(If it's absolutely necessary that the child process be killed, then you might want to set the death signal to SIGKILL instead of SIGTERM; the code you linked to uses SIGTERM, but the child does have the option of ignoring SIGTERM if it wants to.) + + On Windows, the most reliable options is to use a [Job object](http://msdn.microsoft.com/en-us/library/ms684161%28VS.85%29.aspx). The idea is that you create a "Job" (a kind of container for processes), then you place the child process into the Job, and you set the magic option that says "when no-one holds a 'handle' for this Job, then kill the processes that are in it". By default, the only 'handle' to the job is the one that your parent process holds, and when the parent process dies, the OS will go through and close all its handles, and then notice that this means there are no open handles for the Job. So then it kills the child, as requested. (If you have multiple child processes, you can assign them all to the same job.) [This answer](https://stackoverflow.com/a/12942797/1925449) has sample code for doing this, using the `win32api` module. That code uses `CreateProcess` to launch the child, instead of `subprocess.Popen`. The reason is that they need to get a "process handle" for the spawned child, and `CreateProcess` returns this by default. If you'd rather use `subprocess.Popen`, then here's an (untested) copy of the code from that answer, that uses `subprocess.Popen` and `OpenProcess` instead of `CreateProcess`: + + # Source - https://stackoverflow.com/a/23587108 + # Posted by Nathaniel J.

However, the thread handle for the newly-created process's initial thread is closed by the library before Popen returns. + Now, I need to create a process suspended (CREATE_SUSPENDED in creation flags) so that I can manipulate it (specifically, attach it to a job object) before it has a chance to execute any code. However, that means I need the thread handle in order to release the process from suspension (using ResumeThread). The only way I can find, to recover the thread handle, is to use the "tool help" library to walk over all threads on the entire system (e.g. see this question and answer https://stackoverflow.com/questions/9965784/how-to-obtain-list-of-thread-handles-from-a-win32-process). This works, but I do not like it. Specifically, I am concerned that taking a snapshot of all the threads on the system every time I need to create a process will be too expensive. (The larger application is a test suite, using processes for isolation; it creates and destroys processes at a rate of tens to hundreds a second.) + So, the question is: is there a more efficient way to resume execution of a process that was suspended by CREATE_SUSPENDED, if all you have is the process handle, and the facilities of the Python 2 standard library (including ctypes, but not the winapi add-on)? Vista-and-higher techniques are acceptable, but XP compatibility is preferred. + + _ + I have found a faster approach; unfortunately it relies on an undocumented API, NtResumeProcess.

They are used by a handful of core system DLLs and EXEs all of which, AFAICT, are part of the Windows Error Reporting mechanism (faultrep.dll, werui.dll, werfault.exe, dwwin.exe, etc) and don't appear to re-expose the functionality under documented names. It seems unlikely that these functions would change their semantics without also changing their names, but a defensively-coded program should probably be prepared for them to disappear (falling back to toolhelp, I suppose). + + _________________________ + + https://stackoverflow.com/questions/9965784/how-to-obtain-list-of-thread-handles-from-a-win32-process + How to obtain list of thread handles from a win32 process? + Just be aware that OpenThread returns an alternate HANDLE, not the original HANDLE.
