1b8724d866 Fix for gcc compilation warnings 
and put _XOPEN_SOURCE so pthread_mutexattr is properly defined.

49cd515cd2 Compile fix 
Reflecting change in dm_config_value  float r -> float f.

e68a6fbf20 Fix warnings and constness handling in lvmetad-core (adjusting the 
dm_config_find_node to give non-const node pointer, since that better reflects
the contract of that function).

04e647aa84 Adapt LVMetaD to use the new dm_config interfaces. 2011-08-30 15:44:01 +00:00

1d9c083fcc lvmetad: Edit the MISSING_PV flags only after making a "reply" copy of the 
metadata, which is then serialised and discarded. This fixes a couple of
outstanding TODO items about handling the MISSING flags correctly.

059ee25951 lvmetad: Check integrity of multiple metadata copies, i.e. ensure that seqno 
equality implies metadata equality. Signal error in response to any update
requests that try to overwrite metadata without providing a higher seqno.

9474992482 lvmetad: A couple of TODOs, and fix a few trivial memory leaks. 2011-07-25 15:33:04 +00:00

c2ca1a707a lvmetad: Obliterate vg_status by returning the same information from 
update_pv_status, saving a dozen lines of code and execution time of one
walkthrough of the PV list.

bc0a902434 lvmetad: Fix a possible infinite loop in vg_status. 2011-07-20 21:27:28 +00:00

fba6c62b84 lvmetad: Robustify update_pv_status and remove an useless lookup. 2011-07-20 21:26:18 +00:00
Petr Rockai
0cfb99d385 First stab at making lvmetad-core threadsafe. The current design should allow 
very reasonable amount of parallel access, although the hash tables may become
a point of contention under heavy loads. Nevertheless, there should be orders
of magnitude less contention on the hash table locks than we currently have on
block device scanning.

dcbf5a3b5d lvmetad: Avoid stale PV -> VG mappings on metadata update. 2011-07-20 18:45:32 +00:00

cd7bca83e1 Optimise PV -> VG lookups by using a UUID (hash) map. 2011-07-20 18:34:57 +00:00

652e0757c9 Free up allocated memory before exiting, in lvmetad. 2011-07-20 18:24:49 +00:00
Petr Rockai
42e23dbf6c Can't have a global memory pool in lvmetad (that would constitute an ongoing 
memory leak) => remove it (it's been unused anyway).

50ff3c076e Make lvmetad also report VGID in reply when adding a PV without MDAs (this 
obviously only works for VGs that already had at least some MDA discovered).
 2011-07-20 16:46:40 +00:00

c33d33bab7 Make lvmetad report the VG ID and status (complete, partial) in reply to pv_add 
requests.

3c238baf03 Work out some more details in metadata update in lvmetad. 2011-07-19 16:48:13 +00:00

9796bd4db6 More work on cache maintenance code in lvmetad: keep track of PV status. 2011-07-19 14:13:59 +00:00

252853560c Start filling in the core LVMetaD functionality and the corresponding 
testclient bits.

94bb67ab37 Add int/str lookup routines specific to the reply (in client) and request (in 
server) for nicer-looking code (thin wrapping around find_config_{int,str}).

aaca7f111f Also parse the config_tree on the client end (daemon-client.c). 2011-06-27 13:58:11 +00:00
Petr Rockai
55e300716f Parse the incoming config tree in daemon-server.c, providing the 
daemon-specific handler with a struct config_tree pointer to look things up in.

4fcbeed6ef Implement daemon_send_simple and use it in the testclient. 2011-06-27 13:15:49 +00:00
Petr Rockai
acf3616b3a Add a skeleton for lvmetad, a test client, and a temporary Makefile to build 
them. These are currently mostly for testing the daemon-common code. LVMetaD
functionality is expected to trickle in soon though.
