From df2fbdfa553526062e5234286f60bd643941298a Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Mon, 26 Jan 2026 10:51:23 +0100 Subject: odb: introduce `odb_for_each_object()` Introduce a new function `odb_for_each_object()` that knows to iterate through all objects part of a given object database. This function is essentially a simple wrapper around the object database sources. Subsequent commits will adapt callers to use this new function.
