2012-03-27qapi: fix double free in qmp_output_visitor_cleanup()Laszlo Ersek
Stack entries in QmpOutputVisitor are navigation links (weak references), except the bottom (ie. least recently added) entry, which owns the root QObject [1]. Make qmp_output_visitor_cleanup() drop the stack entries, then release the QObject tree by the root. Attempting to serialize an invalid enum inside a dictionary is an example for triggering the double free.

2012-02-21qapi: allow sharing enum implementation across visitorsPaolo Bonzini
Most visitors will use the same code for enum parsing. Move it to the core. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2011-11-17qapi: Check for negative enum valuesLuiz Capitulino
We don't currently check for negative enum values in qmp_output_type_enum(), this will very likely generate a segfault when triggered. However, it _seems_ that no code in tree can trigger this today.

2011-10-04qapi: modify visitor code generation for list iterationMichael Roth
Modify logic such that we never assign values to the list head argument to progress through the list on subsequent iterations, instead rely only on having our return value passed back in as an argument on the next call. Also update QMP I/O visitors and test cases accordingly, and add a missing test case for QmpOutputVisitor.

2011-07-21qapi: add QMP output visitorMichael Roth
Type of Visiter class that serves as the inverse of the input visitor: it takes a series of native C types and uses their values to construct a corresponding QObject. The command marshaling/dispatcher functions will use this to convert the output of QMP functions into a QObject that can be sent over the wire.
