[shuhaowu]

Can you create a PR with only the fix for mediumint?

[HemeraOne]

Done!

[shuhaowu]

Thanks for the PR. Is it possible for you to add a test here? https://github.com/Shopify/ghostferry/blob/master/test/integration/types_test.rb

[HemeraOne]

I can't get the ruby test thing to work on my machine, so I'm afraid I can't

[shuhaowu]

Is this needed? Can we not just use https://github.com/go-mysql-org/go-mysql/blob/master/mysql/parse_binary.go#L22-L31

[HemeraOne]

It would take a int32 to byte conversion, which in itself would require some code which you might not want to put in that location as well

Do you have an error? For ruby testing, you can use nix-shell to run it if you have that. Otherwise a standard install of Ruby with bundler should just work.

An error occurred while installing mysql2 (0.5.3), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.5.3' --source 'https://rubygems.org/'` succeeds before bundling.

In Gemfile:

there seems to be more issues, will look further tomorrow

[shuhaowu]

you need mysql client development headers installed on your computer to install mysql2. libmysqlclient-dev for something like ubuntu.

there seems to be more issues, will look further tomorrow

Having a comprehensive integration test may help you iron out all the issue in one go.
