Ithaca2

Context

New snapshot of Ithaca protocol (replacing !4078 (merged)) that includes fix from !4181 (merged).

Created using the following commands.

1. Snapshot new protocol and copy to a temporary folder.

$ git checkout 9b756fa0069483b04a93de2e7b6ca7bb30678a7a # head of proto-i branch 
$ ./scripts/snapshot_alpha.sh ithaca_012
$ cp -r src/proto_012_Psithaca /tmp/proto_012_Psithaca
$ git checkout .
$ git clean -fd

2. Rename protocol to match new hash.

$ git checkout master
$ git checkout -b ithaca2
$ git mv src/proto_012_PsiThaCa src/proto_012_Psithaca
$ for f in $(find . -name '*PsiThaCa*'); do mv $f ${f/PsiThaCa/Psithaca}; done

$ git add --all
$ git commit -m "Proto: rename protocol"

3. Update protocol hash everywhere.

$ grep -r PsiThaCaT47Zboaw71QWScM8sXeMM7bbQFncK9FLqYc6EKdpjVP . | grep -v './.git/' | cut -f1 -d: | xargs sed -i s/PsiThaCaT47Zboaw71QWScM8sXeMM7bbQFncK9FLqYc6EKdpjVP/Psithaca2MLRFYargivpo7YvUr7wUDqyxrdhC5CQq78mRvimz6A/g
$ grep -r PsiThaCa . | grep -v './.git/' | cut -f1 -d: | sort -u | xargs sed -i s/PsiThaCa/Psithaca/g

$ git add --all
$ git commit -m "Everywhere: update protocol hash"

4. Replace lib_protocol code (not touching other folders - to not lose patches applied on master since Ithaca snapshot).

$ rm src/proto_012_Psithaca/lib_protocol/*
$ cp /tmp/proto_012_Psithaca/lib_protocol/* src/proto_012_Psithaca/lib_protocol/
$ cp /tmp/proto_012_Psithaca/lib_protocol/test/* src/proto_012_Psithaca/lib_protocol/test/
$ git checkout  src/proto_012_Psithaca/lib_protocol/dune

$ git add --all
$ git commit -m "Proto: update protocol code"

5. Backport changes to folders outside lib_protocol separately (to preserve other changes done on master).

$ git show 01fa37d7fe928a548009e468a18de26abdd7bf5a | sed 's#src/proto_alpha#src/proto_012_Psithaca#g' | patch -p1
$ git commit -am "Proto/Client: backport changes from !4182"

$ git show 8cee92435832a7904129126e67eaf2990f476b59 -- src/proto_alpha/lib_client | sed 's#src/proto_alpha#src/proto_012_Psithaca#g' | patch -p1
$ git commit -am "Proto/Client: backport changes from !4181"
