Changes in version 0.7.0 - Overhaul worker configuration and creation; now all worker configuration options (except redis and storage control) are set through a named worker configuration; this reduces the number of arguments being passed around and improves documentation (mrc-4068) Changes in version 0.6.16 - Extend fault tolerance support by enabling tasks to be retried; this creates a new task that the old task points at and can be used to seamlessly recover from all sorts of task failure (mrc-2683) - Queues print vertically when printing out worker info (mrc-4114) Changes in version 0.6.14 - New $task_info method to retrieve more detailed information about where a task was run (mrc-4058) Changes in version 0.6.13 - Argument standardisation for timeouts, with changes: - collect_timeout in bulk functions becomes timeout_task_wait - worker_stop_timeout in the rrq_controller's destroy method becomes timeout_worker_stop - task_timeout in queuing a task on a separate process, in bulk submission functions becomes timeout_task_run - timeout in enqueue becomes timeout_task_run Changes in version 0.6.12 - New argument timeout_task_wait and option rrq.timeout_task_wait to control the default time to wait for tasks to be returned from task_wait and bulk task retrieval methods. The default behaviour is unchanged (blocking indefinitely) but this can now easily be changed at a global or queue-scoped level. Changes in version 0.6.11 - Changed argument of worker_config_save from timeout to timeout_idle (mrc-4075) Changes in version 0.6.10 - It is now possible to (optionally) throw task errors on retrieval via task_wait, task_results and the bulk interfaces. The default remains not to error. - Bulk submitted tasks no longer auto-delete. Changes in version 0.6.7 - Nicer errors that tell you what the contain, particularly when they have stack traces or warnings (mrc-1260) Changes in version 0.6.6 - Drop at_front argument (introduced in rrq 0.2.14), tasks can no longer jump the queue (mrc-4069) Changes in version 0.6.5 - Error traces now come from rlang and are much nicer to read (mrc-4060) Changes in version 0.6.4 - Make separate process timeouts timeout_poll and timeout_die configurable via the worker config. Changes in version 0.6.1 - Simplify version information returned by worker_info (mrc-2295) Changes in version 0.6.0 - Renamed some functions with rrq_ prefix; you must now use rrq_worker_spawn() (not worker_spawn), rrq_worker_wait, rrq_heartbeat and rrq_heartbeat_kill (mrc-2682) Changes in version 0.4.1 - Expose rrq::rrq_worker_from_config, which is a simpler way of constructing worker objects. The worker object itself (rrq::rrq_worker) loses its helper constructor function and is documented (mrc-2297) Changes in version 0.3.2 - All tasks get a key that can be checked with a blocking wait (mrc-2392) Changes in version 0.3.1 - Direct control over environment export for $enqueue() with new argument export (mrc-2369) Changes in version 0.2.19 - Add new enqueue_bulk method (previously deleted in 0.2.0) (mrc-2261) Changes in version 0.2.15 - enqueue can add a task with dependencies i.e. tasks which must be complete before this task can be run via depends_on (mrc-2255) Changes in version 0.2.14 - enqueue can add a task to start of the queue via at_front = TRUE (mrc-2254) Changes in version 0.2.13 - Run tasks in a separate process (with some overhead) with new argument separate_process = TRUE to $enqueue(). Use this to ensure isolation between tasks (mrc-2068) Changes in version 0.2.12 - Add task_preceeding function to controller to list tasks in front of a particular task in the queue (vimc-4502) Changes in version 0.2.11 - Support for multiple queues, with varying priorities. This can be used to create workers that listen to overlapping queues, with "fast" and "slow" queues (mrc-2068) Changes in version 0.2.10 - Gracefully detect multiple killed workers (#22, reported by @MartinHanewald) Changes in version 0.2.9 - $lapply and friends restored after being removed during the refactor for version 0.2.0 (mrc-558) Changes in version 0.2.8 - Expand documentation (mrc-1800) Changes in version 0.2.7 - rrq progress now passes all fields in underlying condition (mrc-1772) Changes in version 0.2.6 - Update worker_spawn to work with breaking change in docopt (mrc-1667) Changes in version 0.2.5 - New $task_data method for getting underlying task data (mrc-1304) Changes in version 0.2.4 - Better error message is given when non-existent task is cancelled (mrc-1259) Changes in version 0.2.3 - New $worker_detect_exited for detecting exited workers when a heartbeat is used (mrc-1231) Changes in version 0.2.2 - Tasks can now be interrupted with $task_cancel if running with a heartbeat enabled (mrc-734) Changes in version 0.2.1 - Add support for within-task progress updates, using the rrq::rrq_task_progress_update function, which can be called from any task run from rrq and queried with $task_progress from a rrq_controller (mrc-600) Changes in version 0.2.0 - Rewrite of the package to simplify queue creation and dependency chain (mrc-538 / #9, mrc-519 / #8, mrc-472 / #7)
