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

tg 1a4f644d6e save ~1½K from the bootfloppy by reusing MirBSD libkern wcwidth(3)

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”);

tg af35e9a6de revert most of commitid 3ec342c92b3a8874 and fixup the rest;

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)

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 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

tg 2cb0ea982a EBCDIC helpers and OS/390 signals 2015-04-29 18:38:54 +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)
including ASan (testsuite) and Valgrind (short)
2015-04-19 19:18:07 +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
2015-04-19 18:50:38 +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 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.
