tg 3c5c5d02fd fix IFS='\' issues, found by edualbus (Eduardo A. Bustamante López <dualbus@gmail.com>) 2015-04-11 21:18:47 +00:00
tg 4ee3269564 • the \: "${foo:=bar}${bar:=baz}" construct needs no spaces 
• more set -u police
• 80c and tweaks while here
 2015-04-11 19:01:59 +00:00
tg 451aef7a8a some robustness improvements for dot.mkshrc: 
• do not use \return for return before we know we are mksh
  (plus fix a wrong-word mistake)
• quote the argument(s) to \: (“colon”) for SECURITY
• default $MKSH to /bin/mksh (not normally reached)
• while here: check $USER only once, not for each PS1 (speed)

this addresses and mostly closes LP#1441853 – prt.mkshrc (in
OBS home:mirabile/mksh and DEB wtf-mksh they are identical)
is already good; Android mkshrc needs only some small robustness
fixes (mostly colon-related; enh says TMPDIR is good); I tested
this with “mksh -eu” and “mksh -eul” on Debian and ecce and with
read-only “/” and nothing else mounted on ecce, and it WFM
 2015-04-11 18:08:56 +00:00
tg 0620a5d034 sync clog 2015-03-21 00:12:46 +00:00
tg 07898d8a45 only lksh now implies unalias for a POSIX function definition (used e.g. in Debian sysvinit scripts that use a “stop” function) 2015-03-20 23:37:55 +00:00
tg 8641829e21 fix comment no longer true since commit 1004DC49710562ACCB2 2015-03-20 23:37:39 +00:00
tg 0947d274f6 use a perl test for fd-cloexec to avoid testing the tester with the tester; improve fd-cloexec description 2015-03-20 23:37:29 +00:00
tg 1351c5eb0f permit building lksh with printf builtin, for testing 2015-03-20 23:37:17 +00:00
tg 2097d45f7f oksh rcsid-only sync, plus bonus rewrite of strip_nuls 
(uses size_t ipv int for buffer size now, and no extra
calls to memchr/memmove, input is typically small)
 2015-03-20 21:46:41 +00:00
tg 8967f13bc6 oksh rcsid-only sync, plus a fix in the commit whose body I skipped 
sync’ing, plus a bonus fix inspired by their commits in sh.1…
 2015-03-20 21:23:52 +00:00
tg 5c5fb404b1 fix “read -n-1”, which still returns once the first read() succeeds 
(it’s not identical to “read -N-1”!)
 2015-03-20 21:01:41 +00:00
tg 0d72355038 “local x=$1” is supposed to not field-split and so 2015-03-14 05:23:18 +00:00
tg 532af35304 oksh rcsid sync; we have no set -o csh-history, and the manpage changes are just wrong, so, a nop 2015-03-14 05:17:17 +00:00
tg bcff0752b4 another needed quote 2015-03-14 04:38:13 +00:00
tg 96d9e5d1f1 remove unused CMDWORD 2015-03-14 04:37:55 +00:00
tg f893c7a347 implement “enable” (like GNU bash) to stop Harzilein from complaining 
about mksh’s “rename” builtin
 2015-03-08 23:50:00 +00:00
tg 8f53c68265 • protect POSIX builtins and utilities from aliases, e.g: 
‣ : → \:
  ‣ alias → \alias
    ⇒ except in some internally used cases, where we use \builtin alias
  ‣ command . → \command .
• protect Korn Shell builtins from aliases and functions, e.g:
  ‣ typeset → \builtin typeset
    ⇒ also unravels the “local” alias used
  ‣ print → \builtin print
• protect internally-used things from aliases
  ‣ “let]” is not a valid function name
  ‣ “set” is POSIX so we don’t expect anyone to override it in a function
• use “command -v” instead of “whence -p” (“which”) in most
  places; thanks izabera from #ed on IRC for pointing out
  that “command -v” is POSIX – except, “whence -p” a̲l̲w̲a̲y̲s̲ looks
  for an executable and shows its full pathname; “command -v”
  also resolves to aliases, functions and builtins, so only use
  it where it makes any sense (both never output to stderr)
• make most of dot.mkshrc work in the face of such aliases
  ‣ “ulimit -c” is used; this is not POSIX, and not portable;
    maybe we should make ulimit accept-and-ignore the most
    common limits even if the OS doesn’t use them?
• update list of builtin aliases in the manpage
 2015-03-08 22:54:36 +00:00
tg fcc59eee48 remove some unused string pooling stuff 2015-03-08 21:30:22 +00:00
tg be147e3426 SECURITY: make “unset HISTFILE” really work 
additionally, make “HISTFILE=” the same, document the truncation and
re-reading process’ further and already-known bugs; this needs work
 2015-03-07 20:46:31 +00:00
tg d3f3c3ec22 it’s probably useful to define a marker like this, for automated patching, 
e.g. in SuSE’s shells/mksh specfile, since they insist on a vendor patch,
as PLD does
 2015-03-05 13:30:57 +00:00
tg 8546943535 KNF 2015-03-01 16:02:48 +00:00
tg e3acd9c76a MFC everything except the igli-inspired changes to jobs.c and the 
.Ox Ns -inspired integer base changes .
That means: bugfixes, plus the new arguments to exec (feature)
 2015-03-01 15:43:09 +00:00
tg 707add559f keep “set -x” disabled during PS4 expansion, to avoid infinite looping 2015-03-01 15:23:05 +00:00
tg 06045cf889 more IRC deliberation with igli (let’s hope the “const” works), plus style advice from Kernighan’s writs 2015-02-20 13:08:28 +00:00
tg 5efc48befd optimise a bit (nuke one redundant check), from igli via IRC 2015-02-20 12:43:22 +00:00
tg f4ae6f7508 can't set word=IFS_QUOTE if already IFS_WORD (something there) 
or IFS_QUOTE (third dquote (second OQUOTE) in """something)
 2015-02-20 07:14:30 +00:00
tg 73082b9292 • fixup here document expansion (regression wrt. pdksh 5.2.14) 
• adjust testsuite (and write tons of new tests) after today’s commits
 2015-02-19 22:26:50 +00:00
tg be1a0e3282 unbreak other cases where $@ shares double quotes with something else 2015-02-19 22:01:13 +00:00
tg 1248a0a521 basically unbreak use of $*/$@ in here documents 
a bit funny:
with NUL IFS, $* behaves like dash ('ab') and $@ like bash/ksh93 ('a b')

with WS or NWS IFS, all shells behave alike though
 2015-02-19 22:00:03 +00:00
tg ab683420df fix use of $*/$@ in scalar context in [[ … ]] and case; spotted by Stéphane Chazelas 2015-02-19 21:58:19 +00:00
tg 61cea6b71b another oksh rcsid-only sync 2015-02-16 15:10:15 +00:00
tg 4157cca352 oksh sync; unsure if it applies (with us using old_source and all) but 
better be safe than sorry; it at least passes our testsuite

NOTE: people who can figure out how afl can be used for mksh welcome! ;-)
 2015-02-13 12:51:33 +00:00
tg f6f49a119b add getopts for exec (unbreaks “exec -- /bin/ls”) and steal -a and -c from ksh93 2015-02-06 10:56:49 +00:00
tg b94b2e363a stop (ab)using the OS symbolic constant EOF, always use -1; plus misc fixes 2015-02-06 10:09:07 +00:00
tg f235766a3d int → bool 2015-02-06 09:42:46 +00:00
tg 3be80b75ed remove dead code: this can no longer happen since exec.c,v 1.67 2015-02-06 09:42:08 +00:00
tg 6f3d362785 rewrite the code a bit to avoid GCC -Wstrict-overflow triggering in one case… 
most of it is utterly useless though as the line indicated is usually the
closing curly brace of a function, often not even the reported one…
 2015-02-06 09:33:41 +00:00
tg 934929c2ee rcsid sync from obsd; misc sync; small improvements 
• mksh testsuite no longer uses printf, again
• use MAXPATHLEN from <sys/param.h> as PATH_MAX fallback
 2015-01-25 15:23:43 +00:00
tg d5bdd0e364 fixup mergo from cid 10054762AC33B0CB0D0 2015-01-22 16:54:29 +00:00
tg 59fcff27ae • fix bug spotted by geirha: typeset args are glob-prone 
• ormaaj suggested adding gsf’s homepage (still no new ast-ksh)
 2015-01-11 00:23:06 +00:00
tg d048818dfa • when using typeset to change the type of an array, 
use arrname[*] to denote changing it of all array elements
• optimise a bit: group local invocations
 2015-01-06 20:54:53 +00:00
tg e49d7bc3c6 better 2015-01-04 21:08:10 +00:00
tg a56f5ccbc4 fix mksh regression: empty line after “whence -v” with not found 
spotted by Ypnose via IRC
 2015-01-04 20:37:59 +00:00
tg 8f40b65df9 add an Ohcount modeline to recognise this as sh file 2015-01-04 20:23:51 +00:00
tg 51c370459e bump version and, also, year… I hate this… 2014 is gonna follow us for a while… 2015-01-02 13:21:28 +00:00
tg 7b4951c58f apparently, we’re supposed to setuid() before seteuid() 
cf. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=772597
also, groups before users, methinks…
 2015-01-02 08:18:44 +00:00
tg e60f3e494b future directions 2014-12-18 20:51:12 +00:00
tg f66c194f29 oksh sync RCSIDs only: 
• expr.c long done already
• mksh.1 does not apply to us (no character classes)
 2014-12-15 23:26:36 +00:00
tg 5650b03590 OpenBSD RCSID merge, and logical follow one change: 
handle unknown bases as ksh93 does: larger downgrade to 10
(although our max will stay 36, as ksh93 doesn’t have upper/lowecase)
and smaller downgrade for typeset -i, but not for arithmetics
 2014-12-15 23:18:47 +00:00
tg dcdc828c41 fix here string parsing problem found by Stéphane Chazelas 2014-12-15 22:50:11 +00:00
