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 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 4adcfe8b58 oksh sync, simplify *all* if(x)free(x); constructs, simplify x_push() and sync boilerplate while here 2015-09-05 19:19:12 +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 9d30e9c9d6 oksh sync: one rcsid-only plus this one by guenther: 
Zero-pad the seconds in the output of 'time' to make columns line up
 2015-08-13 21:04:12 +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
tg 950827394b more easy OS/2 fixes 
From: KO Myung-Hun <komh@chollian.net>
 2015-07-09 19:46:43 +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

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 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 7f48503c66 sometimes, I feel pretty stupid 
separate the backslash+newline things out of the *.opt files,
logically not 100% clean, but better as it is not generated
content anyway (keeping the one-liners in there for now, even
though more consistent would be shifting them out as well)
 2015-05-01 23:16:31 +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 c3efd2abb2 use already-existing ksh_isdash helper macro 2015-04-29 18:32:44 +00:00
