kou opened a new pull request, #48777:
URL: https://github.com/apache/arrow/pull/48777
### Rationale for this change
We can't remove a file if someone is still opening the file on Windows.
We use `Tempfile` for tests. It removes associated file when it's GC-ed. If
we still open the associated file, the GC process reports the following warning:
```text
warning: Exception in finalizer
#<Tempfile::FinalizerManager:0x000001fb3c15ac00 @open_files={},
@path="D:/a/_temp/batch20260107-2120-ddy0e0.arrow", @pid=2120, @unlinked=false>
```
### What changes are included in this PR?
Ensure removing temporary files.
### Are these changes tested?
Yes.
### Are there any user-facing changes?
Yes. Only for `gparquet_arrow_file_reader_close()`.
