[testlib, realdb] we should close connections prior to create a new db using current db as template

[migration] this is needed to avoid pb with yams 0.33 / cw < 3.13

[sync schema hooks] consider etype name map before trying to update in-memory schema

[repository] refactor and optimize '?1' relation handling * only skip auto remove if activeintegrity is explicitly disabled * do it even for inlined relation, so hooks are properly called * on entity creation, only cleanup what's needed

[session] deprecates schema_rproperty in favor of more optimized rtype_eids_rdef which return the rdef (so reusable to gather other data)

[repository] refactor/cleanup entity deletion methods * kill unused Repository.delete_info_multi (no leading _) * kill unnecessary system_source.delete_info (almost no benefit over delete_info_multi) * stop giving entities list *and* extid list, gather them from the entity when needed * move pending eids handling into glob_delete_entities, so one can call it directly without worrying about that

[repository] new hook selector according to configuration's repairing flag

[pyrorql] don't display traceback on connection error

[data hook] new .union operation on DataOperationMixIn, only when container is a set, not a list
