Add replay to the edg-docker-test tool [] by wchilders-nvidia · Pull Request #246 · edgcpp/compiler

wchilders-nvidia · 2026-10-08T16:08:09Z

This exposes the --replay flag to edg-docker-test to allow users to update recordings more easily when using edg-docker-test.

For instance, if you run:

edg-docker-test --posture=extensive
edg-test-run-diff

and conclude all of the changes are good, you can then run:

edg-docker-test --posture=extensive --replay unexpected -W

to rerun and update only the tests with changes, after this change.

Summary by CodeRabbit

New Features
- Added replay modes for rerunning all failing tests, output mismatches, regressions, or unexpected results.
- Added an option to choose where test-run output is saved.
- Test runs can report their output directory for review tools to open.
Bug Fixes
- If no output directory is reported, review is skipped and the command exits with a status reflecting whether tests passed.

In replay mode, edgy ignores --run-timestamp per it's help txt so the replay output goes to tests/runs//replays/N. edg-docker-test still makes a new timestamp and points AcknowlEDG at it. Locally I ran:

exec edgy --run-timestamp=2026.10.08-13.17.06 --config="edg_x86_64_cp,edg_x86_64" --replay=regress                                                                                                                                                                                                               
  exec edgy-review --root='/edg/workspace/tests/runs/2026.10.08-13.17.06'

edgy-review prints Path does not exist: … and exits 1, and run_acknowledg then calls sys.exit(1).

The fix is a one liner which I have attached as a patch file. It simply skips trying to open the non-existent directory.

Walkthrough

The wrapper accepts replay modes and passes them to edgy. edgy can write its selected run directory to a file. The wrapper uses that directory to launch AcknowlEDG, or skips AcknowlEDG when no directory is reported.

Changes: Test replay and review flow

Layer / File(s)	Summary
Replay mode configuration `dev_tools/bin/edg-docker-test`	The wrapper reads replay mode from command-line or posture configuration and adds the selected mode to edgy arguments.
Run-directory selection and reporting `dev_tools/bin/edgy`	edgy supports an explicit output directory, reports the selected run directory through `EDGY_RUN_DIR_FILE`, and skips automatic cleanup when an explicit output directory is set.
Wrapper invocation and AcknowlEDG handoff `dev_tools/bin/edg-docker-test`	The wrapper maps generated files to absolute container paths and sets `EDGY_RUN_DIR_FILE`. It passes the reported directory to AcknowlEDG, or skips AcknowlEDG if no directory is reported.

Review details

Systems and components

observed — dev_tools (service) was modified; 2 changed files map to changed impact.

Before / after behavior

observed — Modified behavior in dev_tools/bin/edg-docker-test: The imports add PurePath and remove datetime; a RUN_DIR_FILE_PATH constant names the file used to receive edgy’s run directory.
observed — Modified behavior in dev_tools/bin/edg-docker-test: Argument parsing adds --replay, accepting the four listed replay modes and defaulting to None.
observed — Modified behavior in dev_tools/bin/edg-docker-test: TestRunPosture.__init__ gains an optional replay_mode parameter, defaulting to None.
observed — Modified behavior in dev_tools/bin/edg-docker-test: The posture stores the supplied replay mode in self.replay_mode.

the effective posture.keep_test_results policy before enabling replay. Reject
replay when that policy is false, including when replay is requested through CLI
arguments or posture-file replay_mode.
