and vendor pdksh versions, re-introduce FPOSIX alongside FSH. The semantics
are now:
‣ set -o posix ⇒
• disable brace expansion and FSH when triggered
• use Debian Policy 10.4 compliant non-XSI “echo” builtin
• do not keep file descriptors > 2 to ksh
‣ set -o sh ⇒
• set automatically #ifdef MKSH_BINSHREDUCED
• disable brace expansion and FPOSIX when triggered
• use Debian Policy 10.4 compliant non-XSI “echo” builtin
• do not keep file descriptors > 2 to ksh
• trigger MKSH_MIDNIGHTBSD01ASH_COMPAT mode if compiled in
• make “set -- $(getopt ab:c "$@")” construct work
Note that the set/getopt one used to behave POSIXly only with FSH or
FPOSIX (depending on the mksh version) set and Bourne-ish with it not
set, so this changes default mksh behaviour to POSIX!
(I think this is because the TAND and the Job are not visible to
the code at the same time; patches welcome, as usual)
I don't think this is related to ^Z'd systrace(1)'d programmes
sometimes being unawakable, though.
concurrently accessing the same $HISTFILE be more synchronised with
each other: empty lines (just pressing Return) and duplicates (that
are split and written twice by the lines loaded from $HISTFILE in
the meantime); requested by Maximilian “mxey” Gaß in #!/bin/mksh
of foo[0] (but not its attributes), and the rest of the array, so that
later “set +A foo bar” will set foo[0]=bar but retain the attributes.
This is important, because, in the future, arrays will have different
attributes per element, instead of all the same (which, actually, is
not entirely true right now either, since “unset foo[0]” will not mo-
dify the attributes of a foo[1] existing at that point in time), where
foo[$newkey] will inherit from foo[0], but typeset foo will only affect
foo[0] no longer foo[*] in the future. (The rules about typeset=local
will still apply, as they affect creation of variables in a scope.)
some idiotic terminal emulators and/or people seem to use the es-
cape codes normally denoting Alt-Arrowkey instead so let's simply
bind them to the vt_hack as well... (untested)
• merge the rest of branch tg-wcswidth-behaviour
• enhance test cases for wcswidth-like behaviour
• switch hash table collision resolution algorithm to Python’s as announced
• bump vsn
which, in its latest sid incarnation, even received mksh's ability
to produce ${!foo[*]} array keys, wow!)
* plug a memory leak while here (ATEMP only, but still)
• use a combination of the one-at-a-time hash and an LCG for handling
the $RANDOM special if !HAVE_ARC4RANDOM instead of rand(3)/srand(3)
and get rid of time(3) usage to reduce import footprint
• raise entropy state (mostly in the !HAVE_ARC4RANDOM case though…)
• simplify handling of the $RANDOM_SPECIAL generally
• tweak hash() to save a temp var for non-optimising compilers
• some int → mksh_ari_t and other type fixes
• general tweaking of code and comments
just a "somewhat more POSIX" but also a "/bin/sh legacy kludge" mode
* consistently capitalise POSIX and SUSv3/SUSv4 (same as AT&T ksh) and
Bourne shell
to it are now either arc4random or rand/srand, but srand retains the old
state; set +o arc4random is no longer possible, but if it's there we use
arc4random(3), if not, we use rand(3) for $RANDOM reads; optimise special
variable handling too and fix a few consts and other minor things
• shell flags are now handled in one single place (sh_flags.h)
• sync comments (between enum and array) and manpage with reality
• FMONITOR is now no longer needed for Hartz IV shells
integers in addition to my 「1#a」 (or 「1#…」), which also allows for
finer end-of-character checking. Note that this is locale-dependent in
ksh93, set ±U dependent in mksh, and mksh’s OPTU-16 encoding is used.
