This had to be added to SalesAgent constructor due to circular dependency issues, otherwise it would have been added directly to SalesAgent. - Sales: when an error during run is encountered, the SaleErrorState is constructed with the error, and by default (base impl) will return the error state, so the machine can transition to it. This can be overridden by individual states if needed. * [sales] rename onSaleFailed to onSaleErrored Because there is already a state named SaleFailed which is meant to react to an onchain RequestFailed event and also because this callback is called from SaleErrored, renaming to onSaleErrored prevents ambiguity and confusion as to what has happened at the callback callsite. * [statemachine] forward error to state directly without going through a machine method first * [statemachine] remove unnecessary error handling AsyncQueueFullError is already handled in schedule() * [statemachine] test that cancellation ignores onError * [sales] simplify error handling in states Rely on the state machine error handling instead of catching errors in the state run method --------- Co-authored-by: Mark Spanbroek <mark@spanbroek.net> * [statemachine] prevent memory leaks prevent memory leaks and nil access defects by: - allowing multiple subscribe/unsubscribes of salesagent - disallowing individual salesagent subscription calls to be made externally (requires the .subscribed check) - allowing mutiple start/stops of asyncstatemachine - disregard asyncstatemachine schedules if machine not yet started * [salesagent] add salesagent-specific tests 1. test multiple subscribe/unsubscribes 2. test scheduling machine without being started 3. test subscriptions are working correctly with external events 4. test errors can be overridden at the state level for ErrorHandlingStates. --------- Co-authored-by: Eric Mastro <eric.mastro@gmail.com> Co-authored-by: Mark Spanbroek <mark@spanbroek.net> Co-authored-by: Ben Bierens <thatbenbierens@gmail.com>

Slot queue (#455) ## Slot queue Adds a slot queue, as per the [slot queue design](https://github.com/codex-storage/codex-research/blob/master/design/sales.md#slot-queue). Any time storage is requested, all slots from that request are immediately added to the queue. Finished, Canclled, Failed requests remove all slots with that request id from the queue. SlotFreed events add a new slot to the queue and SlotFilled events remove the slot from the queue. This allows popping of a slot each time one is processed, making things much simpler. When an entire request of slots is added to the queue, the slot indices are shuffled randomly to hopefully prevent nodes that pick up the same storage requested event from clashing on the first processed slot index. This allowed removal of assigning a random slot index in the SalePreparing state and it also ensured that all SalesAgents will have a slot index assigned to them at the start thus the removal of the optional slotIndex. Remove slotId from SlotFreed event as it was not being used. RequestId and slotIndex were added to the SlotFreed event earlier and those are now being used The slot queue invariant that prioritises queue items added to the queue relies on a scoring mechanism to sort them based on the [sort order in the design document](https://github.com/codex-storage/codex-research/blob/master/design/sales.md#sort-order). When a storage request is handled by the sales module, a slot index was randomly assigned and then the slot was filled. Now, a random slot index is only assigned when adding an entire request to the slot queue. Additionally, the slot is checked that its state is `SlotState.Free` before continuing with the download process. SlotQueue should always ensure the underlying AsyncHeapQueue has one less than the maximum items, ensuring the SlotQueue can always have space to add an additional item regardless if it’s full or not. Constructing `SlotQueue.workers` in `SlotQueue.new` calls `newAsyncQueue` which causes side effects, so the construction call had to be moved to `SlotQueue.start`. Prevent loading request from contract (network request) if there is an existing item in queue for that request. Check availability before adding request to queue. Add ability to query market contract for past events. When new availabilities are added, the `onReservationAdded` callback is triggered in which past `StorageRequested` events are queried, and those slots are added to the queue (filtered by availability on `push` and filtered by state in `SalePreparing`). #### Request Workers Limit the concurrent requests being processed in the queue by using a limited pool of workers (default = 3). Workers are in a data structure of type `AsyncQueue[SlotQueueWorker]`. This allows us to await a `popFirst` for available workers inside of the main SlotQueue event loop Add an `onCleanUp` that stops the agents and removes them from the sales module agent list. `onCleanUp` is called from sales end states (eg ignored, cancelled, finished, failed, errored). Add a `doneProcessing` future to `SlotQueueWorker` to be completed in the `OnProcessSlot` callback. Each `doneProcessing` future created is cancelled and awaited in `SlotQueue.stop` (thanks to `TrackableFuturees`), which forced `stop` to become async. - Cancel dispatched workers and the `onProcessSlot` callbacks, prevents zombie callbacks #### Add TrackableFutures Allow tracking of futures in a module so they can be cancelled at a later time. Useful for asyncSpawned futures, but works for any future. ### Sales module The sales module needed to subscribe to request events to ensure that the request queue was managed correctly on each event. In the process of doing this, the sales agents were updated to avoid subscribing to events in each agent, and instead dispatch received events from the sales module to all created sales agents. This would prevent memory leaks on having too many eventemitters subscribed to. - prevent removal of agents from sales module while stopping, otherwise the agents seq len is modified while iterating An additional sales agent state was added, `SalePreparing`, that handles all state machine setup, such as retrieving the request and subscribing to events that were previously in the `SaleDownloading` state. Once agents have parked in an end state (eg ignored, cancelled, finished, failed, errored), they were not getting cleaned up and the sales module was keeping a handle on their reference. An `onCleanUp` callback was created to be called after the state machine enters an end state, which could prevent a memory leak if the number of requests coming in is high. Move the SalesAgent callback raises pragmas from the Sales module to the proc definition in SalesAgent. This avoids having to catch `Exception`. - remove unneeded error handling as pragmas were moved Move sales.subscriptions from an object containing named subscriptions to a `seq[Subscription]` directly on the sales object. Sales tests: shut down repo after sales stop, to fix SIGABRT in CI ### Add async Promise API - modelled after JavaScript Promise API - alternative to `asyncSpawn` that allows handling of async calls in a synchronous context (including access to the synchronous closure) with less additional procs to be declared - Write less code, catch errors that would otherwise defect in asyncspawn, and execute a callback after completion - Add cancellation callbacks to utils/then, ensuring cancellations are handled properly ## Dependencies - bump codex-contracts-eth to support slot queue (https://github.com/codex-storage/codex-contracts-eth/pull/61) - bump nim-ethers to 0.5.0 - Bump nim-json-rpc submodule to 0bf2bcb --------- Co-authored-by: Jaremy Creechley <creechley@gmail.com>

Cancel and wait for asyncstatemachine futures when stopping (#493) * Simplify `.then` (promise api) and tests * Remove tracked future when cancelled. Add tracked future tests * Track and cancel statemachine futures The futures created in each asyncstatemachine instance are tracked, and each future is cancelled and waited in `stop`. Change `asyncstatemachine.stop` to be async so `machine.trackedFutures.cancelAndWait` could be called. Add a constructor for `asyncstatemachine` that initialises the `trackedFutures` instance, and call the constructor from derived class constructors.
