tg 8370c0dd4d experimentally use MKSH_CLRTOEOL_STRING instead of lots of spaces followed

tg 9ab9ee194c fix shf.c-internal buffer overread on printing digits, 
introduced by the utf_skipcols()-related fixes, more

tg f0a042f070 implement mmap-using mechanism to catch buffer underruns inside mksh

 2016-02-24 01:44:46 +00:00
tg 7c58621bc7 so, GCC is a real bitch 2016-01-21 19:58:13 +00:00

tg b2b0c0bbb6 update for recent changes 2015-12-12 22:25:15 +00:00
tg 1a4f644d6e save ~1½K from the bootfloppy by reusing MirBSD libkern wcwidth(3) 
but don’t bother for this for the regular /bin/mksh either
to keep the generic code path tested well
 2015-10-24 19:45:23 +00:00
tg cef386fb60 make “source” into a built-in command (keepasn, to match ksh93 and “dot”); 
remove the “stop” alias and drop old Android and OS/2 hacks and auto-unalias
 2015-10-09 21:36:59 +00:00
tg fc48729336 tweak some iop/conservative_fds-related things I picked up while thinking lksh 2015-10-09 19:29:50 +00:00
tg af35e9a6de revert most of commitid 3ec342c92b3a8874 and fixup the rest; 
this should bring us closer to POSIX again
 2015-10-09 17:48:53 +00:00
tg 3fc8b5eb94 partial oksh sync, up to commit 80be547da108d5c241ae068290ca3e331446aa41? 2015-10-09 16:11:19 +00:00

tg 1b8b792b7e quote path separator if ; in some cases; pointed out by komh 2015-08-13 22:06:23 +00:00
tg c674e71377 be more careful with signals and errorlevels; bounds-check them better; 
don’t trust the OS as POSuX comes up with more-than-8-bit exit codes now;
also, one more int → bool
 2015-08-13 21:38:19 +00:00
tg ba8a6e9461 merge OS/2 style PATH (absolute with drive letters, ‘;’ as separator) 
From: KO Myung-Hun <komh@chollian.net>
 2015-07-10 19:36:38 +00:00
tg edf76ec8e6 harden the crlf vs lf tests even more; use binary mode explicitly on OS/2 2015-07-09 20:52:43 +00:00
tg dcd8b6389b apply the new cat hack to printf, too, to prefer it over the builtin 2015-07-09 20:20:45 +00:00

From: KO Myung-Hun <komh@chollian.net>

tg 041666eefb a few more mksh-os2 inspired fixes 2015-07-09 19:28:21 +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
 2015-07-05 19:37:18 +00:00
tg 62e27c3e07 simplify print_columns func argument: no need to return the first arg any more 2015-07-05 14:43:08 +00:00
tg 7a1acedd4a bump; nothing to merge from oksh, and nothing more from me today 2015-06-28 16:23:24 +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
 2015-04-29 20:44:37 +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 3eb806b72b inline only user of ksh_min, make it more cool; drop ksh_min, ksh_max; 
move ksh_isdigit etc. to ksh_isalpha etc. definitions
