Python keeps only the last binding for a name, so when a file defines the same
test twice the earlier one is unreachable. pytest cannot collect a function that
no longer exists, so nothing reports it and the file still looks like it covers
the scenario.
These ten are cases where the two definitions have different bodies, meaning a
real test was replaced rather than duplicated. Each is renamed to say what it
actually covers, which makes it reachable again:
- test_gemini_frequency_penalty: the dead copy checks the parameter is listed in
get_supported_openai_params for vertex_ai; the survivor checks get_optional_params
maps a value for gemini. Different function and different provider.
- test_async_log_success_event_adds_to_queue and the failure variant: the dead
copies run without mocking asyncio.create_task, so they exercise the real task
path the survivors mock out.
- test_async_send_batch_triggers_tasks: the dead copy asserts send is not awaited
directly; the survivor asserts create_task was called.
- test_model_id_in_required_metrics: the dead copy checks the model_id label on
twelve further metrics the survivor dropped.
- test_anthropic_messages_pt_file_block_preserves_cache_control: the dead copy
passes model and llm_provider explicitly and uses real base64 PDF content.
- test_translate_streaming_openai_chunk_to_anthropic_with_thinking: the dead copy
covers thinking_delta; the survivor covers signature_delta.
- test_client_initialization and test_client_without_api_key: the dead copies
assert the resource clients are wired with the right base URL and key; the
survivors only construct the object.
- test_client_initialization_strips_trailing_slash: the dead copy constructs
ModelsManagementClient directly rather than going through Client.
Verification: collecting the seven touched files gives 401 node IDs before and
411 after, the ten new names and nothing else, with nothing lost. All ten pass.
Running the touched files in full gives 299 passed, and test_optional_params.py
goes from 111 passed to 112.
Two further shadowed definitions were left alone rather than renamed: the dead
copies of test_prompt_caching and test_cost_calculator_with_base_model_with_router
have no assertions at all, one being a bare pass and the other a lone import, so
restoring them would add tests that cannot fail.
Three groups, all verified by running the suite rather than by inspection.
18 files whose every test function carries an unconditional @pytest.mark.skip,
39 test functions in total. They are collected on every CI run and always skip,
so they advertise coverage the suite does not have. Reasons on the marks include
"AWS Suspended Account", "lakera deprecated their v1 endpoint" and "moved to
using 'otel' for logging"; 26 of the marks predate 2025.
30 test functions with a byte-identical body and identical decorators to a
sibling in the same file and class, differing only in name. Deleting one of each
pair removes no coverage. Four further candidates were excluded because they
override an inherited test, where deleting the override un-shadows the base
class implementation instead of removing a duplicate.
9 test functions that a later definition of the same name shadows, so Python
never binds them and pytest cannot collect them.
One file that is a demo script rather than a test; its own docstring says to run
it with python.
Verification: collecting the 26 edited files gives 2,492 node IDs before and
2,462 after. The 30 duplicate deletions account for exactly 30 removals, the 9
shadowed deletions account for 0 (confirming at runtime that they were never
collectable), nothing unexplained disappeared, and nothing new appeared. No
other test or module imports any deleted symbol.
Drop the transform overrides that swapped response.usage to the chat
shape, which broke the /v1/responses client contract. Provider extras
like server_side_tool_usage_details already survive validation via
ResponseAPIUsage extra fields, so the shared usage bridge now carries
them onto the bridged chat Usage generically. The web_search_call
output gate also reads dict output items, since items that fail SDK
validation stay plain dicts, and the chat path gains billing tests.
Record supports_tool_search on the Bedrock Claude entries in both cost
map files and have _supports_tool_search_on_bedrock read it first via
the provider-resolved capability lookup, keeping the name patterns as a
fallback for ARNs and ids the map cannot resolve. Threads the flag
through ModelInfoBase and drops a dated remark from the pattern list
Claude Code drives Opus 4.7 with thinking {"type": "adaptive"} plus
output_config {"effort": "max"}. The anthropic-to-openai adapter
forwarded thinking verbatim for Claude models but dropped output_config,
and Bedrock Converse streams zero reasoningContent blocks for adaptive
thinking without an effort tier. Forward the effort subset of
output_config for Bedrock targets, accept it in the converse supported
params, and map it with the model's effort ceiling applied. Re-enable
the skipped e2e compat cell that catches this
Bedrock InvokeModel rejects tool_search_tool_* tool types unless the
request body carries the tool-search-tool-2025-10-19 beta. The model
allowlist gating that beta omitted Haiku 4.5 (and Opus 4.7, supported
since launch per live verification), so every tool-search request on
those models got a Bedrock 400. Add both to the allowlist and re-enable
the e2e compat cell that caught it.
* fix(bedrock): reject Anthropic server-side web_search tool with actionable error
Bedrock's Anthropic Messages endpoints cannot execute Anthropic's
server-side web_search tool, so forwarding it returns an opaque
"The provided request is not valid" 400 from Bedrock. Fail fast in the
invoke transform with an error that names the unsupported tool, the
model, and links the web search interception docs as the fix.
* refactor(bedrock): address review nits on web_search guard typing
xAI already converts Responses usage to chat Usage so web_search_calls survive
cost tracking. The chat completions bridge then re-ran the Responses usage
transform and crashed on missing input_tokens. Pass through already-chat Usage
and chat-shaped dumps instead
Gate web search like OpenAI (output/annotations/web_search_requests).
xAI uses server_side_tool_usage_details only for per-call cost math, with
web_search_requests mirrored in llms/xai for existing gate compatibility.
Treat positive web_search_calls as a web-search signal in built-in tool
cost gating, and mirror counts onto prompt_tokens_details.web_search_requests
when attaching xAI tool usage details so charges are not skipped.
Use usage.server_side_tool_usage_details.web_search_calls at $5/1k calls
instead of legacy num_sources_used/web_search_requests. Preserve tool usage
details through Responses usage transform for accurate response cost.
HTTPHandler.post and AsyncHTTPHandler.post call raise_for_status before returning, so the status_code != 200 branches after the create and cancel POSTs could never run. Non-2xx already surfaces as httpx.HTTPStatusError from inside the client. The checks after GETs stay: the get helpers return without raising. Tests that faked a non-raising POST response are replaced by HTTPStatusError propagation coverage.
* fix(websearch): restore snippet text in native web_search_tool_result blocks (LIT-5315)
The build_web_search_tool_result_block method copied url/title/page_age but
hardcoded encrypted_content to empty string, never reading SearchResult.snippet.
This left every native block content-free, forcing clients to web_fetch each
result to recover evidence—the reported symptom.
The Anthropic spec carries page text only in encrypted_content (an opaque
server-issued blob we cannot mint), so snippet is emitted as an additive key
alongside the spec fields. encrypted_content stays empty rather than holding
plaintext, which would assert encryption semantics that don't hold.
The anthropic SDK's BaseModel sets extra='allow', so the additive snippet key
survives SDK parsing. litellm has no typed model for web_search_result at all,
so nothing drops it internally. Turn-2 replay behavior is unaffected: the
empty encrypted_content already exists today.
Tests:
- Updated test_shape_with_results to assert snippet present
- Added test_snippet_carried_for_every_result to cover multi-result ordering
- Added test_missing_snippet_degrades_to_empty_string for edge case
- Mutation check: reverting source-only yields 3 test failures, restored to 117 passed
Fixes: LIT-5315

* fix(websearch): make synthesized web_search blocks replayable by native clients
Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>
* fix(websearch): flatten a resultless replayed search block so Bedrock accepts the next turn
The flatten added for LIT-5315 bails when the replayed web_search_tool_result
carries an empty content list, but that is exactly what the interceptor emits
when a search legitimately returns nothing and when a search raises. The block
survived into the outbound body, Bedrock rejected the tag, and the conversation
died on the following turn just as it did before the flatten existed.
An empty content list has no encrypted_content to respect and no evidence to
preserve, so it flattens safely, and its paired server_tool_use goes with it.
The rendered text now says so explicitly rather than emitting a bare header.
Adds the multi-turn replay coverage that existed nowhere: the outbound Bedrock
invoke body is asserted free of both block types, parametrized over the
results-present and resultless cases, and built from the interceptor's own
builder so the fixture cannot drift from what it emits.
Resolves LIT-5320
* test(websearch): pin flatten idempotency for the agentic-loop re-entry
The agentic loop re-enters the same /v1/messages entry point for its follow-up
call and hands it the original client history, so the flatten runs again over
already-flattened messages once per iteration. Bedrock always takes that path,
since its config reports web search as natively handled and the short-circuit
is skipped.
A pass that appended the rendered text instead of replacing the block would
duplicate the evidence on every iteration and re-ship the unsupported tag, and
no existing single-pass test sees it. Mutation checked: keeping the original
block alongside the rendered text fails this test on its own.

#35978 stopped the pooled A2A client replaying one upstream's Set-Cookie to
another by installing a blocking policy on that client's httpx cookie jar. That
covers only one of the two jars on the request path. AiohttpTransport is the
default transport unless it is explicitly disabled, and the aiohttp ClientSession
behind it keeps its own cookie jar which no httpx-level assertion can observe, so
the leak is still live on the default path: a live proxy on that commit still
delivers agent-alpha's session cookie to agent-beta's card fetch and JSON-RPC
call.
The reason it looked fixed is that aiohttp's default CookieJar is built with
unsafe=False and refuses to store cookies for IP hosts, so a proof addressed to
127.0.0.1 comes back clean whether or not that jar is blocked.
Cookie persistence is now blocked where the clients are built rather than at one
call site: blocked_cookie_jar() gives every httpx client, async and sync, a jar
whose DefaultCookiePolicy(allowed_domains=()) rejects every domain in both
directions, and both ClientSession constructions litellm owns, the transport's
session factory and the proxy's shared startup session, get a DummyCookieJar.
LiteLLM reads a response cookie nowhere, and an explicitly supplied Cookie header
still goes out, so passthrough forwarding and an agent's extra_headers are
unaffected. The A2A-scoped policy #35978 added is removed, since it is now dead.
The two suites that drive the aiohttp session factory synchronously mock
ClientSession because a real one needs a running event loop; DummyCookieJar has
the same requirement, so they mock it for the same reason.
Under scan_only_tool_results, legacy OpenAI function-role messages now count as tool results, and duplicate names among guardrail-returned tools keep only the first occurrence. CustomGuardrail.structured_messages_cover_full_request lets CrowdStrike AIDR declare that its writeback already rebuilds the whole conversation, so handlers install it as-is instead of merging it into the full message list a second time and duplicating out-of-scope rows. Lint budget ceilings ratchet down to match the tree
