What

The commit for the next ghostnet upgrade is: d517020b

Steps

Freeze the kernel

Prepare the ghostnet kernel:

$ git checkout RELEASE_COMMIT
$ make -f etherlink.mk evm_kernel.wasm
$ cp evm_kernel.wasm etherlink/kernel_evm/kernel/tests/resources/ghostnet_evm_kernel.wasm

Update the constant ghostnet_evm_commit in tezt/lib_tezos/constant.ml:

let ghostnet_evm_commit = "RELEASE_COMMIT"

Freeze the node

Copy dev into prod:

$ cd etherlink/bin_node
$ rm -rf lib_prod
$ cp -r lib_dev lib_prod

Replace the various dev mention:

$ find . -type f -exec sed -i 's/dev\"/prod\"/g' {} +
$ find . -type f -exec sed -i 's/\_dev/\_prod/g' {} +

Update manifest:

$ cd ../../
$ make -C manifest

At this point you might need to manually update the dependencies in manifest.ml. You simply have to copy the list of dependencies from dev to prod.

Remove migration code if any

Any migration code should be removed and goes back to:

if STORAGE_VERSION == current_version + 1 {
  // MIGRATION CODE - START
  // MIGRATION CODE - END
  store_storage_version(host, STORAGE_VERSION)?;
  return Ok(MigrationStatus::Done);
}

Test

Simply compile everything and run the tests!

$ make octez-evm-node && make -f etherlink.mk evm_kernel.wasm
$ tezt -f evm_sequencer.ml -f evm_rollup.ml -j 4 --keep-going

Checklist

Freeze the kernel and node changelogs and create the NEXT section.
Freeze the kernel.
Freeze evm-node.
