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

2022-03-19T13:16:29Z

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 (cherry picked from commit cb54c500d0e1a2c52270b15c6db6a88ca3feb86a)

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

Add META_MODE support.

2015-06-13T19:20:56Z

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. Differential Revision: D2796 Reviewed by: brooks imp

touch: Fix some subtle bugs related to NULL times fallback:

2015-02-15T21:28:00Z

* 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. Reviewed by: bde
