6c75243a06 Add #include <signal.h> to dmeventd.c, fixes compilation on NetBSD. 2008-07-09 13:26:07 +00:00

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.

ce3a68d817 Make clvmd-cman use a hash rather than an array for node updown info. 
This will allow it to cope with very large nodeids such as those

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.
