512c45ef6c Fix -u with absolute paths (e.g., "tar -uf foo.tar /bar") by handling 
pathname edits before comparing pathnames on disk to those in the archive.

Thanks to: Gareth Bailey, Lowell Gilbert

22ede7639d bsdtar now uses the "tree" package instead of "fts" for walking 
directory heirarchies.

5b923e58db A number of fixes to the autoconf-generated build system. In 
particular, acl support is no longer enabled on FreeBSD 4, acl support
should be correctly enabled on Linux, dirent.d_namlen should be
correctly detected on platforms that support it.

Thanks to: Greg Lewis, Juergen Lock, and Jaakko Heinonen

e90e8e4b97 Support path-rewriting options (including --strip-components) for both 
extraction and creation.  While I'm here, fix a bug reported by Garrett
Wollman: when stripping the leading '/' from the path "/", don't produce
an entry with an empty name; produce "." instead.

d14c1502f0 Add --newer-ctime, --newer-mtime, --newer-ctime-than, and --newer-mtime-than 
switches to support selecting files by time of modification.

Special thanks to: Steven M. Bellovin, Rich $alz, and Jim Berets,
	authors of the public-domain getdate.y date-parsing code.

6fc954815f Better low-memory handling: If the link cache runs out of memory, just 
throw out the whole thing and stop tracking links entirely.  That will
break all remaining hardlinks, but should free up enough memory to
let everything finish.

991f1d87bb Move the smart chdir logic into a couple of utility functions in util.c. 
Then use them to provide consistent -C support throughout the program.
Thanks to: Christoph Mallon

8095e9d82b Add --totals option. Unlike gtar, this reports the bytes actually 
written to the archive, not the ones written to the compressor.
For uncompressed archives, these numbers are the same, of course.

62010d3541 A bunch of stuff from Christoph Mellon: 
* Whitespace fixes
  * Check some malloc calls
  * Simplify long_help formatting
  * Spell "LINUX" -> "linux"
  * A few other miscellaneous style improvements

e2fe7499b6 Warn about stripping leading '/' when creating archives. 2004-06-27 18:32:14 +00:00

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.

d24e5e453e Fix "@-" which has apparently been broken for some time. <sigh> 
While I'm here, add in a lot more error-checking around append_archive.

4049589b28 Don't abort immediately on directory change errors. 
Instead, display a warning, clean up, and let main() return the error.
In particular, this means that chdir() problems won't leave broken
archives, though they will prompt an error exit value.

0674dded37 Rename C=dir to -C dir, which is what people expect. 
This requires some non-trivial surgery to the options parsing.

While here, let people who only have getopt() access long options
through the -W longopt=value convention.

a85e1b56bb Set program exit value to 1 if there are any of various errors when 
creating an archive.

b5642237fc Ooops! Previous commit added an over-zealous error check. 
It is, in fact, perfectly legal to not specify a compression when
writing an archive. <sigh>

gname_cache.  Cache negative lookups to dramatically 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.

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.
