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. ;-)
What it is:
A library for reading and writing various streaming archive
formats, especially tar and cpio. Being a library, it should
be easy to incorporate into pkg_* tools, sysinstall, and any
other place that needs to read or write such archives.
Features:
* Full automatic detection of both compression and archive format.
* Extensible internal architecture to make it easy to add new formats.
* Support for "pax interchange format," a new POSIX-standard tar format
that eliminates essentially all of the restrictions of historic formats.
* BSD license
Thanks to: jkh for pushing me to start this work, gordon for
encouraging me to commit it, bde for answering endless style
questions, and many others for feedback and encouragement.
Status: Pretty good overall, though there are still a few rough edges and
the library could always use more testing. Feedback eagerly solicited.
