Copilot 4ec09cb611 Centralize proxy HTTP client creation in aiutil and remove redundant backend tests (#2961) ... `makeHTTPClient(proxyURL)` had been duplicated across AI backends with equivalent behavior. This change consolidates the logic into a single helper in `aiutil` and updates backends to consume it, then removes backend-local tests that only re-verified that shared utility behavior. - **Shared client construction** - Added `aiutil.MakeHTTPClient(proxyURL string) (*http.Client, error)` in `pkg/aiusechat/aiutil/aiutil.go`. - Standardizes proxy parsing and `http.Transport.Proxy` setup in one place. - Keeps streaming-safe client semantics (`Timeout: 0`) and existing invalid proxy URL error behavior. - **Backend refactor** - Removed duplicated client/proxy setup blocks from: - `pkg/aiusechat/openaichat/openaichat-backend.go` - `pkg/aiusechat/gemini/gemini-backend.go` - `pkg/aiusechat/openai/openai-backend.go` - `pkg/aiusechat/anthropic/anthropic-backend.go` - Replaced with direct calls to the shared helper. - **Test cleanup** - Deleted backend tests that only covered basic proxy client creation and no backend-specific behavior: - `pkg/aiusechat/openaichat/openaichat-backend_test.go` - `pkg/aiusechat/gemini/gemini-backend_test.go` ```go httpClient, err := aiutil.MakeHTTPClient(chatOpts.Config.ProxyURL) if err != nil { return nil, nil, nil, err } resp, err := httpClient.Do(req) ``` <!-- START COPILOT CODING AGENT TIPS --> --- 💬 We'd love your input!
