Name : mksh Product : Fedora 18 Version : 44 Release : 1.fc18 URL : http://www.mirbsd.de/mksh.htm Summary : MirBSD enhanced version of the Korn Shell Description : mksh is the MirBSD enhanced version of the Public Domain Korn shell (pdksh), a bourne-compatible shell which is largely similar to the original AT&T Korn shell. It includes bug fixes and feature improvements in order to produce a modern, robust shell good for interactive and especially script use, being a bourne shell replacement, pdksh successor and an alternative to the C shell. -------------------------------------------------------------------------------- Update Information: R44 contains these bugfixes: - [tg] "$@" always generates words; bug spotted by engla in IRC - [tg] Optimise print_columns display to use the screen space better Please upgrade to mksh R43 (or stick on R41c) because of… - [tg] Do not permit $'…' and $"…" in anything that looks like a string, as old scripts, like ncurses’, depend on behaviour not guaranteed by POSIX regarding unescaped dollar signs there - [dalias] Make detection of function prototypes more reliable - [tg] Quote setenv arguments for eval properly in dot.mkshrc - [tg] Validate parameter names for typeset, export, etc. - [tg] Provide a classic BSD echo builtin for /bin/sh on MidnightBSD - [tg] When generating Makefrag.inc put list of check_categories inside - [tg] Actually test all echo(1) flavours and MidnightBSD /bin/sh hacks mksh R42b and R41c fix regressions: - [tg] Correctly initialise memory (Debian #700604) - [tg] LP#1104543 fix was too strict (Debian #700526) mksh R42 brings back the release\ {early,often} scheme: - [tg] Make -DMKSH_DISABLE_EXPERIMENTAL a nop again - [tg] Quell some LLVM+Clang warnings; overhaul scan-build assert(3)s - [tg, RT] Bunch of portability and build system fixes - [tg] Re-enable ${ precmd;} in dot.mkshrc and fix it to retain the errorlevel - [RT] Port to Minix-vmd, QNX 4, Watcom C; begin porting to SunOS 4.1.1, Xenix, ISC (Interactive) Unix - [tg] Prefer const-clean sys_errlist[] to strerror(3) - [tg] Permit $"…" and $'…' everywhere except in the body of here documents that are not here strings - [tg] Use full recursive parser for double-quoted here strings, and reuse code between here strings and here documents - [tg] #ifdef DEBUG_LEAKS free all fds and memory on exit (LP#1106116) - [tg] Don’t close stdout/stderr with redirections, dup /dev/null instead, always, both in dot.mkshrc and the testsuite, it does break! - [tg] Handle ${ …;} like functions in that local and return DWIW; use it for the big chunk in $PS1 to avoid fork(2)ing (at cost of tempfiles; dot.mkshrc is a sample, adjust to your needs) - [tg] Document invalid ${a/b/c} patterns in manpage (Debian #698678) mksh R41b is a bugfix-only release off a stable branch: - [tg] Fix gettimeofday(2) detection at build time (warning) - [RT, tg] Build.sh: catch non-working dash printf builtin - [chris2, dalias, tg] Remove musl libc workaround and use _GNU_SOURCE which they kindly aliased to _ALL_SOURCE, which is implemented now - [tg] Fix getn and some cases of possible array bounds trespasses - [chris2, dalias, tg] Use -fno-asynchronous-unwind-tables with GCC - [tg] Fix a few warnings from libFirm/cparser (mostly -Wsign-compare) - [tg] Correct mistake when doing hashtable lookup collision resolution - [tg] Fix running the ERR and EXIT traps in situations with set -e and/or eval (also closes Debian #696823) - [tg] Fix “command shift”, reported by «ormaaj:#!/bin/mksh» - [Torsten Sillke] Unbreak linking on AIX (remove -qextchk) - [tg] Fix regression wrt lists in functions and “set -e” (LP#1104543) mksh R41 brings a number of bugfixes and new features: - [tg] Drop “set ±o arc4random” (deprecated in R40) - [tg] Drop old Build.sh -long-options (deprecated in R40) - [tg] Change the internal hash algorithm from Bob Jenkins’ one-at-a-time to its NUL-counting, always-changing, better-avalanching MirOS variant NZAAT (with feedback from ciruZ; 75% fill level is reasonable; names tbd in Mirkev/MirJSON) - [tg] Use $'…' for non-ASCII parameters for re-entry printing - [tg] Use sane spelling of “read-only” consistently - [tg] Improve tree -DDEBUG functions (internal/developer use) - [tg] Reduce stack usage a bit;

-L to build a legacy mksh, current changes: different $KSH_VERSION “LEGACY KSH” instead of “MIRBSD KSH”; purely for running ksh88 and pdksh scripts; no command line editing; use traditional “set -- $(getopt …); echo $?” mode always; do not keep file descriptors private; parse leading-zero-digit numbers as octal; no mksh extension -T; use “long”, not “int32_t”, for arithmetics - [tg] fix trimming with positional parameters (Debian #48453) - [tg] ensure that case end tokens are not mixed up (Debian #220272) - [tg] make alias definitions in mksh -c work (Debian #517009), hack - [tg] Apply speed improvements and add MKSH_SMALL_BUT_FAST - [tg] Fix CONSERVATIVE_FDS use-before-definition bug - [tg] Correct two regressions when tab-completing (LP: #1025843) and fix bugs in the same code wrt. completion display and other expansions - [tg] Make quoted output of “typeset -p” AT&T ksh93 compatible - [tg] Implement ${foo@Q} like ${foo:Q} in make(1) - [tg] Remove some unused code;

keep trying in the face of EINTR - [tg] Fix severe regression wrt. initialising tty(4) states - [tg] Improve testsuite, build-time checks and debugging output - [tg, RT, winstonw] Improve portability to BeOS (works), Cygwin (good), Dell UNIX (works somewhat, but not with gcc), LynxOS (works somewhat), NeXTstep (works but not OpenStep 4.2), USL C compiler, SCO OpenServer (good), SCO UnixWare (good), Plan 9 (still broken), Syllable Desktop (broken?) - [tg] rlim_t is supposed to be unsigned - [tg] Some code, warning and spelling cleanup - [tg] New Build.sh environment configurable: AWK (= awk) - [tg, DONG-DONG YANG] Add safety net in the Emacs line editing code - [tg] No longer rely on env(1), id(1), printf(1) in the testsuite, and strcasecmp(3), strcasestr(3), strncasecmp(3) in the code - [tg, stsc, RT] Reduce system requirements of check.pl further mksh R40e is another must-have bugfix update: - [tg, Jilles Tjoelker] skip readonly check in unevaluated ternary twig - [tg, anonymous] fix all remaining ifs.sh testcases - [tg] No longer try to build with GCC and C99 extensions - [tg, Jilles Tjoelker] Do not expand aliases in COMSUB twice - [tg] Honour UTF-8 multi-byte character boundaries when doing partial tab-completion insertions (LP: #909025) to fix RedHat BZ#745702 - [tg] Fix R40 (BZ#496791) regression with IOACT in TIF (LP: #907224) - [tg, ft] Darn persistent history code worst offenders (LP: #906914) - [tg] Fix some gc-sections, GCC and Clang/scan-build warnings/issues - [tg, 28C3] dot.mkshrc hash functions: partially address LP: #909818 - [tg] Only compile divmod(0x80000000, -1) code in when not unneeded - [tg, RT] Move mirtoconf checks and INCLUDES_ONLY parts of sh.h around to ensure prerequisites are always available - [tg, RT, ir0nh34d] Pass mksh.exe to testsuite, if such thing is generated, and deal with Cygwin passing just “mksh” in argv[0] in such cases - [tg] Imply -DMKSH_ASSUME_UTF8=0 on MSYS;
