MFC r179791-179792,179800,180269,180271: Several minor portability tweaks:

This brings in all of the updates from libarchive 2.5.4b plus the most critical of the fixes from 2.5.5. Note the internal version is 1.9.25 to mark the fact that it still uses the libarchive 1.x API in order to preserve API/ABI compatibility with previous FreeBSD 6 releases.

MFC r177185,r177186,r177187: Rework the versioning interface again.

The new interface has fewer elements and seems to be easier to use. Of course, I'm retaining the old interface until libarchive 3.x.

MFC libarchive 1.9.

2007-07-05T01:56:41Z

This is identical to libarchive 2.2.3 from -CURRENT, with all of the performance improvements, bug fixes, and new formats, except that: * archive_read_finish() and archive_write_finish() don't return errors * archive_write_data() has a different return type * user-provided skip callbacks have a slightly different signature These differences maintain ABI compatibility with libarchive 1.3.1 (hence the "1" in "1.9") and allows libarchive 1.9 to have the same SHLIB_MAJOR and otherwise serve as a straight replacement for libarchive 1.3.1 (only better). Thanks to: Many, many people who contributed error reports, bug fixes, and suggestions over the last three years. ;-)

MFC: synchronize libarchive with FreeBSD-CURRENT. This includes

2007-01-27T06:44:54Z

the following: * License updates. * Fixes for FreeBSD/arm * New read_open_filename, read_open_memory * New write_open_filename, write_open_memory * Write-blocking cleanup (cperciva@) * Adjust API so read_open/write_open funcs only need public API * Portability improvements (casts, include guards, etc.) * Properly pad sparse archive entries with blocks of zero bytes (cperciva@) * Correct copy of data to file when very large reads are possible * Be more flexible about dir permissions to avoid some fixups * Correct skip handling for entries over 2G (cperciva@) * ISO9660: skip entries faster, support entries over 2G * Tar: correct position accounting when skipping large entries (cperciva@) * Support unbuffered write as a special case (blocksize=0) (cperciva@) * Documentation corrections, improvements * Spelling corrections (cperciva@) * Improve some internal error returns A few of these changes break the API/ABI and are therefore conditional on the version number. FreeBSD 6 will continue to use libarchive 1.x, which will continue to use the old API/ABI. When all of these changes are ready, the libarchive version number will be changed in -CURRENT to enable the new API. Hopefully, this will allow the actual source to remain identical between FreeBSD 6 and 7; only the version parameters in the Makefile will be different.

Implement a custom print formatter (archive_string_vsprintf)

for libarchive error messages. Mostly, this avoids a portability headache related to copying va_list arguments (some FreeBSD 5 platforms require va_copy; FreeBSD 4 doesn't support va_copy at all). It also dramatically reduces the size of libarchive for embedded applications: a minimal "untar" program using libarchive can now be under 64k statically linked (as opposed to ~100k using library *printf() functions). MFC after: 14 days

Add __archive_strappend_int to format a decimal

number into a variable-length archive_string.

Remove the unused archive_string_sprintf() utility function.

Many fixes:

* Disabled shared-library building, as some API breakage is still likely. (I didn't realize it was turned on by default.) If you have an existing /usr/lib/libarchive.so.2, I recommend deleting it. * Pax interchange format now correctly stores and reads UTF8 for extended attributes. In particular, pax format can portably handle arbitrarily long pathnames containing arbitrary characters. * Library compiles cleanly at -O2, -O3, and WARNS=6 on all FreeBSD-CURRENT platforms. * Minor portability improvements inspired by Juergen Lock and Greg Lewis. (Less reliance on stdint.h, isolating of various portability-challenged constructs.) * archive_entry transparently converts multi-byte <-> wide character strings, allowing clients and format handlers to deal with either one, as appropriate. * Support for reading 'L' and 'K' entries in standard tar archives for star compatibility. * Recognize (but don't yet handle) ACL entries from Solaris tar. * Pushed format-specific data for format readers down into format-specific storage and out of library-global storage. This should make it easier to maintain individual formats without mucking with the core library management. * Documentation updates to track the above changes. * Updates to tar.5 to correct a few mistakes and add some additional information about GNU tar and Solaris tar formats. Notes: * The basic 'tar' reader is getting more general; there's not much point in keeping the 'gnutar' reader separate. Merging the two would lose a bunch of duplicate code. * The libc ACL support is looking increasingly inadequate for my needs here. I might need to assemble some fairly significant code for parsing and building ACLs.
