From b22e4e4bb781af432bb6c03472d567b1f10648f1 Mon Sep 17 00:00:00 2001 From: sreejesh Date: Fri, 4 Jul 2025 12:14:03 +0100 Subject: [PATCH 01/12] feat: support automatic GitHub App token refresh for app_auth (#977) This commit addresses issue #977 by introducing an automatic token refresh mechanism for GitHub App-based authentication. When using short-lived GitHub App tokens (JWT + installation token), the provider now refreshes the token transparently before expiry, avoiding auth failures during long-lived Terraform runs or plan/apply cycles. Key enhancements: - Added `NewRefreshingTokenSource()` to wrap token acquisition and refresh. - Refactored `Config.AuthenticatedHTTPClient()` to detect GitHub App env vars (`GITHUB_APP_ID`, `GITHUB_APP_INSTALLATION_ID`, `GITHUB_APP_PEM` or `GITHUB_APP_PEM_FILE`) and enable refreshable OAuth2 token source. - Fallbacks gracefully to using a Personal Access Token (PAT) when `GITHUB_TOKEN` is set. - Environment-based discovery of GitHub App credentials avoids Terraform schema changes. - Added unit tests covering: - Refreshing logic (initial, expired, and error conditions) - Config behavior (anonymous and authenticated client behavior) - Error cases for missing App ID, installation ID, or PEM - No change to existing configuration schema or behavior for current users using PAT-based authentication. This upgrade enables more resilient GitHub App usage and prepares the provider for robust automation scenarios. --- github/config.go | 99 +++++++++++++++++- github/config_refresh_token_test.go | 157
