# Introduction

This repo reproduces an issue of the [`debug` gem](https://github.com/ruby/debug) as described below.

## Issue Description

Breakpoints added via VS Code seems to be lost after Rails' code reload.

## Steps

1. Clone this repo.

1. Run `$ bundle install`.

1. Run `$ bundle exec bin/rails db:migrate RAILS_ENV=development`.

1. Run `$ bundle exec rdbg -O -n -c -- bundle exec bin/rails s` to run the server with debugger in server mode.

1. Press `F5` to attach VS Code to the debugger.

1. Go to `app/controllers/posts_controller.rb` and place an VS Code breakpoint at line `6`.

    ```rb

    def index

      @posts = Post.all # set the breakpoint at this line

    end

    ```

1. Verify the breakpoint can be hit:

    1. In browser, visit http://localhost:3000.

    1. See the breakpoint being hit.

    1. Press `F5` again to continue the program.

1. Add `puts "foo"` at `app/controllers/posts_controller.rb:6`

    ```rb

    def index

      puts "foo"

      @posts = Post.all

    end

    ```

1. Refresh the page in browser.

## Expected Behaviour

The breakpoint should still be hit.

## Actual Behaviour

The breakpoint would be ignored.

## Other Notes

From DAP server logs, it looks like the debugger does receive updated `setBreakpoints` request:

```

#25986:[>] {"command":"setBreakpoints","arguments":{"source":{"path":"/Users/hung-wulo/src/github.com/st0012/debug-issue/app/controllers/posts_controller.rb","name":"posts_controller.rb","sourceReference":0},"lines":[6],"breakpoints":[{"line":6}],"sourceModified":true},"type":"request","seq":13}

#25986:[<] {"type":"response","command":"setBreakpoints","request_seq":13,"success":true,"message":"Success","body":{"breakpoints":[{"verified":true}]},"seq":977}

```

But the breakpoint wasn't actually added.
