* Fix child's SIGSTOP behaviour in scripts.cracauer2001-02-061-1/+2
| | | | | | | | | | | | | | | | | | When a child is receiving SIGSTOP, eval continues with the next command. While that is correct for the interactive case (Control-Z and you get the prompt back), it is wrong for a shellscript, which just continues with the next command, never again waiting for the stopped child. Noted when childs from cronjobs were stopped, just to make more processes (by wosch). The fix is not to return from a job wait when the wait returned for a stopped child while in non-interactive mode. This bahaviour seems to be what bash2 and ksh implement. I tested for correct behaviour for finnaly killing the child with and without forgrounding it first. When not foregrouding before killing, the shell continues with the script, which is what the other shells do as well. Reviewed by: Silence on -current

* From submitter:cracauer2000-08-163-1/+22
| | | | | | | | | | | | | | | | | growstackblock() sometimes relocates a stack_block considered empty without properly relocating stack marks referencing that block. The first call to popstackmark() with the unrelocated stack mark as argument then causes sh to abort. Relocating the relevant stack marks seems to solve this problem. The patch changes the semantics of popstackmark() somewhat. It can only be called once after a call to setstackmark(), thus cmdloop() in main.c needs an extra call to setstackmark().
