• 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 ☺
this change broke abortion on failure to read input, was not
needed for gcc warnings and is the fault of Intel’s compiler
this should fix the other busy-loop problem occuring only on
GNU/Linux so far – 10x spaetzle@freewrt.o for pointing me to
the problem; reproduced on my work craptop
from netbsd via oksh
we had the NULL pointer deref already fixed
• avoid a bogus not-setting the return value of edit.c:x_file_glob()
introduced by the above change in oksh
• escape ? as well (but not ] because that’s wrong)
reminded by cbiere@netbsd via oksh
• Unsetting a non-existent variable is not an error. See
http://www.opengroup.org/onlinepubs/009695399/utilities/unset.html
report from Arkadiusz Miskiewicz; fixed based on
http://cvs.pld-linux.org diff via oksh but modified slightly
• Be more smart waiting for input for non-interactive scripts. Fix
based on a diff from debian: see their bug#296446 (via oksh)
modified slightly
this also fixes cnuke@’s “mksh busy loop” problem, for which I never
received a bug report, but the Debian bug page contains a set of two
scripts to reproduce this before (and no longer after) this commit
• some KNF
• bump version
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.
problems. icc's warnings are bogus:
• it says int x_getc(void); is invalid (hm well, it may be static?)
• char c, d; d = c | 0x40; -> warning because (c | 0x40) is an int
(it apparently can't track value bounds)
(by dramsey again, you're DA MAN) by replicating some of the x_redraw() logic
Note that this is correct, a construct like the full-fledged
| x_e_putc2((xep > xlp) ? ((xbp > xbuf) ? '*' : '>') : (xbp > xbuf) ? '<' : ' ');
is not needed since if (xep > xlp) && (xbp > xbuf) – i.e. in the '*' case –
x_redraw() will be called anyway and because (xx_cols - 2 - x_col) == 0 the
code won't be triggered.

this one was harder to track down, additional variables coming into the play…

tested to not slow down _even_ more a 75 MHz sparc (neko.haemoglobin.org)
thanks to dramsey again for testing
Analysis:
internal_errorf(int, fmt, ...) was only a __dead function if the int argument
was non-0, which the Prevent probably was unable to follow. Change all uses of
internal_errorf(0, fmt, ...) to internal_warningf(fmt, ...); change the pro-
totype of internal_errorf() to internal_errorf(fmt, ...) and all remaining
uses remove the non-0 int argument; add __dead to internal_errorf() proto;
flesh out guts of internal_errorf() and internal_warningf() into a new local
function for optimisation purposes.
Some whitespace cleanup and dead code removal (return after internal_errorf(1))
• if it's in x_literal() (“quote” / ^V) mode, it's accepted like now
• if it's a mb sequence start, it's rejected with a beep
• if it's a mb continuation, the whole sequence is silently rejected
this makes command line editing when accidentally hitting, e.g. with
my mircvs://contrib/samples/dot.Xmodmap, Mode_switch-x much more ro-
bust.
the same as ASCII control characters (U+0001..U+001F), i.e. with a ctrl ca-
ret and its value XOR U+0040; treat their width as 2
fixes crash+cpu hog on 'meta-tab backspace'
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
sequence is eaten before the command is called; cought by <TGEN>
(Thomas E. Spanjaard) via IRC
fix is to tabcomplete a newline to singlequote+newline+singlequote
* bump version
actually within a (the emacs) editing mode does not work at
all, whether forced or not, only if we leave the editing mode
(at end of input); probably due to it saving stuff from e.g.
x_cols into xx_cols, etc.
-> remove SIGWINCH handling(!)
-> TIOCGWINSZ is now executed at end of every input line
-> use 'ESC #' if you direly need to change line size
only if we got a SIGWINCH -> interactive use speed-up on the
slower boxen (slowness courtesy of otto@obsd)
* ^L (redraw line) now (always) checks window size; use this
instead if required while editing the prompt; changes to the
variables will still be propagated after the line is entered
