In May 2020, when every KornShell (ksh93) development project was abandoned, development was rebooted in a new fork based on the last stable AT&T version: ksh 93u+. Now, one year and hundreds of bug fixes later, the first beta version is ready, and KornShell lives again. This new fork is called ksh 93u+m as a permanent nod to its origin; a standard semantic version number is added starting at 1.0.0-beta.1. Please test the beta and report any bugs you find, or help us fix known bugs.

______
|
|
Fix regression test failures:
|
|
|
|
- There are many regression test failures on NetBSD.
|
|
|
|
- There are some serious regression test failures on OpenBSD when ksh
|
|
is compiled with AST vmalloc disabled, so the system standard malloc(3)
|
|
is used. These probably represent real ksh93 bugs exposed by OpenBSD's
|
|
security hardening mechanisms.
|
|
|
|
- Several known memory leaks have their tests disabled in tests/leaks.sh
|
|
and are marked TODO. These need tracking down and fixing.
|
|
|
|
______
|
|
Fix currently known bugs affecting shell scripting. These are identified by
|
|
their modernish IDs. For exact details, see code/comments in:
|
|
https://github.com/modernish/modernish/tree/0.16/lib/modernish/cap/
|
|
|
|
- BUG_BRACQUOT: shell quoting within bracket patterns has no effect. This
|
|
bug means the '-' retains it special meaning of 'character range', and an
|
|
initial ! (and, on some shells, ^) retains the meaning of negation, even
|
|
in quoted strings within bracket patterns, including quoted variables.
|
|
|
|
- BUG_IFSGLOBS: In glob pattern matching (as in case or parameter
|
|
substitution with # and %), if IFS starts with ? or * and the "$*"
|
|
parameter expansion inserts any IFS separator characters, those characters
|
|
are erroneously interpreted as wildcards when quoted "$*" is used as the
|
|
glob pattern.
