- Use os.CreateTemp to avoid race conditions with fixed temp filename - Add f.Sync() before close to ensure data durability - Check all fmt.Fprintf errors instead of ignoring them - Preserve original file permissions when overwriting - Handle dir== edge case from filepath.Split - Check os.MkdirAll error - Proper cleanup on all error paths Signed-off-by: luojiyin <luojiyin@hotmail.com> Add documentation comments to WriteSubnetFile Clarify the design choices for atomic file writing: - Explain why CreateTemp is used (defense-in-depth, avoids pre-existing file issues) - Document the single-instance assumption - Note the permission preservation logic Signed-off-by: luojiyin <luojiyin@hotmail.com> Update WriteSubnetFile comment to clarify CreateTemp rationale Remove misleading reference to concurrent writes (K3s is single-instance). Focus on the actual benefits: avoiding stale temp files from crashes, handling unexpected permissions/ownership, and O_EXCL guarantees. Signed-off-by: luojiyin <luojiyin@hotmail.com> Refactor cleanup to use merr.NewErrors for better error aggregation Address review feedback from @brandond to improve error handling: - Change cleanup function to accept error parameter - Use merr.NewErrors to aggregate original error with Close/Remove errors - Simplify error handling with consistent return cleanup(err) pattern Signed-off-by: luojiyin <luojiyin@hotmail.com> Fix Close error handling to preserve original error Add cleanupNoClose helper to avoid double Close and preserve the original Close error when file close fails.
