[FIX] mrp: installation on very large inventories Before this commit, installation of MRP in a database with 4.8M stock.move + 4.8M stock.move.line was not possible at all. The process lasted for a very long time (>90 min in our tests) then eventually failed after using the whole RAM of your server. This commit allows installing MRP in databases with large stock.move /stock.move.line tables by bootstrapping the slow parts in SQL. (A more general fix regarding the time complexity of some parts of the prefetching algorithm is coming later in 13.0-init-computed-fields-rco) ----- [FIX] mrp: more Voodoo magic It appears that if you update a record more than once in the same PostgreSQL transaction, PostgreSQL is going to re-check all the constraints on the table. ** THIS IS THE PART WHERE THE BLACK MAGIC HAPPENS ** We combine the setting of the default value of stock.move.unit_factor in the same UPDATE query to avoid the constraint re-check; it saves approximately 60% of the SQL running time in my case. ** ... AND NOW YOU CAN SAY: WHAT THE F...?! ** Thanks to @rco-odoo for the tip; he knows it from the wise @nseinlet. ----- opw-[2281585](https://www.odoo.com/web?debug=1#id=2281585&action=3531&model=project.task&view_type=form&cids=&menu_id=4720) closes odoo/odoo#57946 Forward-port-of: odoo/odoo#57850 Signed-off-by: Richard Mathot (rim) <rim@openerp.com>
