# Description of test files for tarlz:
# test.txt.tar.lz:   1 member (test.txt).
# t155.tar[.lz]:     directory + 3 links + file + EOA, all with 155 char names
# t155_fv?.tar[.lz]: like t155.tar but with 3 kinds of format violations
# t155_fv1.tar[.lz]: extra extended header before EOA blocks
# t155_fv2.tar[.lz]: first extended header followed by global header
# t155_fv3.tar[.lz]: consecutive extended headers in last member
# t155_fv[456].tar.lz: like t155_fv[123].tar.lz but violation alone in member
# tar_in_tlz1.tar.lz: 2 members (test.txt.tar test3.tar) 3 lzip members
# tar_in_tlz2.tar.lz: 2 members (test.txt.tar test3.tar) 5 lzip members
# ts_in_link.tar.lz: 4 symbolic links (link[1-4]) to / /dir/ dir/ dir(107/)
# test_bad1.txt.tar.lz: truncated at offset 6000 (of 7495)
# test_bad2.txt.tar.lz: byte at offset 6000 changed from 0x56 to 0x46
# test3.tar[.lz]:    3 members (foo bar baz) + 2 zeroed 512-byte blocks
# test3_dir.tar[.lz] like test3.tar but members /dir/foo /dir/bar /dir/baz
# test3_dot.tar.lz:  3 times 3 members ./foo ././bar ./././baz
#                    the 3 central members with filename in extended header
# test3_bad1.tar:    byte at offset  259 changed from 't' to '0' (magic)
# test3_bad2.tar:    byte at offset 1283 changed from 't' to '0' (magic)
# test3_bad3.tar:    byte at offset 2559 changed from 0x00 to 0x20 (padding)
# test3_bad4.tar:    byte at offset 1283 changed from 't' to '0' (magic)
#                    byte at offset 2307 changed from 't' to '0' (magic)
# test3_bad5.tar:    510 zeros + "LZ" prepended to test3.tar (bogus lz header)
# test3_bad1.tar.lz: byte at offset    2 changed from 'I' to 'i' (magic)
# test3_bad2.tar.lz: byte at offset   49 changed from 0x49 to 0x69 (mid stream)
# test3_bad3.tar.lz: byte at offset  176 changed from 0x7D to 0x6D (mid stream)
# test3_bad4.tar.lz: combined damage of test3_bad2.tar.lz and test3_bad3.tar.lz
# test3_bad5.tar.lz: [71-134] --> zeroed (first trailer + second header)
# test3_bad6.tar.lz: 510 zeros prepended to test3.tar.lz (header in two blocks)
# test3_eoa?.tar:    like test3_eoa?.tar.lz but uncompressed
# test3_eoa1.tar.lz: test3.tar.lz without EOA blocks
# test3_eoa2.tar.lz: test3.tar.lz with only one EOA block
# test3_eoa3.tar.lz: test3.tar.lz with one zeroed block between foo and bar
# test3_eoa4.tar.lz: test3.tar.lz ended by extended header without EOA blocks
# test3_eoa5.tar.lz: test3.tar.lz split extended bar member, without EOA blocks
# test3_em?.tar.lz:  test3.tar.lz with one empty lzip member at each position
# test3_em6.tar.lz:  test3.tar.lz preceded by four empty lzip members
# test3_gh?.tar:     test3.tar with global header at each position
# test3_gh?.tar.lz:  test3.tar.lz with global before bar split in 4 ways
# test3_gh5.tar.lz:  test3.tar.lz with global in lzip member before foo
# test3_gh6.tar.lz:  test3.tar.lz with global before foo in same member
# test3_nn.tar[.lz]: test3.tar[.lz] with zeroed name (no name) in bar member
# test3_sm?.tar.lz:  test3.tar.lz with extended bar member split in 4 ways
# tlz_in_tar1.tar:   1 member (test3.tar.lz) first magic damaged
# tlz_in_tar2.tar:   2 members (foo test3.tar.lz) first magic damaged
# ug32chars.tar.lz:  1 member (foo) with 32-character owner and group names
# ug32767.tar.lz:    1 member (foo) with numerical-only owner and group

# Note that multi-threaded --list succeeds with test_bad2.txt.tar.lz and
# test3_bad3.tar.lz because their headers are intact.
