#703 broke grpc interop testing

[ejona86]

I'm seeing build errors making the grpc_interop_dart container. The first failure I see is from 5:27:13 AM PDT and there was a successful build at 3:40:21 AM PDT. The error message is talking about SDK, and #703 changed that configuration, so looks to be the trigger.

Full log

Interesting snippet:

SLVR:   fact: every version of grpc from path requires SDK version ^3.2.0
SLVR:   conflict: every version of grpc from path requires SDK version ^3.2.0
SLVR:   ! grpc from path is satisfied by grpc from path
SLVR:   ! which is caused by "interop depends on grpc from path"
SLVR:   ! thus: version solving failed

Interesting that it seems to use Dart version 3.0.4, while the containing specifies stable, which would be 3.3.4. I will investigate.

[ejona86]

We might be using an old build of that Docker build container. The shell script is then run within.

If we rebuilt the container (and it picked up 3.3.4), would that still work for older versions of grpc-dart?

[mosuem]

The new grpc-dart version requires a minimum Dart version 3.2.0, but people using older versions of the SDK could still use older versions of grpc-dart.

Rebuilding the container sounds like a good idea!

Looks like it was rebuilt 2 weeks ago. Surely that would be new enough? https://github.com/grpc/grpc/pull/36329

I'm hoping https://github.com/grpc/grpc/pull/36556 resolves this. I hacked up the scripts a ton until it sorta looked like the results were correct.

[ejona86]

The most recent run passed!
