tg bb51eee63c when doing tab completion partial inserts in UTFMODE, honour multibyte character boundaries (LP: #909025) 2011-12-29 23:36:10 +00:00
tg 4748739523 eek, mira, don’t leave debugging code lying around 2011-12-11 18:07:45 +00:00
tg 986d999e58 make ^O work like it did before we introduced x_modified(), that is,
editing the refetched input line doesn’t let it restart (but ^R does)

tg 44d072a879 beautify a Vi function (no code change), from tech@ discussion 2011-12-04 23:22:59 +00:00
tg 23afb6dbb8 merge “upper bound Emacs mode command repeat by input line length” from
oksh (slightly different implementation) and remark better plans (which
doesn’t mean bounding the repeat counter is bad, though…)

tg 9782f6b4d1 • access(2) is broken in at least kFreeBSD 9.0 as “modern” OS, so bring
back the wrapper code as well as refactor most other code calling it
• apparently, names can’t end in ‘_’ or contain ‘__’ anywhere…

tg 577c918beb patch most of Jerker Bäck’s concerns out, unless not applicable 2011-08-27 18:06:52 +00:00
tg ac814611f1 somebody (who is probably inlining) complains about memset with the
third argument being 0; maybe (I think can only be this) fix that

tg 0785c2d71c fix tab completion of "~/M↹" 2011-07-02 17:57:12 +00:00
tg 257021e510 fix, even removing code, good… 2011-06-30 14:09:04 +00:00

tg e0a913181b fix regression found by hondza: the full path was shown when tab-completing 2011-06-04 15:11:29 +00:00
tg bef346b938 we use tobool() nowadays 2011-06-04 15:06:50 +00:00
tg 2cfc3e5c3d mksh R40 Release Candidate 1
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

tg d72669c66b this one is trickier 2011-04-22 12:16:38 +00:00
tg 6c0255ecb2 more static initialisers (verified using nm comparision between mksh
built with/-out "-ffunction-sections -fdata-sections -Wl,--gc-sections"
2011-04-22 12:15:42 +00:00
tg c0e1e7645a static initialisers implicitly null out a variable (I think)
so take care of that (for global variables) to avoid them
moving from .bss to .data
2011-04-22 12:10:14 +00:00
tg 6c45e3e764 avoid namespace conflicts with __attribute__(…) 2011-04-09 21:01:03 +00:00
tg b7824978ad RCSID sync with openbsd, one we had already, one Okan Demirmen stole
from mksh (but attributed, so it’s okay, considering the amount of
patch is not large enough to warrant copyright stuff)

tg 2a3d4db123 lint is your friend 2011-03-13 01:20:25 +00:00
tg 5f8075fc82 introduce a tobool(cond) abstraction¹ and switch bool to char if !stdbool.h
① currently: ((cond) ? true : false) but (!!(cond)) and casting to bool,
  the latter only if stdbool.h, would also work – which performs best on
  (and across) all supported systems?

tg 4e0f597b5d fix prev-hist-word again, thanks Jörg-Volker Peetz 2011-02-09 13:08:18 +00:00
tg d4658a569e refactor code to be able to track whether we have a parameter substitution
or a “proper” glob expansion; if there’s a dollar, but not a glob, refrain
from appending a space later (LP: #710539)
2011-02-03 15:57:52 +00:00
tg 9b02e15d26 For prev-hist-word, when doing other things in between reset the counter 2011-01-21 22:43:17 +00:00
tg 667d792d6a • Address concerns of Chris Palmer from the Android security team
– possible integer overflows in memory allocation, mostly
    ‣ multiplication: all are checked now
    ‣ addition: reviewed them, most were “proven” or guessed to be
      “almost” impossible to run over (e.g. when we have a string
      whose length is taken it is assumed that the length will be
      more than only a few bytes below SIZE_MAX, since code and
      stack have to fit); some are checked now (e.g. when one of
      the summands is an off_t); most of the unchecked ones are
      annotated now
    ⇒ cost (MirBSD/i386 static): +76 .text
    ⇒ cost (Debian sid/i386): +779 .text  -4 .data
  – on Linux targets, setuid() setresuid() setresgid() can fail
    with EAGAIN; check for that and, if so, warn once and retry
    infinitely (other targets to be added later once we know that
    they are “insane”)
    ⇒ cost (Debian sid/i386): +192 .text (includes .rodata)
• setmode.c: Do overflow checking for realloc() too; switch back
  from calloc() to a checked malloc() for simplification while there
• define -DIN_MKSH and let setmode.c look a tad nicer while here
2010-09-14 21:26:19 +00:00
tg 56a69907d5 optimise error messages, option parsing, and make more builtins
recognise "--", costs us 20 .text 0 .data 0 .bss
2010-09-05 19:51:35 +00:00
tg 06c6be0a70 shave off another 468 bytes: we’re 300 bytes smaller than BEFORE the
cat builtin was added now… (also removed utf-8 from source files, in
favour of just ASCII)
2010-08-28 20:22:24 +00:00
tg 3747722db4 improve string pooling: saves 316 bytes in .text 2010-08-28 18:50:58 +00:00
tg 297e2ced89 fix blocking_read prototype 2010-08-28 16:47:11 +00:00
tg c187f3089f a tad annoying, when external programmes such as GNU screen are running,
we don’t get SIGWINCH when the window size changes during the runtime of
that, so, the signal is only usable reliably during editing in the shell
and we re-check the window size before each interactive edit line again
2010-07-25 11:35:43 +00:00
tg 7c91e018f4 • merge printf from OpenBSD
• deactivate %a and %A since our libc doesn’t have it
• rewrite the mksh integration code to use shf instead of stdio, removing
  floating point support always in the process, as shf doesn’t support it
  ⇒ saves 11114 (6706 text, 168 data, 4240 bss) with dietlibc on Debian
• fix -Wall -Wextra -Wformat -Wstrict-aliasing=2 for gcc (Debian 4.4.4-7)
• fix these and -Wc++-compat for gcc version 4.6.0 20100711 (experimental)
  [trunk revision 162057] (Debian 20100711-1) except:
  – a few enum warnings that relate to eglibc’s {g,s}etrlimit() functions
    taking an enum instead of an int because they’re too stupid to adhere
    to POSIX interfaces they design by themselves
  – all “request for implicit conversion” involving a "void *" on one side
• tweak the manual page somewhat more

tg 31b288561f this one was found by scan-build from llvm+clang 2010-07-04 18:52:52 +00:00
tg 30046ffcf2 implement “live” SIGWINCH handling in the Emacs editing mode
for winstonw from IRC #!/bin/mksh
2010-07-04 17:45:17 +00:00
tg 2a72f0e2f0 RCSID sync with oksh, and apply a simplification of theirs, but WITH a
comment what/why added (to aid understanding this code)

I wonder, though, why their x_escape now almost¹ looks like ours… is
that a coïncidence, or do they steal again (without understanding why)?

① they’re missing the semicolon but falsely added the closing bracket
2010-05-22 12:37:49 +00:00
tg c00f87bdb3 Let hi-bit7 characters be “motion characters” for the Emacs editing mode;
this fixes the asymmetry of Esc+b/Esc+f on 「ls ディレクトリ」 as well as
doing ^W on it
2010-03-27 15:26:19 +00:00
tg 150a35a02d x_bind cannot have the nonnull attribute
cought by Frank “enstein” Terbeck «ft:#grml» (efftee), 10x

tg 4eb17f8752 remove some more of this ugliness 2010-01-29 09:34:31 +00:00
tg 833810a154 While we were supposed to use Ctrl-Arrowkey for wordwise jumping,
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)
2010-01-08 22:21:06 +00:00
tg 769e222586 re-vamp __attribute__ handling; let this pass on HP-UX bundled compiler
as well as HP aCC

tg 8213a28403 llvm/clang scan-build is now content… 2009-12-05 17:43:50 +00:00
tg 6fcacf577d make tab completing filenames with ':' '=' '$' '`' work as well as
others (colon and equals sign need to be simply escaped, while dollar
sign and accent gravis need double escaping like opening square brak-
ket did back then); add = to C_QUOTE to simplify (doesn't break any-
thing) and sort these strings asciibetically while here
2009-10-30 00:57:39 +00:00
tg 7b7b75b026 * move the utf_* functions to a smaller file, to reduce the pain the
CPU has to endure while gcc is crunching on edit.c
* comment on mksh not using _exactly_ OPTU-8/OPTU-16 (XXX)
2009-09-26 04:01:34 +00:00
tg 1dfb13b603 change undef/def MKSH_NOVI into 0/1 MKSH_S_NOVI flag (with more to come:
MKSH_S_EDIT for small (Emacs) editing mode, MKSH_S_FEAT for all the dis-
abled language features), which can be set to 0 despite MKSH_SMALL being
defined to re-enable the Vi command line editing mode (which I wouldn't,
but fits into the general mastermind scheme)
2009-09-24 17:15:33 +00:00
tg 1a28786229 * shrink MKSH_SMALL even further by removing functionality like
some GNU bash extensions (suggested by cnuke@) and bind macros
* make the random cache more efficient (and the code potentially
  smaller, although we have a new implementation of the oaat hash
  function, alongside the old one, now) and pushb only if needed
  (i.e. state has changed or user has set $RANDOM, but not onfork)
2009-09-23 18:04:58 +00:00
tg 1ea1096a4e Add a hack input function for VT100-style key sequences; support
Ctrl-CurLeft and Ctrl-CurRight (not quite ANSI, but fits the scheme)
2009-09-20 17:23:52 +00:00
tg 08ec9ca3ab fix (another… *sigh*) inverse logic error 2009-09-20 17:18:53 +00:00
tg 2ef07a6cc9 shrink MKSH_SMALL by removing certain editor functionality (e.g. the tilde
hack) and functions (up/down/titlecase words; search history PgUp/PgDn)
2009-09-20 17:00:53 +00:00
tg 0cf2df79e9 if things need to be in a specific order, use automated means to provide
such order, instead of relying on manually retaining it…
