  • How can I *prevent* Apache2 from setting the Content-Type header?

    - by Norm
    I have a CGI script that prints the following on stdout: print "Status: 302 Redirect\n"; print "Server: Apache-Coyote/1.1\n"; print "Location: $redirect\n"; print "Content-Length: 0\n"; print "Date: $date\n\n"; Where $redirect and $date are reasonable values. What Apache2 actually sends also includes a Content-Type: header (text/plain). I've commented out the DefaultType in the server configuration file. I'm trying to debug a downstream problem that arises when no Content-Type: header is sent. So what magic incantation do I have to perform to prevent Apache2 from adding the content type header?

  • Solution to Jira web service getWorklogs method error: Object of type System.Xml.XmlNode[] cannot be stored in an array of this type

    - by DigiMortal
    When using Jira web service methods that operate on work logs you may get the following error when running your .NET application: Object of type System.Xml.XmlNode[] cannot be stored in an array of this type. In this posting I will show you solution to this problem. I don’t want to go to deep in details about this problem. I think it’s enough for this posting to mention that this problem is related to one small conflict between .NET web service support and Axis. Of course, Jira team is trying to solve it but until this problem is solved you can use solution provided here. There is good solution to this problem given by Jira forum user Kostadin. You can find it from Jira forum thread RemoteWorkLog serialization from Soap Service in C#. Solution is simple – you have to use SOAP extension class to replace new class names with old ones that .NET found from WSDL. Here is the code by Kostadin. public class JiraSoapExtensions : SoapExtension {     private Stream _streamIn;     private Stream _streamOut;       public override void ProcessMessage(SoapMessage message)     {         string messageAsString;         StreamReader reader;         StreamWriter writer;           switch (message.Stage)         {             case SoapMessageStage.BeforeSerialize:                 break;             case SoapMessageStage.AfterDeserialize:                 break;             case SoapMessageStage.BeforeDeserialize:                 reader = new StreamReader(_streamOut);                 writer = new StreamWriter(_streamIn);                 messageAsString = reader.ReadToEnd();                 switch (message.MethodInfo.Name)                 {                     case "getWorklogs":                     case "addWorklogWithNewRemainingEstimate":                     case "addWorklogAndAutoAdjustRemainingEstimate":                     case "addWorklogAndRetainRemainingEstimate":                         messageAsString = messageAsString.                             .Replace("RemoteWorklogImpl", "RemoteWorklog")                             .Replace("service", "beans");                         break;                 }                 writer.Write(messageAsString);                 writer.Flush();                 _streamIn.Position = 0;                 break;             case SoapMessageStage.AfterSerialize:                 _streamIn.Position = 0;                 reader = new StreamReader(_streamIn);                 writer = new StreamWriter(_streamOut);                 messageAsString = reader.ReadToEnd();                 writer.Write(messageAsString);                 writer.Flush(); break;         }     }       public override Stream ChainStream(Stream stream)     {         _streamOut = stream;         _streamIn = new MemoryStream();         return _streamIn;     }       public override object GetInitializer(Type type)     {         return GetType();     }       public override object GetInitializer(LogicalMethodInfo info,         SoapExtensionAttribute attribute)     {         return null;     }       public override void Initialize(object initializer)     {     } } To get this extension work with Jira web service you have to add the following block to your application configuration file (under system.web section). <webServices>   <soapExtensionTypes>    <add type="JiraStudioExperiments.JiraSoapExtensions,JiraStudioExperiments"           priority="1"/>   </soapExtensionTypes> </webServices> Weird thing is that after successfully using this extension and disabling it everything still works.

  • How to associate all file types within Wine with its corresponding native application?

    - by MestreLion
    This is easily done for a single file type, as answered in How to associate a file type within Wine with a native application?, by creating a .reg for the desired filetype. But this is for AVI only. I use some wine apps (uTorrent, Soulseek, Eudora, to name a few) that can launch a wide range of files. Email attachments, for example, can be JPG, DOC, PDF, PPS... its impossible (and not desirable) to track down all possible file types that one may receive in an email or download in a torrent. So I neeed a solution to be more generic and broad. I need the file association to honor whatever native app is currently configured. And I want this to be done for all file types configured in my system. I've already figured out how to make the solution generic. Simply replacing the launched app in .reg for winebrowser, like this: [HKEY_CLASSES_ROOT\.pdf] @="PDFfile" "Content Type"="application/pdf" [HKEY_CLASSES_ROOT\PDFfile\Shell\Open\command] @="C:\\windows\\system32\\winebrowser.exe \"%1\"" Ive tested this and it works correctly. Since winebrowser uses xdg-open as a backend, and converts my windows path to a Unix one, the correct (Linux) app is launched. So I need a "batch" updater to wine's registry, sort of a wine-update-associations script that I can run whenever a new app is installed. Maybe a tool that can: List all Mime Types types in my system that have a default, installed app associated Extract all the needed info (glob, mime type, etc) Generate the .REG file in the above format The tricky part is: i've searched a LOT to find info about how association is done in Ubuntu 10.10 onwards, and documentation is scarce and confusing, to say the least. Freedesktop.org has no complete spec, and even Gnome docs are obsolete. So far I've gathered 4 files that contain association info, but im clueless on which (or why) to use, or how to use them to generate the .reg file: ~/.local/share/applications/mimeapps.list ~/.local/share/applications/miminfo.cache /usr/share/applications/miminfo.cache /etc/gnome/defaults.list Any help, script or explanation would be greatly appreciated! Thanks!

  • Templated << friend not working when in interrelationship with other templated union types

    - by Dwight
    While working on my basic vector library, I've been trying to use a nice syntax for swizzle-based printing. The problem occurs when attempting to print a swizzle of a different dimension than the vector in question. In GCC 4.0, I originally had the friend << overloaded functions (with a body, even though it duplicated code) for every dimension in each vector, which caused the code to work, even if the non-native dimension code never actually was called. This failed in GCC 4.2. I recently realized (silly me) that only the function declaration was needed, not the body of the code, so I did that. Now I get the same warning on both GCC 4.0 and 4.2: LINE 50 warning: friend declaration 'std::ostream& operator<<(std::ostream&, const VECTOR3<TYPE>&)' declares a non-template function Plus the five identical warnings more for the other function declarations. The below example code shows off exactly what's going on and has all code necessary to reproduce the problem. #include <iostream> // cout, endl #include <sstream> // ostream, ostringstream, string using std::cout; using std::endl; using std::string; using std::ostream; // Predefines template <typename TYPE> union VECTOR2; template <typename TYPE> union VECTOR3; template <typename TYPE> union VECTOR4; typedef VECTOR2<float> vec2; typedef VECTOR3<float> vec3; typedef VECTOR4<float> vec4; template <typename TYPE> union VECTOR2 { private: struct { TYPE x, y; } v; struct s1 { protected: TYPE x, y; }; struct s2 { protected: TYPE x, y; }; struct s3 { protected: TYPE x, y; }; struct s4 { protected: TYPE x, y; }; struct X : s1 { operator TYPE() const { return s1::x; } }; struct XX : s2 { operator VECTOR2<TYPE>() const { return VECTOR2<TYPE>(s2::x, s2::x); } }; struct XXX : s3 { operator VECTOR3<TYPE>() const { return VECTOR3<TYPE>(s3::x, s3::x, s3::x); } }; struct XXXX : s4 { operator VECTOR4<TYPE>() const { return VECTOR4<TYPE>(s4::x, s4::x, s4::x, s4::x); } }; public: VECTOR2() {} VECTOR2(const TYPE& x, const TYPE& y) { v.x = x; v.y = y; } X x; XX xx; XXX xxx; XXXX xxxx; // Overload for cout friend ostream& operator<<(ostream& os, const VECTOR2<TYPE>& toString) { os << "(" << toString.v.x << ", " << toString.v.y << ")"; return os; } friend ostream& operator<<(ostream& os, const VECTOR3<TYPE>& toString); friend ostream& operator<<(ostream& os, const VECTOR4<TYPE>& toString); }; template <typename TYPE> union VECTOR3 { private: struct { TYPE x, y, z; } v; struct s1 { protected: TYPE x, y, z; }; struct s2 { protected: TYPE x, y, z; }; struct s3 { protected: TYPE x, y, z; }; struct s4 { protected: TYPE x, y, z; }; struct X : s1 { operator TYPE() const { return s1::x; } }; struct XX : s2 { operator VECTOR2<TYPE>() const { return VECTOR2<TYPE>(s2::x, s2::x); } }; struct XXX : s3 { operator VECTOR3<TYPE>() const { return VECTOR3<TYPE>(s3::x, s3::x, s3::x); } }; struct XXXX : s4 { operator VECTOR4<TYPE>() const { return VECTOR4<TYPE>(s4::x, s4::x, s4::x, s4::x); } }; public: VECTOR3() {} VECTOR3(const TYPE& x, const TYPE& y, const TYPE& z) { v.x = x; v.y = y; v.z = z; } X x; XX xx; XXX xxx; XXXX xxxx; // Overload for cout friend ostream& operator<<(ostream& os, const VECTOR3<TYPE>& toString) { os << "(" << toString.v.x << ", " << toString.v.y << ", " << toString.v.z << ")"; return os; } friend ostream& operator<<(ostream& os, const VECTOR2<TYPE>& toString); friend ostream& operator<<(ostream& os, const VECTOR4<TYPE>& toString); }; template <typename TYPE> union VECTOR4 { private: struct { TYPE x, y, z, w; } v; struct s1 { protected: TYPE x, y, z, w; }; struct s2 { protected: TYPE x, y, z, w; }; struct s3 { protected: TYPE x, y, z, w; }; struct s4 { protected: TYPE x, y, z, w; }; struct X : s1 { operator TYPE() const { return s1::x; } }; struct XX : s2 { operator VECTOR2<TYPE>() const { return VECTOR2<TYPE>(s2::x, s2::x); } }; struct XXX : s3 { operator VECTOR3<TYPE>() const { return VECTOR3<TYPE>(s3::x, s3::x, s3::x); } }; struct XXXX : s4 { operator VECTOR4<TYPE>() const { return VECTOR4<TYPE>(s4::x, s4::x, s4::x, s4::x); } }; public: VECTOR4() {} VECTOR4(const TYPE& x, const TYPE& y, const TYPE& z, const TYPE& w) { v.x = x; v.y = y; v.z = z; v.w = w; } X x; XX xx; XXX xxx; XXXX xxxx; // Overload for cout friend ostream& operator<<(ostream& os, const VECTOR4& toString) { os << "(" << toString.v.x << ", " << toString.v.y << ", " << toString.v.z << ", " << toString.v.w << ")"; return os; } friend ostream& operator<<(ostream& os, const VECTOR2<TYPE>& toString); friend ostream& operator<<(ostream& os, const VECTOR3<TYPE>& toString); }; // Test code int main (int argc, char * const argv[]) { vec2 my2dVector(1, 2); cout << my2dVector.x << endl; cout << my2dVector.xx << endl; cout << my2dVector.xxx << endl; cout << my2dVector.xxxx << endl; vec3 my3dVector(3, 4, 5); cout << my3dVector.x << endl; cout << my3dVector.xx << endl; cout << my3dVector.xxx << endl; cout << my3dVector.xxxx << endl; vec4 my4dVector(6, 7, 8, 9); cout << my4dVector.x << endl; cout << my4dVector.xx << endl; cout << my4dVector.xxx << endl; cout << my4dVector.xxxx << endl; return 0; } The code WORKS and produces the correct output, but I prefer warning free code whenever possible. I followed the advice the compiler gave me (summarized here and described by forums and StackOverflow as the answer to this warning) and added the two things that supposedly tells the compiler what's going on. That is, I added the function definitions as non-friends after the predefinitions of the templated unions: template <typename TYPE> ostream& operator<<(ostream& os, const VECTOR2<TYPE>& toString); template <typename TYPE> ostream& operator<<(ostream& os, const VECTOR3<TYPE>& toString); template <typename TYPE> ostream& operator<<(ostream& os, const VECTOR4<TYPE>& toString); And, to each friend function that causes the issue, I added the <> after the function name, such as for VECTOR2's case: friend ostream& operator<< <> (ostream& os, const VECTOR3<TYPE>& toString); friend ostream& operator<< <> (ostream& os, const VECTOR4<TYPE>& toString); However, doing so leads to errors, such as: LINE 139: error: no match for 'operator<<' in 'std::cout << my2dVector.VECTOR2<float>::xxx' What's going on? Is it something related to how these templated union class-like structures are interrelated, or is it due to the unions themselves? Update After rethinking the issues involved and listening to the various suggestions of Potatoswatter, I found the final solution. Unlike just about every single cout overload example on the internet, I don't need access to the private member information, but can use the public interface to do what I wish. So, I make a non-friend overload functions that are inline for the swizzle parts that call the real friend overload functions. This bypasses the issues the compiler has with templated friend functions. I've added to the latest version of my project. It now works on both versions of GCC I tried with no warnings. The code in question looks like this: template <typename SWIZZLE> inline typename EnableIf< Is2D< typename SWIZZLE::PARENT >, ostream >::type& operator<<(ostream& os, const SWIZZLE& printVector) { os << (typename SWIZZLE::PARENT(printVector)); return os; } template <typename SWIZZLE> inline typename EnableIf< Is3D< typename SWIZZLE::PARENT >, ostream >::type& operator<<(ostream& os, const SWIZZLE& printVector) { os << (typename SWIZZLE::PARENT(printVector)); return os; } template <typename SWIZZLE> inline typename EnableIf< Is4D< typename SWIZZLE::PARENT >, ostream >::type& operator<<(ostream& os, const SWIZZLE& printVector) { os << (typename SWIZZLE::PARENT(printVector)); return os; }

  • How can I pass a Visual Studio project's assembly version to another project for use in a post-build

    - by Coder7862396
    I have a solution with 2 projects: My Application 1.2.54 (C# WinForms) My Application Setup 1.0.0.0 (WiX Setup) I would like to add a post-build event to the WiX Setup project to run a batch file and pass it a command line parameter of My Application's assembly version number. The code may look something like this: CALL MyBatchFile.bat "$(fileVersion.ProductVersion($(var.My Application.TargetPath)))" But this results in the following error: Unhandled Exception:The expression """.My Application" cannot be evaluated. Method 'System.String.My Application' not found. C:\My Application\My Application Setup\My Application Setup.wixproj Error: The expression """.My Application" cannot be evaluated. Method 'System.String.My Application' not found. C:\My Application\My Application Setup\My Application Setup.wixproj I would like to be able to pass "1.2.54" to MyBatchFile.bat somehow.

  • Can you do a struts2 action redirect using POST instead of GET?

    - by Andy Pryor
    <action name="actionA" class="com.company.Someaction"> <result name="success" type="redirect-action"> <param name="actionName">OtherActionparam> <param name="paramA">${someParams}</param> <param name="paramB">${someParams}</param> <param name="aBoatLoadOfOtherParams">${aBoatLoadOfOtherParams}</param> </result> </action> In the above action map, I am redirecting from SomeAction to OtherAction. I am having issues, because unfortunately I need to pass a large amount of data between the two actions. IE7 will only allow GET requests to be like 2k, so its blowing up when I'm just over that limit when the response calls a get request to the other action. Is it possible for me to set this redirect, to end up with a POST being called to the other action?

  • Send JSON object via GET and POST without having to wrapping it in another object literal, and manag

    - by Kucebe
    My site does some short ajax call in JSON format, using jQuery. At client-side i'd like to send object just passing it in ajax function, without being forced to wrap it in an object literal like this: {'person' : person}. For the same reasons, at server-side i'd like to manage objects without the binding of $_GET['person'] or $_POST['person']. For example: var person = { 'name' : 'John', 'lastName' : 'Doe', 'age' : 32, 'married' : true } sendAjaxRequest(person); in php, using: $person = json_decode(file_get_contents("php://input")); i can get easily the object, but only with POST format, not in GET. Any suggestions?

  • How do I post to a webservice and display the returned Response in MVC3 Razor Application?

    - by DavieDave
    I have need to call a webservice from an HTML helper extension I created (combinbation of Action and Image) and placed in the view as follows @Html.ActionImage("CallService", new { number = ViewBag.number, code = ViewBag.code, account = ViewBag.account, amount = ViewBag.amount }, "~/Content/sb_200x61.png", "Start the Process") I am making the action call and it calls the service and returns a string of the html response, but it doesn't look right. I am using the typical HttpWebRequest to do the POST Action in C# code. Here is the controller action code: public MvcHtmlString CallService(string number, string code, string account, decimal? amount) { string response = MyService.ServiceLayer.ClassName.callService(number, code, account, Convert.ToDecimal(amount); MvcHtmlString mstring = new MvcHtmlString(response); return mstring; } When it returns the string back it's looking like the all styling and js is removed. It that due to MvcHtmlString? Is there a better way to do this? Redirect somehow ?

  • How do I identify where the POST data sent to a PHP script came from?

    - by Mike Turley
    I have a ton of data collection forms on my website, and I wrote a PHP script to handle all the data. All the forms have that one script as their action, and POST as the method. The handler emails a copy of the data to me, and I'd like for the emails I get to contain the URL of the form where they originated. Is there any way in PHP to get the url of the form which was submitted to the script? Or do I have to add an extra hidden field in every form with its URL?

  • TFS 2010 Build Custom Activity for Merging Assemblies

    - by Jakob Ehn
    *** The sample build process template discussed in this post is available for download from here: http://cid-ee034c9f620cd58d.office.live.com/self.aspx/BlogSamples/ILMerge.xaml ***   In my previous post I talked about library builds that we use to build and replicate dependencies between applications in TFS. This is typically used for common libraries and tools that several other application need to reference. When the libraries grow in size over time, so does the number of assemblies. So all solutions that uses the common library must reference all the necessary assemblies that they need, and if we for example do a refactoring and extract some code into a new assembly, all the clients must update their references to reflect these changes, otherwise it won’t compile. To improve on this, we use a tool from Microsoft Research called ILMerge (Download from here). It can be used to merge several assemblies into one assembly that contains all types. If you haven’t used this tool before, you should check it out. Previously I have implemented this in builds using a simple batch file that contains the full command, something like this: "%ProgramFiles(x86)%\microsoft\ilmerge\ilmerge.exe" /target:library /attr:ClassLibrary1.bl.dll /out:MyNewLibrary.dll ClassLibrary1.dll ClassLibrar2.dll ClassLibrary3.dll This merges 3 assemblies (ClassLibrary1, 2 and 3) into a new assembly called MyNewLibrary.dll. It will copy the attributes (file version, product version etc..) from ClassLibrary1.dll, using the /attr switch. For more info on ILMerge command line tool, see the above link. This approach works, but requires a little bit too much knowledge for the developers creating builds, therefor I have implemented a custom activity that wraps the use of ILMerge. This makes it much simpler to setup a new build definition and have the build automatically do the merging. The usage of the activity is then implemented as part of the Library Build process template mentioned in the previous post. For this article I have just created a simple build process template that only performs the ILMerge operation.   Below is the code for the custom activity. To make it compile, you need to reference the ILMerge.exe assembly. /// <summary> /// Activity for merging a list of assembies into one, using ILMerge /// </summary> public sealed class ILMergeActivity : BaseCodeActivity { /// <summary> /// A list of file paths to the assemblies that should be merged /// </summary> [RequiredArgument] public InArgument<IEnumerable<string>> InputAssemblies { get; set; } /// <summary> /// Full path to the generated assembly /// </summary> [RequiredArgument] public InArgument<string> OutputFile { get; set; } /// <summary> /// Which input assembly that the attibutes for the generated assembly should be copied from. /// Optional. If not specified, the first input assembly will be used /// </summary> public InArgument<string> AttributeFile { get; set; } /// <summary> /// Kind of assembly to generate, dll or exe /// </summary> public InArgument<TargetKindEnum> TargetKind { get; set; } // If your activity returns a value, derive from CodeActivity<TResult> // and return the value from the Execute method. protected override void Execute(CodeActivityContext context) { string message = InputAssemblies.Get(context).Aggregate("", (current, assembly) => current + (assembly + " ")); TrackMessage(context, "Merging " + message + " into " + OutputFile.Get(context)); ILMerge m = new ILMerge(); m.SetInputAssemblies(InputAssemblies.Get(context).ToArray()); m.TargetKind = TargetKind.Get(context) == TargetKindEnum.Dll ? ILMerge.Kind.Dll : ILMerge.Kind.Exe; m.OutputFile = OutputFile.Get(context); m.AttributeFile = !String.IsNullOrEmpty(AttributeFile.Get(context)) ? AttributeFile.Get(context) : InputAssemblies.Get(context).First(); m.SetTargetPlatform(RuntimeEnvironment.GetSystemVersion().Substring(0,2), RuntimeEnvironment.GetRuntimeDirectory()); m.Merge(); TrackMessage(context, "Generated " + m.OutputFile); } } [Browsable(true)] public enum TargetKindEnum { Dll, Exe } NB: The activity inherits from a BaseCodeActivity class which is an internal helper class which contains some methods and properties useful for moste custom activities. In this case, it uses the TrackeMessage method for writing to the build log. You either need to remove the TrackMessage method calls, or implement this yourself (which is not very hard… ) The custom activity has the following input arguments: InputAssemblies A list with the (full) paths to the assemblies to merge OutputFile The name of the resulting merged assembly AttributeFile Which assembly to use as the template for the attribute of the merged assembly. This argument is optional and if left blank, the first assembly in the input list is used TargetKind Decides what type of assembly to create, can be either a dll or an exe Of course, there are more switches to the ILMerge.exe, and these can be exposed as input arguments as well if you need it. To show how the custom activity can be used, I have attached a build process template (see link at the top of this post) that merges the output of the projects being built (CommonLibrary.dll and CommonLibrary2.dll) into a merged assembly (NewLibrary.dll). The build process template has the following custom process parameters:   The Assemblies To Merge argument is passed into a FindMatchingFiles activity to located all assemblies that are located in the BinariesDirectory folder after the compilation has been performed by Team Build. Here is the complete sequence of activities that performs the merge operation. It is located at the end of the Try, Compile, Test and Associate… sequence: It splits the AssembliesToMerge parameter and appends the full path (using the BinariesDirectory variable) and then enumerates the matching files using the FindMatchingFiles activity. When running the build, you can see that it merges two assemblies into a new one:     And the merged assembly (and associated pdb file) is copied to the drop location together with the rest of the assemblies:

    I’ve been absent from blogging for awhile. Part of it is due to the ultimate inertia of my life.

  • Post build events using ROBOCOPY instead of XCOPY

    - by Vizioz Limited
    I don't know about you, but for a long time I have used XCOPY statements in my Visual Studio post build events to copy my Umbraco files from the project folders to the local version of the website associated with the project.For the last few months we have been building a website framework for a client, who has subsequently sold the site to 5 clients, each with a different skin and some variations in their functional requirements.So, we now have a single source solutions, that builds and copies the site files into 5 seperate local websites, which enables us to easily test them all, what we had found was that this process was starting to slow up our build process and was reaching 30-45 seconds on a high spec Quad core machine (and slower on others)Today I asked Colin to create seperate Solution Configurations within Visual Studio so that while we were developing we could target a single site, and when we wanted to test all sites, we could target "ALL" and the Post Build script would then copy the files to all sites.This worked well, and with a couple of other optimisations, our build was now taking about 10 seconds for a single site.Then Colin came across ROBOCOPY and suggested that maybe this would be a suitable alternative to XCOPY, well, I had not heard of it.. (shock horror some of you shout, some I am sure like me, are also wondering what it is!)ROBOCOPY is new in Windows Vista & Windows 7 (you can also download it for XP & Windows 2003) and it has a lot of additional features, the two that were most interesting to us were:/MIR = Mirror a folder tree/XD = Exclude Directories/NP = No Progress (i.e. it does not give you a chart of it's results, which just fills up your Output window!)So, we set about implementing ROBOCOPY, we decided to use the /MIR switch on all folders that we knew were always stored in our project folders:- images- css- masterpages- xsltAnd for other files we just used the straight robocopy functionality.We also decided to exclude all the .SVN directories using the /XD switch and finally we added the /NP switch as mentioned above.The beauty of all of this, is the /MIR functionality, as this means that only files that have changed will be copied across which greatly speeds up the process, especially on the images folders which previously copied across on every build, now, if we add a new image to the project it will be copied across automatically and then never again, unless we change it of course!The build time now for all sites is approximately 4 seconds and for a single site, 2 seconds, I would highly recommend the time to make the same optimisations to your build processes if you have not done so already.

  • SQL SERVER – PREEMPTIVE and Non-PREEMPTIVE – Wait Type – Day 19 of 28

    - by pinaldave
    In this blog post, we are going to talk about a very interesting subject. I often get questions related to SQL Server 2008 Book-Online about various Preemptive wait types. I got a few questions asking what these wait types are and how they could be interpreted. To get current wait types of the system, you can read this article and run the script: SQL SERVER – DMV – sys.dm_os_waiting_tasks and sys.dm_exec_requests – Wait Type – Day 4 of 28. Before we continue understanding them, let us study first what PREEMPTIVE and Non-PREEMPTIVE waits in SQL Server mean. PREEMPTIVE: Simply put, this wait means non-cooperative. While SQL Server is executing a task, the Operating System (OS) interrupts it. This leads to SQL Server to involuntarily give up the execution for other higher priority tasks. This is not good for SQL Server as it is a particular external process which makes SQL Server to yield. This kind of wait can reduce the performance drastically and needs to be investigated properly. Non-PREEMPTIVE: In simple terms, this wait means cooperative. SQL Server manages the scheduling of the threads. When SQL Server manages the scheduling instead of the OS, it makes sure its own priority. In this case, SQL Server decides the priority and one thread yields to another thread voluntarily. In the earlier version of SQL Server, there was no preemptive wait types mentioned and the associated task status with them was marked as suspended. In SQL Server 2005, preemptive wait types were not listed as well, but their associated task status was marked as running. In SQL Server 2008, preemptive wait types are properly listed and their associated task status is also marked as running. Now, SQL Server is in Non-Preemptive mode by default and it works fine. When CLR, extended Stored Procedures and other external components run, they run in Preemptive mode, leading to the creation of these wait types. There are a wide variety of preemptive wait types. If you see consistent high value in the Preemptive wait types, I strongly suggest that you look into the wait type and try to know the root cause. If you are still not sure, you can send me an email or leave a comment about it and I will do my best to help you reduce this wait type. Read all the post in the Wait Types and Queue series.

  • SQL SERVER – DMV – sys.dm_os_waiting_tasks and sys.dm_exec_requests – Wait Type – Day 4 of 28

    - by pinaldave
    Previously, we covered the DMV sys.dm_os_wait_stats, and also saw how it can be useful to identify the major resource bottleneck. However, at the same time, we discussed that this is only useful when we are looking at an instance-level picture. Quite often we want to know about the processes going in our server at the given instant. Here is the query for the same. This DMV is written taking the following into consideration: we want to analyze the queries that are currently running or which have recently ran and their plan is still in the cache. SELECT dm_ws.wait_duration_ms, dm_ws.wait_type, dm_es.status, dm_t.TEXT, dm_qp.query_plan, dm_ws.session_ID, dm_es.cpu_time, dm_es.memory_usage, dm_es.logical_reads, dm_es.total_elapsed_time, dm_es.program_name, DB_NAME(dm_r.database_id) DatabaseName, -- Optional columns dm_ws.blocking_session_id, dm_r.wait_resource, dm_es.login_name, dm_r.command, dm_r.last_wait_type FROM sys.dm_os_waiting_tasks dm_ws INNER JOIN sys.dm_exec_requests dm_r ON dm_ws.session_id = dm_r.session_id INNER JOIN sys.dm_exec_sessions dm_es ON dm_es.session_id = dm_r.session_id CROSS APPLY sys.dm_exec_sql_text (dm_r.sql_handle) dm_t CROSS APPLY sys.dm_exec_query_plan (dm_r.plan_handle) dm_qp WHERE dm_es.is_user_process = 1 GO You can change CROSS APPLY to OUTER APPLY if you want to see all the details which are omitted because of the plan cache. Let us analyze the result of the above query and see how it can be helpful to identify the query and the kind of wait type it creates. Click to Enlarage The above query will return various columns. There are various columns that provide very important details. e.g. wait_duration_ms – it indicates current wait for the query that executes at that point of time. wait_type – it indicates the current wait type for the query text – indicates the query text query_plan – when clicked on the same, it will display the query plans There are many other important information like CPU_time, memory_usage, and logical_reads, which can be read from the query as well. In future posts on this series, we will see how once identified wait type we can attempt to reduce the same. Read all the post in the Wait Types and Queue series.

  • Need to sanity-check my .htaccess, especially Limit GET POST line for Google repellent

    - by jose
    I need a sanity check on this .htaccess (from a WordPress site) I inherited from a 5 month+ old site. What's the symptom? Google + Bing crawl, but don't index any of the pages. Let me be clear: I'm not mad about "not ranking high." I think something is (accidentally) rejecting search engine indexing. I am not an expert on .htaccess, but one part especially looked funny, the Limit GET POST line. Is it not weird to have both Allow and Deny all, with no parameters? Also, I've ruled out robots.txt, but if I were you I'd want to see it, so here it is: User-agent: * Crawl-delay: 30 And here's the more suspect .htaccess: # temp redirect wordpress content feeds to feedburner <IfModule mod_rewrite.c> RewriteEngine on RewriteCond %{HTTP_USER_AGENT} !FeedBurner [NC] RewriteCond %{HTTP_USER_AGENT} !FeedValidator [NC] RewriteRule ^feed/?([_0-9a-z-]+)?/?$ http://feeds.feedburner.com/anonymousblog [R=302,NC,L] </IfModule> # temp redirect wordpress comment feeds to feedburner <IfModule mod_rewrite.c> RewriteEngine on RewriteCond %{HTTP_USER_AGENT} !FeedBurner [NC] RewriteCond %{HTTP_USER_AGENT} !FeedValidator [NC] RewriteRule ^comments/feed/?([_0-9a-z-]+)?/?$ http://feeds.feedburner.com/anonymous_comments [R=302,NC,L] </IfModule> <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> IndexIgnore .htaccess */.??* *~ *# */HEADER* */README* */_vti* <Limit GET POST> order deny,allow deny from all allow from all </Limit> <Limit PUT DELETE> order deny,allow deny from all </Limit> php_value memory_limit 32M Adding header by request: <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <meta name="robots" content="noindex,nofollow" /> <meta name="description" content="buncha junk i've deleted." /> <meta name="keywords" content="keywords i've deleted" /> <meta name="viewport" content="width=device-width" />

  • SQL SERVER – Puzzle Involving NULL – Resolve – Error – Operand data type void type is invalid for sum operator

    - by pinaldave
    Today is Monday let us start this week with interesting puzzle. Yesterday I had also posted quick question here: SQL SERVER – T-SQL Scripts to Find Maximum between Two Numbers Run following code: SELECT SUM(data) FROM (SELECT NULL AS DATA) t It will throw following error. Msg 8117, Level 16, State 1, Line 1 Operand data type void type is invalid for sum operator. I can easily fix if I use ISNULL Function as displayed following. SELECT SUM(data) FROM (SELECT ISNULL(NULL,0) AS DATA) t Above script will not throw an error. However, there is one more method how this can be fixed. Can you come up with another method which will not generate error?

  • Entity Type specific updates in entity component system

    - by Nathan
    I am currently familiarizing myself with the entity component paradigm. For an example, take a collision system, that detects if entities collide and if they do let them explode. So the collision system has to test collision based on the position component and then set the state of those entities to exploding. But what if the "effect" (setting the state to exploding) is different for different entities? For example, a ship fades out while for an asteroid a particle system must be created. Since entities and components are only data, this must happen in some system. The collision system could do it, but then it must switch over the entity type, which in my opinion is a cumbersome and difficult to extend solution. So how do I trigger "entity type dependend" updates on an entity?

  • Why prefer a wildcard to a type discriminator in a Java API (Re: Effective Java)

    - by Michael Campbell
    In the generics section of Bloch's Effective Java (which handily is the "free" chapter available to all: http://java.sun.com/docs/books/effective/generics.pdf), he says: If a type parameter appears only once in a method declaration, replace it with a wildcard. (See page 31-33 of that pdf) The signature in question is: public static void swap(List<?> list, int i, int j) vs public static void swap(List<E> list, int i, int j) And then proceeds to use a static private "helper" function with an actual type parameter to perform the work. The helper function signature is EXACTLY that of the second option. Why is the wildcard preferable, since you need to NOT use a wildcard to get the work done anyway? I understand that in this case since he's modifying the List and you can't add to a collection with an unbounded wildcard, so why use it at all?

  • Abstract Data Type and Data Structure

    - by mark075
    It's quite difficult for me to understand these terms. I searched on google and read a little on Wikipedia but I'm still not sure. I've determined so far that: Abstract Data Type is a definition of new type, describes its properties and operations. Data Structure is an implementation of ADT. Many ADT can be implemented as the same Data Structure. If I think right, array as ADT means a collection of elements and as Data Structure, how it's stored in a memory. Stack is ADT with push, pop operations, but can we say about stack data structure if I mean I used stack implemented as an array in my algorithm? And why heap isn't ADT? It can be implemented as tree or an array.

  • Building Custom HTTP Help Pages with WCF

    Been asked this a few times and needed to figure it out myself, so I put together a post on how to host custom HTTP help pages for your WCF services: http://blog.iserviceoriented.com/index.php/2010/05/04/building-custom-http-help-pages-with-wcf/ A little help from the WCF team to open up some of the internal classes would make it more straightforward... until them, it takes a bit of hacking and black magic.
