- rename `SalesAgent.init` to `start` and `SalesAgent.deinit` to `stop`.
- rename `SalesAgent. populateRequest` to `SalesAgent.retreiveRequest`.
- move availability removal to the downloading state. once availability is persisted to disk, it should survive node restarts.

* [marketplace] handle slot filled by other host

Handle the case when in the downloading, proving, or filling states, that another host fills the slot.

- getState / state > requestState
- getSlot > getRequestFromSlotId
- support MarketplaceConfig

* [statemachine] add machine parameter to run method

* [statemachine] initialize queue on start

* [statemachine] check futures before cancelling them

* [sales] use new async state machine

- states use new run() method and event mechanism
- StartState starts subscriptions and loads request

* [statemachine] fix unsusbscribe before subscribe

* [sales] replace old state transition tests

* [sales] separate state machine from sales data

* [sales] remove reference from SalesData to Sales

* [sales] separate sales context from sales

* [sales] move decoupled types into their own modules

* [sales] move retrieveRequest to SalesData

* [sales] move subscription logic into SalesAgent

* [build] revert back to released version of nim-ethers

* [sales] remove SaleStart state

* [sales] add missing base method

* [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.

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.

* [market] Use more generic error type

Should we decide to change the provider type later

Eric Mastro 25df599c08 Update to new reverts API, add tests
1. use `ProviderError` to catch contract errors instaed of `JsonRpcProviderError`.
2. Add tests for `isProofRequired`, `willProofBeRequired`, and `getProofEnd` when slot is empty (and is call is reverted)
3. bump nim-ethers to branch that has new `reverts` API and `ProviderError` support.
4. Update to new `reverts` API.

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.
