MFC: A number of interrelated changes that I'm too tired to tease

apart into separate MFCs. These have all been in -CURRENT for quite some time.

MFC: libarchive 2.4.12

2008-02-11T00:31:09Z

* Formats are now only bid once per file, not once per entry (Affects archive_read.c, most format readers, internals manpage) * Correct tar/cpio history in libarchive_formats manpage * Avoid unnecessary copies in {write,read}_compression_none (significant performance boost for uncompressed archives!) * Protect against zero-length writes in gzip/bzip2 compressors * Tar reader: improve hardlink length heuristics, GNU tar --posix --sparse support, related fixes to SCHILY.realsize handling * Cpio reader: recover from sync errors * Cpio writer: pad symlinks properly in newc format * Ar writer: close out empty archive correctly * Zip reader: ignore PK00 header, code cleanups from des@ * Iso9660 reader: support device node entries * archive_write_disk: support hardlinks with bodies, enforce maximum file size * Reconnect progress callback from archive_read_extract() * New: archive_entry_strmode() * New: mtree reader * New: "linkresolver" makes it easier to do hardlink resolution * UUencode test reference files (be nice to CVS) * New test: exercise very large entries (2G up to 1T) in tar archives * New test: Detailed verification of cpio odc and newc formats * New test: Various strategies for restoring multiple links to a file * New tests: Various compatibility checks against gzip, zip, old tar, etc. * New test: cpio recovery from damaged archives * New test: mtree reading * Improved statistics reporting from test harness * Plus minor portability improvements

New "version stamp" simplifies determining the exact version

of libarchive being used. I've been taking advantage of this with a recent round of updates to libarchive_test so that it can test older and newer versions of the library. Approved by: re (Ken Smith)

libarchive 2.2.3

2007-05-29T01:00:21Z

* "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 MFC after: 14 days Thanks to: Joerg Sonnenberger (compression_program) Thanks to: Kai Wang (ar) Thanks to: Colin Percival (many small fixes) Thanks to: Many others who sent me various patches and problem reports.

libarchive 2.0

2007-03-03T07:37:37Z

* 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.

Fix the copyright notice; it was always intended to be

2007-01-09T08:05:56Z

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

Portability and style fixes:

2006-11-10T06:39:46Z

* 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. ;-)

Add a lot of error checks, based on the patches provided by Dan Lukes.

Also fixes a memory leak reported by Andrew Turner. PR: bin/83476 Thanks to: Dan Lukes, Andrew Turner

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

2005-02-23T06:57:04Z

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
