问题 1. Problem explained I need to run the merge tool (part of the GNU RCS project - Revision Control System) on Windows 10. These are the requirements: STEP 1: The executable merge.exe must run in a native Windows cmd terminal. STEP 2: The PATH env variable should not be modified. STEP 3: The executable can be located in any arbitrary folder (of course, it's okay to put a bunch of dll's next to it if required). It would lead us too far to explain why these requirements are so important. Please,

问题 It seems that a successful test of the existence of a windows named pipe by using os.path.exists() prevents the pipe from working. Why would this be? Here is successfully working windows named-pipe code: import time import multiprocessing as mp import win32pipe, win32file PIPENAME = r'\\.\pipe\Foo' def producer(pipe_name: str): print('producer') # if not os.path.exists(pipe_name): # print(f'No pipe {pipe_name}') # return pipe = win32file.CreateFile(pipe_name, win32file.GENERIC_READ |
