Coreth > Subnet-EVM Sync Guidelines

[ceyonur]

Assume we're syncing to coreth v0.11.6 and coreth v0.11.3 was the last synced tag to subnet-evm (prior to this PR)

$ git checkout -b coreth-0.11.6-sync
$ git remote add coreth git@github.com:ava-labs/coreth.git
$ git config --add remote.coreth.fetch '+refs/tags/*:refs/tags/coreth/*'
$ git fetch --all
$ git diff coreth/v0.11.3 coreth/v0.11.6 > diff.patch
$ git apply diff.patch --reject --whitespace=fix

After applying the patch, then iterate manually over rejected files. at this point I preferred iterating over coreth diffs in a separate window and checked differences manually. I.e open 2 windows one:
1- within coreth that shows diffs between v0.11.3 to v0.11.6
2- subnet-evm
and compare missing differences in folders with those rejected files.

After finishing with rejected differences do these (keeping this order could make it easier)

• Replace coreth/ import paths with subnet-evm/ in .go files
• Make sure you've updated the LATEST_CORETH_VERSION in scripts/version.sh to the synced coreth version (v0.11.6)
• Change any Apricot/Banff/Cortina upgrades to SubnetEVM as SubnetEVM upgrade supposed to represent all of them combined.
• Fix tests if broken
• go mod tidy
• Compare current workspace with coreth-v0.11.6.
  • You can take a look at changed files between coreth-v0.11.6 and coreth-v0.11.3, to see if something missing in sync.

Even after everything there could be additional required changes or some changes need to be reverted manually.
