756c6f8560 Fix clvmd if compiled with gulm support. (2.02.26) 2007-07-24 15:35:11 +00:00

6fa6ce35da libdevmapper, dmeventd: be paranoid about detecting write failure
* dmeventd/dmeventd.c (_set_oom_adj): When writing to /proc/self/oom_adj,
detect failure even if it's hidden behind ferror.  [Using dm_fclose's
extra ferror test here is probably not needed, since the amount written
is nowhere near BUFSIZ, but use it regardless, for consistency. ]
* lib/fs/libdevmapper.c (do_suspend): Detect fclose failure when
writing to suspend.

1ec0d47f10 Use gcc's printf attribute wherever possible.
* daemons/clvmd/clvmd.h (debuglog): Add __attribute__((printf)).
* lib/config/config.c (_line_append): Likewise.
* lib/misc/lvm-string.h (emit_to_buffer): Likewise.

853460b20d 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.

7bc04fbad3 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  This means the threaded_syslog type is no longer valid.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

88f9534685 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

b355dd7b23 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.

48a186f172 o libmultilog needs introducing of list locking in order to stand
multilog_add_type()/multilog_del_type cycles correctly.
o fixed segfault in multilog_add_type()
o fixed test-multilog.c
o cleaned up libmultilog (list macros, indentation, braces, comments)

39dc7ec2ab - 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

2fedabd3b9 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

dbf2888d43 dmeventd was looking for dsos with libdmeventd<name>.so
The Makefile turned noop.c into    libdmeventnoop.so
The Makefile now turns noop.c into libdmeventdnoop.so

da36c286a6 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())
