8e6230ddd9 Change the multilog code to toggle between async and sync writes for all
log types.  This means the threaded_syslog type is no longer valid.  A new
fxn multilog_async is available to toggle between the two modes.  If an
app is compiled without pthreads and tries to use async logging, no logging
will occur while async is enabled.

dmeventd has been modified to use the new code

I'm not positive I like the way the async_logger code calls the log fxn,
but it works for now.  Suggestions for other ways to do it would be helpful

9e0419057c Exit after last unregister_for_event() 2005-05-20 13:53:26 +00:00

bca1803fea o Changed the multilog API a bit (I warned you)
- multilog_add_type, multilog_del_type, multilog_custom, and
     multilog_init_verbose all have different arguments.
   - Primary change is that caller only passes in config info, and the
     lib keeps track of state internally.  No more exporting of
     'struct log_data'.
   - Custom callers now only get the custom data pointer passed into their
     log fxn (that is set with multilog_custom)
   - Added basic README that describes libmultilog
2005-05-09 18:44:35 +00:00

cd4355d8f4 o stick multilog into the dm-event lib and dmeventd code again
o more tweaks to libmultilog calls - the api isn't set in stone yet, so
   don't get too comfortable.
 o not sure the dmeventd in device-mapper/dmeventd works - i've been using
   the one in lib/event/
 o currently both daemons are set to log only to syslog

Heinz Mauelshagen
d54da54d67 o checking in instrumented code for AJ to follow up on comms and logging
o changed

  int dm_get_next_registered_device(char **dso_name, char **device,
                                    enum event_type *events);

  to

  int dm_get_registered_device(char **dso_name, char **device,
                               enum event_type *events, int next)

  so that the daemon is able to retrive the next one of the list without
  running into locking issues.

o changed dmevent.c to use dm_get_registered_device()

o couldn't test this yet because of the comms issues
  (daemon exits in do_process_request())
