Adding a bit of notes after the research I did with Claude, in case this is still relevant (wasn't able to test locally). In It seems that the problem with double slashes in path only happened/happens when reading a directory of partitioned files, not when reading a specific file directly. Copilot suggests that the issue is in Arrow's dataset discovery code (in `cpp/src/arrow/dataset/discovery.cc`) and that the paths should be normalized before the `RemoveAncestor()` comparison in: https://github.com/apache/arrow/blob/118892700b95fdfa9a6b3e482a6e5399563f5d75/cpp/src/arrow/dataset/discovery.cc#L195-L196 For example with adding: ```cpp ARROW_ASSIGN_OR_RAISE(auto normalized_base_dir, filesystem->NormalizePath(selector.base_dir)); ARROW_ASSIGN_OR_RAISE(auto normalized_path, filesystem->NormalizePath(info.path())); ``` -- This is an automated message from the Apache Git Service.
