class tacker.common.csar_utils.PreserveZipFilePermissions(file, mode='r', compression=0, allowZip64=True, compresslevel=None, *, strict_timestamps=True)

Bases: zipfile.ZipFile

Patched _extract_member function of zipFile.

zipfile.ZipFile.extractall function internally calls _extract_member function. Here _extract_member function is patched to retain the file permissions using member.external_attr >> 16.

Note: First 16 bits of external_attr store permission details.
