* | libarchive: allow extraction of hard linksRon Yorston2021-01-191-7/+0
| | | | | | | | | | | | | | | | Allow create_or_remember_link() to create hardlinks. As a result tar and cpio can now extract hard links. Since unzip only supports symlinks it sees no improvement. As before, attempts to extract symlinks result in a warning.

| | | | | | | | | | | | | | | | Recent upstream changes made the failure of symlink(2) when extracting from an archive a fatal error. The busybox-w32 implementation of symlink(2) always fails. Just issue a warning and move on.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This mostly reverts commit bc9bbeb2b81001e8731cd2ae501c8fccc8d87cc7 "libarchive: do not extract unsafe symlinks unless $EXTRACT_UNSAFE_SYMLINKS=1" Users report that it is somewhat too restrictive. See https://bugs.busybox.net/show_bug.cgi?id=8411 In particular, this interferes with unpacking of busybox-based filesystems with links like "sbin/applet" -> "../bin/busybox". The change is made smaller by deleting ARCHIVE_EXTRACT_QUIET flag - it is unused since 2010, and removing conditionals on it allows commonalizing some error message codes. function old new delta create_or_remember_symlink - 94 +94 create_symlinks_from_list - 64 +64 tar_main 1002 1006 +4 unzip_main 2732 2724 -8 data_extract_all 984 891 -93 unsafe_symlink_target 147 - -147 ------------------------------------------------------------------------------ (add/remove: 2/1 grow/shrink: 1/2 up/down: 162/-248) Total: -86 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* | Enable seamless compression for WIN32Ron Yorston2015-05-271-0/+10
|/ | | | | | | | | | | | | | | | In the archival code we pretend that WIN32 is a no-MMU platform and use the new mingw_popen_fd routine to pipe data to/from commands to compress/decompress. The pretence is maintained by redefining MMU macros in bb_archive.h. This is mostly used in the archival code but there are a handful of places where it's used to access public interfaces. The symbol BB_ARCHIVE_PUBLIC is defined in these places. With these changes: tar supports seamless compression/decompression rpm2cpio and dpkg-deb can be enabled
