tg 954352cae3 some more code “folding”
should decrease size
2008-04-01 22:20:20 +00:00
tg 37af1f3087 more
• int → bool
• shprintf("foo") → shf_puts("foo", shl_stdout)
• shprintf("%s", foo) → shf_puts(foo, shl_stdout)
• shf_puts("x", foo) → shf_putc('x', foo)

tg 3ad04ea095 reorganise c_typeset code, fixing that regression test
also some int→bool while here

tg 5728495366 revert wrong fix 2008-03-28 18:46:59 +00:00
tg 2f0c894290 • fix one more of the enum arithmetics complaints
• split Xinit into XinitN and Xinit macro, the former
  not initialising the “xp” argument of the latter,
  and use this to get rid of two variables that are
  only assigned but never referenced (gcc doesn’t see
  this, but MIPSpro and IIRC SUNWcc do)
• re-indent while here
• bump patchlevel
2008-03-28 13:46:53 +00:00
tg 66f433ace0 fix most of the fixable bitchings of MIPSpro compiler (complainer?) 2008-03-28 13:28:33 +00:00

tg d16fc19335 live code from FOSDEM: add print \xDB and \u20AC, including regression test
agreed bsiegert@
good idea and manpage diff ok'd by some netbsd person sitting next to me
2008-02-24 15:48:43 +00:00
tg 6976ed8bc3 get rid of u_char, u_int, u_long 2007-10-25 15:23:10 +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 1e3783f030 employ string pooling techniques to save off a few more bytes
(probably more than the new “rename” builtin ever required…)
2007-08-19 23:12:23 +00:00
tg ca46f3dc98 new builtin “rename” (this name sounds better than “mksh_mv_rescue” ☻)
to just call rename(2) directly, e.g. if /bin/mv needs /lib/ld-uClibc.so.0

some assorted code cleanup

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 e392983af7 Possible fix for Coverity CID#7:

tg 3daaf229ca Fix for Coverity CID #6 (null pointer dereference in error path) 2007-05-13 18:15:25 +00:00
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 377dbe464a some gcc 4.1.2pre warning shutup 2007-03-10 18:16:28 +00:00
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 5891915f1b * Scan for __attribute__((...)) in general (the earliest was 2.5,
where we had 'noreturn' etc. but no '__noreturn__')
* Scan for __attribute__((bounded)) and __attribute__((used))
  if we have __attribute__((noreturn))
* To be able to scan if certain attributes give warnings,
  scan for -Werror with a simple programme which hopefully triggers none
* Convert __attribute__((unused)) to __unused, noreturn -> __dead
* Unify other attributes
* Clean up typography a little more

tg 2f15a11c55 Clean up the signal mess, saves 172 Bytes:
* 'sigseen' in Build.sh goes away
* Signal name existence is checked in this order:
  have our own¹ -> sys_signame[] -> _sys_signame[] -> build our own²
* Signal description existence is checked in this order:
  sys_siglist[] -> _sys_siglist[] -> strsignal() -> NULL³
¹ Predefined list of items, for operating systems where we
  cannot build² them, i.e. Plan 9 and Minix 3 (e.g. no $CPP -dD)
² The usual cpp(1) stuff
³ Changed later, see below
* Make $CPP test dependent on $NEED_MKSH_SIGNAME (others can
  be added here, this is not absolute)
* Make signal name list generation² dependent on $NEED_MKSH_SIGNAME
* Fix check if the generation worked
* Guarantee that sigtraps[*].name and sigtraps[*].mess are valid
  C strings; this makes the code shorter *and* removes a few pos-
  sible nil pointer dereferences
* Embed autoconf'd usages of sys_sig* / strsignal / mksh_sigpairs
  into inittraps()
* Check for each signal 0<=i<=NSIG that
  name is not NULL or "" -> replace with ("%d", i)
  mess is not NULL or "" -> replace with ("Signal %d", i)
  name does not start (case-insensitive) with "SIG" -> name += 3
* In gettrap(), fix check if signal name starts, case-sensitive
  or case-insensitive, depending on need, with "SIG" (bug from millert@)

Other changes:
* Build.sh: ac_test[n]() are documented
* Build.sh: ac_test[n]() can have negative prereqs as well now
* Build.sh: use <<-'EOF' consistently
* bump patchlevel to today

tg 6775d79b2a Revision [7]1.16 / ([8]download) - [9]annotate - [10][select for
diffs] , Mon Nov 20 21:53:39 2006 UTC (2 weeks, 1 day ago) by miod
Compute user-given ulimit value times ulimit unit as an rlim_t value, not a
long value; catches some 32 bit overflows on 32 bit platforms.

tg 8a4b64fde3 fix 'typeset -p' to act according to TFM and ksh93 2006-11-19 17:13:36 +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 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

tg 2342fa1242 don't use setreuid(2) etc. stuff, like OpenBSD

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
