The dictionary `_group_by_full` is replaced by a field parameter `group_expand`
that is assigned to the method name. The API of the method has been simplified
as well:
@api.multi
def _read_group_stage_ids(self, domain, read_group_order=None, access_rights_uid=None):
# the stages are given by self.ids (wrong model);
# read_group_order is the order given to read_group() on self;
# return stages.name_get(), {stage.id: stage.fold)
_group_by_full = {'stage_id': _read_group_stage_ids}
is now written:
stage_id = fields.Many2one(..., group_expand='_read_group_stage_ids')
@api.model
def _read_group_stage_ids(self, stages, domain, order):
# stages is a recordset;
# order is the order to use on stages' model;
# return a recordset which is a superset of stages
RecordSets were not preserving order when combined
with AND/OR set operators. Order was lost as well
through mapped().
This caused various recurring "heisenbugs" during
tests executions on runbot, specifically comming
in the test of stock_landed_costs.
Using OrderedSets instead of basic Sets to resolve
these operation avoids the indetermination.
This required an implementation of __or__ / __and__
for OrderedSet.
- As of v10, manifest files should be named `__manifest__.py`
- For backwards-compatibility, __openerp__.py manifest files
will still be supported for the time being
- Limited refactoring, to add support for the 2 different
naming conventions
- All textual references to __openerp_.py updated in
documentation and examples
