qmp-shell: fix nested json regression
Commit fcfab7541 ("qmp-shell: learn to send commands with quoted
arguments") introduces the usage of Python 'shlex' to handle quoted
arguments, but it accidentally broke generation of nested JSON
structs.
shlex drops quotes, which breaks parsing of the nested struct.
cmd='blockdev-create job-id="job0 foo" options={"driver":"qcow2","size":16384,"file":{"driver":"file","filename":"foo.qcow2"}}'
shlex.split(cmd)
['blockdev-create',
'job-id=job0 foo',
'options={driver:qcow2,size:16384,file:{driver:file,filename:foo.qcow2}}']
Replace with a regexp to split while respecting quoted strings and preserving quotes:
re.findall(r'''(?:[^\s"']|"(?:\\.|[^"])*"|'(?:\\.|[^'])*')+''', cmd)
['blockdev-create',
'job-id="job0 foo"',
'options={"driver":"qcow2","size":16384,"file":{"driver":"file","filename":"foo.qcow2"}}']
