  • Using ASP.NET Session for Lifetime Management (Unity)

    - by Sigray
    I am considering using Unity to manage the lifetime of a custom user class instance. I am planning on extending the LifetimeManager with a custom ASP.NET session manager. What I want to be able to do is store and retrieve the currently logged in user object from my custom classes, and have Unity get the instance of User from the session object in ASP.NET, or (when in a Win32 project) retrieve it statically or from the current thread. So far my best solution is to create a static instance of my Unity container on startup, and use the Resolve method to get my User object from each of my classes. However, this seems to create a dependency on the unity container in my other classes. What is the more "Unity" way of accomplishing this goal? I would like to be able to read/replace the current User instance from any class.

  • IPsec tunnel to Android device not created even though there is an IKE SA

    - by Quentin Swain
    I'm trying to configure a VPN tunnel between an Android device running 4.1 and a Fedora 17 Linux box running strongSwan 5.0. The device reports that it is connected and strongSwan statusall returns that there is an IKE SA, but doesn't display a tunnel. I used the instructions for iOS in the wiki to generate certificates and configure strongSwan. Since Android uses a modified version of racoon this should work and since the connection is partly established I think I am on the right track. I don't see any errors about not being able to create the tunnel. This is the configuration for the strongSwan connection conn android2 keyexchange=ikev1 authby=xauthrsasig xauth=server left=96.244.142.28 leftsubnet=0.0.0.0/0 leftfirewall=yes leftcert=serverCert.pem right=%any rightsubnet=10.0.0.0/24 rightsourceip=10.0.0.2 rightcert=clientCert.pem ike=aes256-sha1-modp1024 auto=add This is the output of strongswan statusall Status of IKE charon daemon (strongSwan 5.0.0, Linux 3.3.4-5.fc17.x86_64, x86_64): uptime: 20 minutes, since Oct 31 10:27:31 2012 malloc: sbrk 270336, mmap 0, used 198144, free 72192 worker threads: 8 of 16 idle, 7/1/0/0 working, job queue: 0/0/0/0, scheduled: 7 loaded plugins: charon aes des sha1 sha2 md5 random nonce x509 revocation constraints pubkey pkcs1 pkcs8 pgp dnskey pem openssl fips-prf gmp xcbc cmac hmac attr kernel-netlink resolve socket-default stroke updown xauth-generic Virtual IP pools (size/online/offline): android-hybrid: 1/0/0 android2: 1/1/0 Listening IP addresses: 96.244.142.28 Connections: android-hybrid: %any...%any IKEv1 android-hybrid: local: [C=CH, O=strongSwan, CN=vpn.strongswan.org] uses public key authentication android-hybrid: cert: "C=CH, O=strongSwan, CN=vpn.strongswan.org" android-hybrid: remote: [%any] uses XAuth authentication: any android-hybrid: child: dynamic === dynamic TUNNEL android2: 96.244.142.28...%any IKEv1 android2: local: [C=CH, O=strongSwan, CN=vpn.strongswan.org] uses public key authentication android2: cert: "C=CH, O=strongSwan, CN=vpn.strongswan.org" android2: remote: [C=CH, O=strongSwan, CN=client] uses public key authentication android2: cert: "C=CH, O=strongSwan, CN=client" android2: remote: [%any] uses XAuth authentication: any android2: child: 0.0.0.0/0 === 10.0.0.0/24 TUNNEL Security Associations (1 up, 0 connecting): android2[3]: ESTABLISHED 10 seconds ago, 96.244.142.28[C=CH, O=strongSwan, CN=vpn.strongswan.org]...208.54.35.241[C=CH, O=strongSwan, CN=client] android2[3]: Remote XAuth identity: android android2[3]: IKEv1 SPIs: 4151e371ad46b20d_i 59a56390d74792d2_r*, public key reauthentication in 56 minutes android2[3]: IKE proposal: AES_CBC_256/HMAC_SHA1_96/PRF_HMAC_SHA1/MODP_1024 The output of ip -s xfrm policy src ::/0 dst ::/0 uid 0 socket in action allow index 3851 priority 0 ptype main share any flag (0x00000000) lifetime config: limit: soft 0(bytes), hard 0(bytes) limit: soft 0(packets), hard 0(packets) expire add: soft 0(sec), hard 0(sec) expire use: soft 0(sec), hard 0(sec) lifetime current: 0(bytes), 0(packets) add 2012-10-31 13:29:08 use -

  • Using Structuremap to manage ObjectContext Lifetime in ASP.NET MVC

    - by Diego Correa
    Hi, what I want to know If there is a way or an good article on how to manage the objectcontext life cycle through structuremap (I saw an example with ninject). Since I'm new to the methods and possibilities of SM I really don't know How/If possible to make it. In the first moment I wanted to make a singleton of the objectcontext per httpcontext. Thanks for any advice.

  • WCF Service Client Lifetime

    - by Burt
    I have a WPF appliction that uses WCF services to make calls to the server. I use this property in my code to access the service private static IProjectWcfService ProjectService { get { _projectServiceFactory = new ProjectWcfServiceFactory(); return _projectServiceFactory.Create(); } } The Create on the factory looks like this public IProjectWcfService Create() { _serviceClient = new ProjectWcfServiceClient(); //ToDo: Need some way of saving username and password _serviceClient.ClientCredentials.UserName.UserName = "Brendan"; _serviceClient.ClientCredentials.UserName.Password = "password"; return _serviceClient; } To access the service methods I use somethingn like the following. ProjectService.Save(dto); Is this a good approach for what I am trying to do? I am getting an errorthat I can't track down that I think may be realted to having too many service client connections open (is this possible?) notice I never close the service client or reuse it. What would the best practice for WCF service client's be for WPF calling? Thanks in advance...

  • C stack/scope, variable's lifetime after functions ends

    - by Ranking Stackingblocks
    void someFunc() { int stackInt = 4; someOtherFunc(&stackInt); } Is it the case that stackInt's address space could be reallocated after someFunc ends, making it unsafe to assume that the value passed to someOtherFunc represents the stackInt variable with value 4 that was passed to it? In other words, should I avoid passing stack variables around by address and expecting them to still be alive after the function they were initialised in has ended?

  • applicaion and local service lifetime

    - by rayman
    As i understoond, if we have local service of some application, as soon as the application goes down, the service goes down as well - is that true? and if it is, how can we make an application to run all the time without go down? (without using Alarm manager). i though that the purpose of local service is to answer this situation: " to make the application everlasting" please, if some1 could explain me this better, thanks, ray.

  • Lifetime of a const string literal returned by a function

    - by Neeraj
    Consider this code: const char* someFun() { // ... some stuff return "Some text!!" } int main() { { // Block: A const char* retStr = someFun(); // use retStr } } My question is in the function sumFun() where is "some Text!!", stored (i think may be in some static area in ROM) and what will be its scope? Will the memory pointed by retStr be occupied throughout the program or be released once the block A exits? -- Thanks

  • Android Static Variable Scope and Lifetime

    - by Edison
    I have an application that has a Service uses a ArrayList to store in the background for a very long time, the variable is initialized when the service started. The service is in the background and there will be frequent access to the variable (that's why i don't want to use file management or settings since it will be very expensive for a file I/O for the sake of battery life). The variable will likely to be ~1MB-2MB over its life tie. Is it safe to say that it will never be nulled by GC or the system or is there any way to prevent it? Thanks.

  • Singelton restricted to instance of dll

    - by codeySmurf
    If I create a singleton class in the context of a dll, the singleton class is instantiated once and used by all instances of the dll. I am using a dll as a plug-in for an application. Now the following thing came to my mind: If I use a singleton Class, it will be shared across multiple instances of the plug-in. However, this makes it difficult to manage the lifetime of the singleton class efficiently. The only way I could think of would be to use a reference count and to make the singleton delete its self when the reference count is 0. Does anyone have any better ideas on that? Is there any good way to restrict the singleton object to one instance of the dll? Language is c++

  • Getting a SecurityToken from a RequestSecurityTokenResponse in WIF

    - by Shawn Cicoria
    When you’re working with WIF and WSTrustChannelFactory when you call the Issue operation, you can also request that a RequestSecurityTokenResponse as an out parameter. However, what can you do with that object?  Well, you could keep it around and use it for subsequent calls with the extension method CreateChannelWithIssuedToken – or can you? public static T CreateChannelWithIssuedToken<T>(this ChannelFactory<T> factory, SecurityToken issuedToken);   As you can see from the method signature it takes a SecurityToken – but that’s not present on the RequestSecurityTokenResponse class. However, you can through a little magic get a GenericXmlSecurityToken by means of the following set of extension methods below – just call rstr.GetSecurityTokenFromResponse() – and you’ll get a GenericXmlSecurityToken as a return. public static class TokenHelper { /// <summary> /// Takes a RequestSecurityTokenResponse, pulls out the GenericXmlSecurityToken usable for further WS-Trust calls /// </summary> /// <param name="rstr"></param> /// <returns></returns> public static GenericXmlSecurityToken GetSecurityTokenFromResponse(this RequestSecurityTokenResponse rstr) { var lifeTime = rstr.Lifetime; var appliesTo = rstr.AppliesTo.Uri; var tokenXml = rstr.GetSerializedTokenFromResponse(); var token = GetTokenFromSerializedToken(tokenXml, appliesTo, lifeTime); return token; } /// <summary> /// Provides a token as an XML string. /// </summary> /// <param name="rstr"></param> /// <returns></returns> public static string GetSerializedTokenFromResponse(this RequestSecurityTokenResponse rstr) { var serializedRst = new WSFederationSerializer().GetResponseAsString(rstr, new WSTrustSerializationContext()); return serializedRst; } /// <summary> /// Turns the XML representation of the token back into a GenericXmlSecurityToken. /// </summary> /// <param name="tokenAsXmlString"></param> /// <param name="appliesTo"></param> /// <param name="lifetime"></param> /// <returns></returns> public static GenericXmlSecurityToken GetTokenFromSerializedToken(this string tokenAsXmlString, Uri appliesTo, Lifetime lifetime) { RequestSecurityTokenResponse rstr2 = new WSFederationSerializer().CreateResponse( new SignInResponseMessage(appliesTo, tokenAsXmlString), new WSTrustSerializationContext()); return new GenericXmlSecurityToken( rstr2.RequestedSecurityToken.SecurityTokenXml, new BinarySecretSecurityToken( rstr2.RequestedProofToken.ProtectedKey.GetKeyBytes()), lifetime.Created.HasValue ? lifetime.Created.Value : DateTime.MinValue, lifetime.Expires.HasValue ? lifetime.Expires.Value : DateTime.MaxValue, rstr2.RequestedAttachedReference, rstr2.RequestedUnattachedReference, null); } }

  • What happens to an ActiveX control (COleControl) after the call to OnDestroy() ?

    - by richj
    I have an ActiveX control written in C++ that runs in Internet Explorer 8. Most of the time (approx 90%) when the tab or browser containing the control is closed, there is an access violation like this: The thread 'Win32 Thread' (0x1bf0) has exited with code 0 (0x0). Unhandled exception at 0x77b3b9fd in iexplore.exe: 0xC0000005: Access violation reading location 0x65007408. The access violation occurs after the call to OnDestroy() but before the call to the control's destructor. The debug output says: No symbols are loaded for any call stack frame. The source code cannot be displayed. None of my code is present in the stacktrace, although perhaps the heap was corrupted at some earlier point during execution. What lifecycle events does an ActiveX control receive between the call to OnDestroy() and the control's destructor?

  • Using Unity – Part 3

    - by nmarun
    The previous blog was about registering and invoking different types dynamically. In this one I’d like to show how Unity manages/disposes the instances – say hello to Lifetime Managers. When a type gets registered, either through the config file or when RegisterType method is explicitly called, the default behavior is that the container uses a transient lifetime manager. In other words, the unity container creates a new instance of the type when Resolve or ResolveAll method is called. Whereas, when you register an existing object using the RegisterInstance method, the container uses a container controlled lifetime manager - a singleton pattern. It does this by storing the reference of the object and that means so as long as the container is ‘alive’, your registered instance does not go out of scope and will be disposed only after the container either goes out of scope or when the code explicitly disposes the container. Let’s see how we can use these and test if something is a singleton or a transient instance. Continuing on the same solution used in the previous blogs, I have made the following changes: First is to add typeAlias elements for TransientLifetimeManager type: 1: <typeAlias alias="transient" type="Microsoft.Practices.Unity.TransientLifetimeManager, Microsoft.Practices.Unity"/> You then need to tell what type(s) you want to be transient by nature: 1: <type type="IProduct" mapTo="Product2"> 2: <lifetime type="transient" /> 3: </type> 4: <!--<type type="IProduct" mapTo="Product2" />--> The lifetime element’s type attribute matches with the alias attribute of the typeAlias element. Now since ‘transient’ is the default behavior, you can have a concise version of the same as line 4 shows. Also note that I’ve changed the mapTo attribute from ‘Product’ to ‘Product2’. I’ve done this to help understand the transient nature of the instance of the type Product2. By making this change, you are basically saying when a type of IProduct needs to be resolved, Unity should create an instance of Product2 by default. 1: public string WriteProductDetails() 2: { 3: return string.Format("Name: {0}<br/>Category: {1}<br/>Mfg Date: {2}<br/>Hash Code: {3}", 4: Name, Category, MfgDate.ToString("MM/dd/yyyy hh:mm:ss tt"), GetHashCode()); 5: } Again, the above change is purely for the purpose of making the example more clear to understand. The display will show the full date and also displays the hash code of the current instance. The GetHashCode() method returns an integer when an instance gets created – a new integer for every instance. When you run the application, you’ll see something like the below: Now when you click on the ‘Get Product2 Instance’ button, you’ll see that the Mfg Date (which is set in the constructor) and the Hash Code are different from the one created on page load. This proves to us that a new instance is created every single time. To make this a singleton, we need to add a type alias for the ContainerControlledLifetimeManager class and then change the type attribute of the lifetime element to singleton. 1: <typeAlias alias="singleton" type="Microsoft.Practices.Unity.ContainerControlledLifetimeManager, Microsoft.Practices.Unity"/> 2: ... 3: <type type="IProduct" mapTo="Product2"> 4: <lifetime type="singleton" /> 5: </type> Running the application now gets me the following output: Click on the button below and you’ll see that the Mfg Date and the Hash code remain unchanged => the unity container is storing the reference the first time it is created and then returns the same instance every time the type needs to be resolved. Digging more deeper into this, Unity provides more than the two lifetime managers. ExternallyControlledLifetimeManager – maintains a weak reference to type mappings and instances. Unity returns the same instance as long as the some code is holding a strong reference to this instance. For this, you need: 1: <typeAlias alias="external" type="Microsoft.Practices.Unity.ExternallyControlledLifetimeManager, Microsoft.Practices.Unity"/> 2: ... 3: <type type="IProduct" mapTo="Product2"> 4: <lifetime type="external" /> 5: </type> PerThreadLifetimeManager – Unity returns a unique instance of an object for each thread – so this effectively is a singleton behavior on a  per-thread basis. 1: <typeAlias alias="perThread" type="Microsoft.Practices.Unity.PerThreadLifetimeManager, Microsoft.Practices.Unity"/> 2: ... 3: <type type="IProduct" mapTo="Product2"> 4: <lifetime type="perThread" /> 5: </type> One thing to note about this is that if you use RegisterInstance method to register an existing object, this instance will be returned for every thread, making this a purely singleton behavior. Needless to say, this type of lifetime management is useful in multi-threaded applications (duh!!). I hope this blog provided some basics on lifetime management of objects resolved in Unity and in the next blog, I’ll talk about Injection. Please see the code used here.

  • SEO: best way to deal with short lifetime URLs?

    - by Mike Norgate
    I am currently in the process of redesigning a job advert site and am trying to put a lot more effort into my SEO. My question is how should I deal with the URLs that point to job adverts when the advert expires. The options I have thought of so far are: Return a 404 error and redirect to a 404 page. Will it have an effect on ranking if there are a lot of URLs that return 404s after only being up for a few weeks? Redirect to job listing page - When the user requests a URL for an advert that has expired just redirect to the main job listing page. Show the advert but tell the user to has closed - Show the advert page but with a notification that the advert has closed. The issue I see with this is that the user will visit the page, see its closed and then leave the site again which would not be good for rankings

  • How to use db4o IObjectContainer in a web application ? (Container lifetime ?)

    - by driis
    I am evaluating db4o for persistence for a ASP .NET MVC project. I am wondering how I should use the IObjectContainer in a web context with regards to object lifetime. As I see it, I can do one of the following: Create the IObjectContainer at application startup and keep the same instance for the entire application lifetime. Create one IObjectContainer per request. Start a server, and get a client IObjectContainer for each database interaction. What are the implications of these options, in terms of performance and concurrency ? Since the database is locked when an IObjectContainer is opened, I am pretty sure that option 2) would get me some problems with concurrency - would this also be the case for option 1 ? As I understand it, if I retrieve an object from an IObjectContainer, it must be saved by the same IObjectContainer instance - in order for db4o to identify it as being the same object. Therefore, If I choose option 3), I would have to retrieve the original object, make the necessary changes (copy data from a modified object), and then store it using the same IObjectContainer. Is this true ?

  • Why is short project lifetime and other situation-specific reasons used to excuse crappy code? [clos

    - by sharptooth
    Every now and then (including on SO) people say things implying that "if the project is short lived you can leave obvious defects there" or "that memory leak only accounts for 100 bytes per whole program lifetime and could be left". Now in my practice I always reuse company-owned code to the greatest extent I can. Like if I need something and I can find it in the company codebase I take it from there and reuse or adapt. This means that any crappy code will be reused as well and I might notice or not notice defects therein. So the defect in some "test we only need for a month" can slip into a proram we ship to customers. And a leak that "only accounted for 100 bytes per lifetime" now could account for 100 bytes 10 times per second in a server application intended to run for months. That's why I don't understand why excuses like that are offered. Is our compamy the only one having a source control? Or are we the only company that requires writing human-readable code? Could anyone shed a light on why people seriously offer such excuses?

    The question is simple: what is lifetime of that functor object that is automatically generated for me by the C++ compiler when I write a lambda-expression? I did a quick search, but couldn't find a satisfactory answer. In particular, if I pass the lambda somewhere, and it gets remembered there, and then I go out of scope, what's going to happen once my lambda is called later and tries to access my stack-allocated, but no longer alive, captured variables? Or does the compiler prevent such situation in some way? Or what?
