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.

f0e6a2b96d Minor corrections to error handling and user notifications:
* Move format/compression reporting to end of output, since
  we don't always know the input format until then.
* Set bsdtar exit value to 1 if any file could not be restored.
* Generate gtar-style warning when stripping leading '/' characters.
* Warn when removing symlinks.

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.

a25502627d Set errno to 0 before calling getpwuid/getgrgid, so that error
messages will be displayed only when there is, in fact, an error.

9d77c5f29c Speed up safe_fprintf by copying to a temp buffer, then writing
blocks at a time, rather than using putc().

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

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

bf0c356cdf Contrariwise, Linux sys/stat.h doesn't define mode_t and friends,

6e8b30b778 Include local copies of fts.c and fts.h to be used ONLY on non-FreeBSD
systems.  The fts.h here is an exact copy of include/fts.h (except for
an initial explanatory comment and the revision tags, of course).  The
fts.c here is slightly modified from lib/libc/gen/fts.c so it can
compile correctly on non-FreeBSD systems.

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.

6c6b3d9aa5 -U is now implemented. (It's been recognized by bsdtar for a while;
now libarchive actually supports the underlying request.)

749029a437 Update write.c to follow recent API changes to libarchive.
Also, bump up the default copy buffer from 8k to 64k
to improve performance.

7e02198e95 Fix username/groupname cache so it returns a name that
was just looked up by get{pw,gr}id().  Otherwise, it
returns a NULL name unless it's already in the cache.

Credit to Juergen Lock.

97c4c5308b Allow brave souls to install bsdtar as the
default "tar" command by defining WITH_BSDTAR.

Note: "gtar" and "bsdtar" commands both exist regardless.

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.

907d74bb26 Eliminate a lot of malloc/free calls by using
a stack-allocated buffer for safe_fprintf formatting.
Only if the result is too large do we resort to malloc.

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.
