[repo] Use a connection instead of a session for repo.get_versions()

[webconfig] get_repository moved to repoapi

[schemaserial] Replace 'cursor' with 'cnx' We don't have cursors in rql, since execute is synchronous.

[book] basic documentation for LDAPfeed

[testlib] Use session.sessionid instead of deprecated session.id

Add data/pgdb to hgignore patterns PostgresTestDataBaseHandler uses it as datadir.

[test] make unittest_postgres pass Use PostgresApptestConfiguration which starts a postgresql cluster locally for the duration of the test.

[devtools] make PostgresTestDataBaseHandler start its own postgresql Don't depend on postgresql already running on the system, or on a static config. To use this, set the configcls attribute of your CubicWebTC-derived test class to PostgresApptestConfiguration. Caveats: - this won't work with several tests running concurrently from the same directory, since each would start its own cluster with a shared data directory and stomp on each other's toes - you need initdb/pg_ctl in $PATH, e.g /usr/lib/postgresql/$version/bin on Debian/Ubuntu systems. Closes #3489631

[web/staticcontrollers] create a unique temporary file for concat handling Predictable names means different processes can race against each other. Let's avoid that and use mkstemp to get a real unique temporary file, and atomically rename it when we're done. Closes #3524182

[server/repo] Use session.sessionid instead of session.id Silences deprecation warning.

[server/session] use _free_cnxset instead of free_cnxset to avoid warnings No need to make DeprecationWarning noise for something the user doesn't have any control over.

[server] Use internal_cnx instead of internal_session in init_repository

[server/session] session.id → session.sessionid The former causes deprecation warnings.

English typography Get rid of extra space before `!' and `?'

[repo] restore python 2.6 compatibility Broken in 12dfce15c8ea.

[server] use internal_cnx instead of internal_session in deserialize_schema

[server/schemaserial] rename cursor argument to cnx cursor is a sql concept it has no meaning for rql.

[repo] Use a connection instead of a session in Repository.properties()

[server/sources] replace references to dbapi with repoapi

[doc/3.19] Make repoapi description match code

[serverctl] remove broken schema-sync command As far as I can tell the migration handler hasn't had a cmd_synchronize_schema method since cubicweb 3.2.0.

[server/session] Fix docstring typo for InternalSession

[book] typo

[server] fix TypeErrors With multisource gone, cnxset.reconnect() doesn't take a source argument. Broken since d62e13eba033.

[notification] use an InternalManager object for notifications if we have an (email, lang) tuple The non-uniform handling of CWUser vs (email, lang) tuple has caused too many bugs; this change mostly unifies the two code paths. Closes #3381521

[req] if a user has a None property, fall back to the default This can happen for InternalManager; the normal CWUser implementation of property_value already has a similar fallback. Related to #3381521

[server] Allow setting an InternalManager's preferred language Related to #3381521
