In current implementation of busybox timeout utility, when a signal is sent to the process that needs to timeout, it does not affect the children. To fix this we set the process group id of the process that the signal is sent, same as it's pid, making it the process group leader. When sending signal, we sent it to negative pid number as per man page and signal is received by all children.
That is a very disruptive change that modifies the semantics of 'timeout' entirely, and that leads to unintuitive behaviour for instance wrt ^C when used in a terminal. Well-behaved programs should never need signals sent to the process group, and when a utility does that it should be *very obvious*. At the very least, if the functionality is implemented, it needs to be configurable via a command-line option. -- Laurent _______________________________________________ busybox mailing list busybox@busybox.net http://lists.busybox.net/mailman/listinfo/busybox
