Addressed Issues:

Fixes #232

Screenshots/Recordings:

N/A (API query refactoring, input validation, and unit test suites)

Additional Notes:

  • Root Cause & Fix for HTTP 422: GitHub Search API interprets multiple org: qualifiers as an AND conjunction (org:A+org:B), returning 0 results or failing with HTTP 422 Unprocessable Content when an organization is inaccessible or private. Refactored ContributorProfilePage to execute individual queries per organization using Promise.allSettled() and deduplicate results by contribution ID.
  • Input Validation: Added strict validation for username parameter to reject empty, undefined, or null usernames immediately with a clean error before issuing network requests.
  • Detailed Error Messages: Enhanced fetchAllPages to parse GitHub error JSON bodies, surfacing specific error messages rather than a generic HTTP_422 string.
  • Resilient Analytics & Bus Factor: Filtered out anonymous git commits and entries without a valid login in buildAnalyticalModel, and guarded computeBusFactor against null or malformed contributor entries.
  • Test Suite: Added unit tests in src/pages/ContributorProfilePage.test.jsx (covering invalid username rejection, separated per-org queries, and detailed 422 message extraction) and src/services/analytics.buildAnalyticalModel.test.js. All 52 tests pass cleanly with 100% build verification.

⚠️ AI Notice - Important!

Used AI assistance to diagnose GitHub Search API query parameters and structure component test mocks. All query refactoring, edge-case guards, and test suites were executed and verified locally (52/52 tests passing, production build green).

Summary by CodeRabbit

  • Bug Fixes
    • Contributor searches now reject invalid usernames and show clearer GitHub API errors, including rate-limit errors.
    • Searches check organizations individually, keep successful results when others fail, warn about partial failures, and avoid duplicate contributions.
    • Analytics excludes contributors without valid logins and handles missing or invalid contributor entries safely.

Walkthrough

Contributor profile searches validate usernames and organizations, run separate queries per organization, and preserve successful results when other searches fail. Analytics filters invalid contributor entries. Tests cover search outcomes, analytics filtering, and declined SettingsPage confirmation.

Changes

Contributor Search

Layer / File(s) Summary
Validate search inputs and query organizations
src/pages/ContributorProfilePage.jsx, src/pages/ContributorProfilePage.test.jsx
The page validates usernames and organization logins, includes contributor-model organizations, and runs separate contribution and merged-PR queries per organization. Tests cover invalid usernames and separate queries.
Aggregate results and display search status
src/pages/ContributorProfilePage.jsx, src/pages/ContributorProfilePage.test.jsx
The page retains successful results, reports partial or total failures, prioritizes rate-limit errors, and deduplicates contributions by ID. It displays a warning for incomplete results. Tests cover API error messages and partial-result cases.

Analytics Contributor Filtering

Layer / File(s) Summary
Filter invalid contributors in analytics
src/services/analytics.js, src/services/analytics.buildAnalyticalModel.test.js
The analytical model excludes contributors without a login. Bus-factor calculations ignore null and non-object entries and return unknown risk when no valid entries remain. A test checks contributor lists and bus factor.

Settings Confirmation Test

Layer / File(s) Summary
Verify declined cache-clear confirmation
src/pages/SettingsPage.test.jsx
A test verifies that declining the confirmation does not call either cache-clearing function.

Explanation

The src/services/analytics.js changes filter anonymous contributors and alter bus-factor calculation. The src/services/analytics.buildAnalyticalModel.test.js additions test those analytics behaviors. The Settings-page confirmation test in src/pages/SettingsPage.test.jsx is also unrelated. Issue [#232] concerns the Contributor Intelligence GitHub fetch failure, and these changes do not support that fix.

A rabbit checks each login line,
Then sends two searches, batch by batch.
If one search fails, the good results stay,
And warning cards mark what is missing.
Null contributors hop out of the count,
While clean results make the charts take shape.

Review comments at @src/pages/ContributorProfilePage.jsx:
- Around line 214-221: Limit and pace GitHub search requests in the orgQueries
flow of ContributorProfilePage, including requests made by fetchAllPages during
pagination, rather than launching every organization’s issue and merged-PR
searches concurrently. Preserve the existing result handling while ensuring the
request schedule stays within GitHub’s search rate limits.
- Around line 252-258: Update the failure handling in ContributorProfilePage so
failures from individual organizations are reported even when anySuccess is
true. Preserve successful results and display a partial-results warning
identifying each failed organization; retain the existing all-failed error
behavior.
- Around line 185-186: Validate cleanUser and the organization value against
GitHub login-name syntax before using them in author: or org: search qualifiers.
Reject invalid values rather than relying on URL encoding, and preserve the
existing handling of valid logins.
- Around line 219-222: Update the organization query’s fetchAllPages calls so
failure of the merged-PR lookup does not reject or discard successful authored
items. Handle the results separately, retain authored contributions when the
merged lookup fails, and report that merged status is incomplete.
- Around line 173-175: Normalize organization values and deduplicate the final
list in the organization-processing chain before creating search requests, so
differently spaced entries that resolve to the same organization produce only
one request.

Review comments at @src/pages/ContributorProfilePage.test.jsx:
- Around line 81-88: Update the ContributorProfilePage test setup so
app.state.model.contributors[0].orgs contains only OrgA and OrgB. Replace the
loose fetchUrls count and presence checks with assertions that exactly one
issues query and one merged-PR query is made for each organization, with no
additional organization queries.

Review comments at @src/pages/SettingsPage.test.jsx:
- Line 25: Add a Clear All test in the existing SettingsPage tests that
overrides the beforeEach window.confirm mock to return false, then verifies
neither cacheClear nor clearAnalysis is called; leave the existing confirmation
behavior unchanged.

Review comments at @src/services/analytics.js:
- Line 67: Update buildAnalyticalModel to filter each repository’s contributors
before passing them to computeHealthScore or computeBusFactor and before storing
them in result.totalRepos[].contributors. Keep computeBusFactor’s existing
behavior for callers that pass contributor objects without logins.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

Limit concurrent search requests.

With no PAT, six organizations start at least 12 search requests immediately, before pagination. GitHub allows up to 10 unauthenticated search requests per minute; authenticated search also has a separate 30-request-per-minute limit. A profile with enough organizations can therefore rate-limit itself and return incomplete results or an error. Bound and pace these requests, including pagination, instead of starting every organization pair at once. (docs.github.com)
