tg cc783807d3 this began as a one-word change to the spec (manpage): that
${foo:1:2} operates on characters ipv bytes – which means:
‣ set +U: octets
‣ set -U: MirOS OPTU-8 characters

for consistency I also adapted ${#stringname} to deliver the
length in characters ipv bytes; more may follow; for example
I’d like a way to expose the string width.

you can already get the MirOS OPTU-16 of a character in the
WTF-8 (「set -U」) mode with something like
│ typeset -Uui16 -Z7 x=1#${stringname:position:1}
which will correctly use the PUA EF80‥EFFF mapping for octets.

due to this being an incompatible change, bump to R38

also change the unicode-hexdump sample regression test and
add two news for ${x:1:2} and ${#x} checks in A/W mode ☺

tg db6ed8be7c ... and it did in fact require DEC ucode cc to spot this!
gcc, SUNWcc, pcc, llvm-gcc, clang, etc. all didn't say a thing!

and OSF/1 X2.0-8 (testsuite norun: perl missing) has only the usual
bitchings about "volatile sig_atomic_t" because the latter part is
already volatile, but otherwise warning-free compile, works fine

tg b20f49adae patch from oksh (except manpage, I'll merge that later):
pass "xerrok" status across the execution call stack to more closely
match what both POSIX and [18]ksh.1 already describe in regards to set
-e/errexit's behavior in determining when to exit from nonzero return
values.

specifically, the truth values tested as operands to &&' and ||', as
well as the resulting compound expression itself, along with the truth
value resulting from a negated command (i.e. a pipeline prefixed !'),
should not make the shell exit when -e is in effect.

tg 4897682502 Alias expansion has a recursion check which tries to break the cycle if
encountered. However, when reading end of input, the source type is set
to SEOF while popping, whereas the recursion check code only checks for
an SALIAS type.

Fix: add a new SF_HASALIAS flag; change u.tblp from being valid if type
is SALIAS to being valid if SF_HASALIAS is set; set SF_HASALIAS for the
created SALIAS sources; set SF_HASALIAS and u.tblp when creating SALIAS
whose next is SEOF on the SEOF source as well.

• fix multi-line prompts if last line is “too large” by using emacs mode
  algorithm of just internally appending a newline, while here ☺ this even
  saves us having to re-add the prompt_skip variable…

tg 604ec0ff6c remove dead code and ifdefs, speed up configuring 2008-05-04 01:51:31 +00:00
tg 4230cf91de thinko: multibyte characters are not always 1 column wide 2008-05-02 18:55:37 +00:00
tg 1ed64c3e26 bump 2008-04-22 19:00:41 +00:00
tg a3dab099d9 sh.h can provide its rcsid itself, no need for that ugly hack 2008-04-22 18:57:26 +00:00
tg 5fb55148a1 merge the fix for that segfault 2008-04-20 01:41:57 +00:00
tg 309c674ed7 mostly revert 100480A853206FB56FA and parse utf-8 lead bytes ourselves 2008-04-20 00:24:26 +00:00
tg e20694eceb utf-8 function overhaul (size optimisation)
XXX maybe we can get more out of this?
2008-04-20 00:03:50 +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 ☺
2008-04-19 22:15:06 +00:00
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
2008-04-19 17:21:55 +00:00
tg 6c6be2a87e _careful_ (feature) sync with oksh:
(3 weeks, 5 days ago) by millert
Make ulimit able to get and set multiple limits in a single invocation
like bash and zsh do.  Requested by espie@, OK deraadt@
2008-04-16 21:56:03 +00:00
tg fc607a6c1b SECURITY fix: when spawning mksh on a new terminal (tty, not /dev/null),
flush all of its I/O first – someone could have written on it beforehand
2008-04-11 19:55:24 +00:00
tg afaa3ffa59 move some portability stuff required only for setmode.c into that
(XXX we somehow do need a sorta libbsd…)
2008-04-06 23:27:19 +00:00
tg acc2e9a67a • Ultrix doesn’t define MAP_FAILED either
• on Ultrix, mmap() returns a caddr_t instead of a void*, so cast
2008-04-02 16:55:06 +00:00
tg 954352cae3 some more code “folding”
should decrease size
2008-04-01 22:20:20 +00:00
tg e8d61a1d99 • unify ksh_dup2() usage, use bool where appropriate
• apply diff from mirbsdksh-1.11:
  #ifdef DUP2_BROKEN
  /* Ultrix systems like to preserve the close-on-exec flag */
  ‣ XXX we do #ifdef __ultrix here (imake-style) instead of mirtoconfing it
    (but does anyone know of any other OS with the same problem? plus we’d
    see it as we now know the symptoms)
• remove ultrix Build.hs warn=' but might work…' in the hope it DOES
2008-04-01 20:40:22 +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 def9c172df • Add support for Ultrix 4.5 and ucode cc (?)
‣ I/O redirection seems broken:
    $ (date; date >/dev/null; date) | wc -l
    1 (expected: 2)
  ‣ other than that: working fine
  ‣ -YBSD (default) and -YSYSTEM_FIVE don’t work, just -YPOSIX, somehow
• Fix $(…) to `…` for OSF/1 V2.0 /bin/sh
  ‣ this compiler is FUBAR though:
	$ cat >t.c
	main() { return (foo()); }
	$ cc t.c
	ld:
	Unresolved :
	foo
	$ echo $?
	0
	$ ls -l a.out
	-rwxr-xr-x   1 mirbsd   users      10835 Jul 21 17:12 a.out
  ‣ it seems to have ucode, but man is not installed
• new mirtoconf check: mkstemp(3)
• if !HAVE_MKSTEMP (Ultrix), use tempnam(3)
• only use printf(1) if it exists (it doesn’t on Ultrix)
• a few more signals
• add S_ISLNK if the OS doesn’t define it
• add strcasecmp(3) proto for Ultrix (it _is_ in <portability.h>, but
  only for -YBSD I think)
• fgrep(1) on Ultrix doesn’t do “-e ① -e ②”

10x DEChengst:#UnixNL for giving access
2008-03-25 21:34:45 +00:00
tg 83b8798da3 support dæmonisation in mksh, for example
|	csh -cf '/command/svscanboot &'
and
|	/usr/mpkg/bin/pgrphack /usr/mpkg/bin/svscanboot &
can now be replaced with
|	/bin/mksh -T- /usr/mpkg/bin/svscanboot
2008-03-23 22:09:59 +00:00
tg 26ba2854a2 support BSD/OS 3.1 with gcc2, 10x replaced@tnf
except MAP_FAILED not being defined, no issues
2008-03-23 20:55:18 +00:00
tg 845f6f0d64 • check for flock decl too (weird on OSF/1: if !POSIX and BSD)
• un-experimental Tru64
2008-03-05 18:49:15 +00:00
tg 0e6df4736a • now this builds fine on DEChengst’s Tru64 box:
| OSF1 rubbereendje.dechengst.nl V5.1 2650 alpha
  with the vendor compiler:
  | Compaq C V6.5-011 on HP Tru64 UNIX V5.1B (Rev. 2650)
  | Compiler Driver V6.5-003 (sys) cc Driver
• the platform’s sig_t is incompatible too (simplify check)
• no compile warnings at all
• results in:
  $ size mksh
  | text    data    bss     dec     hex
  | 327680  16384   17808   361872  58590
  $ file mksh
  | mksh:   COFF format alpha dynamically linked, demand paged executable or object module not stripped - version 3.13-14
  $ ldd mksh
  |
  |         Main  =>   mksh
  |         libc.so  =>   /usr/shlib/libc.so
  $ ls -l mksh
  | -rwxr-xr-x   1 mirbsd   users     395200 Mar  5 19:18 mksh
• minor testsuite issues:
  FAIL ./check.t:regression-13
        unexpected stderr - got too much output
        wanted nothing
        got:
                Successful
                cat: output error
  ⇒ probably harmless
• works like a charm!
2008-03-05 18:21:45 +00:00
tg 3d9bd0e1f0 OSF/1 doesn’t seem to declare revoke(2) anywhere 2008-03-05 17:06:50 +00:00
tg 4912b5cf67 quite a big change, but now the variables expanded are not
scanned for slashes, plus the ADELIM code gets more use and
a bugfix ☺
2008-03-01 21:10:26 +00:00
tg 36c4552e1f we don't need to be special if called as -sh any longer now 2008-03-01 02:21:38 +00:00
tg 8aa54e42a9 fix 2008-02-27 12:49:54 +00:00
tg 85b0cb20eb almost hack ${foo//bar/baz} support for real, now
still one corner case left ☹
→ 11:09⎜«Han:#UnixNL» Ik _haat_ bash
⇒ kann ich mich nur anschließen…
2008-02-27 11:24:12 +00:00
tg 01b54f1fd5 I _think_ this implements ${foo/bar/baz} logic (bar is a glob pattern)
todo tomorrow:
• test case (compare with e.g. GNU bash)
• manpage
• version bump

sqchar is a bit ugly, but \/ must be preserved, as we don’t get wdencoded
strings later on in the process (eval.c CSUBST) and I didn’t want to have
an implementation like ${foo: 2: 3} this time
2008-02-27 01:00:10 +00:00
tg 5ea53a15c7 implement “here strings” 2008-02-26 20:43:11 +00:00
tg 9b1504a221 move some constants private to the lexer into its .c file 2008-02-26 20:35:25 +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 98f0a3c101 oops 2007-10-25 15:34:57 +00:00
tg 6976ed8bc3 get rid of u_char, u_int, u_long 2007-10-25 15:23:10 +00:00
tg 3b5bbaefcb optimise (struct padding, function→macro, etc.) 2007-10-25 15:19:16 +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 2ca968e25f • fix for the pipeline-as-coprocess problem
• bump to mksh R32
2007-10-25 13:51:19 +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 ☻
2007-10-18 20:32:33 +00:00
tg e2c2a1c1a0 clean up the CHARMASK mess 2007-10-14 13:43:41 +00:00
tg 52b9911ff6 revert the return type of x_e_getc() back from u_char to int
this change broke abortion on failure to read input, was not
needed for gcc warnings and is the fault of Intel’s compiler

this should fix the other busy-loop problem occuring only on
GNU/Linux so far – 10x spaetzle@freewrt.o for pointing me to
the problem; reproduced on my work craptop
2007-10-09 14:50:50 +00:00
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
2007-09-09 18:06:42 +00:00
tg b82204aa3d proto 2007-08-20 14:06:10 +00:00
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
2007-08-19 22:06:27 +00:00
tg e99f988aae feature freeze for mksh R31, to be released as part of MirOS #10 2007-08-18 00:22:09 +00:00
tg f684b0ceb1 Implement the “source” command, as requested by some and agreed bsiegert@
In contrast to AT&T ksh93, its semantics are like GNU bash in that it ap-
pends the current working directory to the search path; it is implemented
as a shell alias instead of enhancing funcs.c:shbuiltins[] like in ksh93.
2007-08-13 19:39:21 +00:00
tg f3bb1472df Debian warning cleanup 2007-08-12 13:52:03 +00:00

prompted by lina output, 10x tarzeau
not a bug
2007-08-06 12:02:39 +00:00
tg 496b8f4dc3 • new way of checking for mknod & friends, due to tcc vs glibc weirdness
• bump vsn for the code restructuring
2007-07-31 11:11:25 +00:00
tg 3718a00106 • test on HURD (gnubber)
• fix unreachable code (break stmt) cought by suncc on yofuh's E420
• bump vsn to today
2007-07-26 13:23:52 +00:00
tg b20e5a90ce initial support for PW32, not quite working yet (same issues as Minix 3 and Plan 9, I think) 2007-07-24 21:47:14 +00:00
tg e37577de42 fix another errexit bug: unwind() is __dead, so the pseudo-signal was never
delivered to the process
• regression test by Clint Pachl, verified against Debian ksh93 by me
• place to fix it in the code discovered by Otto Moerbeek
2007-07-24 11:22:04 +00:00
tg f2a52c65fa … and fix that bug.

2007-07-23 14:28:52 +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 a1433b7122 • Build.sh: always prepend well-known signal names, so that some signals
will not come up weirdly (e.g. on AIX: SIGSAK (SIGMAX?), SIGIO (SIGAIO?),
  SIGURG (SIGIOINT?)), and add a few more while here
• check.t, sh.h: bump
2007-07-22 13:46:15 +00:00
tg cf5fc9eac2 some null/NUL 2007-07-22 13:38:26 +00:00
tg 979406bba7 • support IBM xlC on AIX
• fix all bugs it could find ☺
2007-07-22 13:34:52 +00:00
tg 56a8da33cf • make the "if called as sh, set FPOSIX" not !SMALL-only
• bump to R30-gamma, feature freeze
2007-07-17 13:56:51 +00:00
tg 78d58de7a0 fix the rest of it 2007-07-06 02:22:57 +00:00
tg 26a6e5acc9 make this pass varexpand-substr-1 and ‘c’ of varexpand-substr-2
by actually using the lexer and parser for that
2007-07-06 01:53:36 +00:00
tg f948c13a78 • fix display problem
• add <libutil.h> if it exists – revoke(2) on UWIN
• add <stdlib.h> for NULL in test of mmap(2)
• regen CPPFLAGS for MirBSD native builds
2007-07-01 21:47:08 +00:00
tg 7004525fcc • add support for the Borland C++ Builder (on UWIN)
• add support for the Digital Mars compiler (on UWIN)
• clean up
• describe new build targets and that UWIN sucks
• bump vsn
2007-07-01 21:27:03 +00:00
tg 572119b454 some <getopt.h> from vendors define a “struct option”, so use a
different name for ours
2007-07-01 16:49:18 +00:00
tg ca17798533 this is bash compatibility week, and by suggestion of actual users,
namely Dr. Robert “Pfeffer” Arnold (in this case, in FreeWRT), make
a half-completed attempt at implementing ${foo:2:3} substring evals
(of course, negatives can't work right now and that the numbers are
in face expressions is something I only read later too – this is to
be revisited later, but it's already late)

don't depend on this behaviour yet though

if someone wants to add more regression tests, feel free to…
2007-06-27 23:12:59 +00:00
tg 3a94b076a0 implement bash-style array initialisation, as requested by many
still experimental
2007-06-22 23:34:42 +00:00
tg d42f966d22 rewrite some code; bug found by HP's C compiler 2007-06-21 16:04:46 +00:00
tg e596de4759 make sure that “integer” and “local” are defined even in FPOSIX mode, which
is a compromise anyway; these lunox people will have to live with that, too
many existing korn shell alike scripts depend on it even if not on the full
korn shell syntax availability (note: this doesn't mean using these in some
script with #!/bin/sh is ok)
2007-06-17 00:50:09 +00:00
tg 17b7a28ac8 • check.t: add some FPOSIX regression tests (1 still fails)
• all: remove vi editing mode #if defined(MKSH_SMALL) || defined(MKSH_NOVI)

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 63c31c43e3 fix for the SUNpro 8 on yofuh's E420:

2007-06-05 19:48:47 +00:00
tg 10b48d1f92 on Linux 2.0, <sys/sysmacros.h> defines makedev(), but on Solaris, both it
and <sys/mkdev.h> do it, where the latter seems to contain the newer ones,
it undefines them before redefining too, so move its inclusion up a little

tg 1e93f97b8c compile warning-free on SUNpro (regression test suite pass) for MirBSD 2007-06-04 21:33:28 +00:00
tg 6e1bfd6e4b When compiling native MirOS BSD binaries with SUNpro 12 (don't look like a
car only slower, yes this is possible, and the resulting binary passes the
testsuite just fine), the definition of __RCSID() in <sys/cdefs.h> expands
to something with __attribute__((used)), which triggers a warning, because
__attribute__ in general is supported but the used attribute isn't. Thusly
always use our own strings and get rid of the MULTI_RCSID test (introduced
because __RCSID() on Darwin is inferiour).

Maybe we should fix <sys/cdefs.h> too? #ifdef __SUNPRO_C helps here.
2007-06-04 21:27:53 +00:00
tg 2beb60ebf3 for R30, don't check for confstr() declaration any more
it was #if solaris'd in R28, and the system I have access

tg fcd6e4f07a bump version 2007-05-13 19:18:26 +00:00
tg a84655e3e0 fix Coverity CID #8, #9
it's wrong to use strchr(s, 0) to look for the NUL byte, because in some
environments it apparently might return NULL

use new macro strnul = s+strlen(s) instead (not side-effect safe tho)
2007-05-13 19:14:05 +00:00
tg e392983af7 Possible fix for Coverity CID#7:
convert options() prototype to unsigned (size_t, in fact), and make an

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))

XXX u_int32_t is not ISO C99, but seems to work well enough
  XXX if it fails anywhere, we'll see in the build logs
  XXX apple doesn't have the standard uint32_t and API doesn't specify it
• sys_siglist_defn: rename to sys_siglist_decl as we're really checking
  for the declaration in the headers; change wording to “check if … does
  not need to be declared” since we don't need to declare if we don't use

do not start with a "#!shell" sequence” part of mksh(1) true again; this
  was probably lost in mksh R21 or so when I decided/saw that our kernel
  always parses shebang lines (code written myself, not taken from pdksh

* '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@)

* Build.sh: ac_test[n]() are documented
* Build.sh: ac_test[n]() can have negative prereqs as well now

tg 11282be59d compat.h has a section 'extra headers', move inttypes.h there 2006-08-16 00:00:24 +00:00
tg 98c4dc04a1 interix doesn't have <inttypes.h>, openbsd no <stdint.h>, the old chaos.
so add <inttypes.h> only for the one platform which needs it today, APE.

tg 1e313c282c minor cleanups from the porting work 2006-08-15 23:43:30 +00:00
tg 1100be9300 re-implement "set -o posix" which doesn't do much ;)
but turns off 'braceexpand' when turned on as side effect,
just like oksh/pdksh.
document "set -o sh" too.
2006-08-09 20:44:16 +00:00
tg 790c312e9f fix the prompt redrawal routines for multi-line prompts, prompts
with embedded newline (\n), and multi-line prompts with embedded
newlines. single-line prompts should be not affected; prompts with
embedded carriage return (\r) should be fixed by this as well.
also fix prompt_redraw comment (can't remove the variable though,
since it's required if the shell inserts a newline after the prompt
herself).
tested on cygwin and interix

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
2006-05-10 18:54:13 +00:00
tg 5726a50ab9 * shuffle around _*_SOURCE definitions (sh.h -> Build.sh), per OS
* Tonnerre Lombard reports that Solaris 10 needs _BSD_SOURCE
2006-03-19 18:06:32 +00:00
tg 94ee3b388a sync with OpenBSD: remove unused code and vars; name clash with libc
compiles under MirBSD
2006-01-29 20:04:54 +00:00
tg 95cfad6339 * only have one $MirOS RCS ID per file to shrink source size
(this is an exception from normal use)
* bump to R26
2005-11-22 18:40:44 +00:00
tg f38d8299f9 Change interpretation of '\"' in here documents with substitution
according to SUSv3 and other modern shells (POSIX allows both).
Idea for the patch (add another lex state) from OpenBSD, but the
implementation differs slightly (and is better in quality).

Also add two testcases (/bin/sh passes both, old mksh only one),
and document the change in the manual page. Sync RCS IDs with OBSD.
2005-11-22 18:36:20 +00:00
tg 9b97d72d5e * move _all_ #include stuff into sh.h
* sort out #include stuff which isn't necessary on MirOS into compat.h
2005-10-25 19:53:29 +00:00
tg df22a0fb1b Shuffle some stuff around to the compat functions and add glue 2005-10-25 19:46:11 +00:00
tg 2f9687c58a follow OpenBSD and add mknod as mksh builtin (mknod <file> p acts as mkfifo)
but write a good chunk of that code myself (better structured, better error
handling, more gotos, less function calls, int -> bool)

passes all tests on mirbsd; this will become mksh R25 once tested on other
supported OSes
2005-10-21 12:41:56 +00:00
tg 7ee8296628 our test(1) promises we can do string1 < string2, and
our /bin/test uses mksh... so we pee (literally) on
POSIX and don't accept < and > only for [[ ... ]] operator
2005-10-08 19:31:00 +00:00
tg 0651ba008e ^V now is quote, not version, even in emacs mode. (From OpenBSD.)
Also, the "version" command got removed in its entirety.
Shaves off another global variable, even.
2005-08-02 12:35:27 +00:00
tg ee7992988b * move <sys/param.h> include to sh.h

2005-07-04 12:34:24 +00:00
tg 3fb44287d4 mksh now does not look at $EDITOR and $VISUAL any more to determine
the editing mode; default is emacs (vi and gmacs off).
mksh also defaults to emacs-usemeta=OFF now.

* add declarations of strlcpy and strlcat (for GNU/Linux, again)
* always include <sys/resource.h>
* some more compile / warning fixes
2005-05-23 14:19:14 +00:00
tg cd7b8bd79b Add mirbsdksh R21, which was developed in a temporary external CVS repo-
sitory whose ChangeLog follows. mksh R21 is licenced under the MirOS li-
cence, shown in "sh.h", and a two-clause UCB-style licence by Marc Espie
as shown in "alloc.c".

This executable is a fair bit smaller and shorter than our /bin/ksh that
it is designed to eventually replace (as /bin/sh hardlink), with the old
/bin/ksh to completely vanish. It is still in beta testing though, and I
don't think it will compile on other operating systems.

mksh R21 is a completely new port, bringing together the OpenBSD-current
/bin/ksh, the MirOS-current /bin/ksh and the older mksh R20 (which still
was portable, ocvs-based).
