John Ericson ab822af0df Factor out serialization for BuildResult ... Worker Protocol: Note that the worker protocol already had a serialization for `BuildResult`; this was added in a4604f1928. It didn't have any versioning support because at that time reusable seralizers were not away for the protocol version. It could thus only be used for new messages also introduced in that commit. Now that we do support versioning in reusable serializers, we can expand it to support all known versions and use it in many more places. The exist test data becomes the version 1.29 tests: note that those files' contents are unchanged. 1.28 and 1.27 tests are added to cover the older code-paths. The keyered build result test only has 1.29 because the keying was also added in a4604f1928; the older serializations are always used unkeyed. Serve Protocol: Conversely, no attempt was made to factor out such a serializer for the serve protocol, so our work there in this commit for that protocol proceeds from scratch.		2023-10-20 15:19:28 -04:00
