Re: [libvirt] [PATCH v2 01/10] virlog: Introduce virLog{Get, Set}DefaultOutput

These helpers will manage the log destination defaults (fetch/set). The reason for this is to stay consistent with the current daemon's behaviour with respect to /etc/libvirt/<daemon>.conf file, since both assignment of an empty string or not setting the log output variable at all trigger the daemon's decision on the default log destination which depends on whether the daemon runs daemonized or not. This patch also changes the logic of the selection of the default logging output compared to how it is done now. The main difference though is that we should only really care if we're running daemonized or not, disregarding the fact of (not) having a TTY completely (introduced by commit eba36a3878) as that should be of the libvirtd's parent concern (what FD it will pass to it). Before: if (godaemon || !hasTTY): if (journald): use journald if (godaemon): if (privileged): use SYSCONFIG/libvirtd.log else: use XDG_CONFIG_HOME/libvirtd.log else: use stderr After: if (godaemon): if (journald): use journald else: if (privileged): use SYSCONFIG/libvirtd.log else: use XDG_CONFIG_HOME/libvirtd.log else: use stderr Signed-off-by: Erik Skultety <eskultet(a)redhat.com&gt; --- src/libvirt_private.syms | 2 ++ src/util/virlog.c | 92 ++++++++++++++++++++++++++++++++++++++++++++++++ src/util/virlog.h | 2 ++ 3 files changed, 96 insertions(+)
