[i18n] use named substitution to avoid gettext warnings

[dataimport] print transaction id when we get one

[cleanup] add some notes

[optimisation] _select_best is used very intensivly. Peanuts optimization may count :)

[optimization] traced_selection is used very intensively in debug mode optimizing it is worth the pain. Basically : don't do stuff unnecessary when we don't trace anything.

[optimization] improve massive write performance by optimizing hooks selection profiling on some massive deletion showed up that 2/3 of the time was spent in hooks selection. Those changes make it much more acceptable (through selection is still not negligeable): * use one registry for each event, so we've much less hooks to check when emiting an event as well as no more need for the match_event selector. This required ability to put one appobject into several registries, using a __registries__ class attribute. * check for deprecated .enabled at registry initialization time instead of at selection time A very simple HooksManager class has been reintroduce to choose the right registry on call_hooks. Those optimisations leads to a ~x3 factor of time necessary to delete 16000 entities.

[upgrade] after upgrade, fork command to start instance avoid grave uicfg pb (explicit rules all removed...)

merge

[repo creation] removing existing entities of 'single' cardinality relatino should be considered as 'activeintegrity' hook. Also don't disable that category during repo creation to avoid pb such as two default workflows for one entity types

merge

handle Service Close request correctly (closes #736039) The windows event self._stop_event was not used, and twisted was not getting a chance of terminating cleanly by calling its shutdown event handlers (which would eventually call pyro_unregister). Fixed by calling reactor.stop()

[js form validation] fix case where we've None/null keys in the errors dictionnary

[cleanup] exists imported, use it

[form] CompoundField should not return itself in actual_fields, this avoid error on iliane with 3.7.2 where it's marked as required (from the schema) while value are provided by subfields

[repo] we want a hooks manager and hooks initialized event on quick start (we trigger events such as server_backup / server_restore for instance)

[distribution] sql extensions files now have proper extension, fix manifest file

backport stable

[events manager] onevent decorator may be given extra arguments to give to em.bind

[cleanup] some notes

[reload] on registry reloading, we should change class of users of opened session

[appobject imports] don't include __init__ in package's name. See comment for more info

[rset] cubes such as iliane hi-jack rset description by poping some lines from it. Handle this on RepeatList

[undo] basic support for undoing of entity creation / relation addition

[undo] init entity cache when undoing an entity deletion

[undo] consistent is/is_instance_of processing

[repo] don't need rset description on those queries

[cleanup] style fixes, add nodes, 0.2 cents refactorings

[undo] during undoing, call hooks in the [active]integrity and undo categories

[repo] refactor fti operation to use set_operation and a single operation whatever the number of entities to ft index

[querier] introduce RepeatList class, used to optimize size of data returned for result set description When rql query has no ambiguity, we used to return the same description * N where N is the size of the result set. Returning RepeatList class avoid that multiplication. According to quick benchmark this improve performance for result set whose size is ~ > 50, has very small penalty for rset < 50, and in any case improve the size of data to be transfered over the network through pyro connection.

[repo] on add entity, set cache as soon as possible + fill type/source cache

[repo] more efficient eid cache operations handling based on set_operation; refactor * split CleanupEidTypeCache operation into one operation for deleted eids and another for added eids, and put them in cw.server.hook * for consistency, move fti unindexing handling from the repository to the system source * handling of deleted eids is done in plan execution (ssplanner), no needs to redo it in *delete_info -> no more need for _prepare_delete_info method, killed
