  • UIWebView leak? Can someone confirm?

    - by Shaggy Frog
    I was leak-testing my current project and I'm stumped. I've been browsing like crazy and tried everything except chicken sacrifice. I just created a tiny toy project app from scratch and I can duplicate the leak in there. So either UIWebView has a leak or I'm doing something really silly. Essentially, it boils down to a loadRequest: call to a UIWebView object, given an URLRequest built from an NSURL which references a file URL, for a file in the app bundle, which lives inside a folder that Xcode is including by reference. Phew. The leak is intermittent but still happens ~75% of the time (in about 20 tests it happened about 15 times). It only happens on the device -- this does not leak in the simulator. I am testing targeting both iPhone OS 3.1.2 and 3.1.3, on an original (1st Gen) iPod Touch that is using iPhone OS 3.1.3. To reproduce, just create a project from scratch. Add a UIWebView to the RootViewController's .xib, hook it up via IBOutlet. In the Finder, create a folder named "html" inside your project's folder. Inside that folder, create a file named "dummy.html" that has the word "Test" in it. (Does not need to be valid HTML.) Then add the html folder to your project in Xcode by choosing "Create Folder References for any added folders" Add the following to viewDidLoad NSString* resourcePath = [[NSBundle mainBundle] resourcePath]; NSString* filePath = [[resourcePath stringByAppendingPathComponent:@"html"] stringByAppendingPathComponent:@"dummy.html"]; NSURL* url = [[NSURL alloc] initFileURLWithPath:filePath]; NSURLRequest* request = [NSURLRequest requestWithURL:url]; // <-- this creates the leak! [browserView loadRequest:request]; [url release]; I've tried everything from setting delegate for the UIWebView and implementing UIWebViewDelegate, to not setting a delegate in IB, to not setting a delegate in IB and explicitly setting the web view's delegate property to nil, to using alloc/init instead of getting autoreleased NSURLRequests (and/or NSURLs)... I tried the answer to a similar question (setting the shared URL cache to empty) and that did not help. Can anyone help?

  • WCF Timeout issue - should there even be a socket connection?

    - by stiank81
    I have a .Net application which is split into a client and server side. The communication between them is handled using WCF. I'm not using the automagic service references, but instead I've built the connection manually like described in the Screencast by Miguel Castro. Summarized this means that I create a console application on the server side that holds ServiceHost objects for the different services: var myServiceHost = new System.ServiceModel.ServiceHost(typeof(MyService), new Uri("net.tcp://localhost:8002")); myServiceHost.Open(); And on the client side I have service proxies creating channels using the ChannelFactory: IMyService proxy = new ChannelFactory<IMyService>("MyServiceEndpoint").CreateChannel(); The client and server side share the service contract defined in the interface IMyService. And another advantage is that I get minimal App.config files - without all the autogenerated stuff created through the Service References. Example from client side: <?xml version="1.0"?> <configuration> <system.serviceModel> <client> <endpoint address="net.tcp://localhost:8002/MyEndpoint" binding="netTcpBinding" contract="IMyService" name="MyServiceEndpoint"/> </client> </system.serviceModel> </configuration> So - to my problem. I create the proxy once, and it holds a channel all the way through the application. However, if I leave the application without use for a few minutes the channel has timed out, and I get the following exception: The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:00:59.9979998'. How do I prevent this? I'm assuming I need to specify a higher timeout in my configuration? But I don't want it to ever time out. But on the other hand - I don't want a socket connection! Do I need one? Thought I could go connection less with WCF... What's the permanent solution and best practice on solving this? Set timeout to "never".. Create a new channel for each request? I'm assuming there is some overhead creating the channel?.. Increase the timeout to e.g. 5minutes and create new channel if the connection did timeout? Make it connection less somehow? (Without the overhead of creating channels..) Something else...

  • Windows Batch Script to Replace Environment Variables in a File

    - by skb
    Hi. I want to write a batch file that will take the contents of a file, and replace any environment variable references inside the file with the actual environment variable values. Is this possible? Basically, if a file had this: %PROGRAM FILES%\Microsoft SQL Server\ then I would want the file contents to become: C:\Program Files\Microsoft SQL Server\ after the batch script ran. This is just one example, but I want ALL environment variables to be expanded. Thanks in advance for any help!

  • How to force reload all vendor/plugins in rails 2.3 (development mode)

    - by tsdbrown
    We have an application with a app/model that references another model stored in a plugin. When the app/model level is reloaded on the second and further requests and that relies on our model in vendor/plugins/... (which stays loaded) it fails (can't dup nil class). We've tried setting config.reload_plugins = true in the development.rb but this doesn't seem to do it. Does anybody know a way to handle this?

  • FxCop for .NET 4.0

    - by Jim McKeeth
    I know Visual Studio 2010 has a new Code Analysis tool built in, but that is only for the premium and ultimate editions. From what I can see the latest FxCop supports .NET 3.5 SP1. Searching I wasn't able to find any references to an FxCop for .NET 4.0. Is there plans to continue to offer FxCop and for it to support .NET 4.0? Where would I find more information about it and download it?

  • Embedding JARs into the OSGi bundle with maven-bundle-plugin

    - by Ivan Dubrov
    I’m trying to embed some JARs into single OSGi bundle using the feature of maven-bundle-plugin The thing that worries me is that all packages of embedded JARs are put into the Import-Package header of the generated MANIFEST.MF. If I specify explicitly to use only the packages I need, like in the following snippet: Import-Package: org.osgi.framework The build fails with BND error (unresolved references). So, the question here is how can I build the bundle with embedded JARs with "Import-Package" header I need?

  • PowerShell - Shorten namespace names so it's easier to access types

    - by Adam Driscoll
    Is there a method of shortening PowerShell namespace references? Typing [RootNameSpace1.NameSpace2.Namepsace3+SomeEnum]::SomeValue is taxing and not a very good user expierence. I realize that you can reference System level objects without a namespace such that [Type]::GetType(... will work. Is there some manifest I could create or command I could use to shorten lengthy namespaces?

  • What's the meaning of “Monty Python’s Flying Circus” phrase on Python?

    - by Zignd
    I just started studying Python using the Python 3.2 Tutorial and on the introduction is written: By the way, the language is named after the BBC show “Monty Python’s Flying Circus” and has nothing to do with reptiles. Making references to Monty Python skits in documentation is not only allowed, it is encouraged! But I have to say that I did not understood this part: “Monty Python’s Flying Circus”, I'm Brazilian and even Google Translator don't know how to answer it. Can someone explain me this phrase?

    - by Lloyd
    Hi, Has anyone had this error before when running reports in Crystal Reports 2008: Character set encoding from transport information [UTF-8] does not match with character set encoding in the received SOAP message [iso-8559]. I presume this indicates a file needs changing, but trying to fint it is causing me a real headache. There are references to UTF-8 all over the server. Any help would be great. Thanks, Lloyd.

  • healthy DLL reference broken after compile multi-project solution

    - by Code Sherpa
    Hi. I have a solution with multiple class libraries. When I compile each individual library (and the web site by itself) compilation always succeeds. But, when I compile the solution as a whole, one of the library references fails with a little yellow exclamation mark next to the failed library. I am guessing this has to do with the build order? Can somebody suggest what i have to do to resolve this? Thanks in advance.

  • Can I run asp.net mvc 1 on .net 4?

    - by Jenea
    I have a asp.net mvc site that references a couple of libraries. Recently I discovered that it is necessary to migrate those dlls to .net 4 (I mean compile them for .net 4). Can I run asp.net mvc 1 on .net 4. Migration to asp.net mvc 2 is postponed because of the removal of response.WriteSubstitution(...) method.

  • I have 5 links that open the same modalpopup?

    - by JPJedi
    I have 5 links that are on the same form but I would like them all to reference the same AJAX modalpopup extender. I am basically showing a panel with the same view layout with just different data depending on which link is pressed, showing different match scores from games. The only way I can get it to work is have 5 panels with unique names and each link references its own panel. Can I get all the links to call one panel? Thanks

  • Is this a valid LGPL scenario?

    - by themapguyde
    Suppose I have Project X under closed source. It references/links to component Y which is LGPL, we make modifications to component Y 1) We release Project X binaries with the source to the modified component Y OR 2) We contribute component Y modifications back upstream (to the original author(s)) and release Project X binaries without component Y source. Does any of these scenarios comply with the LGPL?
