* ctdb-logging: New option CTDB_LOGGING, remove CTDB_LOGFILE, CTDB_SYSLOGMartin Schwenke2014-10-2815-75/+177
| | | | | | | | | | | | Remove --logfile and --syslog daemon options and replace with --logging. Modularise and clean up logging initialisation code. The initialisation API includes an app_name argument that is currently unused - this will be used in extensions to the syslog backend.

* ctdb-logging: Replace logd code with a basic syslog(3) implementationMartin Schwenke2014-10-284-224/+10
| | | | | | | | | | | | | | It is much simpler for most cases to have a syslog backend that doesn't need a separate CTDB-specific logging daemon. This loses the lossy, non-blocking mode provided by logd. However, a corresponding feature with a completely different implemention (not requiring an extra daemon) will be re-added into the syslog backend. In an ideal world the new implementation would be added first but unfortunately that is hard to do because the logd code is hooked in at more than one place.

| | | | | | | | | | | | | Put declarations into ctdb_logging.h, factor out some common code, clean up #includes. Remove the check so see if the 1st character of the debug level is '-'. This is wrong, since it is trying to check for a negative numeric debug level (which is no longer supported) and would need to be handled in the else anyway.

| | | | | | | | | | | | | | Internally map them to DEBUG_ERR to limit code churn. This reduces the unwieldy number of debug levels used by CTDB. ALERT and CRIT aren't of much use as separate errors, since everything from ERR up should always be logged. In future just ERR can be used. This also improves compatibility with Samba's debug.c system priority mapping. Signed-off-by: Martin Schwenke <martin@meltin.net> Reviewed-by: Amitay Isaacs <amitay@gmail.com>

| | | | | | | | | | | | | | | | | | Remove local lib/util and lib/tdb-wrap. Update wscript, packaging and includes.h. The only potentially surprising thing here is a fake samba-util subsystem that just depends on samba-util-core. As explained in a comment: When a combined build is implemented, CTDB will wanted to build against samba-util rather than samba-util-core. Similarly, other Samba subsystems expect samba-util. So, for a standalone build, just define a fake samba-util subsystem that pulls in samba-util-core. Signed-off-by: Martin Schwenke <martin@meltin.net> Reviewed-by: Volker Lendecke <vl@samba.org>

| | | | | | | | | | | | | | | | | | | | | Samba's debug subsystem has changed a lot, so CTDB's logging needs to be rewritten to be compatible. The new debug.h/debug.c can't just be pulled in because it has some extra dependencies into Samba's lib/util. For now, to support the smallest possible patch, implement a minimal subset of Samba's debug.[ch] that just supports the DEBUG_CALLBACK logtype. Define a callback for each logging method. Check later to see if debug_extra (or similar) can somehow be implemented using debug classes. The timestamp on CTDB CLI tool and test program DEBUG() output goes away, so update the unit test code to cope.
