In this PR, we're implementing the new SetConfig function on the LogEventProvider type. When called, the passed config struct is read, and the values are passed into the SetLimits function on the logEventBuffer type. The log buffer performs checks to ensure that if zero values are passed, we fall back to the default values for each config value.

Testing

The following tests were conducted through integration tests developed by @anirudhwarrier 🎉 🙏 🙌 ; the code samples are excerpts from a go codebase tasked with calling SetConfig on a deployed registry running against the code in this PR. The log samples are from grafana.

SetConfig with non-zero values in LogProviderConfig

LogProviderConfig: ocr2keepers30config.LogProviderConfig{
	NumOfLogUpkeeps:  10,
	FastExecLogsHigh: 5,
},

When SetConfig in the provider is called with non-zero values:

{"level":"info","ts":"2024-02-23T12:46:24.169Z","logger":"EVM.80001.Relayer.AutomationProvider.0fef745e-5507-4346-81da-2e742ad6af19.OCR2KeeperRelayer.KeepersRegistry.LogEventProvider","caller":"logprovider/provider.go:121","msg":"SetConfig called","version":"2.9.0@2023dfd","numOfLogUpkeeps":10,"fastExecLogsHigh":5}

SetLimits in the log buffer uses the off chain config values:

{"level":"info","ts":"2024-02-23T12:46:24.169Z","logger":"EVM.80001.Relayer.AutomationProvider.0fef745e-5507-4346-81da-2e742ad6af19.OCR2KeeperRelayer.KeepersRegistry.LogEventBuffer","caller":"logprovider/buffer.go:182","msg":"SetLimits called","version":"2.9.0@2023dfd","numOfLogUpkeeps":10,"fastExecLogsHigh":5}

SetConfig with missing LogProviderConfig

json.Marshal(ocr2keepers30config.OffchainConfig{
		TargetProbability:    a.PluginConfig.TargetProbability,
		TargetInRounds:       a.PluginConfig.TargetInRounds,
		PerformLockoutWindow: a.PluginConfig.PerformLockoutWindow,
		GasLimitPerReport:    a.PluginConfig.GasLimitPerReport,
		GasOverheadPerUpkeep: a.PluginConfig.GasOverheadPerUpkeep,
		MinConfirmations:     a.PluginConfig.MinConfirmations,
		MaxUpkeepBatchSize:   a.PluginConfig.MaxUpkeepBatchSize,
		//LogProviderConfig:    a.PluginConfig.LogProviderConfig,
	})

When SetConfig in the provider is called with zero values:

{"level":"info","ts":"2024-02-23T12:54:13.637Z","logger":"EVM.80001.Relayer.AutomationProvider.f7e3a0f8-005f-4de9-97ac-6ae477e52d65.OCR2KeeperRelayer.KeepersRegistry.LogEventProvider","caller":"logprovider/provider.go:121","msg":"SetConfig called","version":"2.9.0@2023dfd","numOfLogUpkeeps":0,"fastExecLogsHigh":0}

SetLimits in the log buffer uses the default values:

{"level":"info","ts":"2024-02-23T12:54:13.637Z","logger":"EVM.80001.Relayer.AutomationProvider.f7e3a0f8-005f-4de9-97ac-6ae477e52d65.OCR2KeeperRelayer.KeepersRegistry.LogEventBuffer","caller":"logprovider/buffer.go:182","msg":"SetLimits called","version":"2.9.0@2023dfd","numOfLogUpkeeps":50,"fastExecLogsHigh":32}
