suspend

问题 While debugging my Python 3.5 pogram in Pycharm 5.0.4, I am trying to hit the pause button to find how why/where the program is hanging (as can be done in Visual Studio). However, nothing happens: the pause button does not become grey and the resume button stays grey, and in the debugger tool window, "Frames are not available". I tried with different basic programs, on Linux and on Windows, to no avail. Is this a bug or am I missing something in how Pycharm debugging is supposed to work? I

问题 I'd like to write a short python script that puts my computer to sleep. I'Ve already searched the API but the only result on suspend has to do with delayed execution. What function does the trick ? 回答1: You can run shell command from python script. See subprocess module and then search for appropriate command for your operating system. 回答2: I don't know how to sleep. But I know how to Hibernate (on Windows). Perhaps that is enough? shutdown.exe is your friend! Run it from the command prompt.

问题 Is there any possible way to protect an exe from being suspended ? Note that the i'm the owner of the application. 回答1: There are tools such as Sysinternals ProcessExpert that allows you to suspend any process. If the user has admin authorisations there is no way to avoid this. This SO answer shows three solutions to suspend a windows process. However there is a way to make this extremely difficult : the solution consist of having a shadow process for your application. The application and the

问题 I'm using Retrofit in order to make some network requests. I'm also using the Coroutines in combination with 'suspend' functions. My question is: Is there a way to improve the following code. The idea is to launch multiple requests in parallels and wait for them all to finish before continuing the function. lifecycleScope.launch { try { itemIds.forEach { itemId -> withContext(Dispatchers.IO) { itemById[itemId] = MyService.getItem(itemId) } } } catch (exception: Exception) { exception

问题 Can anyone give clarity between functions CoroutineScope() and coroutineScope() ? When I tried to check in source, I found that both of them are functions of CoroutineScope.kt . Additionally, coroutineScope() is suspend function while other one is normal function Below is documentation I could find : /** * Creates a [CoroutineScope] that wraps the given coroutine [context]. * * If the given [context] does not contain a [Job] element, then a default `Job()` is created. * This way, cancellation

问题 I have a little Bash script which suspends the computer after a given number of minutes. However, I'd like to extend it to tell me what the time will be when it will be suspended, so I can get a rough idea of how long time I have left so to speak. #!/bin/sh let SECS=$1*60 echo "Sleeping for" $1 "minutes, which is" $SECS "seconds." sleep $SECS && pm-suspend The only argument to the script will be how many minutes from now the computer should be suspended. All I want to add to this script is
