[debian] set release date

[entity] add a new `cw_linkable_rql` method * the new method returns the entities that are or may be related to the current one by the relation passed as an argument. Closes #3738011.

[schema] fix buggy composite_rdef_roles and associated test it should only look at rdefs involving the considered entity type. Closes #3712982

[doc] update 3.19 release notes

[login form] Fix BaseLogForm.form_action() The method implementation was calling super() with the wrong class

[migration] move 'entities' table changes from 3.19.0 to bootstrap script The 'mtime' and 'source' columns need to go away before we attempt to do anything else with the repo, otherwise any addition of an entity is going to explode.

[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.
