efde37880b Fix dmeventd regression where mirror and snapshot monitoring libraries 
failed to link against liblvm2cmd.

Dmeventd DSOs *require* lvm2cmd to be linked in.

For the future:
1) AC_SUBST does not create Makefile variables, only @foo@-style substitutions
2) When using `test', whitespace around `=' is essential:
    test a=b is true, as is test a=a

062886df64 avoid link failure when configuring without --enable-cmdlib 
* configure.in (LVM2CMD_LIB): Define if --enable-cmdlib.
* dmeventd/mirror/Makefile.in (CLDFLAGS): Use $(LVM2CMD_LIB) rather
than hard-coding -llvm2cmd.
* dmeventd/snapshot/Makefile.in (CLDFLAGS): Likewise.

9154a74400 . remove_lock_wait.diff remove the definition of "struct lock_wait", 
which is not used since the switch away from async version saLck
. num_nodes should equal to member_list_entries, i.e.
joined_list_entires is 0 when a node leaves the group.

Thanks to Xinwei Hu for the patch.

1399b84b32 The attached patch is a try to make clvmd work correctly on openais stack. 
It does 2 things.

1. The cpg_deliver_callback make a compare between target_nodeid and our_nodeid.
It turns out openais set target_nodeid to 0 sometimes. for broadcasting ? I change the behavior so that lvm will process_remote also on target_nodeid == 0

2. The joined_list passed to cpg_confchg_callback doesn't include the already exist nodes in the group, which leads to an incomplete node_hash. I simply add all other nodes in member_list to node_hash also.

Thanks to Xinwei Hu for this patch.

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.

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.

main loop.

20f3408d96 Report detailed errors in cluster initialisation to syslog, and point the user 
at syslog if clvmd fails to intialise.

e9d86789db Can now build a gulm version of clvmd instead of a cman one. use 
./configure --with-clvmd=gulm

The default is still cman, and you can't have both - sorry.

d48f8bf5cc Make clvmd -V display the lvm version number too rather than just 
the protocol version (which is not that useful and doesn't change very often).

99d97754a6 Revert the fork back to where it was as it seems to confuse pthreads. 
Instead, the parent now waits for the daemon to signal that it has
completed successfully (or not) so it can return status to the user.

b9d437de2a Change some perror() calls to log_error() so they'll appear in 
syslog when we're a daemon.

11403f2019 Check the UUID length when readingthe output of the "lvs" command at startup. 
This way we should not get quite so confused by any debugging output
that may come our way.

e3ef54f99b Fork a little later in the startup sequence so that we can return 
an error code if the cluster infrastructure isn't there.

6533aa865a Keep client locks (VG locks usually) in their own hash table so 
we can actually have more then one of them per client.

953f4838dd Make the thread handling a little less cavalier. In particular, calling 
pthread_exit in a signal handler was a /really/ bad idea.

130b892d34 Don't use hold_lock for VG locks as that doesn't stop processes contending 
on the same node, only across the cluster.
