tg 757e25fb21 implement $KSH_MATCH and, to make it usable, ${foo@/bar/baz};
add a real-life example (for slagtc’s programmable tab completion)
to the manpage

tg f9d131133e remove fd>9 support in favour of upcoming named file descriptors; bump 2016-07-25 21:05:25 +00:00
tg c3e794c4d0 rework string pooling; disable our own (rely on compiler’s)…
• if HAVE_STRING_POOLING is set to 1
• if HAVE_STRING_POOLING is set to 2 and not GCC < 4 is used
• if HAVE_STRING_POOLING is not set to 0 and LLVM or GCC >= 4 is used

Closes: LP#1580348

tg 262ae5a436 fix most of the ambiguous ${[prefix] var [op [word]]} corner cases
prodded by izabera and carstenh; resolution is:
• you can’t trim a vector in mksh, still (consider ${@:-1})
• future POSIX will require non-empty “word” for most “op”s
• dissolve in order of standard → extension
• dissolve to prefer “op” over “prefix” where still necessary, mostly
2016-06-25 23:55:00 +00:00
tg 3d130b606a give C_VAR1 precedence over display variable name; izabera pointed out,
rightfully, that, in POSIX shell, ${!#} is defined, and ${!#123} should work

tg 4c4131dddf commitid 10056D5D8AF01B31531 broke fix for Debian #783978 (add testsuite) 2016-04-09 13:55:12 +00:00

tg c2bdb1b9dd check not-begun heredocs at EOF earlier
izabera reported they were not caught with “set -n”

tg 046d8e5b7a align with future POSIX on http://austingroupbugs.net/view.php?id=351
with accepted interpretation (*sigh*); merge VARASN|ARRAYVAR→CMDASN

tg 44be0bdb0b deliberately revert from POSIX to classical behaviour for "…`…\"…\"…`…"
until http://austingroupbugs.net/view.php?id=1015 is resolved (either way),
mksh R52 regression; cf. Debian #810846, #811092

tg af35e9a6de revert most of commitid 3ec342c92b3a8874 and fixup the rest;
this should bring us closer to POSIX again

tg 3fc8b5eb94 partial oksh sync, up to commit 80be547da108d5c241ae068290ca3e331446aa41? 2015-10-09 16:11:19 +00:00

tg 609b311919 more low-hanging fruits for EBCDIC; notes:
• ord() new, From: Daniel Richard G. <skunk@iSKUNK.ORG>
  ‣ used in some places
• (c - '0') → ksh_numdig(c)	# may take *x++ argument
• (c - 'A') → ksh_numuc(c)	# may NOT take *x+= argument
  ‣ idem for ksh_numlc(c) and 'a'
  ‣ these need changing for EBCDIC
  ‣ add testsuite for this
• use macros more, they exist already often
• use digits_lc[foo] instead of ('0' + foo), especially for letters
• caught another ksh_eq case…
• also caught a maybe-UB overflow check, but we don’t have TIME_T_MAX ☹
2015-04-29 20:07:35 +00:00
tg 65f9b93926 ordinarily, lineno must be mksh_uari_t, but edit.c most of all isn’t ready,
so we mitigate a bit (in var.c mostly) and tweak another type already, and
add some checks (mksh_{,u}ari_t must fit into {,unsigned }long) and print
line numbers with %lu already

tg e1cda74d04 SECURITY: fix integer overflows related to file descriptor parsing
bug initially found by Pawel Wylecial (LP#1440685)
additional bug found and suggested fix by enh (elliott hughes)

This commit also renames struct ioword.flag to ioflag to disambiguate
it from other members named “flag”, changes it to an unsigned type,
and packs ioflag and unit into shorts each, to make the struct smaller
(aligned even: 16 bytes on 32-bit systems) and reviews some of the
code involved in fd handling, though there wasn’t much to be found.

2014-01-11 18:09:43 +00:00
tg 2f7eec765d merge oksh’s “ctype cleanups” commit
(not much of it applies since we don’t use the OS’ table-based lookup)
2014-01-05 19:11:46 +00:00

tg 5eb6995d75 Ypnose discovered a problem with multi-line prompts and SIGWINCH
related to caching some values (downside, pprompt gets back doprint option)

tg c10e5bd237 reduce amount of .bss memory needed; initialise via AEDIT at x_init
or even first run of x_vi
2013-08-10 13:44:33 +00:00
tg 247e20c524 • Completely overhaul prompt length calculation and
prompt display routines; make Emacs and Vi share
  code, permitting reducing of duplication and code
  removal as well as more consistent behaviour; put
  some common code into shared helper functions, too
• New x_adjust() logic (Emacs mode): when determining
  what portion of a line to render use a much more
  sophisticated algorithm and try to fill up ⅔ of the
  total screen width (with line and prompt both) also
  as wished from Steffen Daode Nurpmeso

tg ea657bd4d9 also do not, ever, use &> bashiop in lksh 2013-03-29 17:33:56 +00:00
tg a3b5e77c6c disable parsing of &> as GNU bash iop if -o posix or -o sh, based on IRC discussion where jilles(IIRC) pointed out it breaks existing valid scripts 2013-03-24 15:01:50 +00:00
tg 74e2ef8b0b one more int → bool; mention “set -o sh” may (on raare OSes) be enabled
automatically (and it differs between targets); test MidnightBSD 0.1 ash
compat code and adjust the testsuite so it passes with it enabled
2013-02-19 18:45:22 +00:00
tg e21a2166f7 use a different approach to the $"…" problem:
take the states that may open a string, only permit them by virtue of
moving the code out of Subst: to handle $+" and $+' at all; then add
S[Q]BRACE to that

side benefits:
• clearer, cleaner code flow
• smaller code
• better “business logic” ☺
• defuses one heavy use of duff’s device a bit
2013-02-17 06:05:02 +00:00
tg b684a7c6bd backpedal with $'…' and $"…" interpolation
it turns out this breaks more legacy scripts than anticipated
2013-02-17 05:40:17 +00:00
tg 1da94d6159 pure RCSID sync with oksh, who also added a tabcompletion fix now, with
less code, but, even according to their own comments, not as good as ours
