GitHub defaults to 30 items per page, so PRs with 31+ files would silently receive an incomplete file list -- causing MaxPrLocCondition (and every other condition reading changed_files) to undercount LOC and potentially pass when it should fail. - Set per_page=100 (GitHub max) and loop until all pages fetched - Gracefully return partial results if a later page errors - Add 6 tests covering multi-page, single-page, per_page param, reviews pagination, and error-on-page-2 scenarios --- src/integrations/github/api.py | 85 +++++++++++++------ tests/unit/integrations/github/test_api.py | 94 ++++++++++++++++++++++ 2 files changed, 155 insertions(+), 24 deletions(-) diff --git a/src/integrations/github/api.py b/src/integrations/github/api.py index 6fdc426..26d8c01 100644 --- a/src/integrations/github/api.py +++ b/src/integrations/github/api.py @@ -471,7 +471,11 @@ async def get_check_runs(self, repo: str, sha: str, installation_id: int) -> lis return [] async def get_pull_request_reviews(self, repo: str, pr_number: int, installation_id: int) -> list[dict[str, Any]]: - """Get reviews for a pull request.""" + """Get reviews for a pull request. + + Paginates through all pages to ensure the full review list is returned. + GitHub defaults to 30 reviews per page; max is 100. + """ try: token = await self.get_installation_access_token(installation_id) if not token: @@ -480,20 +484,34 @@ async def get_pull_request_reviews(self, repo: str, pr_number: int, installation headers = {"Authorization": f"Bearer {token}", "Accept": "application/vnd.github.v3+json"} - url = f"{config.github.api_base_url}/repos/{repo}/pulls/{pr_number}/reviews" + all_reviews: list[dict[str, Any]] = [] + page = 1 + per_page = 100 session = await self._get_session() - async with session.get(url, headers=headers) as response: - if response.status == 200: + while True: + url = ( + f"{config.github.api_base_url}/repos/{repo}/pulls/{pr_number}" + f"/reviews?per_page={per_page}&page={page}" + ) + async with session.get(url, headers=headers) as response: + if response.status != 200: + error_text = await response.text() + logger.error( + f"Failed to get reviews for PR #{pr_number} in {repo}.
