This commit changes all QERR_ macros to contain a human message (ie. the desc string found in qerr_table[]) instead of a json dictionary in string format. Before this commit, error_set() and qerror_report() would receive a json dictionary in string format and build a qobject from it. Now, both function receive a human message instead and the qobject is not built anymore. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com>
