README-rewritten-jdk-history

Sometimes openjdk/jdk and openjdk/jdk11u have their history rewritten incompatibly. :-(


Here is how Mike dealt with that problem the last time it happened.

# Do this:

cd $t/libraries
mv jdk-fork-openjdk jdk-fork-openjdk-BEFORE-JDK-FORCE-PUSH
git clone git@github.com:openjdk/jdk.git jdk-fork-openjdk
cd jdk-fork-openjdk
# May need to update the commit number; see the README file
git checkout da75f3c4ad5bdf25167a3ed80e51f567ab3dbd01

cd $t/libraries
mv jdk-fork-typetools-branch-master jdk-fork-typetools-branch-master-BEFORE-JDK-FORCE-PUSH
# Browse to https://github.com/typetools/jdk/settings and delete the repository
# Browse to https://github.com/openjdk/jdk and fork the repository to typetools
cd $t/libraries
git clone git@github.com:typetools/jdk.git jdk-fork-typetools-branch-master
cd jdk-fork-typetools-branch-master
git reset --hard da75f3c4ad5bdf25167a3ed80e51f567ab3dbd01
git push -f
cd $t/libraries
rsync -a --exclude '.git' jdk-fork-typetools-branch-master-BEFORE-JDK-FORCE-PUSH/ jdk-fork-typetools-branch-master/
(cd jdk-fork-typetools-branch-master && git add . && git commit -m "Pluggable type-checking annotations" && git push)

cd $t/libraries
rm -rf jdk11u-fork-openjdk
cd /scratch/mernst/clones/types/libraries
git clone git@github.com:openjdk/jdk11u.git jdk11u-fork-openjdk

cd $t/libraries
mv jdk11u-fork-typetools jdk-fork-typetools-BEFORE-JDK-FORCE-PUSH
# Browse to https://github.com/typetools/jdk11u/settings and delete the repository
# Browse to https://github.com/openjdk/jdk11u and fork the repository to typetools
cd $t/libraries
git clone git@github.com:typetools/jdk11u.git jdk11u-fork-typetools-branch-master
# Update it from its upstreams in the usual way.

At each URL:
 * Queue the project in hopes that will start automatic building for each commit.
 * If the above doesn't work, change the instructions to the below:
 * Delete and re-create the pipeline, because of apparent caching problems when checking out the projects.
