755e3f9b2e Improve help handling: 
* --help produces long help message on systems with getopt_long
   * -h with no other options also produces long help message
     (If a mode is specified, -h has its usual meaning.)

e5572b4b7c Correction: -h should be a synonym for -L, not -H. 
(as specified by Linux Standards Base, GNU tar, and 4.4BSD documentation)

de10ed4154 Permit (but ignore) -Z with -x or -t, now that libarchive 
recognizes and decompresses .Z format.

8df3c224c0 Provide framework for exiting with non-zero value on non-critical errors. 2004-05-27 04:30:59 +00:00

26eddc7f41 Add --no-same-owner as a synonym for -o. 
Note that bsdtar's -o (which follows SUSv2) is not the same as GNU tar's -o.
In GNU tar, -o and --no-same-owner are not synonyms.

656e70b49a Accept (but ignore) GNU tar's -B option. bsdtar never 
needs it, but it does no harm for people to specify it.

088bdb251d Propagate struct bsdtar down into a lot more places. 
Move global progname variable into struct bsdtar.

4a07f42b98 Make symlink protection a bit more useful: 
* Remove terminal symlinks so they can be replaced.
  * If -U, remove intermediate symlinks as well
  * Otherwise, refuse the extraction

81f3488f97 Add --unlink and --unlink-first synonyms for -U 
Make indentation of tar_longopts array more consistent.

cc52bf3428 --help is only supported if you have getopt_long(). 
This allows bsdtar to compile on FreeBSD 4.x.

855e109158 As suggested by Julian Elischer, use a self-sizing hash 
table for the hardlink cache.  This dramatically improves
performance when archiving millions of hardlinked files.

While I'm here, clean up some style bugs (per Bruce Evans)
and clarify some comments.

17834543c8 A simple cache of uid->uname lookups and gid->gname lookups eliminates 
almost 1/2 of the CPU time required to create an uncompressed archive
and makes a noticable reduction in wallclock time.

de60e4436b Manpage changes suggested by Irina Liakh. 
Also, add -h as a synonym for -H, for Linux Standards Base compliance.

4cbbc3a35e Add DPADD to Makefile (thanks to Andrey for pointing this out). 
Generally clean up Makefile, remove dmalloc references from source
(there are better ways to do this than pollute the FreeBSD src tree).

f6f4796250 Allow arguments to appear in any order. 
While I'm here, add a couple of extra sanity-checks to
the argument parsing (reject -j -z, for instance) and
update the docs a bit.

Requested by: most everyone ;-)
