* [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.

* [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.

* [contracts] fix typo

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
- rename `ContractId` to `SlotId`
- rename `Proving.contracts` to `Proving.slots`
- change signatures of `isSlotCancelled` and `isCancelled` to use `SlotId` and `RequestId` types, respectively.
- change all references to `RequestId`, `SlotId`
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.
- rename `ContractId` to `SlotId`
- add `RequestId`, `PurchaseId`, `Nonce` types as aliases of `array[32, byte]`
- rename `Proving.contracts` to `Proving.slots`
- change signatures of `isSlotCancelled` and `isCancelled` to use `SlotId` and `RequestId` types, respectively.
- change all references to `RequestId`, `SlotId`, and `PurchaseId`
* Add Proving object, which maintains contract id's to watch
* [proving] invoke callback when proof is required
# Conflicts:
# dagger/por/timing/periods.nim
# dagger/por/timing/prooftiming.nim
* [proving] check proof requirements for all our contracts
# Conflicts:
# tests/dagger/helpers/mockprooftiming.nim
* Update vendor/dagger-contracts
* [proving] call onProofRequired() when proof is required soon
* [proving] stop checking contracts that have ended
* [proving] Remove duplicated funcs
* [proving] Implement ProofTiming on top of smart contract
* [proving] Fix race condition in waitUntilNextPeriod()
Sometimes waitUntilNextPeriod would take a while to
determine the current period, leading to unexpected results.
Splits waitUntilNextPeriod() into getCurrentPeriod()
and waitUntilPeriod(), to ensure that we're really waiting
for the period that we think we're waiting for.
Integrate dagger contracts from `nim-dagger-contracts` repo.
Add `dagger-contracts`, `nim-web3`, and all of `nim-web3`’s transitive deps as submodule deps to `nim-dagger`. Note: `nim-web3` and its transitive deps may no longer be needed when we switch to `nim-ethers`.
Add a `testContracts` nimble task to test all of the contracts functionality. Namely, this spins up an ethereum simulator, deploys the contracts (in `dagger-contracts`), runs the contract tests, and finally, regardless of success/error, kills the ethereum sim processes. The nimble task can be run with `./env.sh nimble testContracts`.
We also tested `nim-dagger-contracts` as a submodule dep of `nim-dagger`, and while the tests run as expected, the preference is to merge `nim-dagger-contracts` inside of `nim-dagger` for ease of parallel development. There’s also a high probability that `nim-dagger-contracts` is not being used as a dep by other projects. Are there any strong objections to this?
