6b00977053 just another oksh rcsid-only sync (we bind to the Delete key since forever) 2015-04-11 22:09:49 +00:00

532af35304 oksh rcsid sync; we have no set -o csh-history, and the manpage changes are just wrong, so, a nop 2015-03-14 05:17:17 +00:00

2f52b993a1 • Build.sh: fix NSIG detection for gcc-snapshot 
• all: bump version to R50-current; add more comments; whitespace
• all: remove all mkssert(); we’ll do full re-runs of scan-build and,
  hopefully, Coverity Scan/Prevent
• check.t: fix a testcase (sed could exit false, but we don’t care)
• eval.c: fix tilde_ok data type (only unsigned may shl constantly)
• exec.c: fix shebang buf array accesses to always go via uint8_t *

0d9b36daa3 prototype for a static function used before it’s defined 
XXX add protos for all static functions (just: hard to find them)

0432fc1a87 Get rid of left over NULL elements in x_ftab as NELEM() is used instead. 
From Martin Natano. Also get rid of related checks.

89e774fd7e • fix ${12345678901234567890} segfault (OOB access / integer overflow) 
‣ not like oksh did, but using mksh’s built-in features
• handle suggested __pure additions
• revert cid 1004F7F096867C83CF0
  ‣ always use our wcwidth code
  ‣ only use our strlcpy code if none found
• fix a couple of gcc-snapshot and clang/scan-build warnings
• mksh R49~rc1

2f7eec765d merge oksh’s “ctype cleanups” commit 
(not much of it applies since we don’t use the OS’ table-based lookup)

c4c4fd7365 RCSID-only oksh sync (their whitespace changes don’t apply to us) 
note that emacs.c partial peereboom rewrite is *not* merged, and kept that way

7f16464902 slightly optimised and, more importantly, much more consistent (use only 
one set of CTRL, UNCTRL, and new ISCTRL macros) C0 and DEL handling; the
optimisation only works for 7-bit ASCII, so those places 8-bit must pass
intact have an added check

also, while here, remove an editor oops (‘;’), oksh rcsid sync (they did
accept I was right wrt. set -e), int → bool, and code merge/cleanup

5eb6995d75 Ypnose discovered a problem with multi-line prompts and SIGWINCH 
related to caching some values (downside, pprompt gets back doprint option)

bf94b7e2ec fun: when writing this code I feared an off-by-one; 
Steffen Daode Nurpmeso stumbled upon it and gave very detailed
instructions on how to reproduce it (thanks!); fix that

also only call x_bs0 if xcp < xep because *xep is undefined

c10e5bd237 reduce amount of .bss memory needed; initialise via AEDIT at x_init

247e20c524 • Completely overhaul prompt length calculation and 
prompt display routines; make Emacs and Vi share
  code, permitting reducing of duplication and code
  removal as well as more consistent behaviour; put
  some common code into shared helper functions, too
• New x_adjust() logic (Emacs mode): when determining
  what portion of a line to render use a much more
  sophisticated algorithm and try to fill up ⅔ of the
  total screen width (with line and prompt both) also
  as wished from Steffen Daode Nurpmeso

b58d7b8053 fix regression wrt. pdksh (introduced between R40e and R40f) 
about how and when the display is redrawn by reverting one
bool back to an int, as it’s used as a counter (hm, should
be an unsigned I guess but…)

on the other hand, xlp_valid should’ve been a bool, make it so

1f43cc907d fix backslash-asterisk glob noise for nōn-existant targets and tilde 
expansion completion; problem analysis and solution draft by Andrew
Kudryashov (thanks a lot!); this fix instead re-uses existing code
for solving the problem with multiple matches

debugged using “make d dr” targets, yay!

9fbdef8e60 pure RCSID sync with OpenBSD, as we introduced SIGWINCH tracking earlier 
XXX we could track whether tty_fd has already been successfully opened,
XXX the ttystate initialised, and then just never close it unless it is
XXX necessary, then we can keep COLUMNS/LINES accurate in scripts, even

4778a2a62f lesson learned from http://k1024.org/~iusty/blog/entry/perf-null/ – add -DMKSH_SMALL_BUT_FAST which gives more speed (8/20K less cycles, 5/9K less insns, 1.8/2.4k less branches, 65/275 less branch misses) on Debian/amd64 (klibc-static/eglibc) at cost of 0/2 more page faults and 6K/6K more text size 2012-07-01 15:55:00 +00:00
