Feb, 2009: Joliet support by Andreas Henriksson. Jan/Feb, 2009: New options framework by Michihiro. Feb, 2009: High-res timestamps on Tru64, AIX, and GNU Hurd, by Björn Jacke. Jan 18, 2009: Extended attributes work on FreeBSD and Linux now with pax format. Jan 07, 2009: New archive_read_disk_entry_from_file() knows about ACLs, extended attributes, etc so that bsdtar and bsdcpio don't require such system-specific knowledge. Jan 03, 2009: Read filter system extensively refactored. In particular, read filter pipelines are now built out automatically and individual filters should be much easier to implement. Documentation on the Googlecode Wiki explains how to implement new filters. Dec 28, 2008: Many Windows/Visual Studio fixes from Michihiro NAKAJIMA. Dec 28, 2008: Main libarchive development moved from FreeBSD Perforce server to Google Code. This should make it easier for more people to participate in libarchive development. Dec 28, 2008: libarchive 2.6.0 released Dec 25, 2008: libarchive 2.5.905a released Dec 10, 2008: libarchive 2.5.904a released Dec 04, 2008: libarchive 2.5.903a released Nov 09, 2008: libarchive 2.5.902a released Nov 08, 2008: libarchive 2.5.901a released Nov 08, 2008: Start of pre-release testing for libarchive 2.6 Nov 07, 2008: Read filter refactor: The decompression routines just consume and produce arbitrarily-sized blocks. The reblocking from read_support_compression_none() has been pulled into the read core. Also, the decompression bid now makes multiple passes and stacks read filters. Oct 21, 2008: bsdcpio: New command-line parser. Oct 19, 2008: Internal read_ahead change: short reads are now an error Oct 06, 2008: bsdtar: option parser no longer uses getopt_long(), gives consistent option parsing on all platforms. Sep 19, 2008: Jaakko Heinonen: shar utility built on libarchive Sep 17, 2008: Pedro Giffuni: birthtime support Sep 17, 2008: Miklos Vajna: lzma reader and test. Note: I still have some concerns about the auto-detection (LZMA file format doesn't support auto-detection well), so this is not yet enabled under archive_read_support_compression_all(). For now, you must call archive_read_support_compression_lzma() if you want LZMA read support. Sep 11, 2008: Ivailo Petrov: Many fixes to Windows build, new solution files Jul 26, 2008: archive_entry now tracks which values have not been set. This helps zip extraction (file size is often "unknown") and time restores (tar usually doesn't know atime). Jul 26, 2008: Joerg Sonnenberger: Performance improvements to shar writer Jul 25, 2008: Joerg Sonnenberger: mtree write support Jul 02, 2008: libarchive 2.5.5 released Jul 02, 2008: libarchive 2.5.5b released Jul 01, 2008: bsdcpio is being used by enough people, we can call it 1.0.0 now Jun 20, 2008: bsdcpio: If a -l link fails with EXDEV, copy the file instead Jun 19, 2008: bsdcpio: additional long options for better GNU cpio compat Jun 15, 2008: Many small portability and bugfixes since 2.5.4b. May 25, 2008: libarchive 2.5.4b released May 21, 2008: Joerg Sonnenberger: fix bsdtar hardlink handling for newc format May 21, 2008: More progress on Windows building. Thanks to "Scott" for the Windows makefiles, thanks to Kees Zeelenberg for code contributions. May 21, 2008: Fix a number of non-exploitable integer and buffer overflows, thanks to David Remahl at Apple for pointing these out. May 21, 2008: Colin Percival: SIGINFO or SIGUSR1 to bsdtar prints progress info May 16, 2008: bsdtar's test harness no longer depends on file ordering. This was causing spurious test failures on a lot of systems. Thanks to Bernhard R. Link for the diagnosis. May 14, 2008: Joerg Sonnenberger: -s substitution support for bsdtar May 13, 2008: Joerg Sonnenberger: Many mtree improvements May 11, 2008: Joerg Sonnenberger: fix hardlink extraction when hardlinks have different permissions from original file April 30, 2008: Primary libarchive work has been moved into the FreeBSD project's Perforce repository: http://perforce.freebsd.org/ The libarchive project can be browsed at //depot/user/kientzle/libarchive-portable Direct link: http://preview.tinyurl.com/46mdgr May 04, 2008: libarchive 2.5.3b released * libarchive: Several fixes to link resolver to address bsdcpio crashes * bsdcpio: -p hardlink handling fixes * tar/pax: Ensure ustar dirnames end in '/'; be more careful about measuring filenames when deciding what pathname fields to use * libarchive: Mark which entry strings are set; be accurate about distinguishing empty strings ("") from unset ones (NULL) * tar: Don't crash reading entries with empty filenames * libarchive_test, bsdtar_test, bsdcpio_test: Better detaults: run all tests, delete temp dirs, summarize repeated failures * -no-undefined to libtool for Cygwin * libarchive_test: Skip large file tests on systems with 32-bit off_t * iso9660: Don't bother trying to find the body of an empty file; this works around strange behavior from some ISO9660 writers * tar: allow -r -T to be used together * tar: allow --format with -r or -u * libarchive: Don't build archive.h May 04, 2008: Simplified building: archive.h is no longer constructed This may require additional #if conditionals on some platforms. Mar 30, 2008: libarchive 2.5.1b released Mar 15, 2008: libarchive 2.5.0b released Mar 15, 2008: bsdcpio now seems to correctly write hardlinks into newc, ustar, and old cpio archives. Just a little more testing before bsdcpio 1.0 becomes a reality. Mar 15, 2008: I think the new linkify() interface is finally handling all known hardlink strategies. Mar 15, 2008: Mtree read fixes from Joerg Sonnenberger. Mar 15, 2008: Many new bsdtar and bsdcpio options from Joerg Sonnenberger. Mar 15, 2008: test harnesses no longer require uudecode; they now have built-in decoding logic that decodes the reference files as they are needed. Mar 14, 2008: libarchive 2.4.14 released; identical to 2.4.13 except for a point fix for gname/uname mixup in pax format that was introduced with the UTF-8 fixes. Feb 26, 2008: libarchive 2.4.13 released Feb 25, 2008: Handle path, linkname, gname, or uname that can't be converted to/from UTF-8. Implement "hdrcharset" attribute from SUS-2008. Feb 25, 2008: Fix name clash on NetBSD. Feb 18, 2008: Fix writing empty 'ar' archives, per Kai Wang Feb 18, 2008: [bsdtar] Permit appending on block devices. Feb 09, 2008: New "linkify" resolver to help with newc hardlink writing; bsdcpio still needs to be converted to use this. Feb 02, 2008: Windows compatibility fixes from Ivailo Petrov, Kees Zeelenberg Jan 30, 2008: Ignore hardlink size for non-POSIX tar archives. Jan 22, 2008: libarchive 2.4.12 released Jan 22, 2008: Fix bad padding when writing symlinks to newc cpio archives. Jan 22, 2008: Verify bsdcpio_test by getting it to work against GNU cpio 2.9. bsdcpio_test complains about missing options (-y and -z), format of informational messages (--version, --help), and a minor formatting issue in odc format output. After this update, bsdcpio_test uncovered several more cosmetic issues in bsdcpio, all now fixed. Jan 22, 2008: Experimental support for self-extracting Zip archives. Jan 22, 2008: Extend hardlink restore strategy to work correctly with hardlinks extracted from newc cpio files. (Which store the body only with the last occurrence of a link.) Dec 30, 2007: libarchive 2.4.11 released Dec 30, 2007: Fixed a compile error in bsdcpio on some systems. Dec 29, 2007: libarchive 2.4.10 released Dec 29, 2007: bsdcpio 0.9.0 is ready for wider use. Dec 29, 2007: Completed initial test harness for bsdcpio. Dec 22, 2007: libarchive 2.4.9 released Dec 22, 2007: Implement the remaining options for bsdcpio: -a, -q, -L, -f, pattern selection for -i and -it. Dec 13, 2007: libarchive 2.4.8 released Dec 13, 2007: gzip and bzip2 compression now handle zero-byte writes correctly, Thanks to Damien Golding for bringing this to my attention. Dec 12, 2007: libarchive 2.4.7 released Dec 10, 2007: libarchive 2.4.6 released Dec 09, 2007: tar/test/test_copy.c verifies "tar -c | tar -x" copy pipeline Dec 07, 2007: Fix a couple of minor memory leaks. Dec 04, 2007: libarchive 2.4.5 released Dec 04, 2007: Fix cpio/test/test_write_odc by setting the umask first. Dec 03, 2007: libarchive 2.4.4 released Dec 03, 2007: New configure options --disable-xattr and --disable-acl, thanks to Samuli Suominen. Dec 03, 2007: libarchive 2.4.3 released Dec 03, 2007: Thanks to Lapo Luchini for sending me a ZIP file that libarchive couldn't handle. Fixed a bug in handling of "length at end" flags in ZIP files. Dec 03, 2007: Fixed bsdcpio -help, bsdtar -help tests. Dec 02, 2007: First cut at real bsdtar test harness. Dec 02, 2007: libarchive 2.4.2 released Dec 02, 2007: libarchive 2.4.1 released Dec 02, 2007: Minor fixes, rough cut of mdoc-to-man conversion for man pages. Oct 30, 2007: libarchive 2.4.0 released Oct 30, 2007: Minor compile fix thanks to Joerg Schilling. Oct 30, 2007: Only run the format auction once at the beginning of the archive. This is simpler and supports better error recovery. Oct 29, 2007: Test support for very large entries in tar archives: libarchive_test now exercises entries from 2GB up to 1TB. Oct 27, 2007: libarchive 2.3.5 released Oct 27, 2007: Correct some unnecessary internal data copying in the "compression none" reader and writer; this reduces user time by up to 2/3 in some tests. (Thanks to Jan Psota for publishing his performance test results to GNU tar's bug-tar mailing list; those results pointed me towards this problem.) Oct 27, 2007: Fix for skipping archive entries that are exactly a multiple of 4G on 32-bit platforms. Oct 25, 2007: Fix for reading very large (>8G) tar archives; this was broken when I put in support for new GNU tar sparse formats. Oct 20, 2007: Initial work on new pattern-matching code for cpio; I hope this eventually replaces the code currently in bsdtar. Oct 08, 2007: libarchive 2.3.4 released Oct 05, 2007: Continuing work on bsdcpio test suite. Oct 05, 2007: New cpio.5 manpage, updates to "History" of bsdcpio.1 and bsdtar.1 manpages. Oct 05, 2007: Fix zip reader to immediately return EOF if you try to read body of non-regular file. In particular, this fixes bsdtar extraction of zip archives. Sep 30, 2007: libarchive 2.3.3 released Sep 26, 2007: Rework Makefile.am so that the enable/disable options actually do the right things. Sep 26, 2007: cpio-odc and cpio-newc archives no longer write bodies for non-regular files. Sep 26, 2007: Test harness for bsdcpio is in place, needs more tests written. This is much nicer than the ragtag collection of test scripts that bsdtar has. Sep 20, 2007: libarchive 2.3.2 released Sep 20, 2007: libarchive 2.3.1 broke bsdtar because the archive_write_data() fix was implemented incorrectly. Sep 16, 2007: libarchive 2.3.1 released Sep 16, 2007: Many fixes to bsdcpio 0.3: handle hardlinks with -p, recognize block size on writing, fix a couple of segfaults. Sep 16, 2007: Fixed return value from archive_write_data() when used with archive_write_disk() to match the documentation and other instances of this same function. Sep 15, 2007: Add archive_entry_link_resolver, archive_entry_strmode Sep 11, 2007: libarchive 2.2.8 released Sep 09, 2007: bsdcpio 0.2 supports most (not yet all) of the old POSIX spec. Sep 01, 2007: libarchive 2.2.7 released Aug 31, 2007: Support for reading mtree files, including an mtree.5 manpage (A little experimental still.) Aug 18, 2007: Read gtar 1.17 --posix --sparse entries. Aug 13, 2007: Refined suid/sgid restore handling; it is no longer an error if suid/sgid bits are dropped when you request perm restore but don't request owner restore. Aug 06, 2007: Use --enable-bsdcpio if you want to try bsdcpio Aug 05, 2007: libarchive 2.2.6 released Aug 05, 2007: New configure option --disable-bsdtar, thanks to Joerg Sonnenberger. Aug 05, 2007: Several bug fixes from FreeBSD CVS repo. Jul 13, 2007: libarchive 2.2.5 released Jul 12, 2007: libarchive 2.2.4 released Jul 12, 2007: Thanks to Colin Percival's help in diagnosing and fixing several critical security bugs. Details available at http://security.freebsd.org/advisories/FreeBSD-SA-07:05.libarchive.asc May 26, 2007: libarchive 2.2.3 released May 26, 2007: Fix memory leaks in ZIP reader and shar writer, add some missing system headers to archive_entry.h, dead code cleanup from Colin Percival, more tests for gzip/bzip2, fix an EOF anomaly in bzip2 decompression. May 12, 2007: libarchive 2.2.2 released May 12, 2007: Fix archive_write_disk permission restore by cloning entry passed into write_header so that permission info is still available at finish_entry time. (archive_read_extract() worked okay because it held onto the passed-in entry, but direct consumers of archive_write_disk would break). This required fixing archive_entry_clone(), which now works and has a reasonably complete test case. May 10, 2007: Skeletal cpio implementation. May 06, 2007: libarchive 2.2.1 released May 06, 2007: Flesh out a lot more of test_entry.c so as to catch problems such as the device node breakage before releasing . May 05, 2007: Fix a bad bug introduced in 2.1.9 that broke device node entries in tar archives. May 03, 2007: Move 'struct stat' out of archive_entry core as well. This removes some portability headaches and fixes a bunch of corner cases that arise when manipulating archives on dissimilar systems. Apr 30, 2007: libarchive 2.1.10 released Apr 31, 2007: Minor code cleanup. Apr 24, 2007: libarchive 2.1.9 released Apr 24, 2007: Fix some recently-introduced problems with libraries (Just let automake handle it and it all works much better.) Finish isolating major()/minor()/makedev() in archive_entry.c. Apr 23, 2007: libarchive 2.1.8 released Apr 23, 2007: Minor fixes found from building on MacOS X Apr 22, 2007: libarchive 2.1.7 released Apr 22, 2007: Eliminated all uses of 'struct stat' from the format readers/writers. This should improve portability; 'struct stat' is now only used in archive_entry and in code that actually touches the disk. Apr 17, 2007: libarchive 2.1.6 released Libarchive now compiles and passes all tests on Interix. Apr 16, 2007: libarchive 2.1.5 released Apr 15, 2007: libarchive 2.1b2 released Apr 15, 2007: New libarchive_internals.3 documentation of internal APIs. Not complete, but should prove helpful. Apr 15, 2007: Experimental "read_compress_program" and "write_compress_program" for using libarchive with external compression. Not yet well tested, and likely has portability issues. Feedback appreciated. Apr 14, 2007: libarchive 2.0.31 released Apr 14, 2007: More fixes for Interix, more 'ar' work Apr 14, 2007: libarchive 2.0.30 released Apr 13, 2007: libarchive now enforces trailing '/' on dirs written to tar archives Apr 11, 2007: libarchive 2.0.29 released Apr 11, 2007: Make it easier to statically configure for different platforms. Apr 11, 2007: Updated config.guess, config.sub, libtool Apr 06, 2007: libarchive 2.0.28 released Apr 06, 2007: 'ar' format read/write support thanks to Kai Wang. Apr 01, 2007: libarchive 2.0.27 released Mar 31, 2007: Several minor fixes from Colin Percival and Joerg Sonnenberger. Mar 12, 2007: libarchive 2.0.25 released Mar 12, 2007: Fix broken --unlink flag. Mar 11, 2007: libarchive 2.0.24 released Mar 10, 2007: Correct an ACL blunder that causes any ACL with an entry that refers to a non-existent user or group to not be restored correctly. The fix both makes the parser more tolerant (so that archives created with the buggy ACLs can be read now) and corrects the ACL formatter. Mar 10, 2007: More work on test portability to Linux. Mar 10, 2007: libarchive 2.0.22 released Mar 10, 2007: Header cleanups; added linux/fs.h, removed some unnecessary headers, added #include guards in bsdtar. If you see any obvious compile failures from this, let me know. Mar 10, 2007: Work on bsdtar test scripts: not yet robust enough to enable as part of "make check", but getting better. Mar 10, 2007: libarchive now returns ARCHIVE_FAILED when a header write fails in a way that only affects this item. Less bad than ARCHIVE_FATAL, but worse than ARCHIVE_WARN. Mar 07, 2007: libarchive 2.0.21 released Mar 07, 2007: Add some ACL tests (only for the system-independent portion of the ACL support for now). Mar 07, 2007: tar's ability to read ACLs off disk got turned off for FreeBSD; re-enable it. (ACL restores and libarchive support for storing/reading ACLs from pax archives was unaffected.) Mar 02, 2007: libarchive 2.0.20 released Mar 2, 2007: It's not perfect, but it's pretty good. Libarchive 2.0 is officially out of beta. Feb 28, 2007: libarchive 2.0b17 released Feb 27, 2007: Make the GID restore checks more robust by checking whether the current user has too few or too many privileges. Feb 26, 2007: libarchive 2.0b15 released Feb 26, 2007: Don't lose symlinks when extracting from ISOs. Thanks to Diego "Flameeyes" Pettenò for telling me about the broken testcase on Gentoo that (finally!) led me to the cause of this long-standing bug. Feb 26, 2007: libarchive 2.0b14 released Feb 26, 2007: Fix a broken test on platforms that lack lchmod(). Feb 25, 2007: libarchive 2.0b13 released Feb 25, 2007: Empty archives were being written as empty files, without a proper end-of-archive marker. Fixed. Feb 23, 2007: libarchive 2.0b12 released Feb 22, 2007: Basic security checks added: _EXTRACT_SECURE_NODOTDOT and _EXTRACT_SECURE_SYMLINK. These checks used to be in bsdtar, but they belong down in libarchive where they can be used by other tools and where they can be better optimized. Feb 11, 2007: libarchive 2.0b11 released Feb 10, 2007: Fixed a bunch of errors in libarchive's handling of EXTRACT_PERM and EXTRACT_OWNER, especially relating to SUID and SGID bits. Jan 31, 2007: libarchive 2.0b9 released Jan 31, 2007: Added read support for "empty" archives as a distinct archive format. Bsdtar uses this to handle, e.g., "touch foo.tar; tar -rf foo.tar" Jan 22, 2007: libarchive 2.0b6 released Jan 22, 2007: archive_write_disk API is now in place. It provides a finer-grained interface than archive_read_extract. In particular, you can use it to create objects on disk without having an archive around (just feed it archive_entry objects describing what you want to create), you can override the uname/gname-to-uid/gid lookups (minitar uses this to avoid getpwXXX() and getgrXXX() bloat). Jan 09, 2007: libarchive 2.0a3 released Jan 9, 2007: archive_extract is now much better; it handles the most common cases with a minimal number of system calls. Some features still need a lot of testing, especially corner cases involving objects that already exist on disk. I expect the next round of API overhaul will simplify building test cases. Jan 9, 2007: a number of fixes thanks to Colin Percival, especially corrections to the skip() framework and handling of large files. Jan 9, 2007: Fixes for large ISOs. The code should correctly handle very large ISOs with entries up to 4G. Thanks to Robert Sciuk for pointing out these issues. Sep 05, 2006: libarchive 1.3.1 released Sep 5, 2006: Bump version to 1.3 for new I/O wrappers. Sep 4, 2006: New memory and FILE read/write wrappers. Sep 4, 2006: libarchive test harness is now minimally functional; it's located a few minor bugs in error-handling logic Aug 17, 2006: libarchive 1.2.54 released Aug 17, 2006: Outline ABI changes for libarchive 2.0; these are protected behind #ifdef's until I think I've found everything that needs to change. Aug 17, 2006: Fix error-handling in archive_read/write_close() They weren't returning any errors before. Aug 17, 2006: Fix recursive-add logic to not trigger if it's not set Fixes a bug adding files when writing archive to pipe or when using archive_write_open() directly. Jul 2006: New "skip" handling improves performance extracting single files from large uncompressed archives. Mar 21, 2006: 1.2.52 released Mar 21, 2006: Fix -p on platforms that don't have platform-specific extended attribute code. Mar 20, 2006: Add NEWS file; fill in some older history from other files. I'll try to keep this file up-to-date from now on. OLDER NEWS SUMMARIES Mar 19, 2006: libarchive 1.2.51 released Mar 18, 2006: Many fixes to extended attribute support, including a redesign of the storage format to simplify debugging. Mar 12, 2006: Remove 'tp' support; it was a fun idea, but not worth spending much time on. Mar 11, 2006: Incorporated Jaakko Heinonen's still-experimental support for extended attributes (Currently Linux-only.). Mar 11, 2006: Reorganized distribution package: There is now one tar.gz file that builds both libarchive and bsdtar. Feb 13, 2006: Minor bug fixes: correctly read cpio device entries, write Pax attribute entry names. Nov 7, 2005: Experimental 'tp' format support in libarchive. Feedback appreciated; this is not enabled by archive_read_support_format_all() yet as I'm not quite content with the format detection heuristics. Nov 7, 2005: Some more portability improvements thanks to Darin Broady, minor bugfixes. Oct 12, 2005: Use GNU libtool to build shared libraries on many systems. Aug 9, 2005: Correctly detect that MacOS X does not have POSIX ACLs. Apr 17, 2005: Kees Zeelenberg has ported libarchive and bsdtar to Windows: http://gnuwin32.sourceforge.net/ Apr 11, 2005: Extended Zip/Zip64 support thanks to Dan Nelson. -L/-h fix from Jaakko Heinonen. Mar 12, 2005: archive_read_extract can now handle very long pathnames (I've tested with pathnames up to 1MB). Mar 12, 2005: Marcus Geiger has written an article about libarchive http://xsnil.antbear.org/2005/02/05/archive-mit-libarchive-verarbeiten/ including examples of using it from Objective-C. His MoinX http://moinx.antbear.org/ desktop Wiki uses libarchive for archiving and restoring Wiki pages. Jan 22, 2005: Preliminary ZIP extraction support, new directory-walking code for bsdtar. Jan 16, 2005: ISO9660 extraction code added; manpage corrections. May 22, 2004: Many gtar-compatible long options have been added; almost all FreeBSD ports extract correctly with bsdtar. May 18, 2004: bsdtar can read Solaris, HP-UX, Unixware, star, gtar, and pdtar archives.

Old cpio archives * store every link with the full body; the onus is on the dearchiver * to detect and properly link the files as they are restored. * "tar" is also pretty simple; it caches a copy the first time it sees * any link. Subsequent appearances are modified to be hardlink * references to the first one without any body. Used by all tar * formats, although the newest tar formats permit the "old cpio" strategy * as well. This strategy is very simple for the dearchiver, * and reasonably straightforward for the archiver. * "new cpio" is trickier. It stores the body only with the last * occurrence. The complication is that we might not * see every link to a particular file in a single session, so * there's no easy way to know when we've seen the last occurrence. * The solution here is to queue one link until we see the next. * At the end of the session, you can enumerate any remaining * entries by calling archive_entry_linkify(NULL) and store those * bodies. If you have a file with three links l1, l2, and l3, * you'll get the following behavior if you see all three links: * linkify(l1) => NULL (the resolver stores l1 internally) * linkify(l2) => l1 (resolver stores l2, you write l1) * linkify(l3) => l2, l3 (all links seen, you can write both). * If you only see l1 and l2, you'll get this behavior: * linkify(l1) => NULL * linkify(l2) => l1 * linkify(NULL) => l2 (at end, you retrieve remaining links) * As the name suggests, this strategy is used by newer cpio variants. * It's noticeably more complex for the archiver, slightly more complex * for the dearchiver than the tar strategy, but makes it straightforward * to restore a file using any link by simply continuing to scan until * you see a link that is stored with a body. In contrast, the tar * strategy requires you to rescan the archive from the beginning to * correctly extract an arbitrary link. */ __LA_DECL struct archive_entry_linkresolver *archive_entry_linkresolver_new(void); __LA_DECL void archive_entry_linkresolver_set_strategy( struct archive_entry_linkresolver *, int /* format_code */); __LA_DECL void archive_entry_linkresolver_free(struct archive_entry_linkresolver *); __LA_DECL void archive_entry_linkify(struct archive_entry_linkresolver *, struct archive_entry **, struct archive_entry **); __LA_DECL struct archive_entry *archive_entry_partial_links( struct archive_entry_linkresolver *res, unsigned int *links); #ifdef __cplusplus } #endif /* This is meaningless outside of this header. */ #undef __LA_DECL #endif /* !ARCHIVE_ENTRY_H_INCLUDED */ Index: head/contrib/libarchive/libarchive/archive_entry_acl.3 =================================================================== --- head/contrib/libarchive/libarchive/archive_entry_acl.3 (revision 309299) +++ head/contrib/libarchive/libarchive/archive_entry_acl.3 (revision 309300) @@ -1,235 +1,246 @@ .\" Copyright (c) 2010 Joerg Sonnenberger .\" All rights reserved. .\" .\" Redistribution and use in source and binary forms, with or without .\" modification, are permitted provided that the following conditions .\" are met: .\" 1.

The ACL interface of .Nm libarchive is derived from the POSIX.1e draft, but restricted to simplify dealing with practical implementations in various Operating Systems and archive formats. .Pp An ACL consists of a number of independent entries. Each entry specifies the permission set as bitmask of basic permissions. Valid permissions are: .Bl -tag -offset indent -compact -width "ARCHIVE_ENTRY_ACL_EXECUTE" .It Dv ARCHIVE_ENTRY_ACL_EXECUTE .It Dv ARCHIVE_ENTRY_ACL_WRITE .It Dv ARCHIVE_ENTRY_ACL_READ .El The permissions correspond to the normal Unix permissions. .Pp The tag specifies the principal to which the permission applies. Valid values are: .Bl -tag -offset indent -compact -width "ARCHIVE_ENTRY_ACL_GROUP_OBJ" .It Dv ARCHIVE_ENTRY_ACL_USER The user specified by the name field. .It Dv ARCHIVE_ENTRY_ACL_USER_OBJ The owner of the file. .It Dv ARCHIVE_ENTRY_ACL_GROUP The group specied by the name field. .It Dv ARCHIVE_ENTRY_ACL_GROUP_OBJ The group who owns the file. .It Dv ARCHIVE_ENTRY_ACL_MASK The maximum permissions to be obtained via group permissions. .It Dv ARCHIVE_ENTRY_ACL_OTHER Any principal who doesn't have a user or group entry. .El The principals .Dv ARCHIVE_ENTRY_ACL_USER_OBJ , .Dv ARCHIVE_ENTRY_ACL_GROUP_OBJ and .Dv ARCHIVE_ENTRY_ACL_OTHER are equivalent to user, group and other in the classic Unix permission model and specify non-extended ACL entries. .Pp All files have an access ACL .Pq Dv ARCHIVE_ENTRY_ACL_TYPE_ACCESS . This specifies the permissions required for access to the file itself. Directories have an additional ACL .Pq Dv ARCHIVE_ENTRY_ACL_TYPE_DEFAULT , which controls the initial access ACL for newly created directory entries. .Pp .Fn archive_entry_acl_add_entry and .Fn archive_entry_acl_add_entry_w add a single ACL entry. For the access ACL and non-extended principals, the classic Unix permissions are updated. .Pp .Fn archive_entry_acl_clear removes all ACL entries and resets the enumeration pointer. .Pp .Fn archive_entry_acl_count counts the ACL entries that have the given type mask. .Fa type can be the bitwise-or of .Dv ARCHIVE_ENTRY_ACL_TYPE_ACCESS and .Dv ARCHIVE_ENTRY_ACL_TYPE_DEFAULT . If .Dv ARCHIVE_ENTRY_ACL_TYPE_ACCESS is included and at least one extended ACL entry is found, the three non-extened ACLs are added. .Pp .Fn archive_entry_acl_next and .Fn archive_entry_acl_next_w return the next entry of the ACL list. This functions may only be called after .Fn archive_entry_acl_reset has indicated the presence of extended ACL entries. .Pp .Fn archive_entry_acl_reset prepare reading the list of ACL entries with .Fn archive_entry_acl_next or .Fn archive_entry_acl_next_w . The function returns either 0, if no non-extended ACLs are found. In this case, the access permissions should be obtained by .Xr archive_entry_mode 3 or set using .Xr chmod 2 . Otherwise, the function returns the same value as .Fn archive_entry_acl_count . .Pp .Fn archive_entry_acl_text_w converts the ACL entries for the given type mask into a wide string. In addition to the normal type flags, .Dv ARCHIVE_ENTRY_ACL_STYLE_EXTRA_ID and .Dv ARCHIVE_ENTRY_ACL_STYLE_MARK_DEFAULT can be specified to further customize the result. The returned long string is valid until the next call to .Fn archive_entry_acl_clear , .Fn archive_entry_acl_add_entry , .Fn archive_entry_acl_add_entry_w or .Fn archive_entry_acl_text_w . +.Pp +.Fn archive_entry_acl_types +get ACL entry types contained in an archive entry's ACL. As POSIX.1e and NFSv4 +ACL entries cannot be mixed, this function is a very efficient way to detect if +an ACL already contains POSIX.1e or NFSv4 ACL entries. .Sh RETURN VALUES .Fn archive_entry_acl_count and .Fn archive_entry_acl_reset returns the number of ACL entries that match the given type mask. If the type mask includes .Dv ARCHIVE_ENTRY_ACL_TYPE_ACCESS and at least one extended ACL entry exists, the three classic Unix permissions are counted. .Pp .Fn archive_entry_acl_next and .Fn archive_entry_acl_next_w return .Dv ARCHIVE_OK on success, .Dv ARCHIVE_EOF if no more ACL entries exist and .Dv ARCHIVE_WARN if .Fn archive_entry_acl_reset has not been called first. .Pp .Fn archive_entry_text_w returns a wide string representation of the ACL entrise matching the given type mask. The returned long string is valid until the next call to .Fn archive_entry_acl_clear , .Fn archive_entry_acl_add_entry , .Fn archive_entry_acl_add_entry_w or .Fn archive_entry_acl_text_w . +.Pp +.Fn archive_entry_acl_types +returns a bitmask of ACL entry types or 0 if archive entry has no ACL entries. .Sh SEE ALSO .Xr archive_entry 3 .Xr libarchive 3 , .Sh BUGS .Dv ARCHIVE_ENTRY_ACL_STYLE_EXTRA_ID and .Dv ARCHIVE_ENTRY_ACL_STYLE_MARK_DEFAULT are not documented.
