3cbab1b573 Make bsd.test.mk the only public mk fragment for the building of tests.
Change {atf,plain,tap}.test.mk to be internal implementation details of
bsd.test.mk.  Makefiles that build tests should now only include bsd.test.mk
and declaratively specify what they want to build, without worrying about
the internal implementation of the mk files.

The reason for this change is to permit building test programs of different
interfaces from a single directory, which is something I had a need for
while porting tests over from src/tools/regression/.

Additionally, this change makes it possible to perform some other requested
changes to bsd.test.mk in an easier manner.  Coming soon.

6139448a86 sh: Successfully do nothing when killing a terminated job.
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.

d941f4e61c sh: Simplify expari().
Redo expari() like evalvar(). This makes the logic more understandable and
avoids possible problems if arithmetic expansion occurs if CTLESC characters
are not generated (looking backwards for CTLARI is not generally possible in
that case but the old code tried anyway).

This adds an extra argstr() recursion.

9b565c0250 sh: Allow aliases to force alias substitution on the following word.
If an alias's value ends with a space or tab, the next word is also
checked for aliases.

This is a POSIX feature. It is useful with utilities like command and
nohup (alias them to themselves followed by a space).

5b4046f60f sh: Solve the alias recursion problem in a less hackish way.
Add the space to avoid alias recursion when the alias is expanded, not when

As a result, displaying an alias via command -v, command -V or type no
longer erroneously appends a space. Adjust the tests so they now require
this bug to be absent.

296c7c9901 sh: Remove SIGWINCH handler and just check for resize before every read.
The SIGWINCH handler triggers breakage in libedit which is hard to fix; see
PR bin/169773.

Also, window size changes while a program is in foreground (and it rather
than sh will receive SIGWINCH) will now be picked up automatically.

Downside: it is now certain that a resize is only processed after pressing
<Enter>. If libedit is fixed, sh will most likely have to be changed also.

7fc96b0152 Use TAP_TESTS_PERL to register the legacy_test in bin/pax.
Redo r260586 by using the new functionality in tap.test.mk to transparently
support perl-based test programs.

As a side-effect, we get rid of an explicit path to /usr/bin/perl by
replacing it with /usr/local/bin/perl (or as defined in tap.test.mk).

This also fixes the name of the legacy_test source file because this should
have always been legacy_test.pl and not legacy_test.sh.  My mistake when
originally moving the code around without realizing that this was a perl
script.

One of the tests for test(1) fails and some of the tests for sh(1) are
silently bypassed when running as root.

To fix these tests and ensure they all run, mark the test programs for
sh(1) and test(1) as requiring an unprivileged user.  (This should and

ab778292cf sh: Don't check input for non-whitespace if history is disabled.
preadbuffer() maintained a flag whether there was any non-whitespace
character. This flag is only useful when history is enabled (in that case,
lines containing only whitespace are not added to history). Instead, check
using strspn() when history is enabled.

There is an approximate 2% speedup when running
  sh -c '. /etc/rc.subr; . /etc/defaults/rc.conf; source_rc_confs'

cfc6ad9bc6 Migrate tools/regression/bin/ tests to the new layout.
This change is a proof of concept on how to easily integrate existing
tests from the tools/regression/ hierarchy into the /usr/tests/ test
suite and on how to adapt them to the new layout for src.

To achieve these goals, this change:

- Moves tests from tools/regression/bin/<tool>/ to bin/<tool>/tests/.
- Renames the previous regress.sh files to legacy_test.sh.
- Adds Makefiles to build and install the tests and all their supporting
  data files into /usr/tests/bin/.
- Plugs the legacy_test test programs into the test suite using the new
  TAP backend for Kyua (appearing in 0.8) so that the code of the test
  programs does not have to change.
- Registers the new directories in the BSD.test.dist mtree file.

If job control is not enabled, background jobs started with  ... &  ignore
SIGINT and SIGQUIT so that they are not affected by such signals that are
intended for the foreground job. However, this should not prevent
reassigning a different action for these signals (as if the shell invocation
inherited these signal actions from its parent).

  { trap - INT; exec sleep 10; } & wait
A Ctrl+C should terminate the sleep command.

734382a525 Add a resource limit for the total number of kqueues available to the
user.  Kqueue now saves the ucred of the allocating thread, to
correctly decrement the counter on close.

Under some specific and not real-world use scenario for kqueue, it is
possible for the kqueues to consume memory proportional to the square
of the number of the filedescriptors available to the process.  Limit
allows administrator to prevent the abuse.

This is kernel-mode side of the change, with the user-mode enabling

ad7328341a sh: Make return return from the closest function or dot script.
Formerly, return always returned from a function if it was called from a
function, even if there was a closer dot script. This was for compatibility
with the Bourne shell which only allowed returning from functions.

Other modern shells and POSIX return from the function or the dot script,
whichever is closest.

Git 1.8.4's rebase --continue depends on the POSIX behaviour.

ae84eb37bd sh: Fix race condition with signals and wait or set -T.
The change in r238888 was incomplete. It was still possible for a trapped
signal to arrive before the shell went to sleep (sigsuspend()) because a
check was missing or because the signal arrived before in_waitcmd was set.

On SMP, this bug sometimes caused the builtins/wait4.0 test to take 1 second
to execute; it then might or might not fail. On UP, the test almost always
failed.
