Pull request overview
Improves client-v2 error handling by enriching binary reader decode exceptions with context (row/column and elapsed time since last next() call) and by surfacing HTTP error response bodies for common non-ClickHouse errors (e.g., 401/403/404), addressing opaque <Unreadable error message> failures (Issue #2803).
Changes:
- Enhance
RowBinaryreader failures with row/column context and time since lastnext()call. - Parse and include HTTP error response bodies for 401/403/404 (including gzip-encoded bodies) instead of reporting code
0with no message. - Add integration tests covering 404 base-path handling and truncated/chunked binary decode failures.
