connects. Such properties can be used directly inlaunchconfiguration, but must be set in this manner forattachconfigurations. For example, if you don't want the debug server to automatically inject itself into subprocesses created by the process you're attaching to, use--configure-subProcess ...

Super easy to use, no source code change for most features, no package dependency Low overhead, probably the fastest tracer in the market Supports threading, multiprocessing, subprocess, async and PyTorch Powerful front-end, able to render GB-level trace smoothly ...
Select OK to save the changes. Debug the program launcher When you use this method, you can't debug the py.exe program launcher because it spawns a child python.exe subprocess. The debugger doesn't attach to the subprocess. For this scenario, the workaround is to launch the python.ex...
IO(input/output)即数据的读取和写入,用户进程的一个完成IO分为两阶段:用户进程空间<->内核空间,内核空间<->设备空间(磁盘,网络),IO有内存IO,网络IO,磁盘IO三种,一般指后两种 linux进程无法直接操作IO设备,需要通过系统调用请求kernel来协助完成IO动作,内核为每一个IO设备维护一个缓冲区,对于一个输入操作,进程IO...
