This is an automated email from the git hooks/post-receive script.
bengen pushed a commit to annotated tag upstream/1.29.48
in repository libguestfs.
commit 9f85477cbac1427b8d4d314c8b7de7f703821891
Author: Richard W.M. Jones <rjones at redhat.com>
Date: Tue Jun 23 18:21:50 2015 +0100
tests: Add tests using a captive daemon process.
This allows us to test the daemon running as a host process, allowing
us to meaningfully test it using valgrind.
This commit only adds a single test that check that the daemon starts
up, can be pinged, and exits.
