bulk_create batch_size param overrides the compatible batch size calculation
Description
(last modified by Ahmet Kucuk)
At this line: https://github.com/django/django/blob/stable/2.2.x/django/db/models/query.py#L1197
batch_size param overrides compatible batch size calculation. This looks like a bug as bulk_update properly picks the minimum of two:
https://github.com/django/django/blob/stable/2.2.x/django/db/models/query.py#L504
I suggest using similar
batch_size = min(batch_size, max_batch_size) if batch_size else max_batch_size
logic in bulk_create as well. I am happy to open a PR for it.
Work only inside this repository checkout. Make the code change the task
describes, keeping the diff focused — no drive-by refactors.
When you are done, leave your changes committed or in the working tree;
they are collected automatically.
Stay on this snapshot checkout (`task/ycb_django_pr11951`). Never checkout, pull, or rebase onto `main`. That branch is a README-only orphan.
Stay on this HEAD. Do not fetch another default branch. Push only on the Cursor-created `crazy-cursor/…` side branch from this HEAD.
Some past runs of this task were launched with a different prompt (the prompt template changed since, or those runs predate this benchmark's stored prompt). Each run persists the exact prompt it sent at launch — that per-launch record is the audit trail; this page shows only the current one.
