I got this error message:

git-bob ask gpt-5 to think about this ans propose a fix

Thanks for the stack trace — this happens when GitHub returns “encoding: none” (e.g. for large files), so PyGithub’s decoded_content assertion trips. A small fix is to make decode_file() fall back to the download_url (or blob API) and only raise UnicodeDecodeError for true binary files.

Proposed change:

def decode_file(file):
    # Normal path for base64-encoded contents
    try:
        return file.decoded_content.decode()
    except AssertionError:
        # Fallback for "encoding: none" (e.g., large files)
        import os
        import requests
        import base64

        token = os.getenv("GITHUB_API_KEY")
        headers = {"Authorization": f"token {token}"} if token else {}

        # 1) Try raw download URL
        download_url = getattr(file, "download_url", None)
        if download_url:
            r = requests.get(download_url, headers=headers)
            r.raise_for_status()
            # Will raise UnicodeDecodeError for binary files, which is desired
            return r.content.decode()

        # 2) Fallback to Git blob API (always base64)
        git_url = getattr(file, "git_url", None)
        if git_url:
            r = requests.get(git_url, headers=headers)
            r.raise_for_status()
            data = r.json()
            if data.get("encoding") == "base64" and "content" in data:
                content = base64.b64decode(data["content"])
                return content.decode()

        # If neither path worked, re-raise for caller to handle
        raise

Short note: this keeps existing behavior — text returns as str; binary raises UnicodeDecodeError, which your caller already handles.

ok cool. We'll try it out

git-bob implement this
