This commit was manufactured by cvs2svn to create tag

'RELENG_7_0_0_RELEASE'.

This commit was manufactured to restore the state of the 7.0-RELEASE image.

Fix 'bsdtar -t' on tape drives. Libarchive uses the

2007-06-26T03:06:48+00:00

skip() callback to skip over data when reading uncompressed
archives.  This gets invoked, for example, during tar -t
or tar -x with a filename argument.  The revised code
only calls [lf]seek() on regular files, instead of depending
on the kernel to return an error.

Thanks to: bde for explaining the implementation of lseek()
Thanks to: Daniel O'Connor for testing

Fix the copyright notice; it was always intended to be

2007-01-09T08:05:56+00:00

a vanilla 2-clause BSD license, but somehow some confusing
extra verbage get copied from somewhere.

Also, update the copyright dates to 2007 for all of the files.

Prompted by: several questions about what those extra words really mean

Change the client skipper API to use off_t instead of size_t/ssize_t; but

2007-01-05T10:48:18+00:00

wrap this within #if/#else/#endif so that it will only take effect once
ARCHIVE_API_VERSION is increased (which should happen on HEAD some time
between now and when RELENG_7 is branched).

New hooks for reading/writing archives to/from a FILE * or

2006-11-24T02:00:48+00:00

an in-memory buffer.

PR: bin/86742

Add archive_write_open_filename()/archive_read_open_filename() as

2006-11-15T05:33:38+00:00

synonyms for archive_write_open_file()/archive_read_open_file().
The new names are much clearer.

These files no longer use internal APIs, so no longer need to include

2006-11-13T00:29:57+00:00

archive_private.h.

Minor cleanup of the standard read/write I/O modules:

2006-11-13T00:26:45+00:00

 * Use public API, don't access struct archive directly.  (People should be able to copy these into their applications as a template for custom I/O callbacks.)
 * Set "skip" only for regular files.  ("skip" allows the low-level library to catch attempts to add an archive to itself or extract over itself.)
 * Simplify the write_open functions by just calling stat() at the beginning.  Somehow, these functions had acquired some complex logic that tried to avoid the stat() call but never succeeded.

Portability and style fixes:

2006-11-10T06:39:46+00:00

  * Actually use the HAVE__H macros to conditionally include
    system headers.  They've been defined for a long time, but only
    used in a few places.  Now they're used pretty consistently
    throughout.
  * Fill in a lot of missing casts for conversions from void*.
    Although Standard C doesn't require this, some people have been
    trying to use C++ compilers with this code, and they do require it.

Bit-for-bit, the compiled object files are identical, except for
one assert() whose line number changed, so I'm pretty confident I
didn't break anything.  ;-)

Some minor corrections:

2006-09-05T05:59:46+00:00

  * Expose functions for setting the "skip file" dev/ino information
  * Expose functions for setting/querying the block size on reads
  * Correctly propagate errors out of archive_read_close/archive_write_close
  * Update manpage with information about new functions
