731,213 | 0 | <p>You are coupling classes too tightly and mixing values and references. You should either consider checking reference equality for one of the classes or make them aware of each other (by providing an <code>internal</code> specialized <code>Equals</code> method for the specific class or manually checking value equality of the other class). This shouldn't be a big deal since your requirements explicitly ask for this coupling so you are not introducing one by doing this.</p> |

32,878,450 | 0 | node.js - infinite loop during JSONStream <p>I've got a node.js server that is freezing in production, and it appears to be caused by an infinite loop inside of JSONStream. Here's a stack trace captured from a core dump from a frozen server:</p> <pre><code>1: toString [buffer.js:~392] (this=0x1e28fb6d25c9 <a Buffer>#1#,encoding=0x266ee104121 <undefined>,start=0x266ee104121 <undefined>,end=0x266ee104121 <undefined>) 2: arguments adaptor frame: 0->3 3: write [/home/deploy/node_modules/JSONStream/node_modules/jsonparse/jsonparse.js:136] (this=0x32cc8dd5a999 <a Parser>#2#,buffer=0x32cc8dd5aa49 <a Buffer>#3#) 4: /* anonymous */ [/home/deploy/node_modules/JSONStream/index.js:~17] (this=0x32cc8dd5ab11 <a Stream>#4#,chunk=0x32cc8dd5aa49 <a Buffer>#3#) 5: write [/home/deploy/node_modules/JSONStream/node_modules/through/index.js:~24] (this=0x32cc8dd5ab11 <a Stream>#4#,data=0x32cc8dd5aa49 <a Buffer>#3#) 6: write [_stream_readable.js:~582] (this=0x266ee106c91 <JS Global Object>#5#,dest=0x32cc8dd5ab11 <a Stream>#4#,i=0,list=0x266ee104101 <null>) 7: flow [_stream_readable.js:592] (this=0x266ee106c91 <JS Global Object>#5#,src=0x32cc8dd5ac69 <an IncomingMessage>#6#) 8: /* anonymous */ [_stream_readable.js:560] (this=0x266ee106c91 <JS Global Object>#5#) 9: _tickCallback [node.js:415] (this=0x29e7331bb2a1 <a process>#7#) </code></pre> <p>How can I find the source of this infinite loop?</p> <p>Unfortunately the servers are running in production and are processing many thousands of requests, so it's difficult to give any additional context. The basic function of the servers is to make outbound HTTP requests for other services.</p> <p>It's worth noting that I don't believe this is caused by a memory leak. The server's memory usage remains constant (and low) during these freeze events, while the CPU spikes to 99%</p> <p>Another piece of evidence towards the conclusion of an infinite loop is that the event loop itself seems to have stopped. When I put a console.log inside of a setInterval, the server will stop outputting as soon as it freezes.</p> <p>We have verified that the problem is not caused by expired/corrupted socket connections, by setting the number of max connections to Infinity (which disables their reuse in node.js)</p> <p>We're using JSONStream 0.7.1 (which includes a default jsonparse version of 0.0.5). We found <a href="https://github.com/creationix/jsonparse/pull/22" rel="nofollow">this issue</a> on the JSONStream repo, and tried forking JSONParse and only updating to the newest jsonparse version. It did NOT fix the issue.</p> |
29,430,890 | 0 | <p>IMHO there are three reasonable scenarios for <code>Optional</code>:</p> <ul> <li>Do something if there is a value</li> <li>Provide a default value otherwise</li> <li>The absence of a value is an error condition, in which case you want to fail fast</li> </ul> <p>Your scenario falls into the last category so I would simply write:</p> <pre><code> MyDao oq = myOptional.orElseThrow(() -> new RuntimeException("Entity was not found"); if(!oq.getReferenceId().equals(objToUpdate.getId())) throw new RuntimeException("Bad Move!"); oq.setAttribute(objToUpdate.getAttribute()); </code></pre> <p>Of course, it's appealing to use methods like <code>ifPresent</code>, <code>filter</code> or <code>map</code>, but in your case, why would you want to continue when the application is in a faulty state. Now if you wouldn't throw an exception if the entity wasn't found, then the situation would be different.</p> <p>Something like <code>oq.checkMove(objToUpdate.getId())</code> could make sense. That would eliminate the <code>if</code> and make the code more expressive.</p> |

If the binding does not support security (such as BasicHttpBinding), the effective System.Net.Security.ProtectionLevel is ProtectionLevel.None for the whole contract. The result is that depending upon the endpoint binding, clients can require different message or transport level security protection even when the contract specifies ProtectionLevel.None.</p> </blockquote> <p>So, if you don't specify ProtectionLevel in ServiceContract attribute, WCF will define ProtectionLevel based on your web.config. If you're using for example Ws2007 and BasicHttpBinding, BasicHttpBinding will fail with your exception.

38,877,689 | 0 | <p>Starting from Outlook 2013 you can reorder folders however you like and Outlook would remember the order. The key property is <code>PR_SORT_POSITION</code>. Here’s the definition:</p> <blockquote> <h1>define PR_SORT_POSITION PROP_TAG( PT_BINARY, 0x3020)</h1> </blockquote> <p>Outlook will use this property as part of it’s sort order when requesting folders from a provider, so it’s important that your provider can handle sorting on a binary property – or can fake it when asked to sort by this property. Outlook will also use this property directly when deciding where to insert nodes in the visible tree, so it’s also important that your provider can return this property when Outlook looks for it on a folder.</p> <p>There’s a second property Outlook will use for custom sort ordering:</p> <blockquote> <h1>define PR_SORT_PARENTID PROP_TAG( PT_BINARY, 0x3021)</h1> </blockquote> <p>As the name suggests, this property stores an entry ID which can be used to sort a folder under a different node than it’s natural parent. Normally, a folder will be sorted under the folder represented by <code>PR_PARENT_ENTRYID</code>. This property allows you to suggest a different parent for display.</p> <p>By presetting these properties appropriately, you can direct Outlook in how you wish your provider’s folders to be sorted. And if you allow Outlook to write to these properties, you can preserve whatever sort order your users desire.</p> <p>So, theoretically you can set these properties from VBA. The <a href="https://msdn.microsoft.com/en-us/library/office/ff869735.aspx?f=255&MSPPError=-2147217396" rel="nofollow">PropertyAccessor</a> class can help you with such tasks.

16,497,020 | 0 | .Net MVC binding dynamic Type to a Model at runtime <p>I have a slightly long conceptual question I'm wondering if somebody could help me out with. </p> <p>In MVC I've built a website which builds grids using <a href="http://demos.kendoui.com/web/grid/index.html" rel="nofollow">kendoui's framework</a>. </p> <p>All the grids on my website are constructed exactly the same except for the model they use and the CRUD methods that need to be implemented for each model. I set things up where each Model implement an interface for CRUD methods like below to get the logic all in one place.</p> <pre><code>//Actual interface has variables getting passed public interface IKendoModelInterface { void Save(); void Read(); void Delete(); } public class Model1: IKendoModelInterface { [Key] public int IdProperty1 { get; set; } public int SomeProperty2 { get; set; } public string SomeProperty3 { get; set; } public void Save(){ //Implement Save } public void Read(){ //Implement Read } public void Delete(){ //Implement Delete } } </code></pre> <p>Then to speed up the writing of all the scaffolding Action methods needed to get the grids to work I created an abstract Controller that can call the interface methods of the Model that gets passed into it. </p> <pre><code> //Implement the AJAX methods called by the grid public abstract class KendoGridImplController<T> : Controller where T : class, IKendoModelInterface { // Method called from kendo grid public virtual ActionResult Create([DataSourceRequest] DataSourceRequest request, [Bind(Prefix = "models")]IEnumerable<T> createdRecords) { //Invoke Create Method for Model and return results } public virtual ActionResult Read([DataSourceRequest]DataSourceRequest request, int Id) { //Invoke read method for model and return results } //Update and Delete also implemented.. } </code></pre> <p>Then I just need a Controller per model that implements the abstract controller above passing in the type of Model being used.</p> <pre><code> public class ResponsibilityMatrixController : KendoGridImplController<Model1> { //Set up the page the grid will be on public ActionResult Index(int id) { return View("SharedGridView", id); } //Can override abstract methods if needed but usually won't need to } </code></pre> <p>I'm wondering if I can take this one step further or if I've reached the end of the road. To me it just seems like more repeated code if I have to create a controller per Model that does nothing but pass in the type to the abstract controller and calls the same View. </p> <p>I attempted for quite a while yesterday to figure out if I could dynamically assign the type to the abstract controller. I setup something where I was sending back the type of model via strings and I could still invoke the methods needed. Where it failed, was that the mapping could no longer be done on any of the controller actions by default since the type isn't known at compile time. eg </p> <pre><code>public virtual ActionResult Create([DataSourceRequest] DataSourceRequest request, [Bind(Prefix = "models")]IEnumerable<T> createdRecords) </code></pre> <p>createdRecords can't be bound like this if T that's passed in is an interface and not the Model itself and I've found no real way to map the form data to an instance of a type that isn't known at compile time. </p> <p>I'm wondering if there's an easy way to do this mapping between an instance of the type of object getting passed in that I can figure out at runtime, if there's some other way to set this up that I'm overlooking or if both those things are going to be way too much work and I should just not attempt something like this and build a controller per model like I do now? </p> |

16,162,881 | 0 | WPF: Drawing normalized polygons that resize to fit their container <p>I'm trying to create a usercontrol that is capable of drawing polygons on the screen. These polygons have points all between 0,0 and 1,1 (normalized). When drawing, the polygon should fill the space given to it. As such, a value of 1,1 would correspond to width,height in the container.</p> <p>I've tried applying renderTransforms, but that results in the line widths getting scaled as well. The line widths should be the same (this is vectorized polygon information I'm trying to display).</p> <p>Can anyone think of the best way to go about doing this?</p> <p>Thanks</p> |

28,447,009 | 0 | <p>The <code>OutOfMemoryException</code> is almost certainly coming from the JSON serialization of your <code>Customer</code> object. As such, the issue isn't one of NEST or Elasticsearch functionality, but of JSON.NET functionality.</p> <p>You could handle this in one of two ways:</p> <p><strong>1. Serialize the large object selectively</strong></p> <p><a href="http://james.newtonking.com/archive/2009/10/23/efficient-json-with-json-net-reducing-serialized-json-size" rel="nofollow">This article</a> by the author of JSON.NET discusses reducing the size of objects. You might furnish properties with the <a href="http://www.newtonsoft.com/json/help/html/T_Newtonsoft_Json_JsonIgnoreAttribute.htm" rel="nofollow">JsonIgnoreAttribute property</a> to instruct the serializer to ignore certain properties. Or an implementation of <a href="http://www.newtonsoft.com/json/help/html/T_Newtonsoft_Json_Serialization_IContractResolver.htm" rel="nofollow">IContractResolver</a> may be less intrusive on the definitions of your EF objects (especially given that they're database-first generated), but I'm not sure whether this can be used in conjunction with the NEST dependency on JSON.NET.</p> <p>If you're out of options for dealing with NEST's dependency on JSON.NET, you could always find another way to serialize your object and "go raw" by using the Elasticsearch.NET syntax instead of NEST (which essentially builds on-top of Elasticsearch.NET). So instead of a call to <code>ElasticClient.Index(..)</code>, make a call to <code>ElasticClient.Raw.Index(..)</code>, where the <code>body</code> parameter is a JSON string representation (of your own construction) of the object you wish to index.</p> <p><strong>2. Project the large object to a smaller data transfer object</strong></p> <p>Instead of indexing a <code>Customer</code> object, map only the properties you want to index into a data transfer object (DTO) that targets your Elasticsearch schema / document type.</p> <pre><code>foreach (Customer c in db.Customer.Where(a => a.Active == true)) client.Index(new MyElasticsearchTypes.Customer() { CustomerId = c.CustomerId, CustomerName = c.CustomerName, Description = c.Description }); </code></pre> <p>In C#, you've got a lot of options for how to handle creation of such a DTO, including:</p> <ol> <li>Explicitly typed objects with manual mapping (like my example).</li> <li>Explicitly typed objects with a mapping tool like <a href="https://www.nuget.org/packages/AutoMapper/" rel="nofollow">AutoMapper</a>.</li> <li>Dynamic objects.</li> </ol> <p><strong>Flat by design</strong></p> <p>Be aware that using Elasticsearch isn't a case of simply throwing your data into "the index". You need to start thinking in terms of "documents", and come to terms with what that means when you're trying to index data that has come from a relational database. The Elasticsearch guide article <a href="http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/data-in-data-out.html" rel="nofollow">Data In, Data Out</a> is a good place to start reading. Another article called <a href="http://www.elasticsearch.org/blog/managing-relations-inside-elasticsearch/" rel="nofollow">Managing relations inside Elasticsearch</a> is particularly relevant to your situation:</p> <blockquote> <p>At it's heart, Elasticsearch is a flat hierarchy and trying to force relational data into it can be very challenging.

I downloaded the VS11 Developer Preview from the link below. <a href="http://www.microsoft.com/download/en/details.aspx?id=27543">http://www.microsoft.com/download/en/details.aspx?id=27543</a></p> <p>I created a sample C# Console App, and add the Test Library from the MSTest project template. Then I created a sample Unit Test, and rebuild the solution. When I open the Test Explorer (View->OtherWindows->UnitTest Explorer) I do not see any tests loaded.</p> <p>I only see a message saying… “No test discovered. Please build your project and ensure the appropriate test framework adapter is installed”.</p> <p>I assume the MSTest adapter is automatically installed. If not I’m not even sure how to install an adapter. </p> <p>I could be missing something here but I cannot figure it out. Has anyone experiencing this issue?</p> |

26,692,442 | 0 | <p>To quote <a href="http://dev.mysql.com/doc/refman/5.5/en/case-sensitivity.html" rel="nofollow">the documentation</a>:</p> <blockquote> <p>The default character set and collation are latin1 and latin1_swedish_ci, so nonbinary string comparisons are case insensitive by default. This means that if you search with col_name LIKE 'a%', you get all column values that start with A or a. To make this search case sensitive, make sure that one of the operands has a case sensitive or binary collation. For example, if you are comparing a column and a string that both have the latin1 character set, you can use the COLLATE operator to cause either operand to have the latin1_general_cs or latin1_bin collation</p> </blockquote> <p>You can overcome this by explicitly using a case sensitive collation:</p> <pre><code>select * from names where name='Bill' COLLATE latin1_general_cs </code></pre> |
1,856,992 | 0 | <p>Hey, someone has implemented a module to do this, and it works in Netbeans 6.5.1 - perfect for you. I'm hanging out to see an equivalent for 6.7.1. Maybe they should add it to 6.8!</p> <p><a href="http://wiki.netbeans.org/JavaGoToImplementation" rel="nofollow noreferrer">http://wiki.netbeans.org/JavaGoToImplementation</a></p> <p>Go To Implementation is built in for recent versions of NetBeans.

5,635,065 | 0 | <p>Without knowing exactly how this should work I can say that you write outside of the <code>p</code> vector on </p> <pre><code> for (i=0; i < rptr->n; i++) { lptr->keys[lptr->n + 1 + i] = rptr->keys[i]; // When you delete key 84, rptr->n is 4 at one point which takes you outside // p[M] lptr->p[lptr->n + 2 + i] = rptr->p[i+1]; } </code></pre> <p>Valgrind is a good tool to use, and I found this problem by <code>valgrind -v --leak-check=full <your executable></code></p> |
19,059,223 | 0 | <p>The error occurs because when the class body executes the Bid class object has not yet been created.</p> <p>You cannot have a model class contain a substructure of the same class -- it would result in infinite space. A StructuredProperty <em>physically</em> includes the fields of another model in the current model.</p> <p>So I recommend deleting the StructuredProperty line.</p> <p>You will then get a similar error on the KeyProperty line, but for KeyProperty it can be fixed by using a string ('Bid') instead of a direct class reference (Bid).</p> <p>You'll have to use outbyd_by_key.get() to access the bid's contents.</p> |

I've tried running it as a normal user and administrator but nothing happens. Not even a processor in the Task Manager opens.</p> <p>What could cause this? Is it because Git hasn't been updated for Windows 10 yet, or is it something else? I just did a clean install of Windows 10.</p> |
