* test: drop the cwd-relative sys.path.insert calls from the test suite
TQ003 stands at 1,077 across 1,058 files, and 1,015 of them are the same shape:
sys.path.insert(0, os.path.abspath("../..")) and its deeper siblings. The
argument resolves against the working directory rather than the file, so from
the repo root, where every job runs pytest, it inserts the directory two levels
above the checkout. It has never pointed at litellm. The package is installed
into the environment anyway, which is what actually makes the import work, and
what the rule's message has said all along.
Removing them leaves 1,634 imports of sys and os with no remaining reference,
and those go too, except where another test module imports the name back out of
the file. The rest of TQ003 is 62 call sites that resolve against __file__ or a
variable, which are a different question and are left alone.
Collection is identical either way: 45,871 tests and the same 51 pre-existing
collection errors before and after, and ruff reports no new undefined name.
* test: drop the duplicate imports the sys.path sweep exposed to F811
* test(pre-call-utils): restore the os import the new bedrock tests need
* feat(github_copilot): route /v1/messages to Copilot native Anthropic endpoint
Add a GitHub Copilot Anthropic Messages transformation that routes supported Claude models through the native /v1/messages endpoint. This covers request URL construction, default headers, and supported model metadata.
* fix(github_copilot): address PR review feedback
Tighten the Anthropic Messages environment validation and web search interception behavior after review feedback. Avoid treating non-web-search requests as web-search-only paths.
* style(github_copilot): apply black formatting
Apply Black formatting to the GitHub Copilot Anthropic Messages tests.
* test(github_copilot): cover ProviderConfigManager dispatch for Anthropic Messages
Add coverage for ProviderConfigManager dispatch when GitHub Copilot models use the Anthropic Messages API, including non-Anthropic models returning no config.
* fix(github_copilot): apply messages-proxy intent header to /v1/messages
Set the messages-proxy interaction header for GitHub Copilot Anthropic Messages requests so /v1/messages uses the expected Copilot intent.
* fix(github_copilot): use modern generic annotations
Replace legacy typing generics in the GitHub Copilot Anthropic Messages transformation so the strict Ruff budget gate stays within its ceiling.
* refactor(github_copilot): decouple web-search short-circuit and harden /v1/messages URL
Address review feedback on the Copilot native Anthropic messages path.
Replace the hardcoded LlmProviders.GITHUB_COPILOT check in the web-search
interception handler with a handles_web_search_natively() method on
BaseAnthropicMessagesConfig (default True), overridden to False in
GithubCopilotAnthropicMessagesConfig. Provider-specific behavior now lives in
llms/ and the handler stays provider-agnostic, so a future provider in the same
situation needs no carve-out here.
In get_complete_url, reuse the already-resolved api_base returned by
validate_anthropic_messages_environment instead of reading the authenticator a
second time, removing redundant I/O and the mid-request inconsistency window.
The caller-supplied base is still discarded in validate, which is the security
boundary. Normalize a trailing slash on the base in both methods so a
tenant-specific host never yields a double-slash //v1/messages URL.
* fix(github_copilot): forward anthropic-beta headers on /v1/messages
The Copilot config inherited should_filter_anthropic_beta_headers()==True
from BaseAnthropicMessagesConfig, so update_headers_with_filtered_beta
stripped every anthropic-beta value after validate_anthropic_messages_environment
injected them (github_copilot has no mapping in
anthropic_beta_headers_config.json). That silently disabled header-gated
features like context_management and structured outputs on the native
passthrough. Override the hook to False, matching OpenAILikeAnthropicMessagesConfig.
* test(github_copilot): remove dead branch in beta-header regression test
The anthropic-beta filtering test guarded the fix with an if branch on
should_filter_anthropic_beta_headers(), which is always False, so the branch was
unreachable. Replace it with a direct assertion that running the provider-scoped
filter for github_copilot strips every beta value, proving why the override is
load-bearing and catching a regression that flips it back on.
