2. Detailed Technical Analysis

2.1 Code Logic Deep-Dive

Core Logic Changes

frontend/app/components/panel/manage-explorer.js - blockFeatureOntologiesTreeEmbedded

• Submitted PR Code:

  -      .catch(error => { dLog(fnName, error.responseJSON.error || error); return Promise.resolve({}); });
  +      .catch(error => { dLog(fnName, error.responseJSON?.error || error); return Promise.resolve({}); });

• Analysis:
  • Current logic and potential issues:
    • The original code assumes error.responseJSON is always defined, which could lead to runtime errors if it is undefined.
  • Edge cases and error handling:
    • Using optional chaining (?.) ensures that the code does not throw an error when error.responseJSON is undefined.
  • Cross-component impact :
    • None.
  • Business logic considerations :
    • None.
  • LlamaPReview Suggested Improvements:

    .catch(error => {
      dLog(fnName, error.responseJSON?.error || error);
      return Promise.resolve({});
    });

  • Improvement rationale:
    • Technical benefits:
      • Prevents runtime errors by safely handling undefined properties.
    • Business value:
      • Enhances application robustness and reliability.
    • Risk assessment:
      • Low risk, as it is a minor improvement to error handling.

frontend/app/components/panel/manage-genotype.js - sampleFiltersCopy

• Submitted PR Code:

  -        this.selectedSampleRefreshDisplay(/*sampleFilterTypeName*/undefined);
  +        ! this.isDestroying && this.selectedSampleRefreshDisplay(/*sampleFilterTypeName*/undefined);

• Analysis:
  • Current logic and potential issues:
    • The original code does not check if the component is being destroyed, which could lead to unnecessary function calls.
  • Edge cases and error handling:
    • Adding a check for this.isDestroying prevents unnecessary function calls when the component is being destroyed.
  • Cross-component impact :
    • None.
  • Business logic considerations :
    • None.
  • LlamaPReview Suggested Improvements:

    !this.isDestroying && this.selectedSampleRefreshDisplay(/*sampleFilterTypeName*/undefined);

  • Improvement rationale:
    • Technical benefits:
      • Prevents unnecessary function calls, improving performance and state management.
    • Business value:
      • Ensures the application remains in a consistent state.
    • Risk assessment:
      • Low risk, as it is a minor improvement to state checking.

  const mockError = { responseJSON: undefined };
  const result = await blockFeatureOntologiesTreeEmbedded();
  expect(result).toEqual({});
});

// Example unit test for manage-genotype.js
test('sampleFiltersCopy does not call selectedSampleRefreshDisplay when isDestroying is true', () => {
  const component = {
    isDestroying: true,
    selectedSampleRefreshDisplay: jest.fn(),
  };
  component.sampleFiltersCopy();
  expect(component.selectedSampleRefreshDisplay).not.toHaveBeenCalled();
});
