Hi all,
We already have query-command-line-options to query details of command-line
options. As we discussed in the list, we also need full introspection of QMP
(command). The qmp-events also need to be dumped, we can define events in
qai-schema.json. We can also dump QMP errors in future if it's needed.
Command name: query-qmp-schema
Return: returns the contents of qapi-schema.json in json format.
Solution to query json content from C code:
qapi-schema.json is processed by qapi python scripts to generate C
files, I found the content is good enough for Libvirt to know the
QMP command schema. We can change qapi scripts to generate a talbe/list
to record the raw string, then we can return the raw string in
qmp_query_qmp_schema().
By default, return the complete schema in one go.
And support to query of unknown type in new command.
-> { "execute": "query-qmp-schema" "arguments": { "command": "query-status" }}
<- { "return" : "data": { "command': "query-status", "returns": "StatusInfo"
}}
-> { "execute": "query-qmp-schema" "arguments": { "type": "StatusInfo" }}
<- { "return" : "data": { "type": "StatusInfo", "data": {"running": "bool",
"singlestep": "bool", "status": "RunState"} }
-> { "execute": "query-qmp-schema" "arguments": { "event": "RX-FILTER-CHANGE"
}}
Welcome your comments, thanks!
