termination

问题 I'm trying to formalize each integer as an equivalence class of pairs of natural numbers, where the first component is the positive part, and the second component is the negative part. Definition integer : Type := prod nat nat. I want to define a normalization function where positives and negatives cancel as much as possible. Fixpoint normalize (i : integer) : integer := let (a, b) := i in match a with | 0 => (0, b) | S a' => match b with | 0 => (S a', 0) | S b' => normalize (a', b') end end.

问题 This question already has answers here : How to get a null terminated string from a C# string? (4 answers) Closed 2 years ago . Hello StackOverflowers, I read somewhere that C# string are not null terminated. M'fine ! But I'd like to know if the method : byte[] myBytes = Encoding.ASCII.GetBytes(myString); add a null termination character to the end of the array or if I must do it manually ? (the C system which will use this array does need it). If manual, I guess the way would be : byte[]

问题 Suppose I have a Java application that opens a database connection. Normally I would add a connection.close() in a finally block, but this block wouldn't be executed in the case of a kill operation, or any other abnormal termination, would it? Are there any other precautions that I, as a programmer, can make in order to close the connection properly before the application exits? 回答1: You should look at the Runtime.addShutdownHook() method for Java (http://java.sun.com/javase/6/docs/api/java

问题 I am attempting to have a kubernetes nginx deployment with zero downtime. Part of that process has been to initiate a rollingUpdate, which ensures that at least one pod is running nginx at all times. This works perfectly well. I am running into errors when the old nginx pod is terminating. According to the kubernetes docs on termination, kubernetes will: remove the pod from the endpoints list for the service, so it is not receiving any new traffic when termination begins invoke a pre-stop

问题 Say we have a call-back timer function call_time(obj, event). I want to know the elapsed time (delt_time) during the execution of timer function once it is started. Furthermore, I want to use that elapsed time to decide if the function will be continued executing or be terminated (say delt_time > 60s). I want the timer function to determine the running time concurrently. By doing this way, the code knows when to terminate the program once it reaches to the threshold. Actually, I have asked a
