This ticket has a small catch:
There are several namespaces. According to http://en.wikipedia.org/wiki/Xattr#Linux :
- user: can be set by anyone
- trusted: root only
- security: root only
- system: even root can’t do that, at least not in my vm
I’m writing a shutil.copyxattr() first which could simple get another argument for the namespaces that should be copied.
However what to do inside copy2()?
I’m tending to either:
1. copy only user.*
2. ignore errors in any namespace != user
Personally, I find the second approach rather non-deterministic.
So I’d suggest:
- copyxattr has an extra argument called namespaces with default being ['user'], so that in theory someone who wants to do something more sophisticated can do it.
- copy2 copies only user.* though because that’s what you usually want.
Please let me know what you think about it. |
