Parallel automake: ordered output messages. * lib/Automake/Channels.pm (%_default_options): New options `ordered' default enabled, `queue', default zero (no queue), `queue_key' default undefined. (_merge_options): Ensure `ordered' channels cannot have fatal messages or backtrace output. (_enqueue, _dequeue): New functions, to push messages onto a Thread::Queue, and output messages from such a queue, suitably weeded for duplicates in the same manner as _print_message. (_print_message): If the channel is ordered and has an associated queue, then enqueue messages instead of printing them. (setup_channel_queue, pop_channel_queue): New functions, to set a Thread::Queue for channels, and to flush a queue. * lib/Automake/ChannelDefs.pm: Unset channel option `ordered' for fatal, automake, and verb channels. * automake.in (QUEUE_MESSAGE): New global constant, used as serialization key. (handle_makefiles_threaded): Create message queues for each input file; workers queue messages, and the master outputs them ordered, using the new Channels.pm functions. * tests/parallel-am.test: Also check for ordered output (in the absence of --add-missing races). * tests/parallel-am2.test: New test; check for ordered output of warning and (regular) error messages. * tests/Makefile.am: Adjust.
