RE: RFR 8213031: (zipfs) Add support for POSIX file permissions

Hi Alan,

I will try to get time next week to reply to you on this. Part of the issue with your current approach is that it breaks PosixFileAttribtues. There are also issues trying to force the API to optionally support a subset of POSIX attributes on some zip entries and not on others. So several issues that will need consideration.

Thanks in advance for your work. Well, I can see that we could also support users/groups with zip files, which is also implemented in InfoZIP. Or we might add a Sub-Interface like PosixPermissionAttributes/PosixPermissionAttributesView. However, in any case, we have to find a way to deal with the optionality of any POSIX attributes in zip files. So, let's see what you come up with 😊 /Christoph
