'RELENG_6_0_0_RELEASE'.

This commit was manufactured to restore the state of the 6.0-RELEASE image.

Don't return NULL if there's no error message;

2005-02-23T06:57:04+00:00

return a generic text message instead.
(Someday, I'll track down all the places that
are generating errors but not recording messages. ;-/

Thanks to: Jaakko Heinonen

Eliminate reliance on non-portable by implementing a very

2004-08-14T03:45:45+00:00

simple errx() function.
Improve behavior when bzlib/zlib are missing by detecting and
issuing an error message on attempts to read gzip/bzip2 compressed
archives.

Add some functions to query basic facts about the library:

2004-07-24T20:08:26+00:00

   archive_version: Returns a text string, e.g., "libarchive 1.00.000"
   archive_api_version: Returns the SHLIB major version
   archive_api_feature: Returns a feature number useful for answering
     questions such as "Is this recent enough to do XXX?"

The last two also have macros defined in archive.h, so you can compare
the compile-time and run-time environments.  (In particular, you can
compare ARCHIVE_API_VERSION to archive_api_version() to detect library
version mismatches.)

With these in hand, it will soon be time to turn on the
shared-library version of libarchive...  stay tuned.

Add statistics: track offset in compressed and uncompressed archive,

2004-04-28T04:41:27+00:00

provide an interface for the client to query this information.

More work on ACLs: fix error in archive_entry's ACL parsing code,

2004-04-12T01:16:16+00:00

  try to set ACLs even if fflag restore fails, first cut at reading
  Solaris tar ACLs

Code improvement: merge gnu tar read support into main tar reader;
  this eliminates a lot of duplicate code and generalizes the tar
  reader to handle formats with GNU-like extensions.

Style: Makefile cleanup, eliminate 'dmalloc' references, remove 'tartype'
  from archive_entry (this makes archive_entry more format-agnostic)

Thanks to: David Magda for providing Solaris tar test files

Just use autoconf-compatible feature macros; don't try to be clever.

Bug: Standard C still requires declarations to precede statements.

2004-03-20T22:35:33+00:00

Portability: Eliminate an accidental __unused, accomodate
  systems with non-POSIX strerror_r

Many fixes.

Portability: Thanks to Juergen Lock, libarchive now compiles cleanly
on Linux.  Along the way, I cleaned up a lot of error return codes and
reorganized some code to simplify conditional compilation of certain
sections.

Bug fixes:
  * pax format now actually stores filenames that are 101-154
    characters long.
  * pax format now allows newline characters in extended attributes
    (this fixes a long-standing bug in ACL handling)
  * mtime/atime are now restored for directories
  * directory list is now sorted prior to fix-up to permit
    correct restore of non-writable dir heirarchies

Initial import of libarchive.

2004-02-09T23:22:54+00:00

What it is:
   A library for reading and writing various streaming archive
   formats, especially tar and cpio.  Being a library, it should
   be easy to incorporate into pkg_* tools, sysinstall, and any
   other place that needs to read or write such archives.

Features:
  * Full automatic detection of both compression and archive format.
  * Extensible internal architecture to make it easy to add new formats.
  * Support for "pax interchange format," a new POSIX-standard tar format
    that eliminates essentially all of the restrictions of historic formats.
  * BSD license

Thanks to: jkh for pushing me to start this work, gordon for
  encouraging me to commit it, bde for answering endless style
  questions, and many others for feedback and encouragement.

Status: Pretty good overall, though there are still a few rough edges and
  the library could always use more testing.  Feedback eagerly solicited.
