* [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.
