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!
