The test locale1.0 depends on locale support; it is meaningless without a
working LC_MESSAGES.
I added an OptionalObsoleteFiles.inc entry.

When getopts finds an invalid option or a missing option-argument, it should
not reset its state and should set OPTIND as normal. This is an old ash bug
that was fixed long ago in dash. Our behaviour now matches most other
shells.
Only store exit status for a process if that process has not terminated yet.
Test (slow):
exit 7 & p1=$!; until exit 8 & p2=$!; [ "$p1" = "$p2" ]; do wait "$p2";
done; sleep 0.1; wait %1; echo $?
should write "7".
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.
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.
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.
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.
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).
Add the space to avoid alias recursion when the alias is expanded, not when
it is added.
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.
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.

Redo r260506 by using the new TEST_METADATA functionality of bsd.test.mk
to mark the sh(1) and test(1) tests as not supporting root. This is to
get rid of hand-crafted Kyuafiles for these very simple cases.

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
will be the default in Kyua but isn't yet.)

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'
with hot cache.
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.

Although <&0 does nothing, it is a redirection affecting standard input and
should therefore disable the </dev/null redirection implicit in a background
command.
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).

A Ctrl+C should terminate the sleep command.
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

The getpgrp() call is unnecessary: if there is no job control then the
result was not used at all and if there is job control then we are not a
subshell and our process group ID is equal to our process ID (rootpid).
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.

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.
The erflag argument was only used by old-style (``) command substitutions.
We can remove it and handle the special case in the command substitution
code.
