tg c187f3089f a tad annoying, when external programmes such as GNU screen are running,
we don’t get SIGWINCH when the window size changes during the runtime of
that, so, the signal is only usable reliably during editing in the shell
and we re-check the window size before each interactive edit line again

tg befbed2859 int → bool 2010-07-24 17:08:30 +00:00
tg c11d35312a Michal Hlavinka from Red Hat found another SIGSEGV
fix: when iterating over all Sources, know when to stop…
2010-07-21 11:31:16 +00:00
tg c6eedad976 *sigh* this code is interesting: assume you want to output via shf to
a string buffer whose window size is currently 32 (initial), your data
is 96 bytes, this routine used to resize the buffer to 64, append your
first 64 bytes to it (no matter if there's already something in it)
and then writes the remaining bytes to stdio fd instead of the string…
if it doesn’t SIGABRT before

discovered by wbx@ – thanks – bug inherited from pdksh 5.2.14 (AD 1999)
2010-07-19 22:41:04 +00:00
tg 7c91e018f4 • merge printf from OpenBSD
• deactivate %a and %A since our libc doesn’t have it
• rewrite the mksh integration code to use shf instead of stdio, removing
  floating point support always in the process, as shf doesn’t support it
  ⇒ saves 11114 (6706 text, 168 data, 4240 bss) with dietlibc on Debian
• fix -Wall -Wextra -Wformat -Wstrict-aliasing=2 for gcc (Debian 4.4.4-7)
• fix these and -Wc++-compat for gcc version 4.6.0 20100711 (experimental)
  [trunk revision 162057] (Debian 20100711-1) except:
  – a few enum warnings that relate to eglibc’s {g,s}etrlimit() functions
    taking an enum instead of an int because they’re too stupid to adhere
    to POSIX interfaces they design by themselves
  – all “request for implicit conversion” involving a "void *" on one side
• tweak the manual page somewhat more

tg 6b006202a1 partial oksh sync (RCSID and do add some parenthesēs to the list of

tg a6c81ea978 on obsd/mbsd, entropy is cheap enough for us to do this (codepath in

tg 2765a07564 when using persistent history (and not MKSH_SMALL), let the shells
concurrently accessing the same $HISTFILE be more synchronised with

tg 833810a154 While we were supposed to use Ctrl-Arrowkey for wordwise jumping,
some idiotic terminal emulators and/or people seem to use the es-
cape codes normally denoting Alt-Arrowkey instead so let's simply
bind them to the vt_hack as well... (untested)
2010-01-08 22:21:06 +00:00
tg 6115f5a91c • re-implement wcswidth-like behaviour for ${%foo} even in !UTFMODE

tg 417fd60c76 * fix 'set -A foo -- [2]=a b c' contingency (tested against GNU bash4,
which, in its latest sid incarnation, even received mksh's ability

tg a09f05e77a /me is annoyed
I read, IIRC in the Cederqvist, that 'cvs tag' sets a sticky tag onto

but one needs to know!)
2009-11-28 14:28:03 +00:00
tg 883d9d99b3 switch ${%foo} to wcswidth-like behaviour – slightly problematic, and
the “set +U” case isn’t even handled

committed to branch because I’d like to get more input on this, for now

tg 4cff10296b bump vsn 2009-11-22 14:25:18 +00:00
tg 2094e3f25c since we have wcwidth anyway, expose it as ${%strvar} to the user, iff
utf8-mode is enabled (otherwise it'll be a synonym for ${#strvar} aka
the number of octets in it)

tg fe853065bb make print_columns() aware that octets≠characters≠columns 2009-11-09 23:35:11 +00:00
tg 6fcacf577d make tab completing filenames with ':' '=' '$' '`' work as well as
others (colon and equals sign need to be simply escaped, while dollar
sign and accent gravis need double escaping like opening square brak-
ket did back then); add = to C_QUOTE to simplify (doesn't break any-
thing) and sort these strings asciibetically while here
2009-10-30 00:57:39 +00:00
tg dc98ec23a6 do not use PATH_MAX on GNU/Hurd (even if it *was* defined), but use
some glibc-only functions that don’t require its use instead

tested on gnubber, where (admittedly) sysconf(_PC_PATH_MAX) == 1024…

tg ceb591bf6a • better IV for the oaathash-on-binary (as if we prepended a '\x01')
• better variable name for the LCG state
2009-10-18 12:30:06 +00:00
tg eafe88aa74 • overhaul handling of special variables
• use a combination of the one-at-a-time hash and an LCG for handling
  the $RANDOM special if !HAVE_ARC4RANDOM instead of rand(3)/srand(3)
  and get rid of time(3) usage to reduce import footprint
• raise entropy state (mostly in the !HAVE_ARC4RANDOM case though…)
• simplify handling of the $RANDOM_SPECIAL generally
• tweak hash() to save a temp var for non-optimising compilers
• some int → mksh_ari_t and other type fixes
• general tweaking of code and comments

tg 549888a183 while testing haserl-0.9.26 on MirBSD, I discovered that the echo builtin
in FSH mode did in fact, contrary to POSIX and Debian Policy 10.4 behavi-
our (I think), interpret escape sequences; fix and add testsuite for echo

tg 73147a7fe9 fix lazy evaluation of assignments in ternary ops 2009-10-04 13:19:33 +00:00
tg 33b9f8b666 * rename "set -o posix" (FPOSIX) to "set -o sh" (FSH) because it's not
just a "somewhat more POSIX" but also a "/bin/sh legacy kludge" mode
* consistently capitalise POSIX and SUSv3/SUSv4 (same as AT&T ksh) and
  Bourne shell
2009-10-02 18:08:37 +00:00
tg ff8b75f46f SUSv4 says that there be exit 127; the old code tried but failed, so it
was an actual programmatical bug…
2009-09-29 12:28:13 +00:00
tg 7b7b75b026 * move the utf_* functions to a smaller file, to reduce the pain the
CPU has to endure while gcc is crunching on edit.c
* comment on mksh not using _exactly_ OPTU-8/OPTU-16 (XXX)
2009-09-26 04:01:34 +00:00
tg a59d14b565 further optimise and simplify the handling of $RANDOM, reads and writes
to it are now either arc4random or rand/srand, but srand retains the old
state; set +o arc4random is no longer possible, but if it's there we use
arc4random(3), if not, we use rand(3) for $RANDOM reads; optimise special
variable handling too and fix a few consts and other minor things
2009-09-26 03:40:03 +00:00
tg 1dfb13b603 change undef/def MKSH_NOVI into 0/1 MKSH_S_NOVI flag (with more to come:
MKSH_S_EDIT for small (Emacs) editing mode, MKSH_S_FEAT for all the dis-
abled language features), which can be set to 0 despite MKSH_SMALL being
defined to re-enable the Vi command line editing mode (which I wouldn't,
but fits into the general mastermind scheme)
2009-09-24 17:15:33 +00:00
tg 1a28786229 * shrink MKSH_SMALL even further by removing functionality like
some GNU bash extensions (suggested by cnuke@) and bind macros
* make the random cache more efficient (and the code potentially
  smaller, although we have a new implementation of the oaat hash
  function, alongside the old one, now) and pushb only if needed
  (i.e. state has changed or user has set $RANDOM, but not onfork)
2009-09-23 18:04:58 +00:00
tg 1ea1096a4e Add a hack input function for VT100-style key sequences; support
Ctrl-CurLeft and Ctrl-CurRight (not quite ANSI, but fits the scheme)
2009-09-20 17:23:52 +00:00
tg 588921333e more of this:
• shell flags are now handled in one single place (sh_flags.h)
• sync comments (between enum and array) and manpage with reality
• FMONITOR is now no longer needed for Hartz IV shells

tg 9dd98da40d Support Dave Korn’s alternative 「'a'」 (or 「'…'」) form for base-one
integers in addition to my 「1#a」 (or 「1#…」), which also allows for
finer end-of-character checking. Note that this is locale-dependent in
ksh93, set ±U dependent in mksh, and mksh’s OPTU-16 encoding is used.

2009-08-30 13:30:08 +00:00
tg 31e02e59f7 add a do_realpath() implementation replacing the use of the external
libc function realpath(3) which may not be available on the target
system; compile the realpath builtin unconditionally

looks fine to me, but review is appreciated; this is (very) lightly
based upon MirBSD libc’s realpath(3) and pdksh’s get_phys_path()

tg 9b8d4023fa … but since I liked the bonus of having the hval stored so much, merge
it with the array index; var.c says that
│ 1244         /* The table entry is always [0] */
so that we can have a special flag and a union which stores hval for
the table index, the array index otherwise (coïncidentally *hint hint*
they have the same size)
2009-08-28 21:01:27 +00:00
tg bb7a720a00 for now, until we really use kt*() otherwise, ifdef out tablep/hval 2009-08-28 20:38:43 +00:00
tg 4ccdfc8508 much better solution: save tablep and hash value¹ in the struct tbl entry
① also saves time during texpand :D

XXX this doesn’t work well with the current indexed-array implementation
2009-08-28 20:30:59 +00:00
tg 7240c843ce this is a rather stupid diff: give ktsearch/ktenter the capability to
return information needed to do a real ktremove instead of the pseudo
ktdelete operation which merely unsets the DEFINED flag to mark it as
eligible for texpand garbage collection (even worse, !DEFINED entries
are still counted)

• optimise ktsort()
