fix(agent): require explicit edges for DataOperations query refs by kabishou11 · Pull Request #19698 · infiniflow/ragflow

kabishou11 · 2026-09-16T03:23:09Z

Summary

Fixes #19697

Per maintainer feedback on workflow semantics: DataOperations may execute only when its upstream producers are explicitly connected on the canvas. A producer@result (or braced) reference in query must not create an implicit scheduler dependency via param_refs(), and a disconnected node must not be allowed to run silently on a stale empty value.

Changes

Remove DataOperations.param_refs() — query strings are no longer a scheduler dependency source.
Validate each component ref in query against get_upstream(); unconnected refs raise a clear ValueError (surfaced as _ERROR).
get_dependency_ids() uses declared inputs plus explicit canvas upstream edges only, so a properly wired producer that shares a batch window with DataOperations is deferred until it finishes (no stale empty read).
Globals without @ (e.g. sys.query) remain allowed without an edge.

Tests

test/unit_test/agent/test_data_operations_batch_readiness.py (real Canvas scheduler):

Unconnected producer@result / {producer@result} in query → rejected (explicit canvas edge error); param_refs() stays empty and producer is not a query-derived dependency.
Connected chain Begin → producer → DataOperations → fresh select_keys payload; start(ops) >= end(producer).
Connected fan-out where producer is also an explicit upstream → edge-based readiness defers ops; no stale empty result.

Verification

pytest --noconftest -o asyncio_default_fixture_loop_scope=function \
  test/unit_test/agent/test_data_operations_batch_readiness.py -q
# 4 passed

DataOperations resolves query entries through Canvas.get_variable_value without exposing them via param_refs(), so the batch scheduler could not hold it behind a sibling producer. Add the override and a real-scheduler regression test. Fixes infiniflow#19697

📝 Walkthrough

DataOperations now validates producer query references against explicit canvas edges. Dependency IDs come from canvas connections instead of query strings. Canvas and query expressions use consistent trimming. Tests cover rejected unconnected references and fresh results from connected producers.

Changes: DataOperations batch readiness

Layer / File(s)	Summary
Query reference contract `agent/component/data_operations.py`, `agent/canvas.py`	`DataOperations` normalizes query entries, validates `producer@result` references against explicit upstream components, and adds `get_dependency_ids()`. Canvas expression normalization uses the same trimming behavior.
Scheduler behavior validation `test/unit_test/agent/test_data_operations_batch_readiness.py`	Adds real-stack tests for unconnected references, braced references, connected chains, fanout graphs, execution ordering, normalization, and fresh producer output.

Thanks for addressing the stale-read issue. However, param_refs() is not the correct fix here. According to our workflow semantics, DataOperations may execute only when its upstream component is explicitly connected on the canvas. A producer@result reference in query must not create an implicit dependency or allow a disconnected node to run. Please validate and reject unconnected references, and keep scheduler dependencies based on explicit canvas edges. Also add a regression test for this case.

Drop param_refs()-based implicit scheduling for DataOperations. Reject producer@result (and braced) query refs whose producer is not an explicit canvas upstream, and keep batch readiness on upstream edges so a properly connected producer is not read while still empty.

kabishou11 · 2026-09-16T05:37:23Z

@buua436 Thanks for the review — agreed that param_refs() was the wrong fix for DataOperations.

Pushed ffb81e4 with the edge-based semantics you described:

Removed DataOperations.param_refs() so a producer@result / braced entry in query no longer creates an implicit scheduler dependency.
Validate & reject unconnected component refs in query: if the producer is not in this node’s explicit canvas upstream, _invoke raises a clear error (requires an explicit canvas edge from '<producer>' …).
Keep readiness on explicit edges: get_dependency_ids() now uses declared inputs + canvas upstream only. That covers both the normal Begin → producer → DataOperations chain (path growth) and the fan-out case where producer is also listed as an upstream while sharing a batch window — ops is deferred until the producer finishes, so there is no stale empty read.
Regression tests in test_data_operations_batch_readiness.py: unconnected (plain + braced) refs are rejected; connected chain and connected fan-out read the fresh payload (4 passed).

Globals without @ (e.g. sys.query) remain allowed without an edge. Prefer this over the CodeRabbit brace-normalization suggestion for param_refs, since that hook is gone for this component.

Trim surrounding spaces before stripping braces so " { producer@result } " resolves to producer@result in DataOperations validation and Canvas variable get/set, matching connected upstream ids.

kabishou11 · 2026-09-16T09:31:34Z

Addressed CodeRabbit whitespace normalize on braced query refs: _normalize_query_ref and Canvas.get_variable_value / set_variable_value now use strip().strip("{}").strip(), so " { producer@result } " resolves to producer@result and stays consistent with connected upstream validation. Covered by unit tests (6 passed).
