Release 1.0.0-beta.1 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.

TODO for ksh 93u+m

**/Mamfile: Use IFFEFLAGS variable to add iffe flags like -d1 It was unreasonably hard to debug problems with iffe tests that fail to compile where they should (particularly output{ ... }end blocks that write esserntial headers). In e72543a9 the problem was already somewhat mitigated by making some of the failing output{ ... }end blocks emit #error directives so that invalid/incomplete headers would cause an error at a sensible point, and not a much harder to track error later. This commit further mitigates the problem by making the Mamfiles respect an IFFEFLAGS environmenet variable that is prefixed to every iffe command's arguments. The typical use would be to export IFFEFLAGS=-d1 to enable debug level 1: show compiler output for all iffe tests. This now makes it reasonably feasible to detect problems in the feature tests themselves. src/**/Mamfile: - Import IFFEFLAGS environment variable using setv. - Prefix ${IFFEFLAGS} to every iffe command. src/**/features/*: - Amend the new fail error messages to recommend exporting IFFEFLAGS=-d1 to show the cause of the failure. README.md, TODO: - Updates.

https://github.com/ksh93/ksh/issues/182
* typeset -L/-R: string length breaks on multibyte characters
https://github.com/ksh93/ksh/issues/189
* Linux i386: variable expansion corruption in single-line function
https://github.com/ksh93/ksh/issues/203
* Segfault with very large extended glob patterns
https://github.com/ksh93/ksh/issues/207

https://github.com/ksh93/ksh/issues/231
* Freeze/crash on OpenBSD with -D_std_malloc involving typeset and command
substitution
https://github.com/ksh93/ksh/issues/264

https://github.com/ksh93/ksh/issues/269
Enhancements to do:

https://github.com/ksh93/ksh/issues/123
* Add -T (-o functrace) option as in bash
https://github.com/ksh93/ksh/issues/162

https://github.com/ksh93/ksh/issues/193
* Re-allow building dynamic libraries
https://github.com/ksh93/ksh/issues/302
INIT/cc.darwin: re-suppress redefined macro warnings (re: a1d8ff6f) Allowing redefined macro warnings was not such a good idea, as the Apple compiler flags redefine the _ast_int8_t macro right on the command line, producing a warning for every cc invocation. (cherry picked from commit 929930224f898cb1371471fe554fabb73b31d11f)

______
Fix regression test failures:
Top-level documentation tweaks LICENSE.md: - Fix Markdown formatting of headers. README.md: - Add coding style note about opening braces. TODO: - Add note about OpenBSD regress test failures.
2021-02-20 23:19:50 +00:00
- 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.
