subprocess can't successfully restart the targeted python file

由 六月ゝ 毕业季﹏ 提交于 2019-12-08 06:35:51
问题 I write a program my_test.py to get data from web and store to mysql. But the program my_test.py collapses a lot (my bad programming skill...) and I try to monitor its status and restart it when it collapses. I use subprocess modular with the following codes. import subprocess import time p = subprocess.Popen(['python.exe', r'D:\my_test.py'], shell=True) while True: try: stopped = p.poll() except: stopped = True if stopped: p = subprocess.Popen(['python.exe', r'D:\my_test.py'], shell=True)

由 流过昼夜 提交于 2019-12-08 06:24:02
问题 After logout I need to invalidate session and start a new immediately. I used the function VaadinSession.getCurrent().getSession().invalidate(); After several seconds a red box "Session expired" appears. User must click on it or press F5. How to avoid it and to display new session page immediately? In javascript is it easy: document.location='/'; How to do the same in Vaadin? The behavior should be the same as by first visit the page after restarting explorer. 回答1: In my project I use this:

How to get an email when a computer is about to restart?

问题 My work computer usually restarts once a week over night. This is done for security purposes. I don't know in advance when this could happen. Sometimes it may take even a month until the next restart. My problem is that I have scripts running on my computer, so I would like to get a notification whenever my computer is about to restart. (I need to know when it restarts because I must log in back to my computer, otherwise the scripts won't run. Anyway . . . ) I'm trying to set Windows Task

How to auto restart a Qt application when it crashes, within the same program?

由 半腔热情 提交于 2019-12-07 07:32:11
问题 Is there any relatively "standard" design to auto restart a Qt application program, when it crashes abnormally? Specific to Windows, do I have to use any windows service? Or if I have to write another program separately, then how to do that? 回答1: Here's how you might do it using a single application that can act either as a monitor or as business logic. It's akin to Jon Harper's answer, except in code, not prose :) Of Note The monitor should not instantiate a QApplication nor QGuiApplication

How to restart an app when resumes from multi-tasking

由 笑着哭i 提交于 2019-12-06 12:29:02
问题 So my app relies on an internet connection and every time the app is opened from the home screen it checks using Reachability and then allows the user to continue or tells them to get connected. My issue however is that when the app is resumed from multitasking, it skips the initial view controller and goes straight to where they were. Is there any way in swift that I could get the app to refresh or restart when it is resumed from multi-tasking? Thanks EDIT When using this code: let

问题 I'm trying to make a vb script that will restart another vb script if it crashes. I have searched, and searched but all I get is how to restart a program and since a vb script is a background process it doesn't work when you search in Win32_Process. Here is my code set Service = GetObject ("winmgmts:") set Shell = WScript.CreateObject("WScript.Shell") sEXEName = "Test_To_Block.vbs" while true bRunning = false for each Process in Service.InstancesOf ("Win32_Process") if Process.Name = sEXEName
