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>	2016-01-19 14:03:27 +00:00
Daniel P. Berrange	195e14d026	io: add QIOChannelCommand class ... Add a QIOChannel subclass that is capable of performing I/O to/from a separate process, via a pair of pipes. The command can be used for unidirectional or bi-directional I/O. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>	2015-12-18 12:18:31 +00:00
