ChangesExternalAction logging
Estimated code review effort: 2 (Simple) | ~10 minutes Mergeability Score: 🔵 Low · up to The change improves subprocess error diagnostics, but actions with the same executable name can still overwrite each other’s logs when they start within the same millisecond, potentially losing failure details. The PR is mergeable with explicit owner awareness or follow-up to make log filenames collision-resistant. Possibly related PRs

Make each log filename collision-resistant.
Line 262 removes microsecond precision. Two actions with the same exe_name can start in the same millisecond and receive the same path. Line 300 then opens that path with "w" and replaces the earlier action log.
Use an untruncated timestamp together with a UUID, or create the file atomically and retry on FileExistsError. This preserves a separate log for each action.

Description
If the subprocess run by an
ExternalActioninstance times out or fails to start,pytest.failis called without writing a log file for the subprocess. This PR ensures that the log file is written even when encountering an error.Checklist
