From db29164103e53ae7c112086127e3d1c92b1d4d89 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Thu, 18 Mar 2021 16:55:18 +0100 Subject: qapi: Implement deprecated-input=reject for QMP command arguments This policy rejects deprecated input, and thus permits "testing the future". Implement it for QMP command arguments: reject commands with deprecated ones. Example: when QEMU is run with -compat deprecated-input=reject, then {"execute": "eject", "arguments": {"device": "cd"}} fails like this {"error": {"class": "GenericError", "desc": "Deprecated parameter 'device' disabled by policy"}} When the deprecated parameter is removed, the error will change to {"error": {"class": "GenericError", "desc": "Parameter 'device' is unexpected"}} Signed-off-by: Markus Armbruster Reviewed-by: Eric Blake Message-Id: <20210318155519.1224118-11-armbru@redhat.com> --- tests/unit/test-qmp-cmds.c | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) (limited to 'tests') diff --git a/tests/unit/test-qmp-cmds.c b/tests/unit/test-qmp-cmds.c index cba9821..266db07 100644 --- a/tests/unit/test-qmp-cmds.c +++ b/tests/unit/test-qmp-cmds.c @@ -303,6 +303,29 @@ static void test_dispatch_cmd_deprecated(void) do_qmp_dispatch_error(false, ERROR_CLASS_COMMAND_NOT_FOUND, cmd); } +static void test_dispatch_cmd_arg_deprecated(void) +{ + const char *cmd = "{ 'execute': 'test-features0'," + " 'arguments': { 'fs1': { 'foo': 42 } } }"; + QDict *ret; + + memset(&compat_policy, 0, sizeof(compat_policy)); + + /* accept */ + ret = qobject_to(QDict, do_qmp_dispatch(false, cmd)); + assert(ret && qdict_size(ret) == 1); + qobject_unref(ret); + + compat_policy.has_deprecated_input = true; + compat_policy.deprecated_input = COMPAT_POLICY_INPUT_ACCEPT; + ret = qobject_to(QDict, do_qmp_dispatch(false, cmd)); + assert(ret && qdict_size(ret) == 1); + qobject_unref(ret); + + compat_policy.deprecated_input = COMPAT_POLICY_INPUT_REJECT; + do_qmp_dispatch_error(false, ERROR_CLASS_GENERIC_ERROR, cmd); +} + static void test_dispatch_cmd_ret_deprecated(void) { const char *cmd = "{ 'execute': 'test-features0' }"; @@ -403,6 +426,8 @@ int main(int argc, char **argv) test_dispatch_cmd_success_response); g_test_add_func("/qmp/dispatch_cmd_deprecated", test_dispatch_cmd_deprecated); + g_test_add_func("/qmp/dispatch_cmd_arg_deprecated", + test_dispatch_cmd_arg_deprecated); g_test_add_func("/qmp/dispatch_cmd_ret_deprecated", test_dispatch_cmd_ret_deprecated); g_test_add_func("/qmp/dealloc_types", test_dealloc_types); -- cgit v1.1
