-Subject: [PATCH] Fix race conditions running external commands with job
- control on
-
-When ksh is compiled with SHOPT_SPAWN (the default), which uses
-posix_spawn(3) or vfork(2) (via sh_ntfork()) to launch external
-commands, at least two race conditions occur when launching
-external commands while job control is active. See:
-https://bugs.launchpad.net/ubuntu/+source/ksh/+bug/1887863/comments/3
-https://www.mail-archive.com/ast-developers@research.att.com/msg00717.html
-
-The basic issue is that this performance optimisation is
-incompatible with job control, because it uses a spawning mechanism
-that doesn't copy the parent process' memory pages into the child
-process, therefore no state that involves memory can be set before
-exec-ing the external program. This makes it impossible to
-correctly set the terminal's process group ID in the child process,
-something that is essential for job control to work.
-
-src/cmd/ksh93/sh/xec.c:
- Use sh_fork() instead of sh_ntfork() if job control is active.
-  This uses fork(2), which is 30%-ish slower on most sytems, but
-  allows for correctly setting the terminal process group.
-
-Fixes: https://github.com/ksh93/ksh/issues/79

-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.
-
-(cherry picked from commit bef4fee404d8e24b38fce66420c14a39ac4a123e)

-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.

-From f9d28935bb93fe7336ba8c5eab4231050de2e11e Mon Sep 17 00:00:00 2001
-From: Martijn Dekker <martijn@inlv.org>
-Date: Fri, 10 Jul 2020 01:38:13 +0100
-Subject: [PATCH] Fix UTF-8 shellquoting for xtrace, printf %q, etc.
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-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; : 'aeu aéu')
-+ : $'aeu a\u[e9]u'
-$ (set -x; : 'aéu aeu')
-+ : 'aéu aeu'
-$ (set -x; : '正常終了 aeu')
-+ : '正常終了 aeu'
-$ (set -x; : 'aeu 正常終了')
-+ : $'aeu \u[6b63]\u[5e38]\u[7d42]\u[4e86]'
-
-This issue was originally reported by lijo george in May 2017:
-https://www.mail-archive.com/ast-developers@lists.research.att.com/msg01958.html
-
-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.

+Subject: [PATCH] vi: Fix recalling lines starting with whitespace (re:
+ 5eeeed06)
+
+@jghub reports:
+> if for some reason a command is entered with leading whitespace,
+> the leading whitespace is preserved in the history file (in
+> ksh93u+, too). such commands can be recalled from history in 93u+
+> without problem, both, in vi and emacs mode.
+>
+> but in 93u+m such entries are simply ignored when using vi-mode
+> (set -o vi), i.e. the k and j commands skip over such entries.
+> emacs mode still works just fine.
+
+Analysis: the blankline() function in vi.c and emacs.c is used to
+check for whitespace up to the cursor position. This is used for
+tab completion and fullscreen editor invocation, where that is
+okay, and for history recall, where that should be checking the
+entire line instead.
+
+In emacs.c this was not really a problem because arrowing up (or
+^P) positions the cursor to the end of the line anyway. But in vi,
+arrowing up (or 'k') positions the cursor at the beginning.
+
+src/cmd/ksh93/edit/vi.c:
+- Amend blankline() with an 'uptocursor' argument. If nonzero, it
+  checks the current line for whitespace up to the cursor position,
+  otherwise it checks the entire line.
+- Pass uptocursor==0 to blankline() for history recall and 1 for
+  tab completion.
+
+src/cmd/ksh93/edit/emacs.c:
+- Apply the same change here for consistency, even though it's
+  perhaps not really necessary. If ever a form of recall is added
+  that doesn't position the cursor at the end, then that won't
+  introduce this bug there.
+
+Thanks to @pghvlaans for input into the fix.
+Resolves: https://github.com/ksh93/ksh/issues/799

+
+src/cmd/ksh93/sh/init.c,
+src/cmd/ksh93/include/shell.h:
+- Move the static 'shlvl' in init.c to the sh state struct, so that
+  'sh.shlvl' can be accessed from the entire ksh93 code base.
+- Change its type from int to int32_t -- this is more correct as
+  nv_getval() uses this type to retrieve the value. In practice,
+  this makes no difference because sizeof(int) == sizeof(int32_t),
+  but this is not guaranteed by the standards.
+
+src/cmd/ksh93/bltins/misc.c:
+- Access sh.shlvl directly instead of dereferencing the SHLVL value
+  pointer, as this pointer is invalidated upon 'unset SHLVL'. This
+  fixes the bug.

+Subject: [PATCH] Add forking workaround for block stdout redir (re: e373e8c1)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Reproducer:
+
+    ok=$({ true >&2; } >&2; echo OK); echo $ok
+
+This should output "OK" but currently outputs nothing.
+
+Looks like the sh_subfork() workaround must also be implemented for
+the TSETIO case in sh_exec(), as that is where redirections for
+blocks and compound commands are handled. This avoids inconsistent
+behaviour that happens if sh_subfork() is called later for the
+inside redirection.
+
+src/cmd/ksh93/sh/xec.c: sh_exec(): case TSETIO:
+- Also fork if standard output redirections attached to blocks are
+  executed within a non-subshare command substitution.
+
+Thanks to Vincent Mihalkovič (@vmihalko) for the report.

+Subject: [PATCH] Fix segfault upon SIGWINCH after 'stty -echo' (re: 83630f9d)
+
+After disabling terminal echo (stty -echo), ksh either crashes or
+writes garbage to the terminal upon resizing the terminal window.
+This also affects the use of ksh for 'M-x shell' in emacs.
+
+Analysis: The ed_viread and ed_emacsread functions declare buffers
+as local (automatic) variables that are destroyed when the function
+exits, but other functions then access then using globally declared
+pointers in structs of type Edit_t, Emacs_t and Vi_t.
+
+However, upon 'stty -echo', the terminal cannot be set to raw mode,
+so the tty_raw call fails in these two functions. At this point,
+they fall back to ed_read and return, never initialising those
+pointers. But the SIGWINCH handling routine in edit.c calls redraw
+routines that depend on those pointers being valid -- and crash.
+
+src/cmd/ksh93/edit/emacs.c: ed_emacsread():
+- Attempt to set raw mode before doing or initialising anything
+  else: move the tty_raw call and ed_read fallback to the start.
+  This avoids superfluous init and makes more sense.
+- Before returning, reset all global pointers that point to this
+  function call's local variables to NULL. (To aid with this, use a
+  'done' goto label and an 'r' variable for the return code.) This
+  ensures these pointers will be either valid or NULL, making
+  debugging easier, as well as allowing the code to check for this.
+
+src/cmd/ksh93/edit/vi.c: ed_viread():
+- Same changes as for emacs.
+
+src/cmd/ksh93/edit/edit.c: ed_read():
+- If e_prompt is NULL, that is now an indication that ed_emacsread
+  or ed_viread are not being used because the tty_raw call failed;
+  therefore, skip SIGWINCH handling, except for flushing the notify
+  buffer (see 667034ff). This fixes the crash.
+
+Thanks to @nickpapadonis for the report.

+Subject: [PATCH] Fix long multibyte characters paste issue via ssh (#840)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When I paste long multibyte characters(over 80 byte) to ksh via
+SSH, the characters are not displayed correctly. For example, the
+following input demonstrates the issue. ja_JP.UTF-8 encoding is
+used.
+
+Expected command line display:
+$ echo "長い文字列を入れるとkshで文字列が乱れる場合があるようです"
+
+Actual command line display:
+$ です"echo "長い文字列を入れるとkshで文字列が乱れる場合がある
+...with the cursor over the 'e' in 'echo'.
+
+This issue appears to be caused by the ed_read() function splitting
+a multibyte character sequence when reading into an 80-byte buffer.
+This leads to incorrect character interpretation and display.
+
+Therefore, we edited the code to handle the case where the buffer
+size is full in the middle of a multi-byte character.
+
+src/cmd/ksh93/sh/edit.c:
+- putstack():
+  - Before retrying to interpret a multibyte character in case of a
+    split due to end of buffer, restore the start position 'p'.
+  - Fix zeroing out errno = EILSEQ.
+- ed_getchar(): Avoid a potential buffer overflow in 'readin';
+  allow for an extra multibyte character, not merely an extra byte.

+Subject: [PATCH] Fix 'stty -echo' in scripts (re: 41ebb55a)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Vincent Mihalkovič (@vmihalko) reports:
+> In ksh versions later than v1.0.0-beta.1, setting stty -echo in a
+> script no longer works as expected. This issue did not occur in
+> earlier versions.
+>
+> I performed a git bisect between the last known good tag (reboot)
+> and the first known bad tag (v1.0.0-beta.1). The regression was
+> introduced in commit 41ebb55a.
+>
+> Reproducer:
+>   read a
+>   stty -echo
+>   read b
+>
+> Expected Behavior:
+>   • Input for a should be visible.
+>   • Input for b should not be echoed to the terminal.
+>
+> Actual Behavior:
+>   • Input for a is visible as expected.
+>   • Input for b is also visible, despite stty -echo being set.
+
+Analysis:
+
+The problem was that the tty_set(-1, 0, NULL) call below, which
+invalidates saved terminal attributes, was no longer being executed
+when running a script (note that job.jobcontrol is 0/false for
+scripts). See edit.c for the tty_set function and what it does.
+
+src/cmd/ksh93/sh/jobs.c
+1423:	else if(job.jobcontrol)
+1424:	{
+1425:		if(pw->p_pid == tcgetpgrp(JOBTTY))
+1426:		{
+...skipped for brevity...
+1430:		}
+1431:		tty_set(-1, 0, NULL);
+1432:	}
+
+So, after running an external command such as stty, terminal
+attributes that should have been invalidated were restored upon the
+next 'read'. This was undoing the effect of the stty command.
+
+src/cmd/ksh93/sh/jobs.c: job_wait():
+- Move the test for job.jobcontrol so that saved terminal
+  attributes are again invalidated after running an external
+  command when job control for interactive shells is not active.
+
