close reponsibility to session object Repository.new_session just returns a plain session object, and `.connect` (which returns a sessionid) is deprecated. For .close:: session.close() # done ! The session will bear the responsibility to call the "session_close" event but that's better than the previous idiom:: repo.close(session.sessionid) which involves both objects. Related to #1381328. Related to #2919309.

[web/test] fix typo in doc string

[web/httpcache] send weak ETags There's no way we can provide a strong validator in general (especially considering how ETags are generated by the current EtagHTTPCacheManager and EntityHTTPCacheManager). So mark our entity-tags as weak.

[server] print backend exception if we fail to execute an sql script It's more useful to see could not open extension control file "/usr/share/postgresql/9.4/extension/postgis.control": No such file or directory rather than merely -> ERROR, skipping /usr/share/cubicweb/cubes/postgis/schema/_ext.postgres.sql

[cwctl] drop unnecessary admincnx call from 'shell' The connection is done by the migration helper.

[serverctl] allow schema-diff when db and fs are not in sync

[cwctl] remove networked remote shell This was a dbapi leftover. Related to #3933480.

[web/calendar] fix regression in previous changeset "Enables css customization in CalendarView" was untested, and introduced a crash: TypeError: not all arguments converted during string formatting

Enables css customization in CalendarView now a custom css class can be set on the calendar div (closes #3654043).

refactor a bit breadcrumbs to ease overriding of the root's display

Add migration helper function to delete entity types faster Bypasses all hooks and (for now) ignores any composite relations.

[testlib] Import nocoverage from logilab.common.testlib This depends on a change in logilab-common 1.2.0

[web/test] replace unicode with six.text_type Some uses of unicode reappeared when merging changes from 3.19.14.

[devtools/testlib] Issue a RuntimeError when a generative tests is detected Otherwise, generative tests *à la logilab-common* in CubicWebTC test cases would silently not run (at least using logilab.common.pytest runner).

[devtools] stop using lgc.testlib.TestCase It's become incompatible with unittest(2).TestCase due to generative tests. Just keep the datadir/datapath and assertCountEqual bits in our BaseTestCase.

[test] Replace remaining generative tests by subtests

[tox] Enable all applicable py34 environments All except etwist. Comes with a few tricks in tox.ini: * add ``-e.`` to force installing of cubicweb in development because dependency cubes would otherwise install cubicweb 3.22 (the latest release), which is not python3 installable. * "install" cubes/__init__.py because the file is not installed in develop mode; maybe this file should be managed by cubes themselves...

[migration/3.10] fix AttributeError 'Connection' object has no attribute 'HOOKS_DENY_ALL'
