	bin/mkdir/mkdir.c: revision 1.39

PR bin/56398

The final component of both a/b/c and a/b/c/ is "c", so that's the one
to which the -m arg applies.

Ooops, restore accidently removed files from merge mishap

Sync with HEAD

static + __dead

Sync with wrstuden-revivesa-base-2.

Remove the \n and tabs from the __COPYRIGHT() strings.

Fix setmode error handling.

remove unused code left from printescaped() backput as pointed out by Jeff
Ito in PR bin/23969 and PR bin/23970.

Following private discussion with kleink@ and hubertf@ and public discussion
on tech-userlevel@, back out printescaped() functionality.
kleink: ``We sell rope.''

Comment out unneeded code now that the kernel has been fixed to ignore
trailing slashes.

use bounded string op

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22249, verified by myself.

As discusses a little while back on tech-userlevel:

If stdout is a tty, use vis(3) to print any filenames to prevent garbage
from being printed if the filename contains control- or other non-printable
characters.

While here, sprinkle some EXIT_FAILURE and NOTREACHED where appropriate.

Fix typo in mkpath()'s test before chmod().
Noted in [bin/20652] by Anthony Mallet.

Rework -p support again;
- If mkdir() fails on a component (no matter what the error is),
  stat() the result.  If the stat() fails, print the error mkdir() generated.
  Otherwise, if the result is not a directory, explicitly fail with ENOTDIR.
- Move the chmod() of last element to be done only if the mkdir() succeeded
  (i.e, it wasn't an existing directory)

Fixes problem introduced in previous commit where "mkdir -p existing"
on a read-only file system would incorrectly return a non zero exit code,
whilst retaining the race-condition fix of the previous commit.

Thanks to simonb@ for sanity checking my fix versus the standards.

in mkpath(), don't try to stat() the to-be-created directory beforehand,
just try to create it and interpret any error appropriately.
this fixes a problem where multiple "mkdir -p" processes can race,
with the loser returning a spurious error.

Cosmetic changes.

ANSIfy, KNF, use [gs]etprogname. By Petri Koistinen.

- The type of return value of setmode is a void * and getmode takes it,
  rather than mode_t *.
- Free the storage allocated by setmode unless it is obvious that program
  exits immediately.

Change previous to use symbolic names for file modes.  Also, clean up some
whitespace lossage and use EXIT_{SUCCESS,FAILURE}.

Only call chmod(2) if we create a directory with a mode which isn't
accepted by mkdir(2).

Insert a missing 'else' which caused mknod(2) to still be called
even if mkdir(2) failed. At best this caused two (different)
error messages to be printed. At worst, it changed the mode of
an existing file/directory.

umask()/mkdir() system calls will not set the setuid bit; the kernel intentionally
  discards the high bits, so "mkdir -m 1777 foo" won't set the sticky bit. So call
  chmod() on the directory.

Delint.

lint

Fix compiler warnings
Add WARNS=1

kill use of register

Fix mkdir -p to not ignore terminal directory mode specified.
Closes pr bin/2686.

Style and format police.

Don't complain if a directory already exists.  From Greg Hudson, but
slightly edited.

clean up slightly; id tags, alphabetization, prototypes, etc.

Revert to code before it was merged with 4.4lite.
Updated to conform to new NetBSD RCS ID conventions.

Merge 4.4-Lite version.

Import original 4.4-Lite version.

Strip trailing slashes, to make "mkdir -p" work as specified by POSIX.2.

simplify recursive directory create (mkdir -p) code

Localization changes.
Updated to use standard error message routines.

#include <unistd.h>, so getopt(), optarg, opterr, optind, and optopt
declarations can be removed from <stdlib.h>.

Add RCS identifiers.

Make Posix 1003.2 (D11.2) compliant by adding -m (mode) option.

changed "Id" to "Header" for rcsids

added rcs ids to all files

initial import of 386bsd-0.1 sources
