touch: Allow setting the timestamp to -1.

2024-04-04T09:43:12Z

Note that VFS internally interprets a timestamp of -1 as “do not set”, so this has no effect, but at least touch won't incorrectly reject the given date / time (1969-12-31 23:59:59 UTC) as invalid. While here, fix some style issues.

touch: don't leak descriptor if fstat(2) fails

2022-03-12T10:38:12Z

If fstat(2) fails the close(2) won't be called, which will leak the file descriptor. The idea was borrowed from OpenBSD, where similar patch was applied for futimens(2). MFC after: 1 week

touch.1: Update to conform to POSIX 2004

2018-06-01T22:34:59Z

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.

General further adoption of SPDX licensing ID tags.

2017-11-20T19:49:47Z

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.

Renumber copyright clause 4

2017-02-28T23:42:47Z

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. Submitted by: Jan Schaumann Pull Request: https://github.com/freebsd/freebsd/pull/96
