Spell that out in the comments. Also add GCC_FMT_ATTR() to qtest_hmp() etc. so that the compiler can flag incorrect use. We have some cleanup work to do before we can do the same for qtest_qmp() etc. This would get us the same better-than-nothing checking we already have for qobject_from_jsonf(): common incorrect uses of supported conversion specifications will be flagged (e.g. passing a double for %d), but use of unsupported ones won't.

Wrong. Its rationale for letting it fail is that all remaining users cope fine with failure. Well, they're just fine with aborting, too; it's what they do on failure. Simply reverting the broken commit would bring back the unfortunate asymmetry between qobject_from_jsonf() and qobject_from_jsonv(): one aborts, the other returns null. So also rename it to qobject_from_jsonf_nofail().

rsp = qmp(cmd); g_free(cmd); you're responsible for escaping the interpolated values for JSON. Not done here, and therefore works only for sufficiently nice @uri. For instance, if @uri contained a single "'", qobject_from_vjsonf_nofail() would abort. A sufficiently nasty @uri could even inject unwanted members into the arguments object. Leaving interpolation into JSON to qmp() is more robust: rsp = qmp("{ 'execute': 'migrate', 'arguments': { 'uri': %s } }", uri); It's also more concise. Clean up the simple cases where we interpolate exactly a JSON value. Bonus: gets rid of non-literal format strings.

Clean them up: * Have qtest_qmp_device_add() take its extra device properties as arguments for for qdict_from_jsonf_nofail() instead of a string containing JSON members. * Drop qpci_plug_device_test(), use qtest_qmp_device_add() directly. * Change usb_test_hotplug() parameter @port to string, to avoid interpolation. Interpolate @hcd_id separately. Bonus: gets rid of a non-literal format string. A step towards compile-time format string checking without triggering -Wformat-nonliteral.

Falls apart if @command contain '%'. Two ways to disarm this trap: suppress interpretation of '%' by passing @command as argument to format string "%s", or fix it by having wait_command() take the variable arguments to go with @command. Do the latter. This is another step towards compile-time format string checking without triggering -Wformat-nonliteral.
