GitHub Issue #11979 + +## Problem Summary + +Kubeflow Pipelines v2 has a critical bug where DAG (Directed Acyclic Graph) executions get stuck in `RUNNING` state and never transition to `COMPLETE`, causing pipeline runs to hang indefinitely. This affects two main constructs: + +1. **ParallelFor Loops**: DAGs representing parallel iterations do not complete even when all iterations finish +2. **Conditional Constructs**: DAGs representing if/else branches do not complete, especially when conditions evaluate to false (resulting in 0 executed tasks) + +## GitHub Issue + +**Link**: https://github.com/kubeflow/pipelines/issues/11979 + +**Core Issue**: DAG status propagation failures in Kubeflow Pipelines v2 backend for ParallelFor and Conditional constructs, causing pipeline runs to hang in RUNNING state instead of completing. + +## Observed Symptoms + +### Integration Test Failures +- `/backend/test/integration/dag_status_parallel_for_test.go` - Tests fail because ParallelFor DAGs remain in RUNNING state +- `/backend/test/integration/dag_status_conditional_test.go` - Tests fail because Conditional DAGs remain in RUNNING state +- `/backend/test/integration/dag_status_nested_test.go` - Tests fail because nested DAG structures don't complete properly + +### Real-World Impact +- Pipeline runs hang indefinitely in RUNNING state +- Users cannot determine if pipelines have actually completed +- No automatic cleanup or resource release +- Affects both simple and complex pipeline structures + +## Test Evidence + +### ParallelFor Test Failures +From `dag_status_parallel_for_test.go`, we expect: +- `iteration_count=3, total_dag_tasks=3` ✅ (counting works) +- DAG state transitions from RUNNING → COMPLETE ❌ (stuck in RUNNING) + +### Conditional Test Failures +From `dag_status_conditional_test.go`, we expect: +- Simple If (false): 0 branches execute, DAG should complete ❌ (stuck in RUNNING) +- Simple If (true): 1 branch executes, DAG should complete ❌ (stuck in RUNNING) +- Complex conditionals: Executed branches complete, DAG should complete ❌ (stuck in RUNNING) + +## Architecture Context + +### Key Components +- **MLMD (ML Metadata)**: Stores execution state and properties +- **Persistence Agent**: Monitors workflow state and updates MLMD +- **DAG Driver**: Creates DAG executions and sets initial properties +- **API Server**: Orchestrates pipeline execution + +### DAG Hierarchy +```

Unit Tests**: Build focused unit tests for faster iteration (located in `dag_completion_test.go`) +3. **Verify Unit Tests**: Before running slow integration tests, ensure unit tests are comprehensive and pass +4. **Root Cause Analysis**: Identify why DAGs remain in RUNNING state +5. **Incremental Fixes**: Test changes against unit tests first, then integration tests + +## Investigation Questions + +1. **Where is DAG completion logic?** What determines when a DAG transitions from RUNNING → COMPLETE? +2. **How are ParallelFor DAGs supposed to complete?** What should trigger completion for parent vs iteration DAGs? +3. **How are Conditional DAGs supposed to complete?** What happens when 0, 1, or multiple branches execute? +4. **Status Propagation**: How should child DAG completion affect parent DAG state? +5. **Task Counting**: How is `total_dag_tasks` supposed to be calculated for different DAG types? + +## Test Files Detailed Analysis + +### ParallelFor Test (`dag_status_parallel_for_test.go`) +**Purpose**: Validates that ParallelFor DAG executions complete properly when all iterations finish. + +**Key Scenarios**: +- Creates a ParallelFor construct with 3 iterations +- Each iteration should run independently and complete +- Parent ParallelFor DAG should complete when all child iteration DAGs finish +- Tests `iteration_count=3, total_dag_tasks=3` calculation correctness +- **Current Bug**: DAGs remain stuck in RUNNING state instead of transitioning to COMPLETE + +### Conditional Test (`dag_status_conditional_test.go`) +**Purpose**: Validates that Conditional DAG executions complete properly for different branch scenarios. + +**Key Scenarios**: +- **Simple If (true)**: Condition evaluates to true, if-branch executes, DAG should complete +- **Simple If (false)**: Condition evaluates to false, no branches execute, DAG should complete with 0 tasks +- **If/Else (true)**: Condition true, if-branch executes, else-branch skipped, DAG completes +- **If/Else (false)**: Condition false, if-branch skipped, else-branch executes, DAG completes +- **Complex conditionals**: Multiple branches (if/elif/else), only executed branches count toward completion +- **Current Bug**: DAGs remain stuck in RUNNING state regardless of branch execution outcomes + +### Nested Test (`dag_status_nested_test.go`) +**Purpose**: Validates that nested DAG structures (pipelines within pipelines) update status correctly across hierarchy levels. + +**Key Scenarios**: +- **Simple Nested**: Parent pipeline contains child pipeline, both should complete properly +- **Nested ParallelFor**: Parent pipeline with nested ParallelFor constructs, completion should propagate up +- **Nested Conditional**: Parent pipeline with nested conditional constructs, status should update correctly +- **Deep Nesting**: Multiple levels of nesting, status propagation should work through all levels +- **Current Bug**: Parent DAGs don't account for nested child pipeline tasks in `total_dag_tasks` calculation, causing completion logic failures + +**Expected Behavior**: +- Child pipeline DAGs complete correctly (have proper task counting) +- Parent DAGs should include nested child pipeline tasks in their completion calculations +- Status updates should propagate up the DAG hierarchy when child structures complete +- Test expects parent DAGs to have `total_dag_tasks >= 5` (parent tasks + child pipeline tasks) + +## Success Criteria + +- [ ] ParallelFor DAGs complete when all iterations finish +- [ ] Conditional DAGs complete when branches finish (including 0-task cases) +- [ ] Nested DAGs complete properly with correct task counting across hierarchy levels +- [ ] Status propagates correctly up DAG hierarchies +- [ ] No regression in existing functionality +- [ ] Pipeline runs complete instead of hanging indefinitely +- [ ] All three integration tests pass consistently \ No newline at end of file diff --git a/backend/src/v2/driver/dag.go
