36,411,200 | 0 | <p>If using ASP.NET (this includes MVC and Web API, Web Forms, etc) and AutoFac you should register all your components using the extension method <code>.InstancePerRequest()</code>. The only exception is for components that are thread safe and where you do not have to worry about errors/unexpected results occurring from one request accessing the same (stale) data as another. An example might be a Factory or a Singleton.</p> <p>Example of use on a line of code:</p> <pre><code>builder.Register(c => new UserStore<ApplicationUser>(c.Resolve<ApplicationDataContext>())).AsImplementedInterfaces().InstancePerRequest(); </code></pre> <p>This ensures that every new incoming Http Request will get its own copy of that implementation (resolved and injected hopefully via an interface). Autofac will also cleanup the Disposable instances at the end of each request.</p> <p>This is the behavior you need. It ensures that there is no cross request interference (like one request manipulating data on a shared dbcontext on another request). It also ensures that data is not stale as it is cleaned up after each request ends.</p> <p>See <a href="http://docs.autofac.org/en/latest/lifetime/instance-scope.html#instance-per-request" rel="nofollow">the Autofac documentation</a> for more details (here an excerpt).</p> <blockquote> <h3>Instance Per Request</h3> <p>Some application types naturally lend themselves to “request” type semantics, for example ASP.NET web forms and MVC applications. In these application types, it’s helpful to have the ability to have a sort of “singleton per request.”</p> <p>Instance per request builds on top of instance per matching lifetime scope by providing a well-known lifetime scope tag, a registration convenience method, and integration for common application types. Behind the scenes, though, it’s still just instance per matching lifetime scope.</p> </blockquote> <p>Changing your DI definitions above to include this should resolve your issues (I think based on what you have provided). If not then it might be a problem with your Identity registration in which case you should post that code so it can be scrutinized.</p> |

35,069,582 | 0 | Why google doesnt index my single page app properly? <p>Since some time google <a href="https://developers.google.com/webmasters/ajax-crawling/docs/learn-more" rel="nofollow">officially depreceated ajax crawling scheme</a> they came up with back in 2009 so I decided to get rid of generating snapshots in phantomJS for _escaped_fragment and rely on google to render my single page app like a modern browser and discover its content. <a href="https://googlewebmastercentral.blogspot.com.au/2015/10/deprecating-our-ajax-crawling-scheme.html" rel="nofollow">They describe it in here</a>. But now I seem to have a problem.</p> <p>Google indexed my page (at least I can see in webmastertools it has) but when using webmastertools I look at <code>google index-->content keywords</code> it shows non processed content of my angularJS templates only and names of my binded variable names e.g. <code>{{totalnewprivatemessagescount}}</code> etc. The keywords do not contain words that should should be generated by ajax calls when Javascript executes so e.g. <code>fighter</code> is not even in there and it should be all over the place.</p> <p>Now, when I use <code>Crawl-->Fetch as google-->Fetch and render</code> the snapshot what google bot sees is very much the same as what user sees and is clearly generated using Javascript. The Fetch HTML tab though shows only source without being processed using JS which I'm guessing is fine.</p> <p>Now my question is why google didn't index my website properly? Is there anything I implemented incorrectly somewhere? The website is live at <a href="https://www.fightersconnect.com" rel="nofollow">https://www.fightersconnect.com</a> and thanks for any advice.</p> |

For example:</p> <pre><code>app.factory('healthService', function() { var state = { healths: [...] }; return { getState: function() { return state; }, updateHealths: function() { state.healths = [...]; } }; }); </code></pre> <p>Then inside your controller:</p> <pre><code>$scope.healthState = healthService.getState(); </code></pre> <p>Then to reference your healths from your html, use:</p> <pre><code><div ng-repeat="health in healthState.healths"></div> </code></pre> |

17,957,443 | 0 | <p>Well, for starters you'd have to avoid the client's navigation cache (often a back/forward doesn't actually pull the page back down).</p> <p>After that hurdle you can look at (ironically) using a session variable to store if it's been viewed [output] and only dump it to the page once.</p> <p>if that seems to much, you could just add a cookie check in the function so when it's run (and re-run) it checks for a cookie and, when absent, makes an alert and sets a cookie. Pseudocode:</p> <pre><code>function showAlert(msg){ if (cookie[msg] == null){ // a cookie doesn't exist for this msg alert(msg); // alert the msg cookie[msg] = true; // set the cookie so the next pass is ignored } } </code></pre> |

1,267,031 | 0 | What does fragmented memory look like? <p>I have a mobile application that is suffering from slow-down over time. My hunch, (In part fed by <a href="http://developer.sonyericsson.com/site/global/techsupport/tipstrickscode/java/p_avoidingmemoryfragment.jsp" rel="nofollow noreferrer">this article</a>,) is that this is due to fragmentation of memory slowing the app down, but I'm not sure. Here's a pretty graph of the app's memory use over time:</p> <p><img src="http://kupio.com/image-dump/fragmented.png" alt="fraggle rock"></p> <p>The 4 peaks on the graph are 4 executions of the exact same task on the app. I start the task, it allocates a bunch of memory, it sits for a bit (The flat line on top) and then I stop the task. At that point it calls System.gc(); and the memory gets cleaned up.</p> <p>As can be seen, each of the 4 runs of the exact same task take longer to execute. The low-points in the graph all return to the same level so there do not seem to be any memory leaks between task runs.</p> <p>What I want to know is, is memory fragmentation a feasible explanation or should I look elsewhere first, bearing in mind that I've already done a lot of looking? The low-points on the graph are relatively low so my assumption is that in this state the memory would not be very fragmented since there can't be a lot of small memory holes to be causing problems.</p> <p>I don't know how the j2me memory allocator works though, so I really don't know. Can anyone advise? Has anyone else had problems with this and recognises the memory profile of the app?</p> |

37,687,231 | 0 | Java jersey validation <p>I'm using the validation in Java Jersey, and i'm building an application where it should be possible to save a draft of something. But before it is published, i would like it to be valid, using the annotations in the view model. When publishing, the same savemethod, for draft, is invoked. Therefor i cannot use the annotation in the method (methodName(@Valid ViewmodelName)). Can i somehow invoke a method to validate the annotations in the viewModel? Something like model->isValid(). Alternatively i could make two viewmodels; one for draft and one for published, but seems kind of double work.</p> <p>Best regards</p> |
