+src/cmd/ksh93/edit/history.c: hist_trim():
+- Print a warning and return if unlink(2) fails. The warning tells
+  the user to check the history file's parent directory is
+  writable. This is the best I realistically do for now, because
+  this function's basic method assumes a writable parent directory.
+- The temp file fallback is deleted because it's fundamentally
+  flawed: it assumes the temp file is made on the same volume as
+  the history file and can simply be rename(2)'d in place. Even
+  on systems where this is the case, it doesn't appear to be
+  working correctly, but this is not worth looking into.

+Subject: [PATCH] Re-fix use of strdup on a NULL pointer (re: 9a9da2c2) (#718)
+
+Thank you @lzaoral for debugging this issue and creating this
+reproducer:
+
+$ tty   # check that the shell is connected to a pseudoterminal
+/dev/pts/4
+$ mkdir /var/tmp/chroottest
+$ dnf --releasever=39 --installroot=/var/tmp/chroottest install ksh

+        sudo tee /var/tmp/chroottest/etc/ksh_audit
+$ sudo chroot /var/tmp/chroottest /bin/ksh -lic 'exit 0'
+(ksh segfaults)
+
+Analysis: On Linux, ttyname(3)[*] may fail if:
+
+* EBADF  Bad file descriptor.
+* ENODEV fd refers to a slave pseudoterminal device but the
+         corresponding pathname could not be found [...].
+* ENOTTY fd does not refer to a terminal device.
+
+Calling isatty(3) before ttyname(3) only prevents the first and
+third cases.

+Subject: [PATCH] Fix `set +r` so that it cannot unset the restricted option
+
+The ksh man page documents that the restricted option cannot be
+unset once it is set, which means `set +r` should be invalid.
+While this was true for `set +o restricted`, `set +r` was causing
+the restricted option to be unset. The fix for this problem comes
+from one of Solaris' patches, which adds an error check to prevent
+this behavior.
+
+Solaris' patch:
+https://github.com/oracle/solaris-userland/blob/master/components/ksh93/patches/020-CR6919590.patch
+
+src/cmd/ksh93/sh/args.c:
+ - Add an error check to stop `set +r` from unsetting the
+   restricted option.
+
+src/cmd/ksh93/tests/restricted.sh:
+ - Add two regression tests to make sure the restricted option
+   cannot be unset.

+Subject: [PATCH] Fix blocked signals after fork(2)ing external command in
+ subshell
+
+When the classic fork/exec mechanism was used (via sh_fork()) to
+run an external command from within a non-forking subshell, SIGINT
+was blocked until that subshell was exited. If a subsequent loop
+was run in the subshell, it became uninterruptible, e.g.:
+
+   $ arch/*/bin/ksh -c '(/usr/bin/true; while :; do :; done); exit'
+   ^C^C^C^C^C
+
+src/cmd/ksh93/sh/xec.c:
+- sh_fork() did not reset the savesig variable in the parent part
+  of the fork when running in a virtual subshell. This had the
+  effect of delaying signal handling until exiting the subshell.
+  There is no reason for that subshell check that I can discern, so
+  this removes it.
+      I've verified that this causes no regression test failures
+  even when ksh is compiled with -DSHOPT_SPAWN=0 which means the
+  classic fork/exec mechanism is always used.

+Subject: [PATCH] Fix crash/freeze upon interrupting command substitution with
+ pipe
+
+On some systems (at least Linux and macOS):
+
+1. Run on a command line: t=$(sleep 10|while :; do :; done)
+2. Press Ctrl+C in the first 10 seconds.
+3. Execute any other command substitution. The shell crashes.
+
+Analysis: Something in the job_wait() call in the sh_subshell()
+restore routine may be interrupted by a signal such as SIGINT on
+Linux and macOS. Exactly what that interruptible thing is remains
+to be determined. In any case, since job_wait() was invoked after
+sh_popcontext(), interrupting it caused the sh_subshell() restore
+routine to be aborted, resulting in an inconsistent state of the
+shell. The fix is to sh_popcontext() at a later stage instead.
+
+src/cmd/ksh93/sh/subshell.c: sh_subshell():
+- Move the sh_popcontext() call to near the end, just after
+  decreasing the subshell level counters and restoring the global
+  subshell data struct to its parent. This seems like a logical
+  place for it and could allow other things to be interrupted, too.
+- Get rid of the if(shp->subshell) because it is known that the
+  value is > 0 at this point.
+- The short exit routine run if the subshell forked now needs a new
+  sh_popcontext() call, because this is handled before restoring
+  the virtual subshell state.

+MIME-Version: 1.0

+Content-Transfer-Encoding: 8bit
+
+This fixes an annoying issue in the shell's quoting algorithm
+(used for xtrace (set -x), printf %q, and other things) for UTF-8
+locales, that caused it to encode perfectly printable UTF-8
+characters unnecessarily and inconsistently. For example:
+

+$ (set -x; : 'aéu aeu')
+ : 'aéu aeu'

+$ (set -x; : 'aeu 正常終了')

+
+src/cmd/ksh93/sh/string.c:
+- Add is_invisible() function that returns true if a character is a
+  Unicode invisible (non-graph) character, excluding ASCII space.
+  Ref.: https://unicode.org/charts/PDF/U2000.pdf
+- Use a fallback in is_invisible() if we cannot use the system's
+  iswprint(3); this is the case for the ksh C.UTF-8 locale if the
+  OS doesn't support that. Fall back to a hardcoded blacklist of
+  invisible and control characters and put up with not encoding
+  nonexistent characters into \u[xxxx] escapes.
+  Ref.: https://unicode.org/charts/PDF/U2000.pdf
+- When deciding whether to switch to $'...' quoting mode (state=2),
+  use is_invisible() instead of testing for ASCII 0-127 range.
+- In $'...' quoting mode, use is_invisible() to decide whether to
+  encode wide characters into \u[xxxx] escapes.
+
+src/cmd/ksh93/tests/builtins.sh:
+- Add regression tests for shellquoting Arabic, Japanese and Latin
+  UTF-8 characters, to be run only in a UTF-8 locale. The Arabic
+  sample text[*] contains a couple of direction markers that are
+  expected to be encoded into \u[xxxx] escapes.
