* Fix invalid use of macros and two typosMateusz Piotrowski2020-04-241-4/+4
| | | | | | | | | | | | It turns out that currently mandoc(1) is not handling Fl in Ss correctly (maybe it never was). Let's just replace "Fl S \&Ss ..." with "-S ...". After all, this subsection title is stylized anyway, so Fl is not that helpful. MFC after: 2 weeks Notes: svn path=/head/; revision=360283
* env(1): grow -L user/class and -U user/class optionsKyle Evans2020-02-053-5/+100
| | | | | | | | | | | | | | | This allows one to set the environment of the specified user either from login.conf alone (-L) or both login.conf and ~/.login_conf if present (-U). This is a supporting feature to allow service(8) to pull in the environment of the "daemon" class before invoking the rc script. This is a part of D21481.

* various: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-272-0/+4
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. 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. No functional change intended.

* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-1/+3
| | | | | | | | | | | | | | | | | 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.

My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

* Significantly reduce the memory leak as noted in BUGS section forSean Farley2007-07-041-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | setenv(3) by tracking the size of the memory allocated instead of using strlen() on the current value. Convert all calls to POSIX from historic BSD API: - unsetenv returns an int. - putenv takes a char * instead of const char *. - putenv no longer makes a copy of the input string. - errno is set appropriately for POSIX. Exceptions involve bad environ variable and internal initialization code. These both set errno to EFAULT. Several patches to base utilities to handle the POSIX changes from Andrey Chernov's previous commit. A few I re-wrote to use setenv() instead of putenv(). New regression module for tools/regression/environ to test these functions. It also can be used to test the performance. Bump __FreeBSD_version to 700050 due to API change.

This can be used to provide all the flexibility (and more!) that was lost by recent changes to how the kernel parses #!-lines in shell scripts. The '-P' option provides a way to specify an alternate set of directories to use when searching for the 'utility' program to run. This way you can be sure what directories are used for that search, without changing the value of PATH that the user has set. Note that on FreeBSD 6.0, this option is worthless unless the '-S' option is also used. Approved by: re (blanket `env') Notes: svn path=/head/; revision=147493
