Jon Siwek 1531980f3d Exec module and raw input reader fixes. ... - Do stream mode for commands done by exec module, it seems important in some cases (e.g. ensure requested stdin is fully written). - For cases where the raw input reader knows the child process has been reaped, set the childpid member to a sentinel value to indicate such so we don't later think we should kill it or wait on it anymore. - More error checking on dup2/close calls. Set sentinel values when closing ends of pipes to prevent double closing a fd. - Signal flag not set when raw input reader's child exits as a result of a signal. Left out a test for this -- might be portability issues (e.g. Ubuntu seems to do things different regarding the exit code and also is printing "Killed" to stderr where other platforms don't).		2013-08-02 17:27:10 -05:00
