[server/session] add missing rollback when freeing a db connection When we let go of a cnxset and give it back to the pool, we need to make sure it's not in the middle of a transaction. We got bitten by a migration where the connection used by admin's repo.connect was not rolled back before attempting the migration, causing a deadlock because it had a lock on a table. This could potentially also be an issue for e.g. hooks or looping tasks that didn't explicitly rollback before calling free_cnxset or moving out of a ensure_cnx_set block.

[debian] add Breaks on cubicweb-bootstrap Need to be versioned once we know which version fixes https://www.cubicweb.org/ticket/3728939

Drop duplicated content in ITreeAdapter docstring

an -> a (misc)

an utf-8 -> a utf-8

an URI -> a URI

an unicode string -> a unicode string

an URL -> a URL

Remove a misleading comment about self.render() behavior. The former comment suggested that View.render called with 'row' or 'col' would set cw_row or cw_col, which is not (anymore ?) accurate. Related to #3696871.

[migractions] add sanity check in rename_relation_type If the relation is still present in the fs schema, we probably shouldn't be renaming it (because it's still in use somewhere, possibly in a different cube). Closes #3608172

[dataimport] Add safety belt on "gen_rtype" in MetaGenerator, closes #3712892 Some cubes may well add to the META_RTYPES set, hence crashing the gen_<somecubemeta> call.

[dataimport] Correctly serialize datetime objects in _create_copyfrom_buffer, closes #3712885

[dataimport] Prevent ucsvreader from skipping the first line when ignore_errors is True (closes #3705791)

[dataimport] Avoid double unicode decoding in ucsvreader (closes #3705752)

[doc] Document the user_data dictionnary content

[debian] break old cubicweb-vcsfile We removed call_service's async argument, which it used.

[services] catch missing group early in register_user Better an assertion than a rql syntax error for such a programming error.

[services] rename register_user kwargs to cwuserkwargs They're attributes/relations for the created CWUser, this makes it clearer.

[services] don't hardcode 'users' group for register_user Let the caller choose which group the user should be in. Related to #3020639 Caveat: this is a possible security hole if untrusted values are allowed.

[sobjects/test] check that register_user properly sets user name and email address Related to #3020639

[server] Refactor Repository.register_user into a CubicWeb service (closes #3020639) [jcr: move commit to the caller; add item in release notes; fix NameErrors]

[migration] set a cnxset before process_script() Not pretty, but I don't have a better idea right now and this at least ensures migration scripts get run in the expected environment and can access sql stuff as before.

[server] make internal_cnx get and keep a connection to the db - internal_session worked that way - it's less surprising for users if their internal connections "just work", rather than having to deal with the cnxset when using low-level APIs Includes a backout of 3f62606c01a2 "[repo] Fix register_user" which is no longer needed. Depend on logilab-database 1.12.1 to avoid errors due to pointless check in python's sqlite3 binding.

[server/session] make commit/rollback obey ensure_cnx_set Inside the ensure_cnx_set context manager, commit and rollback aren't allowed to dispose of the cnxset.
