ReadwriteFehler

ReadwriteFehler is a term used in computing to describe an error condition that occurs during a combined read and write operation on a data stream or storage resource. The term is not standardized, but it is used in documentation and logs to signal situations where the operation does not complete as intended, potentially leaving data in an inconsistent state.

Typical scenarios include partial reads or writes, interrupted system calls (for example due to signals or timeouts), non-blocking I/O, and resource constraints such as disk full or insufficient permissions. In network communications, a socket may deliver only part of a payload or report an error during a write, yielding a readwriteFehler.

Handling involves validating how many bytes were actually transferred, issuing retries with backoff, or switching to safer patterns such as writing to a temporary file and atomically replacing the target, or using transactional or end-to-end checksums to verify integrity. Robust libraries treat readwriteFehler as recoverable only if the downstream resource can be retried or compensated for; otherwise the error should be propagated with context for diagnostics.

Prevention focuses on clear API contracts, avoiding mixed buffered/unbuffered access, ensuring proper synchronization, and employing atomic operations where possible. Adequate error logging and metrics help operators detect patterns that indicate systemic issues, such as flaky storage or network problems.
