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.

Don't kill pid -1 on overflow from strtol(3).

Store the result in a proper long and then compare to the proper pid_t for overflow, so that no MD assumptions are made. Reviewed by: jilles MFC after: 2 weeks Differential Revision: https://reviews.freebsd.org/D9887

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

sh: Allow kill %job on jobs started without job control.

2014-03-15T14:58:48Z

When killing a %job started without job control, kill all processes in it. As with process groups and zombies, if any process in the job can be killed or has already terminated, the command is successful. This also fixes occasional failures of the builtins/kill1.0 test.

sh: Successfully do nothing when killing a terminated job.

2014-03-08T19:44:34Z

If a job has terminated but is still known, silently do nothing when using the kill builtin with the job specifier. Formerly, the shell called kill() with the process group ID that might have been reused.

Remove cast that was only required for K&R C.

Make sys_signame upper case.

2011-02-04T16:40:50Z

This matches the constants from with 'SIG' removed, which POSIX requires kill and trap to accept and 'kill -l' to write. 'kill -l', 'trap', 'trap -l' output is now upper case. In Turkish locales, signal names with an upper case 'I' are now accepted, while signal names with a lower case 'i' are no longer accepted, and the output of 'killall -l' now contains proper capital 'I' without dot instead of a dotted capital 'I'.

sh: Add kill builtin.

2010-12-21T22:47:34Z

This allows specifying a %job (which is equivalent to the corresponding process group). Additionally, it improves reliability of kill from sh in high-load situations and ensures "kill" finds the correct utility regardless of PATH, as required by POSIX (unless the undocumented %builtin mechanism is used). Side effect: fatal errors (any error other than kill(2) failure) now return exit status 2 instead of 1. (This is consistent with other sh builtins, but not in NetBSD.)
