<string.h>, <stdlib.h>, <stdbool.h>, <limits.h>, <errno.h>.
Include "system.h" before the other lib/*.h header files.
Include <sys/types.h> before "system.h".
(wrap_write): Remove declaration of unused local, initial_column.
(main): Prefer dirent.d_ino to stat when possible.
(gobble_file): Add inode argument.
(print_dir): Pass inode if available.
(usage): Remove inaccuracy.
(interactive_type): New enum.
(long_opts): Let interactive take an optional argument.
(interactive_args, interactive_types): New option arguments.
(usage): Document -I, --interactive=WHEN. Use program_name
instead of a basename.
(main): New -I option, new behavior to --interactive.
[From Eric Blake]
(close_preserve_errno): New function.
(fd_to_subdirp): Don't print a diagnostic in this function.
Do it from the callers instead, unless rmdir succeeds.
(remove_cwd_entries, remove_dir): Adjust callers.
the same directory more than once in the hierarchy beneath a single
command-line argument. That is legitimate, e.g. when there are
two or more symbolic links, each pointing to some directory that
would not otherwise be copied. Reported by Christophe LYON.
to put a regular file in O_NONBLOCK mode fails with EPERM.
That happens on Linux when using tail -f on a file with the
append-only attribute. Reported by Dean Gaudet. For details,
see http://savannah.gnu.org/bugs/?func=detailitem&item_id=15473.
Don't include "lchown.h".
(restricted_chown): Accept a new parameter, CWD_FD, and use it in
calling openat, lchownat, chownat, rather than open, lchown, chown.
Update caller.
its clients accordingly -- note that du.c uses fts but doesn't need
any adjustment, since it doesn't operate on the actual files,
but rather just uses the stat buffers provided by fts.
Include "openat.h".
(process_file): Use chmodat (fts->fts_cwd_fd,... in place of chmod (...
cast its result to void, to avoid gcc's warning that
``left-hand operand of comma expression has no effect''.
(DECIMAL_DIGIT_ACCUMULATE, X2REALLOC): Likewise.
First off, the attribute should have been `volatile' (not static)
to avoid longjmp-related risk of clobber. Secondly, now there is
no longer any risk of a local variable being clobbered, so there's
no need for any attribute at all.
(AD_pop_and_chdir): Use gotos to avoid some duplication.
(AD_push): Rewrite an assertion so that the entire computation
goes away when assertions are turned off.
(restricted_chown): Return it, if the file cannot be accessed due
to EPERM, or if no uid or gid are required, or if the file is
neither a directory nor a regular file. Rewrite to avoid gotos.
(change_file_owner): Handle RC_do_ordinary_chown case.
Rewrite to avoid gotos.
