ref(integrations): route HTTP header filtering through data collection config by ericapisani · Pull Request #6788 · getsentry/sentry-python

ericapisani · 2026-07-08T19:38:54Z

_filter_headers follows the legacy send_default_pii/use_annotated_value behaviour when the data collection behaviour is not enabled in _experiments.

When data collection is enabled, it now delegates to _apply_key_value_collection_filtering from sentry_sdk.data_collection, so header scrubbing respects the new data_collection.http_headers.request allowlist/denylist/off configuration when data collection.

Work to scrub cookies in a more granular way will be tackled as part of PY-2581/#6741.

Fixes PY-2584
Fixes #6744

…n config `_filter_headers` previously used a hardcoded sensitive-header tuple and a `send_default_pii`/`use_annotated_value` toggle. It now delegates to `_apply_key_value_collection_filtering` from `sentry_sdk.data_collection`, so header scrubbing respects the new `data_collection.http_headers.request` allowlist/denylist/off configuration. Cookie and set-cookie headers are always redacted regardless of mode. Drops the now-unused `use_annotated_value` parameter from all call sites.

…ures The new lambda_functions_with_embedded_sdk fixture directories were missing the .gitignore that the other fixtures use to keep everything except index.py untracked. As a result, certifi and urllib3 packages installed by the test setup got committed, and ruff failed CI linting against them since they're unmodified third-party code. Add the missing .gitignore to each new fixture directory and remove the committed vendored packages; they are regenerated automatically at test time via `uv pip install --target`.

+        headers = _get_headers(asgi_scope)
+
+        request_data["headers"] = _filter_headers(
+            headers,
+            use_annotated_value=False,


This change was done because when if the headers are filtered with "allowlist" and no terms are provided, and the "host" header is present, then the constructed URL in _get_url below would contain [Filtered] within the URL.

Doing this ensures that it gets filtered from the headers to respect data collection, but still correctly appears in the url

As long as this doesn't affect current behavior should be ok 👍🏻

The streaming path no longer emits a client span when there is no current span (#6810), so unpack only the server span.

Lgtm! Left some suggestions.

This means this cookies logic will be updated later right?

Correct, it's part of #6797 😄

Why have this here in the first place? It doesn't look related to sensitive header behavior

It isn't related to sensitive header behaviour, but I had decided to add this in to make it clear that it isn't expected that user data would be present when data collection is enabled just yet.

Since assertions on these values appear in other tests within the file, I thought that not having assertions like these in a data collection-specific context would raise flags.

+def test_get_request_data_url_with_filtered_host(sentry_init):


Could we change these new test cases to set up a proper ASGI app, like the tests below? Just to make them a little less unit-testy.

I missed this earlier on, but I addressed this in https://github.com/getsentry/sentry-python/pull/6841/changes#diff-a4ca49dac9c5fcce27a4fb5fb53e5f8e764b807773ba7c5476d70d74a9789353 as

I can look into pulling that change into this branch, but if we wanted to merge this stack 1 big feature branch, it won't make a difference as it'll eventually be applied.
