Poorvankbhatia opened a new pull request, #26843:
URL: https://github.com/apache/flink/pull/26843
## What is the purpose of the change
This PR migrates ManuallyClosedSourceFunction in
CoordinatorEventsToStreamOperatorRecipientExactlyOnceITCase from the deprecated
legacy SourceFunction API to the modern FLIP-27 Source API
## Brief change log
- Removed ManuallyClosedSourceFunction class that implemented the
deprecated SourceFunction interface
- Note: DataGeneratorSource cannot be used directly as this source emits
no data and requires external control via static flags for test coordination
## Verifying this change
Existing tests in
CoordinatorEventsToStreamOperatorRecipientExactlyOnceITCase already cover this
change:
- testCheckpoint() - verifies operator coordinator events work correctly
with aligned checkpoints
- testUnalignedCheckpoint() - verifies operator coordinator events work
correctly with unaligned checkpoints
- testCheckpointWithSubtaskFailure() - verifies exactly-once semantics
during subtask failures
- testUnalignedCheckpointWithSubtaskFailure() - verifies exactly-once
semantics during subtask failures with unaligned checkpoints
All tests pass.
