fix(anthropic): count a replayed server tool call's cache mark the way modify_params sends it (#46591)
* fix(anthropic): count a replayed server tool call's cache mark the way modify_params sends it

With modify_params on, a trailing tool search turn whose call has a kept result
got a placeholder answer from the factory and went out as a marked tool_use,
but the cache control hook counted marks before that placeholder existed and
skipped the mark, so a request at the cap reached Anthropic with 5 marks and
failed with a 400. The hook now finds client answers on the sanitized messages,
the same list the factory reads.

Also make the replay checks cheaper (prefix check before validation, early
return without provider_specific_fields, and look up client answers only when
a tool call carries cache_control), drop the two audit cells that cover old
gaps outside the tool search fix, and derive the pass-through test timeout
from the graceful stop budget.

* fix(anthropic): keep the duplicate tool result warning out of the cache control hook

The hook finds client answers with only the step of the modify_params sanitize
pass that pairs tool calls with their results, so a request with a duplicate
tool result logs the warning once again instead of once per mark count.

Also restore the Snowflake non-stream and cached-stream tool search cells as
known bugs with pytest.skip instead of deleting them, and put the Anthropic
pass-through test timeout back to 240 seconds.

* fix(anthropic): count cache marks next to a message the pairing step cannot read

With modify_params on and a marked tool call, the cache control hook paired tool
calls with their results before counting. A message without a get method (a
stray string or null in extra_body.messages, or an openai SDK
ChatCompletionMessage) made that pairing raise AttributeError before any
provider call, where main counted the marks and let the request through.

The hook now pairs only when every message can be read the way the pairing
step reads it, and otherwise counts on the messages as sent, like main did.

* fix(anthropic): count cache marks after placing a later system message the way the request builder does

* test(anthropic): cover a leading system prompt and a system message before the answer in the cache mark census

* test(anthropic): align the tool search replay cells with main and cover a system message after the search turn

The malformed kept result cells now expect the unanswered search call to be dropped, as main does since #45882.
The stream cut cell checks streamed tool call names, since the kept search result names get_weather as a tool
reference. The streamed response cache hit cell runs again because #46104 fixed it. The modify_params cap cell
expects the four client marks, since the placeholder answer sends the search call as a plain tool_use with its
mark, and a new cell covers a system message after the trailing search turn in both stream modes

* fix(anthropic): count marks on the raw messages when they cannot be placed, and find client answers once per request

* test(anthropic): cover marked tool calls next to a malformed tool id and a later system message

* perf(anthropic): look up client tool answers only when a marked tool call is a server tool call

Answered ids only decide whether a marked srvtoolu_ call is rebuilt as server_tool_use, so a request whose marked
tool calls are all client calls no longer places system messages or runs the modify_params pairing step to count
marks

* test(anthropic): reach the client answer lookup with a marked search call in the malformed tool id cell

* perf(anthropic): place mid-conversation system messages in linear time for models that keep them

* fix(anthropic): count cache marks with the model's own system message placement and pair tool results in linear time

* test(anthropic): cover modify_params dropping a tool answer that answers no call of the latest assistant turn

* fix(anthropic): count marks with in-place system placement when the model lookup cannot confirm the flag

* test(anthropic): cover a bare model with custom_llm_provider filling the cache mark budget through litellm.completion and Router

* fix(anthropic): give unmapped models the request builder's converting placement and survive any model lookup failure

* test(anthropic): cover an unmapped model name counting cache marks with the request builder's converting placement

* fix(anthropic): count server tool call cache marks the request builder's way only on routes that build Anthropic Messages requests

Databricks, OpenRouter and Bedrock Converse send every marked tool call as is, so the hook keeps the census main uses there. The seeding step carries custom_llm_provider on the injection points when a server tool call is marked, so a bare model name still resolves its route.

* test(anthropic): cover two answered marked server tool calls before a system message on Databricks, OpenRouter and Bedrock Converse

* fix(anthropic): keep main's cache mark count on GitHub Copilot and ChatGPT routes without resolving them, so a sync call with no stored login never starts the device flow

* test(anthropic): cover a marked server tool call reaching the GitHub Copilot and ChatGPT login hosts like an unmarked one

In total litellm runs 1000+ tests

[02/20/2025] Update:

To make it easier to contribute and map what behavior is tested,

we've started mapping the litellm directory in tests/unit

This folder can only run mock tests.
