elric f5dccf4728 When vforking ensure that the environment passed to exec is built before
vforking as a set of local variables which can be popped by the parent.

mycroft 2806df576c It turns out that the code disabled in revision 1.30 *does* have an important
function (which nobody was able to explain): it's critical to allowing a
complex command run from an interactive shell to be terminated.  So, reinstate
it and fix it correctly.  See the comment if you really want the gory details.

itohy 362c3e31c9 The builtin . (dot) command no longer sees the current working directory
even if the specified file is not in the PATH.
This change enforces security and makes it conform to POSIX.

Closes PR #6794.
I thought Christos committed this but not appeared yet. :)

The setstackmark()/popstackmark() pair in dotcmd(), used for freeing
stack storage possibly allocated by find_dot_file(), is redundant for now
since dotcmd() is surrounded by another pair in evalcommand().
This redundancy, however, may help future modifications
(suggested by Christos).

christos e1849b79b1 PR/6213: Urban Boquist: /bin/sh does not handle a trapped signal correctly
The problem was that system calls got restarted after a signal,
	 instead of returning EINTR. Thus the read builtin, had no way to
	 know that a signal occured that could change the course of execution.
	 Since the code has sprinkled checks for EINTR all over the place,
	 it is supposed to work properly with non restartable syscalls.
	 The fix is to use siginterrupt(signo, 1), before setting a signal
	 handler, to make sure that system calls don't get restarted.

garbled f33f4be925 Massive fixup:
Rewrite man page in mandoc format rather than nasty man format.
Fix a ton of parsing errors, and generate proper .Xr's.
document all known environment variables.
suggest ksh rather than bash.

The last two fix PR #1966.  Wheee!

Somebody with access to the POSIX spec needs to go in here, and document
our adherence, or lack thereof.

itohy ef88b5d2bd Fixed memory leak on old style command substitution
such as  sh -c 'echo `echo foo`' .
The memory allocated with ckmalloc() at
parser.c:1349:readtoken1() (search for "done:" label)
was never freed.

I changed this to use 'string stack' framework of Ash.
Note that a string on string stack is properly freed on
exception and end of command parsing, and no explicit free
or signal handlings required.
See TOUR for an overview, and memalloc.[ch] for details
of string stack.
