Run elevated task at any point of the Azure Rol lifetime.
by Guerrerotook on Apr.30, 2011, under .NET, Azure, wcf
There are two mostly common used for Windows Azure, starting a new 100% .NET project on Windows Azure, or migrate a legacy project to the cloud. Talking from this point legacy project could be the most difficult project of all, because can use COM components during him lifetime. As you may know all the Windows Azure roles are clean machine so it’s means that you need to install manually all your component COM. Normally this issue is solved by placing on the startup node of the Role configuration file, a .cmd file with all the registration of the COM components.
But what happens if during role’s lifetime you need to execute a task elevated? You can’t do that because the hosting process of the worker role and web role is not executing with elevated rights. So we have to find a place where we can execute task with elevated rights, and this places is the roll’s startup node. So what we have to do is have a sentinel program up and running at roll’s startup and make this sentinel program to accept requests to execute process.
So this is exactly what we are going to do, using WCF to open a Windows pipe to enable communication between two different process in the same machine, enabling the process to send message with the necessary information to run this elevated task.
Let’s do it!
Service definition.
Since all we need is a WCF service be exposed on NetNamedPipeBinding, first of all we have to define a service contract with the operation contract we need. In this case we only need one operation, ExecuteTask.
[ServiceContract(Namespace = "http://azure.plainconcepts.com/schemas/04/2011/azure/executionhost")] public interface IExecutionHost { [OperationContract] void ExecuteTask(ProcessTask host); }
Once we define the service contract now is the time to create the service itself, who is responsible to finally execute the tasks.
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)] public class ExecutionHostService : IExecutionHost { public void ExecuteTask(ProcessTask host) { Process process = new Process(); process.StartInfo = host.StartInfo; process.Start(); } }
When we have done this, the next step is host the server itself on the sentinel process that will handle the requests, as we said before we’re going to use the NetNamedPipeBinding.
public class ExecutionHostServiceManager { public ExecutionHostServiceManager() { service = new ExecutionHostService(); ServiceHost host = new ServiceHost(service); string address = "net.pipe://PlainConcepts/Azure/ExecutionHost"; NetNamedPipeBinding binding = new NetNamedPipeBinding(NetNamedPipeSecurityMode.None); host.AddServiceEndpoint(typeof(IExecutionHost), binding, address); // Add a mex endpoint long maxBufferPoolSize = binding.MaxBufferPoolSize; int maxBufferSize = binding.MaxBufferSize; int maxConnections = binding.MaxConnections; long maxReceivedMessageSize = binding.MaxReceivedMessageSize; NetNamedPipeSecurity security = binding.Security; string scheme = binding.Scheme; XmlDictionaryReaderQuotas readerQuotas = binding.ReaderQuotas; BindingElementCollection bCollection = binding.CreateBindingElements(); HostNameComparisonMode hostNameComparisonMode = binding.HostNameComparisonMode; bool TransactionFlow = binding.TransactionFlow; TransactionProtocol transactionProtocol = binding.TransactionProtocol; EnvelopeVersion envelopeVersion = binding.EnvelopeVersion; TransferMode transferMode = binding.TransferMode; host.Open(); } private ExecutionHostService service; }
And that is!
Now we have to put this together in a console application and wait forever.
class Program { static void Main(string[] args) { new ExecutionHostServiceManager(); Thread.Sleep(Timeout.Infinite); } }
Making call to the service
We now have the service contract, the service definition and the hosting process, now it’s time to define the client and make call to the servicer. Since we’re using WCF we need to define a class that will handle the request to the pipe. To accomplish this it’s necessary to inherit from ClientBase<T>, and T need to the service contract of the service.
public class ExecutionHostClient : ClientBase<IExecutionHost> { static ExecutionHostClient() { string address = "net.pipe://PlainConcepts/Azure/ExecutionHost"; NetNamedPipeBinding binding = new NetNamedPipeBinding(NetNamedPipeSecurityMode.None); binding.CloseTimeout = TimeSpan.MaxValue; binding.ReceiveTimeout = TimeSpan.MaxValue; binding.SendTimeout = TimeSpan.MaxValue; EndpointAddress endpoint = new EndpointAddress(address); client = new ExecutionHostClient(binding, endpoint); } public ExecutionHostClient(Binding binding, EndpointAddress remoteAddress) : base(binding, remoteAddress) { } public void ExecuteTask(ProcessTask task) { Channel.ExecuteTask(task); } public static void ExecuteRemoteTask(ProcessTask task) { client.ExecuteTask(task); } private static ExecutionHostClient client; }
It’s important to create this proxy with the same configuration of the server, because we’re not using the default Visual Studio code generated proxy, and it’s our responsibility to create the binding and the address of the endpoint.
Invoking services
In this example we are registering COM components by calling the regsvc32.exe in code. We looking for dll files on a known folder of our Windows Azure Solution and invoke the service to make the elevated call.
public class RegisterComHelper { public RegisterComHelper() { } public void Register() { // hay que buscar la localizacion en el servidor de azure de donde estan los ensamblados // como no sabemos donde estan los ficheros tenemos que buscar el modulo // Habitania.RegisterCom.dll que es especifico para este ejemplo // así nos aseguramos que estamos buscando la dll correcta Process current = Process.GetCurrentProcess(); var found = (from p in current.Modules.Cast<ProcessModule>().ToList() where p.ModuleName == "PlainConcepts.Azure.WorkerRoleDemo.dll" select p).FirstOrDefault(); if (found != null) { // a partir de la locacion del modulo cargada por el proceso // somos capaces de encontrar la informacion del directorio y buscar // la carpeta dlls que contiene la lista de dlls que queremos registar string directoryLocation = Path.GetDirectoryName(found.FileName); string dllPath = Path.Combine(directoryLocation, "V3COM30"); string[] files = Directory.GetFiles(dllPath); foreach (var item in files) { if (item.EndsWith(".dll")) RegisterComObject(item); } dllPath = Path.Combine(directoryLocation, "V3COM"); files = Directory.GetFiles(dllPath); foreach (var item in files) { if (item.EndsWith(".dll")) RegisterComObject(item); } } } private void RegisterComObject(string filePath) { ProcessStartInfo info = new ProcessStartInfo(); info.FileName = Path.Combine( Environment.GetFolderPath(Environment.SpecialFolder.System), "regsvr32.exe"); info.Arguments = string.Format("/i {0}", filePath); info.UseShellExecute = false; ExecutionHostClient.ExecuteRemoteTask(new ProcessTask() { StartInfo = info }); } }
This way of invoking task on Windows Azure seems a little bit complicated, but once is done can be super flexible and permit to extend this demo with custom task and background tasks.

How to access to Keyboard in XNA for Windows Phone 7
by Guerrerotook on Jul.17, 2010, under Windows Phone 7
One of the great thinks about developing on XNA is that you have access to low level graphics to draw your sprites and your 3d mesh, but sometimes you need some high level component to provide some functionality to the user like for example a keyboard.
If you plan the user on Windows Phone 7 to type the name to start a new game you need to create your own keyboard and textbox support. This can be a little bit hard, so that why Microsoft include a simple API to show a Task in the Phone in order the user write some text and return this string back to you.
Guide.BeginShowKeyboardInput(
PlayerIndex.One,
"You Win",
"Insert your name",
"",
new AsyncCallback(OnEndShowKeyboardInput),
null);
With this code you are invoking the Keyboard Task, you need to keep in mind that your application will be deactivated and If you have code there will be executed, once the user finish to type the name and tap on accept button will return back to your application.
private void OnEndShowKeyboardInput(IAsyncResult result) { name = Guide.EndShowKeyboardInput(result); }
Here is where you get the string that the user typed.
You can download simple demo showing this functionality from here.

Azure worker role throw a FileLoadException on load
by Guerrerotook on May.11, 2010, under Azure, Debugging
I’m working now on a Smooth Streaming Silverlight player for the world cup and we using Azure to host some services for the player. Recently I started the development of all those services on a Web project and when I’m trying to run the project inside the Azure Simulation Environment the web role throw me a FileLoadException.
[runtime] Role entrypoint could not be created: System.IO.FileLoadException: Could not load file or assembly 'Microsoft.Silverlight.MediaPlayer.Web, Version=1.0.0.0, Culture=neutral, PublicKeyToken=a10dc7bdece43c5c' or one of its dependencies.

I double check that my local assembly Microsoft.Silverlight.MediaPlayer.Web.dll is there and have enough permission to read and load it. Also I enabled Fusion Log to catch the assembly fail load but I can’t find any references to my assembly… so I decided it’s time to WinDBG.

Detecting memory issues with Silverlight
by Guerrerotook on Apr.30, 2010, under Debugging, Silverlight
Hi all!
Today we’re going to talking about a memory leak issue found in Silverlight 4 and report on Silverlight’s forum by tsheflin As you know Silverlight is a .NET technology, so it’s mean you can use C# or Visual Basic to build your Silverlight’s applications and you have all the goodness of .NET, automatic memory management, garbage collector, type safety and so on.
But sometimes something goes wrong and we found that there are memory leaks on a dot net application; Silverlight is not free about this issues. So we’re going to identify how to find this memory issues with WinDBG and sos for Silverlight.
I’m going to use the same example provided by the user of the Silverlight.net forum. You can download from here.
First of all we need to build and run our application in release mode, this is important because there are a few differences between debug and release mode, then run the application without debugging and now its WinDBG time!
If your browser is Windows Internet Explorer 8 and you running Windows 7 or Vista, you may know that IE runs each tab in a separate process so you need to identify first witch process is running your code, in my example I found my process is 7958.
With WinDBG open (you can download from here http://www.microsoft.com/whdc/devtools/debugging/installx86.mspx#a), go to File -> Attach to process (F6), and select your process id (in my machine is 7958), immediately appear output window with all the basic debug information. Since our application is a managed application and WinDBG is designed to debug native application we need a debugger extension to debug managed application. What we need is SOS (Son of Strike). SOS is located in my machine here C:\Program Files (x86)\Microsoft Silverlight\4.0.50401.0\sos.dll for every version of Silverlight there is a SOS version, so depending the Silverlight version you’re debugging you need to load this extension.
Once we have this file, SOS can be loaded writing
.load C:\Program Files (x86)\Microsoft Silverlight\4.0.50401.0\sos.dll
And now we have all the power of SOS in WinDBG.
Next we need to find a valid memory address for our type SilverlightVisualTreeRemovalFail.SilverlightControl1 so we’re going to use !dumpheap command to dump all heap types and filter by this type writing this:
!dumpheap -type SilverlightVisualTreeRemovalFail.SilverlightControl1 0:005> !dumpheap -type SilverlightVisualTreeRemovalFail.SilverlightControl1 Address MT Size 087aad6c 04a45230 92 087ab460 04a45230 92 087ab6f0 04a45230 92 087ac01c 04a45230 92 087ac710 04a45230 92 087ace04 04a45230 92 087ad4f8 04a45230 92 087adbec 04a45230 92 087ae2e0 04a45230 92 087ae9d4 04a45230 92 087af0c8 04a45230 92 087af7bc 04a45230 92 087afeb0 04a45230 92 087b05a4 04a45230 92 087b0c98 04a45230 92 087b138c 04a45230 92 087b1a80 04a45230 92 087b2174 04a45230 92 087b2868 04a45230 92 087b2f5c 04a45230 92 087b3650 04a45230 92 087b3d44 04a45230 92 087b4438 04a45230 92 087b4b2c 04a45230 92 087b5220 04a45230 92 087b5914 04a45230 92 087b6008 04a45230 92 087b66fc 04a45230 92 087b6df0 04a45230 92 087b74e4 04a45230 92 087b7bd8 04a45230 92 087b82cc 04a45230 92 087b89c0 04a45230 92 087b90b4 04a45230 92 087b97a8 04a45230 92 087b9e9c 04a45230 92 087ba590 04a45230 92 087bac84 04a45230 92 087bb378 04a45230 92 087bba6c 04a45230 92 087bc160 04a45230 92 087bc854 04a45230 92 087bcf48 04a45230 92 087bd63c 04a45230 92 087bdd30 04a45230 92 087be424 04a45230 92 087beb18 04a45230 92 087bf20c 04a45230 92 087bf900 04a45230 92 087bfff4 04a45230 92
In output window we found some addresses for this type, selecting one 087b1a80 we need to find witch object is referencing this object (this is what is causing not to be recoleted) writing this:
!gcroot 087b1a80
0:005> !gcroot 087b1a80 Note: Roots found on stacks may be false positives. Run "!help gcroot" for more info. Scan Thread 5 OSTHread 10e8 Scan Thread 22 OSTHread 1f8 Scan Thread 23 OSTHread 1588 DOMAIN(07134BE0):HANDLE(Pinned):4a912f8:Root: 09784260(System.Object[])-> 08796c78(System.Collections.Generic.Dictionary`2[[System.IntPtr, mscorlib],[System.Object, mscorlib]])-> 09788260(System.Collections.Generic.Dictionary`2+Entry[[System.IntPtr, mscorlib],[System.Object, mscorlib]][])-> 087b1e90(System.Windows.Controls.ControlTemplate)-> 087b1a80(SilverlightVisualTreeRemovalFail.SilverlightControl1)
We found that this object (087b1a80) is reference by other object and on the top of the list there is a HANDLE(Pinned):4a912f8 so its means that the garbage collection will always found a path to this object causing not to be garbage collected.
Now we identify the problem, but for now we can’t do anything because this is a Microsoft issue, because Microsoft’s code is referencing our control so we can’t fix this by ourselves. If this code is from us what we need to is simply remove references from this dictionary and then the control will be garbage collected.
We can also dump all the heap to a file and then open this file with CLRProfiler, type !traverseheap and file output and the open with CLRProfiler.
All the best.

Silverlight player is now Microsfot’s Case Study
by Guerrerotook on Apr.29, 2010, under Silverlight
Hi all!
Working as a developer sometimes is hard; clients are always busy and want their software delivered on time! So it’s exiting when you discover that software you made is a success for your client, so here we are.
Few months ago I started a Silverlight video player for Spanish’s national broadcaster Tele5. They want more flexibility to deliver their content to users. So we help them to build a Silverlight powered video player. This was before MEF (Managed Extensibility Framework) exists, so I implement by myself a plug-in arquitecture for Silverlight with some similar concepts as MEF have.
So, what’s this post about? To tell everyone that this project is now a Microsoft Case Studies and you can read all about this exciting project on Microsoft’s web page. Of course you can enjoy the player itself on Tele5’s news.

Concurrent programming and Managed Extensibilty Framework

Writing high performance parallel code with monitors
by Guerrerotook on Nov.29, 2009, under .NET, Concurrent
Multithread application is going to be next issue for developer, and we need to be ready for this big change. In .NET Framework 4, Microsoft introduced Task Parallel Library, a set of API that helps developer creating concurrent applications. That’s means that you don’t have to take care about all those concurrent issues anymore, its mean now is easier to create concurrent code.
Currently I’m working in an application that makes a hard use of all TLP code. What I do is creating a lot of Task objects to manage the executing of a set of rules that have to be executed for each Uri. I maintain a list with all the Task object to observer during time, how much Task are now running, and make some statistics about software speed.
This means I have UI, created in WPF that need to communicate with this code to get all running Task and display this information in the UI. Since I’m using a simple List<Task> to get a reference to all task created during my application execution, I need a way to lock and add Tasks to this list, enumerate this list and remove Tasks. But I want this lock to be shortest one and only lock to important operations like add and remove items when Task are finished.
So I have two important operations, create new Task and add to this list, and when the Task is finish removes this Task from the list, and for that I need to wait if the lock is acquired by other thread, because multiple Tasks can finish at the same time.
Creating task is done by a timer inside my application and this timer is set to run each second to check if the running Task in the system are lower that minimum Task running. If this is true is the moment create more Task and add to the list. Since this timer is executed every second I’ll need to lock my list of Task, do my work and then release the lock. I’m using the list as lock object. But this timer can wait more than one second until the lock is released, because other Task are now executing and finish work and remove items from my list, so It’s mean I’m creating a classic convoy in my application. Every time my timer method is executed and wait until the lock to release, this time is bigger that timer elapsed time, so I need a way to wait only a certain period of time.
What I do in this method is using the new API for Monitor in .NET 4 that attempts, for a number of milliseconds, to acquire an exclusive lock and atomically set a value that indicates whether the lock was taken or not. In my case I set these milliseconds in 400, because in this method I do more stuff than work with my list of Task. If the lock is bigger than 400ms the lock will not be acquired.
bool taken = false; try { Monitor.TryEnter(task, 400, ref taken); if (taken) { if (!cancelationTokenSource.IsCancellationRequested) { var count = (from p in task where p.Status == TaskStatus.Running || p.Status == TaskStatus.WaitingToRun select p).Count(); } } } finally { if (taken) { Monitor.Exit(task); } }
As you can see in this code I’m calling Monitor.TryEnter inside a try/catch block, and then in the finally block if the lock was acquired I release the lock by calling Monitor.Exit. I do in that way because if during the execution of my code an exception is throw, the call to Monitor.Exit at the end of the code will not be executed anymore, causing that I have a lock that will never be released.
My other scenario is when I want to get all Task to count how much task are now running, I do the same inside get accessor of the property Task, but in this case I only wait for 250ms instead of 400ms. If the lock is acquired I copy the collection into a new list and there I can safety count how much Task are running.
public List<Task> Tasks { get { bool taken = false; List<Task> list = null; try { Monitor.TryEnter(task, 250, ref taken); if (taken) { list = new List<Task>(task.ToArray()); } } finally { if (taken) { Monitor.Exit(task); } } return list; } }
This solution is simple and keeps your code with the lowest contention rate giving boots to those important operations that need to wait until the lock is released.
I could also create a wrap over List<T> list using ReaderWriterLockSlim to control read and write operation during lock, but ReaderWriterLockSlim is focus on multiple readers and only one writer, and I my application I have multiple writers and only one reader.
All the best.
Luis.
Dealing with Heap Corruptions in .NET
by Guerrerotook on Nov.16, 2009, under Debugging, WinDBG
One of the best features of the .NET Framework is automatic memory management, its means you don’t need to worry about memory leaks, memory corruptions and other memory issues. But this is not always true, I want to show an issue I having now with a .NET 4 application.
As may know clr have a managed heap, and this heap contains all the object you’ve creating across your code, and the garbage collector take care on dispose, free memory and sort all the content of the heap. There are some useful commands to show the content of the managed heap with SOS (Son of strike) WinDBG’s extension, one of them is !dumpheap.
During the execution of my application randomly throw me a System.ExecutionEngineException. As you can imagine this is a fatal error in the runtime itself, not in my code so there is no chance for catch the exception and my application will close.

As you can see on this output from WinDBG at thread 44 the exception object is (GC) (Threadpool Worker) System.ExecutionEngineException (0000000002871228) and the address at the end is my System.ExecutionEngineException.
In my managed stack my last frame is a System.Text.StringBuilder.ToString() so assuming that I’m creating memory from there. If we check native stack this thread was doing a garbage collection.
The sequence is: FramedAllocateString -> GCHeap::Alloc -> gc_heap::try_allocate_more_space -> GCHeap::GarbageCollectGeneration -> gc_heap::garbage_collect -> :gc_heap::gc1
At this point we truly know that the runtime is trying to allocate memory for that string, but since there is no more memory available the runtime raise a garbage collection and there is where the runtime found that there is a corruption in the manage heap.
There is also another useful command in WinDBG !verifyheap is a diagnostic tool that checks the garbage collected heap for signs of corruption on managed heap.
0:044> !verifyheap -verify will only produce output if there are errors in the heap The garbage collector data structures are not in a valid state for traversal. It is either in the "plan phase," where objects are being moved around, or we are at the initialization or shutdown of the gc heap. Commands related to displaying, finding or traversing objects as well as gc heap segments may not work properly. !dumpheap and !verifyheap may incorrectly complain of heap consistency errors. object 0000000006fb6ec8: bad member 0000000008f1b750 at 0000000006fb6ef8 curr_object: 0000000006fb6ec8 Last good object: 0000000006fb6e50 ----------------
The !verifyheap command is telling us that in that precise moment were occurring a garbage collection and all the structures are not in a valid state, but at the end of the report there is an object that have a bad member, this object is a System.IO.StreamReader and the bad member is System.Char[] 0000000008f1b750 charBuffer.

What we can do with this problem?
Since the exception is part of the runtime there is now way to fix it, so the only option is call Microsoft support service to tell that you have a problem with memory corruptions on .net framework.
Happy debugging. Luis.

Hi everyone! This is my first post, actually is not *really* my first post, because I have another blog but it’s in Spanish.
What is this blog about?
I’m a .NET developer, currently I work in Plain Concepts, a Spanish company but we have offices in London and there is where I work. As part of my job I develop solutions in .net technologies, deliver some training and consulter.
I’ll write about stuff like .NET 4, User Experience (UX), Windows Presentation Foundation (WPF), Silverlight, Microsoft Surface, Task Parallel Library, Advanced Debugging, profiling and so on, so keep tuner.
Luis.
