Bug 26125 - Clang format creates unwanted temporary files when batching processing on windows # Summary A file mapping object prevents the temp file from being deleted. This is a 100% repro on Windows. # Details When formatting a file in place, the original file is mapped into memory for reading. Later when trying to overwrite the changed file, kernel!ReplaceFile() renames the original file to <filename>~RFxxxx.TMP, creates a new file with <filename>, copies formatted content to it, and finally deletes <filename>~RFxxxx.TMP. Because there is still a open file mapping section to the original file (now with new file name <filename>~RFxxxx.TMP), delete fails with 0xc0000121 - STATUS_CANNOT_DELETE, leaving the temp file untouched after the clang-format operation. # Fix Releasing the file mapping object early allows deletefile to proceed
