Name        : mksh
Product     : Fedora 17
Version     : 44
Release     : 1.fc17
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; speed up hash tables at size cost
 - [tg] MKSH_SMALL no longer implies -fno-inline
 - [tg] Support optional seed in ${parameter@#seed} for security
 - [tg] New Build.sh environment configurable: LDSTATIC (empty)
 - [tg] Improve LTO effect by always adding our copies of distributed utility function sources when linking statically (i.e. LDSTATIC is not empty)
 - [tg] Drop deprecated hack for lines beginning with an exclamation mark
 - [tg] No longer interpret numbers beginning with a 0 digit as octal
 - [tg] Attempt to use -fwrapv on more compilers

 - [tg] Add MKSH_NO_CMDLINE_EDITING, MKSH_DISABLE_TTY_WARNING
 - [RT] Port to Coherent UNIX
 - [tg] Enable some options by default for some ports, for instance, since BeOS can never have a controlling tty, the option disabling that warning
 - [tg] Some bugfixes, prompted by RT and Valgrind
 - [RT] Disable sigsuspend(2) on Syllable Desktop
 - [tg] Fix several issues with typeset -p (LP: #993847)
 - [RT] Detect lcc and apply inline fix, e.g. for use with libc5
 - [tg] If klibc, set -DMKSH_NO_LIMITS and check for sigsuspend fix
 - [tg] Fix some issues found by Coverity and some found while fixing
 - [tg] Build.sh options: -t target-filename (instead of mksh); -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] Fix ulimit builtin usage to match what limits we actually know
 - [tg] Allow overriding /etc location, experts only (LP: #1039713)
 - [tg] Update to Unicode 6.1.0
 - [tg, Todd Miller] Avoid changing ps(1) output by accident
 - [tg, ft, Christian Neukirchen] Detect zsh 2.5.02/NeXTstep for Build.sh
 - [tg] Detect musl-gcc wrapper, define _BSD_SOURCE there, which is totally bogus, but musl, just like dietlibc, gets it wrong
 - [tg] Improve compile-time assertions
 - [tg] Repair select builtin without any choices given
 - [tg] Add -DMKSH_GCC55009 hack to avoid some compile-time assertions and introduce arith-mandatory in check.t to substitute for missing that compile-time check; will change
