tg 0a3fe06229 another MidnightBSD /bin/sh kludge: classic BSD echo 2013-02-18 22:47:32 +00:00
tg 744f77c668 fix running the ERR and EXIT traps in case of set -e and/or eval (includes Debian #696823) 2013-01-01 20:45:04 +00:00
tg b2396677e7 harmonise sys_{sig,err}list ⓐ checks, ⓑ uses, ⓒ _decl values when not needed, ⓓ prototypes; ⓔ “const” is a keyword and thus space-separated from the preceding ‘*’ pointer indicator 2012-12-28 02:28:39 +00:00
tg 12c662b6e2 thanks to ISC (Interactive) Unix, we now know a few samples of errnos
that get used, plus one for the realpath-1 regression test; also make
sys_siglist_decl detection nicer and poison strerror() with non-const
return value ifdef DEBUG, make it always const

tg b868c517b7 remove *all* nonnull assertions and other workarounds for clang scan-build
this beast evolved in the last 2½ years, and we’ve had trouble with
some of them earlier

tg c7419d9e6a defer setting exstat for eval to 0 (the one used in case shell() is empty)
until after the stuff run in shell() has had a chance to toy with $?

bug forwarded by one of our packagers, found by one of their users
2012-10-21 21:55:05 +00:00
tg 31f24a4040 add some bounds, for a subsequent commit:
• all writers of exstat ensure the value is in [0; 0xFF]
• all readers of exstat AND it with 0xFF (not strictly needed thus)
• trap_exstat is “safe”, i.e. always either -1 or [0; 0xFF]

tg 3125146b43 Fix typeset issues (LP: #993847)
This was actually more evil:
• use a recursive function to display blocks in reverse order,
  so that local variable values overwrite global ones
• add array support to typeset -p (from typeset -p -)
• display 'set -A varname' line before setting values, for -p
• if -p got arguments, only display those (from the innermost scope)

Also, the usual amount of code cleanup…

tg 7beac6668d provide for Coherent not having gettimeofday(2), imake style (bad, but this is not for others to use without a second thought anyway) 2012-05-04 21:47:04 +00:00
tg 2d31aca859 more int→bool while trying to let ^D output CR+LF (which shan’t be, oh my…) 2012-05-04 21:15:34 +00:00
tg 5780bc5eb7 new MKSH_NO_CMDLINE_EDITING to disable command line editing in its entirety
mainly for the Plan 9 port though it may also help the WinAPI variant,
other porting efforts, as well as a new project I cannot say yet
2012-05-04 20:49:08 +00:00
tg 7c4bf78446 move bi_getn from misc.c to funcs.c and make it static
even antique gcc versions will usually inline it now

tg cf75e7b6ce couple of minor/cosmetic fixes from RT’s compile farm:
• promote SCO OpenServer and UnixWare to !oswarn
• omit trying -O2/-O on OpenServer 5 and USL C
• cast mksh_ari_t to int, mksh_uari_t to unsigned int for printf
• skip ulimit-1 on syllable (which is still too broken)
• write ((mksh_ari_t)-2147483648) ipv UB ((mksh_ari_t)1 << 31)
  and add a comment that that is actually meant
• rewrite functions returning !void ending in NOTREACHED
  so they’ve got a jump target returning an error at the
  end, to aid older compilers and just to be safe
• cast struct stat.st_size to off_t or size_t explicitly when needed
• shorten struct env by two bytes and an alignment, at least

also, optimise control flow and fix more paren matching cases

tg e83e43aaa5 block things like SIGWINCH¹ during builtin sleep, they get rescheduled
on unblock just fine and hurt since they interrupt select(2)

① and² SIGPIPE, SIGINFO, SIGUSR{1,2} in addition to already blocked SIGCHLD
② exact list open for suggestions – I’ve got no idea what I’m doing…

tg 73688b3b3c oh well, shove it; inline some things, the most legible ones
mostly for benefit of not-the-latest-llvm-or-gcc compilers

tg 1ac636670f • improve comments
• do shave off 20 bytes from c_test() and get rid of the ugly stack
  variable and double “using” despite not parsing
2011-12-02 22:55:49 +00:00
tg 2fb9df56e4 rewrite funcs.c:c_test(), i.e. test(1) and [(1), to follow POSIX and XSI
in the cases where they are defined unambiguously; bug reported by
Jilles Tjoelker in <20111129232526.GC14357@stack.nl> due to a report
by Stefano Lattarini on bug-autoconf

in the ambiguous case, I stick to traditional pdksh behaviour, which means
	test ! a = b	vs.	test a = b
and
	test ! a -o b	vs.	test a -o b
behave different from each other (in the second case, the NOT operator
binds strong; POSIX demands a reduction to 3 arguments and negating
that result in the first case), so we're at two known not-ok in the
FreeBSD® testsuite. (81 and 82 in regress.sh,v 1.3)

seen in dietlibc’s source code

tg f2405b7dde • bump patchlevel to today’s
• while here, reformat 'struct tbl' comment-wise and placement-wise
  and drop the Tflag typedef
• while here, write regression test for the "global" built-in, which
  does what typeset is supposed to do except that it doubles as "local"
