This commit was manufactured by cvs2svn to create tag

'RELENG_6_0_0_RELEASE'.

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

Remove the C99-specific func that is one of the few barrier to

2005-06-01T15:52:39+00:00

compiling on IRIX and Solaris.  Remove the "archive_check_magic" macro
that existed only to provide __func__ to the underlying __archive_check_magic
function.

A number of improvements to ZIP support.

2005-04-06T04:19:30+00:00

  * Handles entries with compressed size >2GB (signed/unsigned cleanup)
  * Handles entries with compressed size >4GB ("ZIP64" extension)
  * Handles Unix extensions (ctime, atime, mtime, mode, uid, etc)
  * Format-specific "skip data" override allows ZIP reader to skip
    entries without decompressing them, which makes "tar -t"
    a lot faster.
  * Handles "length-at-end" entries generated by, e.g., "zip -r - foo"

Many thanks to: Dan Nelson, who contributed the code and test files for
   the first three items above and suggested the fourth.

Clear the error buffer on entry

to archive_read_next_header so the
next error doesn't just get appended.

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.

Split archive_{read,write}_finish into separate "close" (finish the archive

2004-08-07T19:22:50+00:00

and close it) and "finish" (destroy the object) functions.   For backwards
compat and simplicity, have "finish" invoke "close" transparently if needed.
This allows clients to close the archive and check end-of-operation
statistics before destroying the object.

Correctly reset archive_read_data state everytime a header is read.

Be more careful about the initial read (used for "tasting" the compression):

2004-06-04T01:36:10+00:00

  * Check for and return input errors
  * Treat empty file (zero-length read) as a fatal error

Refactor the extraction code somewhat. In particular,

2004-06-03T23:29:47+00:00

push extract data down into archive_read_extract.c and out
of the library-global archive_private.h; push dir-specific
mode/time fixup down into dir restore function; now that the
fixup list is file-local, I can use somewhat more natural
naming.

Oh, yeah, update a bunch of comments to match current reality.

Refactor read_data:

2004-06-02T08:14:43+00:00

 * New read_data_block is both sparse-file aware and uses zero-copy semantics
 * Push read_data_block down into specific formats (opens door to
   various encoded entry bodies, such as zip or gtar -S)
 * Reimplement read_data, read_data_skip, read_data_into_fd in terms
   of new read_data_block.
 * Update documentation
It's unfortunate that I couldn't just call the new interface
archive_read_data, but didn't want to upset the API that much.
