Previously:
- acl_get just returned for lpathconf returning EINVAL
- acl_get silently ignored all other lpathconf errors and
implied it is not a NFS4 acl
Now:
- not sure why the EINVAL silent return was done, but it seems
wrong. guess it could be the system not implementing a check
for nfs4. but in that case guess we still would like to get
the default and access ACL!? Thus, I removed the silent return.
- raise OSError for all lpathconf errors
Cosmetic: add a nfs4_acl boolean, so the code reads better.
... to implement same semantics as on linux (only store ACL
if it defines permissions other than those defined by the
traditional file permissions).
Looks like there is no call working with an fd on FreeBSD.
i.e. prefix the keys with the namespace, so it is ns.key like on
linux.
still only dealing with the "user" namespace, like before.
in the "system" namespaces there are ACLs (we deal with them via the acl
api, so no problem) and stuff from pnfsd (not sure what exactly).
this change is needed because FreeBSD's FUSE code expects the xattr
keys to be in that format.
it is also needed for cross-platform data exchange, so e.g. if one wants to:
- create archive on linux, extract on freebsd - with "user.xxx" xattrs.
- or vice versa.
archives made with older borg versions on freebsd will still extract correctly
on freebsd (not on linux though) even though they do not have the
namespace prefixes in the archived metadata (it will be interpreted in
same way as if they were prefixed by "user." as we do not support any
other namespace anyway).
they do not have "
this code used to live in borg.xattr and used ctypes
(and was the only ctypes-using code in borg).
the low level code now was converted to cython and
the platform code moved to platform package.
got rid of the code that tried to find the libc.
- move stuff to platform.base (should be platform independent according
to the docs).
- bump platform API version
- parseformat: import fqdn from platform instead of recomputing it
This is not yet fixing #3471, just a preparation for it.
