When a 0 sized block group item is found, set_extent_bits() will not
really set any bits.
While set_state_private() still inserts allocated block group cache into
block group extent_io_tree.
So at close_ctree() time, we won't free the private block group cache
stored since we can't find any bit set for the 0 sized block group.
To fix it, at btrfs_read_block_groups() we skip any 0 sized block group,
so such leak won't happen.

I was shocked to discover that 'btrfs receive --dump' doesn't print a
space after long filenames, so it runs together into the metadata; for
example:
truncate ./20-00-03/this-name-is-32-characters-longsize=0
This is a trivial patch to add a single space unconditionally, so the
result is the following:
truncate ./20-00-03/this-name-is-32-characters-long size=0
I suppose this is technically a breaking change, but it seems unlikely
to me that anyone would depend on the existing behavior given how
unfriendly it is.

[ enhance tests to take extra options and use for -e ]
Signed-off-by: David Sterba <dsterba@suse.com>
The old check here tried to ensure that empty streams are not considered valid.
The old check however, will always fail when only one run through the while(1)
loop is needed and honor_end_cmd is set. So this:
btrfs send /some/subvol | btrfs receive -e /some/
will consistently fail because -e causes honor_cmd_to be set and
btrfs_read_and_process_send_stream() to correctly return 1. So the command will
be successful but btrfs receive will error out because the send - receive
concluded in one run through the while(1) loop.
If we want to exclude empty streams we need a way to tell the difference between
btrfs_read_and_process_send_stream() returning 1 because read_buf() did not
detect any data and read_and_process_cmd() returning 1 because honor_end_cmd was
set. Without introducing too many changes the best way to me seems to have
btrfs_read_and_process_send_stream() return -ENODATA in the first case. The rest
stays the same. We can then check for -ENODATA in do_receive() and report a
proper error in this case. This should also be backwards compatible to previous
versions of btrfs receive. They will fail on empty streams because a negative
value is returned. The only thing that they will lack is a nice error message.

The easiest way to reproduce the error is to try to build
btrfs-progs with
$ make LDFLAGS=-Wl,--no-undefined
btrfs-list.o: In function `lookup_ino_path':
btrfs-list.c:(.text+0x7d2): undefined reference to `__error'
Noticed by Denis Descheneaux when snapper tool
stopped working after upgrade to btrfs-progs-4.10.
As soname didn't change in 4.9 -> 4.10 release
I assume it's just an object file omission
in library depends and not the API/ABI change
of the library error printing.

In check_extent_data_item(), after checking extent item of one data
extent, we search inlined data backref, then EXTENT_DATA_REF_KEY.
But we didn't search SHARED_DATA_REF, so if the backref is
SHARED_DATA_REF, then we will raise a false alert about backref lost.
Fix by also checking SHARED_DATA_REF_KEY in check_extent_data_item().
