[jan-janssen]

Summary by CodeRabbit

• Refactor
  • Updated serialization process to exclude certain data from the task key hash computation, improving consistency and reliability. End-user functionality remains unchanged.

Walkthrough

The serialization process in executorlib/standalone/serialize.py was modified to exclude the resource_dict from the binary data used for task key hash computation. The resource_dict remains in the returned data dictionary but is no longer part of the serialized content passed to cloudpickle.dumps.

Changes

File(s)	Change Summary
executorlib/standalone/serialize.py	Excluded resource_dict from the dictionary passed to cloudpickle.dumps for serialization; resource_dict is still included in the returned data dictionary but omitted from hash computation.

Poem

In the land of pickles and hash,
A resource slipped out in a flash.
Still kept for the task,
But not in the mask,
The hash now runs light and fast—what a dash! 🥕

65-66: Verify that omitting resource_dict from the hash cannot cause task-key collisions

Excluding resource_dict means two invocations that differ only in resource requirements now generate identical task_keys. If any downstream cache/result store keys solely on task_key, those runs may overwrite each other or pick up stale artefacts.

Please confirm:

1. The function output is guaranteed to be resource-independent (e.g. no timing, RNG or side-effects that vary with thread/GPU count).
2. No consumer assumes a unique mapping between task_key and the concrete resources used.

If either assumption fails, consider hashing a minimal, deterministic projection of resource_dict instead of dropping it entirely.
