      qtest: make QEMU our direct child process · cef60c92
      由 Stefan Hajnoczi 提交于 
      qtest_init() cannot use exec*p() to launch QEMU since the exec*p()
functions take an argument array while qtest_init() takes char
*extra_args.  Therefore we execute /bin/sh -c <command-line> and let the
shell parse the argument string.

This left /bin/sh as our child process and our child's child was QEMU.
We still want QEMU's pid so the -pidfile option was used to let QEMU
report its pid.

The pidfile needs to be unlinked when the test case exits or fails.  In
other words, the pidfile creates a new problem for us!

Simplify all this using the shell 'exec' command.  It allows us to
replace the /bin/sh process with QEMU.  Then we no longer need to use
-pidfile because we already know our fork child's pid.

Note: Yes, it seems silly to exec /bin/sh when we could just exec QEMU
directly.  But remember qtest_init() takes a single char *extra_args
command-line fragment instead of a real argv[] array, so we need
/bin/sh's argument parsing behavior.

      qtest: Use -display none by default · 2ad645d2
      由 Andreas Färber 提交于 
      This avoids each test needing to add it to suppress windows popping up.

[Commit 7ceeedd0 ("blockdev-test: add
test case for drive_add duplicate IDs") and commit
43cd2098 ("qdev-monitor-test: add
device_add leak test cases") added qtest tests without specifying
-display none.

As a result, "make check" now tries to use graphics (GTK or SDL).  Since
graphics are not used by the test and inappropriate for headless "make
check" runs, add the missing -display none.

This fixes "make check" in the QEMU buildbot.

      libqtest: Wait for the right child PID after killing QEMU · 6bf00766
      由 Eduardo Habkost 提交于 
      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).

      qtest: implement QTEST_STOP · e0fea6b1
      由 Paolo Bonzini 提交于 
      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.

      qtest: fix infinite loop when QEMU aborts abruptly · 039380a8
      由 Anthony Liguori 提交于 
      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.
