Remove lots of #if directives involving FLASK_LINUX
[!FLASK_LINUX] (is_flask_enabled): Define.
(stat_secure, lstat_secure): Define.
(print_statfs): Remove lots of nested #if directives.
Instead, rely on support fo %llu and %lld printf formats --
but that is only temporary, since it's not porable enough.
(main): Hoist is_flask_enabled test to be done here, rather
than in each of do_stat and do_statfs for every argument.
[HAVE_SYS_SYSMACROS_H]: Guard inclusion of sys/sysmacros.h.
(PROGRAM_NAME, AUTHORS): Define.
(long_options): Declare/define.
(print_human_access): Rewrite to use mode_string.
(usage): Rewrite.
(main): Use getopt_long.
[long_opts]: Remove.
(usage): Tweak --help output; use *_OPTION_DESCRIPTION macros.
(main): Don't use getopt directly. Use parse_long_options instead.
Tweak a diagnostic.
Use EXIT_FAILURE rather than a literal `1'.
(main): If POSIXLY_CORRECT is set, don't recognize --help or --version,
so the program can operate on a file with one of those names.
[long_opts]: Remove.
(usage): Tweak --help output; use *_OPTION_DESCRIPTION macros.
(main): Don't use getopt directly. Use parse_long_options instead.
Tweak a diagnostic.
Use EXIT_FAILURE rather than a literal `1'.
down to just before the first use of that variable. Otherwise, it was
possible to make mv (and probably cp, too) malfunction when copying
hard-linked files into a directory containing at least one of the
source file names. Call forget_created everywhere thereafter where
this function returns without creating a destination file that might
subsequently be linked. Reported by Iida Yosiaki.
Might as well keep it simple, and like bash.
(binary_operator): Fix bug with -nt and -ot, when one of the
files did not exist. We want to be compatible with the ksh93
documentation, and with Bash.
(using errno from the failed unlink) when a cross-device `mv'
fails, e.g., because the destination cannot be unlinked.
Prompted by a report from Karl Berry.
removing unintended files. In one scenario, if root is removing a
hierarchy that is writable by the malicious user, that user may trick
root into removing all of `/'. Reported by Wojciech Purczynski.
(remove_dir): After chdir `..', call lstat to get the
dev/inode of "." and fail if they aren't the same as the old numbers.
(remove_cwd_entries): New parameter, `cwd_dev_ino'.
(remove_dir): Likewise.
(rm): Likewise.
Adjust all callers.
(long_opts): Add --copy-contents.
(usage): Describe new behavior. Sort options.
(main): Implement new behavior. Remove diagnostics for -a and -r;
no longer needed.
whereby an unprivileged user could gain read access to otherwise-
inaccessible files when root uses cp or mv to copy a hierarchy
belonging to that user.
(strftime, time, stime): Remove declarations; no longer needed.
(usage): Document %N.
(main): Use gettime rather than time to get the time of day,
so that we can get fractional times.
Similarly for settime and stime, so that we can set fractional times
(though this currently is not available to the user since we don't
parse fractional times; add FIXMES for that).
Check for gettime failures; e.g. this can occur if it
is past 2038 and we are a 32-bit app running on a 64-bit OS.
Get fractional part of file time stamps.
Do not falsely report failures just because time_t happens to be -1
(e.g. a file time stamp 1 second before the epoch).
(show_date): 2nd arg is now struct timespec, not time_t.
All uses changed. Use nstrftime rather than strftime, so that
we can format fractional seconds.
