Exercise two stale GitHub App requests against the same auth instance while the first token refresh holds the lock. Assert both requests reuse the replacement token and only one installation token is issued so the refresh_request lock behavior is covered directly.
Restrict installation token refresh retries to same-origin API requests that already carried a bearer token, preventing redirected requests from regaining authorization after Requests strips it. Stop retry-driven token minting once a replacement token has already been rejected, while preserving lock-based reuse for concurrent stale requests. Pass API origin context through app auth construction and add regression coverage for cross-origin redirects and repeated bad-credentials responses.
Catch installation token refresh failures inside refresh_request so the retry policy can return false instead of propagating an exception or mutating the request header. Log the failed refresh without including exception contents and add regression coverage proving the original Authorization header remains unchanged when refresh fails.
Validate the selected request API origin against the GithubInstallation API origin during auth initialization so retry matching and token minting cannot be configured for different hosts. Preserve the selected API URI for equivalent origins and add regression coverage for mismatched installation and request origins.
Replace the response-refreshed token sentinel with weak request-local tracking so repeated 401s for the same repaired request still fail closed without blocking a later independent request from refreshing the same installation token. This preserves the anti-churn behavior while allowing collection to recover when a subsequently issued request receives its own bad-credentials response.\n\nAlso reject plaintext HTTP API origins for GitHub App JWT and installation-token sessions so custom GitHub Enterprise hosts cannot send app credentials over an unencrypted connection. Add regression coverage for independent request recovery and plaintext host rejection.
Treat malformed successful GraphQL responses as retryable so transient empty or truncated payloads do not silently terminate repository pagination. Detect GraphQL requests by endpoint path as well as rate-limit headers so the retry policy still applies when GitHub omits GraphQL-specific response metadata. Add repository pagination failure context with the last cursor and emitted repository count, along with focused tests for malformed JSON recovery, multi-page repository emission, and terminal failure logging. Surface the REST repository size on GH_Repository nodes so empty repositories can be distinguished from repositories that lost branch data during collection.
WalkthroughThe change adds HTTPS API-origin validation, installation-token refresh retries, broader GraphQL retry detection, source API URI propagation, repository size preservation, and cursor-aware pagination logging with corresponding tests. ChangesGitHub API resilience and repository data
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The PR strengthens GraphQL retries and repository visibility, but API URLs containing query strings or fragments could produce an incorrect token endpoint, while failure logs may report the wrong repository cursor and complicate diagnosis of incomplete pagination. These are bounded follow-ups rather than high-impact merge blockers. Sequence Diagram(s)sequenceDiagram

Reject query strings and fragments in API URIs.
A value such as https://ghe.example/api/v3?debug=1 passes this validation. Lines 81-82 then create https://ghe.example/api/v3?debug=1/, so installation-token requests do not target the intended endpoint. Reject query strings, fragments, and user-info because this value is used as a base API URI.
Proposed fix
def _normalized_http_origin(url: str) -> tuple[str, str, int | None]:
parsed = urlparse(url)
scheme = parsed.scheme.lower()
- if scheme != "https" or not parsed.hostname:
+ if (
+ scheme != "https"
+ or not parsed.hostname
+ or parsed.username
+ or parsed.password
+ or parsed.query
+ or parsed.fragment

Track response cursors separately from request cursors. page_data.request.json["variables"]["after"] is the cursor used for the completed page, so a failure before the next page logs the wrong cursor. Set repository_cursor from repositories.pageInfo.endCursor. Update the test fixtures to include repositories.pageInfo and use the actual request cursors (None, then cursor-page-2).
