2014-03-13qtest: Fix crash if SIGABRT during qtest_init()Stefan Hajnoczi1-3/+1
If an assertion fails during qtest_init() the SIGABRT handler is invoked. This is the correct behavior since we need to kill the QEMU process to avoid leaking it when the test dies. The global_qtest pointer used by the SIGABRT handler is currently only assigned after qtest_init() returns. This results in a segfault if an assertion failure occurs during qtest_init(). Move global_qtest assignment inside qtest_init(). Not pretty but let's face it - the signal handler depends on global state.

2014-03-13libqtest: Avoid inline varargs functionsPeter Maydell1-18/+2
Older versions of gcc (eg 4.6) can't handle varargs functions declared inline for anything other than completely trivial uses, and complain: tests/qom-test.c: In function 'qmp': tests/libqtest.h:359:60: sorry, unimplemented: function 'qmp' can never be inlined because it uses variable argument lists Avoid this problem by putting the functions into libqtest.c instead of using inline definitions in libqtest.h.

2013-11-07libqtest: add qmp(fmt, ...) -> QDict* functionStefan Hajnoczi1-0/+37
Add a qtest qmp() function that returns the response object. This allows test cases to verify the result or to check for error responses. It also allows waiting for QMP events.

2013-11-07libqtest: rename qmp() to qmp_discard_response()Stefan Hajnoczi1-10/+10
Existing qmp() callers do not expect a response object. In order to implement real QMP test cases it will be necessary to inspect the response object. Rename qmp() to qmp_discard_response(). Later patches will introduce a qmp() function that returns the response object and tests that use it.

2013-02-18libqtest: Introduce qtest_qmpv() and convert remaining macroAndreas Färber1-1/+19
In order to convert qmp() macro to an inline function, expose a qtest_qmpv() function, reused by qtest_qmp(). We can't apply GCC_FMT_ATTR() since fdc-test is using zero-length format strings, which would result in warnings treated as errors.

2013-02-18libqtest: Convert macros to functions and clean up documentationAndreas Färber1-50/+110
libqtest.h provides a number of shortcut macros to avoid tests feeding it the QTestState they operate on. Most of these can easily be turned into static inline functions, so let's do that for clarity. This avoids getting off-by-one error messages when passing wrong args. Some macros had a val argument but documented @value argument. Fix this. While touching things, enforce gtk-doc markup for return values and for referencing types.
