llama.cpp Release b9656 Hardens PEG Tool Call Parsing and Error Handling
English summary
llama.cpp release b9656 hardens the PEG-native tool call parsing. It now accepts an optional leading "type":"function" field to accommodate OpenAI-style tool call serialization. On a final parse failure, the parser returns a clean error and logs the unparsed fragment instead of throwing raw internal state. The raw arguments string is preserved when it is not valid JSON, preventing an abort of the prompt rendering. Parse failures are surfaced with clearer error messages, eliminating silent empty assistant turns. The lenient handling of the "type":"function" field is gated behind an analysis flag.
Chinese summary
llama.cpp b9656 版本强化了 PEG 原生工具调用解析。现在可接受可选的 "type":"function" 字段，以兼容 OpenAI 风格的工具调用序列化。最终解析失败时，解析器返回清晰的错误并记录未解析的片段，而非抛出原始内部状态。当 raw arguments 不是合法 JSON 时会保留原始字符串，避免中断提示渲染。解析失败会以更清晰的错误消息呈现，消除静默的空 assistant 回合。对 "type":"function" 字段的宽松解析受分析标志控制。
