Petr Rockai
14d7b7b4e9 Keep a global (per-format) orphan_vg and keep any and all orphan PVs linked to 
it. Avoids the need for FMT_INSTANCE_PV and enables further simplifications. No
functional change, internal refactor only.

395ee036d7 What's new: lvmcache. 2012-02-10 01:29:46 +00:00
Petr Rockai
1a28df6bb4 Move lvmcache data structures behind an API (making the structures private to 
lvmcache.c). No functional change.

e98b640d5d Move label_init up in code stack 
label_exit() is called destroy_toolcontext() and we are now
using standard dm_list function for destroy, we have to make sure
dm_list gets initialized properly.

70e3728446 Fix test for lv_snapshot_percent 
Do not check for PERCENT_MERGE_FAILED if the lv_snapshot_percent() failed.
(test for snap_percent would be testing uninitialized value).

7ce534f911 Switch to return void 
List delete cannot fail, so there is no reason to test for error.

f03f322f13 Use dm_snprintf and improve error handling 
Add standard error reporting with error logging.
Use plain alloc instead of zalloc for string buffer.
Use dm_snprintf with valid test for <0.

6bea32ccf2 Remove duplicate test 
Tested condition has been already evaluated before
For strlen() code has already excluded <ID_LEN.
For repairing, already tested (!argc && !repairing) before.

84facc4fa5 Replace snprintf with dm_snprintf 
snprintf testing for negative is replaced with dm_snprintf where this
test really works.
Add missing test for result of dm_snprintf().

cc525412f1 Keep page_size as signed number

962fd76f26 Move done jump lower 
Since before 'goto done' is bufused zeroed, it would otherwise write 1
byte in front of buffer.

6e40adde76 Add boundary test for number of mirror devs and logs 
As atoi may return negative value - test for both limits.
Test log_args for limits before calling alloca().
Code from dmeventd mirror plugin should probably share same code as
we have in mirrored.c.

fb6a209080 Set all parameters to 0 
Since the function dm_get_next_target() returns NULL as 'next' pointer
so it's not a 'real' error - set 0 to all parameters when NULL is
returned because of missing head.

i.e. one of use case::
do {
	next = dm_get_next_target(dmt, next, &start, &length,
				  &target_type, &params);
	size += length;
} while (next);

bb0862fbb4 Move close few lines 
Since the function dev_close() has code path, which really could close
file (for unlocked vg) and destroy dev handler, stay on safe side and move
the close few lines later, even our current use case shouldn't trigger
such scenario.

4443aa41cc Ensure strncpy() function always ends with '\0'

pass buffer size smaller by 1 byte.

24da0046d5 Set status for error path

when the function returns error.

it's activated for the second time.

02f6f4902f Disable partial activation for thin LVs and LVs with all missing segments 
Count number of error and existing areas and if there is no existing area
for the LV avoid its activation.

Always disable partial activatio for thin volumes.

For mirrors currently put in hack to let it pass with a special name
since current mirror code needs to activate such LV during some operations.
