With this change, a simple + mechanism is implemented to make ">>" work in action lines. In VMS + there is no simple feature like ">>" to have DCL command or program + output redirected and appended to a file. GNU make for VMS already + implements the redirection of output. If such a redirection is detected, + an ">" on the action line, GNU make creates a DCL command procedure to + execute the action and to redirect its output. Based on that, now ">>" + is also recognized and a similar but different command procedure is + created to implement the append. The main idea here is to create a + temporary file which collects the output and which is appended to the + wanted output file. Then the temporary file is deleted. This is all done + in the command procedure to keep changes in make small and simple. This + obviously has some limitations but it seems good enough compared with + the current ">" implementation. (And in my opinion, redirection is not + really what GNU make has to do.) With this approach, it may happen that + the temporary file is not yet appended and is left in SYS$SCRATCH. + The temporary file names look like "CMDxxxxx.". Any time the created + command procedure can not complete, this happens. Pressing Ctrl+Y to + abort make is one case. In case of Ctrl+Y the associated command + procedure is left in SYS$SCRATCH as well. Its name is CMDxxxxx.COM. + + * Change in the Ctrl+Y handling. The CtrlY handler now uses $delprc to + delete all children. This way also actions with DCL commands will be + stopped. As before the CtrlY handler then sends SIGQUIT to itself, + which is handled in common code. + + * Change in deleteing temporary command files. Temporary command files + are now deleted in the vms child termination handler. That deletes + them even if a Ctrl+C was pressed. + + * The behavior of pressing Ctrl+C is not changed. It still has only an + effect, after the current action is terminated.
