Addressed Issues:

Fixes #298

Screenshots/Recordings:

N/A

Additional Notes:

• Investigated why clicking the API Quota refresh icon in Settings falsely jumped the displayed quota to 5000 / 5000.
• Root cause: GitHub's GET /rate_limit endpoint does not track live core request consumption under PAT authentication and returns static 5000/5000, whereas authoritative x-ratelimit-* headers from REST API endpoints reflect real-time usage.
• Updated fetchRateLimit in src/services/github.js to inspect live x-ratelimit-limit, x-ratelimit-remaining, x-ratelimit-used, and x-ratelimit-reset via a lightweight zero-payload HEAD request, with a graceful fallback to /rate_limit.
• Updated refreshRateLimit in src/context/AppContext.jsx to persist the updated quota to localStorage (oe_rate_limit) and broadcast the rate-limit-update event so all components (e.g. Navbar) synchronize immediately.
• Enhanced SettingsPage to trigger live quota refresh on PAT save and deletion.
• Added comprehensive unit tests in src/services/github.test.js covering header parsing, fallback handling, 403 responses, and Bearer/token headers.
• Added test coverage in src/pages/SettingsPage.test.jsx verifying refresh button invocation and quota display (57/57 Vitest tests passing).

⚠️ AI Notice - Important!

Used AI assistance to investigate GitHub API rate-limit header discrepancies and structure unit tests in src/services/github.test.js. All implementation logic, edge cases, and test suites were reviewed, executed, and verified locally with 100% passing results.

Summary by CodeRabbit

  • New Features
    • Added live API quota checks, including remaining, total, and used quota details when available.
    • Quota checks refresh after saving or deleting an access token and can also be triggered manually.
    • Improved compatibility with different access-token formats, with a fallback quota check when the initial check cannot provide valid quota data.
  • Bug Fixes
    • Prevented storage errors and outdated quota responses from interrupting token updates or displaying stale quota information.

Walkthrough

Rate-limit lookup now checks GitHub response headers before using /rate_limit as a fallback. The app context handles quota refresh results and storage exceptions. Settings refreshes quota after a PAT is saved or deleted.

Changes

API Quota Refresh

Layer / File(s) Summary
Rate-limit lookup and fallback
src/services/github.js, src/services/github.test.js
fetchRateLimit preserves supported authorization prefixes and checks headers from HEAD /octocat. It derives used when needed and falls back to /rate_limit. Tests cover header parsing, fallback behavior, authorization, and network errors.
Settings refresh and state updates
src/context/AppContext.jsx, src/pages/SettingsPage.jsx, src/pages/SettingsPage.test.jsx
refreshRateLimit accepts a token override, rejects stale results, and updates quota state and storage for successful results. Storage failures do not interrupt the described event, expiry, or token-update paths. Settings refreshes quota after PAT save or deletion. Tests cover refresh interactions and displayed quota.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix · Severity of issue fixed: Medium

Suggested labels: Typescript Lang

Suggested reviewers: ri1tik

Merge Risk: 🔵 Low · up to 66a58

Saving a PAT can briefly leave Settings showing an outdated quota. This is a bounded issue, but the duplicate request should be removed while preserving quota invalidation.

Security architecture risk: 🔵 Low · up to 4a9a3

The change remains within the existing browser-to-GitHub connection. No authorization bypass or increased credential authority was identified. Quota updates can become stale across token changes, but inspected consumers use quota for display rather than access enforcement. Live authorization compatibility remains unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The demonstrated exposure is browser-origin quota state and requests using the supplied PAT against GitHub. The new quota request uses the same credential authority and host as before; inspected request execution does not gain authority from quota state.

Trust Boundaries and Controls

  • observed — Settings retains its existing GitHub validation before saving a nonempty token. Quota lookup now preserves Bearer or token prefixes. The Bearer test verifies header construction with a mocked response, not GitHub-side acceptance; that external contract remains a proof gap.

Resilience and Maintainability Implications

  • observed — The fallback handles HEAD responses without usable quota values, but a rejected HEAD fetch exits through the outer catch without trying /rate_limit. Existing quota then remains unchanged. This contains the failure to quota reporting rather than changing request authorization.

Hardening Proposals

  • proposed — Consider invalidating quota when credentials change and accepting results only from the current credential generation. Keep quota observational unless future enforcement introduces an explicit identity-bound contract.

Explanation

Issue #298 requires the Settings quota refresh to show the current quota instead of a false 5000/5000 value. fetchRateLimit now reads live x-ratelimit-* headers from a HEAD request and falls back to /rate_limit. refreshRateLimit updates React state, persists oe_rate_limit, and dispatches rate-limit-update. Settings also refreshes after PAT save and deletion. The current code supports the linked issue requirements.

Full details: Out of Scope Changes check

Explanation

The changes in src/services/github.js, src/context/AppContext.jsx, and src/pages/SettingsPage.jsx support live quota retrieval, state synchronization, token changes, and stale-request handling for issue #298. The related service and Settings tests verify this behavior. No unrelated change is evident in the reviewed scope.

Externalize the new quota prompt.

Move this user-visible string to the application’s i18n resources. As per path instructions, “User-visible strings should be externalized to resource files (i18n).”

hey @Ritik-Yadav, pushed updates addressing the edge cases (429 rate limit inspection, storage fail-safes, and stale token invalidation). vitest suite and all ci checks are all green now whenever you get a chance to take a look.

Remove the redundant quota refresh after savePat(token).

savePat(token) and refreshRateLimit(token) start separate quota requests. Their guards do not order these requests against each other. If the first request completes after the second, savePat can overwrite newer displayed and persisted quota with stale data.

Move token invalidation into savePat, then remove the second refresh. Keep the delete-path refresh because savePat('') does not fetch quota. Update the save test to expect no refresh call.

[BUG]: Refresh button in Settings falsely resets API quota to 5000/5000
