Smith <psmith@gnu.org> + + * remake.c (update_file): Move the considered check into the + double-colon rule loop, so we consider double-colon rules + individually (otherwise after the first is pruned, the rest might + not get run). + + * README.template: Minor changes. + + Remove the debugging features of the jobserver, so it no longer + writes distinct tokens to the pipe. Thus, we don't need to store + the token we get. A side effect of this is to remove a potential + "unavailable token" situation: make-1 invokes make-2 with its + special token and make-3 with a normal token; make-2 completes. + Now we're waiting for make-3 but using 2 tokens; our special token + is idle. In the new version we don't have special tokens per se, + we merely decide if we already have a child or not. If we don't, + we don't need a token. If we do, we have to get one to run the + next child. Similar for putting tokens back: if we're cleaning up + the last child, we don't put a token back. Otherwise, we do. + + * main.c: Add a new, internal flag --jobserver-fds instead of + overloading the meaning of -j. Remove job_slots_str and add the + stringlist jobserver_fds. + (struct command_switch): We don't need the int_string type. + (switches[]): Add a new option for --jobserver-fds and remove + conditions around -j. Make the description for the former 0 so it + doesn't print during "make --help". + (main): Rework jobserver parsing. If we got --jobserver-fds + make sure it's valid. We only get one and job_slots must be 0. + If we're the toplevel make (-jN without --jobserver-fds) create + the pipe and write generic tokens. + Create the stringlist struct for the submakes. + Clean up the stringlist where necessary. + (init_switches): Remove int_string handling. + (print_usage): Don't print internal flags (description ptr is 0). + (decode_switches): Remove int_string handling. + (define_makeflags): Remove int_string handling. + + * job.c: Remove my_job_token flag and all references to the + child->job_token field. + (free_job_token): Remove this and merge it into free_child(). + (reap_children): Rework the "reaped a child" logic slightly. + Don't call defunct free_job_token anymore. Always call + free_child, even if we're dying. + (free_child): If we're not freeing the only child, put a token + back in the pipe. Then, if we're dying, don't bother to free. + (new_job): If we are using the jobserver, loop checking to see if + a) there are no children or b) we get a token from the pipe. + + * job.h (struct child): Remove the job_token field. + 1999-08-20 Paul D. Smith <psmith@gnu.org> * variable.c (try_variable_definition): Allocate for variable |
