Bug 550006 – sys-apps/portage: quickpkg does not preserve xattrs

• Product: Portage Development
• Status: RESOLVED FIXED

[Description Zac Medico 2015-05-21 03:35:41 UTC]

Since quicpkg uses python's tarfile module which does not support xattrs, we have a couple of options:

1) We can still use python's tarfile if we can use it to emulate the ways that GNU tar and/or bsdtar store xattrs.

2) We can use GNU tar and/or bsdtar. The --files-from option allows us to add files without the need to copy them to a temp directory first. Special quickpkg --include-config=n handling can be implemented by creating a tree of empty config files in a temporary directory, and using the GNU tar --transform option or bsdtar -s option to correct their path in the resulting tar file.

It appears that GNU tar represents xattrs as pax headers that python's tarfile module is capable of manipulating.
