Merge from trunk revno: 2330
The apache2 mod_apparmor module was failing to log debugging messages
when the apache loglevel was set to debug or lower (i.e. traceN). This
patch fixes it by using ap_log_rerror() (for request specific messages,
with the request passed for context) and ap_log_error() (more general
messages outside of a request context).
Also, the APLOG_USE_MODULE macro is called, to mark the log messages
as belonging to the apparmor module, so that the apache 2.4 feature
of enabling debug logging for just the apparmor module will work,
with an apache configuration entry like:
LogLevel apparmor:debug
See
http://ci.apache.org/projects/httpd/trunk/doxygen/group__APACHE__CORE__LOG.html
for specific about the ap_log_*error() and APLOG_USE_MODULE functions
and macros, and
http://httpd.apache.org/docs/2.4/mod/core.html.en#loglevel
for the bits about module specific logging.
Patch history:
v1: initial version
v2: - revert to using ap_log_error with (the 2.4 specific)
ap_server_conf outside of a request specific context, as the
pool specific ap_log_perror messages weren't being reported.
- add compatibility workaround for apache 2.2
v3: keep commented out merge function's log call consistent with the
others
