tg fd37f4baf0 POSIX doesn’t like the OPTU encoding scheme due to btowc/mbtowc asymmetry,
so make all utf8-mode behaviour implementation-defined (and document the
raw octet mapping more explicitly)
2015-07-10 19:35:39 +00:00
tg 0fd9337123 implement support for PC scancodes à la CHR$(0)+CHR$(&h48)
superseding an mksh-os2 patch which confirmed this is needed

Microsoft® GW-BASIC

tg dcd8b6389b apply the new cat hack to printf, too, to prefer it over the builtin 2015-07-09 20:20:45 +00:00
tg 483536e336 point out mknod is not normally part of mksh either 2015-07-09 19:50:44 +00:00
tg f463d9da76 • revert the cat hack for realpath and rename
‣ I was convinced by several that more magic is never the solution
• fix a comment: function cat already had precedence
• change cat loader to look for existence, FPATH included, before
  ditching the builtin; note that in manpage
2015-07-06 17:48:37 +00:00
tg e0196f47d5 implement completely new multiline code by delaying history store
this commit is valgrind-tested

tg 48af854117 fix 'command -v' for "shell reserved words"
From: Martijn Dekker <martijn@inlv.org>

also adjust manpage accordingly

tg b478d334d9 merge spelling stuff from oksh 2015-07-05 15:22:41 +00:00
tg 0bdc395a81 permit read -N n (n ≠ -1) and read -t to return partial reads with $? == 1
issue spotted by carstenh, could have been a documentation ambiguity issue
(as -N was designed to read and return exactly n bytes), but this resolves
it in a way both backwards-compatible and user-pleasing
2015-06-28 14:57:25 +00:00
tg babd9c4cf0 The check for empty patterns and patterns matching the empty string
in commitid 1004D8283F068C41C3C was bogus; it fixed Jb_boin’s issue
but izabers’s 「var=foo; echo "${var/*/x}"」 was broken; in fact we
only want to not do the looping for // if the pattern matches much.

Also, fix a spelling mistake in the manpage and change some wording
to also work with associative arrays (in the future; no change).
2015-05-23 17:43:22 +00:00
tg 93ccb42114 overhaul the signal handling:
• support NSIG_MAX from http://austingroupbugs.net/view.php?id=741
  and make a TODO for later to use sysconf(_SC_NSIG) at runtime
• bounds-check signals (e.g. no smaller than 1, but smaller than NSIG)
• align trap errorlevel with other shells
• make trap match what’s in POSIX and fixup the manpage
• refactor some code related to signals
• hide from kill builtin both EXIT and ERR pseudo-signals

tg 4a33198f45 manpage fixes (mostly \-x to Fl x inline) 2015-04-29 20:13:26 +00:00
tg 0661df9940 fix lies; this had to be taken out for security reasons some time ago 2015-04-29 18:56:00 +00:00
tg 82bc5eba9a give a better suggestion: find|read → find|&read 2015-04-29 18:54:05 +00:00
tg c9ccf0bab7 MFC remaining fixes; tested locally a lot, plus remotely with
GNU C11 (Debian 20150413-1) version 5.0.1 20150413 (prerelease) [gcc-5-branch revision 222050] (x86_64-linux-gnu)

tg 4bea0cc227 MFC most things (see mksh.hts) to R50-stable; sync clog 2015-04-12 22:32:12 +00:00
tg cad9bc86d3 Implement the “FKSH functions have local scope for shell options” feature
for mksh but not lksh; bump to R51-alpha.

While here, tweak build scripts a bit, fixup MirBSD-specific Makefile
things, remove part of a comment that’s uninteresting.

tg 6b00977053 just another oksh rcsid-only sync (we bind to the Delete key since forever) 2015-04-11 22:09:49 +00:00
tg 0620a5d034 sync clog 2015-03-21 00:12:46 +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…

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 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

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

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 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 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

tg f66c194f29 oksh sync RCSIDs only:
• expr.c long done already
• mksh.1 does not apply to us (no character classes)
