January 2026 monthly summary for apache/incubator-devlake. The GitHub API integration was enhanced to support private repositories for authenticated users by implementing owner-type awareness and an authenticated-user ID fetcher to route API calls to the appropriate endpoint. Key changes include: getOwnerInfo() to determine owner type (User/Organization), getAuthenticatedUserID() to identify the current user, and routing logic that selects the correct endpoint based on owner type: - Organization: /orgs/{owner}/repos - Authenticated user: /user/repos (includes private repos) - Other users: /users/{owner}/repos (public repos only) Added type=all to include all repository types. Refactored to listGithubOwnerRepos(owner) and renamed/updated related parameters. Commit: 14108386cf38d7afb96335dab887f82d3e59edc4. Closes #8680, #8681. Impact and value: Expanded data ingestion coverage by including private repos for authenticated users, improving analytics accuracy and enabling more complete downstream pipelines. Demonstrated REST API integration, conditional routing, and authentication handling; emphasized code quality through refactoring and clearer ownership semantics.
