Before this commit, during a module uninstall, module data would be unlinked in a record-by-record basis, this was done this way for two elementary reasons: - To guarantee an unlink order, as some module data being deleted might only be deleted if some other module data has already been deleted. e.g. [a, b, c, a] -> we could batch unlink both `a` in the list, however the second `a` could depend on the unlink of either b or c, making the groupby erroneous. - To create a savepoint before every module data unlink (record), so that in case it fails, we can simply skip it and proceed with the uninstall. After this commit, batch unlink of module data is now possible without losing the aforementioned key features. - The first problem is fixed by using `itertools.groupby`, which will group **adjacent** data of the same type and unlinks them all in batch while guaranteeing correct unlink order. e.g. [a, a, a, b, b, c, a, c, c, c] -> this will unlink in batches of [a, a, a], [b, b], [c], [a], [c, c, c] - The second problem is fixed by making a savepoint per batch, if a single element of the batch fails and the recordset contains more than one element, we split the recordset into two and we repeat the unlink process recursively until we weed out the undeletable record Real world example: l10n_mx_edi takes 20min to uninstall because it contains a lot of master data (~55k records), with this patch the uninstall takes a measly 20s. It should generally reduce the uninstallation time for all modules, but those with lots of master data will see greater benefits in terms of time. opw-2025895 closes odoo/odoo#34435 Signed-off-by: Raphael Collet (rco) <rco@openerp.com>
