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

[marketplace] Availability improvements (#535)
## Problem
When Availabilities are created, the amount of bytes in the Availability are reserved in the repo, so those bytes on disk cannot be written to otherwise. When a request for storage is received by a node, if a previously created Availability is matched, an attempt will be made to fill a slot in the request (more accurately, the request's slots are added to the SlotQueue, and eventually those slots will be processed). During download, bytes that were reserved for the Availability were released (as they were written to disk). To prevent more bytes from being released than were reserved in the Availability, the Availability was marked as used during the download, so that no other requests would match the Availability, and therefore no new downloads (and byte releases) would begin. The unfortunate downside to this, is that the number of Availabilities a node has determines the download concurrency capacity. If, for example, a node creates a single Availability that covers all available disk space the operator is willing to use, that single Availability would mean that only one download could occur at a time, meaning the node could potentially miss out on storage opportunities.

## Solution
To alleviate the concurrency issue, each time a slot is processed, a Reservation is created, which takes size (aka reserved bytes) away from the Availability and stores them in the Reservation object. This can be done as many times as needed as long as there are enough bytes remaining in the Availability. Therefore, concurrent downloads are no longer limited by the number of Availabilities. Instead, they would more likely be limited to the SlotQueue's `maxWorkers`.

From a database design perspective, an Availability has zero or more Reservations.

Reservations are persisted in the RepoStore's metadata, along with Availabilities. The metadata store key path for Reservations is ` meta / sales / reservations / <availabilityId> / <reservationId>`, while Availabilities are stored one level up, eg `meta / sales / reservations / <availabilityId> `, allowing all Reservations for an Availability to be queried (this is not currently needed, but may be useful when work to restore Availability size is implemented, more on this later).

### Lifecycle
When a reservation is created, its size is deducted from the Availability, and when a reservation is deleted, any remaining size (bytes not written to disk) is returned to the Availability. If the request finishes, is cancelled (expired), or an error occurs, the Reservation is deleted (and any undownloaded bytes returned to the Availability). In addition, when the Sales module starts, any Reservations that are not actively being used in a filled slot, are deleted.

Having a Reservation persisted until after a storage request is completed, will allow for the originally set Availability size to be reclaimed once a request contract has been completed. This is a feature that is yet to be implemented, however the work in this PR is a step in the direction towards enabling this.

### Unknowns
Reservation size is determined by the `StorageAsk.slotSize`. If during download, more bytes than `slotSize` are attempted to be downloaded than this, then the Reservation update will fail, and the state machine will move to a `SaleErrored` state, deleting the Reservation. This will likely prevent the slot from being filled.

### Notes
Based on #514

Improve integration testing client (CodexClient) and json serialization (#514)
* Improve integration testing client (CodexClient) and json serialization

The current client used for integration testing against the REST endpoints for Codex accepts and passes primitive types. This caused a hard to diagnose bug where a `uint` was not being deserialized correctly.

In addition, the json de/serializing done between the CodexClient and REST client was not easy to read and was not tested.

These changes bring non-primitive types to most of the CodexClient functions, allowing us to lean on the compiler to ensure we're providing correct typings. More importantly, a json de/serialization util was created as a drop-in replacement for the std/json lib, with the main two differences being that field serialization is opt-in (instead of opt-out as in the case of json_serialization) and serialization errors are captured and logged, making debugging serialization issues much easier.

* Update integration test to use nodes=2 and tolerance=1

* clean up

[repostore] Retrieve empty blocks (#513)
Add handling of empty blocks in the RepoStore.

* Add empty block handling to repostore for put, del, has
Also added tests for all empty block handling blockstore operations. This showed there was an ambiguous identifier present for `hasBlock`, so one of the two `hasBlock` definitions was removed in `repostore`.

* Change CacheStore to RepoStore in testerasure
As CacheStore is not used in the node, update the Datastore used in the erasure coding tests to be a RepoStore. This ensures that the K > 1 cases are being tested, where they will produce empty padding blocks in the erasure-coded manifests.

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.

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

[marketplace] Add Reservations Module (#340)
* [marketplace] reservations module

- add de/serialization for Availability
- add markUsed/markUnused in persisted availability
- add query for unused
- add reserve/release
- reservation module tests
- split ContractInteractions into client contracts and host contracts
- remove reservations start/stop as the repo start/stop is being managed by the node
- remove dedicated reservations metadata store and use the metadata store from the repo instead
- Split ContractInteractions into:
  - ClientInteractions (with purchasing)
  - HostInteractions (with sales and proving)
- compilation fix for nim 1.2

[repostore] fix started flag, add tests

[marketplace] persist slot index
For loading the sales state from chain, the slot index was not previously persisted in the contract. Will retrieve the slot index from the contract when the sales state is loaded.

* Revert repostore changes

In favour of separate PR https://github.com/status-im/nim-codex/pull/374.

* remove warnings

* clean up

* tests: stop repostore during teardown

* change constructor type identifier

Change Contracts constructor to accept Contracts type instead of ContractInteractions.

* change constructor return type to Result instead of Option

* fix and split interactions tests

* clean up, fix tests

* find availability by slot id

* remove duplication in host/client interactions

* add test for finding availability by slotId

* log instead of raiseAssert when failed to mark availability as unused

* move to SaleErrored state instead of raiseAssert

* remove unneeded reverse

It appears that order is not preserved in the repostore, so reversing does not have the intended effect here.

* update open api spec for potential rest endpoint errors

* move functions about available bytes to repostore

* WIP: reserve and release availabilities as needed

WIP: not tested yet

Availabilities are marked as used when matched (just before downloading starts) so that future matching logic does not match an availability currently in use.

As the download progresses, batches of blocks are written to disk, and the equivalent bytes are released from the reservation module. The size of the availability is reduced as well.

During a reserve or release operation, availability updates occur after the repo is manipulated. If the availability update operation fails, the reserve or release is rolled back to maintain correct accounting of bytes.

Finally, once download completes, or if an error occurs, the availability is marked as unused so future matching can occur.

* delete availability when all bytes released

* fix tests + cleanup

* remove availability from SalesContext callbacks

Availability is no longer used past the SaleDownloading state in the state machine. Cleanup of Availability (marking unused) is handled directly in the SaleDownloading state, and no longer in SaleErrored or SaleFinished. Likewise, Availabilities shouldn’t need to be handled on node restart.

Additionally, Availability was being passed in SalesContext callbacks, and now that Availability is only used temporarily in the SaleDownloading state, Availability is contextually irrelevant to the callbacks, except in OnStore possibly, though it was not being consumed.

* test clean up

* - remove availability from callbacks and constructors from previous commit that needed to be removed (oopsie)
- fix integration test that checks availabilities
  - there was a bug fixed that crashed the node due to a missing `return success` in onStore
  - the test was fixed by ensuring that availabilities are remaining on the node, and the size has been reduced
- change Availability back to non-ref object and constructor back to init
- add trace logging of all state transitions in state machine
- add generally useful trace logging

* fixes after rebase

1. Fix onProve callbacks
2. Use Slot type instead of tuple for retrieving active slot.
3. Bump codex-contracts-eth that exposes getActivceSlot call.

* swap contracts branch to not support slot collateral

Slot collateral changes in the contracts require further changes in the client code, so we’ll skip those changes for now and add in a separate commit.

* modify Interactions and Deployment constructors

- `HostInteractions` and `ClientInteractions` constructors were simplified to take a contract address and no overloads
- `Interactions` prepared simplified so there are no overloads
- `Deployment` constructor updated so that it takes an optional string parameter, instead `Option[string]`

* Move `batchProc` declaration

`batchProc` needs to be consumed by both `node` and `salescontext`, and they can’t reference each other as it creates a circular dependency.

* [reservations] rename `available` to `hasAvailable`

* [reservations] default error message to inner error msg

* add SaleIngored state

When a storage request is handled but the request does match availabilities, the sales agent machine is sent to the SaleIgnored state. In addition, the agent is constructed in a way that if the request is ignored, the sales agent is removed from the list of active agents being tracked in the sales module.

* [sales] move asyncSpawn helper to utils

* [sales] fix imports

* [sales] remove unused variables

* [sales statemachine] add async state machine error handling (#349)

* [statemachine] add error handling to asyncstatemachine

- add error handling to catch errors during state.run
- Sales: add ErrorState to identify which state to transition to during an error. 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

* [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.

Speed up development (#303)
* [ci] Extract setup of nimbus build system into separate file

* [ci] Cleanup NodeJS setup

* [ci] Use amd64 by default

* [ci] Separate steps for unit, contract and integration tests

* [ci] Separate build job for coverage that is allowed to fail

* [ci] Separate build job for Nim 1.2

* [ci] Calculate coverage on unit tests only

This enables faster development cycles at
the expense of code coverage accuracy.

* [PoR] Test proofs of retrievability with a small block size

To get a reasonable test execution time.

* [ci] Set NIM_COMMIT environment variable

To prevent subsequent `make` command to build a
different version of Nim.

* [ci] Checkout submodules recursively

So that nimbus-build-system doesn't have to
do it afterwards.

* [ci] Update caches on every run

Will automatically update caches when a new minor version
of Nim is released.

See also:
https://github.com/actions/cache/blob/main/workarounds.md#update-a-cache

* [ci] Set cache_nonce for all jobs, not just those in the matrix

* [build] update to latest nimbus-build-system

Requires an update to latest nim-nat-traversal

* [erasure] Test erasure coding with a small block size

To get a reasonable test execution time.

* [erasure] fix typo

* [PoR] Test PoR store with a small block size

To get a reasonable test execution time.

* [PoR] Test PoR network with a small block size

To get a reasonable test execution time.

* [ci] Ensure that unit tests are not dependent on Ethereum

Start Ethereum node *after* the unit tests are run.

* [ci] Cancel all other jobs when one fails

Allows for faster feedback loops; a next attempt to run
the CI will start sooner.

Load purchase state from chain (#283)
* [purchasing] Simplify test

* [utils] Move StorageRequest.example up one level

* [purchasing] Load purchases from market

* [purchasing] load purchase states

* Implement myRequest() and getState() methods for OnChainMarket

* [proofs] Fix intermittently failing tests

Ensures that examples of proofs in tests are never of length 0;
these are considered invalid proofs by the smart contract logic.

* [contracts] Fix failing test

With the new solidity contracts update, a contract can only
be paid out after it started.

* [market] Add method to get request end time

* [purchasing] wait until purchase is finished

Purchase.wait() would previously wait until purchase
was started, now we wait until it is finished.

* [purchasing] Handle 'finished' and 'failed' states

* [marketplace] move to failed state once request fails

- Add support for subscribing to request failure events.
- Add supporting contract tests for subscribing to request failure events.
- Allow the PurchaseStarted state to move to PurchaseFailure once a request failure event is emitted
- Add supporting tests for moving from PurchaseStarted to PurchaseFailure
- Add state transition tests for PurchaseUnknown.

* [marketplace] Fix test with longer sleepAsync

* [integration] Add function to restart a codex node

* [purchasing] Set client address before requesting storage

To prevent the purchase id (which equals the request id)
from changing once it's been submitted.

* [contracts] Fix: OnChainMarket.getState()

Had the wrong method signature before

* [purchasing] Load purchases on node start

* [purchasing] Rename state 'PurchaseError' to 'PurchaseErrored'

Allows for an exception type called 'PurchaseError'

* [purchasing] Load purchases in background

No longer calls market.getRequest() for every purchase
on node start.

* [contracts] Add `$` for RequestId, SlotId and Nonce

To aid with debugging

* [purchasing] Add Purchasing.stop()

To ensure that all contract interactions have both a
start() and a stop() for

* [tests] Remove sleepAsync where possible

Use `eventually` loop instead, to make sure that we're
not waiting unnecessarily.

* [integration] Fix: handle non-json response in test

* [purchasing] Add purchase state to json

* [integration] Ensure that purchase is submitted before restart

Fixes test failure on slower CI

* [purchasing] re-implement `description` as method

Allows description to be set in the same module where the
state type is defined.

Remove `isSlotCancelled` and `isCancelled` from proving, as it did not fit in the module.

Update the proving module to not rely on checking the contract to understand if a request was cancelled. Instead, `proofEnd` was modified in `dagger-contracts` such that it returns a past timestamp when the contract is cancelled. This successfully removes

Eric Mastro 372f827982 [marketplace] add/remove proofs for contract state
Add or remove proof requirements when a request contract’s state changes. When a request sale has completed (for a slot), the host who purchased that slot now must provide regular proofs for the data they are contracted to hold. This is now enforced by adding the slotId to the HashSet of Ids for which to require proofs. When a request has been cancelled (not all slots were filled before the request expired), proofs no longer need to be provided and the slotId is removed from teh HashSet.

Add `isCancelled` and `isSlotCancelled` checks to query the contract state without relying the on the state context variable in the contract. Because contract state can only be updated in a transaction, and the client withdrawing funds is responsible for changing the contract state to “Cancelled”, the `isCancelled` and `isSlotCancelled` functions were introduced to check the state regardless of whether or not the client had already withdrawn their funds.

Eric Mastro 0c3fbad470 [purchasing] Withdraw funds when request times out
When a request for storage times out (not enough slots filled), the client will initiate a withdraw request to retrieve its funds out of the contract, setting the state of the request to RequestState.Cancelled. The client will also emit a RequestCancelled event for others to listen to (ie hosts will need to listen for this event to withdraw its collateral).

Add unit test that checks for emission of RequestCancelled after request is purchased request expires.

Update dagger-contracts dependency to commit that holds the changes supporting withdrawing of funds.

Download files without padding (#218)
The initial goal of this patch was to allow to download of a file via REST API in exactly the same size as it was uploaded, which required adding fields Chunker.offset and Manifest.originalBytes to keep that size. On top of that, we added more integrity checks to operations on Manifest, and reorganized TestNode.nim to test the actual interaction between node.store and node.retrieve operations.

Note that the wire format of Manifest was changed, so we need to recreate all BlockStores.

* Download without padding
* Fixed chunker tests
* Chunker: get rid of RabinChunker
* Verify offset in the chunker tests
* Use manifest.originalBytesPadded in StoreStream.size
* StoreStream: replace emptyBlock with zeroMem
* Manifest.bytes: compute how many bytes corresponding StoreStream(Manifest, pad) will return
* Manifest: verify originalBytes and originalLen on new/encode/decode
Also set originalBytes in each Manifest creation/update scenario
* Manifest: comments, split code into sections
* Reordered parameters to deal with int64 size in 32-bit builds
* TestNode.nim: combine Store and Retrieve tests
1. Instead of copy-pasting code from node.nim, new test calls node.store() and node.retrieve() in order to check that they can correctly store and then retrieve data
2. New test compares only file contents, manifest contents considered an implementation detail
3. New test chunks at odd chunkSize=BlockSize/1.618 in order to ensure that data retrieved correctly even when buffer sizes mismatch
* TestNode.nim: code refactoring
* Manifest.add: one more test
* Manifest.verify: return Result instead of raising Defect
* Node.store: added blockSize parameter
