2015-12-04tests: Use proper functions types instead of void (*fn)Markus Armbruster
We have several function parameters declared as void (*fn). This is just a stupid way to write void *, and the only purpose writing it like that could serve is obscuring the sin of bypassing the type system without need. The original sin is commit 49ee359: its qtest_add_func() is a wrapper for g_test_add_func(). Fix the parameter type to match g_test_add_func()'s. This uncovers type errors in ide-test.c; fix them. Commit 7949c0e faithfully repeated the sin for qtest_add_data_func(). Fix it the same way, along with a harmless type error uncovered in vhost-user-test.c. Commit 063c23d repeated it for qtest_add_abrt_handler(). The screwy parameter gets assigned to GHook member func, so change its type to match. Requires wrapping kill_qemu() to keep the type checker happy.

2015-10-09libqtest: New hmp() & friendsMarkus Armbruster
New convenience function hmp() to facilitate use of human-monitor-command in tests. Use it to simplify its existing uses. To blend into existing libqtest code, also add qtest_hmpv() and qtest_hmp(). That, and the egregiously verbose GTK-Doc comment format make this patch look bigger than it is.

2015-05-22qtest: Add base64 encoded read/writeJohn Snow
For larger pieces of data that won't need to be debugged and viewing the hex nibbles is unlikely to be useful, we can encode data using base64 instead of encoding each byte as %02x, which leads to some space savings and faster reads/writes. For now, the default is left as hex nibbles in memwrite() and memread(). For the purposes of making qtest io easier to read and debug, some callers may want to specify using the old encoding format for small patches of data where the savings from base64 wouldn't be that profound. memwrite/memread use a data encoding that takes 2x the size of the original buffer, but base64 uses "only" (4/3)x, so for larger buffers we can save a decent amount of time and space.

2015-04-28libqtest: add qmp_asyncJohn Snow
Add qmp_async, which lets us send QMP commands asynchronously. This is useful when we want to send commands that will trigger event responses, but we don't know in what order to expect them. Sometimes the event responses may arrive even before the command confirmation will show up, so it is convenient to leave the responses in the stream.

This patch fixes compilation errors when building against glib <2.28.0 due to the missing g_get_monotonic_time() function. The compilation error in tests/libqos/virtio.c was introduced in commit 70556264a89a268efba1d7e8e341adcdd7881eb4 ("libqos: use microseconds instead of iterations for virtio timeout").

2014-03-13qtest: Fix crash if SIGABRT during qtest_init()Stefan Hajnoczi
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.

2013-02-18libqtest: Convert macros to functions and clean up documentationAndreas Färber
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.
