Greptile SummaryThe PR improves remote-training status handling, dry-run configuration validation, Windows test portability, and shipping of local datasets referenced by configuration.
Confidence Score: 4/5The PR is not yet safe to merge because shipping a config-only local dataset still replaces the complete configured dataset list on the remote invocation. The remote runner receives one detected local file as a positional dataset, and that positional value overrides the configured dataset array, so remote training silently omits every remaining dataset entry.

| Filename | Overview |
|---|---|
| src/praisonai-train/praisonai_train/cli/commands/train.py | Adds remote dry-run resolution, failure-prefix handling, and config-only dataset shipping, but the single positional dataset still replaces multi-entry configurations. |
| src/praisonai-train/praisonai_train/remote/settings.py | Correctly distinguishes absent or null remote settings from malformed falsey non-mapping values. |
| src/praisonai-train/tests/unit/test_remote_dispatch.py | Improves status-vocabulary and dataset-shipping coverage, though it does not preserve or verify multi-entry dataset configurations. |
| src/praisonai-train/tests/unit/test_remote_parity.py | Covers malformed falsey remote blocks and valid omitted or null configurations. |
| src/praisonai-desktop/engine/test_portability.py | Makes teardown safe when platform-specific setup skips before temporary-path initialization. |

There was a problem hiding this comment.
When a remote config names a relative local dataset and the CLI runs outside the config directory, _local_dataset_in checks the path against the process working directory instead. The file is not shipped, so the remote trainer interprets the unavailable path as a dataset identifier and aborts before training.

Ship every local file referenced by data_files.
When data_files is a mapping, _local_dataset_in ignores it because the candidate is not a string. When it is a multi-file list, _local_dataset_in selects only the first file. _write_shipped_config preserves the remaining local paths, so the remote trainer can fail when it resolves those paths on the remote host.
Extend the remote transfer contract to ship and rewrite all local data_files entries, or reject unsupported configurations before starting the run. Add mapping and multi-file regression cases.

When a remote configuration contains multiple dataset entries or multiple data_files, _local_dataset_in selects one local file and the runner passes it as the positional dataset argument. That argument replaces the complete configured dataset list, causing the remote run to silently omit the remaining local or Hub datasets.

- Detect failed status by prefix: runner.status() returns 'failed (exit N)', so the equality check reported failed remote runs as success. - Ship a dataset named only in --config when it is a local file, so the remote process is not handed a path that exists only locally. - Resolve and validate the remote block in --dry-run so the preview matches the real dispatch and bad settings are caught before renting a GPU. - Reject falsey non-mapping remote values ([], '', false) instead of quietly treating them as train-locally. - Assert typer.Exit in the no-remote dispatch test rather than swallowing every exception; skip the POSIX-only keyring tests on Windows. Co-authored-by: Mervin Praison <MervinPraison@users.noreply.github.com>
The triage bot fixed a real bug of mine: the dispatch compared `state == "failed"` while status() returns `"failed (exit N)"`, so a remote run that failed was reported as a success. My test did not catch it because my fake returned exactly `"failed"` -- and `"done"` for success, which the runner never returns either. The fake agreed with the bug, so the test passed and the code was wrong. That is the same defect as the code it was meant to check, one level up. The fake now speaks the runner's actual vocabulary -- completed, running, unknown, `failed (exit N)` -- and a test reads runner.py from disk and asserts those spellings still exist, so the fake cannot quietly drift from the thing it stands in for. Deleting `failed (exit` from the runner now fails the dispatch tests. Two test-harness repairs alongside it. `monkeypatch.setattr(train_cmd, "import_code_module", ...)` never intercepted anything: train_llm imports that name inside the function body, so the patch has to be on praisonai_train._code_bridge, where the lookup happens. And the vocabulary test read RemoteRunner through the module -- which the autouse fixture has already replaced with the fake, so it would have asserted that the fake agrees with itself. Three mutations, three caught, including restoring the equality comparison. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The remote dispatch fallback only recognised a dataset given as a bare
string, but the trainer's canonical shape is a list of mappings and it
loads any name/data_files that exists on disk. A config using
`dataset: [{name: ./local.json}]` therefore had its file left behind, and
the remote run failed on a path that existed only on the launching machine.
_local_dataset_in now inspects both forms, mirroring how the trainer
resolves a local file, and returns the first local dataset to ship.

PR #4450 merged at 11:07. These three commits were pushed to the same branch
after that, so they never landed — and one of them is a real bug.
maincurrently reports a failed remote run as a successRemoteRunner.status()returns"failed (exit N)", never a bare"failed".The comparison never matches, so a fine-tune that died is reported as having
succeeded. Fixed by matching the prefix.
My test didn't catch it because my fake returned exactly
"failed"— and"done"for success, which the runner never returns either. The fake agreedwith the bug. It now speaks the runner's real vocabulary (
completed,running,unknown,failed (exit N)), and a test readsrunner.pyfrom diskto assert those spellings still exist, so the stand-in cannot drift from the
thing it stands in for.
main's desktop CI is redengine (windows-latest)fails on three of my own tests. They put a#!/bin/shscript on PATH to stand in forsecurity/secret-tool, whichWindows cannot execute — and those two stores are macOS-only and Linux-only
anyway. Windows uses
DpapiSecretStore, which does not have the defectthese tests exist for: its delete is a rewrite of the whole blob, and a failed
write is already caught.
Skipped explicitly, with the reason in the skip.
