no-search-all (W8163)

search([]) without a limit loads every record.

What it does

Reports search() and search_read() with an empty domain and no limit or count inside model methods, including a domain variable assigned [] in the same method and never extended before the call.

Why is this bad?

The query loads every record of the model, which gets slower as the database grows and can exhaust the worker’s memory.

Example

partners = self.env["res.partner"].search([])

Use instead: add a domain, or a limit when any record will do.

Configuration

Models whose number of records is small by design can be allowed:

[tool.odoo-lint.rules.no-search-all]
# res.company: one per company (13 in production). machine.machine is not
# listed: 1,554 records and growing.
bounded-models = ["res.company"]

A search on self.env["res.company"] (also after .sudo(), .with_context(...) and the like) is then not reported.

Count the records in a production database before listing a model, and note the reason next to it: the name does not tell. Two models of the same module can differ by orders of magnitude, and a model that is small today may not stay small. There is no default list for that reason.
