Complete PR comments on closure-collector mapping support by Ciemaar · Pull Request #18 · Ciemaar/flock

Ciemaar · 2026-05-03T14:47:57Z

This submission completes the refactoring task by fixing remaining code review comments for the Closure Collector mapping support feature:

Prevented mutable default argument bugs in check methods by switching from path=[] to path=None.
Added the required TODO comment indicating that check should eventually verify promise evaluations.
Fixed tests in test_flockdict.py to raise (ClosureCollectorException, FlockException) to correctly reflect changes in the exception hierarchy while preserving legacy flock expectations.
Removed a leftover test artifact (test_iter.py).

PR created automatically by Jules for task 8401923365075099585 started by @Ciemaar

- Replaced mutable default arguments (`path=[]`) with `path=None` in `check` methods across `closure_collector/core.py` and `flock/core.py`. - Added requested `TODO: Confirm that the promises evaluate successfully` to `check` methods. - Restored `_exception_class = FlockException` in `FlockDict` implementation. - Fixed `test_flockdict.py` to expect `ClosureCollectorException` or `FlockException`.

-        return len(self.promises)
+    _list_class: type | None

    def clear_cache(self):


@jules this function doesn't appear to do anything at all, why is it being retained?

Good catch! The clear_cache method here was essentially a no-op that just called super().clear_cache(). I've removed it completely as ClosurePromiseMapping already provides this functionality.

+    """

-class FlockList(PromiseFlock, MutableSequence):
    def __init__(self, inlist: Sequence | None = None, root: FlockBase | None = None):


@jules this function appears to do exactly what the base class does.

Also, use the more general CCBase as the typing for root.

Ciemaar · 2026-05-03T22:41:47Z

-class FlockDict(PromiseFlock, MutableMapping):
-    """
-    A mutable mapping that contains lambdas which will be evaluated when indexed
+    from flock.util import FlockException


@jules this import should be top of file.

+    `closure_collector` backend execution and dependency graph evaluation flow.
+    """

+    _list_class: type | None


@jules I don't think it would be valid to have a None _list_class

Ciemaar · 2026-05-03T22:43:29Z

-    """
+    _exception_class = FlockException

    def __init__(self, indict: list[tuple] | Mapping | None = None, root=None):


@jules I believe the base class does everything this function does and thus this function can be omitted.

You are absolutely correct. The __init__ methods here were just passing arguments to super().__init__ exactly as the base classes would do. I have removed both __init__ methods entirely.

Ciemaar · 2026-05-03T22:44:09Z

-    # def __hash__(self):
-    #     return id(self)
+FlockDict._mapping_class = FlockDict
+FlockDict._list_class = None


@jules shouldn't the _list_class be FlockList?

Yes, absolutely! I've updated both FlockDict._list_class and PromiseFlock._list_class to correctly point to FlockList instead of None.

- Removed redundant `__init__` from `FlockList` and `FlockDict` as requested in PR comments. - Fixed `FlockDict._list_class` to use `FlockList` instead of `None` as requested in PR comments. - Cleaned up obsolete classes `Aggregator` and `MetaAggregator` (superseded by `FlockAggregator`) as well as their tests. - Re-formatted code and sorted imports to fix linting errors.

+                for closure in value.__closure__:

+                        try:
+                            closure.cell_contents.peers.add(self)


@jules make peers _peers across the board.

+            promise = self.promises[key]
+            if hasattr(promise, "shear"):
+                ret[key] = promise.shear(record_errors=record_errors)
+            elif key in self.cache:


@jules isn't this duplicating logic from getitem ? Couldn't we just do ret[key] = self[key] ? Is there any test to demonstrate a functional difference?

Ie we should be able to count on the cache being checked for us if needed

-        Precedence is Mapping, callable, then list
+    def ruleset(self):


@jules add to future features a test that reassembles objects from a pair of dataset + ruleset

+    _list_class: type | None = None  # Assigned below
+
+    def __eq__(self, other):
+        if isinstance(other, list):


@jules is this consistent with how pandas series and other data types in the python ecosystem handle equality?

Remove redundant MutableFlock base class
