172c87f7ca Never try to test character past given buffer 
In case units[0] would be already '\0', do not check units[1].

52f2f3eae4 Add free_orphan_vg 
Move commod code to destroy orphan VG into free_orphan_vg() function.
Use orphan vgmem for creation of PV lists.
Remove some free_pv_fid() calls (FIXME: check all of them)
FIXME: Check whether we could merge release_vg back again for all VGs.

72b50d7fd2 give standard error message if lstat fails unexpectedly 2012-02-12 20:17:12 +00:00
Petr Rockai
6e41729eb8 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.

8e5f7cf3dc Move lvmcache data structures behind an API (making the structures private to 
lvmcache.c). No functional change.

b93c1332d1 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.

94f88a4f14 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).

9278655de1 Some fixmes

462835faa0 Switch to return void 
List delete cannot fail, so there is no reason to test for error.

33dea28e23 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.

d75c5f06f0 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().

84fd8ea4bd Move done jump lower 
Since before 'goto done' is bufused zeroed, it would otherwise write 1
byte in front of buffer.

b63b775143 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.

1a39fa0073 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.

02aeb23f1f Use dm_list_iterate_items_safe

5dfd775384 Ensure strncpy() function always ends with '\0'

pass buffer size smaller by 1 byte.

struct stat 'buf'.

42b5c54092 Add synchornization point in mirror log init.

it's activated for the second time.

ab852ffe66 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.

15fd61e492 Fix data% reporting 
For reading % of mapped size of thin volume use as origin for
