2a1fb74048 touch.1: Update to conform to POSIX 2004
POSIX borrowed the "double leap second" bug from C89.  Double leap seconds can
never happen.  This mistake was present in at least POSIX 1997 and fixed by
POSIX 2004.  I can't find a copy of 2001 online to determine if the bug was
present in that revision.

While here, remove duplicate language between -d and -t.  A few other minor
enhancements and an igor (lint) bugfix.

Further reading:

8a16b7a18f General further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

fbbd9655e5 Renumber copyright clause 4
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

ccfb965433 Add META_MODE support.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

33df3caae6 touch(1): Xref utimensat(2) instead of utimes(2). 2015-03-08 22:49:34 +00:00
Jilles Tjoelker
51492908f9 touch: Fix some subtle bugs related to NULL times fallback:
* Do not subvert vfs.timestamp_precision by reading the time and passing
  that to utimensat(). Instead, pass UTIME_NOW. A fallback to a NULL times
  pointer is no longer used.

* Do not ignore -a/-m if the user has write access but does not own the
  file. Leave timestamps unchanged using UTIME_OMIT and do not fall back to
  a NULL times pointer (which would set both timestamps) if that fails.

587714504f touch: Add the -d option from POSIX.1-2008.
This is much like -t but with a different format which is ISO8601-like and
allows fractions of a second.

The precision is limited to microseconds because of utimes() and friends,
even though stat() returns nanoseconds.

401c9fda42 Remove useless and potentially dangerous rw() function which tries to
update access and modification times by reading and writing the file.
chmod(2) in rw() doesn't help because utimes(2) allow owner and the
super-user to change times. Using just utimes(2) should be sufficient.

The -f option becomes no-op.

c64b097bfc - If lstat()/stat() fails with an error other than ENOENT, don't ignore
the error and assume that the file doesn't exist. Touch could return
  success with -c option even if the file existed and time was not set.
- If the first utimes_f() call fails with -A option, give up and don't
  continue trying to set times to current time. [1]
- Set exit status to 1 when setting of timestamps fails for a directory
  or symbolic link even though lstat()/stat() would succeed.
- Don't print bogus error message when rw() succeeds.

track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

     .\"    $Id$
     .\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.
