Implement a simple allocation-free xx_hash utility class without using sun.misc.Unsafe. The hash function mainly targets on xDS use case, which is mostly small strings (endpoint address, headers, etc) and primitive types. In gRPC's use case, string characters need to be treated as ASCIIs to make the produced hash values match other implementations (Envoy, gRPC-Go, C-core, etc) would produce. The hashing implementation and tests are borrowed from OpenHFT's XxHash implementation (https://github.com/OpenHFT/Zero-Allocation-Hashing/blob/master/src/main/java/net/openhft/hashing/XxHash.java, see commit 658079a50903c32c54f2ab5c86243244b3ac60ed), which is under Apache 2.0 license. For more details, see https://github.com/OpenHFT/Zero-Allocation-Hashing. The code is made to be in third_party directory with LISENCE and NOTICE files. |
