[New-bugs-announce] [issue15795] Zipfile.extractall does not preserve file permissions

[Alexey Boriskin]

New submission from Alexey Boriskin:

Zipfile._extract_member does not preserve file permissions while extracting it. As may be seen at link[1], raw open() is used and no os.chmod() applied after that, therefore any permission data stored in zipfile is dropped and file is created with default permission depending on current user's umask.
