From 58286f454a049b2c74e8eb389b6ab1453d00f375 Mon Sep 17 00:00:00 2001 From: yusyus Date: Thu, 1 Jan 2026 20:41:28 +0300 Subject: [PATCH 1/3] fix: Handle symlinked README.md and CHANGELOG.md in GitHub scraper MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add _get_file_content() helper method to detect and follow symlinks - Update _extract_readme() to use new helper - Update _extract_changelog() to use new helper - Add 7 comprehensive tests for symlink handling - All 29 GitHub scraper tests passing Fixes #225 When README.md or CHANGELOG.md are symlinks (like in vercel/ai repo), PyGithub returns ContentFile with type='symlink' and encoding=None. Direct access to decoded_content throws AssertionError. Solution: Detect symlink type, follow target path, then decode actual file. Handles edge cases: broken symlinks, missing targets, encoding errors. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- src/skill_seekers/cli/github_scraper.py | 115 ++++++++----- tests/test_github_scraper.py | 213 ++++++++++++++++++++++++ 2 files changed, 283 insertions(+), 45 deletions(-) diff --git a/src/skill_seekers/cli/github_scraper.py b/src/skill_seekers/cli/github_scraper.py index 47f2196..0f77468 100644 --- a/src/skill_seekers/cli/github_scraper.py +++ b/src/skill_seekers/cli/github_scraper.py @@ -325,6 +325,58 @@ class GitHubScraper: raise ValueError(f"Repository not found: {self.repo_name}") raise + def _get_file_content(self, file_path: str) -> Optional[str]: + """ + Safely get file content, handling symlinks and encoding issues. + + Args: + file_path: Path to file in repository + + Returns: + File content as string, or None if file not found/error + """ + try: + content = self.repo.get_contents(file_path) + if not content: + return None + + #
