Function packageFromFunc

riverdbtest/riverdbtest.go:429–437

Gets a "friendly package name" from a fully qualified function name. Most effectively demonstrated by example: - `github.com/riverqueue/river.Test_Client.func1` -> `river` - `github.com/riverqueue/river/internal/jobcompleter.testCompleterWait` -> `jobcompleter` This is then used as a root for con

(funcName string)

// because it's not too long (schemas have a max length of 64 characters), human
// friendly, and won't have any special characters.
func packageFromFunc(funcName string) string {
	var (
		packagePathLastSlashIndex = strings.LastIndex(funcName, "/")        // index of last slash in path, so starting at `/river.Test_Client.func1`
		funcNameFromLastSlash     = funcName[packagePathLastSlashIndex+1:]  // like: `/river.Test_Client.func1`
		packageName, _, _         = strings.Cut(funcNameFromLastSlash, ".") // cut around first dot to extract `river`
	)

	return packageName
}

// TestTxPgx starts a test transaction that's rolled back automatically as the
// test case is cleaning itself up.
