sentry_sdk/integrations/_wsgi_common.py

 import sentry_sdk
 from sentry_sdk._types import SENSITIVE_DATA_SUBSTITUTE
+from sentry_sdk._werkzeug import _get_headers
+from sentry_sdk.integrations.wsgi import get_client_ip, get_request_url


Circular import between wsgi.py and _wsgi_common.py will cause ImportError at runtime

The new import from sentry_sdk.integrations.wsgi import get_client_ip, get_request_url creates a circular dependency. wsgi.py imports _get_request_attributes from _wsgi_common.py (line 12 in wsgi.py), while _wsgi_common.py now imports from wsgi.py. When wsgi.py is loaded first, it will fail because _wsgi_common.py will try to import symbols from wsgi.py before they're defined. This will cause an ImportError or AttributeError at runtime.

Verification

Read both wsgi.py (lines 1-20) and _wsgi_common.py (lines 1-15) to confirm the import structure. wsgi.py imports _get_request_attributes from _wsgi_common.py at line 12. _wsgi_common.py now imports get_client_ip and get_request_url from wsgi.py at line 8. This is a classic circular import pattern that will fail at runtime.
