# Row 98 (#1592) mutants of scripts/webui-service.sh. Each edit must match exactly once and each runs
|
|
# alone against the test file that holds its case. Every run starts in its own process group and the
|
|
# group is killed when the run ends or times out. The script is restored from the bytes read before
|
|
# the edit, and its sha256 is checked against its start at the end.
|
|
# Usage: mutants.py <worktree> <out.txt> [timeout-seconds]
