Why make the change? As discussed previously, the way we will move across versions is to maintain completely separate codebases and eventually remove those that are not supported anymore. This has the drawback of some code duplication, but the advantage is that is more explicit what each version requires, and changes in one version will not impact the other, so we won't pile up backward compatible code. This is the same strategy used by `whisper` in go ethereum and is influenced by https://www.youtube.com/watch?v=oyLBGkS5ICk . All the code that is used for the networking protocol is now under `v0/`. Some of the common parts might still be refactored out. The main namespace `waku` deals with `host`->`waku` interactions (through RPC), while `v0` deals with `waku`->`remote-waku` interactions. In order to support `v1`, the namespace `v0` will be copied over, and changed to support `v1`. Once `v0` will be not used anymore, the whole namespace will be removed. This PR does not actually implement `v1`, I'd rather get things looked over to make sure the structure is what we would like before implementing the changes. What has changed? - Moved all code for the common parts under `waku/common/` namespace - Moved code used for bloomfilters in `waku/common/bloomfilter.go` - Removed all version specific code from `waku/common/const` (`ProtocolVersion`, status-codes etc) - Added interfaces for `WakuHost` and `Peer` under `waku/common/protocol.go` Things still to do Some tests in `waku/` are still testing by stubbing components of a particular version (`v0`). I started moving those tests to instead of stubbing using the actual component, which increases the testing surface. Some other tests that can't be easily ported should be likely moved under `v0` instead. Ideally no version specif code should be exported from a version namespace (for example the various codes, as those might change across versions). But this will be a work-in-progress. Some code that will be common in `v0`/`v1` could still be extract to avoid duplication, and duplicated only when implementations diverge across versions.
