The previous commit introduced an optimization to reduce the number of queries and fields fetched when we call `name_search`. But it works much better when the dependencies of `display_name` contain field names used in the calculation (on the same record/model). Then, to improve the performance and the cache coherency, add `depends` and `depends_context` depending on the custom `_compute_display_name`. Add only the first level of dependencies (never traverse relational field) because only these have a positive impact on the previous optimization and the cost is very low (see `modified`). About `depends_context`, we don't include `lang` because (when `_` is used by example) it is unlikely to get the same display_name in the same request with two different lang. closes odoo/odoo#122085 Related: odoo/documentation#4639 Related: odoo/enterprise#42599 Related: odoo/upgrade#4780 Signed-off-by: Raphael Collet <rco@odoo.com>
