* src/lxc/lxc.conf: new configuration file, there is currently one
tunable "log_with_libvirtd" that controls whether an lxc controller will
log only to the container log file, or whether it will honor libvirtd's
log output configuration. This provides a way to have libvirtd and its
children log to a single file. The default is to log to the container
log file.
* src/Makefile.am libvirt.spec.in: add the new file
* src/lxc/lxc_conf.[ch] src/lxc/lxc_driver.c: read the new log value
from the configuration file and pass the log informations when
starting up a container.
* src/lxc/lxc_driver.c src/lxc/lxc_controller.c: before launching the
lxc controller, have the lxc driver query the log settings and setup
envp[]. This provides the advantage of honoring the actual log
configuration instead of only what had been set in the environment.
The lxc controller now simply has to call virLogSetFromEnv().
When configuring logging settings, keep more information about the
output destination. Add accessors to retrieve the filter and output
settings in the original string form; this to be used to set up
environment for a child process that also logs.
* src/util/logging.[ch]: add virLogGetFilters and virLogGetOutputs
accessors and modify the internals (including virLogDefineOutput())
to save the data needed for the accessors
* src/util/util.[ch]: Add virFileAbsPath() function to ensure an
absolute path for a potentially realtive path.
* src/libvirt_private.syms: add it in libvirt private symbols
* src/logging.c src/logging.h src/libvirt_private.syms:
define new functions virLogSetFromEnv and virLogParseDefaultPriority
* qemud/qemud.c src/libvirt.c tests/eventtest.c: cleanup to use the
unified functions
* qemud/qemud.c src/logging.[ch]: Similar as for general libvirt, don't
convert high priority levels to debug level. Ignore LIBVIRT_LOG_FILTERS
and LIBVIRT_LOG_OUTPUTS when they're set to the empty string, otherwise
they can override a valid setting from the config file. Send all
settings through the parser functions for validation, so that the
existence of a bad setting doesn't nullify a good setting that should
have applied -- particularly the default output. Keep the order of
precedence consistent for all variables between the environment and
the config file. Warn when an invalid log level, filter, or output
is ignored.
* src/libvirt_private.syms: export internally a few convenience functions
* src/libvirt.c src/logging.c: Don't convert high priority levels to the
debug level. Don't parse LIBVIRT_LOG_FILTERS and LIBVIRT_LOG_OUTPUTS
when they're set to the empty string. Warn when the user specifies an
invalid value (empty string remains a noop).
* po/POTFILES.in: src/logging.c now include translatable strings
