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>

feat: create logging proxy (#663) * implement a logging proxy The logging proxy: - prevents the need to import chronicles (as well as export except toJson), - prevents the need to override `writeValue` or use or import nim-json-seralization elsewhere in the codebase, allowing for sole use of utils/json for de/serialization, - and handles json formatting correctly in chronicles json sinks * Rename logging -> logutils to avoid ambiguity with common names * clean up * add setProperty for JsonRecord, remove nim-json-serialization conflict * Allow specifying textlines and json format separately Not specifying a LogFormat will apply the formatting to both textlines and json sinks. Specifying a LogFormat will apply the formatting to only that sink. * remove unneeded usages of std/json We only need to import utils/json instead of std/json * move serialization from rest/json to utils/json so it can be shared * fix NoColors ambiguity Was causing unit tests to fail on Windows. * Remove nre usage to fix Windows error Windows was erroring with `could not load: pcre64.dll`. Instead of fixing that error, remove the pcre usage :) * Add logutils module doc * Shorten logutils.formatIt for `NBytes` Both json and textlines formatIt were not needed, and could be combined into one formatIt * remove debug integration test config debug output and logformat of json for integration test logs * Use ## module doc to support docgen * bump nim-poseidon2 to export fromBytes Before the changes in this branch, fromBytes was likely being resolved by nim-stew, or other dependency. With the changes in this branch, that dependency was removed and fromBytes could no longer be resolved. By exporting fromBytes from nim-poseidon, the correct resolution is now happening. * fixes to get compiling after rebasing master * Add support for Result types being logged using formatIt

Fix concurrency issues (#993) * Use http subscriptions instead of websocket for tests To work around this issue when subscriptions are inactive for more than 5 minutes: https://github.com/NomicFoundation/hardhat/issues/2053 Use 100 millisecond polling; default polling interval of 4 seconds is too close to the 5 second timeout for `check eventually`. * use .confirm(1) instead of confirm(0) confirm(0) doesn't wait at all, confirm(1) waits for the transaction to be mined * speed up partial payout integration test * update nim-ethers to version 0.10.0 includes fixes for http polling and .confirm() * fix timing of marketplace tests allow for a bit more time to withdraw funds * use .confirm(1) in marketplace tests to ensure that the transaction has been processed before continuing with the test * fix timing issue in validation unit test * fix proof integration test there were two logic errors in this test: - a slot is freed anyway at the end of the contract - when starting the request takes a long time, the first slot can already be freed because there were too many missing proofs * fix intermittent error in contract tests currentTime() doesn't always correctly reflect the time of the next transaction * reduce number of slots in integration test otherwise the windows runner in the CI won't be able to start the request before it expires * fix timing in purchasing test allow for a bit more time for a request to be submitted * fix timing of request submission in test windows ci is so slow, it can take up to 40 seconds just to submit a storage request to hardhat * increase proof period to 90 seconds * adjust timing of integration tests reason: with the increased period length of 90 seconds, it can take longer to wait for a stable challenge at the beginning of a period. * increase CI timeout to 2 hours * Fix slow builds on windows apparently it takes windows 2-3 seconds to resolve "localhost" to 127.0.0.1 for every json-rpc connection that we make 🤦

Fix concurrency issues (#993) * Use http subscriptions instead of websocket for tests To work around this issue when subscriptions are inactive for more than 5 minutes: https://github.com/NomicFoundation/hardhat/issues/2053 Use 100 millisecond polling; default polling interval of 4 seconds is too close to the 5 second timeout for `check eventually`. * use .confirm(1) instead of confirm(0) confirm(0) doesn't wait at all, confirm(1) waits for the transaction to be mined * speed up partial payout integration test * update nim-ethers to version 0.10.0 includes fixes for http polling and .confirm() * fix timing of marketplace tests allow for a bit more time to withdraw funds * use .confirm(1) in marketplace tests to ensure that the transaction has been processed before continuing with the test * fix timing issue in validation unit test * fix proof integration test there were two logic errors in this test: - a slot is freed anyway at the end of the contract - when starting the request takes a long time, the first slot can already be freed because there were too many missing proofs * fix intermittent error in contract tests currentTime() doesn't always correctly reflect the time of the next transaction * reduce number of slots in integration test otherwise the windows runner in the CI won't be able to start the request before it expires * fix timing in purchasing test allow for a bit more time for a request to be submitted * fix timing of request submission in test windows ci is so slow, it can take up to 40 seconds just to submit a storage request to hardhat * increase proof period to 90 seconds * adjust timing of integration tests reason: with the increased period length of 90 seconds, it can take longer to wait for a stable challenge at the beginning of a period. * increase CI timeout to 2 hours * Fix slow builds on windows apparently it takes windows 2-3 seconds to resolve "localhost" to 127.0.0.1 for every json-rpc connection that we make 🤦

This is to be replaced by a versioned library, so it will be pinned to a particular version. There is a crucial fix in this version of ethers that fixes nonce management which is causing issues in the Codex testnet. - nim-json-rpc to v0.4.4 - nim-json-serialization to v0.2.8 - nim-serde to v1.2.2 - nim-serialization to v0.2.4 Currently, one of the integration tests is failing. * fix integration test - When a state's run was cancelled, it was being caught as an error due to catching all CatchableErrors. This caused a state transition to SaleErrored, however cancellation of run was not actually an error. Handling this correctly fixed the issue. - Stopping of the clock was moved to after `HostInteractions` (sales) which avoided an assertion around getting time when the clock was not started. * bump ethers to include nonce fix and filter not found fix * bump ethers: fixes missing symbol not exported in ethers * Fix cirdl test imports/exports * Debugging in ci * Handle CancelledErrors for state.run in one place only * Rename `config` to `configuration` There was a symbol clash preventing compilation and it was easiest to rename `config` to `configuration` in the contracts. Not even remotely ideal, but it was the only way. * bump ethers to latest Prevents an issue were `JsonNode.items` symbol could not be found * More changes to support `config` > `configuration` * cleanup * testing to see if this fixes failure in ci * bumps contracts - ensures slot is free before allowing reservation - renames config to configuration to avoid symbol clash

There is no longer an overload in `Marketplace.sol` for `fillSlot` accepting no `payoutAddress`. * Update integration tests to include --payout-address * move payoutAddress from fillSlot to freeSlot * Update integration tests to use required payoutAddress - to make payoutAddress required, the integration tests needed to avoid building the cli params until just before starting the node, otherwise if cli params were added ad-hoc, there would be an error after a non-required parameter was added before a required parameter. * support client payout address - withdrawFunds requires a withdrawAddress parameter, directs payouts for withdrawing of client funds (for a cancelled request) to go to that address. * fix integration test adds --payout-address to validators * refactor: support withdrawFunds and freeSlot optional parameters - withdrawFunds has an optional parameter for withdrawRecipient - freeSlot has optional parameters for rewardRecipient and collateralRecipient - change --payout-address to --reward-recipient to match contract signature naming * Revert "Update integration tests to include --payout-address" This reverts commit 8f9535cf35b0f2b183ac4013a7ed11b246486964. There are some valid improvements to the integration tests, but they can be handled in a separate PR. * small fix * bump contracts to fix marketplace spec * bump codex-contracts-eth, now rebased on master * bump codex-contracts-eth now that feat/reward-address has been merged to master * clean up, comments

Fix concurrency issues (#993) * Use http subscriptions instead of websocket for tests To work around this issue when subscriptions are inactive for more than 5 minutes: https://github.com/NomicFoundation/hardhat/issues/2053 Use 100 millisecond polling; default polling interval of 4 seconds is too close to the 5 second timeout for `check eventually`. * use .confirm(1) instead of confirm(0) confirm(0) doesn't wait at all, confirm(1) waits for the transaction to be mined * speed up partial payout integration test * update nim-ethers to version 0.10.0 includes fixes for http polling and .confirm() * fix timing of marketplace tests allow for a bit more time to withdraw funds * use .confirm(1) in marketplace tests to ensure that the transaction has been processed before continuing with the test * fix timing issue in validation unit test * fix proof integration test there were two logic errors in this test: - a slot is freed anyway at the end of the contract - when starting the request takes a long time, the first slot can already be freed because there were too many missing proofs * fix intermittent error in contract tests currentTime() doesn't always correctly reflect the time of the next transaction * reduce number of slots in integration test otherwise the windows runner in the CI won't be able to start the request before it expires * fix timing in purchasing test allow for a bit more time for a request to be submitted * fix timing of request submission in test windows ci is so slow, it can take up to 40 seconds just to submit a storage request to hardhat * increase proof period to 90 seconds * adjust timing of integration tests reason: with the increased period length of 90 seconds, it can take longer to wait for a stable challenge at the beginning of a period. * increase CI timeout to 2 hours * Fix slow builds on windows apparently it takes windows 2-3 seconds to resolve "localhost" to 127.0.0.1 for every json-rpc connection that we make 🤦

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>

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>

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.

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>
