@merlimat @hangc0276 Do we have any plans to update RocksDB version in Bookkeeper? We are currently on 7.9.2 and it seems that 7.10.2 is the newest 7.x: https://github.com/facebook/rocksdb/releases/tag/v7.10.2 . Newest release is 8.9.1: https://github.com/facebook/rocksdb/releases . |

Yet another crash, this time in broker tests. full dump https://gist.github.com/lhotari/f35745b737e7107f13c8becea80f9da4 |

@lhotari, thank you for your ongoing efforts in documenting this issue. Unfortunately, the CI artifact has expired: https://github.com/apache/pulsar/actions/runs/7299672614 In RocksDB, attempting to operate on a closed database instance leads to a crash. This behavior is documented in a related issue: facebook/rocksdb#5234 Below is a code snippet to demonstrate how to reproduce the crash: import org.junit.rules.TemporaryFolder;
import org.rocksdb.Options;
import org.rocksdb.RocksDB;
import org.rocksdb.RocksDBException;
import org.rocksdb.RocksIterator;
import java.io.IOException;
class Scratch {
static {
RocksDB.loadLibrary();
}
public static void main(String[] args) throws IOException, RocksDBException {
TemporaryFolder tempFolder = new TemporaryFolder();
tempFolder.create();
String path = tempFolder.newFolder().toString();
Options options = new Options();
options.setCreateIfMissing(true);
RocksDB db = RocksDB.open(options, path);
byte[] key = {0x1};
byte[] value = {0x2};
db.put(key, value);
RocksIterator it = db.newIterator();
db.close();
it.value(); // crashes the JVM
}
} |
@Shawyeok yes, that's most likely the case. It's probably an issue in the shutdown sequence in tests. The scheduled jobs that might access the db should be closed before the db. |
