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
This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you have to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/i386/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
