b3ea6ecd42 Validate -o usage. Strictly speaking, -o only makes sense with -x,
of course, but I make an effort to accomodate GNU tar scripts that
use -o with -c (with a meaning that totally contradicts SUSv2) by
only issuing a benign warning message in that case.

b9916968df Make the day/month ordering dependent on the current locale by
testing the locale at program startup and setting a flag, then
using that flag to determine appropriate strftime() arguments.

d3d1a208cb Augment the -T handling:
* Add --null option (sort #defines here)
 * Add process_lines function to util.c that reads newline-terminated
   or null-terminated lines (with self-sizing buffers, etc) and iteratively
   invokes a provided function.  Use this to dramatically simplify:
   -T handling for -c, --exclude-from-file, and --include-from-file.
 * Add -T handling to -x (via include_from_file)

Hopefully, this will fix the openoffice port and a couple of
others that rely on -T and --null.

7283cd6959 Refactor name caching to use a common piece of code for uname_cache and
gname_cache.  Cache negative lookups to dramatically improve performance
building archives containing nonexistent uid/gid.

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

9644b0783f For portability, don't rely on libc's strmode(3). <sigh> 2004-05-03 21:05:59 +00:00

020287607f A security issue: An archive containing a symlink to another
directory, then a file with that symlink as a prefix can drop a file
outside of the current directory, which can be a security hole.

Plug this hole by refusing to extract files if a prefix of the
pathname is a symlink.  The -P option disables this check.

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.
