The CircuitBreaker was introduced as means of preventing a `StackOverflowException` during the build of the AST by the parser. The ANTLR4 grammar causes a weird behaviour for a Parser Listener. The `enterEveryRule()` method is often called with a different parsing context than the respective `exitEveryRule()`. This makes it difficult to keep track of the tree's depth, and a custom Map was used as an attempt of matching the contextes as they are encounter during `enter` and during `exit` of the rules. This approach had 2 important drawbacks: 1. It's hard to maintain this custom Map as the grammar changes. 2. The CircuitBreaker could often lead to false positives which caused valid queries to return an Exception and prevent them from executing. So, this removes completely the CircuitBreaker which is replaced be a simple handling of the `StackOverflowException` Fixes: #41471 (cherry picked from commit 1559a8e2dbd729138b52e89b7e80264c9f4ad1e7) |
