tg 4cc5fc3e29 avoid C99 constructs even in debugging code 2012-05-04 18:45:03 +00:00
tg b67de6ba17 add experimental code to use sigprocmask+pause+sigprocmask ipv sigsuspend (and harden j_sigchld handler for that) to improve working on BeOS 5.0 and Coherent UNIX, found by RT 2012-04-27 16:16:23 +00:00
tg 5204e7cc4f after discussion with ciruZ, switch mksh from NZAT to NZAAT fully
to get rid of the bias introduced by making the hash never zero

… he also pointed out a memory (heap) usage optimisation… which
may impact code size a bit though as I’d need to pass an additional
argument on hashtable function calls… or, forgo the benefit of not
having to pointer-align the key in the structure, which can be as
much as 3/7 octets per item, heap storage… OTOH the saved space is
4/8 octets per not-allocated item, possibly some code (use of an
multiply-add opcode), but the function call overhead/cost would
possibly be quite a bit… I guess I’ll have to measure…

tg 48da83288d work around segfault bug in GNU sed 2.03, spotted by RT on Debian 0.91 2012-04-16 17:49:40 +00:00
tg ea6b0c60f5 write a bit about pcc, 386BSD, klibc 2012-04-14 19:35:43 +00:00
tg 5eea59ad57 rewrite maketemp() obsoleting tempnam(3) and mkstemp(3) external deps 2012-04-14 16:07:48 +00:00
tg 70e6988d25 factor out rndget() code, for adding users
XXX in the future, the entire scheme must be rethinked when we need more
XXX entropy for the hash tables; possibly a cheap add using NZAT and re-
XXX initialise the LCG only on access and when added (so keep NZAT state
XXX separate from LCG state); also, then we will need a more elaborate
XXX scheme, such as adding from environment, editor keypresses and timing

tg 0e0b379615 sometimes <stdlib.h> doesn’t provide NULL but <stddef.h> does (386BSD) 2012-04-14 14:04:13 +00:00
tg 29e4269f33 if the OS does not provide sig_atomic_t and/or ssize_t, you can now define
MKSH_TYPEDEF_SIG_ATOMIC_T and MKSH_TYPEDEF_SSIZE_T via CPPFLAGS to the
*correct* definitions (it’s absolutely critical they be correct!)
2012-04-14 14:02:40 +00:00

tg 5d4492608a more speling 2012-04-06 15:23:11 +00:00
tg 3d3081115b if LDSTATIC is not empty (i.e. "-static" or " "), always add “our” sources:
• strlcpy
• utf_wcwidth
note strchr/strstr from misc.c are still #ifdef DEBUG only, as they are
not eligible: they’re for const-cleanliness debugging purposes

XXX get rid of multiple occurrences of binary search code, too…

tg 4a89ae1cd0 drop the need for strcasestr: just uppercase a copy and compare with uppercased 2012-04-06 12:59:28 +00:00

tg ff0d8cd3e9 rewrite the EINTR importing code with help of stsc from #nosec on IRC,
and add a semicolon to the end of the BEGIN block (RT says it fixes LynxOS)
2012-04-06 12:22:14 +00:00
tg 6faa68ff8b LynxOS defines PRINT somewhere, undef it 2012-04-06 11:51:43 +00:00
tg 6ca4228e7c disabling jobs just when there is no ctty isn’t needed, at least for BeOS
XXX recheck this with all the others, e.g. NeXTstep
2012-04-01 17:48:24 +00:00
tg 3b2d9322ec change signal probing order: prefer e.g. SEGV over BUS when same Nr. (BeOS) 2012-04-01 17:17:45 +00:00
tg c30bf73a56 BeOS has no tty nor uid/gid other than 0, a̲n̲d̲ a broken /bin/sh 2012-04-01 16:55:16 +00:00
tg 412a96d29a speed up Generating list of signal names (XXX can we wrap this into one compile, anyway?) 2012-04-01 16:40:26 +00:00
tg 607a2af260 found the actual reason… cc -E does syntax check and wrap with whitespace ☹
also we can only do NeXTstep 3.3 with -posix, but not 3rdpty egcs or OS 4.2

tg 820b6e905c make even Errno.pm optional 2012-04-01 04:03:08 +00:00
tg dd5fbe82f3 hide persistent history stuff if not enabled 2012-04-01 03:23:08 +00:00
tg a3fd4f62e6 • move behavioural changes topmost (locale, zsh emulate sh, solaris xpg)
• attempt to handle cpp on nextstep by using -save-temps
• work around another nextstep bug that may or may not hit us, found by RT:
  ‣ http://lists.gnu.org/archive/html/autoconf/2003-11/msg00094.html
• hide "dirname: command not found", scary even if it might help debugging

tg 9646c98356 I give up on writing (1 << 31) in any form.
Now we just use 0x80000000UL and cast that to mksh_uari_t and,
if required, that to mksh_ari_t afterwards.

tg ac18ec3752 one more case of cpp(1) wanting C syntax on NeXTstep 2012-03-31 17:42:58 +00:00
tg 307224f143 Use “proper C code” for determining the compiler type even though we use
only cpp for this: NeXTstep things otherwise:
] conftest.c:42: illegal external declaration, missing ;' after `gcc'
| NeXT Computer, Inc. version cc-437.2.6, gcc version 2.5.8
| NeXT DevKit-based CPP 3.1
| GNU Objective-C version 2.5.8 (80386, BSD syntax) compiled by GNU C version 2.5.8.

tg e67b98e21b use _setjmp/_longjmp on NeXTstep: its Intel port always restores the signal mask on siglongjmp, which we never have 2012-03-31 17:30:00 +00:00
tg 86c4ea4619 add (#ifdef DEBUG) an assertion that xcp <= xep before doing an Emacs mode
command; DONG-DONG YANG reports they hit this condition
