Make proto-tools script creates unbuildable proto files

[AdityaSripal]

Summary of Bug

I reinstalled my proto-tools with the new Makefile script and while everything downloaded just fine, and running the proto commands works fine. The final result is unbuildable.

To see an example of the pb.go files this build generated, see this commit: c2b7b56

Trying to build fails on this commit as you can see in the github checks on that commit.

I had to checkout to a version of master before #7294 and reinstall my proto tooling there to get my branch working again.

Operating System: Darwin 19.4.0

Steps to Reproduce

# on master
rm proto-tools-stamp
make proto-tools
make proto-gen
make build

# Result
➜  cosmos-sdk git:(master) ✗ make build
go install -mod=readonly ./...
# github.com/keybase/go-keychain

I also noticed that in either case, make proto-format was not working for me: #7320 (comment).
proto-tools downloads clang-format version 10.0.1 for me. I don't know if that is the correct version or not.

It's possible something I did in my setup was wrong, but I removed all the executables proto-tools should download and reran the script and still got the same error, so not sure what's happening.

Hold on, your build's job proto-check-breaking-docker leverages a docker-ized version of buf. Which I didn't touch at all.
And from the build log shown here, there's clearly a mismatch between such adocker-ized version of buf and the local version of buf we've been using for a long time (I didn't touch that either).

@aaronc @clevinson any advice here? Can anyone reproduce this issue somehow?

The docker command stays up to date with the latest buf changes.

To mitigate this someone should create a docker file that builds proto stubs. It seems there are countless issues with the current design because of the use of so many tools. We did this on tendermint to mitigate this issue when the work on proto first started. It has saved the team time in producing the proto files

[tac0turtle]

buf now has support for protoc buf protoc. It may be beenficial to migrate to it from normal protoc as they both do the same thing

I had this issue locally as well, so I don't think docker is the problem?

Has anyone else been able to reproduce on a Mac?

[colin-axner]

I can reproduce this on Linux, see comment

[fedekunze]

I'm experiencing this issue too on Mac... See #7425 (review)

[fedekunze]

adding this to 0.40 milestone @clevinson @amaurymartiny

[amaury1093]

I think we all agree that we should 1/ remove make proto-tools and 2/ run make proto-gen using Docker: #7410 (comment)

I'm assigning this to @marbar3778, lmk if you prefer someone from the Regen team to take care of it.
