mksh R36 released!

The MirBSD Korn Shell R36 has been released yesterday; the Changelog contains more details as usual.

Major changes:

  • Digital UNIX (DEC OSF/1) V2.0 (MIPS) is now supported using the DEC C and ucode toolchain. (We could not run the testsuite, though.)
  • The ‘-Q’ option to Build.sh is gone without replacement.
  • A new option can be enabled by adding -DMKSH_BINSHREDUCED to $CPPFLAGS, intended mostly for Debian. This option adds extra code to determine whether mksh(1) is called as sh or -sh and switch to “set -o posix” mode if so, disabling brace expansion and some security features, because legacy scripts, such as debconf, depend on such reduced functionality /bin/shs.
  • Input lines beginning with an IFS character of IFS white space are no longer pushed into the history. Some other, less surprising, changes were also made to both Emacs and Vi command line editing modes.
  • The arc4random.c contributed file is now stored with the RCS version number appended, and has been updated.

This is a major update with improved stability and compatibility, and as such recommended in general. It has undergone more extensive testing than mksh R35; if there still be bugs, please report to us. Note that some sorts of behaviour are not considered bugs but expected, sometimes due to historical, sometimes compatibility reasons.

Request for Assistance: We are still looking for an OpenBSD committer to import mksh into the ports tree. Furthermore, a Slackware GNU/Linux package is still missing, as well as a PC-BSD PBI, and Macports (former Darwinports) do not carry mksh either. My earlier Minix 3 problem persists, as do the Plan 9 and Syllable Desktop ones.
