Go upgrade:
- Go 1.23 is current => use that for release builds
- Go 1.22 is less than one year old, it's desirable to support it.
- The [`Go Toolchains`](https://go.dev/doc/toolchain) stuff is available
in both of these (would also be in Go 1.21). That is quite nice stuff,
but required some changes to how we versions we use in CircleCI and
the `release-docker` Makefile target.
Protobuf upgrade:
- Go to protobuf GH release website
- Download latest locally
- run `sha256sum`
- replace existing pinned hashes
- `make generate`
Deps upgrade:
- `go get -t -u all`
- repository moves aren't handled well automatically, fix manually
- repeat until no changes
From:
github.com/golang/protobuf v1.3.2
google.golang.org/grpc v1.17.0
To:
github.com/golang/protobuf v1.4.3
google.golang.org/grpc v1.35.0
google.golang.org/protobuf v1.25.0
About the two protobuf packages:
https://developers.google.com/protocol-buffers/docs/reference/go/faq
> Version v1.4.0 and higher of github.com/golang/protobuf wrap the new
implementation and permit programs to adopt the new API incrementally. For
example, the well-known types defined in github.com/golang/protobuf/ptypes are
simply aliases of those defined in the newer module. Thus,
google.golang.org/protobuf/types/known/emptypb and
github.com/golang/protobuf/ptypes/empty may be used interchangeably.
Notable Code Changes in zrepl:
- generate protobufs now contain a mutex so we can't copy them by value
anymore
- grpc.WithDialer is deprecated => use grpc.WithContextDialer instead
Go1.12 is now actually required by some of the dependencies.
