- ______
- 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.
