From d708cdbe8792a55f53e90c1c787e871d527e8d4b Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Mon, 4 May 2015 09:05:19 -0600 Subject: qapi: Unify type bypass and add tests For a few QMP commands, we are forced to pass an arbitrary type without tracking it properly in QAPI. Among the existing clients, this unnamed type was spelled 'dict', 'visitor', and '**'; this patch standardizes on '**', matching the documentation changes earlier in the series. Meanwhile, for the 'gen' key, we have been ignoring the value, although the schema consistently used "'no'" ('success-response' was hard-coded to checking for 'no'). But now that we can support a literal "false" in the schema, we might as well use that rather than ignoring the value or special-casing a random string. Note that these are one-way switches (use of 'gen':true is not the same as omitting 'gen'). Also, the use of '**' requires 'gen':false, but the use of 'gen':false does not mandate the use of '**'. There is no difference to the generated code. Add some tests on what we'd like to guarantee, although it will take later patches to clean up test results and actually enforce the use of a bool parameter.
