7 years agobtrfs-progs: Fix disable backtrace assert error
Qu Wenruo [Thu, 19 Jan 2017 04:00:03 +0000 (12:00 +0800)]
btrfs-progs: Fix disable backtrace assert error

Due to commit 00e769d04c2c83029d6c71(btrfs-progs: Correct value printed
by assertions/BUG_ON/WARN_ON), which changed the assert_trace()
parameter, the condition passed to assert/WARN_ON/BUG_ON are logical
notted for backtrace enabled and disabled case.

Such behavior makes us easier to pass value wrong, and in fact it did
cause us to pass wrong condition for ASSERT().

Instead of passing different conditions for ASSERT/WARN_ON/BUG_ON()
manually, this patch will use ASSERT() to implement the resting
ASSERT/WARN_ON/BUG() for disable backtrace case, and use assert_trace()
to implement ASSERT() and BUG_ON(), to allow them to print correct
value.

Also, move WARN_ON() out of the ifdef branch, as it's completely the
same for both branches.

btrfs-progs: dev stats: add dev stats returncode option

Currently, `btrfs device stats` returns non-zero only when there was an
error getting the counter values.  This is fine for when it gets run by a
user directly, but is a serious pain when trying to use it in a script or
for monitoring since you need to parse the (not at all machine friendly)
output to check the counter values.

This patch adds an option ('-s') which causes `btrfs device stats`
to set bit 6 in the return code if any of the counters are non-zero.
This greatly simplifies checking from a script or monitoring software if
any errors have been recorded.  In the event that this switch is passed
and an error occurs reading the stats, the return code will have bit
0 set (so if there are errors reading counters, and the counters which
were read were non-zero, the return value will be 65).

tree 258 and 260, we can just skip it.

Notice even with this patch, we still may visit a shared node or leaf
multiple times. This happens when a inode metadata occupies multiple
leaves.

                 leaf_A     leaf_B
When checking inode item in leaf_A, assume inode[512] have file extents
in leaf_B, and leaf_B is shared. In the case, for inode[512], we must
visit leaf_B to have inode item checked. After finishing inode[512] check,
here we walk down tree root to leaf_B to check whether node or leaf
is shared, if some node or leaf is shared, we can just skip it and below
nodes or leaf's check.

I also fill a disk partition with linux source codes and create 3
snapshots in it. Before this patch, it averagely took 46s to finish one
btrfsck execution, with this patch, it averagely took 15s.

btrfs-progs: check: fix the return value bug of cmd_check()

The function cmd_check() is called by the main function of btrfs.c, its
return value will be returned by exit(). Resulting in the loss of
significant bits in some cases, for example this value is greater than
0377. If use a bool value "err" to store all of the return value, this
