* "compression_program" support uses an external program
* Portability: no longer uses "struct stat" as a primary
data interchange structure internally
* Part of the above: refactor archive_entry to separate
out copy_stat() and stat() functions
* More complete tests for archive_entry
* Finish archive_entry_clone()
* Isolate major()/minor()/makedev() in archive_entry; remove
these from everywhere else.
* Bug fix: properly handle decompression look-ahead at end-of-data
* Bug fixes to 'ar' support
* Fix memory leak in ZIP reader
* Portability: better timegm() emulation in iso9660 reader
* New write_disk flags to suppress auto dir creation and not
overwrite newer files (for future cpio front-end)
* Simplify trailing-'/' fixup when writing tar and pax
* Test enhancements: fix various compiler warnings, improve
portability, add lots of new tests.
* Documentation: document new functions, first draft of
libarchive_internals.3

This is a no-op as far as FreeBSD is concerned, but makes libarchive
more autoconf-friendly.

* use "AR_GNU" as the format name instead of AR_SVR4 (it's what everyone is going to call it anyway)
* Simplify numeric parsing to unsigned (none of the numeric values should ever be negative); don't run off end of numeric fields.
* Finish parsing the common header fields before the next I/O request (which might dump the contents)
* Be smarter about format guessing and trimming filenames.
* Most of the magic values are only used in one place, so just inline them.
* Many more comments.
* Be smarter about handling damaged entries; return something reasonable.
* Call it a "filename table" instead of a "string table"
* Update tests.
Enable selection of 'ar', 'arbsd', and 'argnu' formats by name
(this allows bsdtar to create ar format archives).
The 'ar' writer still needs some work; it should reject
entries that aren't regular files and should probably also
strip leading paths from filenames.

N.B. 'ar' format support is broken right now, it's not
passing tests. If I can't find the problem soon, I'll
back out the last commit.

for directories. bsdtar used to add this, but that recently got
lost somehow. So now I'm adding it back in libarchive.
The only odd part of doing this in libarchive: Adding a directory to
a tar archive and then reading it back again can yield a different name.
Add a test case to exercise some boundary conditions with
tar filenames and ensure that trailing slashes are added to
dir names only as necessary.
Thanks to: Oliver Lehmann for bringing this regression to my attention.

Don't change permissions on an existing dir unless _EXTRACT_PERM
is requested.
In particular, bsdtar -x should not edit mode of existing dirs
now; bsdtar -xp will.

* Only try to remove the existing item if we're not restoring a directory.
* If unlink fails, try rmdir next.
This should fix the broken --unlink option in bsdtar.

* The ACL formatter was mis-formatting entries which had a
user/group ID but no name. Make the parser tolerant of
these, so that old archives can be correctly restored;
fix the formatter to generate correct entries.
* Fix overwrite detection by introducing a new "FAILED" return
code that indicates the current entry cannot be continued
but the archive as a whole is still sound.
* Header cleanup: Remove some unused headers, add some that
are required with new Linux systems.

* libarchive_test program exercises many of the core features
* Refactored old "read_extract" into new "archive_write_disk", which
uses archive_write methods to put entries onto disk. In particular,
you can now use archive_write_disk to create objects on disk
without having an archive available.
* Pushed some security checks from bsdtar down into libarchive, where
they can be better optimized.
* Rearchitected the logic for creating objects on disk to reduce
the number of system calls. Several common cases now use a
minimum number of system calls.
* Virtualized some internal interfaces to provide a clearer separation
of read and write handling and make it simpler to override key
methods.
* New "empty" format reader.
* Corrected return types (this ABI breakage required the "2.0" version bump)
* Many bug fixes.

* If write block size is zero, don't block at all.
This supports the unusual requirement of applications
that need "no-delay" writes.
* Expose _write_finish_entry() to give such applications more
control over write boundaries. (Normal applications do not
need this, as entries are completed automatically.)
* Correct the type of write callbacks; this is a minor API
change that does not affect the ABI.
* Correct the error handling in _write_next_header() around
completing the previous entry.
* Correct the documentation for block-size markers: Remove
docs for the long-defunct _read_set_block_size(); document
all of the write block size manipulators.

traditional shortcut of defining on-disk layouts using structures of
character arrays. Unfortunately, as recently discussed on cvs-all@,
this usage is not actually sanctioned by the standards and
specifically fails on GCC/arm (unless your data structures happen to
be "naturally aligned").
The new code defines offsets/sizes for data fields and accesses
them using explicit pointer arithmetic, instead of casting to
a structure and accessing structure fields. In particular,
the new code is now clean with WARNS=6 on arm.

This commit implements storing/reading POSIX.1e-style extended
attribute information in "pax" format archives. An outline of the
storage format is in the tar.5 manpage. The archive_read_extract()
function has code to restore those archives to disk for Linux; FreeBSD
implementation is forthcoming.
Many thanks to Jaakko Heinonen for finding flaws in earlier
proposals and doing the bulk of the coding in this work.

archiver for Fourth Edition through Sixth Edition Unix; it was
replaced by tar in Seventh Edition. (First Edition through
Third Edition used "tap.")
Unfortunately, tp was not so very standard; there were a
few different variants. The code here attempts to support
what I believe were the most common variants.
tp support is not yet enabled by archive_read_support_format_all(),
as I'm not yet entirely comfortable with the detection
heuristics. People interested in experimenting can
add archive_read_support_format_tp() just after any calls
to archive_read_support_format_all() in bsdtar to see how
well this works.
TODO: tp format is roughly similar in structure to dump/restore
archive formats used by many systems. It should be possible
to generalize this code to handle many dump/restore variants.
Format detection heuristics are going to be rough, though.
Thanks to: Warren Toomey, whose very basic tp extraction programs
and documentation made this possible.

systems (or on FreeBSD systems when using ports).
2) Overhaul the versioning logic. In particular,
SHLIB_MAJOR number is now computed as "major+minor",
which ensures library versions are the same for
the FreeBSD build system and the portable
libtool/autoconf/automake build system.

(wchar_t is defined in stddef.h, and only two files need more than that.)
Portability: Since the wchar requirements are really quite modest,
it's easy to define basic replacements for wcslen, wcscmp, wcscpy,
etc, for use on systems that lack <wchar.h>. In particular, this allows
libarchive to be used on older OpenBSD systems.

and restoring the metadata. In particular, the metadata-restore
functions now all accept a file descriptor and a pathname. If the
file descriptor is set and the platform supports the appropriate
syscall, restore the metadata through the file descriptor. Otherwise,
restore it through the pathname. This is complicated by varying
syscall support (FreeBSD has an fchmod(2) but no fchflags(2), for
example) and because non-file entries don't have an fd to use in
restoring attributes (for example, mknod(2) doesn't return a file
handle).

This seems to be able to extract a TOC and extract files from
the couple of ISO images I've tested it with.
Treat this as experimental proof-of-concept code for the
moment. There are still a bunch of debug messages (there
are a few oddities in ISO9660 that I haven't yet figured
out how to handle), a lot of bugs to be addressed (this
code leaks memory very badly), and a lot of missing features (no
Rockridge support, in particular). I'd appreciate
feedback from anyone who understands ISO9660 format
better than I do. ;-)
