xgetcwd, but did not check the return for a NULL, and then continued
to call strlen on the NULL when the cwd had been removed from under it.

This way leaks memory, but oh well. We will probably fix that when we get
around to doing local variables.
|
|
Update some comments. Generate partial placeholders for the missing
builtins. Write builtin_umask. Properly treat exec without arguments
as a means to open/close files within the running script. Implement
"4<&-" that encodes for file descriptor closure.

trying to make job control work. This fix makes it so that
hush doesn't error out when init hasn't set up job control,
as in when init=/bin/sh

in place, but something is still missing/wrong in there. Testing with
'grep foo &' seems to put _hush_ into the background. Pondering...

Fixes bizarre suspension when executing `echo`.

Makes hush return code equal to that of the last command executed.
Fixes the mode where input comes from a file.

Minor improvements. Something is still broken with running
scripts via "hush filename". All the following are now handled
acceptably (matches ash, not bash).
if true; then echo foo1; fi
if
true; then echo foo2; fi
if true; false; then echo bar; else echo foo3; fi
if true || false; then echo foo4; fi

It should recover more smoothly from syntax errors, and it now
has a decent guess when the reserved word construct is over
(or not) to control execution and prompting. I took out all the
redundant standalone test copies of libbb routines, but left in a
hook so I can include those for my testing. I'll post that include
file on my web site.

April 25, 2001 snapshot, adjusted a bit by me so it has cmdedit support.
This checkin also removes sh.c. In the future sh.c will be a symlink to
your shell of choice. For now, this symlink will default to pointing to
lash.c (as in the past). If you change the symlink to point to hush.c,
then thats what you will get. This symlink business is a temporary situation,
which will be cleaned up Real Soon Now(tm).
