-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 What are your thoughts on using Extended Attributes for items such as: * Dos Attributes (like samba's "store dos attributes = yes") * File Creation Times (like samba's proposed user.crtime) * An option for alternate storage of NT ACLs (like samba's "vfs object = acl-xattr")
Are Extended Attributes acceptable? Or should they never touch the wine source? Where would the portability functions for Extended Attributes on Linux, Mac OS X, FreeBSD and Solaris belong? I would think in libport. Attached is a patch to add extended attribute portability functions for fgetxattr, fsetxattr and fremovexattr to libport. Please give me any comments on this patch, and the idea of using extended attributes. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAksAm/4ACgkQTHDAI68NsumFzwCbBDcRbB8kFXroLeskA+hzgswu i0UAn3NHbau8AjSgtoruggBH3py+orcZ =tEvP -----END PGP SIGNATURE-----
