json: Report first rather than last parse error
Quiz time! When a parser reports multiple errors, but the user gets to see just one, which one is (on average) the least useful one? Yes, you're right, it's the last one! You're clearly familiar with compilers. Which one does QEMU report? Right again, the last one! You're clearly familiar with QEMU. Reproducer: feeding {"abc\xC2ijk": 1}\n to QMP produces {"error": {"class": "GenericError", "desc": "JSON parse error, key is not a string in object"}} Report the first error instead. The reproducer now produces {"error": {"class": "GenericError", "desc": "JSON parse error, invalid UTF-8 sequence in string"}} Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Message-Id: <20180823164025.12553-24-armbru@redhat.com>
