reverted a broken AI refractor, improved previous method of file checking #1863
Conversation
…king Now symlink directories with . wont break anything.
WalkthroughThe pull request introduces modifications to the The new implementation removes the previous empty filepath check and introduces a more complex mechanism for determining symlink status. The function now calculates filepath length, identifies the last directory separator, and performs a backward iteration to detect file extensions. The core change involves a new approach to identifying potential symlinks based on file extension positioning, with a default return of These modifications represent a significant restructuring of the symlink detection mechanism, changing the control flow and extension evaluation strategy for file identification on Windows systems. ✨ Finishing Touches

41-41: Improve the comment to better explain the implementation rationale.The current comment "need to over-engineer a bit" is vague and doesn't explain why this complexity is necessary. Consider documenting the specific Windows limitations and the approach taken to work around them.
- // so we need to over-engineer a bit + // Windows doesn't expose symlink target type through fileInfo, so we need to + // differentiate between file and directory symlinks by analyzing the path format. + // This helps handle special cases like dot-prefixed directory symlinks.

43-53: 🛠️ Refactor suggestionAddress potential edge cases in the symlink detection logic.
While the implementation fixes the dot-prefixed directory issue, there are some potential edge cases to consider:
- Missing bounds check for
i-1at line 47- Windows paths can contain forward slashes, but only backslashes are checked
- Multiple dots in the path might lead to incorrect detection
Consider this improved implementation:
- Length, dirIndex := len(filepath)-1, strings.LastIndex(filepath, "\\") - for i := Length; i > dirIndex; i-- { + Length := len(filepath) + if Length == 0 { + return false + } + // Handle both forward and backward slashes + dirIndex := strings.LastIndexAny(filepath, "\\/") + if dirIndex == -1 { + dirIndex = 0 + } + for i := Length - 1; i > dirIndex; i-- { if filepath[i] == '.' { - // here to catch directories like .shared / .config - if i-1 == dirIndex { + // Handle dot-prefixed directories (.shared/.config) + if i > 0 && i-1 == dirIndex { break } return true } } return falseLet's verify the handling of various path formats:

45-45: Consider using a more descriptive comment.The term "over-engineering" is subjective and doesn't clearly explain why this approach is necessary. Consider rephrasing to better describe the technical limitations that necessitate this solution.
- // so we need to over-engineer a bit + // Windows API limitations require additional path analysis to determine symlink type
46-58: Several improvements needed for robustness and clarity.The function has the following areas for improvement:
- It assumes Windows-style path separators which could be problematic
- The backward traversal could be more efficient
- The function lacks documentation about its behavior
Consider this improved implementation:
+ // isFileSymlink determines if a path points to a file-type symlink rather than a directory-type symlink. + // Returns true if the path has a file extension (contains a dot after the last path separator), + // except for dot-prefixed directories (e.g., .config, .shared). isFileSymlink := func(filepath string) bool { - Length, dirIndex := len(filepath)-1, strings.LastIndex(filepath, "\\") - for i := Length; i > dirIndex; i-- { - if filepath[i] == '.' { - // here to catch directories like .shared / .config - if i-1 == dirIndex { - break - } - return true - } - } - return false + dirIndex := strings.LastIndex(filepath, string(os.PathSeparator)) + if dirIndex == -1 { + dirIndex = 0 + } + lastDotIndex := strings.LastIndex(filepath[dirIndex:], ".") + if lastDotIndex == -1 { + return false + } + // Handle dot-prefixed directories (e.g., .config, .shared) + return lastDotIndex != 0 }This improved version:
- Uses
os.PathSeparatorfor cross-platform compatibility- Uses
strings.LastIndexfor more efficient searching- Adds documentation explaining the function's purpose
- Handles edge cases more explicitly
Now symlink directories starting with . wont break anything
