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 0b4f34e0a8 • syn.c: replace expanded use of str_save() with the actual macro
• others: fix 6 (!) cases of non-constant or side-effect arguments
  to the str_save() or str_nsave() macros, and other abuse of them
• also fix some cosmetics and other un-nice code while here
2008-07-12 16:56:40 +00:00
tg f17b8b1c8b • alloc() can’t fail, afree() can take NULL
‣ macro afreechk() is superfluous
• get rid of macro afreechv() by re-doing the “don’t leak that much” code
• some KNF (mostly, whitespace and 80c) while here

tg 4230cf91de thinko: multibyte characters are not always 1 column wide 2008-05-02 18:55:37 +00:00
tg 9b62cf15bf • more unsigned → unsigned int
• 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 ☺

tg 7ddf56dbbc • new ksh_mbswidth
• fix: when printing menus (tab expansion, for instance), honour width of
  the multibyte characters printed
• some int→bool while here

tg 1a5ea7052c sync w/ oksh 2008-02-24 15:20:52 +00:00
tg 7c0db962eb oeps… unbreak 32-bit array indicēs (or rather, wrap of negative indicēs
into the positive high range) on 64-bit platforms: just always wrap and
ignore the result, remove the nonsensical out-of-range check
2007-10-25 16:10:16 +00:00
tg 6976ed8bc3 get rid of u_char, u_int, u_long 2007-10-25 15:23:10 +00:00
tg 13676f4914 even better: don't require 64-bit types at all
also, improve wording of Build.sh (passive terms)
2007-10-25 14:26:53 +00:00
tg bbbe959bf2 only check for 64-bit integer types if needed (arc4random support) 2007-10-25 14:18:56 +00:00
tg 97ba2fabc7 first step towards mksh R32 ☺
allow array indices in the uint32_t range (0‥4294967295) and map negatives
into that range; adjust manual page and regression tests; to be used RSN ☻

tg c1c939e340 • fix memory leaks found by coverity
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

tg 3dcf22a319 ok, icc _did_ track down a few ones, and I fixed errno abuse a little too
however, bad S/N ratio

side effect bonus: smaller code size now

tg 0989f7da67 Fix for Coverity CID#2: false bug, but still a problem.
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))

tg 83c2ee87f4 • remove strcasestr.c, use home-grown implementation¹, call it stricmp,
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

tg c480656076 shrink .data a little 2007-01-15 02:48:28 +00:00
tg c2e79abc08 make mksh compatible to the AT&T ksh spec which says, according to
twkm (from #ksh on freenode), that $RANDOM is always an unsigned
15-bit decimal integer.

(RANDOM << 15 | RANDOM) thusly yields 30 bit, which is still more
than 36^5, so we can use it on the baselife CD to speed things up
2006-11-19 16:43:43 +00:00
tg 151d913115 remove all but these __CRAZY=Yes build warnings:
main.c: In function 'main':
 main.c:208: warning: cast discards qualifiers from pointer target type
 main.c:329: warning: cast discards qualifiers from pointer target type

no warnings at autoconf time left either; will take care of these two later
(might revisit changes from this commit), maybe change declararion for the
builtins to have their argv[] be const strings, and go through strict type
and qualifier checking again. this'll further improve stability.

XXX these changes might have introduced (more?) memory leaks,
XXX someone who knows about these tools should verify with
XXX automatic memory usage analysers (valgrind?)

still passes testsuite

tg 56ffbf7e70 hand-sorted ctypes/chtypes upgrade; use table-driven where they make
sense and preprocessored otherwise; unify the logic
saves 144t 1i and lots of cpp(1) time, as well as improves readability
2006-11-10 07:52:04 +00:00
tg feb7dddd44 * use only macros for ctype stuff any more
XXX one of these uses a gcc extension, ok for now tho
* don't include <ctype.h> any more at all
* don't try nl_langinfo in small mode, just check locale

saves 171 .text, 4 .data, 256 .bss, 1 import
2006-11-10 07:18:58 +00:00
tg 35b30679c7 since so many internal things hardcode 'C' locale anyway,
use own is{digit,lower,upper} macros that go via byte ranges

doesn't affect utf-8 hack because these only operate on single bytes anyway
saves 224t
2006-11-10 06:53:27 +00:00
tg b323a22b59 use tolower_() and toupper_() macros (if not available, our quick 'C' ones)
76t 8d 2i
2006-11-10 06:45:28 +00:00
tg 2342fa1242 don't use setreuid(2) etc. stuff, like OpenBSD
only affects suid shell scripts, which are *ugh* anyway,
and I really have no idea what the old code did, when, why, etc.
262t 16d 2i
2006-11-10 06:16:25 +00:00
tg 493ad928e3 if MKSH_SMALL, disable persistent history code as well (like on Solaris,
where it can't work anyway), and fix that code to shrink
saves 2071t 20d 5i
2006-11-10 05:23:14 +00:00
tg 208c45da25 more cleanup; incidentally, replacing libc function with syscall maybe speedup

tg 273ca89019 * check.t: add new regression test "typeset-padding-1" according to TFM
* edit.c: remove debug stuff again; next time better use shl.c functions ;)
* sh.h: add format attributes to a few shf functions
* histrap.c, var.c: fix format string mistakes
* main.c, sh.h: error_prefix and warningf take bool not int
* misc.c: make chvt() stuff use shf_* functions
* misc.c: rewrite the TIOCSTTY stuff to be better integrated in mksh,
  since it originally was an external patch
* misc.c: chvt() no longer fails if e.g. chown fails due to e.g. R/O / fs
* var.c: fix typeset padding for right-justified zero-filled

tg 14a65d55e6 pull in last OpenBSD diff - I must admit I neither fully understand
the diff nor the commit message, but they're probably knowing what
they're doing

on an unrelated side note, mksh-beta.cpio.gz didn't get tested by
many people... so mksh R27 will be released without much more...

Set the index of item[0], since it might not have been set before
(A=0; A[1]=1) and do not use a static buffer in str_val, since the
results might be used in a loop. Report from jared r r spiegel; help
from Matthias Kilian; ok beck@

tg 7672b9b346 apply some fixes from OpenBSD and don't apply some others
but sync RCS IDs for easier future adaption:
* Simplify savefd() by removing the "noclose" flag and make noclose
  behavior the default. Almost all uses of savefd() are followed
  by an implicit or explicit close.
* fix typos
* might as well make ksh_getopt() match real getopt(), ie. get rid of that
  stupid EOF concept that was never true. adobriyan@gmail
* use SEEK_* for lseek()
* fix lint comments, no functional changes
* remove excessive optimization; from adobriyan@gmail
* only santa checks things twice; from adobriyan@gmail
* Interpret zero-filled numbers as decimal; PR 4213; from Alexey Dobriyan
