Patch from current ksh93 maintainer <https://github.com/ksh93/ksh>. cde/programs/dtksh/ksh93/**: - Upgraded. A load of bugs fixed, some minor features added. See NEWS from 2021-02-01 upwards. cde/programs/dtksh/Makefile.am: - Don't cd into ksh93 any more to invoke the package or shtests scripts; they now automatically find their directories. - Pass $(CFLAGS) to build ksh with optimisation. - Remove -D_std_malloc flag as vmalloc is now deprecated and disabled by default. - Add a 'make check' target to Makefile.am that runs the ksh93 regression tests on dtksh to make sure the additions don't interfere with anything. It skips running the tests with shcomp because CDE doesn't use that. The tests all pass here on Slackware 14.2. :-) cde/programs/dtksh/init.patch: - Removed; I've upstreamed it. It was the only one that wasn't upstreamed yet, and more code cleanups are coming, breaking downstream patches. If something needs updating, just email me a diff. cde/programs/dtksh/dtkcmds.h: - Update the ADDBUILTIN macro to remove the __PROTO__ macro use. The proto(1) tool, responsible for all such pre-C89 K&R C compatibility voodoo, has been removed, so that macro is no longer defined. cde/programs/dtksh/setup.sh: - Workaround script removed. I rewrote 'bin/package flat make' in a way that works correctly and changed Makefile.am to use that instead. Hope this helps. Happy new year.

Fix regression test failures:
|
|
|
|
- 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.
