Testsuite:
• add new need-pass: {yes|no} attribute, default yes
• exit with 1 if a need-pass test failed unexpectedly
idea by Kacper Kornet <draenog@pld-linux.org>
• mark utf8bom-2 as need-pass: no
Infrstructure:
• add housekeeping function for making a tty raw
• switch functions with unused results to void
• struct op: u.charflag contains last char of ;; in TPAT
• var.c:arraysearch is now a global function
Language:
• add ;& (fall through) and ;| (examine next) delimiters
in addition to ;; (end case) as zsh extensions, because
POSIX standardised on ;& already
• add -A (read into array), -N (read exactly n bytes),
-n (read up to n bytes), -t (timeout) flags for read
from ksh93
• allow read -N -1 or -n -1 to slurp the entire input
• add -a (read into array the input characters) extension
specific to mksh to read, idea by David Korn
• add -e (exit with error if PWD was not set correctly
after a physical cd) to cd builtin, mandated by next
POSIX, and change error codes accordingly
Rewrites:
• full rewrite of read builtin and its manpage section
• add regression tetss for most of the new functionality
• duplicate hexdump demo tests for use of read -a
• use read -raN-1 in dot.mkshrc to get NUL safe base64,
DJB cdb hash and Jenkins one-at-a-time hash functions
add most of the mksh wtf edition dot.mkshrc patch, some commented
out; optimise some other cases (e.g. don't reset MKSH if set, don't
export already exported variables, etc.)
• ensure unsigned arithmetics is used in the cdb hash
• make the hash functions print their result again
• now we can use the Lb64{en,de}code trick of using stdin if "$*"==""
• optimise the one-at-a-time code for shell
fix the regression test’s results while here, which have been
broken since cid 10049D9BE5254CE65B8
• get rid of separate copyright file which was intended for De-
bian; track down commits in all files of oksh-mirbsd and mksh
to get correct copyright years per-file, as is BSD custom
strip it, but that might have other problems, better is to use realpath(2),
e.g. via readlink(1), for normalisation, or have the sysop fix it)
XXX make realpath a builtin?
* 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 $USER_ID changes in mksh (speed-up here, too)
mksh.hts:
* sync changelog
‣ now, a “ksh93” just requires ‘function precmd { :; }; set -o emacs’
afterwards to get rid of the annoying error messages
‣ I could lose that with the following idiom:
- PS1='$(precmd)…
+ PS1='$(typeset -i e=$?; typeset -f precmd >&- && { (return $e); precmd })…
but it didn’t seem worthwhile to me
• remove explicit licence blah, normal ./copyright applies
running it on “~/.” (must be a directory) in a global readonly variable
• if readlink fails, use some more or less sane values (no idea what csh(1)
does in these cases, maybe some feedback here?)
• optimise, while here
• dirs, pushd, popd like ports/shells/csh (Berkeley C shell)
• precmd, chpwd like ports/shells/zsh (Z shell)
and implement keeping ${DIRSTACK[0]} up to date via chpwd()
instead of doing it on entry of pushd and dirs (so that it
can be used directly)
this is slow compared to earlier, but people seem to want it
we already do not 'function\nfoo\n{' for shell, like style(9) requires for
C programming, but 'function foo\n{' instead. however, we could treat the
function keyword as indentation initialiser and use 'function foo {' (on a
line for itself) – it looks different, unusual, but acceptable, and mksh's
own output (dumping with the “functions” builtin) does that too (although,
its indentation style sucks, but is legible enough)
place most stuff from /etc/profile in /etc/skel/.mkshrc; admins must make
sure to copy this file to users' homes on upgrade (benefit: non-login but
interactive shells also get all the goodies); fix some quoting; simplify,
reformat, change comments
• from an mksh point of view:
slight internal changes in dot.mkshrc; external commands are now prefixed
with “ulimit -c 0”; $TERM is defined; improvement in determining the host
name (e.g. on Debian if a FQDN is not given); declare locals as such both
in $PS1 and outside; remove superfluous quoting, quote properly; simplify
hd alias, add rot13 alias; place RCS ID at the bottom
and have it return an API-correct const char *
• enhance and stylify comments
• a little KNF and simplifications
• #ifdef DEBUG: replace strchr and strstr with ucstrchr and ucstrstr
that take and return a non-const char *, and fix the violations
• new cstrchr, cstrstr (take and give const char *)
• new vstrchr, vstrstr (take const or not, give boolean value)
• new afreechk(x) = afreechv(x,x) = if (x1) afree(x2, ATEMP)
• new ksh_isdash(str) = (str != NULL) && !strcmp(str, "-")
• replace the only use of strrchr with inlined code to shrink
• minor man page fixes
• Minix 3 signames are autogenerated with gcc
• rename strlfun.c to strlcpy.c since we don't do strlcat(3) anyway,
only strlcpy(3), and shorten it
• dot.mkshrc: move MKSH=… down to the export line
to not disturb the PS1 visual impression ☺
• dot.mkshrc: Lstripcom(): optimise
• bump version
¹) side effect from creating API-correct cstrchr, cstrstr, etc.
uses goto so it must be better ☻
tested on mirbsd-current via both Makefile and Build.sh
of a pipeline is executed in a subshell' trick, don't use co-process
(because that's verbose twice in an interactive shell profile), move
the noglob block into the while and rid the redundant +o and local.
* sync dot.mkshrc sample with FreeWRT r383
* add some stuff from src/etc/profile and contrib/samples/etc_profile
* sync the latter two with reality and shorten
* teach the user in the mksh installation instructions to install the sample
NB: the sample is also covered by the MirOS licence
