/*---------------------------------------------------------------------------
Test program used to test the DMAPI function dm_get_allocinfo(). The
command line is:
dump_allocinfo [-D] [-n nelem] [-o offp] [-s sid] pathname
where pathname is the name of a file, 'offp' is a byte offset from the
beginning of the file where you want to start dumping, and 'nelem' allows
you to specify how many extent structures to use in each dm_get_allocinfo
call.
The code checks the returned extents as much as possible for errors.
It detects bad ex_type values, verifies that there is always a trailing
hole at the end of the file, that the ex_offset of each extent matches the
ex_offset+ex_length of the previous extent, and that ex_offset+ex_length
is always an even multiple of 512. It verifies that all ex_offset values
after the first fall on a 512-byte boundary. It verifies that the '*offp'
value returned by dm_get_allocinfo() is 0 at the end of the file, and
equals ex_offset+ex_length of the last extent if not at the end of the file.
Any error is reported to stderr, and the program then terminates with a
non-zero exit status.
The program produces output similar to xfs_bmap in order to make comparison
easier. Here is some sample output.
f1: offset 1
rc 0, nelemp 17
0: [0..127]: resv [1..511]
Line 1 gives the name of the file and the byte offset within the file where
the dump started. Line 2 appears once for each dm_get_allocinfo() call,
giving the return value (rc) and the number of extents which were returned.
Line 3 is repeated once for each extent. The first field "0:" is the extent
number. The second field "[0..127]:" give the starting and ending block for
the extent in 512-byte units. The third field is either "resv" to indicate
allocated space or "hole" if the extent is a hole. The fourth field
"[1..511]" only appears if the dump did not start with byte zero of the
first block. In that case, the first number shows the actual byte offset
within the block (1 in this case). The second number should always be
511 since we always dump to the end of a block.
Possible tests
--------------
Run the test scripts "test_allocinfo_1" and "test_allocinfo_2".
(The former compares dump_allocinfo output with xfs_bmap output. The latter
compares various dump_allocinfo outputs, from trials with many different
buffer sizes).
Produce a file with holes, and perform the following tests using just one
extent (-e 1).
Dump extents from beginning of the file.
Dump from byte 1 of the file.
Dump from the last byte of the first extent.
Dump from the first byte of the second extent.
Dump from the middle of the second extent.
Dump the first byte of the last extent.
Dump the last byte of the last extent.
Dump the first byte after the last extent.
Dump starting at an offset way past the end of the file.
Produce a fragmented file with many adjacent DM_EXTENT_RES extents.
Repeat the above tests.
Produce a GRIO file with holes.
Repeat the above tests.
