Automerge mismatched hashes bug
This repository is a reproduction of a mismatched hash bug in automerge. To try it yourself:
Setup
Call setup.sh with your desired branches
For example, if you want to test the current performance branch of automerge with the main branch
of automerge-rs, you would call:
$ ./setup.sh performance main
The script will then install everything, along with the correct branches you want to test. It will also build automerge (js).
Start the server
To compile and start the rust server, run npm start
Run the test
To run the tests: npm test
