  • VIM "upgraded" to expandtab and tabstop=8 on Python files

    - by dotancohen
    After reinstalling my OS from Kubuntu 12.10 to Kubuntu 14.04, VIM has changed its behaviour when editing Python files. Though before the reinstall all file types had noexpandtab and tabstop=4 set, now in Python those values are expandtab and tabstop=8, checked also via VIM behaviour and also via asking VIM set foo?. Non-Python files retain the noexpandtab and tabstop=4 behaviour that I prefer. The .vim direcotry and .vimrc were not touched during the reinstall. It can be seen that no files in .vimrc have been touched in months (with the exception of the irrelevant .netrwhist): - bruno():~$ ls -lat ~/.vim total 68 drwxr-xr-x 85 dotancohen dotancohen 12288 Aug 25 13:00 .. drwxr-xr-x 12 dotancohen dotancohen 4096 Aug 21 11:11 . -rw-r--r-- 1 dotancohen dotancohen 268 Aug 21 11:11 .netrwhist drwxr-xr-x 2 dotancohen dotancohen 4096 Mar 6 18:31 plugin drwxr-xr-x 2 dotancohen dotancohen 4096 Mar 6 18:31 doc drwxrwxr-x 2 dotancohen dotancohen 4096 Nov 29 2013 syntax drwxrwxr-x 2 dotancohen dotancohen 4096 Nov 29 2013 ftplugin drwxr-xr-x 4 dotancohen dotancohen 4096 Nov 29 2013 autoload drwxrwxr-x 5 dotancohen dotancohen 4096 May 27 2013 after drwxr-xr-x 2 dotancohen dotancohen 4096 Nov 1 2012 spell -rw------- 1 dotancohen dotancohen 138 Aug 14 2012 .directory -rw-rw-r-- 1 dotancohen dotancohen 190 Jul 3 2012 .VimballRecord drwxrwxr-x 2 dotancohen dotancohen 4096 May 12 2012 colors drwxrwxr-x 2 dotancohen dotancohen 4096 Mar 16 2012 mytags drwxrwxr-x 2 dotancohen dotancohen 4096 Feb 14 2012 keymap Though .vimrc has been touched since the reinstall, it was only me testing to see where the problem is.

  • Server 2012 intermittently fails to respond to pings from single host, even with firewall disabled, but responds to non-ICMP requests fine

    - by James Westbury
    This one is kind of weird. I've got the following machines involved: DC01 - 10.1.2.42, Server 2012, domain controller & DNS server, physical machine nagiosv - 10.1.2.35, CentOS 6.4, Nagios, virtual machine CB01 - 10.1.3.81, Ubuntu 12.04 LTS, couchbase server, virtual machine So, I noticed something was wrong while configuring this new Nagios VM. I started seeing DC01's state flapping. I logged into nagiosv when I saw this happening, and attempted to ping DC01, both by FQDN and its IP address. Neither worked. I tried pinging the machine from CB01, which is another VM on the same virtual switch/physical NIC as nagiosv, and that worked fine. Pings still failing from nagiosv at this time. DC01 is also an internal DNS server, so I ran dig google.com from nagiosv, and was able to run a query against DC01 just fine: ;; Query time: 1 msec ;; SERVER: 10.1.2.42#53(10.1.2.42) ;; WHEN: Fri Nov 1 07:53:51 2013 ;; MSG SIZE rcvd: 204 Pings still failing from nagiosv, though. I can ping from DC01 to nagiosv, and that works, and I can still ping from other VMs on the same physical NIC into DC01, and that works. I should mention at this point that I've disabled the firewall on DC01 for testing purposes, and it doesn't make a damned bit of difference. (Even with the firewall enabled, I have a blanket exception for ICMP from the local subnet, so it shouldn't make a difference, but I figured I should test it anyway.) I loaded up Wireshark on DC01 and pinged it from nagiosv again. What I see is a bunch of echo requests coming in and not a single reply going back out. Filtered results here, showing all ICMP traffic during a 15-second period. A few more bits of info: There are no IP conflicts on the network. MAC addresses on the incoming pings match the MAC on the VM. There are no duplicate MACs on the network, as far as I can see. I have absolutely no idea why DC01 is failing to respond, here. Any ideas?

  • New-ManagedContentSettings - not working properly under Exchange 2010

    - by mfinni
    I have a client that is divesting a business unit into a new AD forest, Exchange org, etc. We're using Quest tools to migrate users and mailboxes. However, I have to build the new infrastructure to match the old one. In the old one, we're using Managed Folder Mailbox Policies to limit (or allow) retention. They started with Exchange 2007 and never upgraded to Retention Policies; oh well. So, in the old environment, when you use a 2007 server to define a new Managed Content Setting, you can pick "Email" from the dropdown for MessageClass. This is a display name; the actual MessageClass values are thus: MessageClass : IPM.Note;IPM.Note.AS/400 Move Notification Form v1.0;IPM.Note.Delayed;IPM.Note.Exchange.ActiveSync.Report;IPM.Note.JournalReport.Msg;IPM.Note.JournalReport.Tnef;IPM.Note.Microsoft.Missed.Voice;IPM.Note.Rules.OofTemplate.Microsoft;IPM.Note.Rules.ReplyTemplate.Microsoft;IPM.Note.Secure.Sign;IPM.Note.SMIME;IPM.Note.SMIME.MultipartSigned;IPM.Note.StorageQuotaWarning;IPM.Note.StorageQuotaWarning.Warning;IPM.Notification.Meeting.Forward;IPM.Outlook.Recall;IPM.Recall.Report.Success;IPM.Schedule.Meeting.*;REPORT.IPM.Note.NDR If I take that and try to mangle it into a new cmdlet for Ex2010 in my new environment here's what I get New-ManagedContentSettings -Name "Delete Messages older then 90 days" -FolderName "Entire Mailbox" -RetentionEnabled $True -AgeLimitForRetention 90 -TriggerForRetention WhenDelivered -RetentionAction DeleteAndAllowRecovery -MessageClass "IPM.Note","IPM.Note.AS/400MoveNotificationFormv1.0","IPM.Note.Delayed","IPM.Note.Exchange.ActiveSync.Report","IPM.Note.JournalReport.Msg","IPM.Note.JournalReport.Tnef","IPM.Note.Microsoft.Missed.Voice","IPM.Note.Rules.OofTemplate.Microsoft","IPM.Note.Rules.ReplyTemplate.Microsoft","IPM.Note.Secure.Sign","IPM.Note.SMIME","IPM.Note.SMIME.MultipartSigned","IPM.Note.StorageQuotaWarning","IPM.Note.StorageQuotaWarning.Warning","IPM.Notification.Meeting.Forward","IPM.Outlook.Recall","IPM.Recall.Report.Success","IPM.Schedule.Meeting.*","REPORT.IPM.Note.NDR" -whatif Invoke-Command : Cannot bind parameter 'MessageClass' to the target. Exception setting "MessageClass": "The length of t he property is too long. The maximum length is 255 and the length of the value provided is 518." At C:\Users\MFinnigan.sa\AppData\Roaming\Microsoft\Exchange\RemotePowerShell\pfexcas02.fve.ad.5ssl.com\pfexcas02.fve.ad .5ssl.com.psm1:28204 char:29 + $scriptCmd = { & <<<< $script:InvokeCommand ` + CategoryInfo : WriteError: (:) [New-ManagedContentSettings], ParameterBindingException + FullyQualifiedErrorId : ParameterBindingFailed,Microsoft.Exchange.Management.SystemConfigurationTasks.NewManaged ContentSettings So, the config object can store all that mess, but I can't fit it in through the cmdlet to create the object. Lovely. Any ideas?

  • What is the difference between running a Windows service vs. running through shell?

    - by Zack
    I am trying to troubleshoot an issue on a Windows 2008 server where running attempting to connect to a "Timberline Data Source" ODBC driver crashes if the call is in a "service" context, but succeeds if the call is initiated manually in a Remote Desktop session. I have set the service to run as my user. I'm wondering if, all else being equal (user, machine, etc), are there any fundamental security/environment differences between running a process as a service vs manually? --- Implementation Details --- In case it is helpful for anyone, I had a system that started as an attempt to connect to a Timberline Database using ODBC and a Python CGI script called via IIS 7. The script itself works fine, however, as soon as I attempt to perform the ODBC connect function, the script crashes without throwing an exception. The script was able to connect fine when executed via command line. The same thing happened when using a C#/.net service, attempting to run via Apache, Windows Scheduler or even a 3rd party scheduling tool. With the last option (the 3rd party scheduling tool, pycron) I set the service up log in as my user and had the same issue (I confirmed via Task Manager that the process running user was, in fact, me). It just doesn't make sense to me why a service, which should be running as my user, appears to still be operating in a different security context or environment. Also, if it's important, the Timberline database is referenced by computer name on the network ("\\timberline-server\Timberline Office\Accounts\AT" or something to that effect) I also realized that, as Joel pointed out, the server DOES have a mapped drive ("Y:" which is mapped to "\\timberline-server\Timberline Office") The DSN is set up at the "System DSN" level which, according to the ODBC Administration Tool, means that the DSN is available to users and services Since I'm not allowed to answer this question yet, I'll post the solution that I arrived on: As Joel Coel mentioned, there actually was a mapped drive scenario. I didn't realize this because the DSN specified a path using UNC. However, it seems as though the actual Timberline Driver referred to a mapped drive. Since services don't start with the mapped drive, I was forced to add the drive mapping code into my service. Since it was written in python, I used code from a Stackoverflow answer that was able to map the drive on the fly.

  • Bridging and iptables SNAT conflict

    - by sad_admin
    Hello I am working on a setup here and have it working with one minor exception. Devices on one side of my bridge aren't getting SNAT'd to the Internet. The Diagram / Overview: Primary_Network (Site_A) | | Internet ------- Linux_Bridge_GW (GW) | | Secondary/CoLo Site (Site_B) Here is the setup: 1.) Site_A has all the production servers and workstations. 2.) Site_B has a set of servers that we would like to fail-over to and also serve our internet facing services from. 3.) GW has two interfaces that are trunked and carrying the appropriate VLAN traffic (allow layer-2 propagation of traffic between sites) //this all works perfectly fine. 4.) The problem that is being encountered is, hosts from Site_B have their default GW at Site_A (same subnet) GW does not have IPs on the VLANs that are being passed. 5.) All hosts at Site_A can reach the Internet without problem. 6.) GW has an addresses on a subnet that is ONLY for Internet destined traffic. (This was done so that Websense would not have to parse unnecessary traffic. We use this VLAN as the monitor port's source on the switch where Websense is sitting). What I think is happening: 1.) Packet/Frame comes in on physdev at Site_B destined for Internet. 2.) Kernel sees packet, and forwards it out the other side of the bridge to that host's default GW. 3.) Site_A (containing core-network's Default-GW) sees that packet is destined for a host it doesn't know about, so it sends it to it's default GW (the linux bridge, since it's Internet bound). 4.) The kernel says "Hey, I've seen you before" and therefore doesn't do SNAT'ing on the packet and sends it out to the Internet where it's black-holed. Why I think it's happening: 1.) A tcpdump on the internet facing NIC shows the packet leaving the interface with the private address as it's source. What I would like: 1.) Have the packet SNAT'd. 2.) Something like the below would be awesome a.) packet comes in from Site_B b.) kernel sees that the packet is NOT destined for itself or any private address c.) kernel says "OK, well since you're destined for the Internet I'm going to send you out this interface rather than forward you to your normal default GW that's WAAAY over there." d.) packet comes in from internet and is sent out the appropriate bridge physdev depending on which site the host it's destined for is at. Thanks for any assistance or guidance that you are willing to offer. Best Regards, Sad Admin

  • Installing Lubuntu 14.04.1 fails, upowerd appears to hang

    - by Rantanplan
    On the live-CD session, I tried installing Lubuntu double clicking on the install button on the desktop. Here, the CD starts running but then stops running and nothing happens. Next, I rebooted and tried installing Lubuntu directly from the boot menu screen using forcepae again. After a while, I receive the following error message: The installer encountered an unrecoverable error. A desktop session will now be run so that you may investigate the problem or try installing again. Hitting Enter brings me to the desktop. For what errors should I search? And how?

  • C# 5 Async, Part 1: Simplifying Asynchrony – That for which we await

    - by Reed
    Today’s announcement at PDC of the future directions C# is taking excite me greatly.  The new Visual Studio Async CTP is amazing.  Asynchronous code – code which frustrates and demoralizes even the most advanced of developers, is taking a huge leap forward in terms of usability.  This is handled by building on the Task functionality in .NET 4, as well as the addition of two new keywords being added to the C# language: async and await. This core of the new asynchronous functionality is built upon three key features.  First is the Task functionality in .NET 4, and based on Task and Task<TResult>.  While Task was intended to be the primary means of asynchronous programming with .NET 4, the .NET Framework was still based mainly on the Asynchronous Pattern and the Event-based Asynchronous Pattern. The .NET Framework added functionality and guidance for wrapping existing APIs into a Task based API, but the framework itself didn’t really adopt Task or Task<TResult> in any meaningful way.  The CTP shows that, going forward, this is changing. One of the three key new features coming in C# is actually a .NET Framework feature.  Nearly every asynchronous API in the .NET Framework has been wrapped into a new, Task-based method calls.  In the CTP, this is done via as external assembly (AsyncCtpLibrary.dll) which uses Extension Methods to wrap the existing APIs.  However, going forward, this will be handled directly within the Framework.  This will have a unifying effect throughout the .NET Framework.  This is the first building block of the new features for asynchronous programming: Going forward, all asynchronous operations will work via a method that returns Task or Task<TResult> The second key feature is the new async contextual keyword being added to the language.  The async keyword is used to declare an asynchronous function, which is a method that either returns void, a Task, or a Task<T>. Inside the asynchronous function, there must be at least one await expression.  This is a new C# keyword (await) that is used to automatically take a series of statements and break it up to potentially use discontinuous evaluation.  This is done by using await on any expression that evaluates to a Task or Task<T>. For example, suppose we want to download a webpage as a string.  There is a new method added to WebClient: Task<string> WebClient.DownloadStringTaskAsync(Uri).  Since this returns a Task<string> we can use it within an asynchronous function.  Suppose, for example, that we wanted to do something similar to my asynchronous Task example – download a web page asynchronously and check to see if it supports XHTML 1.0, then report this into a TextBox.  This could be done like so: private async void button1_Click(object sender, RoutedEventArgs e) { string url = "http://reedcopsey.com"; string content = await new WebClient().DownloadStringTaskAsync(url); this.textBox1.Text = string.Format("Page {0} supports XHTML 1.0: {1}", url, content.Contains("XHTML 1.0")); } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Let’s walk through what’s happening here, step by step.  By adding the async contextual keyword to the method definition, we are able to use the await keyword on our WebClient.DownloadStringTaskAsync method call. When the user clicks this button, the new method (Task<string> WebClient.DownloadStringTaskAsync(string)) is called, which returns a Task<string>.  By adding the await keyword, the runtime will call this method that returns Task<string>, and execution will return to the caller at this point.  This means that our UI is not blocked while the webpage is downloaded.  Instead, the UI thread will “await” at this point, and let the WebClient do it’s thing asynchronously. When the WebClient finishes downloading the string, the user interface’s synchronization context will automatically be used to “pick up” where it left off, and the Task<string> returned from DownloadStringTaskAsync is automatically unwrapped and set into the content variable.  At this point, we can use that and set our text box content. There are a couple of key points here: Asynchronous functions are declared with the async keyword, and contain one or more await expressions In addition to the obvious benefits of shorter, simpler code – there are some subtle but tremendous benefits in this approach.  When the execution of this asynchronous function continues after the first await statement, the initial synchronization context is used to continue the execution of this function.  That means that we don’t have to explicitly marshal the call that sets textbox1.Text back to the UI thread – it’s handled automatically by the language and framework!  Exception handling around asynchronous method calls also just works. I’d recommend every C# developer take a look at the documentation on the new Asynchronous Programming for C# and Visual Basic page, download the Visual Studio Async CTP, and try it out.

  • Enable Automatic Code First Migrations On SQL Database in Azure Web Sites

    - by Steve Michelotti
    Now that Azure supports .NET Framework 4.5, you can use all the latest and greatest available features. A common scenario is to be able to use Entity Framework Code First Migrations with a SQL Database in Azure. Prior to Code First Migrations, Entity Framework provided database initializers. While convenient for demos and prototypes, database initializers weren’t useful for much beyond that because, if you delete and re-create your entire database when the schema changes, you lose all of your operational data. This is the void that Migrations are meant to fill. For example, if you add a column to your model, Migrations will alter the database to add the column rather than blowing away the entire database and re-creating it from scratch. Azure is becoming increasingly easier to use – especially with features like Azure Web Sites. Being able to use Entity Framework Migrations in Azure makes deployment easier than ever. In this blog post, I’ll walk through enabling Automatic Code First Migrations on Azure. I’ll use the Simple Membership provider for my example. First, we’ll create a new Azure Web site called “migrationstest” including creating a new SQL Database along with it:   Next we’ll go to the web site and download the publish profile:   In the meantime, we’ve created a new MVC 4 website in Visual Studio 2012 using the “Internet Application” template. This template is automatically configured to use the Simple Membership provider. We’ll do our initial Publish to Azure by right-clicking our project and selecting “Publish…”. From the “Publish Web” dialog, we’ll import the publish profile that we downloaded in the previous step:   Once the site is published, we’ll just click the “Register” link from the default site. Since the AccountController is decorated with the [InitializeSimpleMembership] attribute, the initializer will be called and the initial database is created.   We can verify this by connecting to our SQL Database on Azure with SQL Management Studio (after making sure that our local IP address is added to the list of Allowed IP Addresses in Azure): One interesting note is that these tables got created with the default Entity Framework initializer – which is to create the database if it doesn’t already exist. However, our database did already exist! This is because there is a new feature of Entity Framework 5 where Code First will add tables to an existing database as long as the target database doesn’t contain any of the tables from the model. At this point, it’s time to enable Migrations. We’ll open the Package Manger Console and execute the command: PM> Enable-Migrations -EnableAutomaticMigrations This will enable automatic migrations for our project. Because we used the "-EnableAutomaticMigrations” switch, it will create our Configuration class with a constructor that sets the AutomaticMigrationsEnabled property set to true: 1: public Configuration() 2: { 3: AutomaticMigrationsEnabled = true; 4: } We’ll now add our initial migration: PM> Add-Migration Initial This will create a migration class call “Initial” that contains the entire model. But we need to remove all of this code because our database already exists so we are just left with empty Up() and Down() methods. 1: public partial class Initial : DbMigration 2: { 3: public override void Up() 4: { 5: } 6: 7: public override void Down() 8: { 9: } 10: } If we don’t remove this code, we’ll get an exception the first time we attempt to run migrations that tells us: “There is already an object named 'UserProfile' in the database”. This blog post by Julie Lerman fully describes this scenario (i.e., enabling migrations on an existing database). Our next step is to add the Entity Framework initializer that will automatically use Migrations to update the database to the latest version. We will add these 2 lines of code to the Application_Start of the Global.asax: 1: Database.SetInitializer(new MigrateDatabaseToLatestVersion<UsersContext, Configuration>()); 2: new UsersContext().Database.Initialize(false); Note the Initialize() call will force the initializer to run if it has not been run before. At this point, we can publish again to make sure everything is still working as we are expecting. This time we’re going to specify in our publish profile that Code First Migrations should be executed:   Once we have re-published we can once again navigate to the Register page. At this point the database has not been changed but Migrations is now enabled on our SQL Database in Azure. We can now customize our model. Let’s add 2 new properties to the UserProfile class – Email and DateOfBirth: 1: [Table("UserProfile")] 2: public class UserProfile 3: { 4: [Key] 5: [DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)] 6: public int UserId { get; set; } 7: public string UserName { get; set; } 8: public string Email { get; set; } 9: public DateTime DateOfBirth { get; set; } 10: } At this point all we need to do is simply re-publish. We’ll once again navigate to the Registration page and, because we had Automatic Migrations enabled, the database has been altered (*not* recreated) to add our 2 new columns. We can verify this by once again looking at SQL Management Studio:   Automatic Migrations provide a quick and easy way to keep your database in sync with your model without the worry of having to re-create your entire database and lose data. With Azure Web Sites you can set up automatic deployment with Git or TFS and automate the entire process to make it dead simple.

  • Session Report: What’s New in JSF: A Complete Tour of JSF 2.2

    - by Janice J. Heiss
    On Wednesday, Ed Burns, Consulting Staff Member at Oracle, presented a session, CON3870 -- “What’s New in JSF: A Complete Tour of JSF 2.2,” in which he provided an update on recent developments in JavaServer Faces 2.2. He began by emphasizing that, “JavaServer Faces 2.2 continues the evolution of the Java EE standard user interface technology. Like previous releases, this iteration is very community-driven and transparent.” He pointed out that since JSF was introduced at the 2001 JavaOne Keynote, it has had a long and successful run and has found a home in applications where the UI logic resides entirely on the server where the model and UI logic is. In such cases, the browser performs fairly simple functions. However, developers can take advantage of the power of browsers, something that Project Avatar is focused on by letting developers author their applications so the UI logic is running on the client and communicating to the back end via RESTful web services. “Most importantly,” remarked Burns, “JSF 2.2 offers a really good migration path because even in the scope of one application you could have an app written with JSF that has its UI logic on the server and, on a gradual basis, you could migrate parts of the app over to use client-side technologies. This can be done at any level of granularity – per page or per collection of pages. It all depends on what you want to do.” His presentation, which focused on the basic new features of JSF 2.2, began by restating the scope of JSF and encouraged attendees to check out Roger Kitain’s session: CON5133 “Techniques for Responsive Real-Time Web UIs.” Burns explained that JSF has endured because, “We still need web apps that are maintainable, localizable, quick to build, accessible, secure, look great and are fun to use.” It is used on every continent – the curious can go here to check out where its unofficial usage is tracked. He emphasized the significance of the UI logic being substantially on the server. This: Separates Component Semantics from Rendering, Allows components to “own” their little patch of the UI -- encode/decode, And offers a well-defined lifecycle: Inversion of Control. Burns reminded attendees that JSR-344, the spec for JSF 2.2, is now on Java Community Process 2.8, a revised version of the JCP that allows for more openness and transparency. He then offered some tools for community access to JSF 2.2:    * Public java.net projects spec http://jsf-spec.java.net/ impl http://jsf.java.net/ Open Source: GPL+Classpath Exception    * Mailing Lists [email protected]                                Public readable archive, JSPA signed member read/write [email protected]                                     Public readable archive, any java.net member read/write                         All mail sent to jsr344-experts is sent to users. * Issue Tracker spec http://jsf-spec.java.net/issues/ impl http://jsf.java.net/issues/ JSF 2.2, which is JSR 344, has a Public Review Draft planned by December 2012 with no need for a Renewal Ballot. The Early Draft Review of JSR 344 was published on December 8, 2011. Interested developers are encouraged to offer their input. Six Big Ticket Features of JSF 2.2 Burns summarized the six big ticket features of JSF 2.2:* HTML5 Friendly Markup Support Pass through attributes and elements * Faces Flows* Cross Site Request Forgery Protection* Loading Facelets via ResourceHandler* File Upload Component* Multi-Templating He explained that he called it “HTML 5 friendly” because there is really nothing HTML 5 specific about it -- it could be 4. But it enables developers to use new elements that are present in HTML5 without having a JSF component library that is written to take advantage of those specifically. It gives the page author the ability to use plain HTML5 to write their page, but to still take advantage of the server-side available in JSF. He presented a demo showing JSF 2.2’s ability to leverage the expressiveness of HTML5. Burns then explained the significance of face flows, which offer function points and quantify how much work has taken place, something of great value to JSF users. He went on to talk about JSF 2.2.’s cross-site request forgery protection (CSRF) and offered details about how it protects applications against attack. Then he talked about JSF 2.2’s File Upload Component and explained that the final specification will have Ajax and non-Ajax support. The current milestone has non-Ajax support implemented. He then went on to explain its capacity to add facelets through ResourceHandler. Previously, JSF 2.0 added Facelets and ResourceHandler as disparate units; now in JSF 2.2 the two concepts are unified. Finally, he explained the concept of multi-templating in JSF 2.2 and went on to discuss more medium-level features of the release. For an easy, low maintenance way of staying in touch with JSF developments go to JSF’s Twitter page where every month or so, important updates are offered.

  • SmtpClient and Locked File Attachments

    - by Rick Strahl
    Got a note a couple of days ago from a client using one of my generic routines that wraps SmtpClient. Apparently whenever a file has been attached to a message and emailed with SmtpClient the file remains locked after the message has been sent. Oddly this particular issue hasn’t cropped up before for me although these routines are in use in a number of applications I’ve built. The wrapper I use was built mainly to backfit an old pre-.NET 2.0 email client I built using Sockets to avoid the CDO nightmares of the .NET 1.x mail client. The current class retained the same class interface but now internally uses SmtpClient which holds a flat property interface that makes it less verbose to send off email messages. File attachments in this interface are handled by providing a comma delimited list for files in an Attachments string property which is then collected along with the other flat property settings and eventually passed on to SmtpClient in the form of a MailMessage structure. The jist of the code is something like this: /// <summary> /// Fully self contained mail sending method. Sends an email message by connecting /// and disconnecting from the email server. /// </summary> /// <returns>true or false</returns> public bool SendMail() { if (!this.Connect()) return false; try { // Create and configure the message MailMessage msg = this.GetMessage(); smtp.Send(msg); this.OnSendComplete(this); } catch (Exception ex) { string msg = ex.Message; if (ex.InnerException != null) msg = ex.InnerException.Message; this.SetError(msg); this.OnSendError(this); return false; } finally { // close connection and clear out headers // SmtpClient instance nulled out this.Close(); } return true; } /// <summary> /// Configures the message interface /// </summary> /// <param name="msg"></param> protected virtual MailMessage GetMessage() { MailMessage msg = new MailMessage(); msg.Body = this.Message; msg.Subject = this.Subject; msg.From = new MailAddress(this.SenderEmail, this.SenderName); if (!string.IsNullOrEmpty(this.ReplyTo)) msg.ReplyTo = new MailAddress(this.ReplyTo); // Send all the different recipients this.AssignMailAddresses(msg.To, this.Recipient); this.AssignMailAddresses(msg.CC, this.CC); this.AssignMailAddresses(msg.Bcc, this.BCC); if (!string.IsNullOrEmpty(this.Attachments)) { string[] files = this.Attachments.Split(new char[2] { ',', ';' }, StringSplitOptions.RemoveEmptyEntries); foreach (string file in files) { msg.Attachments.Add(new Attachment(file)); } } if (this.ContentType.StartsWith("text/html")) msg.IsBodyHtml = true; else msg.IsBodyHtml = false; msg.BodyEncoding = this.Encoding; … additional code omitted return msg; } Basically this code collects all the property settings of the wrapper object and applies them to the SmtpClient and in GetMessage() to an individual MailMessage properties. Specifically notice that attachment filenames are converted from a comma-delimited string to filenames from which new attachments are created. The code as it’s written however, will cause the problem with file attachments not being released properly. Internally .NET opens up stream handles and reads the files from disk to dump them into the email send stream. The attachments are always sent correctly but the local files are not immediately closed. As you probably guessed the issue is simply that some resources are not automatcially disposed when sending is complete and sure enough the following code change fixes the problem: // Create and configure the message using (MailMessage msg = this.GetMessage()) { smtp.Send(msg); if (this.SendComplete != null) this.OnSendComplete(this); // or use an explicit msg.Dispose() here } The Message object requires an explicit call to Dispose() (or a using() block as I have here) to force the attachment files to get closed. I think this is rather odd behavior for this scenario however. The code I use passes in filenames and my expectation of an API that accepts file names is that it uses the files by opening and streaming them and then closing them when done. Why keep the streams open and require an explicit .Dispose() by the calling code which is bound to lead to unexpected behavior just as my customer ran into? Any API level code should clean up as much as possible and this is clearly not happening here resulting in unexpected behavior. Apparently lots of other folks have run into this before as I found based on a few Twitter comments on this topic. Odd to me too is that SmtpClient() doesn’t implement IDisposable – it’s only the MailMessage (and Attachments) that implement it and require it to clean up for left over resources like open file handles. This means that you couldn’t even use a using() statement around the SmtpClient code to resolve this – instead you’d have to wrap it around the message object which again is rather unexpected. Well, chalk that one up to another small unexpected behavior that wasted a half an hour of my time – hopefully this post will help someone avoid this same half an hour of hunting and searching.

  • Updating the managed debugging API for .NET v4

    - by Brian Donahue
    In any successful investigation, the right tools play a big part in collecting evidence about the state of the "crime scene" as it was before the detectives arrived. Unfortunately for the Crash Scene Investigator, we don't have the budget to fly out to the customer's site, chalk the outline, and eat their doughnuts. We have to rely on the end-user to collect the evidence for us, which means giving them the fingerprint dust and the evidence baggies and leaving them to it. With that in mind, the Red Gate support team have been writing tools that can collect vital clues with a minimum of fuss. Years ago we would have asked for a memory dump, where we used to get the customer to run CDB.exe and produce dumps that we could analyze in-house, but those dumps were pretty unwieldy (500MB files) and the debugger often didn't dump exactly where we wanted, or made five or more dumps. What we wanted was just the minimum state information from the program at the time of failure, so we produced a managed debugger that captured every first and second-chance exception and logged the stack and a minimal amount of variables from the memory of the application, which could all be exported as XML. This caused less inconvenience to the end-user because it is much easier to send a 65KB XML file in an email than a 500MB file containing all of the application's memory. We don't need to have the entire victim shipped out to us when we just want to know what was under the fingernails. The thing that made creating a managed debugging tool possible was the MDbg Engine example written by Microsoft as part of the Debugging Tools for Windows distribution. Since the ICorDebug interface is a bit difficult to understand, they had kindly created some wrappers that provided an event-driven debugging model that was perfect for our needs, but .NET 4 applications under debugging started complaining that "The debugger's protocol is incompatible with the debuggee". The introduction of .NET Framework v4 had changed the managed debugging API significantly, however, without an update for the MDbg Engine code! After a few hours of research, I had finally worked out that most of the version 4 ICorDebug interface still works much the same way in "legacy" v2 mode and there was a relatively easy fix for the problem in that you can still get a reference to legacy ICorDebug by changing the way the interface is created. In .NET v2, the interface was acquired using the CreateDebuggingInterfaceFromVersion method in mscoree.dll. In v4, you must first create IClrMetaHost, enumerate the runtimes, get an ICLRRuntimeInfo interface to the .NET 4 runtime from that, and use the GetInterface method in mscoree.dll to return a "legacy" ICorDebug interface. The rest of the MDbg Engine will continue working the old way. Here is how I had changed the MDbg Engine code to support .NET v4: private void InitFromVersion(string debuggerVersion){if( debuggerVersion.StartsWith("v1") ){throw new ArgumentException( "Can't debug a version 1 CLR process (\"" + debuggerVersion + "\"). Run application in a version 2 CLR, or use a version 1 debugger instead." );} ICorDebug rawDebuggingAPI=null;if (debuggerVersion.StartsWith("v4")){Guid CLSID_MetaHost = new Guid("9280188D-0E8E-4867-B30C-7FA83884E8DE"); Guid IID_MetaHost = new Guid("D332DB9E-B9B3-4125-8207-A14884F53216"); ICLRMetaHost metahost = (ICLRMetaHost)NativeMethods.ClrCreateInterface(CLSID_MetaHost, IID_MetaHost); IEnumUnknown runtimes = metahost.EnumerateInstalledRuntimes(); ICLRRuntimeInfo runtime = GetRuntime(runtimes, debuggerVersion); //Defined in metahost.hGuid CLSID_CLRDebuggingLegacy = new Guid(0xDF8395B5, 0xA4BA, 0x450b, 0xA7, 0x7C, 0xA9, 0xA4, 0x77, 0x62, 0xC5, 0x20);Guid IID_ICorDebug = new Guid("3D6F5F61-7538-11D3-8D5B-00104B35E7EF"); Object res;runtime.GetInterface(ref CLSID_CLRDebuggingLegacy, ref IID_ICorDebug, out res); rawDebuggingAPI = (ICorDebug)res; }elserawDebuggingAPI = NativeMethods.CreateDebuggingInterfaceFromVersion((int)CorDebuggerVersion.Whidbey,debuggerVersion);if (rawDebuggingAPI != null)InitFromICorDebug(rawDebuggingAPI);elsethrow new ArgumentException("Support for debugging version " + debuggerVersion + " is not yet implemented");} The changes above will ensure that the debugger can support .NET Framework v2 and v4 applications with the same codebase, but we do compile two different applications: one targeting v2 and the other v4. As a footnote I need to add that some missing native methods and wrappers, along with the EnumerateRuntimes method code, came from the Mindbg project on Codeplex. Another change is that when using the MDbgEngine.CreateProcess to launch a process in the debugger, do not supply a null as the final argument. This does not work any more because GetCORVersion always returns "v2.0.50727" as the function has been deprecated in .NET v4. What's worse is that on a system with only .NET 4, the user will be prompted to download and install .NET v2! Not nice! This works much better: proc = m_Debugger.CreateProcess(ProcessName, ProcessArgs, DebugModeFlag.Default,String.Format("v{0}.{1}.{2}",System.Environment.Version.Major,System.Environment.Version.Minor,System.Environment.Version.Build)); Microsoft "unofficially" plan on updating the MDbg samples soon, but if you have an MDbg-based application, you can get it working right now by changing one method a bit and adding a few new interfaces (ICLRMetaHost, IEnumUnknown, and ICLRRuntimeInfo). The new, non-legacy implementation of MDbg Engine will add new, interesting features like dump-file support and by association I assume garbage-collection/managed object stats, so it will be well worth looking into if you want to extend the functionality of a managed debugger going forward.

  • SQL SERVER – Beginning of SQL Server Architecture – Terminology – Guest Post

    - by pinaldave
    SQL Server Architecture is a very deep subject. Covering it in a single post is an almost impossible task. However, this subject is very popular topic among beginners and advanced users.  I have requested my friend Anil Kumar who is expert in SQL Domain to help me write  a simple post about Beginning SQL Server Architecture. As stated earlier this subject is very deep subject and in this first article series he has covered basic terminologies. In future article he will explore the subject further down. Anil Kumar Yadav is Trainer, SQL Domain, Koenig Solutions. Koenig is a premier IT training firm that provides several IT certifications, such as Oracle 11g, Server+, RHCA, SQL Server Training, Prince2 Foundation etc. In this Article we will discuss about MS SQL Server architecture. The major components of SQL Server are: Relational Engine Storage Engine SQL OS Now we will discuss and understand each one of them. 1) Relational Engine: Also called as the query processor, Relational Engine includes the components of SQL Server that determine what your query exactly needs to do and the best way to do it. It manages the execution of queries as it requests data from the storage engine and processes the results returned. Different Tasks of Relational Engine: Query Processing Memory Management Thread and Task Management Buffer Management Distributed Query Processing 2) Storage Engine: Storage Engine is responsible for storage and retrieval of the data on to the storage system (Disk, SAN etc.). to understand more, let’s focus on the following diagram. When we talk about any database in SQL server, there are 2 types of files that are created at the disk level – Data file and Log file. Data file physically stores the data in data pages. Log files that are also known as write ahead logs, are used for storing transactions performed on the database. Let’s understand data file and log file in more details: Data File: Data File stores data in the form of Data Page (8KB) and these data pages are logically organized in extents. Extents: Extents are logical units in the database. They are a combination of 8 data pages i.e. 64 KB forms an extent. Extents can be of two types, Mixed and Uniform. Mixed extents hold different types of pages like index, System, Object data etc. On the other hand, Uniform extents are dedicated to only one type. Pages: As we should know what type of data pages can be stored in SQL Server, below mentioned are some of them: Data Page: It holds the data entered by the user but not the data which is of type text, ntext, nvarchar(max), varchar(max), varbinary(max), image and xml data. Index: It stores the index entries. Text/Image: It stores LOB ( Large Object data) like text, ntext, varchar(max), nvarchar(max),  varbinary(max), image and xml data. GAM & SGAM (Global Allocation Map & Shared Global Allocation Map): They are used for saving information related to the allocation of extents. PFS (Page Free Space): Information related to page allocation and unused space available on pages. IAM (Index Allocation Map): Information pertaining to extents that are used by a table or index per allocation unit. BCM (Bulk Changed Map): Keeps information about the extents changed in a Bulk Operation. DCM (Differential Change Map): This is the information of extents that have modified since the last BACKUP DATABASE statement as per allocation unit. Log File: It also known as write ahead log. It stores modification to the database (DML and DDL). Sufficient information is logged to be able to: Roll back transactions if requested Recover the database in case of failure Write Ahead Logging is used to create log entries Transaction logs are written in chronological order in a circular way Truncation policy for logs is based on the recovery model SQL OS: This lies between the host machine (Windows OS) and SQL Server. All the activities performed on database engine are taken care of by SQL OS. It is a highly configurable operating system with powerful API (application programming interface), enabling automatic locality and advanced parallelism. SQL OS provides various operating system services, such as memory management deals with buffer pool, log buffer and deadlock detection using the blocking and locking structure. Other services include exception handling, hosting for external components like Common Language Runtime, CLR etc. I guess this brief article gives you an idea about the various terminologies used related to SQL Server Architecture. In future articles we will explore them further. Guest Author  The author of the article is Anil Kumar Yadav is Trainer, SQL Domain, Koenig Solutions.

  • Azure &ndash; Part 6 &ndash; Blob Storage Service

    - by Shaun
    When migrate your application onto the Azure one of the biggest concern would be the external files. In the original way we understood and ensure which machine and folder our application (website or web service) is located in. So that we can use the MapPath or some other methods to read and write the external files for example the images, text files or the xml files, etc. But things have been changed when we deploy them on Azure. Azure is not a server, or a single machine, it’s a set of virtual server machine running under the Azure OS. And even worse, your application might be moved between thses machines. So it’s impossible to read or write the external files on Azure. In order to resolve this issue the Windows Azure provides another storage serviec – Blob, for us. Different to the table service, the blob serivce is to be used to store text and binary data rather than the structured data. It provides two types of blobs: Block Blobs and Page Blobs. Block Blobs are optimized for streaming. They are comprised of blocks, each of which is identified by a block ID and each block can be a maximum of 4 MB in size. Page Blobs are are optimized for random read/write operations and provide the ability to write to a range of bytes in a blob. They are a collection of pages. The maximum size for a page blob is 1 TB.   In the managed library the Azure SDK allows us to communicate with the blobs through these classes CloudBlobClient, CloudBlobContainer, CloudBlockBlob and the CloudPageBlob. Similar with the table service managed library, the CloudBlobClient allows us to reach the blob service by passing our storage account information and also responsible for creating the blob container is not exist. Then from the CloudBlobContainer we can save or load the block blobs and page blobs into the CloudBlockBlob and the CloudPageBlob classes.   Let’s improve our exmaple in the previous posts – add a service method allows the user to upload the logo image. In the server side I created a method name UploadLogo with 2 parameters: email and image. Then I created the storage account from the config file. I also add the validation to ensure that the email passed in is valid. 1: var storageAccount = CloudStorageAccount.FromConfigurationSetting("DataConnectionString"); 2: var accountContext = new DynamicDataContext<Account>(storageAccount); 3:  4: // validation 5: var accountNumber = accountContext.Load() 6: .Where(a => a.Email == email) 7: .ToList() 8: .Count; 9: if (accountNumber <= 0) 10: { 11: throw new ApplicationException(string.Format("Cannot find the account with the email {0}.", email)); 12: } Then there are three steps for saving the image into the blob service. First alike the table service I created the container with a unique name and create it if it’s not exist. 1: // create the blob container for account logos if not exist 2: CloudBlobClient blobStorage = storageAccount.CreateCloudBlobClient(); 3: CloudBlobContainer container = blobStorage.GetContainerReference("account-logo"); 4: container.CreateIfNotExist(); Then, since in this example I will just send the blob access URL back to the client so I need to open the read permission on that container. 1: // configure blob container for public access 2: BlobContainerPermissions permissions = container.GetPermissions(); 3: permissions.PublicAccess = BlobContainerPublicAccessType.Container; 4: container.SetPermissions(permissions); And at the end I combine the blob resource name from the input file name and Guid, and then save it to the block blob by using the UploadByteArray method. Finally I returned the URL of this blob back to the client side. 1: // save the blob into the blob service 2: string uniqueBlobName = string.Format("{0}_{1}.jpg", email, Guid.NewGuid().ToString()); 3: CloudBlockBlob blob = container.GetBlockBlobReference(uniqueBlobName); 4: blob.UploadByteArray(image); 5:  6: return blob.Uri.ToString(); Let’s update a bit on the client side application and see the result. Here I just use my simple console application to let the user input the email and the file name of the image. If it’s OK it will show the URL of the blob on the server side so that we can see it through the web browser. Then we can see the logo I’ve just uploaded through the URL here. You may notice that the blob URL was based on the container name and the blob unique name. In the document of the Azure SDK there’s a page for the rule of naming them, but I think the simple rule would be – they must be valid as an URL address. So that you cannot name the container with dot or slash as it will break the ADO.Data Service routing rule. For exmaple if you named the blob container as Account.Logo then it will throw an exception says 400 Bad Request.   Summary In this short entity I covered the simple usage of the blob service to save the images onto Azure. Since the Azure platform does not support the file system we have to migrate our code for reading/writing files to the blob service before deploy it to Azure. In order to reducing this effort Microsoft provided a new approch named Drive, which allows us read and write the NTFS files just likes what we did before. It’s built up on the blob serivce but more properly for files accessing. I will discuss more about it in the next post.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind. Copyright © Shaun Ziyan Xu.

  • 2010 Collaboration Summit Impressions

    - by Elena Zannoni
    It's a bit late, but there you have it anyway. April 14 to 16 I attended the Linux Foundation Collaboration Summit in SFO. I was running two tracks, one on tracing and one on tools. You can see the tracks and the slides here: http://events.linuxfoundation.org/events/collaboration-summit/slides I was pretty busy both days, Thursday with a whole day tracing track, Friday with a half day toolchain track. The sessions were well attended, the rooms were full, with people spilling in the hallways. Some new things were presented, like Kernelshark, by Steve Rostedt, a GUI (yes, believe it or not, a GUI) written in GTK. It is very nice, showing a timeline for traced kernel events, and you can zoom in and filter at will. It works on the latest kernels, and it requires some new things/fixes in GTK. I don't recall exactly what version of GTK though. Dominique Toupin from Ericsson presented something about user requirements for tracing. Mostly though about who's who in the embedded world, and eclipse. Masami and Mathieu presented an update on their work. See their slides. The interesting thing to me was of course the new version of uprobes w/o underlying utrace presented by Jim Keniston. At the end of the session we had a discussion about the future of utrace. Roland wasn't there, butTom Tromey (also from RedHat) collected the feedback. Basically we are at a standstill now that utrace has been rejected yet again. There wasn't much advise that anybody could give, except jokingly, we decided that the only way in is to make it a part of perf events. There needs to be another refactoring, but most of all, this "killer app" that would be enabled because of utrace hasn't materialized yet. We think that having a good debugging story on Linux is enough of a killer app, for instance allowing multiple tracers, and not relying on SIGCHLD etc. I think this wasn't completely clear to the kernel community. Trying to achieve debugging via a gdb stub inside the kernel interfacing to utrace and that is controlled via the gdb remote protocol also lost its appeal (thankfully, since the gdb remote protocol is archaic). Somebody would have to be creative in how to submit utrace. It doesn't have to be called utrace (it was really a random choice, for lack of a letter that was not already used in front of the word "trace"). So basically, I think the ideas behind utrace are sound, and the necessity of a new interface is acknowledged. But I believe the integration/submission process with the kernel folks has to restart from scratch, clean slate. We'll see. There are many conferences and meetings coming up in the near future where things can be discussed further. On the second day, Friday, we had the tools talks. It was interesting to observe the more "kernel" oriented people's behavior towards the gcc etc community. The first talk was by Mark Mitchell, about Gcc and its new plugin architecture. After that, Paolo talked about the new C++1x standard, which will be finalized in 2011. Many features are already implemented in the libstdc++ library and gcc and usable today. We had a few minutes (really, the half day track was quite short) where Bradley Kuhn from the Software Freedom Law Center explained the GPLv3 exception for gcc (due to the new gcc plugin architecture and the availability of the intermediate results from the compilation, which is a new thing). I will not try to explain, but basically you cannot take the result of the preprocessing and then use that in your own proprietary compiler. After, we had a talk by Ian Taylor about the new Gold linker. One good thing in that area is that they are trying to make gold the new default linker (for instance Fedora will use gold as the distro linker). However gold is very different from binutils' old linker. It doesn't use a linker script, for instance. The kernel has been linked with gold many times as an exercise (the ground work was done by Kris Van Hees), but this needs to be constantly tested/monitored because the kernel linker script is very complex, and uses esoteric features (Wenji is now monitoring that each kernel RC can be built with gold). It was positive that people are now aware of gold and the need for it to be ported to more architectures. It seems that the porting is very easy, with little arch dependent code. Finally Tom Tromey presented about gdb and the archer project. Archer is a development branch of gdb mostly done by RedHat, where they are focusing on better c++ printing, c++ expression parsing, and plugins. The archer work is merged regularly in the gdb mainline. In general it was a good conference. I did miss most of the first day, because that's when I flew in. But I caught a couple of talks. Nothing earth shattering, except for Google giving each person registered a free Android phone. Yey.

  • Book Review: Oracle ADF Real World Developer’s Guide

    - by Frank Nimphius
    Recently PACKT Publishing published "Oracle ADF Real World Developer’s Guide" by Jobinesh Purushothaman, a product manager in our team. Though already the sixth book dedicated to Oracle ADF, it has a lot of great information in it that none of the previous books covered, making it a safe buy even for those who own the other books published by Oracle Press (McGrwHill) and PACKT Publishing. More than the half of the "Oracle ADF Real World Developer’s Guide" book is dedicated to Oracle ADF Business Components in a depth and clarity that allows you to feel the expertise that Jobinesh gained in this area. If you enjoy Jobinesh blog (http://jobinesh.blogspot.co.uk/) about Oracle ADF, then, no matter what expert you are in Oracle ADF, this book makes you happy as it provides you with detail information you always wished to have. If you are new to Oracle ADF, then this book alone doesn't get you flying, but, if you have some Java background, accelerates your learning big, big, big times. Chapter 1 is an introduction to Oracle ADF and not only explains the layers but also how it compares to plain Java EE solutions (page 13). If you are new to Oracle JDeveloper and ADF, then at the end of this chapter you know how to start JDeveloper and begin your ADF development Chapter 2 starts with what Jobinesh really is good at: ADF Business Components. In this chapter you learn about the architecture ingredients of ADF Business Components: View Objects, View Links, Associations, Entities, Row Sets, Query Collections and Application Modules. This chapter also provides a introduction to ADFBC SDO services, as well as sequence diagrams for what happens when you execute queries or commit updates. Chapter 3 is dedicated to entity objects and  is one of many chapters in this book you will enjoy and never want to miss. Jobinesh explains the artifacts that make up an entity object, how to work with entities and resource bundles, and many advanced topics, including inheritance, change history tracking, custom properties, validation and cursor handling.  Chapter 4 - you guessed it - is all about View objects. Comparable to entities, you learn about the XM files and classes that make a view object, as well as how to define and work with queries. List-of-values, inheritance, polymorphism, bind variables and data filtering are interesting - and important topics that follow. Again the chapter provides helpful sequence diagrams for you to understand what happens internally within a view object. Chapter 5 focuses on advanced view object and entity object topics, like lifecycle callback methods and when you want to override them. This chapter is a good digest of Jobinesh's blog entries (which most ADF developers have in their bookmark list). Really worth reading ! Chapter 6 then is bout Application Modules. Beside of what application modules are, this chapter covers important topics like properties, passivation, activation, application module pooling, how and where to write custom logic. In addition you learn about the AM lifecycle and request sequence. Chapter 7 is about the ADF binding layer. If you are new to Oracle ADF and got lost in the more advanced ADF Business Components chapters, then this chapter is where you get back into the game. In very easy terms, Jobinesh explains what the ADF binding is, how it fits into the JSF request lifecycle and what are the metadata file involved. Chapter 8 then goes into building data bound web user interfaces. In this chapter you get the basics of JavaServer Faces (e.g. managed beans) and learn about the interaction between the JSF UI and the ADF binding layer. Later this chapter provides advanced solutions for working with tree components and list of values. Chapter 9 introduces bounded task flows and ADF controller. This is a chapter you want to read if you are new to ADF of have started. Experts don't find anything new here, which doesn't mean that it is not worth reading it (I for example, enjoyed the controller talk very much) Chapter 10 is an advanced coverage of bounded task flow and talks about contextual events  Chapter 11 is another highlight and explains error handling, trains, transactions and more. I can only recommend you read this chapter. I am aware of many documents that cover exception handling in Oracle ADF (and my Oracle Magazine article for January/February 2013 does the same), but none that covers it in such a great depth. Chapter 12 covers ADF best practices, which is a great round-up of all the tips provided in this book (without Jobinesh to repeat himself). Its all cool stuff that helps you with your ADF projects. In summary, "Oracle ADF Real World Developer’s Guide" by Jobinesh Purushothaman is a great book and addition for all Oracle ADF developers and those who want to become one. Frank

  • ASP.NET, HTTP 404 and SEO

    - by paxer
    The other day our SEO Manager told me that he is not happy about the way ASP.NET application return HTTP response codes for Page Not Found (404) situation. I've started research and found interesting things, which could probably help others in similar situation.  1) By default ASP.NET application handle 404 error by using next web.config settings           <customErrors defaultRedirect="GenericError.htm" mode="On">             <error statusCode="404" redirect="404.html"/>           </customErrors> However this approach has a problem, and this is actually what our SEO manager was talking about. This is what HTTP return to request in case of Page not Found situation. So first of all it return HTTP 302 Redirect code and then HTTP 200 - ok code. The problem : We need to have HTTP 404 response code at the end of response for SEO purposes.  Solution 1 Let's change a bit our web.config settings to handle 404 error not on static html page but on .aspx page      <customErrors defaultRedirect="GenericError.htm" mode="On">             <error statusCode="404" redirect="404.aspx"/>           </customErrors> And now let's add in Page_Load event on 404.aspx page next lines     protected void Page_Load(object sender, EventArgs e)             {                 Response.StatusCode = 404;             } Now let's run our test again Now it has got better, last HTTP response code is 404, but my SEO manager still was not happy, becouse we still have 302 code before it, and as he said this is bad for Google search optimization. So we need to have only 404 HTTP code alone. Solution 2 Let's comment our web.config settings     <!--<customErrors defaultRedirect="GenericError.htm" mode="On">             <error statusCode="404" redirect="404.html"/>           </customErrors>--> Now, let's open our Global.asax file, or if it does not exist in your project - add it. Then we need to add next logic which will detect if server error code is 404 (Page not found) then handle it.       protected void Application_Error(object sender, EventArgs e)             {                            Exception ex = Server.GetLastError();                 if (ex is HttpException)                 {                     if (((HttpException)(ex)).GetHttpCode() == 404)                         Server.Transfer("~/404.html");                 }                 // Code that runs when an unhandled error occurs                 Server.Transfer("~/GenericError.htm");                  } Cool, now let's start our test again... Yehaa, looks like now we have only 404 HTTP response code, SEO manager and Google are happy and so do i:) Hope this helps!

  • XNA Notes 004

    - by George Clingerman
    The XNA community has been crazy busy again. It always make me fee like such a slacker collecting all of these notes as I see the tremendous output from people all over the world and it’s incredible and humbling. There are some amazingly skilled people working with XNA. On another not, I’m going to take a minute to get on my soapbox and say, if you are developing ANYTHING and are not using some sort of source/revision control, START IMMEDIATELY. This applies to teams of one. Projects for fun. And “I back up my hard drive” or “I use dropbox!” does NOT count as using source control. You’ll be doing yourself a HUGE favor if you find one, learn to use it and integrate it into your everyday workflow. I personally use Subversion. It’s hosted offsite at xp.dev.com and I use TortoiseSVN as my front end to interface with the repository. It’s simple and easy to use and has saved me from myself so many time. Honestly, get setup with some type of source control immediately. If you don’t understand how, grab another developer that does and have them walk you through setup and the basics of using it. Ok, I’m done.

  • Upgrading VSIX extensions from VS2012 to VS2013

    - by Tarun Arora [Microsoft MVP]
    Originally posted on: http://geekswithblogs.net/TarunArora/archive/2013/06/27/upgrading-vsix-extensions-from-vs2012-to-vs2013.aspx  As consumers of your Visual Studio extensions start to move over to VS 2013, you will have to upgrade the Visual Studio extensions you build for Visual Studio 2012 to Visual Studio 2013 and republish to the Visual Studio extension gallery. Failing which, it will not be possible for your consumers to install and use your extensions on Visual Studio 2013.   Objective In this blog post, I’ll show you how simple it is to upgrade your Visual Studio 2012 extension to Visual Studio 2013. There aren’t any reported breaking changes between VS 2012 SDK and VS 2013 SDK, the upgrade usually involves, rebuilding the extension against VS 2013 SDK and updating the vsix manifest file.              Walkthrough Download the Visual Studio 2013 SDK - You will need to download the Visual Studio 2013 SDK in order to open up the Visual Studio extension project in Visual Studio 2013. The SDK can be downloaded from here. Install the SDK before you proceed.                2. Once the VS 2013 SDK has been installed, open up your package project. For the purposes of this blog post, I’ll open up the Avanade Extension – Software Inventory in Visual Studio 2013. You will notice that Visual Studio doesn’t load the project but let’s you know that the project needs to be Migrated.                  3. Right click the project and choose the option ‘Reload Project’ from the Context Menu.                  4. Choosing the Reload Project option brings up an upgrade window, telling you that the upgrade is a one way only upgrade i.e. the project will be changed to work with Visual Studio 2013 and you will not be able to open the project up in Visual Studio 2012. My recommendation would be to create a Visual Studio 2013 branch and upgrading the project in that branch only, so if you need to go back to Visual Studio 2012 project at some point, you have a handy reference in a separate branch.             5. Upon clicking Ok, the project is updated. See below, the following changes are made at the time of upgrade,           - The runtime version is updated in the Resources.Designer.cs file                      - The Minimum version of Visual Studio in the package project file is changed from 11.0 to 12.0                    6. Reference VS 2013 dll’s rather than VS 2012 dll’s. So reference Microsoft.TeamFoundation.Client.dll and Microsoft.TeamFoundation.Controls.dll from C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\ReferenceAssemblies\v2.0 and C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\ReferenceAssemblies\v4.5. If you have any other API references, then change the references to point to VS 2013 instead of VS 2012.                          7. Rebuild your solution to ensure there are no breaking changes. Success!                8. Update VSIX Manifest file (the file source.extnsion.vsixmanifest contains the meta data for your VSIX).          - Update the Install Targets from 11.0 to 12.0. This basically enforces that the extension can be installed on Visual Studio 2013 version of Visual Studio.                         - Update the Dependencies from Visual Studio MPF 11.0 to Visual Studio MPF 12.0              9. Rebuild the solution and open up the bin folder for the Package project and look for the file *.vsix file [Microsoft Visual Studio Extension].         - This is basically the installer for your extension.                 - Double click the installer to launch the installer wizard. Viola! You can see the package installation wizard opens up and gives you the option to install the extension for Visual Studio 2013.                    - Click Install to Continue                    - Note – If you run into the exception “23/06/2013 10:42:18 - Install Error : Microsoft.VisualStudio.ExtensionManager.InstallByMsiException: The InstalledByMSI element in extension Avanade Extensions cannot be 'true' when installing an extension through the Extensions and Updates Installer.  The element can only be 'true' when an MSI lays down the extension manifest file.” Ensure you have the option “This VSIX is installed by Windows Installer” unchecked in the Install Targets tab.        10. Verifying that the extension has installed correctly.           - Open Extension Manager and verify that the installed extension shows up in the extension manager “list of installed VSIX”.                      11. First Look at the updated Extension                         - The links have now been moved to the context menu, so to see the navigation links, you’ll have to right click on the icon and select the option from the context menu.                                        Note – The Avanade Extension being used in the demo has been developed by Utkarsh and Tarun. The Software Inventory Extension for Visual Studio 2012…  allows you to see the list of Software installed on the hosted build server right from with in Visual Studio,  the extension also allows you to export this list to excel. More details on how this has been implemented can be found here.   I hope you found this useful. In case you have any questions or feedback, feel free to reach out on Visual Studio extensibility MSDN forums or via Microsoft Visual Studio feedback forum. Thank you for taking the time out and reading this blog post. If you enjoyed the post, remember to subscribe to http://feeds.feedburner.com/TarunArora. Stay tuned!

  • ASP.NET Web API - Screencast series Part 3: Delete and Update

    - by Jon Galloway
    We're continuing a six part series on ASP.NET Web API that accompanies the getting started screencast series. This is an introductory screencast series that walks through from File / New Project to some more advanced scenarios like Custom Validation and Authorization. The screencast videos are all short (3-5 minutes) and the sample code for the series is both available for download and browsable online. I did the screencasts, but the samples were written by the ASP.NET Web API team. In Part 1 we looked at what ASP.NET Web API is, why you'd care, did the File / New Project thing, and did some basic HTTP testing using browser F12 developer tools. In Part 2 we started to build up a sample that returns data from a repository in JSON format via GET methods. In Part 3, we'll start to modify data on the server using DELETE and POST methods. So far we've been looking at GET requests, and the difference between standard browsing in a web browser and navigating an HTTP API isn't quite as clear. Delete is where the difference becomes more obvious. With a "traditional" web page, to delete something'd probably have a form that POSTs a request back to a controller that needs to know that it's really supposed to be deleting something even though POST was really designed to create things, so it does the work and then returns some HTML back to the client that says whether or not the delete succeeded. There's a good amount of plumbing involved in communicating between client and server. That gets a lot easier when we just work with the standard HTTP DELETE verb. Here's how the server side code works: public Comment DeleteComment(int id) { Comment comment; if (!repository.TryGet(id, out comment)) throw new HttpResponseException(HttpStatusCode.NotFound); repository.Delete(id); return comment; } If you look back at the GET /api/comments code in Part 2, you'll see that they start the exact same because the use cases are kind of similar - we're looking up an item by id and either displaying it or deleting it. So the only difference is that this method deletes the comment once it finds it. We don't need to do anything special to handle cases where the id isn't found, as the same HTTP 404 handling works fine here, too. Pretty much all "traditional" browsing uses just two HTTP verbs: GET and POST, so you might not be all that used to DELETE requests and think they're hard. Not so! Here's the jQuery method that calls the /api/comments with the DELETE verb: $(function() { $("a.delete").live('click', function () { var id = $(this).data('comment-id'); $.ajax({ url: "/api/comments/" + id, type: 'DELETE', cache: false, statusCode: { 200: function(data) { viewModel.comments.remove( function(comment) { return comment.ID == data.ID; } ); } } }); return false; }); }); So in order to use the DELETE verb instead of GET, we're just using $.ajax() and setting the type to DELETE. Not hard. But what's that statusCode business? Well, an HTTP status code of 200 is an OK response. Unless our Web API method sets another status (such as by throwing the Not Found exception we saw earlier), the default response status code is HTTP 200 - OK. That makes the jQuery code pretty simple - it calls the Delete action, and if it gets back an HTTP 200, the server-side delete was successful so the comment can be deleted. Adding a new comment uses the POST verb. It starts out looking like an MVC controller action, using model binding to get the new comment from JSON data into a c# model object to add to repository, but there are some interesting differences. public HttpResponseMessage<Comment> PostComment(Comment comment) { comment = repository.Add(comment); var response = new HttpResponseMessage<Comment>(comment, HttpStatusCode.Created); response.Headers.Location = new Uri(Request.RequestUri, "/api/comments/" + comment.ID.ToString()); return response; } First off, the POST method is returning an HttpResponseMessage<Comment>. In the GET methods earlier, we were just returning a JSON payload with an HTTP 200 OK, so we could just return the  model object and Web API would wrap it up in an HttpResponseMessage with that HTTP 200 for us (much as ASP.NET MVC controller actions can return strings, and they'll be automatically wrapped in a ContentResult). When we're creating a new comment, though, we want to follow standard REST practices and return the URL that points to the newly created comment in the Location header, and we can do that by explicitly creating that HttpResposeMessage and then setting the header information. And here's a key point - by using HTTP standard status codes and headers, our response payload doesn't need to explain any context - the client can see from the status code that the POST succeeded, the location header tells it where to get it, and all it needs in the JSON payload is the actual content. Note: This is a simplified sample. Among other things, you'll need to consider security and authorization in your Web API's, and especially in methods that allow creating or deleting data. We'll look at authorization in Part 6. As for security, you'll want to consider things like mass assignment if binding directly to model objects, etc. In Part 4, we'll extend on our simple querying methods form Part 2, adding in support for paging and querying.

  • My History with Agile

    - by Robert May
    I’m going to write my history with Agile here.  That way, in future posts, I can refer back to it, instead of typing it out in the post that contains information you may actually want to read.  Note that I’m actually a pretty senior developer, and do lots of technical interviews.  I’m an Agile fan because of the difference it makes in peoples lives and the improvement in quality it brings, and I’ll sacrifice my technological advance to help teams. Management History I started management pretty early in my career, starting with the first job that I ever had.  I actually do NOT have a CS or similar degree.  I have a Bachelor’s of Business Administration with an emphasis in Computer Information Systems. My first management gigs were around call center work and were very schedule oriented.  I didn’t understand the true value of teams, and I’m ashamed to admit, I actually installed a fingerprint scanner as a time clock in this job.  I shudder to think of the impact that I had on the team spirit.  I didn’t even trust them enough to fill out their time cards correctly.  How sad. I was managing nearly 100 people in this position, with the help of a great set of subordinates. I did try to come up with reward programs for the team, but again, didn’t understand the concept of team, so instead of letting the team determine how the rewards should work, I mandated from on high, which isn’t a good thing. I was told that I wasn’t the type that would be a good manager by people whom I respected a lot.  They said it because I was a computer geek, since they don’t understand good management either, but in retrospect, they were right about me then.  I was too green. After my first job, I went on to other jobs and with the exception of one job, I’ve managed people at them all.  The rest of the management story is important for understanding agile, so I’ll save it for my next post. Technical History I’ve been in software development for many, many years.  I technically started programming on a commodore 64 in basic.  I didn’t know that I was programming, but I was sure having fun.  That was followed by batch files, Gorilla hacking (I always had to win), WordPerfect Macro programming and other things that taught me the basics. My first “real” job was with a telephone company, and that’s where I made my first database application in DataEase, wrote my first VBA app and started using real programming tools, like turbo pascal, vb3-vb5, and semi-real tools like RPG and VisualRPG.  I wrote my first web page in 1994, and built my first data driven web page in 1995 using perlDB.  You really can do anything with Perl.  At this time, I also started a Linux based internet service provider that is still in operation today.  One of the people I worked with is now a Microsoft employee building and designing frameworks you probably know well.  Smart guy.  I also built my first ASP applications connecting to Sql Server 6.5, setup Exchange 5.5 for the company, and many other system administration stuff.  I’m a programmer by choice, mostly because I don’t really like PC support. From there, I went on to a large state agency.  I got to see and maintain true waterfall projects.  5 years of maintaining the 200 VB COM+ (MTS, actually) dlls that were used to calculate a single number is a long time.  That was all Microsoft DNS technologies.  SQL Server and VB6 were the tools of choice, although .net started to be a factor near the end of employment.  I did some heavy XML work at this job and even wrote an XSD parser and validator in VB6 that was a shim until MSXML 3.0 came out.  Prior to 3.0, XSD’s weren’t supported, and I didn’t want to write DTDs. Ironically, jobs after this were more generic.  I pretty much settled in on the .net framework and revisions of it.  Lots of WPF, some silverlight, lots of ASP.NET, some SQL Azure, lots of SQL Server, some Oracle, but I don’t think that I was as passionate about development and technologies.  I was more into the management of development.  I like people.
