tg 034d0c0269 fixup “\builtin” on OS/2; thanks komh for spotting this 2017-03-22 00:20:53 +00:00
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

KO Myung-Hun f814ccfb8f exec: remove the last / or \ when searching $PATH 
For example, X:/ becomes to X://name. CMD.EXE is not tolerant of such
a style.

KO Myung-Hun bf88879b0d Revert "exec: prevent a command in a current dirctory from being executed" 
This reverts commit 1b4d572b77.

An empty path is treated as a current directory in Unix, too.

KO Myung-Hun 1b4d572b77 exec: prevent a command in a current dirctory from being executed 
A command in a current directory should be executed only if $PATH
contains the directory such as '.'.

This will improve the compatibility with Unix shell script and the
security.

KO Myung-Hun eb43e28996 Revert "exec: search commands in the current directory first on OS/2" 
This reverts commit 89d461dd83.

To avoid the incompatibility with Unix shell scripts not expecting that
a current directory is searched first and the security problems, let a
user prepend "." to $PATH explicitly if needed.

KO Myung-Hun 89d461dd83 exec: search commands in the current directory first on OS/2 
On OS/2, commands(executables) are searched in the current directory
before in $PATH.
