This adds a QAPI schema for the properties of the secret* objects. The 'loaded' property doesn't seem to make sense as an external interface: It is automatically set to true in ucc->complete, and explicitly setting it to true earlier just means that additional options will be silently ignored. In other words, the 'loaded' property is useless. Mark it as deprecated in the schema from the start.

#
|
|
# This command will get a property from a object model path and return the

|
|
#
|
|
# @path: The path within the object model. There are two forms of supported
|
|
# paths--absolute and partial paths.
|
|
#
|
|
# Absolute paths are derived from the root object and can follow child<>
|
|
# or link<> properties. Since they can follow link<> properties, they
|
|
# can be arbitrarily long. Absolute paths look like absolute filenames
|
|
# and are prefixed with a leading slash.
|
|
#
|
|
# Partial paths look like relative filenames. They do not begin
|
|
# with a prefix. The matching rules for partial paths are subtle but
|
|
# designed to make specifying objects easy. At each level of the
|
|
# composition tree, the partial path is matched as an absolute path.
|
|
# The first match is not returned. At least two matches are searched
|
|
# for. A successful result is only returned if only one match is
|
|
# found. If more than one match is found, a flag is return to
|
|
# indicate that the match was ambiguous.
|
|
#
|
|
# @property: The property name to read
|
|
#
|
|
# Returns: The property value. The type depends on the property
|
|
# type. child<> and link<> properties are returned as #str
|
|
# pathnames. All integer property types (u8, u16, etc) are
|
|
# returned as #int.
|
|
#
|

# Since: 1.2
