* tar: expose ARCHIVE_READDISK_NO_SPARSE as --no-read-sparseJonas Witschel2021-11-141-0/+4

* Introduce archive_write_disk(3) flag ARCHIVE_EXTRACT_SAFE_WRITESzoulasc2020-01-201-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | This flag changes the way that regular files are extracted: Instead of removing existing files first and re-creating them in order to replace their contents, a temporary file is created and when writing to the temporary file is completed, the file is rename(2)d to the final destination name. This has the effect of presenting a consistent view of the file to the system (either the file with the new contents or the file with the old contents). Removing and overwriting the file has the undesired side effect that the the system can either not see the file at all (from the time it is being removed till the time it is being re-created), or worse it can see partial file contents. This is problematic when extracting system files (for example shared libraries). If the existing file that is going to be overwritten is a hard link, for now we unlink it before calling rename(2). This can be done correctly by creating a hardlink to a tmpnam(3) generated file and then use rename(2), but that is fairly intrusive and requires refactoring. Fixes #1289

* Issue #131: Implement tar --no-xattrTim Kientzle2015-01-101-0/+1
| | | | | | | | | This option suppresses both archiving and restoring xattrs. The latter relies on existing machinery; for the former, I've added a ARCHIVE_READDISK_NO_XATTR flag to archive_read_disk. Caveat: I've not implemented any tests for these new features.

* Add --ignore-zeros option to bsdtarKevin Locke2014-01-141-0/+2
| | | | | | | This option is an alias for --options read_concatenated_archive introduced for compatibility with GNU tar. Signed-off-by: Kevin Locke <kevin@kevinlocke.name>
* Support POSIX regular expression support using PCRE in CMake builds.Andres Mejia2013-01-311-1/+1
| | | | | | | This change is mainly meant for Windows regex support, where PCRE Windows development is much more active than development of the regex library found in the GNUWin32 packages. I found that the latest release of PCRE built right out of the box, unlike the GNUWin32 regex library released 6 years ago which failed to build from source for me using the mingw toolchain.

* Extend the tar test to verify that symlink and hardlinkTim Kientzle2011-09-041-1/+1
| | | | | | | | | | targets get properly rewritten by default. Adjust the -s parser so that symlink and hardlink target rewriting is enabled by default and the 's' or 'S' flags disable both. SVN-Revision: 3676

* Work around broken PSXCRT unistd.h, which defines macrosTim Kientzle2011-02-131-1/+1
| | | | | | that break any usage of names "optarg" or "option". SVN-Revision: 2979
* Support --numeric-owner for tar extraction as well as archive creation.Tim Kientzle2010-12-311-0/+1
| | | | | | | | | | This just involves reworking tar's extraction routines slightly to use archive_read_extract2() with a custom-configured archive_write_disk object, instead of the more convenient archive_read_extract() interface that automatically builds a standard archive_write_disk object. SVN-Revision: 2849
* Choose the copy buffer size used for reading filesTim Kientzle2010-06-261-0/+1
| | | | | | | | | | | to be archived dynamically: * At least 64k * At least as large as the -b setting In particular, this should speed up things noticably when large -b values are in use. This is also the first cut at aligning the copy buffer so we can take advantage of O_DIRECT someday. SVN-Revision: 2504
* Use -b setting when interpolating archives.Tim Kientzle2010-06-261-0/+1
| | | | | | | | Simplify the handling of -b values by setting a default early and then just using the value instead of duplicating the logic. SVN-Revision: 2503
* Add lzip write filter and --lzip option to bsdtar.Michihiro NAKAJIMA2010-05-051-0/+1
| | | | SVN-Revision: 2373
* Add --gid, --gname, --uid, --uname options to tar.Tim Kientzle2010-05-011-2/+9
| | | | | | | | | | | These allow you to override the user/group information both when creating an archive and when restoring an archive. I've also reimplemented --numeric-owner to be a synonym for --gname="" --uname="". Still needs tests... SVN-Revision: 2349

* First step towards integrating Mac OS "copyfile" extension from Apple.Tim Kientzle2010-02-011-0/+2
| | | | | | | This part adds probes for the copyfile.h header, and adds a new command-line option --disable-copyfile, which does nothing on non-MacOS systems. SVN-Revision: 1852
* Trying to figure out what printf modifiers to use on what platforms toTim Kientzle2009-10-311-0/+1
| | | | | | | display 64-bit values is getting to be real PITA. Just roll our own conversion and use that. SVN-Revision: 1562
* Overhaul the SIGINFO/SIGUSR1 reporting. This is a littleTim Kientzle2009-07-161-6/+1
| | | | | | | | simpler and gives a lot more information. In particular, it reports total bytes in/out, total files and compression ratio, in addition to reporting the current file being processed. SVN-Revision: 1223
