188e46ab03 Add supporting changes for Add limited sandbox capability to "make check"
Non-tests/... changes:
- Add HAS_TESTS= to Makefiles with libraries and programs to enable iteration
  and propagate the appropriate environment down to *.test.mk.

tests/... changes:
- Add appropriate support Makefile.inc's to set HAS_TESTS in a minimal manner,
  since tests/... is a special subdirectory tree compared to the others.

27181846bb pgrep naively appends the delimiter to all PIDs including the last
e.g. "pgrep -d, getty" outputs "1399,1386,1309,1308,1307,1306,1305,1302,"
Ensure the list is correctly delimited by suppressing the emission of the
delimiter after the final PID.

01df7d10a5 Remove SUBDIR ordering/uniquifying in *bin/Makefile
After the addition of SUBDIR.yes, uniquifying/ordering the SUBDIRs doesn't
make a whole lot of sense, and it's in effect a half measure.

Ordering SUBDIR (after adding SUBDIR.yes to it) in bsd.subdir.mk is a
separate change that warrants more discussion/testing, because while
the SUBDIR_PARALLEL work largely fixed dependency ordering for SUBDIRs,
there might be downstream FreeBSD consumers that rely on the SUBDIR
ordering.

With this patch, ",n" is an abbreviation for "1,n", ";n" abbreviates
".;n". The "n," and "n;" variants mean "n,n" and "n;n", respectively.
Also, piping to a shell command does not count as a save, so don't reset
the modified flag.

If CDPATH is used non-trivially or the operand is "-", cd writes the
directory actually switched to. (We currently do this only in interactive
shells, but POSIX requires this in non-interactive shells as well.)

As mentioned in Austin group bug #1045, cd shall not return an error while
leaving the current directory changed. Therefore, ignore any write error.

63bd650f4b ln(1): fix -F behavior
When '-F' option is used, the target directory needs to be unlinked.
Currently, the modified target ("target/source") is being unlinked, and
since it doesn't yet exist, the original target isn't removed.
This is fixed by skipping the block where target is modified to
"target/source" when '-F' option is set.
Hence, a symbolic link (with the same name as of the original target) to
the source_file is produced.

Update the test for ln(1) to reflect fix for option '-F'

If param in ${param#%##%%word} is not set, the word is not expanded (in a
deviation of POSIX shared with other ash variants and ksh93). Erroneously,
the pointer in the list of commands (argbackq) was not advanced. This caused
the wrong command to be executed later if the outer word contained another
command substitution.

Example:
  echo "${unsetvar#$(echo a)}$(echo b)"
wrote "a" but should write "b".

ef1d40da16 ps(1): Fix -w + UNLIMITED handling
A follow-up fix for r314685.

Because the -w flag is parsed after ps(1) infers termwidth from COLUMNS and
stdout, and UNLIMITED happens to be the zero value, the single -w flag in
combination with a non-terminal stdout or COLUMNS=0 could result in output
truncated at 131 characters.  (Despite the output being unlimited without
-w.)

Obviously, adding more -w shouldn't truncate output lines.

The committed patch is from bdrewery@, and I've reviewed and tested it.

586fd24857 sh: Fix crash if a -T trap is taken during command substitution.
Code like  t=$(stat -f %m "$file")  segfaulted if -T was active and a trap
was taken while the shell was waiting for the child process to finish.

What happened was that the dotrap() call in waitforjob() was hit. This
re-entered command execution (including expand.c) at a point not expected by
expbackq(), and global state (unallocated stack string and argbackq) was
corrupted.

To fix this, change expbackq() to prepare for command execution to be
re-entered.

9c4241c3d7 ps(1): Only detect terminal width if stdout is a tty
If stdout isn't a tty, use unlimited width output rather than truncating to
79 characters.  This is helpful for shell scripts or e.g., 'ps | grep foo'.

This hardcoded width has some history: In The Beginning of History[0], the
width of ps was hardcoded as 80 bytes.  In 1985, Bloom@ added detection
using TIOCGWINSZ on stdin.[1]  In 1986, Kirk merged a change to check
stdout's window size instead.  In 1990, the fallback checks to stderr and
stdin's TIOCGWINSZ were added by Marc@, with the commit message "new
version."[2]

OS X Darwin has a very similar modification to ps(1), which simply sets
UNLIMITED for all non-tty outputs.[3]  I've chosen to respect COLUMNS
instead of behaving identically to Darwin here, but I don't feel strongly
about that.  We could match OS X for parity if that is desired.

7cca93e61a sh: Do not import IFS's value from the environment.
Per Austin group issue #884, always set IFS to $' \t\n'. As before, IFS will
be exported iff it was in the environment.

Most shells (e.g. bash, ksh93 and mksh) already did this. This change
improves predictability, in that scripts can simply rely on the default
value.

However, the effect on security is little, since applications should not be
calling the shell with attacker-controlled environment variable names in the
first place and other security-sensitive variables such as PATH should be
and are imported by the shell.

When using a new sh with an old (before 10.2) libc wordexp(), IFS is no
longer passed on. Otherwise, wordexp() continues to pass along IFS from the
environment per its documentation.

files by using getconf(1) and skip them if not.  Note that the support for
this query was just added to getconf(1) in r304694.

- lib/msun/exp_test:exp2_values now passes with clang 3.8.0

The Makefiles in contrib/netbsd-tests were pruned as they have no value

b7a25e63b6 When a debugger attaches to the process, SIGSTOP is sent to the
target.  Due to a way issignal() selects the next signal to deliver
and report, if the simultaneous or already pending another signal
exists, that signal might be reported by the next waitpid(2) call.
This causes minor annoyance for debuggers, which must be prepared to
take any signal as the first event, then filter SIGSTOP later.

More importantly, for tools like gcore(1), which attach and then
detach without processing events, SIGSTOP might leak to be delivered
after PT_DETACH.  This results in the process being unintentionally
stopped after detach, which is fatal for automatic tools.

The solution is to force SIGSTOP to be the first signal reported after
the attach.  Attach code is modified to set P2_PTRACE_FSTP to indicate
that the attaching ritual was not yet finished, and issignal() prefers
SIGSTOP in that condition.  Also, the thread which handles
P2_PTRACE_FSTP is made to guarantee to own p_xthread during the first
waitpid(2).  All that ensures that SIGSTOP is consumed first.

Additionally, if P2_PTRACE_FSTP is still set on detach, which means
that waitpid(2) was not called at all, SIGSTOP is removed from the
queue, ensuring that the process is resumed on detach.

In issignal(), when acting on STOPing signals, remove the signal from
queue before suspending.  Otherwise parallel attach could result in
ptracestop() acting on that STOP as if it was the STOP signal from the
attach.  Then SIGSTOP from attach leaks again.

As a minor refactoring, some bits of the common attach code is moved
to new helper proc_set_traced().
