Bug: 使用 --reload 加载项无法正常重新加载 #70

Closed OREOCODEDEV closed 1 year ago

OREOCODEDEV commented 1 year ago

描述问题：

使用 nb run --reload 命令启动的 NoneBot，在文件变更时无法自动重新加载，会引发 不同 的错误直接退出进程

如何复现？

  1. 使用 nb-cli 创建新NoneBot项目
  2. 使用 nb run --reload 命令启动NoneBot
  3. 在src文件夹中写入任意.py后缀文件
  4. 此时便会抛出Traceback，无法重新加载NoneBot2

由于不清楚是nb-cli的问题还是nonebot2的问题，所以先来这里开个issue了

*之前在2.0.0-beta2版本，通过.env文件中的fastapi_reload配置项设置的自动重新加载是正常的

*这个环境运行我写的一些 FastAPI 项目，使用uvicorn main:app --reload命令启动时能正常重新加载的

环境信息：

截图或日志

经过测试，每次自动重新加载抛出的Traeback位置都不完全一致，以下是观察到的几种在重新加载期间抛出的Traceback，可能不是全部的情况（不同Traceback期间项目没有任何改动）

image 我也有类似的问题，使用nb run --reload启动，修改文件后连接直接关闭了，没有报错

KotoriKoi commented 1 year ago

另外使用nb run启动后ctrl+c无法终止进程，而是重启进程，重启后gocq一直报WARNING，不知道是哪个模块的问题。

OREOCODEDEV commented 1 year ago

又看了一下，每次Traceback不一样不会是因为这个 KeyboardInterrupt 每次抛出的时间节点有一些细小的差别导致的吧，那这样的话Traceback可能参考意义不是非常大了

forchannot commented 1 year ago

同，windows服务器server2022，使用reload模式启动修改任意内容后直接卡死，等几分钟无反应 7a17670aa8c81329

yanyongyu commented 1 year ago

你这个卡死是uvicorn还没shutdown完成，不是nbcli的问题，你可以检查一下是否有代码阻塞了进程退出

forchannot commented 1 year ago

哪类代码会阻塞呢，安装的插件太多了，不好全部一一排查(破案了，playwright的问题）
