rrq 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)

rrq 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)

rrq 0.6.14

• New $task_info method to retrieve more detailed information about where a task was run (mrc-4058)

rrq 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

rrq 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.

rrq 0.6.11

• Changed argument of worker_config_save from timeout to timeout_idle (mrc-4075)

rrq 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.

rrq 0.6.7

• Nicer errors that tell you what the contain, particularly when they have stack traces or warnings (mrc-1260)

rrq 0.6.6

• Drop at_front argument (introduced in rrq 0.2.14), tasks can no longer jump the queue (mrc-4069)

rrq 0.6.5

• Error traces now come from rlang and are much nicer to read (mrc-4060)

rrq 0.6.4

• Make separate process timeouts timeout_poll and timeout_die configurable via the worker config.

rrq 0.6.1

• Simplify version information returned by worker_info (mrc-2295)

rrq 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)

rrq 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)

rrq 0.3.2

• All tasks get a key that can be checked with a blocking wait (mrc-2392)

rrq 0.3.1

• Direct control over environment export for $enqueue() with new argument export (mrc-2369)

rrq 0.2.19

• Add new enqueue_bulk method (previously deleted in 0.2.0) (mrc-2261)

rrq 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)

rrq 0.2.14

• enqueue can add a task to start of the queue via at_front = TRUE (mrc-2254)

rrq 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)

rrq 0.2.12

• Add task_preceeding function to controller to list tasks in front of a particular task in the queue (vimc-4502)

rrq 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)

rrq 0.2.10

• Gracefully detect multiple killed workers (#22, reported by @MartinHanewald)

rrq 0.2.9

• $lapply and friends restored after being removed during the refactor for version 0.2.0 (mrc-558)

rrq 0.2.8

• Expand documentation (mrc-1800)

rrq 0.2.7

• rrq progress now passes all fields in underlying condition (mrc-1772)

rrq 0.2.6

• Update worker_spawn to work with breaking change in docopt (mrc-1667)

rrq 0.2.5

• New $task_data method for getting underlying task data (mrc-1304)

rrq 0.2.4

• Better error message is given when non-existent task is cancelled (mrc-1259)

rrq 0.2.3

• New $worker_detect_exited for detecting exited workers when a heartbeat is used (mrc-1231)

rrq 0.2.2

• Tasks can now be interrupted with $task_cancel if running with a heartbeat enabled (mrc-734)

rrq 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)

rrq 0.2.0

• Rewrite of the package to simplify queue creation and dependency chain (mrc-538 / #9, mrc-519 / #8, mrc-472 / #7)
