This pull request fixes a bug in the csv differ that occurred when empty lines where present.

In the simplified view the diff is displayed by column. For this reason, each row needs the same amount of columns.
To solve this I padded too short rows with empty string

Walkthrough

The changes include modifications to the CsvDiffer class in the app/helpers/renderers/csv_differ.rb file, where a new method called padded_table has been added. This method ensures uniform column count across rows by padding shorter rows with empty strings. The constructor has been updated to use this method when parsing CSV data. Additionally, a new test case has been introduced in the SubmissionsControllerTest class to verify the handling of CSV files with empty rows, ensuring that the application correctly responds to such submissions.

Changes

File Change Summary
app/helpers/renderers/csv_differ.rb Added method padded_table(table) to ensure uniform column count in CSV rows; updated constructor to utilize this method for parsing CSV data.
test/controllers/submissions_controller_test.rb Added new test case Should be able to render submissions with csv's with empty rows to test rendering of submissions with empty rows in CSV files. Minor formatting changes made.

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

49-53: LGTM! Consider adding a comment for clarity.

The padded_table method effectively addresses the issue of handling rows with different column counts. It ensures that all rows have the same number of columns by padding shorter rows with empty strings.

Consider adding a brief comment explaining the purpose of this method, for example:

# Ensure all rows in the table have the same number of columns by padding with empty strings
def padded_table(table)
  # ... (existing implementation)
end
test/controllers/submissions_controller_test.rb (1)

471-479: Good addition, but consider enhancing the test assertions

The new test case effectively addresses the PR objective of handling CSV files with empty rows. It creates a submission with a relevant SQL query and a complex JSON result, which is good for testing edge cases.

However, consider the following improvements:

  1. Add more specific assertions to verify the content of the response, not just its status. For example, you could check for the presence of certain elements in the rendered HTML that indicate correct handling of empty rows.

  2. There's a minor typo in the test name: "csv`s" should be "csv's".

Here's a suggestion to improve the test:

 test 'Should be able to render submissions with csv`s with empty rows' do
   submission = create :wrong_submission, code: 'SELECT substr(name,4) FROM artist;',
                                          result: "{\"accepted\":false,\"status\":\"wrong\",\"description\":\"Test gefaald\",\"groups\":[{\"description\":\"Validatie\",\"badgeCount\":3,\"groups\":[{\"accepted\":false,\"groups\":[{\"description\":\"Resultaten vergelijken\",\"accepted\":false,\"tests\":[{\"expected\":\"name\\n$pyda\\n1000 Ohm\\n1001 Night Society\\n7 Days In Egypt\\nAC-DC\\nAbdullah Chhadeh\\nAboutou Roots\\nAdmiral Freebee\\nAfricanism All Stars\\nAfrikan Boy\\nAfro Celt Sound System\\nAfter Forever\\nAir\\nAlice Fitoussi\\nAlien The DJ\\nAmaryllis Temmerman\\nAmbeon\\nAmina Alaoui\\nAmália Rodrigues\\nAn Pierlé\\nAnathema\\nAni DiFranco\\nAnkata\\nAnn Christy\\nAnne Clark\\nAphex Twin\\nAphex Twin/James\\nAphex Twin/Richard James\\nApolo Novax\\nArbeid Adelt!\\nArithmetic\\nArmand\\nArno\\nArt Of Noise\\nArte'\\nAsian Dub Foundation\\nAtmosfear Featuring Mae B.\\nAwilo feat.

Line range hint 49-66: Summary: Effective solution for handling empty rows in CSV files

The changes introduced in this PR successfully address the issue of handling empty rows in CSV files. The new padded_table method ensures that all rows have the same number of columns, which is crucial for the CSV differ functionality. The integration of this method in the initialize function guarantees that both generated and expected CSV data are properly padded before further processing.

These modifications align well with the PR objectives and provide a clean, minimal solution to the problem. The implementation is efficient and doesn't introduce any apparent issues or side effects.

Great job on implementing this feature! The changes look good and should resolve the bug related to empty lines in CSV files.

LGTM! Changes align with PR objectives.

The integration of the padded_table method in the initialize method effectively addresses the issue of handling empty rows in CSV files. By applying this method to both @generated and @expected CSV data, we ensure that all rows have the same number of columns before further processing.

To further verify the impact of these changes, we can run the following script to check for any other occurrences of CSV parsing in the codebase that might benefit from similar padding:

This will help us ensure consistency across the codebase in handling CSV data with potential empty rows.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Search for other CSV parsing instances that might need padding

# Test: Look for CSV parsing in Ruby files
rg --type ruby 'CSV\.parse' -C 3

Strange that github says that the new lines aren't covered by tests while you did add one.

Seeing the large reduction in codecov percentage, something probably went wrong when uploading the coverage results. Happens sometimes
