• Why doesn't sed's automatic printing deliver the expected results?

  - by CodeGnome

  What Works This sed script works as intended: $ echo -e "2\n1\n4\n3" | sed -n 'h; n; G; p' 1 2 3 4 It takes pair of input lines at a time, and swaps the lines. So far, so good. What Doesn't Work What I don't understand is why I can't use sed's automatic printing. Since sed automatically prints the pattern space at the end of each execution cycle (except when it's suppressed), why is this not equivalent? $ echo -e "2\n1\n4\n3" | sed 'h; n; G' 2 1 2 4 3 4 What I think the code says is: The input line is copied to the hold space. The next line is read into the pattern space. The hold space is appended to the pattern space. The pattern space (line1 + newline + line2) is printed automatically because we've reached the end of the execution cycle. Obviously, I'm wrong...but I don't understand why. Can anyone explain why this second example breaks, and why print suppression is needed to yield the correct results?

• PHP - Patterns within Arrays

  - by Toby

  I am trying to create a function which maps a recurring pattern of integers using an array. As an example if I have a starting array of (0,1,3) and I know that I want to stop the pattern when I hit 15. The pattern gets incremented by a fixed integer each time (lets say 4) so my final pattern should be.. 0 1 3 4 (0 + 4) 5 (1 + 4) 7 (2 + 4) 8 (4 + 4) 9 (5 + 4) 11(7 + 4) 12(8 + 4) 13(9 + 4) 15(11+ 4) Does anyone have any pointers on how this can be achieved? My current implementation works but is stupidly inefficient which something like this... $array = array(0,1,3); $inc = 4; $end = end($array); $final = 15; while($end < $final) { $tmp = array(); foreach($array AS $row) { $tmp = $row + $inc; } $array = merge($tmp, $array); $end = end($array); }

• Integrate SharePoint 2010 with Team Foundation Server 2010

  - by Martin Hinshelwood

  Our client is using a brand new shiny installation of SharePoint 2010, so we need to integrate our upgraded Team Foundation Server 2010 instance into it. In order to do that you need to run the Team Foundation Server 2010 install on the SharePoint 2010 server and choose to install only the “Extensions for SharePoint Products and Technologies”. We want out upgraded Team Project Collection to create any new portal in this SharePoint 2010 server farm. There a number of goodies above and beyond a solution file that requires the install, with the main one being the TFS2010 client API. These goodies allow proper integration with the creation and viewing of Work Items from SharePoint a new feature with TFS 2010. This works in both SharePoint 2007 and SharePoint 2010 with the level of integration dependant on the version of SharePoint that you are running. There are three levels of integration with “SharePoint Services 3.0” or “SharePoint Foundation 2010” being the lowest. This level only offers reporting services framed integration for reporting along with Work Item Integration and document management. The highest is Microsoft Office SharePoint Services (MOSS) Enterprise with Excel Services integration providing some lovely dashboards. Figure: Dashboards take the guessing out of Project Planning and estimation. Plus writing these reports would be boring!   The Extensions that you need are on the same installation media as the main TFS install and the only difference is the options you pick during the install. Figure: Installing the TFS 2010 Extensions for SharePoint Products and Technologies onto SharePoint 2010   Annoyingly you may need to reboot a couple of times, but on this server the process was MUCH smother than on our internal server. I think this was mostly to do with this being a clean install. Once it is installed you need to run the configuration. This will add all of the Solution and Templates that are needed for SharePoint to work properly with TFS. Figure: This is where all the TFS 2010 goodies are added to your SharePoint 2010 server and the TFS 2010 object model is installed.   Figure: All done, you have everything installed, but you still need to configure it Now that we have the TFS 2010 SharePoint Extensions installed on our SharePoint 2010 server we need to configure them both so that they will talk happily to each other. Configuring the SharePoint 2010 Managed path for Team Foundation Server 2010 In order for TFS to automatically create your project portals you need a wildcard managed path setup. This is where TFS will create the portal during the creation of a new Team project. To find the managed paths page for any application you need to first select the “Managed web applications”  link from the SharePoint 2010 Central Administration screen. Figure: Find the “Manage web applications” link under the “Application Management” section. On you are there you will see that the “Managed Paths” are there, they are just greyed out and selecting one of the applications will enable it to be clicked. Figure: You need to select an application for the SharePoint 2010 ribbon to activate.   Figure: You need to select an application before you can get to the Managed Paths for that application. Now we need to add a managed path for TFS 2010 to create its portals under. I have gone for the obvious option of just calling the managed path “TFS02” as the TFS 2010 server is the second TFS server that the client has installed, TFS 2008 being the first. This links the location to the server name, and as you can’t have two projects of the same name in two separate project collections there is unlikely to be any conflicts. Figure: Add a “tfs02” wildcard inclusion path to your SharePoint site. Configure the Team Foundation Server 2010 connection to SharePoint 2010 In order to have you new TFS 2010 Server talk to and create sites in SharePoint 2010 you need to tell the TFS server where to put them. As this TFS 2010 server was installed in out-of-the-box mode it has a SharePoint Services 3.0 (the free one) server running on the same box. But we want to change that so we can use the external SharePoint 2010 instance. Just open the “Team Foundation Server Administration Console” and navigate to the “SharePoint Web Applications” section. Here you click “Add” and enter the details for the Managed path we just created. Figure: If you have special permissions on your SharePoint you may need to add accounts to the “Service Accounts” section.    Before we can se this new SharePoint 2010 instance to be the default for our upgraded Team Project Collection we need to configure SharePoint to take instructions from our TFS server. Configure SharePoint 2010 to connect to Team Foundation Server 2010 On your SharePoint 2010 server open the Team Foundation Server Administration Console and select the “Extensions for SharePoint Products and Technologies” node. Here we need to “grant access” for our TFS 2010 server to create sites. Click the “Grant access” link and  fill out the full URL to the  TFS server, for example http://servername.domain.com:8080/tfs, and if need be restrict the path that TFS sites can be created on. Remember that when the users create a new team project they can change the default and point it anywhere they like as long as it is an authorised SharePoint location. Figure: Grant access for your TFS 2010 server to create sites in SharePoint 2010 Now that we have an authorised location for our team project portals to be created we need to tell our Team Project Collection that this is where it should stick sites by default for any new Team Projects created. Configure the Team Foundation Server 2010 Team Project Collection to create new sites in SharePoint 2010 Back on out TFS 2010 server we need to setup the defaults for our upgraded Team Project Collection to the new SharePoint 2010 integration we have just set up. On the TFS 2010 server open up the “Team Foundation Server Administration Console” again and navigate to the “Team Project Collections” node. Once you are there you will see a list of all of your TPC’s and in our case we have a DefaultCollection as well as out named and Upgraded collection for TFS 2008. If you select the “SharePoint Site” tab we can see that it is not currently configured. Figure: Our new Upgrade TFS2008 Team Project Collection does not have SharePoint configured Select to “Edit Default Site Location” and select the new integration point that we just set up for SharePoint 2010. Once you have selected the “SharePoint Web Application” (the thing we just configured) then it will give you an example based on that configuration point and the name of the Team Project Collection that we are configuring. Figure: Set the default location for new Team Project Portals to be created for this Team Project Collection This is where the reason for configuring the Extensions on the SharePoint 2010 server before doing this last bit becomes apparent. TFS 2010 is going to create a site at our http://sharepointserver/tfs02/ location called http://sharepointserver/tfs02/[TeamProjectCollection], or whatever we had specified, and it would have had difficulty doing this if we had not given it permission first. Figure: If there is no Team Project Collection site at this location the TFS 2010 server is going to create one This will create a nice Team Project Collection parent site to contain the Portals for any new Team Projects that are created. It is with noting that it will not create portals for existing Team Projects as this process is run during the Team Project Creation wizard. Figure: Just a basic parent site to host all of your new Team Project Portals as sub sites   You will need to add all of the users that will be creating Team Projects to be Administrators of this site so that they will not get an error during the Project Creation Wizard. You may also want to customise this as a proper portal to your projects if you are going to be having lots of them, but it is really just a default placeholder so you have a top level site that you can backup and point at. You have now integrated SharePoint 2010 and team Foundation Server 2010! You can now go forth and multiple your Team Projects for this Team Project Collection or you can continue to add portals to your other Collections.   Technorati Tags: TFS 2010,Sharepoint 2010,VS ALM

• WatiN screenshot saver

  - by Brian Schroer

  In addition to my automated unit, system and integration tests for ASP.NET projects, I like to give my customers something pretty that they can look at and visually see that the web site is behaving properly. I use the Gallio test runner to produce a pretty HTML report, and WatiN (Web Application Testing In .NET) to test the UI and create screenshots. I have a couple of issues with WatiN’s “CaptureWebPageToFile” method, though: It blew up the first (and only) time I tried it, possibly because… It scrolls down to capture the entire web page (I tried it on a very long page), and I usually don’t need that Also, sometimes I don’t need a picture of the whole browser window - I just want a picture of the element that I'm testing (for example, proving that a button has the correct caption). I wrote a WatiN screenshot saver helper class with these methods: SaveBrowserWindowScreenshot(Watin.Core.IE ie)  / SaveBrowserWindowScreenshot(Watin.Core.Element element) saves a screenshot of the browser window SaveBrowserWindowScreenshotWithHighlight(Watin.Core.Element element) saves a screenshot of the browser window, with the specified element scrolled into view and highlighted SaveElementScreenshot(Watin.Core.Element element) saves a picture of only the specified element The element highlighting improves on the built-in WatiN method (which just gives the element a yellow background, and makes the element pretty much unreadable when you have a light foreground color) by adding the ability to specify a HighlightCssClassName that points to a style in your site’s stylesheet. This code is specifically for testing with Internet Explorer (‘cause that’s what I have to test with at work), but you’re welcome to take it and do with it what you want… using System; using System.Drawing; using System.Drawing.Imaging; using System.IO; using System.Reflection; using System.Runtime.InteropServices; using System.Text; using System.Threading; using SHDocVw; using WatiN.Core; using mshtml; namespace BrianSchroer.TestHelpers { public static class WatinScreenshotSaver { public static void SaveBrowserWindowScreenshotWithHighlight (Element element, string screenshotName) { HighlightElement(element, true); SaveBrowserWindowScreenshot(element, screenshotName); HighlightElement(element, false); } public static void SaveBrowserWindowScreenshotWithHighlight(Element element) { HighlightElement(element, true); SaveBrowserWindowScreenshot(element); HighlightElement(element, false); } public static void SaveBrowserWindowScreenshot(Element element, string screenshotName) { SaveScreenshot(GetIe(element), screenshotName, SaveBitmapForCallbackArgs); } public static void SaveBrowserWindowScreenshot(Element element) { SaveScreenshot(GetIe(element), null, SaveBitmapForCallbackArgs); } public static void SaveBrowserWindowScreenshot(IE ie, string screenshotName) { SaveScreenshot(ie, screenshotName, SaveBitmapForCallbackArgs); } public static void SaveBrowserWindowScreenshot(IE ie) { SaveScreenshot(ie, null, SaveBitmapForCallbackArgs); } public static void SaveElementScreenshot(Element element, string screenshotName) { // TODO: Figure out how to get browser window "chrome" size and not have to go to full screen: var iex = (InternetExplorerClass) GetIe(element).InternetExplorer; bool fullScreen = iex.FullScreen; if (!fullScreen) iex.FullScreen = true; ScrollIntoView(element); SaveScreenshot(GetIe(element), screenshotName, args => SaveElementBitmapForCallbackArgs(element, args)); iex.FullScreen = fullScreen; } public static void SaveElementScreenshot(Element element) { SaveElementScreenshot(element, null); } private static void SaveScreenshot(IE browser, string screenshotName, Action<ScreenshotCallbackArgs> screenshotCallback) { string fileName = string.Format("{0:000}{1}{2}.jpg", ++_screenshotCount, (string.IsNullOrEmpty(screenshotName)) ?

• Creating packages in code - Package Configurations

  Continuing my theme of building various types of packages in code, this example shows how to building a package with package configurations. Incidentally it shows you how to add a variable, and a connection too. It covers the five most common configurations: Configuration File Indirect Configuration File SQL Server Indirect SQL Server Environment Variable  For a general overview try the SQL Server Books Online Package Configurations topic. The sample uses a a simple helper function ApplyConfig to create or update a configuration, although in the example we will only ever create. The most useful knowledge is the configuration string (Configuration.ConfigurationString) that you need to set. Configuration Type Configuration String Description Configuration File The full path and file name of an XML configuration file. The file can contain one or more configuration and includes the target path and new value to set. Indirect Configuration File An environment variable the value of which contains full path and file name of an XML configuration file as per the Configuration File type described above. SQL Server A three part configuration string, with each part being quote delimited and separated by a semi-colon. -- The first part is the connection manager name. The connection tells you which server and database to look for the configuration table. -- The second part is the name of the configuration table. The table is of a standard format, use the Package Configuration Wizard to help create an example, or see the sample script files below. The table contains one or more rows or configuration items each with a target path and new value. -- The third and final part is the optional filter name. A configuration table can contain multiple configurations, and the filter is  literal value that can be used to group items together and act as a filter clause when configurations are being read. If you do not need a filter, just leave the value empty. Indirect SQL Server An environment variable the value of which is the three part configuration string as per the SQL Server type described above. Environment Variable An environment variable the value of which is the value to set in the package. This is slightly different to the other examples as the configuration definition in the package also includes the target information. In our ApplyConfig function this is the only example that actually supplies a target value for the Configuration.PackagePath property. The path is an XPath style path for the target property, \Package.Variables[User::Variable].Properties[Value], the equivalent of which can be seen in the screenshot below, with the object being our variable called Variable, and the property to set is the Value property of that variable object. The configurations as seen when opening the generated package in BIDS: The sample code creates the package, adds a variable and connection manager, enables configurations, and then adds our example configurations. The package is then saved to disk, useful for checking the package and testing, before finally executing, just to prove it is valid. There are some external resources used here, namely some environment variables and a table, see below for more details. namespace Konesans.Dts.Samples { using System; using Microsoft.SqlServer.Dts.Runtime; public class PackageConfigurations { public void CreatePackage() { // Create a new package Package package = new Package(); package.Name = "ConfigurationSample"; // Add a variable, the target for our configurations package.Variables.Add("Variable", false, "User", 0); // Add a connection, for SQL configurations // Add the SQL OLE-DB connection ConnectionManager connectionManagerOleDb = package.Connections.Add("OLEDB"); connectionManagerOleDb.Name = "SQLConnection"; connectionManagerOleDb.ConnectionString = "Provider=SQLOLEDB.1;Data Source=(local);Initial Catalog=master;Integrated Security=SSPI;"; // Add our example configurations, first must enable package setting package.EnableConfigurations = true; // Direct configuration file, see sample file this.ApplyConfig(package, "Configuration File", DTSConfigurationType.ConfigFile, "C:\\Temp\\XmlConfig.dtsConfig", string.Empty); // Indirect configuration file, the emvironment variable XmlConfigFileEnvironmentVariable // contains the path to the configuration file, e.g. C:\Temp\XmlConfig.dtsConfig this.ApplyConfig(package, "Indirect Configuration File", DTSConfigurationType.IConfigFile, "XmlConfigFileEnvironmentVariable", string.Empty); // Direct SQL Server configuration, uses the SQLConnection package connection to read // configurations from the [dbo].[SSIS Configurations] table, with a filter of "SampleFilter" this.ApplyConfig(package, "SQL Server", DTSConfigurationType.SqlServer, "\"SQLConnection\";\"[dbo].[SSIS Configurations]\";\"SampleFilter\";", string.Empty); // Indirect SQL Server configuration, the environment variable "SQLServerEnvironmentVariable" // contains the configuration string e.g. "SQLConnection";"[dbo].[SSIS Configurations]";"SampleFilter"; this.ApplyConfig(package, "Indirect SQL Server", DTSConfigurationType.ISqlServer, "SQLServerEnvironmentVariable", string.Empty); // Direct environment variable, the value of the EnvironmentVariable environment variable is // applied to the target property, the value of the "User::Variable" package variable this.ApplyConfig(package, "EnvironmentVariable", DTSConfigurationType.EnvVariable, "EnvironmentVariable", "\\Package.Variables[User::Variable].Properties[Value]"); #if DEBUG // Save package to disk, DEBUG only new Application().SaveToXml(String.Format(@"C:\Temp\{0}.dtsx", package.Name), package, null); Console.WriteLine(@"C:\Temp\{0}.dtsx", package.Name); #endif // Execute package package.Execute(); // Basic check for warnings foreach (DtsWarning warning in package.Warnings) { Console.WriteLine("WarningCode : {0}", warning.WarningCode); Console.WriteLine(" SubComponent : {0}", warning.SubComponent); Console.WriteLine(" Description : {0}", warning.Description); Console.WriteLine(); } // Basic check for errors foreach (DtsError error in package.Errors) { Console.WriteLine("ErrorCode : {0}", error.ErrorCode); Console.WriteLine(" SubComponent : {0}", error.SubComponent); Console.WriteLine(" Description : {0}", error.Description); Console.WriteLine(); } package.Dispose(); } /// <summary> /// Add or update an package configuration. /// </summary> /// <param name="package">The package.</param> /// <param name="name">The configuration name.</param> /// <param name="type">The type of configuration</param> /// <param name="setting">The configuration setting.</param> /// <param name="target">The target of the configuration, leave blank if not required.</param> internal void ApplyConfig(Package package, string name, DTSConfigurationType type, string setting, string target) { Configurations configurations = package.Configurations; Configuration configuration; if (configurations.Contains(name)) { configuration = configurations[name]; } else { configuration = configurations.Add(); } configuration.Name = name; configuration.ConfigurationType = type; configuration.ConfigurationString = setting; configuration.PackagePath = target; } } } The following table lists the environment variables required for the full example to work along with some sample values.

• Preserving Permalinks

  - by Daniel Moth

  One of the things that gets me on a rant is websites that break permalinks. If you have posted something somewhere and there is a public URL pointing to it, that URL should never ever return a 404. You are breaking all websites that ever linked to you and you are breaking all search engine links to your content (that others will try and follow). It is a pet peeve of mine. So when I had to move my blog, obviously I would preserve the root URL (www.danielmoth.com/Blog/), but I also wanted to preserve every URL my blog has generated over the years. To be clear, our focus here is on the URL formatting, not the content migration which I'll talk about in my next post. In this post, I'll describe my solution first and then what it solves. 1. The IIS7 Rewrite Module and web.config There are a few ways you can map an old URL to a new one (so when requests to the old URL come in, they get redirected to the new one). The new blog engine I use (dasBlog) has built-in functionality to do that (Scott refers to it here). Instead, the way I chose to address the issue was to use the IIS7 rewrite module. The IIS7 rewrite module allows redirecting URLs based on pattern matching, regular expressions and, of course, hardcoded full URLs for things that don't fall into any pattern. You can configure it visually from IIS Manager using a handy dialog that allows testing patterns against input URLs. Here is what mine looked like after configuring a few rules: To learn more about this technology check out this video, the reference page and this overview blog post; all 3 pages have a collection of related resources at the bottom worth checking out too. All the visual configuration ends up in a web.config file at the root folder of your website. If you are on a shared hosting service, probably the only way you can use the Rewrite Module is by directly editing the web.config file. Next, I'll describe the URLs I had to map and how that manifested itself in the web.config file. What I did was create the rules locally using the GUI, and then took the generated web.config file and uploaded it to my live site. You can view my web.config here. 2. Monthly Archives Observe the difference between the way the two blog engines generate this type of URL Blogger: /Blog/2004_07_01_mothblog_archive.html dasBlog: /Blog/default,month,2004-07.aspx In my web.config file, the rule that deals with this is the one named "monthlyarchive_redirect". 3. Categories Observe the difference between the way the two blog engines generate this type of URL Blogger: /Blog/labels/Personal.html dasBlog: /Blog/CategoryView,category,Personal.aspx In my web.config file the rule that deals with this is the one named "category_redirect". 4. Posts Observe the difference between the way the two blog engines generate this type of URL Blogger: /Blog/2004/07/hello-world.html dasBlog: /Blog/Hello-World.aspx In my web.config file the rule that deals with this is the one named "post_redirect". Note: The decision is taken to use dasBlog URLs that do not include the date info (see the description of my Appearance settings). If we included the date info then it would have to include the day part, which blogger did not generate. This makes it impossible to redirect correctly and to have a single permalink for blog posts moving forward. An implication of this decision, is that no two blog posts can have the same title. The tool I will describe in my next post (inelegantly) deals with duplicates, but not with triplicates or higher. 5. Unhandled by a generic rule Unfortunately, the two blog engines use different rules for generating URLs for blog posts. Most of the time the conversion is as simple as the example of the previous section where a post titled "Hello World" generates a URL with the words separated by a hyphen. Some times that is not the case, for example: /Blog/2006/05/medc-wrap-up.html /Blog/MEDC-Wrapup.aspx or /Blog/2005/01/best-of-moth-2004.html /Blog/Best-Of-The-Moth-2004.aspx or /Blog/2004/11/more-windows-mobile-2005-details.html /Blog/More-Windows-Mobile-2005-Details-Emerge.aspx In short, blogger does not add words to the title beyond ~39 characters, it drops some words from the title generation (e.g. a, an, on, the), and it preserve hyphens that appear in the title. For this reason, we need to detect these and explicitly list them for redirects (no regular expression can help here because the full set of rules is not listed anywhere). In my web.config file the rule that deals with this is the one named "Redirect rule1 for FullRedirects" combined with the rewriteMap named "StaticRedirects". Note: The tool I describe in my next post will detect all the URLs that need to be explicitly redirected and will list them in a file ready for you to copy them to your web.config rewriteMap. 6. C# code doing the same as the web.config I wrote some naive code that does the same thing as the web.config: given a string it will return a new string converted according to the 3 rules above. It does not take into account the 4th case where an explicit hard-coded conversion is needed (the tool I present in the next post does take that into account). static string REGEX_post_redirect = "[0-9]{4}/[0-9]{2}/([0-9a-z-]+).html"; static string REGEX_category_redirect = "labels/([_0-9a-z-% ]+).html"; static string REGEX_monthlyarchive_redirect = "([0-9]{4})_([0-9]{2})_[0-9]{2}_mothblog_archive.html"; static string Redirect(string oldUrl) { GroupCollection g; if (RunRegExOnIt(oldUrl, REGEX_post_redirect, 2, out g)) return string.Concat(g[1].Value, ".aspx"); if (RunRegExOnIt(oldUrl, REGEX_category_redirect, 2, out g)) return string.Concat("CategoryView,category,", g[1].Value, ".aspx"); if (RunRegExOnIt(oldUrl, REGEX_monthlyarchive_redirect, 3, out g)) return string.Concat("default,month,", g[1].Value, "-", g[2], ".aspx"); return string.Empty; } static bool RunRegExOnIt(string toRegEx, string pattern, int groupCount, out GroupCollection g) { if (pattern.Length == 0) { g = null; return false; } g = new Regex(pattern, RegexOptions.IgnoreCase | RegexOptions.Compiled).Match(toRegEx).Groups; return (g.Count == groupCount); } Comments about this post welcome at the original blog.

• Updating a SharePoint master page via a solution (WSP)

  In my last blog post, I wrote how to deploy a SharePoint theme using Features and a solution package.  As promised in that post, here is how to update an already deployed master page. There are several ways to update a master page in SharePoint.  You could upload a new version to the master page gallery, or you could upload a new master page to the gallery, and then set the site to use this new page.  Manually uploading your master page to the master page gallery might be the best option, depending on your environment.  For my client, I did these steps in code, which is what they preferred. (Image courtesy of: http://www.joiningdots.net/blog/2007/08/sharepoint-and-quick-launch.html ) Before you decide which method you need to use, take a look at your existing pages.  Are they using the SharePoint dynamic token or the static token for the master page reference?  The wha, huh? SO, there are four ways to tell an .aspx page hosted in SharePoint which master page it should use: “~masterurl/default.master” – tells the page to use the default.master property of the site “~masterurl/custom.master” – tells the page to use the custom.master property of the site “~site/default.master” – tells the page to use the file named “default.master” in the site’s master page gallery “~sitecollection/default.master” – tells the page to use the file named “default.master” in the site collection’s master page gallery For more information about these tokens, take a look at this article on MSDN. Once you determine which token your existing pages are pointed to, then you know which file you need to update.  So, if the ~masterurl tokens are used, then you upload a new master page, either replacing the existing one or adding another one to the gallery.  If you’ve uploaded a new file with a new name, you’ll just need to set it as the master page either through the UI (MOSS only) or through code (MOSS or WSS Feature receiver code – or using SharePoint Designer). If the ~site or ~sitecollection tokens were used, then you’re limited to either replacing the existing master page, or editing all of your existing pages to point to another master page.  In most cases, it probably makes sense to just replace the master page. For my project, I’m working with WSS and the existing pages are set to the ~sitecollection token.  Based on this, I decided to just upload a new version of the existing master page (and not modify the dozens of existing pages). Also, since my client prefers Features and solutions, I created a master page Feature and a corresponding Feature Receiver.  For information on creating the elements and feature files, check out this post: http://sharepointmagazine.net/technical/development/deploying-the-master-page . This works fine, unless you are overwriting an existing master page, which was my case.  You’ll run into errors because the master page file needs to be checked out, replaced, and then checked in.  I wrote code in my Feature Activated event handler to accomplish these steps. Here are the steps necessary in code: Get the file name from the elements file of the Feature Check out the file from the master page gallery Upload the file to the master page gallery Check in the file to the master page gallery Here’s the code in my Feature Receiver: 1: public override void FeatureActivated(SPFeatureReceiverProperties properties) 2: { 3: try 4: { 5:   6: SPElementDefinitionCollection col = properties.Definition.GetElementDefinitions(System.Globalization.CultureInfo.CurrentCulture); 7:   8: using (SPWeb curweb = GetCurWeb(properties)) 9: { 10: foreach (SPElementDefinition ele in col) 11: { 12: if (string.Compare(ele.ElementType, "Module", true) == 0) 13: { 14: // <Module Name="DefaultMasterPage" List="116" Url="_catalogs/masterpage" RootWebOnly="FALSE"> 15: // <File Url="myMaster.master" Type="GhostableInLibrary" IgnoreIfAlreadyExists="TRUE" 16: // Path="MasterPages/myMaster.master" /> 17: // </Module> 18: string Url = ele.XmlDefinition.Attributes["Url"].Value; 19: foreach (System.Xml.XmlNode file in ele.XmlDefinition.ChildNodes) 20: { 21: string Url2 = file.Attributes["Url"].Value; 22: string Path = file.Attributes["Path"].Value; 23: string fileType = file.Attributes["Type"].Value; 24:   25: if (string.Compare(fileType, "GhostableInLibrary", true) == 0) 26: { 27: //Check out file in document library 28: SPFile existingFile = curweb.GetFile(Url + "/" + Url2); 29:   30: if (existingFile != null) 31: { 32: if (existingFile.CheckOutStatus != SPFile.SPCheckOutStatus.None) 33: { 34: throw new Exception("The master page file is already checked out. Please make sure the master page file is checked in, before activating this feature."); 35: } 36: else 37: { 38: existingFile.CheckOut(); 39: existingFile.Update(); 40: } 41: } 42:   43: //Upload file to document library 44: string filePath = System.IO.Path.Combine(properties.Definition.RootDirectory, Path); 45: string fileName = System.IO.Path.GetFileName(filePath); 46: char slash = Convert.ToChar("/"); 47: string[] folders = existingFile.ParentFolder.Url.Split(slash); 48:   49: if (folders.Length > 2) 50: { 51: Logger.logMessage("More than two folders were detected in the library path for the master page. Only two are supported.", 52: Logger.LogEntryType.Information); //custom logging component 53: } 54:   55: SPFolder myLibrary = curweb.Folders[folders[0]].SubFolders[folders[1]]; 56:   57: FileStream fs = File.OpenRead(filePath); 58:   59: SPFile newFile = myLibrary.Files.Add(fileName, fs, true); 60:   61: myLibrary.Update(); 62: newFile.CheckIn("Updated by Feature", SPCheckinType.MajorCheckIn); 63: newFile.Update(); 64: } 65: } 66: } 67: } 68: } 69: } 70: catch (Exception ex) 71: { 72: string msg = "Error occurred during feature activation"; 73: Logger.logException(ex, msg, ""); 74: } 75:   76: } 77:   78: /// <summary> 79: /// Using a Feature's properties, get a reference to the Current Web 80: /// </summary> 81: /// <param name="properties"></param> 82: public SPWeb GetCurWeb(SPFeatureReceiverProperties properties) 83: { 84: SPWeb curweb; 85:   86: //Check if the parent of the web is a site or a web 87: if (properties != null && properties.Feature.Parent.GetType().ToString() == "Microsoft.SharePoint.SPWeb") 88: { 89:   90: //Get web from parent 91: curweb = (SPWeb)properties.Feature.Parent; 92: 93: } 94: else 95: { 96: //Get web from Site 97: using (SPSite cursite = (SPSite)properties.Feature.Parent) 98: { 99: curweb = (SPWeb)cursite.OpenWeb(); 100: } 101: } 102:   103: return curweb; 104: } This did the trick.  It allowed me to update my existing master page, through an easily repeatable process (which is great when you are working with more than one environment and what to do things like TEST it!).  I did run into what I would classify as a strange issue with one of my subsites, but that’s the topic for another blog post.

• No GLX on Intel card with multiseat with additional nVidia card

  - by MeanEYE

  I have multiseat configured and my Xorg has 2 server layouts. One is for nVidia card and other is for Intel card. They both work, but display server assigned to Intel card doesn't have hardware acceleration since DRI and GLX module being used is from nVidia driver. So my question is, can I configure layouts somehow to use right DRI and GLX with each card?

• We've completed the first iteration

  - by CliveT

  There are a lot of features in C# that are implemented by the compiler and not by the underlying platform. One such feature is a lambda expression. Since local variables cannot be accessed once the current method activation finishes, the compiler has to go out of its way to generate a new class which acts as a home for any variable whose lifetime needs to be extended past the activation of the procedure. Take the following example:     Random generator = new Random();     Func func = () = generator.Next(10); In this case, the compiler generates a new class called c_DisplayClass1 which is marked with the CompilerGenerated attribute. [CompilerGenerated] private sealed class c__DisplayClass1 {     // Fields     public Random generator;     // Methods     public int b__0()     {         return this.generator.Next(10);     } } Two quick comments on this: (i)    A display was the means that compilers for languages like Algol recorded the various lexical contours of the nested procedure activations on the stack. I imagine that this is what has led to the name. (ii)    It is a shame that the same attribute is used to mark all compiler generated classes as it makes it hard to figure out what they are being used for. Indeed, you could imagine optimisations that the runtime could perform if it knew that classes corresponded to certain high level concepts. We can see that the local variable generator has been turned into a field in the class, and the body of the lambda expression has been turned into a method of the new class. The code that builds the Func object simply constructs an instance of this class and initialises the fields to their initial values.     c__DisplayClass1 class2 = new c__DisplayClass1();     class2.generator = new Random();     Func func = new Func(class2.b__0); Reflector already contains code to spot this pattern of code and reproduce the form containing the lambda expression, so this is example is correctly decompiled. The use of compiler generated code is even more spectacular in the case of iterators. C# introduced the idea of a method that could automatically store its state between calls, so that it can pick up where it left off. The code can express the logical flow with yield return and yield break denoting places where the method should return a particular value and be prepared to resume.         {             yield return 1;             yield return 2;             yield return 3;         } Of course, there was already a .NET pattern for expressing the idea of returning a sequence of values with the computation proceeding lazily (in the sense that the work for the next value is executed on demand). This is expressed by the IEnumerable interface with its Current property for fetching the current value and the MoveNext method for forcing the computation of the next value. The sequence is terminated when this method returns false. The C# compiler links these two ideas together so that an IEnumerator returning method using the yield keyword causes the compiler to produce the implementation of an Iterator. Take the following piece of code.         IEnumerable GetItems()         {             yield return 1;             yield return 2;             yield return 3;         } The compiler implements this by defining a new class that implements a state machine. This has an integer state that records which yield point we should go to if we are resumed. It also has a field that records the Current value of the enumerator and a field for recording the thread. This latter value is used for optimising the creation of iterator instances. [CompilerGenerated] private sealed class d__0 : IEnumerable, IEnumerable, IEnumerator, IEnumerator, IDisposable {     // Fields     private int 1__state;     private int 2__current;     public Program 4__this;     private int l__initialThreadId; The body gets converted into the code to construct and initialize this new class. private IEnumerable GetItems() {     d__0 d__ = new d__0(-2);     d__.4__this = this;     return d__; } When the class is constructed we set the state, which was passed through as -2 and the current thread. public d__0(int 1__state) {     this.1__state = 1__state;     this.l__initialThreadId = Thread.CurrentThread.ManagedThreadId; } The state needs to be set to 0 to represent a valid enumerator and this is done in the GetEnumerator method which optimises for the usual case where the returned enumerator is only used once. IEnumerator IEnumerable.GetEnumerator() {     if ((Thread.CurrentThread.ManagedThreadId == this.l__initialThreadId)               && (this.1__state == -2))     {         this.1__state = 0;         return this;     } The state machine itself is implemented inside the MoveNext method. private bool MoveNext() {     switch (this.1__state)     {         case 0:             this.1__state = -1;             this.2__current = 1;             this.1__state = 1;             return true;         case 1:             this.1__state = -1;             this.2__current = 2;             this.1__state = 2;             return true;         case 2:             this.1__state = -1;             this.2__current = 3;             this.1__state = 3;             return true;         case 3:             this.1__state = -1;             break;     }     return false; } At each stage, the current value of the state is used to determine how far we got, and then we generate the next value which we return after recording the next state. Finally we return false from the MoveNext to signify the end of the sequence. Of course, that example was really simple. The original method body didn't have any local variables. Any local variables need to live between the calls to MoveNext and so they need to be transformed into fields in much the same way that we did in the case of the lambda expression. More complicated MoveNext methods are required to deal with resources that need to be disposed when the iterator finishes, and sometimes the compiler uses a temporary variable to hold the return value. Why all of this explanation? We've implemented the de-compilation of iterators in the current EAP version of Reflector (7). This contrasts with previous version where all you could do was look at the MoveNext method and try to figure out the control flow. There's a fair amount of things we have to do. We have to spot the use of a CompilerGenerated class which implements the Enumerator pattern. We need to go to the class and figure out the fields corresponding to the local variables. We then need to go to the MoveNext method and try to break it into the various possible states and spot the state transitions. We can then take these pieces and put them back together into an object model that uses yield return to show the transition points. After that Reflector can carry on optimising using its usual optimisations. The pattern matching is currently a little too sensitive to changes in the code generation, and we only do a limited analysis of the MoveNext method to determine use of the compiler generated fields. In some ways, it is a pity that iterators are compiled away and there is no metadata that reflects the original intent. Without it, we are always going to dependent on our knowledge of the compiler's implementation. For example, we have noticed that the Async CTP changes the way that iterators are code generated, so we'll have to do some more work to support that. However, with that warning in place, we seem to do a reasonable job of decompiling the iterators that are built into the framework. Hopefully, the EAP will give us a chance to find examples where we don't spot the pattern correctly or regenerate the wrong code, and we can improve things. Please give it a go, and report any problems.

• java.lang.IllegalAccessException during Ant jwsc webservice build

  - by KevB

  Hi. I have a large application, part of which relies on a set of 3 webservices. I'm currently in the process of writing an Ant build script to build and package the application into an EAR file. When building the web sub-project for this application I use the <jwsc> task in Ant to compile the webservices. This causes an IllegalAccessException, as outlined in the stack trace below: [jwsc] warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds [jwsc] JWS: processing module weboutput [jwsc] Parsing source files [jwsc] Parsing source files [jwsc] 3 JWS files being processed for module weboutput [jwsc] JWS: C:\dev\ir\irWeb\src\webservices\DailyRun.java Validated.

I also found a single report on the Oracle forums that seemed to be a carbon copy of this issue, but there were no replies. The application is written in Weblogic Workshop 10, runs on Weblogic Server 10.3, and uses Beehive / NetUI. Not sure if that would make a difference or not though. The build scripts were automatically generated by Weblogic Workshop, with some tweaks and fixes made to other aspects of the files by myself to fix other compatability issues. I am using Java 1.6.0_23 from Sun, and Ant 1.8.1 Any help or advice would be greatly appreciated.

• Project compilation requires a class that is not used anywhere

  - by Susei

  When I build with ant my project that uses libgdx, I get a strange error. It says that a class com.google.gwt.dom.client.ImageElement is not found, but it isn't used at all in the code. How can I find what makes this class necessary? Even searching over the whole project doesn't give any results. It says that error is at PixmapTextureAtlas.java:16 (class source), but there is no code that uses that ImageElement class. Adding the library containing com.google.gwt.dom.client.ImageElement class helps, of course, but I'd like to figure out why this class in needed. Here is the place in ant log that tells of the actual error: Compiling 3 source files to /home/suseika/Projects/tendiwa/client/bin /home/suseika/Projects/tendiwa/client/src/org/tendiwa/client/PixmapTextureAtlas.java:16: error: cannot access ImageElement class file for com.google.gwt.dom.client.ImageElement not found Here is the whole ant log: /usr/lib/jvm/java-7-oracle/bin/java -Xmx128m -Xss2m -Dant.home=/opt/intellijidea/lib/ant -Dant.library.dir=/opt/intellijidea/lib/ant/lib -Dfile.encoding=UTF-8 -classpath /opt/intellijidea/lib/ant/lib/ant-apache-regexp.jar:/opt/intellijidea/lib/ant/lib/ant-swing.jar:/opt/intellijidea/lib/ant/lib/ant-apache-xalan2.jar:/opt/intellijidea/lib/ant/lib/ant-jdepend.jar:/opt/intellijidea/lib/ant/lib/ant-apache-resolver.jar:/opt/intellijidea/lib/ant/lib/ant-jsch.jar:/opt/intellijidea/lib/ant/lib/ant.jar:/opt/intellijidea/lib/ant/lib/ant-testutil.jar:/opt/intellijidea/lib/ant/lib/ant-launcher.jar:/opt/intellijidea/lib/ant/lib/ant-apache-bsf.jar:/opt/intellijidea/lib/ant/lib/ant-commons-logging.jar:/opt/intellijidea/lib/ant/lib/ant-netrexx.jar:/opt/intellijidea/lib/ant/lib/ant-junit.jar:/opt/intellijidea/lib/ant/lib/ant-commons-net.jar:/opt/intellijidea/lib/ant/lib/ant-apache-bcel.jar:/opt/intellijidea/lib/ant/lib/ant-antlr.jar:/opt/intellijidea/lib/ant/lib/ant-apache-log4j.jar:/opt/intellijidea/lib/ant/lib/ant-jai.jar:/opt/intellijidea/lib/ant/lib/ant-apache-oro.jar:/opt/intellijidea/lib/ant/lib/ant-jmf.jar:/opt/intellijidea/lib/ant/lib/ant-javamail.jar:/usr/lib/jvm/java-7-oracle/lib/tools.jar:/opt/intellijidea/lib/idea_rt.jar com.intellij.rt.ant.execution.AntMain2 -logger com.intellij.rt.ant.execution.IdeaAntLogger2 -inputhandler com.intellij.rt.ant.execution.IdeaInputHandler -buildfile /home/suseika/Projects/tendiwa/client/build.xml jar build.xml property path description compile ant property property property description compile mkdir javac jar ant property description _core_src_available available ontology antcall property description _core_src_available available _build_core ant property property compile echo /home/suseika/Projects/tendiwa/client mkdir javac jar jar Building jar: /home/suseika/Projects/tendiwa/MainModule.jar description tempfile mkdir Created dir: /tmp/tendiwa373148820 unjar Expanding: /home/suseika/Projects/tendiwa/MainModule.jar into /tmp/tendiwa373148820 Expanding: /home/suseika/Projects/tendiwa/tendiwa-backend.jar into /tmp/tendiwa373148820 Expanding: /home/suseika/Projects/tendiwa/tendiwa-ontology.jar into /tmp/tendiwa373148820 copy Copying 1 file to /tmp/tendiwa373148820 java Created item short_sword Created item short_bow Created item bucket Created item boot Created item steel_morningstar Created item rifle_ammo Created item handAxe Created item iron_armor Created item steel_mace Created item jacket Created item fedora Created item wooden_arrow Saving sources to /tmp/tendiwa373148820/ontology/src tendiwa/resources/SoundTypes.java tendiwa/resources/CharacterTypes.java tendiwa/resources/ObjectTypes.java tendiwa/resources/FloorTypes.java tendiwa/resources/ItemTypes.java tendiwa/resources/MaterialTypes.java mkdir mkdir mkdir Created dir: /tmp/tendiwa373148820/ontology/bin javac jar Building jar: /home/suseika/Projects/tendiwa/tendiwa-ontology.jar echo Resources source code generated ant property property compile echo /home/suseika/Projects/tendiwa/client mkdir javac jar jar jar Building jar: /home/suseika/Projects/tendiwa/MainModule.jar mkdir javac /home/suseika/Projects/tendiwa/client/build.xml:25: Compile failed;

• Windows Azure Service Bus Splitter and Aggregator

  - by Alan Smith

  This article will cover basic implementations of the Splitter and Aggregator patterns using the Windows Azure Service Bus. The content will be included in the next release of the “Windows Azure Service Bus Developer Guide”, along with some other patterns I am working on. I’ve taken the pattern descriptions from the book “Enterprise Integration Patterns” by Gregor Hohpe. I bought a copy of the book in 2004, and recently dusted it off when I started to look at implementing the patterns on the Windows Azure Service Bus. Gregor has also presented an session in 2011 “Enterprise Integration Patterns: Past, Present and Future” which is well worth a look. I’ll be covering more patterns in the coming weeks, I’m currently working on Wire-Tap and Scatter-Gather. There will no doubt be a section on implementing these patterns in my “SOA, Connectivity and Integration using the Windows Azure Service Bus” course. There are a number of scenarios where a message needs to be divided into a number of sub messages, and also where a number of sub messages need to be combined to form one message. The splitter and aggregator patterns provide a definition of how this can be achieved. This section will focus on the implementation of basic splitter and aggregator patens using the Windows Azure Service Bus direct programming model. In BizTalk Server receive pipelines are typically used to implement the splitter patterns, with sequential convoy orchestrations often used to aggregate messages. In the current release of the Service Bus, there is no functionality in the direct programming model that implements these patterns, so it is up to the developer to implement them in the applications that send and receive messages. Splitter A message splitter takes a message and spits the message into a number of sub messages. As there are different scenarios for how a message can be split into sub messages, message splitters are implemented using different algorithms. The Enterprise Integration Patterns book describes the splatter pattern as follows: How can we process a message if it contains multiple elements, each of which may have to be processed in a different way? Use a Splitter to break out the composite message into a series of individual messages, each containing data related to one item. The Enterprise Integration Patterns website provides a description of the Splitter pattern here. In some scenarios a batch message could be split into the sub messages that are contained in the batch. The splitting of a message could be based on the message type of sub-message, or the trading partner that the sub message is to be sent to. Aggregator An aggregator takes a stream or related messages and combines them together to form one message. The Enterprise Integration Patterns book describes the aggregator pattern as follows: How do we combine the results of individual, but related messages so that they can be processed as a whole? Use a stateful filter, an Aggregator, to collect and store individual messages until a complete set of related messages has been received. Then, the Aggregator publishes a single message distilled from the individual messages. The Enterprise Integration Patterns website provides a description of the Aggregator pattern here. A common example of the need for an aggregator is in scenarios where a stream of messages needs to be combined into a daily batch to be sent to a legacy line-of-business application. The BizTalk Server EDI functionality provides support for batching messages in this way using a sequential convoy orchestration. Scenario The scenario for this implementation of the splitter and aggregator patterns is the sending and receiving of large messages using a Service Bus queue. In the current release, the Windows Azure Service Bus currently supports a maximum message size of 256 KB, with a maximum header size of 64 KB. This leaves a safe maximum body size of 192 KB. The BrokeredMessage class will support messages larger than 256 KB; in fact the Size property is of type long, implying that very large messages may be supported at some point in the future. The 256 KB size restriction is set in the service bus components that are deployed in the Windows Azure data centers. One of the ways of working around this size restriction is to split large messages into a sequence of smaller sub messages in the sending application, send them via a queue, and then reassemble them in the receiving application. This scenario will be used to demonstrate the pattern implementations. Implementation The splitter and aggregator will be used to provide functionality to send and receive large messages over the Windows Azure Service Bus. In order to make the implementations generic and reusable they will be implemented as a class library. The splitter will be implemented in the LargeMessageSender class and the aggregator in the LargeMessageReceiver class. A class diagram showing the two classes is shown below. Implementing the Splitter The splitter will take a large brokered message, and split the messages into a sequence of smaller sub-messages that can be transmitted over the service bus messaging entities. The LargeMessageSender class provides a Send method that takes a large brokered message as a parameter. The implementation of the class is shown below; console output has been added to provide details of the splitting operation. public class LargeMessageSender {     private static int SubMessageBodySize = 192 * 1024;     private QueueClient m_QueueClient;       public LargeMessageSender(QueueClient queueClient)     {         m_QueueClient = queueClient;     }       public void Send(BrokeredMessage message)     {         // Calculate the number of sub messages required.         long messageBodySize = message.Size;         int nrSubMessages = (int)(messageBodySize / SubMessageBodySize);         if (messageBodySize % SubMessageBodySize != 0)         {             nrSubMessages++;         }           // Create a unique session Id.         string sessionId = Guid.NewGuid().ToString();         Console.WriteLine("Message session Id: " + sessionId);         Console.Write("Sending {0} sub-messages", nrSubMessages);           Stream bodyStream = message.GetBody<Stream>();         for (int streamOffest = 0; streamOffest < messageBodySize;             streamOffest += SubMessageBodySize)         {                                     // Get the stream chunk from the large message             long arraySize = (messageBodySize - streamOffest) > SubMessageBodySize                 ? SubMessageBodySize : messageBodySize - streamOffest;             byte[] subMessageBytes = new byte[arraySize];             int result = bodyStream.Read(subMessageBytes, 0, (int)arraySize);             MemoryStream subMessageStream = new MemoryStream(subMessageBytes);               // Create a new message             BrokeredMessage subMessage = new BrokeredMessage(subMessageStream, true);             subMessage.SessionId = sessionId;               // Send the message             m_QueueClient.Send(subMessage);             Console.Write(".");         }         Console.WriteLine("Done!");     }} The LargeMessageSender class is initialized with a QueueClient that is created by the sending application. When the large message is sent, the number of sub messages is calculated based on the size of the body of the large message. A unique session Id is created to allow the sub messages to be sent as a message session, this session Id will be used for correlation in the aggregator. A for loop in then used to create the sequence of sub messages by creating chunks of data from the stream of the large message. The sub messages are then sent to the queue using the QueueClient. As sessions are used to correlate the messages, the queue used for message exchange must be created with the RequiresSession property set to true. Implementing the Aggregator The aggregator will receive the sub messages in the message session that was created by the splitter, and combine them to form a single, large message. The aggregator is implemented in the LargeMessageReceiver class, with a Receive method that returns a BrokeredMessage. The implementation of the class is shown below; console output has been added to provide details of the splitting operation.   public class LargeMessageReceiver {     private QueueClient m_QueueClient;       public LargeMessageReceiver(QueueClient queueClient)     {         m_QueueClient = queueClient;     }       public BrokeredMessage Receive()     {         // Create a memory stream to store the large message body.         MemoryStream largeMessageStream = new MemoryStream();           // Accept a message session from the queue.         MessageSession session = m_QueueClient.AcceptMessageSession();         Console.WriteLine("Message session Id: " + session.SessionId);         Console.Write("Receiving sub messages");           while (true)         {             // Receive a sub message             BrokeredMessage subMessage = session.Receive(TimeSpan.FromSeconds(5));               if (subMessage != null)             {                 // Copy the sub message body to the large message stream.                 Stream subMessageStream = subMessage.GetBody<Stream>();                 subMessageStream.CopyTo(largeMessageStream);                   // Mark the message as complete.                 subMessage.Complete();                 Console.Write(".");             }             else             {                 // The last message in the sequence is our completeness criteria.                 Console.WriteLine("Done!");                 break;             }         }                     // Create an aggregated message from the large message stream.         BrokeredMessage largeMessage = new BrokeredMessage(largeMessageStream, true);         return largeMessage;     } }   The LargeMessageReceiver initialized using a QueueClient that is created by the receiving application. The receive method creates a memory stream that will be used to aggregate the large message body. The AcceptMessageSession method on the QueueClient is then called, which will wait for the first message in a message session to become available on the queue. As the AcceptMessageSession can throw a timeout exception if no message is available on the queue after 60 seconds, a real-world implementation should handle this accordingly. Once the message session as accepted, the sub messages in the session are received, and their message body streams copied to the memory stream. Once all the messages have been received, the memory stream is used to create a large message, that is then returned to the receiving application. Testing the Implementation The splitter and aggregator are tested by creating a message sender and message receiver application. The payload for the large message will be one of the webcast video files from http://www.cloudcasts.net/, the file size is 9,697 KB, well over the 256 KB threshold imposed by the Service Bus. As the splitter and aggregator are implemented in a separate class library, the code used in the sender and receiver console is fairly basic. The implementation of the main method of the sending application is shown below.   static void Main(string[] args) {     // Create a token provider with the relevant credentials.     TokenProvider credentials =         TokenProvider.CreateSharedSecretTokenProvider         (AccountDetails.Name, AccountDetails.Key);       // Create a URI for the serivce bus.     Uri serviceBusUri = ServiceBusEnvironment.CreateServiceUri         ("sb", AccountDetails.Namespace, string.Empty);       // Create the MessagingFactory     MessagingFactory factory = MessagingFactory.Create(serviceBusUri, credentials);       // Use the MessagingFactory to create a queue client     QueueClient queueClient = factory.CreateQueueClient(AccountDetails.QueueName);       // Open the input file.     FileStream fileStream = new FileStream(AccountDetails.TestFile, FileMode.Open);       // Create a BrokeredMessage for the file.     BrokeredMessage largeMessage = new BrokeredMessage(fileStream, true);       Console.WriteLine("Sending: " + AccountDetails.TestFile);     Console.WriteLine("Message body size: " + largeMessage.Size);     Console.WriteLine();         // Send the message with a LargeMessageSender     LargeMessageSender sender = new LargeMessageSender(queueClient);     sender.Send(largeMessage);       // Close the messaging facory.     factory.Close();  } The implementation of the main method of the receiving application is shown below. static void Main(string[] args) {       // Create a token provider with the relevant credentials.     TokenProvider credentials =         TokenProvider.CreateSharedSecretTokenProvider         (AccountDetails.Name, AccountDetails.Key);       // Create a URI for the serivce bus.     Uri serviceBusUri = ServiceBusEnvironment.CreateServiceUri         ("sb", AccountDetails.Namespace, string.Empty);       // Create the MessagingFactory     MessagingFactory factory = MessagingFactory.Create(serviceBusUri, credentials);       // Use the MessagingFactory to create a queue client     QueueClient queueClient = factory.CreateQueueClient(AccountDetails.QueueName);       // Create a LargeMessageReceiver and receive the message.     LargeMessageReceiver receiver = new LargeMessageReceiver(queueClient);     BrokeredMessage largeMessage = receiver.Receive();       Console.WriteLine("Received message");     Console.WriteLine("Message body size: " + largeMessage.Size);       string testFile = AccountDetails.TestFile.Replace(@"\In\", @"\Out\");     Console.WriteLine("Saving file: " + testFile);       // Save the message body as a file.     Stream largeMessageStream = largeMessage.GetBody<Stream>();     largeMessageStream.Seek(0, SeekOrigin.Begin);     FileStream fileOut = new FileStream(testFile, FileMode.Create);     largeMessageStream.CopyTo(fileOut);     fileOut.Close();       Console.WriteLine("Done!"); } In order to test the application, the sending application is executed, which will use the LargeMessageSender class to split the message and place it on the queue. The output of the sender console is shown below. The console shows that the body size of the large message was 9,929,365 bytes, and the message was sent as a sequence of 51 sub messages. When the receiving application is executed the results are shown below. The console application shows that the aggregator has received the 51 messages from the message sequence that was creating in the sending application. The messages have been aggregated to form a massage with a body of 9,929,365 bytes, which is the same as the original large message. The message body is then saved as a file. Improvements to the Implementation The splitter and aggregator patterns in this implementation were created in order to show the usage of the patterns in a demo, which they do quite well. When implementing these patterns in a real-world scenario there are a number of improvements that could be made to the design. Copying Message Header Properties When sending a large message using these classes, it would be great if the message header properties in the message that was received were copied from the message that was sent. The sending application may well add information to the message context that will be required in the receiving application. When the sub messages are created in the splitter, the header properties in the first message could be set to the values in the original large message. The aggregator could then used the values from this first sub message to set the properties in the message header of the large message during the aggregation process. Using Asynchronous Methods The current implementation uses the synchronous send and receive methods of the QueueClient class. It would be much more performant to use the asynchronous methods, however doing so may well affect the sequence in which the sub messages are enqueued, which would require the implementation of a resequencer in the aggregator to restore the correct message sequence. Handling Exceptions In order to keep the code readable no exception handling was added to the implementations. In a real-world scenario exceptions should be handled accordingly.

• Determine arc-length of a Catmull-Rom spline

  - by Wouter

  I have a path that is defined by a concatenation of Catmull-Rom splines. I use the static method Vector2.CatmullRom in XNA that allows for interpolation between points with a value going from 0 to 1. Not every spline in this path has the same length. This causes speed differences if I let the weight go at a constant speed for every spline while proceeding along the path. I can remedy this by letting the speed of the weight be dependent on the length of the spline. How can I determine the length of such a spline? Should I just approximate by cutting the spline into 10 straight lines and sum their lengths? I'm using this for dynamic texture mapping on a generated mesh defined by splines.

• CakePHP Missing Database Table Error

  - by BRADINO

  I am baking a new project management application at work and added a couple new tables to the database today. When I went into the console to bake the new models, they were not in the list... php /path/cake/console/cake.php bake all -app /path/app/ So I manually typed in the model name and I got a missing database table for model error. I checked and double-checked and the database table was named properly. Turns out that some files inside the /app/tmp/cache/ folder were causing Cake not to recognize that I had added new tables to my database. Once I deleted the cache files cake instantly recognized my new database tables and I was baking away! rm -Rf /path/app/tmp/cache/cake*

• How to build Open JavaFX for Android.

  - by PictureCo

  Here's a short recipe for baking JavaFX for Android dalvik. We will need just a few ingredients but each one requires special care. So let's get down to the business.  SourcesThe first ingredient is an open JavaFX repository. This should be piece of cake. As always there's a catch. You probably know that dalvik is jdk6 compatible  and also that certain APIs are missing comparing to good old java vm from Oracle.  Fortunately there is a repository which is a backport of regular OpenJFX to jdk7 and going from jdk7 to jdk6 is possible. The first thing to do is to clone or download the repository from https://bitbucket.org/narya/jfx78. Main page of the project says "It works in some cases" so we will presume that it will work in most cases As I've said dalvik vm misses some APIs which would lead to a build failures. To get them use another compatibility repository which is available on GitHub https://github.com/robovm/robovm-jfx78-compat. Download the zip and unzip sources into jfx78/modules/base.We need also a javafx binary stubs. Use jfxrt.jar from jdk8.The last thing to download are freetype sources from http://freetype.org. These will be necessary for native font rendering. Toolchain setup I have to point out that these instructions were tested only on linux. I suppose they will work with minimal changes also on Mac OS. I also presume that you were able to build open JavaFX. That means all tools like ant, gradle, gcc and jdk8 have been installed and are working all right. In addition to this you will need to download and install jdk7, Android SDK and Android NDK for native code compilation.  Installing all of them will take some time. Don't forget to put them in your path. export ANDROID_SDK=/opt/android-sdk-linux export ANDROID_NDK=/opt/android-ndk-r9b export JAVA_HOME=/opt/jdk1.7.0 export PATH=$JAVA_HOME/bin:$ANDROID_SDK/tools:$ANDROID_SDK/platform-tools:$ANDROID_NDK FreetypeUnzip freetype release sources first. We will have to cross compile them for arm. Firstly we will create a standalone toolchain for cross compiling installed in ~/work/ndk-standalone-19. $ANDROID_NDK/build/tools/make-standalone-toolchain.sh  --platform=android-19 --install-dir=~/work/ndk-standalone-19 After the standalone toolchain has been created cross compile freetype with following script: export TOOLCHAIN=~/work/freetype/ndk-standalone-19 export PATH=$TOOLCHAIN/bin:$PATH export FREETYPE=`pwd` ./configure --host=arm-linux-androideabi --prefix=$FREETYPE/install --without-png --without-zlib --enable-shared sed -i 's/\-version\-info \$(version_info)/-avoid-version/' builds/unix/unix-cc.mk make make install It will compile and install freetype library into $FREETYPE/install. We will link to this install dir later on. It would be possible also to link openjfx font support dynamically against skia library available on Android which already contains freetype. It creates smaller result but can have compatibility problems. Patching Download patches javafx-android-compat.patch + android-tools.patch and patch jfx78 repository. I recommend to have look at patches. First one android-compat.patch updates openjfx build script, removes dependency on SharedSecret classes and updates LensLogger to remove dependency on jdk specific PlatformLogger. Second one android-tools.patch creates helper script in android-tools. The script helps to setup javaFX Android projects. Building Now is time to try the build. Run following script: JAVA_HOME=/opt/jdk1.7.0 JDK_HOME=/opt/jdk1.7.0 ANDROID_SDK=/opt/android-sdk-linux ANDROID_NDK=/opt/android-ndk-r9b PATH=$JAVA_HOME/bin:$ANDROID_SDK/tools:$ANDROID_SDK/platform-tools:$ANDROID_NDK:$PATH gradle -PDEBUG -PDALVIK_VM=true -PBINARY_STUB=~/work/binary_stub/linux/rt/lib/ext/jfxrt.jar \ -PFREETYPE_DIR=~/work/freetype/install -PCOMPILE_TARGETS=android If everything went all right the output is in build/android-sdk Create first JavaFX Android project Use gradle script int android-tools. The script sets the project structure for you.   Following command creates Android HelloWorld project which links to a freshly built javafx runtime and to a HelloWorld application. NAME is a name of Android project. DIR where to create our first project. PACKAGE is package name required by Android. It has nothing to do with a packaging of javafx application. JFX_SDK points to our recently built runtime. JFX_APP points to dist directory of javafx application. (where all application jars sit) JFX_MAIN is fully qualified name of a main class. gradle -PDEBUG -PDIR=/home/user/work -PNAME=HelloWorld -PPACKAGE=com.helloworld \ -PJFX_SDK=/home/user/work/jfx78/build/android-sdk -PJFX_APP=/home/user/NetBeansProjects/HelloWorld/dist \ -PJFX_MAIN=com.helloworld.HelloWorld createProject Now cd to the created project and use it like any other android project. ant clean, debug, uninstall, installd will work. I haven't tried it from any IDE Eclipse nor Netbeans. Special thanks to Stefan Fuchs and Daniel Zwolenski for the repositories used in this blog post.

• Getting WCF Bindings and Behaviors from any config source

  - by cibrax

  The need of loading WCF bindings or behaviors from different sources such as files in a disk or databases is a common requirement when dealing with configuration either on the client side or the service side. The traditional way to accomplish this in WCF is loading everything from the standard configuration section (serviceModel section) or creating all the bindings and behaviors by hand in code. However, there is a solution in the middle that becomes handy when more flexibility is needed. This solution involves getting the configuration from any place, and use that configuration to automatically configure any existing binding or behavior instance created with code.  In order to configure a binding instance (System.ServiceModel.Channels.Binding) that you later inject in any endpoint on the client channel or the service host, you first need to get a binding configuration section from any configuration file (you can generate a temp file on the fly if you are using any other source for storing the configuration).  private BindingsSection GetBindingsSection(string path) { System.Configuration.Configuration config = System.Configuration.ConfigurationManager.OpenMappedExeConfiguration( new System.Configuration.ExeConfigurationFileMap() { ExeConfigFilename = path }, System.Configuration.ConfigurationUserLevel.None); var serviceModel = ServiceModelSectionGroup.GetSectionGroup(config); return serviceModel.Bindings; }   The BindingsSection contains a list of all the configured bindings in the serviceModel configuration section, so you can iterate through all the configured binding that get the one you need (You don’t need to have a complete serviceModel section, a section with the bindings only works).  public Binding ResolveBinding(string name) { BindingsSection section = GetBindingsSection(path); foreach (var bindingCollection in section.BindingCollections) { if (bindingCollection.ConfiguredBindings.Count > 0 && bindingCollection.ConfiguredBindings[0].Name == name) { var bindingElement = bindingCollection.ConfiguredBindings[0]; var binding = (Binding)Activator.CreateInstance(bindingCollection.BindingType); binding.Name = bindingElement.Name; bindingElement.ApplyConfiguration(binding); return binding; } } return null; }   The code above does just that, and also instantiates and configures the Binding object (System.ServiceModel.Channels.Binding) you are looking for. As you can see, the binding configuration element contains a method “ApplyConfiguration” that receives the binding instance that needs to be configured. A similar thing can be done for instance with the “Endpoint” behaviors. You first get the BehaviorsSection, and then, the behavior you want to use.  private BehaviorsSection GetBehaviorsSection(string path) { System.Configuration.Configuration config = System.Configuration.ConfigurationManager.OpenMappedExeConfiguration( new System.Configuration.ExeConfigurationFileMap() { ExeConfigFilename = path }, System.Configuration.ConfigurationUserLevel.None); var serviceModel = ServiceModelSectionGroup.GetSectionGroup(config); return serviceModel.Behaviors; }public List<IEndpointBehavior> ResolveEndpointBehavior(string name) { BehaviorsSection section = GetBehaviorsSection(path); List<IEndpointBehavior> endpointBehaviors = new List<IEndpointBehavior>(); if (section.EndpointBehaviors.Count > 0 && section.EndpointBehaviors[0].Name == name) { var behaviorCollectionElement = section.EndpointBehaviors[0]; foreach (BehaviorExtensionElement behaviorExtension in behaviorCollectionElement) { object extension = behaviorExtension.GetType().InvokeMember("CreateBehavior", BindingFlags.InvokeMethod | BindingFlags.NonPublic | BindingFlags.Instance, null, behaviorExtension, null); endpointBehaviors.Add((IEndpointBehavior)extension); } return endpointBehaviors; } return null; }   In this case, the code for creating the behavior instance is more tricky. First of all, a behavior in the configuration section actually represents a set of “IEndpoint” behaviors, and the behavior element you get from the configuration does not have any public method to configure an existing behavior instance. This last one only contains a protected method “CreateBehavior” that you can use for that purpose. Once you get this code implemented, a client channel can be easily configured as follows  var binding = resolver.ResolveBinding("MyBinding"); var behaviors = resolver.ResolveEndpointBehavior("MyBehavior"); SampleServiceClient client = new SampleServiceClient(binding, new EndpointAddress(new Uri("http://localhost:13749/SampleService.svc"), new DnsEndpointIdentity("localhost"))); foreach (var behavior in behaviors) { if(client.Endpoint.Behaviors.Contains(behavior.GetType())) { client.Endpoint.Behaviors.Remove(behavior.GetType()); } client.Endpoint.Behaviors.Add(behavior); }   The code above assumes that a configuration file (in any place) with a binding “MyBinding” and a behavior “MyBehavior” exists. That file can look like this,  <system.serviceModel> <bindings> <basicHttpBinding> <binding name="MyBinding"> <security mode="Transport"></security> </binding> </basicHttpBinding> </bindings> <behaviors> <endpointBehaviors> <behavior name="MyBehavior"> <clientCredentials> <windows/> </clientCredentials> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel>   The same thing can be done of course in the service host if you want to manually configure the bindings and behaviors.

• aspnet_regiis -lk is not listing the site I need

  - by Luke Duddridge

  I am trying to release a site to run under framework 4 on a server that also hosts framework 2 sites. By default the App has defaulted to framework 2, but when I try to change it's framework to 4 I get a message saying that the following action will cause the iis to reset. The problem I have is there are serveral active sites that I do not want to interupt with a restart. The message goes on to say you can avoid restarting by running the following: aspnet_regiis -norestart -s [IIS Virtual Path] I have been attempting to find the site virtual path but when I run aspnet_regiis -lk the site I am after does not appear to be listed. My first thoughts were that it has something to do with the app pool?, but I'm sure I saw sites that are inactive listed, and after creating a basic site to get it to run under framework 2, the site still did not appear in the -lk list. Can anyone tell me if there is an alternative location to the -lk that I can find the specific information realating to the IIS Virtual Path?

• Referencing environment variables *in* /etc/environment?

  - by Stefan Kendall

  I recently discovered /etc/environment, which seems a more standard way to setup simple environment variables than scripts, but I was wondering if there was a way to back-reference environment variables in the /etc/environment file. That is, I have this: JAVA_HOME="/tools/java" GRAILS_HOME="/tools/grails" GROOVY_HOME="/tools/groovy" GRADLE_HOME="/tools/gradle" PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games" If I try to add $JAVA_HOME/bin to the PATH definition, however, I get $JAVA_HOME/bin, and not the interpolated variable. To remedy this, I'm creating environment.sh in profile.d to add the /bin entries to the path, but this seems sloppy and disorganized. Is there a way to backreference the environment variables in /etc/environment?

• Getting ADB to run

  - by gh0st_h4wk

  I've recently installed ubuntu and I need Android SDK (and subsequently, adb) in order to develop my apps to college. The fact is that, no matter what I do, I can't get adb to work. Exporting its place to the PATH didn't worked. I only get "file or directory not found" error while this are the contents of the PATH variable: renan@RocketQueen:~$ echo $PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/renan/adt/sdk/tools:/home/renan/adt/sdk/platform-tools I don't want to install android-tools-adb/fastboot because they're outdate when compared to SDK Manager ones. What do I need to do in order for it to work from anywhere when called from terminal?
