773e27aeee sh: Fix unalias -a while an alias is currently in use.
It is a rare situation to modify aliases while an alias is currently in use,
but this is handled for plain unalias. Handle it for unalias -a as well.

Do not use macros in the argument specifying the width,
since that's not portable.  While GNU troff can handle it,
mandoc cannot.

8999a290ab sh: Fix executing wrong command with ${unsetvar#$(cmdsubst)}$(cmdsubst).
The parsed internal representation of words consists of a byte string with a
list of nodes (commands in command substitution). Each unescaped CTLBACKQ or
CTLBACKQ | CTLQUOTE byte corresponds to an entry in the list.

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.

246ef54f15 df(1): Allow duplicate -l flags gracefully
Rather than producing a misleading error message when duplicate -l flags are
provided to df(1), simply ignore extra flags and proceed as if only one was
specified.  This seems most reasonable given the usage for -l:

     -l      Only display information about locally-mounted file systems.

l and t flags still conflict, as before.

647672e21f Skip ls tests that use sparse files if these are not supported.
Some of the ls(1) tests create really large sparse files to validate
the number formatting features of ls(1).  Unfortunately, those tests fail
if the underlying test file system does not support sparse files, as is the
case when /tmp is mounted on tmpfs.

Before running these tests, check if the test file system supports sparse
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.

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().

4af86fb4f9 Explicitly NUL terminate the buffer filled by fread().
The fix in r300649 was not sufficient to convince Coverity that the
buffer was NUL terminated, even with the buffer pre-zeroed.  Swap
the size and nmemb arguments to fread() so that a valid lenght is
returned, which we can use to terminate the string in the buffer
at the correct location.  This should also quiet the complaint about
the return value of fread() not being checked.

There is no need to to call strdup() on the value returned by fmt().
The latter calls fmt_argv() which always returns a dynamically
allocated string, and calling strdup() on that leaks the memory
allocated by fmt_argv().  Wave some const magic on ki_args and
ki_env to make the direct assignment happy.  This requires a tweak
to the asprintf() case to avoid a const vs. non-const mismatch.

63a4675d89 Hopefully fix Coverity CID 1008328 (Out-of-bounds write) in /bin/sh.
Replace the magic constant 127 in the loop interation count with
"PROMPTLEN - 1".

gethostname() is not guaranteed to NUL terminate the destination
string if it is too short. Decrease the length passed to gethostname()
by one, and add a NUL at the end of the buffer to make sure the
following loop to find the end of the name properly terminates.

The default: case is the likely cause of Coverity CID 1008328.  If
i is 126 at the top of the loop interation where the default case
is triggered, i will be incremented to 127 by the default case,
then incremented to 128 at the top of the loop before being compared
to 127 (PROMPTLENT - 1) and terminating the loop. Then the NUL
termination code after the loop will write to ps[128].  Fix by
checking for overflow before incrementing the index and storing the
second character in the buffer.

These fixes are not guaranteed to satisfy Coverity. The code that
increments i in the 'h'/'H' and 'w'/'W' cases may be beyond its
capability to analyze, but the code appears to be safe.

430f7286a5 Merge ^/user/ngie/release-pkg-fix-tests to unbreak how test files are installed
after r298107

Summary of changes:

- Replace all instances of FILES/TESTS with ${PACKAGE}FILES. This ensures that
  namespacing is kept with FILES appropriately, and that this shouldn't need
  to be repeated if the namespace changes -- only the definition of PACKAGE
  needs to be changed
- Allow PACKAGE to be overridden by callers instead of forcing it to always be
  `tests`. In the event we get to the point where things can be split up
  enough in the base system, it would make more sense to group the tests
  with the blocks they're a part of, e.g. byacc with byacc-tests, etc
- Remove PACKAGE definitions where possible, i.e. where FILES wasn't used
  previously.
- Remove unnecessary TESTSPACKAGE definitions; this has been elided into
  bsd.tests.mk
- Remove unnecessary BINDIRs used previously with ${PACKAGE}FILES;
  ${PACKAGE}FILESDIR is now automatically defined in bsd.test.mk.
- Fix installation of files under data/ subdirectories in lib/libc/tests/hash
  and lib/libc/tests/net/getaddrinfo
- Remove unnecessary .include <bsd.own.mk>s (some opportunistic cleanup)

Document the proposed changes in share/examples/tests/tests/... via examples
so it's clear that ${PACKAGES}FILES is the suggested way forward in terms of
replacing FILES. share/mk/bsd.README didn't seem like the appropriate method
of communicating that info.
