2013-04-17qtest: don't use system command to avoid double forkAnthony Liguori
Currently we waitpid on the child process we spawn off that does nothing more than system() another process. While this does not appear to be incorrect, it's wasteful and confusing so get rid of it.

2013-02-18qtest: Add MMIO supportAndreas Färber
Introduce [qtest_]{read,write}[bwlq]() libqtest functions and corresponding QTest protocol commands to replace local versions in libi2c-omap.c. Also convert m48t59-test's cmos_{read,write}_mmio() to {read,write}b().

2013-02-18libqtest: Introduce qtest_qmpv() and convert remaining macroAndreas Färber
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.

2013-02-01libqtest: Wait for the right child PID after killing QEMUEduardo Habkost
When running "make check" with gcov enabled, we get the following message: hw/tmp105.gcda:cannot open data file, assuming not executed The problem happens because: * tmp105-test exits before QEMU exits, because waitpid() at qtest_quit() fails; * waitpid() fails because there's another process already waiting for the QEMU process; * The process that is already waiting for QEMU is the child created by qtest_init() to run system(); * qtest_quit() is incorrectly waiting for the QEMU PID directly instead of the child created by qtest_init(). This fixes the problem by sending SIGTERM to QEMU, but waiting for the child process created by qtest_init() (that exits immediately after QEMU exits).

2012-10-05qtest: implement QTEST_STOPPaolo Bonzini
It is quite difficult to debug qtest test cases without extra wrapper scripts for QEMU or similar. This patch adds a simple environment variable-based trigger that sends a STOP signal to the QEMU instance under test, before attempting to connect to its QMP session. This will block execution of the testcase and give time to attach a debugger to the stopped QEMU process.

2012-06-27qtest: fix infinite loop when QEMU aborts abruptlyAnthony Liguori
From Markus: Makes "make check" hang: QTEST_QEMU_BINARY=x86_64-softmmu/qemu-system-x86_64 gtester -k --verbose -m=quick tests/crash-test tests/rtc-test TEST: tests/crash-test... (pid=972) qemu-system-x86_64: Device needs media, but drive is empty [Nothing happens, wait a while, then hit ^C] make: *** [check-qtest-x86_64] Interrupt This was due to the fact that we weren't checked for errors when reading from the QMP socket. This patch adds appropriate error checking. Reported-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
