execution

问题 I debugged my java code. It didn't give any errors.But when i executed it (it isn't giving errors either, but) the code didn't successfully terminate. This is very funny. But is that even possible? 回答1: sure, when the slowdown introduced by debugger does mask some race condition, but this normally only applies to multi-threading or networking code. 回答2: Yes it is possible that code works when debugging and doesn't work when running. Two possible reasons I can think of right now are

问题 I have php file which consist of curl code so as to access an api. But when I upload this file on server and try to execute it via url no output is shown. Also file symbol is not shown as it is shown for php file. Guide me how to solve this problem. The code in php file is : <?php // set up the curl resource $ch = curl_init(); curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json')); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch,CURLOPT_POSTFIELDS,"{}"); curl

问题 I have an Azure function which is triggered by changes in the blob. [FunctionName("...")] public static void Run([BlobTrigger("...", Connection = "")]Stream myBlob, string name, ILogger log) { var processor = new ProcessBusiness(....); processor.CallA(); CallB(); } There is a function called CallA() In that function, I make a call to a stored procedure which takes a lot of time to execute and I expect the function CallB() to be executed when CallA() finishes. But it does not behave like this.

问题 I have a script that I need to bump out of the javascript execution queue. I have found that I can do this with a couple methods. alert();//of course we can't use this one. setTimeout(function(){ someScript();//works, but are there vulnerabilites? }, 1); What other methods are there and what is the correct way to bump out of the javascript execution queue? If setTimeout is the best option, what are the vulnerabilities of using setTimeout? Are there possible future problems, possibility that

问题 I need to execute multiple functions one after another in fixed time intervals, thus using setTimeout. I want to ensure that I understand how it executes. I have following logic: setTimeout(function() { //Execute first function }, 200); setTimeout(function() { //Execute second function }, 400); setTimeout(function() { //Execute third function }, 600); Does this mean that first function executes after 200ms, second one 200ms after the first, and the third one 200ms after the second and so on?

问题 I have tracing meta-interpreter made from my previous questions here and I would like to make similar meta-interpreter but this time for making execution trees. I've made something like this below using similar to same code found on the web and techniques from my previous questions. clause_tree(true,_,true) :- !, true. clause_tree((G,R),Trail,(TG,TR)) :- !, clause_tree(G,Trail,TG), clause_tree(R,Trail,TR). clause_tree(G,_,prolog(G)) :- (predicate_property(G,built_in) ; predicate_property(G

问题 I have code that looks something like this: function pathfind (start,end,map) { this.Init = function () { this.open_node = new Array(); this.open_node.push(start); console.log(this.open_node); this.Loop(); } this.Loop = function () { //Some code here } this.Init(); } For some reason when I push "start" to this.open_node and I log its value, I get "undefined". However, after some bug testing I realized that commenting out this.Loop(); in this.Init causes push to function properly and console

问题 I have this code that downloads a web page: HttpURLConnection connection; private String downloadContent() { InputStream content; Source parser; try { content = connection.getInputStream(); //<--here is the download parser = new Source(content); content.close(); return parser.toString(); } catch (Exception e) { return null; } } While doing the download, I tried to get the amount of downloaded data, and if it reaches a limit, I stop the downloading, but I not found a way to do this. If someone

问题 I'm trying to define a base class ( SubStatus ) for an Enum. When are the static blocks called below? If they were classes rather than enums I believe they would be called after the class constructor is called? But because they are Enum s, aren't these more like static classes to begin with? So perhaps the static blocks are execute when the container is loading the static instances? SubStatus public enum SubStatus { WAITING(0), READY(1); protected static final Map<Integer,SubStatus> lookup =

问题 I don't think this is currently possible or if it's even a good idea, but it's something I was thinking about just now. I use MSTest for unit testing my C# project. In one of my tests, I do the following: MyClass instance; try { instance = getValue(); } catch (MyException ex) { Assert.Fail("Caught MyException"); } instance.doStuff(); // Use of unassigned local variable 'instance' To make this code compile, I have to assign a value to instance either at its declaration or in the catch block.
