Apply standardized error handling patterns across your codebase for improved reliability and debugging. For new code, use the `absl` error types instead of `tsl::errors` and include descriptive error messages with context. Key practices: 1. Use `absl` error types with `absl::StrCat` for error messages 2. Perform validation checks early in functions 3. Use appropriate error handling mechanisms for your function's return type 4. Return `StatusOr` for operations that can fail instead of raw values ```cpp // Instead of: return errors::InvalidArgument("Invalid shape: ", shape.DebugString()); // Use: return absl::InvalidArgumentError( absl::StrCat("Invalid shape: ", shape.DebugString())); // For void functions, use the proper macro: OP_REQUIRES(ctx, input.shape().dim_size(i) != 0, absl::InvalidArgumentError("Invalid input: Dimension cannot be 0.")); // For functions that can fail, return StatusOr: StatusOr GetDeviceNameFromStreamDeviceName(const string& stream_name) { if (!IsValidStreamName(stream_name)) { return absl::InvalidArgumentError("Invalid stream device name"); } return ParsedName; } ```
