Alan Somers 6040822c4e Make timespecadd(3) and friends public
The timespecadd(3) family of macros were imported from NetBSD back in
r35029. However, they were initially guarded by #ifdef _KERNEL. In the
meantime, we have grown at least 28 syscalls that use timespecs in some
way, leading many programs both inside and outside of the base system to
redefine those macros. It's better just to make the definitions public.

Our kernel currently defines two-argument versions of timespecadd and
timespecsub.  NetBSD, OpenBSD, and FreeDesktop.org's libbsd, however, define
three-argument versions.  Solaris also defines a three-argument version, but
only in its kernel.  This revision changes our definition to match the
common three-argument version.

Bump _FreeBSD_version due to the breaking KPI change.

$FreeBSD$

This directory is for regression test programs.

A regression test program is one that will exercise a particular bit of the
system to check that we have not reintroduced an old bug.

Tests should be implemented in files with a .t extension.  Each .t file
can contain more than one test, and can be implemented in any scripting
language -- /bin/sh, Perl...

The test protocol is quite simple.  At its most basic, each .t file should, 
when run, print a line in this format:

   1..m

where m is the number of tests that will be run.

Each test should produce a single line of output.  This line should start
with one of

   ok n
   not ok n

to indicate whether or not the test succeeded.  'n' is the test's number.
Anything after this on the line (up to the first '#' if present) is 
considered to be the name of the test.  Naming tests is optional, but 
encouraged.

A test may be written which is conditional, and may need to be skipped.
For example, the netinet tests require 'options INET' in the kernel.
A test may be skipped by printing '# skip Reason for skipping' after the
test name.  For example,

    ok 1 - netinet # skip 'options INET' not compiled in

A test may be flagged as 'todo'.  This indicates that you expect the test
to fail (perhaps because the necessary functionality hasn't been written
yet).  'todo' tests are expected to fail, so when they start working the
test framework can alert you to this happy occurrence.  Flag these tests 
with a '# TODO' comment after the test name

    not ok 1 - infiniteloop # TODO write test for an infinite loop

This is modelled on the protocol followed by the Test::Harness Perl
module (and therefore much of the automated testing carried out by the 
Perl community).  More documentation can be found at:

    http://search.cpan.org/~petdance/Test-Harness-2.42/lib/Test/Harness.pm

To run the tests and parse their output install the devel/p5-Test-Harness
port.  This includes the prove(1) command which is used to run the tests
and collate the output.

    prove geom_concat		# run all the tests in geom_concat
    prove -r lib		# run all tests in lib/, and subdirectories
    prove -r -v lib		# as above, with verbose output
    prove -r			# run *all* the tests

Tests that are for parts of the base system should go into a directory here
which is the same as their path relative to src/, for example the uuencode(1)
utility resides in src/usr.bin/uuencode so its regression test resides in
src/tools/regression/usr.bin/uuencode.

To avoid the pre-commit check program complaining about the lack of
CVS keywords in test data files, use a .in suffix for input files and
a .out suffix for output files.

To execute individual regression tests for binaries that you are
developing, add their directory in the path before running the tests.
Example:
cd /usr/src/tools/regression/usr.bin
(PATH=/home/user/src/experimental/jot:$PATH ; make SUBDIR=jot)

Please make a subdir per other regression test, and add a brief description to
this file.
