   Avoid acl_ prefix for functions
   The acl.h header from libacl uses acl_ prefix for its functions. Avoid
   defining functions with the same name in order to protect its namespace.

   Comments

   Assume directory members have size=0.
   Since commit b8d8a61b, tar started honoring size field in headers
   of the directory archive members when listing and extracting. That
   doesn't seem right: although GNU tar always stores 0 for such members,
   there are other tar implementation that don't. As a result, GNU tar
   skips the actual directory contents when listing or extracting archives
   created by such implementations.
   
   This commit fixes that by assuming that size is 0 for directory archive
   members.
   
   * src/list.c (member_is_dir): Restore function.

   Draft patch for openat2 changes vs --one-top-level
   The patch leverages the existing -C code. In order to do that, every
   entry in the wd[] table gets another companion entry in the table that
   represents the --one-top-level directory. There is one additional field
   in each entry that allows skipping the companion entries if they are not
   desired.
   
   The actual directory is created lazily by chdir_do() if needed, as you
   requested, to avoid empty "a/foo" after --one-top-level=foo -C a -C b.
   
   The patch "by the way" fixes also extraction of hardlinks with
   --one-top-level which currently is broken in the typical case (the
   transform is not applied to the target, so the hardlink is wrong).
   
   The patch does not yet handle the --show-transformed case with
   --one-top-level that you discussed in another subthread. As a result, two
   tests now fail (onetop02.at and onetop04.at). I suppose that this would
   be quite easy to fix.
   
   Another issue that I am aware of is that I am not sure whether to call
   repair_delayed_set_stat and/or delay_set_stat on the newly created
   directories like extract_dir() does (the whole delay_set code is abit
   mysterious to me).
   
   Use of --create together with --one-top-level should probably be
   forbidden, as unlink.c uses wd[] in a way that will likely break in the
   presence of companion entries (the chdir_do call in
   flush_deferred_unlinks).
   
   Show the one-top-level arg as a transformation

    Comments

    Get rid of create_dir
    It turns out that make_directories can do what we need (create all
    directories in a path) if we append a dummy "." component, as it creates
    directories up to and excluding the last component of the path.
    
    Also, do not avoid using delay_set_stat on the newly created
    directories. This matches the rest of the code and avoids potentially
    leaving the newly-created directories with too open permissions.
    This requires some workarounds to cope with
    apply_nonancestor_delayed_set_stat and mark_metadata_set problems: do it
    as in the rest of the code - apply the stats before proceeding with
    extraction of anything else.

    Use faccessat instead of fstatat, to avoid EOVERFLOW issues.

    tar: open directories more efficiently
    Without this patch, tar would open the parent of a directory
    for search, then open the directory itself for search.
    It's more efficient to just open the directory for search.
    * src/create.c (create_archive, restore_parent_fd, chdir_do):
    Use open_searchdir instead of opening by hand.
    * src/misc.c (chdir_do): Use fdbase_opendir and fdbase_close
    instead of openat and close, so that the fd is cached properly.
    (chdirable): New function.
    (fdbase_clear): Use it to avoid closing chdirable FDs.
    (fdbase_close): New function.
    (open_subdir): New arg OFLAGS.  All callers changed.
    (fdbase_opendir): New arg CHILD_OFLAGS.  All callers changed.
    Prefer AT_FDCWD for absolute file names, so that we need not
    worry about chdir_fd == BADFD in that case.
    Do not allow empty file names.
    When replacing an old directory, do not close its fd if it
    is chdirable.
    (open_searchdir): New function.
    * src/tar.c (decode_options): Do not worry about one_top_level_dir
    and IS_ABSOLUTE_FILE_NAME (one_top_level_dir), as fdbase_opendir
    now prefers AT_FDCWD for absolute file names.
    (tar_stat_close): Use fdbase_close instead of close,
    so that the fd is cached properly.

    tar: reuse FD when extracting hard links
    * src/extract.c (rename_directory): Redo to accommodate
    new semantics of fdbase1, and to use fds more intelligently.
    * src/misc.c (fdbase_opendir): If ALTERNATE, it is now OK to use,
    though not update, the main cache.  This makes it possible for the
    caller to do linkat (N, "A", N, "B") instead of the
    linkat (N, "A", N + 1, "B") it previously did, and this
    saves some open and close calls on directories.

    tar: invalidate directory cache after failed open
    fdbase_opendir copies a requested directory name into the cache before
    opening it.  If open_subdir fails, this leaves the new name associated
    with the old file descriptor.  A retry after tar creates the missing
    parent can then extract into the old directory.
    
    Close an unowned old descriptor before trying to open the new dir and
    invalidate the cache entry if that fails.  Add a regression test using
    equal-length sibling directory names.
    
    * src/misc.c (fdbase_opendir): Invalidate the cache after a failed
    replacement open.
    * tests/extrac35.at: New test.

    Accept relative file names in recursive exclude files.
    This fixes bug #68616: exclude lists supplied with
    --exclude-ignore-recursive now specify file names irrespective
    of the actual name of the containing directory. This also fixes
    processing of the VCS ignore files.
    
    * src/exclist.c (struct exclist): New fields: prefix, prefix_len.
    (info_attach_exclist): Store original directory name as prefix.
    (info_free_exclist): Free prefix.
    (excluded_name): Recompute rname at each loop stripping off the
    directory prefix.

    * tests/exclude22.at: New test.
    * tests/Makefile.am: Add new tests.

    tar: don’t evict from fdbase_cache if open fails
    * src/misc.c (fdbase_opendir): Fix the recent fix
    d1df7f403de05bfbe11527a5b570469fb1011fda,
    which introduced bugs causing us to pass BADFD to openat.
    Don’t close and evict an existing cache resident merely because
    the open of a subdirectory fails.
    Refactor this too-tricky code to add some clarity.

    tar: refactor fdbase_opendir
    * src/misc.c (fdbase_opendir): Rename locals to more clearly
    distinguish new subdirectory name from old.
    Cache c->subdir and c->subdirlen to help the compiler warn
    us statically if we mess up.
    Move the large part of an if that ends in a break to be
    out of the loop, to make things a bit clearer and reduce indentation.
    Distinguish whether the new name is a subdirectory of the old,
    from whether the new name extends the old; they are not the same
    thing as the new and old names can have different chdir_fd values.
    If the new name extends the old, don’t overwrite the old name;
    just store into the old name’s extension.
    Although these changes improve performance with long names,
    the primary goal is to clarify the code, not performance.

    tar: support --one-top-dir=/abs/olute
    It appears that people were using the --one-top-dir=DIR option
    with an absolute file name, even though this behavior was
    undocumented and erratic and recent tar versions rejected it.
    Document and implement behavior that I hope people expect.
    * src/extract.c (MAKEDIR_FULL_ESCAPE): New constant.
    (make_directories): Let full directory names escape if
    MAKEDIR_FULL_ESCAPE is passed.
    (create_dir): Let DIR escape if it is the one-top-level dir
    or an ancestor.
    * src/misc.c (fdbase_opendir): Replace old CHILD_OFLAGS arg with
    two new args CHILD and OFLAG, so that the functionalities can be
    distinguished.  All callers changed.
    (fdbase_escape): New function.
    (fdbase): Use it, for simplicity.
    * tests/onetop06.at: New test file.
    * tests/Makefile.am (TESTSUITE_AT): Add it.
    * tests/testsuite.at: Include it.

    tar: reject -C x --one-top-dir=/abs/olute
    It’s not clear what ‘-C x --one-top-dir=/abs/olute’ should mean,
    so for now let’s play it safe and reject that combination.
    * src/misc.c (chdir_arg): Diagnose attempts to combine
    -C with --one-top-level=/abs/olute.
    * tests/onetop06.at: Move last test to onetop07.at,
    since it now differs in behavior and it’s better to
    test it separately.
    * tests/onetop07.at: New file.
    * tests/Makefile.am (TESTSUITE_AT): Add it.
    * tests/testsuite.at: Include it.

    tar: more-consistent EOF checking
    * src/names.c (read_name_from_file): Test sign of getc return,
