We traditionally mark optional members #optional in the doc comment. Before commit3313b61, this was entirely manual. Commit3313b61added some automation because its qapi2texi.py relied on #optional to determine whether a member is optional. This is no longer the case since the previous commit: the only thing qapi2texi.py still does with #optional is stripping it out. We still reject bogus qapi-schema.json and six places for qga/qapi-schema.json. Thus, you can't actually rely on #optional to see whether something is optional. Yet we still make people add it manually. That's just busy-work. Drop the code to check, fix up and strip out #optional, along with all instances of #optional. To keep it out, add code to reject it, to be dropped again once the dust settles. No change to generated documentation.

# @trace-event-get-state:
|
|
#
|
|
# Query the state of events.
|
|
#
|
|
# @name: Event name pattern (case-sensitive glob).
|
|
# @vcpu: The vCPU to query (any by default; since 2.7).
|
|
#
|
|
# Returns: a list of @TraceEventInfo for the matching events
|
|
#
|
|
# An event is returned if:
|
|
# - its name matches the @name pattern, and
|
|
# - if @vcpu is given, the event has the "vcpu" property.
|
|
#
|
|
# Therefore, if @vcpu is given, the operation will only match per-vCPU events,
|
|
# returning their state on the specified vCPU. Special case: if @name is an
|
|
# exact match, @vcpu is given and the event does not have the "vcpu" property,
|
|
# an error is returned.
