  • How does C++ free the memory when a constructor throws an exception and a custom new is used

    - by Joshua
    I see the following constructs: new X will free the memory if X constructor throws. operator new() can be overloaded. The canonical definition of an operator new overload is void *operator new(heap h) and the corrisponding operator delete. The most common operator new overload is pacement new, which is void *operator new(void *p) { return p; } You almost always cannot call delete on the pointer given to placement new. This leads to a single question. How is memory cleaned up when X constructor throws and an overloaded new is used?

  • Very simple code for number search gives me infinite loop

    - by Joshua
    Hello, I am a newbie Computer Science high school student and I have trouble with a small snippet of code. Basically, my code should perform a basic CLI search in an array of integers. However, what happens is I get what appears to be an infinite loop (BlueJ, the compiler I'm using, gets stuck and I have to reset the machine). I have set break points but I still don't quite get the problem...(I don't even understand most of the things that it tells me) Here's the offending code (assume that "ArrayUtil" works, because it does): import java.util.Scanner; public class intSearch { public static void main(String[] args) { search(); } public static void search() { int[] randomArray = ArrayUtil.randomIntArray(20, 100); Scanner searchInput = new Scanner(System.in); int searchInt = searchInput.nextInt(); if (findNumber(randomArray, searchInt) == -1) { System.out.println("Error"); }else System.out.println("Searched Number: " + findNumber(randomArray, searchInt)); } private static int findNumber(int[] searchedArray, int searchTerm) { for (int i = 0; searchedArray[i] == searchTerm && i < searchedArray.length; i++) { return i; } return -1; } } This has been bugging me for some time now...please help me identify the problem!

  • Does IE completely ignore cache control headers for AJAX requests?

    - by Joshua Hayworth
    Hello there, I've got, what I would consider, a simple test web site. A single page with a single button. Here is a copy of the source I'm working with if you would like to download it and play with it. When that button is clicked, it creates a JavaScript timer that executes once a second. When the timer function is executed, An AJAX call is made to retrieve a text value. That text value is then placed into the DOM. What's my problem? IE Caching. Crack open Task Manager and watch what happens to the iexplorer.exe process (IE 8.0.7600.16385 for me) while the timer in that page is executing. See the memory and handle count getting larger? Why is that happening when, by all accounts, I have caching turned off. I've got the jQuery cache option set to false in $.ajaxSetup. I've got the CacheControl header set to no-cache and no-store. The Expires header is set to DateTime.Now.AddDays(-1). The headers are set in both the page code-behind as well as the HTTP Handler's response. Anybody got any ideas as to how I could prevent IE from caching the results of the AJAX call? Here is what the iexplorer.exe process looks like in ProcessMonitor. I believe that the activity shown in this picture is exactly what I'm attempting to prevent.

  • PHP debugging or performance Hook

    - by Joshua
    In an interpreted language like PHP it is possible in theory to set up some sort of callback function that would be run indiscriminately after every line of code. I am wondering if such a thing exists in PHP or if such a thing could be accomplished in any way? Such a feature could be useful for diagnostics or performance tests. Does anyone know of such a mechanism in PHP?

  • Why isn't the new() generic constraint satisfied by a class with optional parameters in the construc

    - by Joshua Flanagan
    The following code fails to compile, producing a "Widget must be a non-abstract type with a public parameterless constructor" error. I would think that the compiler has all of the information it needs. Is this a bug? An oversight? Or is there some scenario where this would not be valid? public class Factory<T> where T : new() { public T Build() { return new T(); } } public class Widget { public Widget(string name = "foo") { Name = name; } public string Name { get; set; } } public class Program { public static void Main() { var widget = new Widget(); // this is valid var factory = new Factory<Widget>(); // compiler error } }

  • cakephp htaccess for production install

    - by Joshua Foxworth
    So, I have cakephp installed in what I believed to be the appropriate way for production code with actual cake files above the public_html folder. The app folder is removed from the cake folder and placed at the same level. Loading the home page works fine with the databases and the debug working. However, in trying to run some test files I get a 404. Obviously, I need some way to direct something like www.example.com/posts/index to the proper location. I am not sure as to why this is necessary since the index.php file tells cake where the app directory is located? Also, if I need to use the .htaccess file, how do I point to the proper location and exactly what am I pointed at?

  • Libboost 1.38.0 on Ubuntu 11.04 Natty

    - by scjosh
    I have a Linux/Ubuntu DLL that depends on libboost_thread-mt.so.1.38.0 (As shown in the picture below). I've tried various ways including building my own version of LibBoost 1.38.0 yet none of my methods have worked. I was wondering if 1.38.0 is available precompiled on earlier versions of Ubuntu or if my architecture (64 Bit) is not compatible with LibBoost. Any pointers on how to fix this error are greatly appreciated. http://joshua-ferrara.com/imgoid/images/1332518188.png Best Regards, Josh

  • Why C++ is an abomination [closed]

    - by Chander Shivdasani
    Possible Duplicate: Why do so many people dislike C++? I was reading the blog by Peter Seibel (Author of Coders at Work) where brilliant programmers like Ken Thompson, Joshua Bloch and Guy Steele have despised c++ to no end. What is it in C++ that people hate so much? And despite so much hate towards it, companies like Google are still using it, and some of the programmers who snubbed C++ have worked or are already working at Google. So, what is it in the language that despite so much hate from top programmers, it's still used at most of the places? I haven't really used C++ beyond academic projects, so i don't know much about the disadvantages of the language. What do programmers here think about it? --Chander

  • Get a new instance with StructureMap

    - by Aligned
    It took me too long to figure this out, so hopefully it will help you. StructureMap has way that will create a new instance of the object every time, instead of storing this in the container. I’m going to use this for the DBContext and for WCF Service references. Since the ObjectFactory is a static class, MVC will have these stored in memory without this. Credit goes to Joshua Flanagan for answering my question.[TestMethod] public void GetConcreteInstanceOf_ShouldReturn_DifferentInstance() { ObjectFactory.Initialize(registry => { // set it up so that it's new every time // use this for DBContext and service references registry.For<ISystemDataService>().Use(() => new SystemDataService()); }); ISystemDataService result = Resolver.GetConcreteInstanceOf<ISystemDataService>(); ISystemDataService result2 = Resolver.GetConcreteInstanceOf<ISystemDataService>(); Assert.AreNotSame(result, result2); }

  • What are the consequences of immutable classes with references to mutable classes?

    - by glenviewjeff
    I've recently begun adopting the best practice of designing my classes to be immutable per Effective Java [Bloch2008]. I have a series of interrelated questions about degrees of mutability and their consequences. I have run into situations where a (Java) class I implemented is only "internally immutable" because it uses references to other mutable classes. In this case, the class under development appears from the external environment to have state. Do any of the benefits (see below) of immutable classes hold true even by only "internally immutable" classes? Is there an accepted term for the aforementioned "internal mutability"? Wikipedia's immutable object page uses the unsourced term "deep immutability" to describe an object whose references are also immutable. Is the distinction between mutability and side-effect-ness/state important? Josh Bloch lists the following benefits of immutable classes: are simple to construct, test, and use are automatically thread-safe and have no synchronization issues do not need a copy constructor do not need an implementation of clone allow hashCode to use lazy initialization, and to cache its return value do not need to be copied defensively when used as a field make good Map keys and Set elements (these objects must not change state while in the collection) have their class invariant established once upon construction, and it never needs to be checked again always have "failure atomicity" (a term used by Joshua Bloch) : if an immutable object throws an exception, it's never left in an undesirable or indeterminate state

  • Intelligence as a vector quantity

    - by Senthil Kumaran
    I am reading this wonderful book called "Coders at Work: Reflections on the Craft of Programming" by Peter Seibel and I am at part wherein the conversation is with Joshua Bloch and I found this answer which is an important point for a programmer. The paragraph, goes something like this. There's this problem, which is, programming is so much of an intellectual meritocracy and often these people are the smartest people in the organization; therefore they figure they should be allowed to make all the decisions. But merely the fact they are the smartest people in the organization does not mean that they should be making all the decisions, because intelligence is not a scalar quantity; it's a vector quantity. Here at the last sentence, I fail to get the insight which is he trying to share. Can someone explain it in a little further as what he means by a vector quantity, possibly trying to present the same insight. Further down, I get the point that he is not taking about having an organization where non-technical people (sometimes clueless) can be managers of the technical people for some reason that they can spend more time to write emails well, because the very next statement following the above paragraph was. And if you lack empathy or emotional intelligence, then you shouldn't be designing APIs or GUIs or languages. I understand that he is saying that in Software engineering, programmers should know how the users will see their product and design for them. I felt the above paragraph was very interesting.
