class ACL(__builtin__.object) |

Type which represents a POSIX ACL
Parameters:
Only one keword parameter should be provided:
- file="...", meaning create ACL representing
the access ACL of that file
- filedef="...", meaning create ACL representing
the default ACL of that directory
- fd=<int>, meaning create ACL representing
the access ACL of that file descriptor
- text="...", meaning create ACL from a
textual description
- acl=<ACL instance>, meaning create a copy
of an existing ACL instance
If no parameters are passed, create an empty ACL; this
makes sense only when your OS supports ACL modification
(i.e. it implements full POSIX.1e support)

Methods defined here:
- __getstate__(...)
- Dumps the ACL to an external format.
- __init__(...)
- x.__init__(...) initializes x; see x.__class__.__doc__ for signature
- __iter__(...)
- x.__iter__() <==> iter(x)
- __setstate__(...)
- Loads the ACL from an external format.
- __str__(...)
- x.__str__() <==> str(x)
- applyto(...)
- Apply the ACL to a file or filehandle.
Parameters:
- either a filename or a file-like object or an integer; this
represents the filesystem object on which to act
- optional flag representing the type of ACL to set, either
ACL_TYPE_ACCESS (default) or ACL_TYPE_DEFAULT
- delentry(...)
- Deletes an entry from the ACL.
Note: Only with level 2
Parameters:
- the Entry object which should be deleted; note that after
this function is called, that object is unusable any longer
and should be deleted
- next(...)
- x.next() -> the next value, or raise StopIteration
- valid(...)
- Test the ACL for validity.
This method tests the ACL to see if it is a valid ACL
in terms of the filesystem. More precisely, it checks:
A valid ACL contains exactly one entry with each of the ACL_USER_OBJ,
ACL_GROUP_OBJ, and ACL_OTHER tag types. Entries with ACL_USER and
ACL_GROUP tag types may appear zero or more times in an ACL. An ACL that
contains entries of ACL_USER or ACL_GROUP tag types must contain exactly
one entry of the ACL_MASK tag type. If an ACL contains no entries of
ACL_USER or ACL_GROUP tag types, the ACL_MASK entry is optional.
All user ID qualifiers must be unique among all entries of ACL_USER tag
type, and all group IDs must be unique among all entries of ACL_GROUP tag
type.
The method will return 1 for a valid ACL and 0 for an invalid one.
This has been chosen because the specification for acl_valid in POSIX.1e
documents only one possible value for errno in case of an invalid ACL,
so we can't differentiate between classes of errors. Other suggestions
are welcome.
Data and non-method functions defined here:
- __doc__ = 'Type which represents a POSIX ACL\n\nParameters:\n ...tion\n (i.e. it implements full POSIX.1e support)\n'
- str(object) -> string
Return a nice string representation of the object.
If the argument is a string, the return value is the same object.
- __new__ = <built-in method __new__ of type object>
- T.__new__(S, ...) -> a new object with type S, a subtype of T

class Entry(__builtin__.object) |
| |
Type which represents an entry in an ACL.
The type exists only if the OS has full support for POSIX.1e
Can be created either by:
e = posix1e.Entry(myACL) # this creates a new entry in the ACL
or by:
for entry in myACL:
print entry

Methods defined here:
- __init__(...)
- x.__init__(...) initializes x; see x.__class__.__doc__ for signature
- __str__(...)
- x.__str__() <==> str(x)
- copy(...)
- Copy an ACL entry.
This method sets all the parameters to those of another
entry, even one of another's ACL
Parameters:
- src, instance of type Entry
Data and non-method functions defined here:
- __doc__ = 'Type which represents an entry in an ACL.\n\nThe t...L\nor by:\n for entry in myACL:\n print entry\n'
- str(object) -> string
Return a nice string representation of the object.
If the argument is a string, the return value is the same object.
- __new__ = <built-in method __new__ of type object>
- T.__new__(S, ...) -> a new object with type S, a subtype of T
- parent = <attribute 'parent' of 'posix1e.Entry' objects>
- The parent ACL of this entry
- permset = <attribute 'permset' of 'posix1e.Entry' objects>
- The permission set of this ACL entry
- qualifier = <attribute 'qualifier' of 'posix1e.Entry' objects>
- The qualifier of the current entry
If the tag type is ACL_USER, this should be a user id.
If the tag type if ACL_GROUP, this should be a group id.
Else, it doesn't matter.
- tag_type = <attribute 'tag_type' of 'posix1e.Entry' objects>
- The tag type of the current entry
This is one of:
- ACL_UNDEFINED_TAG
- ACL_USER_OBJ
- ACL_USER
- ACL_GROUP_OBJ
- ACL_GROUP
- ACL_MASK
- ACL_OTHER

class Permset(__builtin__.object) |
