tg b531baa7fd add a “\builtin” builtin, make it forward assignments, fix some bugs 
related to that:
• while AT&T ksh may do it, POSIX says nothing about allowing
  declaration commands only without vars and redirections, and
  “without vars” especially seems against which commands they are
• fix relationship between forwarders and real declaration commands
• clean up c_builtin vs shcomexec mess

Also, re-run “make repool” with a fixed src/scripts/stringpool.sh,v 1.3

tg c3e794c4d0 rework string pooling; disable our own (rely on compiler’s)… 
• if HAVE_STRING_POOLING is set to 1

• if HAVE_STRING_POOLING is not set to 0 and LLVM or GCC >= 4 is used

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 b9a8fdf905 implement cat thing for realpath and rename too: if flag, call external 2015-07-05 15:45:18 +00:00

tg cad9bc86d3 Implement the “FKSH functions have local scope for shell options” feature 
for mksh but not lksh; bump to R51-alpha.

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.

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 1248a0a521 basically unbreak use of $*/$@ in here documents 
a bit funny:
