| /** |
| * RocksDB is deprecating the RocksObject's finalizer that cleans up native |
| * resources. In fact, the finalizer is removed in the new version of RocksDB |
| * as per https://github.com/facebook/rocksdb/commit/99d86252b. That poses a |
| * requirement for RocksDb's applications to explicitly close RocksObject |
| * instances themselves to avoid leaking native resources. The general approach |
| * is to close RocksObjects with try-with-resource statement. |
| * Yet, this is not always an easy option in Ozone we need a mechanism to |
| * manage and detect leaks. |
| * |
| * This package contains wrappers and utilities to catch RocksObject |
| * instantiates in Ozone, intercept their finalizers and assert if the created |
| * instances are closed properly before being GCed. |
