fix: 超时日志不再打空消息（诊断 Merge facts error 空行） - #23
Merged

Conversation
用户日志里出现三条 `Merge facts error:` —— 冒号后没有内容，间隔精确
30 秒（等于 _DEFAULT_LLM_CHAT_TIMEOUT）。原因是 asyncio.TimeoutError
的 str(e) 为空字符串，而这四个 handler 直接把 e 插进消息里：
logger.error(f"Merge facts error: {e}")
四个提取方法早就有 isinstance(e, asyncio.TimeoutError) 分支，但
merge_facts / _check_conflict / generate_semantic_id /
generate_reflections 没有，所以 provider 变慢时日志无法自证，看起来
像是解析失败或未知错误。
行为不变：三次超时都正常走了拼接兜底，那批 5 条 facts 完整落盘。这
里只补日志，30s 默认值和降级策略都保持原样。
非超时异常同时补上 type(e).__name__ —— 空消息异常不止 TimeoutError
一种，只打 str(e) 同样会得到裸冒号。
测试用 fake client 模拟慢响应，无网络、无 API key。两条日志断言在源码
改动单独 stash 后失败，并复现出用户看到的那行空消息；其余 8 条钉住各
路径的降级值（拼接 / "new" / "" / []），防止后续把兜底改坏。83 passed。

Estimated code review effort: 2 (简单) | ~10 minutes Merge Risk: 🟡 Moderate · up to This PR improves timeout logging while preserving existing fallback behavior, but non-timeout provider failures may still be logged without the promised operation and exception type, and subsecond timeout settings can be reported incorrectly as 0s.

| Filename | Overview |
|---|---|
| memory/llm_adapter.py | Removes generic exception swallowing so operation-specific callers can log and handle provider failures. |
| memory/memory_extractor.py | Adds explicit timeout diagnostics, exception type names, and %g formatting that correctly preserves fractional timeout values. |
| tests/test_memory_extractor.py | Adds fake-client tests covering LLM success, timeout, provider-error, and missing-client fallback paths. |

- Line 383: Update all four timeout log messages in MemoryExtractor to use a
floating-point format such as %g for self.llm_chat_timeout instead of %d,
preserving accurate values such as 0.05 seconds.
- Line 385: 调整 chat_text() 及其四个指定调用方，使 provider 的非超时异常能够传播到这四个方法的 except
分支；其他调用方继续保持异常时返回空字符串的契约。由各调用方记录包含操作名和异常类型的上下文日志，并保留超时处理逻辑。为四个调用补充非超时异常测试，断言异常传播及日志内容。
In `@tests/test_memory_extractor.py`:
- Line 35: Update _run() to retain the event loop created by
asyncio.new_event_loop(), execute the coroutine as before, and close that loop
in a finally block so cleanup occurs on both success and failure.

…, event loop leak
Addresses all three findings from code review:
1. Timeout logging precision (%d → %g)
- Changed all 8 timeout log messages from %d to %g so fractional timeouts
(e.g., 2.5s) display correctly instead of truncating to 2
- Affected: extraction (personal/group/unified), dedup, merge, reflection,
semantic ID generation, profile compaction
2. Provider error propagation and operation naming
- Removed try/except from chat_text() so provider exceptions propagate to
each operation's own handler with its operation name in the log
- Before: all 8 operations collapsed into 'chat_text failed:' with no
context; non-timeout branches in handlers were unreachable
- After: 'Personal fact extraction error:', 'Merge facts error:', etc.
with provider exception type and message
- Added 6 tests verifying each operation logs its name on provider failure
3. Event loop leak in test helpers
- Replaced asyncio.run() with asyncio.new_event_loop() + run_until_complete()
in _run() helper so each test call gets a fresh loop instead of reusing
the pytest-asyncio fixture loop and leaving it unclosed
- Prevents 'RuntimeWarning: coroutine was never awaited' and resource leaks
All 89 tests pass.

问题
用户实际日志：
冒号后面什么都没有，无法判断是超时、provider 报错还是响应解析失败。
根因
asyncio.TimeoutError的str(e)是空字符串，而这四个 handler 直接把e插进消息：四个提取方法（
extract_personal_facts等）早就有isinstance(e, asyncio.TimeoutError)分支会打出 "timed out after Ns"，但merge_facts/_check_conflict/generate_semantic_id/generate_reflections没有。日志本身其实已经能定位：三条 error 间隔精确 30 秒，正好等于
_DEFAULT_LLM_CHAT_TIMEOUT = 30.0。是超时，而且是 5 条 group facts 里有 3 条命中已有记忆需要合并，每条各自超时一次。影响面：只是质量退化，不是数据损坏
三次超时都正常走了
merge_facts的拼接兜底（f"{existing}；{new}"），末行5 facts (0 personal + 5 group)证明批次完整跑完。代价是那 3 条合并记忆变成了生硬拼接文本，而不是 LLM 改写过的句子。改动
只改日志，不改行为。 30s 默认值和各路径的降级策略全部保持原样：
TimeoutError分支，打出"... timed out after Ns; LLM provider may be slow or rate-limited"type(e).__name__—— 空消息异常不止TimeoutError一种，只打str(e)同样会得到裸冒号测试
新增
tests/test_memory_extractor.py，10 条，用 fake client 模拟慢响应。无网络、无 API key，timeout 设 0.05s 所以跑得很快（0.33s）。两条日志断言是真闸门 —— 把源码改动单独 stash 后失败，并复现出用户看到的那行空消息：
其余 8 条钉住各路径的降级值（拼接 /
"new"/""/[]），防止后续把兜底改坏 —— 这些在修复前后都通过，是刻意的。全量 83 passed。
如果超时继续出现
日志现在能自证了。看到
Merge facts timed out after 30s就说明确实是 provider 慢，届时可以考虑：调高llm_chat_timeout、给extraction_model配一个更快的模型、或者把超时改成跳过合并（保留原记忆不动）而不是拼接。这些都是行为改动，等日志确认后再单独决定。🤖 Generated with Claude Code
