From 3704dae342760fda2d1c0aa2f260830ce861e935 Mon Sep 17 00:00:00 2001 From: Luis Pater Date: Thu, 28 Aug 2025 02:47:15 +0800 Subject: [PATCH] Add nil-check for `GetRequestMutex` across handlers to prevent potential panics - Updated all handlers to safely unlock the request mutex only if it's non-nil. - Enhanced mutex locking and unlocking logic to avoid runtime errors. - Improved robustness of resource cleanup across clients. Add `GetRequestMutex` method for synchronization across clients - Introduced a new `GetRequestMutex` method in OpenAICompatibilityClient, CodexClient, GeminiCLIClient, GeminiClient, and QwenClient for request synchronization. - Ensures only one request is processed at a time to manage quotas effectively. --- internal/api/handlers/claude/code_handlers.go | 4 +++- .../api/handlers/gemini/gemini-cli_handlers.go | 8 ++++++-- internal/api/handlers/gemini/gemini_handlers.go | 12 +++++++++--- internal/api/handlers/handlers.go | 16 +++++++++++----- internal/api/handlers/openai/openai_handlers.go | 16 ++++++++++++---- internal/client/claude_client.go | 9 +++++++++ internal/client/codex_client.go | 9 +++++++++ internal/client/gemini-cli_client.go | 9 +++++++++ internal/client/gemini_client.go | 9 +++++++++ internal/client/openai-compatibility_client.go | 9 +++++++++ internal/client/qwen_client.go | 9 +++++++++ 11 files changed, 95 insertions(+), 15 deletions(-) diff --git a/internal/api/handlers/claude/code_handlers.go b/internal/api/handlers/claude/code_handlers.go index d1e4eaeb..bbafdd47 100644 --- a/internal/api/handlers/claude/code_handlers.go +++ b/internal/api/handlers/claude/code_handlers.go @@ -133,7 +133,9 @@ func (h *ClaudeCodeAPIHandler) handleStreamingResponse(c *gin.Context, rawJSON [ // Ensure the client's mutex is unlocked on function exit. // This prevents deadlocks and ensures proper resource cleanup if cliClient != nil { - cliClient.GetRequestMutex().Unlock() + if mutex := cliClient.GetRequestMutex();
