feedback, but the 2.5 branch is shaping up nicely.)
In addition to many small bug fixes and code improvements:
* Another iteration of versioning; I think I've got it right now.
* Portability: A lot of progress on Windows support (though I'm
not committing all of the Windows support files to FreeBSD CVS)
* Explicit tracking of MBS, WCS, and UTF-8 versions of strings
in archive_entry; the archive_entry routines now correctly return
NULL only when something is unset, setting NULL properly clears
string values. Most charset conversions have been pushed down to
archive_string.
* Better handling of charset conversion failure when writing or
reading UTF-8 headers in pax archives
* archive_entry_linkify() provides multiple strategies for
hardlink matching to suit different format expectations
* More accurate bzip2 format detection
* Joerg Sonnenberger's extensive improvements to mtree support
* Rough support for self-extracting ZIP archives. Not an ideal
approach, but it works for the archives I've tried.
* New "sparsify" option in archive_write_disk converts blocks of nulls
into seeks.
* Better default behavior for the test harness; it now reports
all failures by default instead of coredumping at the first one.
that I've been working on but put off committing until after the
RELENG_7 branch, including:
* New manpages: cpio.5 mtree.5
* New archive_entry_strmode()
* New archive_entry_link_resolver()
* New read support: mtree format
* Internal API change: read format auction only runs once
* Running the auction only once allowed simplifying a lot of bid logic.
* Cpio robustness: search for next header after a sync error
* Support device nodes on ISO9660 images
* Eliminate a lot of unnecessary copies for uncompressed archives
* Corrected handling of new GNU --sparse --posix formats
* Correctly handle a zero-byte write to a compressed archive
* Fixed memory leaks
Many of these improvements were motivated by the upcoming bsdcpio
front-end.
There have also been extensive improvements to the libarchive_test
test harness, which I'll commit separately.
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
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.
GNU tar sparse files, people have extended cpio) and clarify an
important detail about pax format (that ustar-compliant archivers
can mostly read pax archives correctly).
MFC after: 7 days
archive formats supported by libarchive, with some information about
the relative strengths and weaknesses of each format and notes about
issues with libarchive's support for those formats.
This page should make it unnecessary to list all of the libarchive
formats in the manpage of each program that uses libarchive.
Such programs can simply refer to libarchive-formats(5).
