2931e5dea8 C++: Reduce duplication by blocking flow into sources (since we'll already be considering flow starting at those sources) and out of sinks (since we'll already be alerting on this sink if it's relevant). 2023-03-09 14:59:13 +00:00

03ba7ea851 C++: Move the weird global property 'not sqlite_encryption_used()' from the sink definition to the source definition.
