* s3tables, iceberg: log client refusals at V(1), not ERROR Requests the S3 Tables and Iceberg REST APIs correctly refuse with a 4xx (access denied, not authorized, no such namespace, already exists, not empty, a commit conflict) were logged with glog.Errorf, so a client probing for what it may do, or retrying an optimistic commit, filled the ERROR log and hid real faults from anyone alerting on it. - s3tables: HandleRequest wraps the ResponseWriter in a statusRecorder (with Unwrap for http.ResponseController) and logs a handler error by the status it answered: 4xx at V(1) as "<op> refused (<status>)", 5xx or no status at ERROR as before. - s3tables: the "handleCreateNamespace called" trace moves from ERROR to V(3). - iceberg: writeManagerError's mapping is split into classifyManagerError, shared with a new logManagerError that logs 4xx-mapped errors at V(1) and everything else at ERROR; used by CreateNamespace, CommitTable and CommitTransaction. - storage: loading a remote-tier volume logged "readSuperBlock remote volume N: <nil>" at ERROR even when the read succeeded; it is now logged only when there is an error. Tests: TestRequestRefusedWith4xxIsNotLoggedAsError, TestLogRequestErrorByStatus, TestStatusRecorderKeepsTheFirstStatus, TestStatusRecorderUnwrapsForResponseController, TestNoTraceLoggedAtErrorLevel (fails on master on the CreateNamespace trace), TestLogManagerErrorRefusalsAreNotErrors, TestRemoteSuperBlockLogOnlyOnError. * s3tables: do not log a malformed CreateNamespace body at ERROR handleCreateNamespace logged a body it could not decode at ERROR before answering 400; the dispatcher already logs that refusal once at V(1). Also drop statusRecorder.Flush: it made the recorder an http.Flusher even over a writer that cannot flush, so http.NewResponseController reported success instead of ErrNotSupported. Unwrap already lets the controller reach the wrapped writer. * iceberg: require exactly one log line per classified manager error The test accepted a refusal that produced no log, or both logs. Require one V(1) refusal and no ERROR for a 4xx, and the reverse for a fault. --------- Co-authored-by: Javier de la Torre <jatorre@lakehousebox.com>
