566 * Otherwise we will merge all known log file types, and include the
567 * rotated logs for each type (you can suppress the inclusion of
568 * some logtypes through use of FMDUMP_AGGREGATE_IGNORE in the process
569 * environment, setting it to a comma-separated list of log labels and/or
570 * log filenames to ignore).
571 *
572 * We will not attempt to perform a chronological sort across all log records
573 * of all files. Indeed, we won't even sort individual log files -
574 * we will not re-order events differently to how they appeared in their
575 * original log file. This is because log files are already inherently
576 * ordered by the order in which fmd receives and processes events.
577 * So we determine the output order by comparing the "next" record
578 * off the top of each log file.
579 *
580 * We will construct a number of log record source "pipelines". As above,
581 * the next record to render in the overall output is that from the
582 * pipeline with the oldest event.
583 *
584 * For the case that input logfiles were listed on the command line, each
585 * pipeline will process exactly one of those logfiles. Distinct pipelines
586 * may process logfiles of the same "type" - eg if two "error" logs and
587 * one "fault" logs are specified then there'll be two pipelines producing
588 * events from "error" logs.
589 *
590 * If we are merging all known log types then we will construct exactly
591 * one pipeline for each known log type - one for error, one for fault, etc.
592 * Each pipeline will process first the rotated logs of that type and then
593 * move on to the current log of that type.
594 *
595 * The output from all pipelines flows into a serializer which selects
596 * the next record once all pipelines have asserted their output state.
597 * The output state of a pipeline is one of:
598 *
599 * - record available: the next record from this pipeline is available
600 * for comparison and consumption
601 *
602 * - done: this pipeline will produce no more records
603 *
604 * - polling: this pipeline is polling for new records and will
605 * make them available as output if/when any are observed
606 *
607 * - processing: output state will be updated shortly
608 *
609 * A pipeline iterates over each file queued to it using fmd_log_xiter.
610 * We do this in a separate thread for each pipeline. The callback on
611 * each iteration must update the serializer to let it know that
612 * a new record is available. In the serializer thread we decide whether
613 * we have all records expected have arrived and it is time to choose
614 * the next output record.
