tg ccb41ecb4d shut up some gcc warn_unused_result thingies from Fedora 2007-09-09 19:12:10 +00:00
tg 6b9c277fbc shut up tcc 2007-08-20 14:12:29 +00:00
tg 809c1446b2 some steps towards building with tcc 2007-07-31 10:42:15 +00:00
tg b09b3621e2 • we had an unused variable leftover
• make warning-free for both gcc and xlC
2007-07-22 14:01:50 +00:00
tg 979406bba7 • support IBM xlC on AIX
• fix all bugs it could find ☺

tg 2e42fa62b6 Borland C++ found these 2007-07-01 21:10:29 +00:00
tg 9f61aea3de fix mmap args and retval (cosmetic) 2007-07-01 17:13:52 +00:00
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
2007-06-06 23:28:17 +00:00
tg 91431e4cf6 with this, we don't need the special list of pre-known signal names
any more either, and can make use of code sharing between detection
of sys_siglist and sys_signame (and the underscored variants); nuke
the now-useless signames.c file too (merge struct into histrap.c)
2007-06-05 21:47:49 +00:00
tg 1e93f97b8c compile warning-free on SUNpro (regression test suite pass) for MirBSD 2007-06-04 21:33:28 +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 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 67a28c4c3f typo, prevents compilation under Interix (has _sys_signame[] array) 2007-02-27 15:03:28 +00:00
tg bca0f4d603 * Build.sh, histrap.c: prevent testing of strsignal() if we have sys_siglist[]
* mksh.1: .Nm is never used with "" as argument, fixes GNU groff 1.15
2007-01-17 23:47:15 +00:00

tg 0b7376a1ad * histrap.c: picky /a1/sw/pkgs/gcc-3.4.3/bin/../lib/gcc/sparc-sun-solaris2.8/3.4.3/
* main.c: thinko
2007-01-12 02:06:34 +00:00
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 0e4bbd4bf6 * inittraps: convert signal _names_ to uppercase, we're matching
case-sensitively in the 'trap' builtin, and Mac OSX has them
  in lowercase at sys_signame[]…
* gettraps: optimise
2007-01-12 00:37:09 +00:00
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 5b525d79fb format string warnings, courtesy of Interix 3.5 2006-11-12 12:49:25 +00:00
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

tg ca2b1d88ca kill two others, saves 55t 8d 2i 2006-11-10 06:40:05 +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

tg 208c45da25 more cleanup; incidentally, replacing libc function with syscall maybe speedup
9t 4d 1i
2006-11-10 04:22:13 +00:00
tg a1ff719ba4 thanks to the nice property of my reimplementation of getn to also
return a value in case of an error (0 or the partial result, which
is the full result in case of trailing junk even), using it to rid
atoi() is possible, saving 9t 4d 1i
2006-11-10 04:03:59 +00:00
tg ecc08e9681 use chown not fchown, and move the ownership check to earlier
saves 45 text, 4 data and security peoples' nerves
2006-11-10 03:50:05 +00:00
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 65f0044ceb make it possible for the user to specify mksh_siglist and mksh_signame
in CPPFLAGS, thus overriding the system default
(think standard OS with different libc)
2006-08-01 13:19:42 +00:00
tg e65d9edc11 * use strsignal(3) not strerror(3), oops
* on GNU, that needs -D_GNU_SOURCE

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
