Here is the ninth ksh 93u+m/1.0 bugfix release. This release contains many fixes of old and not-so-old bugs (including a couple of regressions in the printf built-in introduced in 93u+m/1.0.5), adds Android/Termux as a supported platform, and reintroduces the ability to build a dynamically linked ksh (with libast, libdll, libcmd, and libshell available for other applications to use) on most supported platforms.

Main changes between ksh 93u+m/1.0.8 and 93u+m/1.0.9:

  • Android/Termux is now a supported platform. Build dependencies: binutils, clang, getconf. Runtime dependencies (optional): ncurses-utils, getconf.
  • Reintroduced support for building a dynamically linked ksh(1)/shcomp(1), with libast, libdll, libcmd, and libshell available to other programs as dynamic libraries. bin/package install /your/basepath will install development headers. The dynamically linked version is built in a dyn subdirectory; there are no changes to the statically linked version. Dynamic linking is currently tested and supported on Linux, Android, macOS, all the BSDs, illumos, Solaris, QNX, and Haiku.
  • On systems where the external printf(1) utility supports deprecated pre-POSIX syntax for formatters starting with -, ksh now adapts its built-in printf to match, for compatibility with system scripts. However, ksh's built-in printf options such as -v or --man are not affected.
  • Fixed a regression in the printf built-in, introduced in 93u+m/1.0.5, where each instance of \0 or %Z in the format operand caused a string argument to be incorrectly skipped.
  • Fixed a regression, introduced in 93u+m/1.0.5, in ordinal specifiers in printf %T date specifications. For example, printf '%(%F)T\n' '4th tuesday in march 2016' wrongly printed '2016-04-09' and now again correctly prints '2016-03-22'.
  • Fixed a regression of return within traps, reintroduced in 93u+m/1.0.8 after being fixed in 93u+m/1.0.0. The regression caused a return or exit with no arguments to assume the before-trap exit status instead of that of the last-run command. This broke the shipped autocd function.
  • Fixed a longstanding bug in shell arithmetic: the representation of negative integers with a base other than 10 was incorrectly treated as unsigned long. For example, typeset -i16 n=-12; echo $n now correctly outputs -16#c and no longer ouputs 16#fffffffffffffff4.
  • Fixed a bug, introduced in ksh93q+ 2005-05-22, that stopped an append assignment from working together with a declaration command. For example,typeset var+=value or export var+=value now again work as expected.
  • Fixed a longstanding bug where the default terminal width for typeset -L, -R, or -Z, if not given, was miscalculated for multibyte or control characters.
  • Fixed: expansions of name references in loops were incorrectly treated as invariant so they yielded the wrong values.
  • If a .get or .getn discipline function is set for a variable, it is no longer incorrectly triggered when performing an arithmetic assignment on that variable; only the .set discipline is now triggered (as documented).
  • Many other bug fixes (see the NEWS file).
