Thomas Huth	fe823b6f87	io/channel-command: Do not kill the child process after closing the pipe We are currently facing some migration failure on s390x when running certain avocado-vt tests, e.g. when running the test type_specific.io-github-autotest-qemu.migrate.with_reboot.exec.gzip_exec. This test is using 'migrate -d "exec:nc localhost 5200"' for the migration. The problem is detected at the receiving side, where the migration stream apparently ends too early. However, the cause for the problem is at the sending side: After writing the migration stream into the pipe to netcat, the source QEMU calls qio_channel_command_close() which closes the pipe and immediately (!) kills the child process afterwards (via the function qio_channel_command_abort()). So if the sending netcat did not read the final bytes from the pipe yet, or if it did not manage to send out all its buffers yet, it is killed before the whole migration stream is passed to the destination side. QEMU can not know how much time is required by the child process to send over all migration data, so we should not kill it, neither directly nor after a delay. Let's simply wait for the child process to exit gracefully instead (this was also the behaviour of pclose() that was used in "exec:" migration before the QIOChannel rework).

Markus Armbruster	da34e65cb4	include/qemu/osdep.h: Don't include qapi/error.h Commit `57cb38b` included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little. More work is needed for that one.

Daniel P. Berrange	e155494cf0	io: some fixes to handling of /dev/null when running commands The /dev/null file handle was leaked in a couple of places. There is also the possibility that both readfd and writefd point to the same /dev/null file handle, so care must be taken not to close the same file handle twice.

Daniel P. Berrange	0c0a55b229	io: increment counter when killing off subcommand When killing the subcommand, it is intended to first send SIGTERM, then SIGKILL and only report an error if it still doesn't die after SIGKILL. The 'step' counter was not being incremented though, so the code never got past the SIGTERM stage. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>	11 years ago
