Initial import of libarchive. 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.

Many fixes. Portability: Thanks to Juergen Lock, libarchive now compiles cleanly on Linux. Along the way, I cleaned up a lot of error return codes and reorganized some code to simplify conditional compilation of certain sections. Bug fixes: * pax format now actually stores filenames that are 101-154 characters long. * pax format now allows newline characters in extended attributes (this fixes a long-standing bug in ACL handling) * mtime/atime are now restored for directories * directory list is now sorted prior to fix-up to permit correct restore of non-writable dir heirarchies

Portability and style fixes: * Actually use the HAVE_<header>_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. ;-)

Start to address the race issue between restoring a file's contents 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).

Performance: If the dir mode requested is "reasonable", then just restore it directly and skip chmod() during the post-extract fixup. In particular, bsdtar -xm now completely skips the post-extract fixup for directories, which produces a noticable speedup in that case.

Refactor the extraction code somewhat. In particular, push extract data down into archive_read_extract.c and out of the library-global archive_private.h; push dir-specific mode/time fixup down into dir restore function; now that the fixup list is file-local, I can use somewhat more natural naming. Oh, yeah, update a bunch of comments to match current reality.

I think this is my fourth complete rewrite of the dir-creation code. <whew!> This version handles all of the following edge cases: * Restoring explicit dirs with 000 permissions (star fails this test) * Restore of implicit or explicit dirs when umask=777 (gtar and star both fail this test) * Restoring dir paths containing "." and ".." components This version initially creates all dirs with permission 700 (ignoring umask), then does a post-extract "fixup" pass to set the correct permissions (which may or may not depend on umask, depending on the restore flags and whether it's an explicit or implicit dir). Permissions are restored depth-first so that permissions within non-writable dirs can be correctly restored. (The depth-sorting does correctly account for dirs with ".." components.)

return (r);
Unify mkdirpath (used to automatically create missing parent dirs) and read_extract_dir (which creates directories in the archive). This brings a number of advantages: * FINALLY fix the problems creating dirs ending in "/." <sigh> * Missing parent dirs now get created securely, just like explicit dirs. (Created 0700 initially, then edited to 0755 at end of extraction.) * Eliminate some duplicate code and some weird special cases. While I'm cleaning, inline the regular-file creation code as well.

Initial import of libarchive. What it is: A library for reading and writing various streaming archive formats, especially tar and cpio.

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.

Overhauled ACL support. This makes us compatible with 'star' ACL handling, though there's still a bit more work needed in this area. Added 'write_open_fd' and 'read_open_fd' to simplify, e.g., tar's u and r modes. Eliminated old 'write_open_file_position' as a bad idea. (It required closing/reopening files to do updates, which led to unpleasant implications.) Various other minor fixes, API tweaks, etc.
