Honcho Python SDK 迁移（v1.6.0 → v2.1.1）

概述

此技能可将代码从 honcho Python SDK v1.6.0 迁移到 v2.1.1（Honcho 3.0.0+ 必需）。

主要破坏性变更：

• 移除 AsyncHoncho/AsyncPeer/AsyncSession → 改用 .aio 访问器
• 术语从“Observation”改为“Conclusion”
• 移除 Representation 类（现在返回 str）
• get_config/set_config → get_configuration/set_configuration
• 使用 chat_stream() 进行流式传输，而非 chat(stream=True)
• 移除 poll_deriver_status()
• 移除 .core 属性

快速迁移

1. 更新异步架构

# Before
from honcho import AsyncHoncho, AsyncPeer, AsyncSession

async_client = AsyncHoncho()
peer = await async_client.peer("user-123")
response = await peer.chat("query")

# After
from honcho import Honcho

client = Honcho()
peer = await client.aio.peer("user-123")
response = await peer.aio.chat("query")

# Async iteration
async for p in client.aio.peers():
    print(p.id)

2. 将 observations 替换为 conclusions

# Before
from honcho import Observation, ObservationScope, AsyncObservationScope

scope = peer.observations
scope = peer.observations_of("other-peer")
rep = scope.get_representation()

# After
from honcho import Conclusion, ConclusionScope, ConclusionScopeAio

scope = peer.conclusions
scope = peer.conclusions_of("other-peer")
rep = scope.representation()  # Returns str

3. 更新 representation 处理方式

# Before
from honcho import Representation, ExplicitObservation, DeductiveObservation

rep: Representation = peer.working_rep()
print(rep.explicit)
print(rep.deductive)
if rep.is_empty():
    print("No observations")

# After
rep: str = peer.representation()
print(rep)  # Just a string now
if not rep:
    print("No conclusions")

4. 重命名配置方法

# Before
config = peer.get_config()
peer.set_config({"observe_me": False})
session.get_config()
client.get_config()

# After
from honcho.api_types import PeerConfig, SessionConfiguration, WorkspaceConfiguration

config = peer.get_configuration()
peer.set_configuration(PeerConfig(observe_me=False))
session.get_configuration()
client.get_configuration()

5. 更新方法名称

# Before
peer.working_rep()
peer.get_context()
peer.get_sessions()
session.get_context()
session.get_summaries()
session.get_messages()
session.get_peers()
session.get_peer_config()
client.get_peers()
client.get_sessions()
client.get_workspaces()

# After
peer.representation()
peer.context()
peer.sessions()
session.context()
session.summaries()
session.messages()
session.peers()
session.get_peer_configuration()
client.peers()
client.sessions()
client.workspaces()

6. 更新流式传输

# Before
response = peer.chat("query", stream=True)
for chunk in response:
    print(chunk, end="")

# After
stream = peer.chat_stream("query")
for chunk in stream:
    print(chunk, end="")

7. 更新队列状态（原名为 deriver）

# Before
from honcho_core.types import DeriverStatus

status = client.get_deriver_status()
status = client.poll_deriver_status(timeout=300.0)  # Removed!

# After
from honcho.api_types import QueueStatusResponse

status = client.queue_status()
# poll_deriver_status removed - implement polling manually if needed

8. 更新 representation 参数

# Before
rep = peer.working_rep(
    include_most_derived=True,
    max_observations=50
)

# After
rep = peer.representation(
    include_most_frequent=True,
    max_conclusions=50
)

9. 将 update_message 移至 session

# Before
updated = client.update_message(message=msg, metadata={"key": "value"}, session="sess-id")

# After
updated = session.update_message(message=msg, metadata={"key": "value"})

10. 更新 card() 返回类型和方法名称

# Before
card: str = peer.card()  # Returns str

# After (v2.0.0+)
card: list[str] | None = peer.get_card()  # Returns list[str] | None
if card:
    print("\n".join(card))

# peer.card() still works but is deprecated — use get_card()

# New in v2.0.1: set_card()
peer.set_card(["Prefers dark mode", "Located in US"])

11. 严格输入验证（v2.0.2+）

现在，所有输入模型都会通过 Pydantic 验证，以 extra="forbid" 拒绝未知字段。此前，拼写错误或多余的字段会被静默忽略。

# Before (v2.0.1 and earlier) — silently ignored
peer = client.peer("user-1", configuration=PeerConfig(observe_mee=True))  # typo silently ignored

# After (v2.0.2+) — raises ValidationError
peer = client.peer("user-1", configuration=PeerConfig(observe_mee=True))  # ValidationError!

12. peer() 和 session() 始终会发起 API 调用（v2.1.0+）

破坏性变更：peer() 和 session() 现在始终会发起获取或创建 API 调用。此前，不带元数据或配置调用时，会返回不会发起 API 调用的延迟对象。

# Before (v2.0.x) — no API call without options
peer = client.peer("user-123")  # Lazy, no network request

# After (v2.1.0+) — always hits the API
peer = client.peer("user-123")  # Makes POST to /peers (get-or-create)

# Async
peer = await client.aio.peer("user-123")  # Also always hits API

13. 新属性和方法（v2.1.0+）

# created_at on Peer and Session
peer = client.peer("user-123")
print(peer.created_at)  # datetime | None

session = client.session("sess-1")
print(session.created_at)  # datetime | None

# is_active on Session
print(session.is_active)  # bool | None

# get_message() on Session
msg = session.get_message("msg-id")
# Async: msg = await session.aio.get_message("msg-id")

14. 列表方法的分页参数（v2.1.0+）

现在所有列表方法都接受 page、size 和 reverse 参数：

# Before (v2.0.x) — only filters
peers_page = client.peers(filters={"metadata": {"role": "admin"}})

# After (v2.1.0+) — pagination controls
peers_page = client.peers(
    filters={"metadata": {"role": "admin"}},
    page=2,
    size=25,
    reverse=True
)

# Works on: client.peers(), client.sessions(), peer.sessions(),
# session.messages(), scope.list()

15. 扩大 HTTP 重试范围（v2.1.1+）

现在 SDK 会在遇到 httpx.TimeoutException、httpx.NetworkError 和 httpx.RemoteProtocolError 时重试（此前只会在遇到 httpx.TimeoutException 和 httpx.ConnectError 时重试）。这些异常分别映射为 SDK 的 TimeoutError 和 ConnectionError。无需更改代码——此行为会自动生效。
