YAS-335 Improvements to Ethereum event endpoints by ben-chain · Pull Request #116 · ethereum-optimism/optimism

ben-chain · 2020-04-28T20:25:14Z

Description

Fixes YAS-335 improvements around event logging, particularly:

fixing and testing that multi-contract-event transaction logs are parsed correctly
fixing bug where contracts could emit events that looked like execution manager events and trick the handler into parsing false events on other contracts' behalf
fixing logIndex (not well tested but appears to work -- wasn't breaking anything anyway)

Questions

Caveats with the current setup:

At this time, we add the execution manager address to any filtering, which could end up consuming lots of resources unnecessarily.
At this time, we do not correctly parse events emitted with DELEGATECALL -- they will appear to be emitted by the callee's OVM address instead of the caller's OVM address.
Filtering by topic is not supported, though is likely high priority in terms of getting eth_getLogs up to par for Dev Ex. Appears not to be needed for the Graph, so creating a separate ticket for it.

packages/ovm/src/app/utils.ts

-        activeContract = executionManagerLog.values['_activeContract']
+    if (log.address.toUpperCase() === executionManagerAddress.toUpperCase()) {
+      const EMLogIndex = log.logIndex
+      if (EMLogIndex < prevEMLogIndex) {


should tihs be <=? E.g. if prevEMlogIndex is 0, and EMLogIndex is 0, it's still a new transaction, right?

nice catch!

-      ovmLogs.push({ ...log, address: activeContract })
+      const newIndex = log.logIndex - cumulativeTxEMLogIndices

LMAO so glad you caught it

Could you add one more test here that filters by topic "taco", and makes sure that only 1 log is returned, and it's the right one?

K-Ho

Looks great!!! just 1 more test suggestion, and that one ">=" note

packages/ovm/src/app/abi.ts

+/* External Imports */
+import { utils, ContractFactory } from 'ethers'
+
+/* Internal Imports */
+import * as ExecutionManager from '../../build/contracts/ExecutionManager.json'
+
+const EMContract = new ContractFactory(
+  ExecutionManager.abi,
+  ExecutionManager.bytecode
+)
+const EMEvents = EMContract.interface.events
+const topics = []
+for (const eventKey of Object.keys(EMEvents)) {
+  topics.push(EMEvents[eventKey].topic)
+}
+
+export const ALL_EXECUTION_MANAGER_EVENT_TOPICS = topics


could this go in utils.ts? It has and exports abi stuff. If nothing else, maybe reference it instead of importing the contract?

Happy to move to utils, but what do you mean by "reference instead of import"?

Just to export from here and reference. Not a big priority though.

packages/ovm/src/app/utils.ts

+      const executionManagerLog = executionManagerInterface.parseLog(log)
+      if (!executionManagerLog) {
+        loggerLogs.push(
+          `execution manager log ${log} was unrecognized by the interface parser--Definitely not an activeContract event, ignoring...`


I think ${log} will just print [object Object], but JSON.stringify(...) will result in circular error. Is there another property that would be useful to log here? log.name?

Should you log ${JSON.stringify(filter)}? It's probably just going to print [object Object] otherwise.
