Fix bug with marshalling experiments

[ridiculous]

Allows this to work:

Marshal.load(Marshal.dump(Scientist::Default.new("foo")))
#=> ArgumentError: wrong number of arguments (given 1, expected 0)
#=> from /Users/ryan.buckley/.rvm/gems/ruby-2.7.8@envoy-web/gems/scientist-1.6.3/lib/scientist/experiment.rb:334:in `marshal_load'

[Fe1777]

It looks like you're working on a GitHub issue related to the scientist repository, specifically addressing a bug with marshalling experiments. The issue and branch details are:

• Issue: Fix bug with marshalling experiments #259
• Branch: ridiculous-patch-1
• Base: main

Here’s a guide on how you can fix the bug and submit the changes via a pull request.

Step-by-Step Guide

1. Clone the Repository

If you haven’t already cloned the repository, you can do so with:

git clone https://github.com/github/scientist.git
cd scientist

2. Create a New Branch

Create a new branch based on the existing feature branch (ridiculous-patch-1):

git checkout -b fix-marshalling-experiments ridiculous-patch-1

3. Identify and Fix the Bug

Find the area of the code where the marshalling of experiments is happening, and determine the root cause of the bug. This might involve:

1. Understanding how experiments are currently marshalled.
2. Identifying why the current approach is failing.
3. Implementing the correct solution to handle marshalling properly.

Example Changes

Suppose the issue is with converting an experiment object to JSON (as a common use case), the bug could be in how object attributes are being handled or formatted.

Here’s a pseudo-code representation of what you might need to do:

# Assuming we're dealing with a Ruby object

class Experiment
  attr_accessor :name, :data

  def initialize(name, data)
    @name = name
    @data = data
  end

  # Fix the method for marshalling to JSON
  def to_json(*options)
    {
      'name' => @name,
      # Properly handle complex data structures
      'data' => @data.is_a?(Hash) ? @data.transform_keys(&:to_s) : @data
    }.to_json(*options)
  end
end

# Example 'marshalling' fix test case
experiment = Experiment.new("test_experiment", { a: 1, b: 2 })
puts experiment.to_json

4. Save and Test Your Changes

Make sure to save your changes and thoroughly test them:

• Write unit tests to ensure the marshalling works correctly.
• Run the test suite to verify that existing functionality has not been broken.

Example test (using a hypothetical testing framework):

require 'minitest/autorun'

class TestExperiment < Minitest::Test
  def test_to_json
    experiment = Experiment.new("test_experiment", { a: 1, b: 2 })
    expected_json = '{"name":"test_experiment","data":{"a":1,"b":2}}'
    assert_equal(expected_json, experiment.to_json)
  end
end

Run the tests:

ruby test/test_experiment.rb

5. Commit Your Changes

Once you’re satisfied with your changes, commit them:

git add .
git commit -m "Fix bug with marshalling experiments"

6. Push the Changes to GitHub

Push your changes to the specific branch:

git push origin fix-marshalling-experiments

7. Create a Pull Request

Now, create a pull request on GitHub from your branch (fix-marshalling-experiments) to the original branch (ridiculous-patch-1).

1. Navigate to the repository on GitHub.
2. Locate your branch (fix-marshalling-experiments).
3. Click Create Pull Request.
4. Ensure the base branch is ridiculous-patch-1 and the compare branch is fix-marshalling-experiments.
5. Provide a descriptive title and detailed comment about the fix.

Pull Request Example
