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.

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.

Unfortunately (as I expected) the previous change broke:
...
sleep
cmd='set `type "sleep"`; eval echo \$$#'
which=`eval $cmd`
echo $which
because the region did not get recorded at all, and it was interpreted as
a single word. I modified the code to keep track when the result of a
backquote expansion has been recorded to avoid recording it twice. I still
feel that this is not the right fix... More to come.

anything else.

Fix problem introduced in yesterday's commit that broke both signed and
...
unsigned character machines. So that people don't have to reverse engineer
this again:
mksyntax detects if characters are signed or not and builts a syntax
table that has a base of 129 for signed characters or 1 for unsigned
characters. This is so the largest negative signed char [-128] + the
base == 1. 0 is special and means end of file in both cases. PEOF
is -1 for the unsigned character case and -129 for the signed
character case, so that syntax[PEOF + base] == syntax[0] == CEOF
So PEOF has to be -1, but it is explicitly compared with
unsigned characters on machines where characters are unsigned.
The quick fix is to define UPEOF the (unsigned char) version of PEOF
and use that. A better fix is to always use unsigned characters
when referencing symbol table entries, but that would require
extensive changes to the shell. So to summarize
syntax[0] == CEOF, base + PEOF == 0
unsigned signed
base 1 129
PEOF -1 -129
