Upgrade validator.

[regeda]

protoc-gen-validate is release under the v0.6.2:

https://github.com/envoyproxy/protoc-gen-validate/releases/tag/v0.6.2

The release contains the merge PR about "multi-error validation with
ValidateAll()":

bufbuild/protoc-gen-validate#468

Do we not version this anywhere? Someone else could come along and regenerate these files with their own version. We should version the generator somewhere.

Do you mean this file testing/testproto/test.manual_validator.pb.go?

[johanbrandhorst]

Sorry, I mean the version of the generator that generates the file. The versions of protoc-gen-validate.

[mweibel]

sorry for the noise, but what's the status here? Would be great to have this merged 🎉

[johanbrandhorst]

We added support for ValidateAll in v2 here: 5b8ad84. If that's what this is about we can close this.

[mweibel]

yes, it's about that 👍 I didn't know about v2 yet, is that usable yet?

[johanbrandhorst]

It should be useable, yeah, but we haven't made stable release version of it yet. There are a few oustanding issues still 😬. https://github.com/grpc-ecosystem/go-grpc-middleware/issues?q=is%3Aissue+is%3Aopen+v2+label%3Av2
