When the package @dcl/sdk is built, @dcl/rollup and @dcl/ecs are versioned.
@dcl/sdk collects a dependency of these three packages to be able to build scenes and libraries.
ECS 6 dev support
The ECS 6 lives in the 6.x.x branch, there will no longer be new features but it's available for fixes or patches.
With a PR to 6.x.x, you can test the build with the S3 publish, but it'll be necessary to create a release for propagating under decentraland-ecs@latest.
Updating golden files (.crdt)
Most changes to the codebase impose a change in the amount of opcodes executed in the actual scene. We use a QuickJS virtual machine to benchmark opcodes. Although, it is not representative of the reallity of optimized JIT virual machines, it is a good measurement to generate awareness of the impact of the pull requests across SDK developers.
To re-create the files, running make build update-snapshots should suffice. If an discrepancy between the local results and the CI results appears, there is a heavier command make deep-clean-and-snapshot that will do the trick. Execute it with extreme care, since it will clean your git state.
