Function RunCleaner

coderd/database/dbtestutil/cleaner.go:193–210

RunCleaner runs the test database cleaning process. It takes no arguments but uses stdio and environment variables for its operation. The cleaner is designed to run in a separate process from the main test suite, connected over stdio. If the main test process ends (panics, times out, or is killed)

()

// process ends (panics, times out, or is killed) without explicitly discarding the databases it clones, the cleaner
// removes them so they don't leak beyond the test session. c.f. https://github.com/coder/internal/issues/927

	// we want to ignore the signal and do our cleaning.
