We need to process the post-insert IDs earlier: Not after executeInserts() has been finished, but rather during the execution. → #10743 |

This refactoring does two things: * We can avoid collecting the post insert IDs in a cumbersome array structure that will be returned by the EntityPersisters and processed by the UoW right after. Instead, use a more expressive API: Make the EntityPersisters tell the UoW about the IDs immediately. * IDs will be available in inserted entities a tad sooner. That may help to resolve doctrine#10735, where we can use the IDs to skip extra updates.

…hen using application-provided IDs This change improves scheduling of extra updates in the `BasicEntityPersister`. Extra updates can be avoided when * the referred-to entity has already been inserted during the current insert batch/transaction * we have a self-referencing entity with application-provided ID values (the `NONE` generator strategy). As a corollary, with this change applications that provide their own IDs can define self-referencing associations as not NULLable. I am considering this a bugfix since the ORM previously executed additional queries that were not strictly necessary, and that required users to work with NULLable columns where conceptually a non-NULLable column would be valid and more expressive. One caveat, though: In the absence of entity-level commit ordering (doctrine#10547), it is not guaranteed that entities with self-references (at the class level) will be inserted in a suitable order. The order depends on the sequence in which the entities were added with `persist()`. Fixes doctrine#7877, closes doctrine#7882. Co-authored-by: Sylvain Fabre <[email protected]>

…cation-provided IDs This excludes such associations from the commit order computation, since the foreign key constraint will be satisfied when inserting the row. See doctrine#10735 for more details about this edge case.
