264-267: Update Docstring to Reflect Parameter Change

The parameter data in get_line_cnt_from_cols is now a bytes object containing file contents, but the docstring still describes it as Path to file. Please update the docstring to accurately reflect the parameter's purpose and type.

Line range hint 180-189: Handle Possible Exceptions from read_with_timeout

The call to file_obj.read_with_timeout() in get_suggestions_from_patch may raise exceptions such as FileIOTimeout or OSError. Without exception handling, unhandled exceptions could cause the application to crash. Please add appropriate exception handling to manage potential errors during file reading.

Apply this diff to add exception handling:

180     try:
181         patch = Patch.create_from(
182             file_obj.read_with_timeout(),
183             self.patched,
184             file_obj.name,
185             file_obj.name,
186             context_lines=0,  # exclude any surrounding unchanged lines
187             flag=INDENT_HEURISTIC,
188         )
189     except (FileIOTimeout, OSError) as e:
190         logger.error("Error reading file %s: %s", file_obj.name, e)
191         return  # Handle the exception as appropriate

249-249: Document timeout behavior and duration

The change to use read_with_timeout() improves reliability, but the timeout behavior should be documented. Consider adding a comment explaining the timeout duration and what happens when a timeout occurs.

+        # Read file with N-second timeout to prevent hanging on file operations
         original_buf = file_obj.read_with_timeout()

162-193: LGTM! Consider documenting the sleep interval.

The implementation correctly handles timeouts using monotonic clock, provides proper error handling, and uses appropriate file operations. The 1ms sleep interval is a good balance between CPU usage and responsiveness.

Consider adding a comment explaining the choice of 1ms sleep interval:

 else:  # pragma: no cover
+    # Sleep for 1ms to prevent busy-waiting while maintaining responsiveness
     time.sleep(0.001)

Line range hint 269-282: Update docstring to match parameter changes.

The docstring still references file_path but the parameter has been changed to data.

Apply this diff to fix the documentation:

-    :param data: Path to file.
+    :param data: Bytes content to analyze.
     :param offset: The byte offset to translate

Line range hint 162-282: Solid implementation addressing file I/O reliability.

The new timeout-oriented functions effectively address the file I/O issues from #129 by:

1. Implementing robust timeout handling using monotonic clock
2. Providing proper error recovery mechanisms
3. Preventing busy-waiting with reasonable sleep intervals
4. Maintaining clean separation of concerns between read and read-write operations

The caching mechanism for file bytes (through the modified get_line_cnt_from_cols) reduces unnecessary file operations, improving overall performance.

Learning: In the `cpp_linter/common_fs/__init__.py` file, avoid refactoring the `read_with_timeout` and `read_write_with_timeout` methods into a shared helper function due to potential runtime overhead and the risk of unsafely passing open file handles.

162-194: Enhance error message and exception handling.

The implementation is solid with good timeout management using monotonic clock and proper error prevention. However, consider these improvements:

1. Make the timeout error message more descriptive by including the filename
2. Consider catching specific OSError types (like PermissionError) separately

Apply this diff to enhance the error handling:

 exception: Union[OSError, FileIOTimeout] = FileIOTimeout(
-    "Failed to read from file within %d seconds"
-    % round(timeout_ns / 1_000_000_000, 2)
+    f"Failed to read from file '{self.name}' within {round(timeout_ns / 1_000_000_000, 2)} seconds"
 )

---

195-240: Consider adding backup mechanism and enhance error message.

The implementation is robust with proper atomic read-write operations and file truncation. Consider these enhancements:

1. Add a backup mechanism before writing to prevent data loss in case of failure
2. Make the timeout error message more descriptive

Apply this diff to enhance the implementation:

 exception: Union[OSError, FileIOTimeout] = FileIOTimeout(
-    "Failed to read then write to file within %d seconds"
-    % round(timeout_ns / 1_000_000_000, 2)
+    f"Failed to read then write to file '{self.name}' within {round(timeout_ns / 1_000_000_000, 2)} seconds"
 )

Consider adding this backup mechanism before writing:

import shutil
import tempfile

def _backup_file(self):
    """Create a backup of the file before writing."""
    backup_path = Path(tempfile.gettempdir()) / f"{Path(self.name).name}.bak"
    shutil.copy2(self.name, backup_path)
    return backup_path
