TODO for AT&T ksh93, 93u+m bugfix branch
|
||
|
||
______
|
||
Fix regression test failures:
|
||
|
||
- On OpenBSD, there are 15 locale-related test failures in variables.sh.
|
||
|
||
______
|
||
Fix build system:
|
||
|
||
- ksh does not currently build on NetBSD, AIX, Solaris, or QNX.
|
||
- Reimport the removed nmake. It is necessary for changes in Makefiles
|
||
to take effect. The machine-generated Mamfiles are now used as a fallback,
|
||
but they are not meant to be edited by hand.
|
||
|
||
______
|
||
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_CMDEXPAN: if the 'command' command results from an expansion, it acts
|
||
like 'command -v', showing the path of the command instead of executing it.
|
||
For example:
|
||
v=command; "$v" ls
|
||
or
|
||
set -- command ls; "$@"
|
||
don't work.
|
||
See also: https://github.com/att/ast/issues/963
|
||
|
||
- BUG_CMDSPEXIT: preceding a "special builtin"[*] (other than 'eval', 'exec',
|
||
'return' or 'exit') with 'command' does not always stop it from exiting
|
||
the shell if the builtin encounters error.
|
||
[*] https://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_14
|
||
|
||
- BUG_CSUBSTDO: If standard output (file descriptor 1) is closed before
|
||
entering a $(command substitution), and any other file descriptors are
|
||
redirected within the command substitution, commands such as 'echo' will
|
||
not work within the command substitution, acting as if standard output is
|
||
still closed.
|
||
|
||
- BUG_IFSGLOBS: In glob pattern matching (as in case or parameter
|
||
substitution with # and %), if IFS starts with ? or * and the "$*"
|
||
parameter expansion inserts any IFS separator characters, those characters
|
||
are erroneously interpreted as wildcards when quoted "$*" is used as the
|
||
glob pattern.
|
||
|
||
- BUG_LOOPRET2: If a 'return' command is given without a status argument
|
||
within the set of conditional commands in a 'while' or 'until' loop (i.e.,
|
||
between 'while'/'until' and 'do'), the exit status passed down from the
|
||
previous command is ignored and the function returns with status 0
|
||
instead.
|
||
|
||
- BUG_MULTIBIFS: We're on a UTF-8 locale and the shell supports UTF-8
|
||
characters in general (i.e. we don't have WRN_MULTIBYTE) – however, using
|
||
multi-byte characters as IFS field delimiters still doesn't work. For
|
||
example, "$*" joins positional parameters on the first byte of IFS instead
|
||
of the first character.
