crepererum opened a new issue #680:
URL: https://github.com/apache/arrow-datafusion/issues/680
**Describe the bug**
Catalog registered to `ExecutionContext` with an information schema are
never freed due to a cyclic Arc chain.
**To Reproduce**
Steps to reproduce the behavior:
```rust
#[tokio::test]
async fn catalogs_not_leaked() {
// the information schema used to introduce cyclic Arcs
let ctx = ExecutionContext::with_config(
ExecutionConfig::new().with_information_schema(true),
);
// register a single catalog
let catalog = Arc::new(MemoryCatalogProvider::new());
let catalog_weak = Arc::downgrade(&catalog);
ctx.register_catalog("my_catalog", catalog);
let catalog_list_weak = {
let state = ctx.state.lock().unwrap();
Arc::downgrade(&state.catalog_list)
};
drop(ctx);
assert_eq!(Weak::strong_count(&catalog_list_weak), 0);
assert_eq!(Weak::strong_count(&catalog_weak), 0);
}
```
**Expected behavior**
Memory is freed.
**Additional context**
Affects master branch at `58da15970dc0ec9e3c1c369fe89f6ba38e09d9c9`.
