‣ only if !MKSH_SMALL
‣ add appropriate regression test
• if FPOSIX is set, do not close fds > 2 on exec, Debian #499139
• add appropriate regression tests for keeping fds private or not
developers, I understand about 1% of the source code only) yet still
functional (just not en par with the emacs editing mode, but no known
regressions over oksh (in -current) and better functionality than most
other korn shells, according to Yofuh)
and make it fit into mksh’s model (also gives us a couple of things
GNU bash doesn’t have
• add regression tests for all of these
Lukas “smultron” Upton from MidnightBSD spotted a script with /bin/sh
shebang invalidly using “&>” in some Apple backup toolkit, 10x
XXX why fds are limited to one digit?
* initialise the integers PPID, OPTIND, RANDOM, SECONDS, and TMOUT to base-10
* bring back PGRP as base-10 integer to the process group via getpgrp(2)
* initialise USER_ID as base-10 integer to the effective user id as retrieved
from geteuid(2) = $(id -u)
* use $USER_ID in dot.mkshrc instead of spawning an id(1) process
-> dot.mkshrc,v 1.34 now requires mksh R34
* convert more int to bool where appropriate
* remove dead code - getpgrp(2) cannot fail
* sync manual page to reality
* bump to mksh R34(beta) - feature freeze
XXX check if our_pgrp in jobs.c is still really needed, the setpgid call
XXX probably just makes us our own pgrp leader, and we might have to use
XXX and update kshpgrp accordingly - need feedback/help here but I think
XXX this simplification should be possible if I grok the code correctly.
etc/profile:
* adjust to $USER_ID changes in mksh (speed-up here, too)
mksh.hts:
* sync changelog
• more int → bool
• more regression tests: check if the utf8-hack flag is really disabled
at non-interactive startup, enabled at interactive startup, if the
current locale is a UTF-8 one
• make the mksh-local multibyte handling functions globally accessible,
change their names, syntax and semantics a little (XXX more work needed)
• optimise
• utf_wctomb: src → dst, as we’re writing to that char array (pasto?)
• edit.c:x_e_getmbc(): if the second byte of a 2- or 3-byte multibyte
sequence is invalid utf-8, ungetc it (not possible for the 3rd byte yet)
• edit.c:x_zotc3(): easier (and faster) handling of UTF-8
• implement, document and test for base-1 numbers: they just get the
ASCII (8-bit) or Unicode (UTF-8) value of the octet(s) after the ‘1#’,
or do the same as print \x## or \u#### (depending on the utf8-hack flag),
plus support the PUA assignment of EF80‥EFFF for the MirBSD encoding “hack”
(print doesn’t, as it has \x## and \u#### to distinguish, but we cannot use
base-0 numbers which I had planned to use for raw octets first, as they are
used internally): http://thread.gmane.org/gmane.os.miros.general/7938
• as an application example, add a hexdumper to the regression tests ☺
(3 weeks, 5 days ago) by millert
Make ulimit able to get and set multiple limits in a single invocation
like bash and zsh do. Requested by espie@, OK deraadt@
matches mksh pre-R29 (the one introducing the bug), and typeset matches
the behaviour intended with the R29 changes (better AT&T ksh93 compati-
bility) but never reached
• adjust the man page description of “typeset -p”, as it’s different from
the “typeset” and “typeset -” actions
| csh -cf '/command/svscanboot &'
and
| /usr/mpkg/bin/pgrphack /usr/mpkg/bin/svscanboot &
can now be replaced with
| /bin/mksh -T- /usr/mpkg/bin/svscanboot
with GNU groff – add some special handling to the BSD mdoc macros for it so
that the manual pages look good in both utf8 and ps (PDF) mode; also fix in
mksh wrong display of ` (groff: ‘), ' (groff: ’), \' (groff: ´), \- (groff:
U+2212 −), the en dash (nroff doesn’t have it, use the em dash there ONLY),
and ~ and ^ (groff: placed atop and size-reduced, for use as diacritics, in
manual pages bad since these are control characters there)
→ PDF manpage now has ‘’ “” and good-looking hyphens and mini and ~ and ^
→ utf8 manpage now has ‘’ “”, good-looking hyphens, cut’n’pasteable mini
→ nroff manpage still has '' "" instead of ugly `' ``'' or even `´
→ Debian lintian won’t complain any longer
me, which points out that “gnroff -Tutf8” mangles the ‘-’ characters
(hyphen/minus) from the input into ‘‐’ characters (hyphen), which does
not make sense in many cases and prevent copy’n’paste → fix
no change in nrcon output
In contrast to AT&T ksh93, its semantics are like GNU bash in that it ap-
pends the current working directory to the search path; it is implemented
as a shell alias instead of enhancing funcs.c:shbuiltins[] like in ksh93.
so that archite@midnightbsd won’t have to add evil kludges to oksh again if
they switch their ksh to mksh ☺
both “clear-screen” and “error” aren’t bound; default binding for ^L stays,
as usual, “redraw” (principle of least surprise); however GNU bash converts
also might want to put “bind ^L=clear-screen” into their ~/.mkshrc.
namely Dr. Robert “Pfeffer” Arnold (in this case, in FreeWRT), make
a half-completed attempt at implementing ${foo:2:3} substring evals
(of course, negatives can't work right now and that the numbers are
in face expressions is something I only read later too – this is to
be revisited later, but it's already late)
don't depend on this behaviour yet though
if someone wants to add more regression tests, feel free to…
is a compromise anyway; these lunox people will have to live with that, too
many existing korn shell alike scripts depend on it even if not on the full
korn shell syntax availability (note: this doesn't mean using these in some
script with #!/bin/sh is ok)
