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 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 c38dfbf51a fix problem #1 and a comment 2011-05-07 00:24:35 +00:00
tg c021aa4cad • use a flag for determining here strings, don’t parse delimiter every time
• don’t leak memory parsing possible I/O redirection tokens
• get rid of volatile by using more const (also helps codegen, methinks)
• support empty here document markers (mksh extension)
• pimp the manpage

tg 0d6e622b14 return EOS on EOS just to be on the safe side 2011-05-04 22:38:27 +00:00
tg 69f98bca9a • fix wtf(1) by keeping the paren in ${foo#\(} properly escaped in COMSUB
• merge tputS and wdstrip_internal
⇒ net save: 604 .text 0 .data 0 .bss (MirBSD/i386)
2011-05-02 22:52:54 +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 d57a033057 • no longer use <stdbool.h> even if it’s available
• ensure that bool/true/false are cpp macros, overriding any pre-defined
• document the requirement that tobool(x) must map any-type 'x' into bool
• document the requirement that a bool must only be true or false, and
  that it (tobool() rather) must have an identity mapping to 'short'
• possibly fix ksh_func for/and fpFUNCTf – maybe spotted by cnuke@

tg 2dbf82a737 no // style comments in my source code! 2011-04-09 15:05:44 +00:00
tg d4e19b6624 • make DEBUG:dumpchar() not static (consider rolling into shf?) 2011-03-17 21:58:40 +00:00
tg 2a3d4db123 lint is your friend 2011-03-13 01:20:25 +00:00
tg 75db4cdb56 • back out the EXPRSUB change
• optimise some code
• split testcase into two, one with expected-fail
2011-03-12 23:04:48 +00:00
tg 17dbd3bd83 • make EXPRSUB not initiate an ASCIIZ string any more but a wdstring
(token stream, lexer output / parser input), EOS terminated, let
  SASPAREN use the same lexing as SBASE (e.g. COMSUB recursively)
• make wdstrip recursive
• fix processing of COMSUB in wdstrip
⇒ pass comsub-1 test
• expose another debugging function
2011-03-12 21:41:15 +00:00
tg f8659785ac • add a tree debugging dumper #ifdef DEBUG
• use shf_putc (macro), shf_putchar (function) ipv tputc
• replace shf_putchar(x,y) calls for side-effect-less x with shf_putc
• plug another bug in the tree code – '\' → "\\" (backslashes must be
  escaped inside double quotes, too)
• adjust testsuite (and, I _had_ wondered…)
2011-03-08 18:49:51 +00:00
tg 1f392ab09b • more fixes (some regression, some new)
• more testcases, stricter testcases
2011-03-06 17:08:14 +00:00
tg 7a6fb85db5 another _two_, gosh! 2011-03-06 02:28:59 +00:00
tg 14d8cecc82 plug _another_ %; versus %N output formatting bug
(apparently, nobody noticed them because everyone outputted to files,
not to strings, and this logic differs for those)
2011-03-06 02:14:09 +00:00
tg e93daee5f4 dump TCASE as "case $foo in (1) blah ;; esac" not "… (1); blah …" 2011-03-06 00:52:02 +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 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 e5e6857c43 (hopefully) fix the substitution thing for good 2010-02-25 20:18:19 +00:00
tg 4eb17f8752 remove some more of this ugliness 2010-01-29 09:34:31 +00:00
tg 0432f97ffe more KNF, mostly whitespace, this time more manual labour applying style(9) 2009-06-10 18:12:51 +00:00
tg 6b2ad96bac some rather mechanical KNF, now that style(9) clarified on the status
of sizeof() as a function-like unary operator; use parenthesēs around
sizeof and return args consistently too
2009-06-08 20:06:50 +00:00
tg b145ca5c9f • sync distrib/special/mksh/Makefile with bin/mksh/Build.sh and
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
2009-05-16 16:59:42 +00:00
tg d2b5538f55 some int->bool, KNF, ... 2009-04-07 19:13:11 +00:00
tg 31d1499219 * back out almost all of the memory allocator related changes, as aalloc
was hard to type and hard to fix, galloc is also hard to fix, and some
  things I learned will probably improve things more but make me use the
  original form as base (especially for space savings)
* let sizeofN die though, remove even more casts
* optimise, polish
* regen Makefiles
* sprinkle a few /* CONSTCOND */ while here
2008-12-13 17:02:18 +00:00
tg 4d3fc2413e switch to a (nmemb,size) API from a (nmemb*size) API
cost: text += (308, 256, 4, -100)

tg c80c28633b change use of “Area *” to “PArea” and “struct Area” to “TArea”
no change in size (mgcc and pcc, small and full)
2008-11-11 23:50:31 +00:00
tg 88d7b7d08b • rewrite code to no longer use statements-as-expressions
• optimise a little
• Build.sh: remove HAVE_EXPSTMT test
• Build.sh, */Makefile: sort tests, regenerate
• mksh.hts: sync clog
2008-10-28 14:32:43 +00:00
tg c11187f993 fix some of the things scan-build[1] found (but not some false positives)
