Meeting minutes

to 1. @lurtz

• SOCOM merged to main
• IPC is in progress, method calls can be forwarded (IPC designed asynchronous)
• Architecture: https://github.com/orgs/eclipse-score/discussions/1984

to 2. @JochenSatETAS

PR is in works but internal discussion still ongoing. Review request will be stated as soon as internal discussions are finished.

to 3. @LittleHuba

Cache size is now at 50GB.
Caching is quirky:

• feature branches can only read caches created on their branch and on main branch.
  -> We now activate the push trigger on the main branch to heat cache
• Cache artifacts are not updated once created
• When a build file is modified then the existing disk cache is completely ignored and recreated

Stream API proposal is being prepared
Current AsyncReceive is too limited for some use cases
@bharatGoswami8 will post the related PR in a comment once ready.

to 5. @LittleHuba

Dev-dependency versions are not bumped for the release - they are not relevant for our users: https://github.com/eclipse-score/communication/blob/main/examples/MODULE.bazel

For other dependencies we go with the concept of "use the oldest you can" as documented by Bazel as best practice.
This might currently mean that newer versions break without us knowing.
In the future we must have test that verify version windows that we support.
