7bfd1238ce Fixing some makesfiles, so that the correct things link against pthreads. 
Also changed dmevent so that in no longer links against pthreads, and
dynamically loads libdmevent.so.  Everything seems to work just fine like this.

5469414bf8 Timeout event implementation: 
The daemon side of this is mostly the same as the patch I sent out.  To select
a timeout period different than the default and to get the timeout period,
I added two library calls, dm_set_event_timeout() and dm_get_event_timeout().
If people are against them, the other option is to tack extra arguments onto
dm_regiser_for_event() and dm_get_registered_device().  I also added a
-t option to dmevent, so people can try out timeouts.

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  This means the threaded_syslog type is no longer valid.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

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

cbac299f5b fixed dmevent so that it doesn't do a double free when you run 
# dmevent -l

Also, changed the behaviour of dm_get_registered_device(), so that it doesn't
change the pointer you passed in without freeing the memory on a non-next call,
and doesn't free your pointer without setting it to NULL on a failed next call.

40773cd620 o libmultilog needs introducing of list locking in order to stand

o fixed segfault in multilog_add_type()
o fixed test-multilog.c
o cleaned up libmultilog (list macros, indentation, braces, comments)

1862e88ffa - make noop use multilog 
- add event_nr to thread_status struct and set appropriately so that the
  thread actually waits for an event
- essentially make error_detected return true.  Let the DSOs determine
  how to interpret the status info
 2005-05-04 01:57:31 +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

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,

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

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