  • Adding custom filter in spring framework problem?

    - by user298768
    hello there iam trying to make a custom AuthenticationProcessingFilter to save some user data in the session after successful login here's my filter: Code: package projects.internal; import java.io.IOException; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.security.Authentication; import org.springframework.security.ui.webapp.AuthenticationProcessingFilter; public class MyAuthenticationProcessingFilter extends AuthenticationProcessingFilter { protected void onSuccessfulAuthentication(HttpServletRequest request, HttpServletResponse response, Authentication authResult) throws IOException { super.onSuccessfulAuthentication(request, response, authResult); request.getSession().setAttribute("myValue", "My value is set"); } } and here's my security.xml file Code: <beans:beans xmlns="http://www.springframework.org/schema/security" xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.xsd"> <global-method-security pre-post-annotations="enabled"> </global-method-security> <http use-expressions="true" auto-config="false" entry-point-ref="authenticationProcessingFilterEntryPoint"> <intercept-url pattern="/" access="permitAll" /> <intercept-url pattern="/images/**" filters="none" /> <intercept-url pattern="/scripts/**" filters="none" /> <intercept-url pattern="/styles/**" filters="none" /> <intercept-url pattern="/p/login.jsp" filters="none" /> <intercept-url pattern="/p/register" filters="none" /> <intercept-url pattern="/p/**" access="isAuthenticated()" /> <form-login login-processing-url="/j_spring_security_check" login-page="/p/login.jsp" authentication-failure-url="/p/login_error.jsp" /> <logout /> </http> <authentication-manager alias="authenticationManager"> <authentication-provider> <jdbc-user-service data-source-ref="dataSource"/> </authentication-provider> </authentication-manager> <beans:bean id="authenticationProcessingFilter" class="projects.internal.MyAuthenticationProcessingFilter"> <custom-filter position="AUTHENTICATION_PROCESSING_FILTER" /> </beans:bean> <beans:bean id="authenticationProcessingFilterEntryPoint" class="org.springframework.security.ui.webapp.AuthenticationProcessingFilterEntryPoint"> </beans:bean> </beans:beans> it gives an error here: Code: <custom-filter position="AUTHENTICATION_PROCESSING_FILTER" /> multiple annotation found at this line:cvc-attribute.3 cvc-complex-type.4 cvc-enumeration-vaild what is the problem? thanks in advance

  • Unique element ID, even if element doesn't have one

    - by Robert J. Walker
    I'm writing a GreaseMonkey script where I'm iterating through a bunch of elements. For each element, I need a string ID that I can use to reference that element later. The element itself doesn't have an id attribute, and I can't modify the original document to give it one (although I can make DOM changes in my script). I can't store the references in my script because when I need them, the GreaseMonkey script itself will have gone out of scope. Is there some way to get at an "internal" ID that the browser uses, for example? A Firefox-only solution is fine; a cross-browser solution that could be applied in other scenarios would be awesome. Edit: If the GreaseMonkey script is out of scope, how are you referencing the elements later? They GreaseMonkey script is adding events to DOM objects. I can't store the references in an array or some other similar mechanism because when the event fires, the array will be gone because the GreaseMonkey script will have gone out of scope. So the event needs some way to know about the element reference that the script had when the event was attached. And the element in question is not the one to which it is attached. Can't you just use a custom property on the element? Yes, but the problem is on the lookup. I'd have to resort to iterating through all the elements looking for the one that has that custom property set to the desired id. That would work, sure, but in large documents it could be very time consuming. I'm looking for something where the browser can do the lookup grunt work. Wait, can you or can you not modify the document? I can't modify the source document, but I can make DOM changes in the script. I'll clarify in the question. Can you not use closures? Closuses did turn out to work, although I initially thought they wouldn't. See my later post. It sounds like the answer to the question: "Is there some internal browser ID I could use?" is "No."

  • c#: Clean way to fit a collection into a multidimensional array?

    - by Rosarch
    I have an ICollection<MapNode>. Each MapNode has a Position attribute, which is a Point. I want to sort these points first by Y value, then by X value, and put them in a multidimensional array (MapNode[,]). The collection would look something like this: (30, 20) (20, 20) (20, 30) (30, 10) (30, 30) (20, 10) And the final product: (20, 10) (20, 20) (20, 30) (30, 10) (30, 20) (30, 30) Here is the code I have come up with to do it. Is this hideously unreadable? I feel like it's more hacky than it needs to be. private Map createWorldPathNodes() { ICollection<MapNode> points = new HashSet<MapNode>(); Rectangle worldBounds = WorldQueryUtils.WorldBounds(); for (float x = worldBounds.Left; x < worldBounds.Right; x += PATH_NODE_CHUNK_SIZE) { for (float y = worldBounds.Y; y > worldBounds.Height; y -= PATH_NODE_CHUNK_SIZE) { // default is that everywhere is navigable; // a different function is responsible for determining the real value points.Add(new MapNode(true, new Point((int)x, (int)y))); } } int distinctXValues = points.Select(node => node.Position.X).Distinct().Count(); int distinctYValues = points.Select(node => node.Position.Y).Distinct().Count(); IList<MapNode[]> mapNodeRowsToAdd = new List<MapNode[]>(); while (points.Count > 0) // every iteration will take a row out of points { // get all the nodes with the greatest Y value currently in the collection int currentMaxY = points.Select(node => node.Position.Y).Max(); ICollection<MapNode> ythRow = points.Where(node => node.Position.Y == currentMaxY).ToList(); // remove these nodes from the pool we're picking from points = points.Where(node => ! ythRow.Contains(node)).ToList(); // ToList() is just so it is still a collection // put the nodes with max y value in the array, sorting by X value mapNodeRowsToAdd.Add(ythRow.OrderByDescending(node => node.Position.X).ToArray()); } MapNode[,] mapNodes = new MapNode[distinctXValues, distinctYValues]; int xValuesAdded = 0; int yValuesAdded = 0; foreach (MapNode[] mapNodeRow in mapNodeRowsToAdd) { xValuesAdded = 0; foreach (MapNode node in mapNodeRow) { // [y, x] may seem backwards, but mapNodes[y] == the yth row mapNodes[yValuesAdded, xValuesAdded] = node; xValuesAdded++; } yValuesAdded++; } return pathNodes; } The above function seems to work pretty well, but it hasn't been subjected to bulletproof testing yet.

  • Adding objects to an NSMutableArray, order seems odd when parsing from an XML file

    - by diatrevolo
    Hello: I am parsing an XML file for two elements: "title" and "noType". Once these are parsed, I am adding them to an object called aMaster, an instance of my own Master class that contains NSString variables. I am then adding these instances to an NSMutableArray on a singleton, in order to call them elsewhere in the program. The problem is that when I call them, they don't seem to be on the same NSMutableArray index... each index contains either the title OR the noType element, when it should be both... can anyone see what I may be doing wrong? Below is the code for the parser. Thanks so much!! #import "XMLParser.h" #import "Values.h" #import "Listing.h" #import "Master.h" @implementation XMLParser @synthesize sharedSingleton, aMaster; - (XMLParser *) initXMLParser { [super init]; sharedSingleton = [Values sharedValues]; aMaster = [[Master init] alloc]; return self; } - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict { aMaster = [[Master alloc] init]; //Extract the attribute here. if ([elementName isEqualToString:@"intro"]) { aMaster.intro = [attributeDict objectForKey:@"enabled"]; } else if ([elementName isEqualToString:@"item"]) { aMaster.item_type = [attributeDict objectForKey:@"type"]; //NSLog(@"Did find item with type %@", [attributeDict objectForKey:@"type"]); //NSLog(@"Reading id value :%@", aMaster.item_type); } else { //NSLog(@"No known elements"); } //NSLog(@"Processing Element: %@", elementName); //HERE } - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { if(!currentElementValue) currentElementValue = [[NSMutableString alloc] initWithString:string]; else { [currentElementValue appendString:string];//[tempString stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]]; CFStringTrimWhitespace((CFMutableStringRef)currentElementValue); } } - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if ([elementName isEqualToString:@"item"]) { [sharedSingleton.master addObject:aMaster]; NSLog(@"Added %@ and %@ to the shared singleton", aMaster.title, aMaster.noType); //Only having one at a time added... don't know why [aMaster release]; aMaster = nil; } else if ([elementName isEqualToString:@"title"]) { [aMaster setValue:currentElementValue forKey:@"title"]; } else if ([elementName isEqualToString:@"noType"]) { [aMaster setValue:currentElementValue forKey:@"noType"]; //NSLog(@"%@ should load into the singleton", aMaster.noType); } NSLog(@"delimiter"); NSLog(@"%@ should load into the singleton", aMaster.title); NSLog(@"%@ should load into the singleton", aMaster.noType); [currentElementValue release]; currentElementValue = nil; } - (void) dealloc { [aMaster release]; [currentElementValue release]; [super dealloc]; } @end

  • Problems with contenteditable in Firefox

    - by Jonathan
    Hello, I am working on a Javascript WYSIWYG editor in Firefox. I am using a div with the contenteditable attribute set to true in order to accomplish this (I cannot use a contenteditable iframe for this particular project). This contenteditable div is nested in another div that is not contenteditable. I am encountering the following two problems when using execCommand to apply formatting, including font style and size, as well as bold, italic, and underline: When all text in the div is selected, execCommand simply does not work. execCommand works fine when only part of the text is selected, but does nothing when all of the text is selected. Applying formatting with no text selected yields unexpected results. For example, when calling execCommand('bold') with no text selected and then typing results in bold text being typed until a spacebar is inserted, at which point the bold formatting is lost (until another space is inserted, interestingly enough; then the text becomes bold again). To see what I mean, please try running the following HTML code in Firefox 3: <html> <head><title></title></head> <body> <button onClick="execCommand('bold', false, null);">Bold</button> <div style="width: 300px; border: 1px solid #000000;"> <div contenteditable="true">Some editable text</div> </div> </body> </html> Please try the following: Select the word "Some" only. Click the Bold button. This will make the text bold, as expected. Select the entire phrase "Some editable text" (either manually or using CTRL-A). Click the Bold button. Nothing happens. This demonstrates the first bug shown above. Hit the backspace key to clear the div. Click the Bold button and begin typing. Type a few words with spaces. This will demonstrate the second bug. Any ideas on what could be causing these problems and how to work around them would be greatly appreciated!

  • Visual Studio soft-crashing when encountering XAML Errors in initialize.

    - by Aren
    I've been having some serious issues with Visual Studio 2010 as of late. It's been crashing in a peculiar way when I encounter certain types of XAML errors during the InitializeComponent() of a control/window. The program breaks and visual studio gears up like it's catching an exception (because it is) and then stops midway displaying a broken highlight in my XAML file with no details as to what is wrong. Example: There is not pop outs, or details Anywhere about what is wrong, only a callstack that points to my InitializeComponent() call. Now normally I'd just do some trial and error to fix this problem, and find out where i messed up, but the real problem isn't my code. Visual Studio is rendered completely useless at this point. It reports my application still in "Running" mode. The Stop/Break/Restart buttons on the toolbar or in the menus don't do anything (but grey out). Closing the application does not stop this behaviour, closing visual studio gets it stuck in a massive loop where it yells at me complaining every file open is not in the debug project, then repeats this process when i have exausted every open file. I have to force-close devenv.exe, and after this happening 3-4 times in a row it's a lot of wasted time (as my projects are usually pretty big and studio can be quite slow @ loading). To the point Has anyone else experienced this? How can I stop studio from locking up. Can I at LEAST get information out of this beast another way so i can fix my XAML error sooner rather than after 3-4 trial-and-error compiles yielding the same crash? Any & All help would be appreciated. Visual Studio 2010 version: 10.0.30319.1RTM Edit & Update FWIW, mostly the errors that cause this are XamlParseExceptions (I figured this out after i found what was wrong with my XAML). I think I need to be clearer though, Im not looking for the solution to my code problem, as these are usually typos / small things, I'm looking for a solution to VStudio getting all buggered up as a result. The particular error in the above image that 100% for sure caused this was a XamlParseException caused by forgetting a Value attribute on a data trigger. I've fixed that part but it still doesn't tell my why my studio becomes a lump of neutered program when a perfectly normal exception is thrown in the parsing of the XAML. Code that will cause this issue (at least for me) This is the base template WPF Application, with the following Window.xaml code. The problem is a missing Value="True" on the <DataTrigger ...> in the template. It generates a XamlParseException and Visual Studio Crashes as described above when debugging it. Final Notes The following solutions did not help me: Restarting Visual Studio Rebooting Reinstalling Visual Studio

  • No output from Linq to XML

    - by Gogster
    Hi all, I have the following code: protected void Page_Load(object sender, EventArgs e) { XElement xml = XElement.Load(Server.MapPath("ArenasMembers.xml")); var query = from p in xml.Descendants("members") select new { Name = p.Element("name").Value, Email = p.Attribute("email").Value }; foreach (var member in query) { Response.Write("Employee: " + member.Name + " " + member.Email + "<br />"); } } Which, using the hover information in Visual Studio, is reading the XNL file in correctly, however the foreach is not outputting any of the records. XML: <?xml version="1.0" encoding="utf-8" ?> <members> <member> <arena>EAA Office</arena> <memberid>1</memberid> <name>Jane Doe</name> <email>[email protected]</email> </member> <member> <arena>EAA Office</arena> <memberid>2</memberid> <name>John Bull</name> <email>[email protected]</email> </member> <member> <arena>O2 Arena</arena> <memberid>3</memberid> <name>John Doe</name> <email>[email protected]</email> </member> <member> <arena>O2 Arena</arena> <memberid>4</memberid> <name>Bernard Cribbins</name> <email>[email protected]</email> </member> <member> <arena>Colourline Arena</arena> <memberid>5</memberid> <name>John Bon Jovi</name> <email>[email protected]</email> </member> <member> <arena>NIA</arena> <memberid>6</memberid> <name>Rhianna</name> <email>[email protected]</email> </member> </members> Can you see what is wrong?

  • CLR 4.0 inlining policy? (maybe bug with MethodImplOptions.NoInlining)

    - by ControlFlow
    I've testing some new CLR 4.0 behavior in method inlining (cross-assembly inlining) and found some strage results: Assembly ClassLib.dll: using System.Diagnostics; using System; using System.Reflection; using System.Security; using System.Runtime.CompilerServices; namespace ClassLib { public static class A { static readonly MethodInfo GetExecuting = typeof(Assembly).GetMethod("GetExecutingAssembly"); public static Assembly Foo(out StackTrace stack) // 13 bytes { // explicit call to GetExecutingAssembly() stack = new StackTrace(); return Assembly.GetExecutingAssembly(); } public static Assembly Bar(out StackTrace stack) // 25 bytes { // reflection call to GetExecutingAssembly() stack = new StackTrace(); return (Assembly) GetExecuting.Invoke(null, null); } public static Assembly Baz(out StackTrace stack) // 9 bytes { stack = new StackTrace(); return null; } public static Assembly Bob(out StackTrace stack) // 13 bytes { // call of non-inlinable method! return SomeSecurityCriticalMethod(out stack); } [SecurityCritical, MethodImpl(MethodImplOptions.NoInlining)] static Assembly SomeSecurityCriticalMethod(out StackTrace stack) { stack = new StackTrace(); return Assembly.GetExecutingAssembly(); } } } Assembly ConsoleApp.exe using System; using ClassLib; using System.Diagnostics; class Program { static void Main() { Console.WriteLine("runtime: {0}", Environment.Version); StackTrace stack; Console.WriteLine("Foo: {0}\n{1}", A.Foo(out stack), stack); Console.WriteLine("Bar: {0}\n{1}", A.Bar(out stack), stack); Console.WriteLine("Baz: {0}\n{1}", A.Baz(out stack), stack); Console.WriteLine("Bob: {0}\n{1}", A.Bob(out stack), stack); } } Results: runtime: 4.0.30128.1 Foo: ClassLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null at ClassLib.A.Foo(StackTrace& stack) at Program.Main() Bar: ClassLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null at ClassLib.A.Bar(StackTrace& stack) at Program.Main() Baz: at Program.Main() Bob: ClassLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null at Program.Main() So questions are: Why JIT does not inlined Foo and Bar calls as Baz does? They are lower than 32 bytes of IL and are good candidates for inlining. Why JIT inlined call of Bob and inner call of SomeSecurityCriticalMethod that is marked with the [MethodImpl(MethodImplOptions.NoInlining)] attribute? Why GetExecutingAssembly returns a valid assembly when is called by inlined Baz and SomeSecurityCriticalMethod methods? I've expect that it performs the stack walk to detect the executing assembly, but stack will contains only Program.Main() call and no methods of ClassLib assenbly, to ConsoleApp should be returned.

  • Sockets, Threads and Services in android, how to make them work together ?

    - by Spredzy
    Hi all, I am facing a probleme with threads and sockets I cant figure it out, if someone can help me please i would really appreciate. There are the facts : I have a service class NetworkService, inside this class I have a Socket attribute. I would like it be at the state of connected for the whole lifecycle of the service. To connect the socket I do it in a thread, so if the server has to timeout, it would not block my UI thread. Problem is, into the thread where I connect my socket everything is fine, it is connected and I can talk to my server, once this thread is over and I try to reuse the socket, in another thread, I have the error message Socket is not connected. Questions are : - Is the socket automatically disconnected at the end of the thread? - Is their anyway we can pass back a value from a called thread to the caller ? Thanks a lot, Here is my code public class NetworkService extends Service { private Socket mSocket = new Socket(); private void _connectSocket(String addr, int port) { Runnable connect = new connectSocket(this.mSocket, addr, port); new Thread(connect).start(); } private void _authentification() { Runnable auth = new authentification(); new Thread(auth).start(); } private INetwork.Stub mBinder = new INetwork.Stub() { @Override public int doConnect(String addr, int port) throws RemoteException { _connectSocket(addr, port); _authentification(); return 0; } }; class connectSocket implements Runnable { String addrSocket; int portSocket; int TIMEOUT=5000; public connectSocket(String addr, int port) { addrSocket = addr; portSocket = port; } @Override public void run() { SocketAddress socketAddress = new InetSocketAddress(addrSocket, portSocket); try { mSocket.connect(socketAddress, TIMEOUT); PrintWriter out = new PrintWriter(mSocket.getOutputStream(), true); out.println("test42"); Log.i("connectSocket()", "Connection Succesful"); } catch (IOException e) { Log.e("connectSocket()", e.getMessage()); e.printStackTrace(); } } } class authentification implements Runnable { private String constructFirstConnectQuery() { String query = "toto"; return query; } @Override public void run() { BufferedReader in; PrintWriter out; String line = ""; try { in = new BufferedReader(new InputStreamReader(mSocket.getInputStream())); out = new PrintWriter(mSocket.getOutputStream(), true); out.println(constructFirstConnectQuery()); while (mSocket.isConnected()) { line = in.readLine(); Log.e("LINE", "[Current]- " + line); } } catch (IOException e) {e.printStackTrace();} } }

  • Rails: How do I unserialize from database?

    - by Macint
    Hello, I am currently trying to save information for an invoice/bill. On the invoice I want to show what the total price is made up of. The procedures & items, their price and the qty. So in the end I hope to get it to look like this: Consult [date] [total_price] Procedure_name [price] [qty] Procedure_name [price] [qty] Consult [date] [total_price] Procedure_name [price] [qty] etc... All this information is available through the database but i want to save the information as a separate copy. That way if the user changes the price of some procedures the invoice information is still correct. I thought i'd do this by serializing and save the data to a column (consult_data) in the Invoice table. My Model: class Invoice < ActiveRecord::Base ...stuff... serialize :consult_data ... end This is what I get from the form (1 consult and 3 procedures): {"commit"=>"Save draft", "authenticity_token"=>"MZ1OiOCtj/BOu73eVVkolZBWoN8Fy1skHqKgih7Sbzw=", "id"=>"113", "consults"=>[{"consult_date"=>"2010-02-20", "consult_problem"=>"ABC", "procedures"=>[{"name"=>"asdasdasd", "price"=>"2.0", "qty"=>"1"}, {"name"=>"AAAnd another one", "price"=>"45.0", "qty"=>"4"}, {"name"=>"asdasdasd", "price"=>"2.0", "qty"=>"1"}], "consult_id"=>"1"}]} My save action: def add_to_invoice @invoice = @current_practice.invoices.find_by_id(params[:id]) @invoice.consult_data=params[:consults] if @invoice.save render :text => "I think it worked" else render :text => "I don't think it worked'" end end It does save to the database and if I look at the entry in the console I can see that it is all there: consult_data: "--- \n- !map:HashWithIndifferentAccess \n consult_da..." (---The question---) But I can't seam to get back my data. I tried defining a variable to the consult_data attribute and then doing "variable.consult_problem" or "variable[:consult_problem]" (also tried looping) but it only throws no-method-errors back at me. How do I unserialize the data from the database and turn it back into hash that i can use? Thank you very much for any help!

    I have a xml file which I want to transform in a jsf code page.

Thanks! Update: Let me clarify what I want to do. I want to generate a jsf page dynamically depending on the attributes of a xml file, for instance, 2 input texts, 3 check boxes, etc. To make the transformation to jsf I thought in two approaches, one using jstl and another using xslt. The problem with the former is that I couldn't integrate jstl with jsf code (to set jsf components attributes using jstl variables) and with the last approach, I'm facing the problem described above.I wouldn't like to create components in java (UIComponents). Any suggestions?

  • Why Won't My ASP.NET Hyperlink Work in IE?

    - by Giffyguy
    I'm making a very simple ad button system using ASP.NET 2.0 The advertisment is a 150x150px square that is displayed on "the r house." (Scroll down a little and you'll see the bright green "Angry Octopus" on the right side of the screen.) Now, I am not the administrator of "the r house." Instead, I am the administrator of angryoctopus.net Therefore, I don't have the ability to change the ad display code on a whim. So I gave "the r house" this snippet of code to display our ad nicely, while still allowing me to customize the back-end code on my end: <iframe src="http://www.angryoctopus.net/Content/Ad/150x150.aspx" frameborder="0" width="150" height="150" scrolling="no" style="padding: 0; margin: 0;"></iframe> You'll find this snippet in the page source to "the r house." On my side, the code looks like this: <asp:HyperLink runat="server" NavigateUrl="http://www.angryoctopus.net/" Target="_top"> <asp:Panel ID="pnlMain" runat="server" BackColor="#D1E231" style="padding: 0; margin: 0" Width="150" Height="150"> <asp:Image runat="server" ImageUrl="http://www.angryoctopus.net/Content/Ad/150x150.png" BorderStyle="None" style="padding: 0; margin: 0" /> </asp:Panel> </asp:HyperLink> ... and there's some insignificant back-end C# code for hit-counting. This looks all well and good from the code standpoint, as far as I can tell. Everything works in Firefox and Chrome. Also, everything appears to work in IE8 in all of my tests. I haven't tested IE7. But when you view "the r house" in IE(8) the hyperlink doesn't do anything, and the cursor doesn't indicate that the hyperlink is even there. Although you can see the target URL in the status bar. I've considered the fact that "the r house" uses XHTML 1.0 Strict could be causing problems, but that would probably effect Firefox and Chrome right? (My aspx pages use XHTML 1.0 Transitional) My only other theory is that some random CSS class could be applying a weird attribute to my iframe, but again I would expect that would effect Firefox and Chrome. Is this a security issue with IE? Does anyone know what part of the r house's website could be blocking the hyperlink in IE? And how can I get around this without having to hard code anything on the r house's website? Is there an alternative to iframe that would do the same job without requiring complicated scripting?

  • Need help with auto-scaffolding template in ASP.NET MVC

    - by DanM
    I'm trying to write an auto-scaffolder for Index views. I'd like to be able to pass in a collection of models or view-models (e.g., IQueryable<MyViewModel>) and get back an HTML table that uses the DisplayName attribute for the headings (th elements) and Html.Display(propertyName) for the cells (td elements). Each row should correspond to one item in the collection. Here's what I have so far: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> <% var items = (IQueryable<TestProj.ViewModels.TestViewModel>)Model; // Should be generic! var properties = items.First().GetMetadata().Properties .Where(pm => pm.ShowForDisplay && !ViewData.TemplateInfo.Visited(pm)); %> <table> <tr> <% foreach(var property in properties) { %> <th> <%= property.DisplayName %> </th> <% } %> </tr> <% foreach(var item in items) { %> <tr> <% foreach(var property in properties) { %> <td> <%= Html.Display(property.DisplayName) %> // This doesn't work! </td> <% } %> </tr> <% } %> </table> Two problems with this: I'd like it to be generic. So, I'd like to replace var items = (IQueryable<TestProj.ViewModels.TestViewModel>)Model; with var items = (IQueryable<T>)Model; or something to that effect. The <td> elements are not working because the Html in <%= Html.Display(property.DisplayName) %> contains the model for the view, which is a collection of items, not the item itself. Somehow, I need to obtain an HtmlHelper object whose Model property is the current item, but I'm not sure how to do that. How do I solve these two problems?

  • JSON.Net: deserializing polymorphic types without specifying the assembly

    - by Frank Schwieterman
    I see that using JSON.Net, I can decode polymorphic objects if a $type attribute specifies the specific type of the JSON object. In all the examples I've seen, $type includes the namespace. Is it possible to make this work including just a simple typename without the assembly? I'd be happy to specify a default assembly to the JsonSerializer if thats possible I am able to deserialize the JSON using: public class SingleAssemblyJsonTypeBinder : SerializationBinder { private readonly Assembly _assembly; private Dictionary _typesBySimpleName = new Dictionary(StringComparer.OrdinalIgnoreCase); private Dictionary _simpleNameByType = new Dictionary(); public SingleAssemblyJsonTypeBinder(Assembly assembly) { _assembly = assembly; _typesBySimpleName = new Dictionary<string, Type>(); foreach (var type in _assembly.GetTypes().Where(t => t.IsPublic)) { if (_typesBySimpleName.ContainsKey(type.Name)) throw new InvalidOperationException("Cannot user PolymorphicBinder on a namespace where multiple public types have same name."); _typesBySimpleName[type.Name] = type; _simpleNameByType[type] = type.Name; } } public override Type BindToType(string assemblyName, string typeName) { Type result; if (_typesBySimpleName.TryGetValue(typeName.Trim(), out result)) return result; return null; } public override void BindToName(Type serializedType, out string assemblyName, out string typeName) { string name; if (_simpleNameByType.TryGetValue(serializedType, out name)) { typeName = name; assemblyName = null;// _assembly.FullName; } else { typeName = null; assemblyName = null; } } } ... public static JsonSerializerSettings GetJsonSerializationSettings() { var settings = new JsonSerializerSettings(); settings.Binder = new SingleAssemblyJsonTypeBinder(typeof(MvcApplication).Assembly); settings.TypeNameHandling = TypeNameHandling.Objects; return settings; } .... var serializer = JsonSerializer.Create(settings); I haven't been able to make this work with MVC though, I'm configuring json deserialization per the code below in Application_Start, and the object is deserialized, but using the base type one. GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.Binder = new SingleAssemblyJsonTypeBinder(this.GetType().Assembly); GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.TypeNameHandling = TypeNameHandling.All; GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.TypeNameAssemblyFormat = FormatterAssemblyStyle.Simple;

  • Animating a pulsing UILabel?

    - by fuzzygoat
    I am trying to animate the color the the text on a UILabel to pulse from: [Black] to [White] to [Black] and repeat. - (void)timerFlash:(NSTimer *)timer { [[self navTitle] setTextColor:[[UIColor whiteColor] colorWithAlphaComponent:0.0]]; [UIView animateWithDuration:1 delay:0 options:UIViewAnimationOptionAllowUserInteraction animations:^{[[self navTitle] setTextColor:[[UIColor whiteColor] colorWithAlphaComponent:1.0]];} completion:nil]; } . [self setFadeTimer:[NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(timerFlash:) userInfo:nil repeats:YES]]; Firstly I am not sure of my method, my plan (as you can see above) was to set up a animation block and call it using a repeating NSTimer until canceled. My second problem (as you can see above) is that I am animating from black (alpha 0) to white (alpha 1) but I don't know how to animate back to black again so the animation loops seamlessly Essentially what I want is the text color to pulse on a UILabel until the user presses a button to continue. EDIT_001: I was getting into trouble because you can't animate [UILabel setColor:] you can however animated [UILabel setAlpha:] so I am going to give that a go. EDIT_002: - (void)timerFlash:(NSTimer *)timer { [[self navTitle] setAlpha:0.5]; [UIView animateWithDuration:2 delay:0 options:UIViewAnimationOptionAllowUserInteraction animations:^{[[self navTitle] setAlpha:0.9];} completion:nil]; } This works (BTW: I do want it to stop which is why I hooked it up to a NSTimer so I can cancel that) the only thing is that this animates from midGray to nearWhite and then pops back. Does anyone know how I would animate back from nearWhite to midGray so I get a nice smooth cycle? EDIT_003: (Solution) The code suggested by dave DeLong (see below) does indeed work when modified to use the CALayer opacity style attribute: UILabel *navTitle; @property(nonatomic, retain) UILabel *navTitle; . // ADD ANIMATION CABasicAnimation *anim = [CABasicAnimation animationWithKeyPath:@"opacity"]; [anim setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]]; [anim setFromValue:[NSNumber numberWithFloat:0.5]]; [anim setToValue:[NSNumber numberWithFloat:1.0]]; [anim setAutoreverses:YES]; [anim setDuration:0.5]; [[[self navTitle] layer] addAnimation:anim forKey:@"flash"]; . // REMOVE ANIMATION [[[self navTitle] layer] removeAnimationForKey:@"flash__"];

  • How can I pass managed objects from one AppDomain to another?

    - by Dennis P
    I have two assemblies that I'm trying to link together. One is a sort of background process that's built with WinForms and will be designed to run as a Windows Service. I have a second project that will act as a UI for the background process whenever a user launches it. I've never tried attempting something like this with managed code before, so I've started trying to use windows messages to communicate between the two processes. I'm struggling when it comes to passing more than just IntPtrs back and forth, however. Here's the code from a control in my UI project that registers itself with the background process: public void Init() { IntPtr hwnd = IntPtr.Zero; Process[] ps = Process.GetProcessesByName("BGServiceApp"); Process mainProcess = null; if(ps == null || ps.GetLength(0) == 0) { mainProcess = LaunchApp(); } else { mainProcess = ps[0]; } SendMessage(mainProcess.MainWindowHandle, INIT_CONNECTION, this.Handle, IntPtr.Zero); } protected override void WndProc(ref Message m) { if(m.Msg == INIT_CONFIRMED && InitComplete != null) { string message = Marshal.PtrToStringAuto(m.WParam); Marshal.FreeHGlobal(m.WParam); InitComplete(message, EventArgs.Empty); } base.WndProc(ref m); } This is the code from the background process that's supposed to receive a request from the UI process to register for status updates and send a confirmation message. protected override void WndProc(ref Message m) { if(m.Msg == INIT_CONNECTION) { RegisterUIDispatcher(m.WParam); Respond(m.WParam); } if(m.Msg == UNINIT_CONNECTION) { UnregisterUIDispatcher(m.WParam); if(m_RegisteredDispatchers.Count == 0) { this.Close(); } } base.WndProc(ref m); } private void Respond(IntPtr caller) { string test = "Registration confirmed!"; IntPtr ptr = Marshal.StringToHGlobalAuto(test); SendMessage(caller, INIT_CONFIRMED, ptr, IntPtr.Zero); } } The UI process receives the INIT_CONFIRMED message from my background process, but when I try to marshal the IntPtr back into a string, I get an empty string. Is the area of heap I'm using out of scope to the other process or am I missing some security attribute maybe? Is there a better and cleaner way to go about something like this using an event driven model?

  • Crash in OS X Core Data Utility Tutorial

    - by vinogradov
    I'm trying to follow Apple's Core Data utility Tutorial. It was all going nicely, until... The tutorial uses a custom sub-class of NSManagedObject, called 'Run'. Run.h looks like this: #import <Foundation/Foundation.h> #import <CoreData/CoreData.h> @interface Run : NSManagedObject { NSInteger processID; } @property (retain) NSDate *date; @property (retain) NSDate *primitiveDate; @property NSInteger processID; @end Now, in Run.m we have an accessor method for the processID variable: - (void)setProcessID:(int)newProcessID { [self willChangeValueForKey:@"processID"]; processID = newProcessID; [self didChangeValueForKey:@"processID"]; } In main.m, we use functions to set up a managed object model and context, instantiate an entity called run, and add it to the context. We then get the current NSprocessInfo, in preparation for setting the processID of the run object. NSManagedObjectContext *moc = managedObjectContext(); NSEntityDescription *runEntity = [[mom entitiesByName] objectForKey:@"Run"]; Run *run = [[Run alloc] initWithEntity:runEntity insertIntoManagedObjectContext:moc]; NSProcessInfo *processInfo = [NSProcessInfo processInfo]; Next, we try to call the accessor method defined in Run.m to set the value of processID: [run setProcessID:[processInfo processIdentifier]]; And that's where it's crashing. The object run seems to exist (I can see it in the debugger), so I don't think I'm messaging nil; on the other hand, it doesn't look like the setProcessID: message is actually being received. I'm obviously still learning this stuff (that's what tutorials are for, right?), and I'm probably doing something really stupid. However, any help or suggestions would be gratefully received! ===MORE INFORMATION=== Following up on Jeremy's suggestions: The processID attribute in the model is set up like this: NSAttributeDescription *idAttribute = [[NSAttributeDescription alloc]init]; [idAttribute setName:@"processID"]; [idAttribute setAttributeType:NSInteger32AttributeType]; [idAttribute setOptional:NO]; [idAttribute setDefaultValue:[NSNumber numberWithInteger:-1]]; which seems a little odd; we are defining it as a scalar type, and then giving it an NSNumber object as its default value. In the associated class, Run, processID is defined as an NSInteger. Still, this should be OK - it's all copied directly from the tutorial. It seems to me that the problem is probably in there somewhere. By the way, the getter method for processID is defined like this: - (int)processID { [self willAccessValueForKey:@"processID"]; NSInteger pid = processID; [self didAccessValueForKey:@"processID"]; return pid; } and this method works fine; it accesses and unpacks the default int value of processID (-1). Thanks for the help so far!

  • Symfony2 Entity to array

    - by Adriano Pedro
    I'm trying to migrate my flat php project to Symfony2, but its coming to be very hard. For instance, I have a table of Products specification that have several specifications and are distinguishables by its "cat" attribute in that Extraspecs DB table. Therefore I've created a Entity for that table and want to make an array of just the specifications with "cat" = 0... I supose the code is this one.. right? $typeavailable = $this->getDoctrine() ->getRepository('LabsCatalogBundle:ProductExtraspecsSpecs') ->findBy(array('cat' => '0')); Now how can i put this in an array to work with a form like this?: form = $this ->createFormBuilder($product) ->add('specs', 'choice', array('choices' => $typeavailableArray), 'multiple' => true) Thank you in advance :) # Thank you all.. But now I've came across with another problem.. In fact i'm building a form from an existing object: $form = $this ->createFormBuilder($product) ->add('name', 'text') ->add('genspec', 'choice', array('choices' => array('0' => 'None', '1' => 'General', '2' => 'Specific'))) ->add('isReg', 'choice', array('choices' => array('0' => 'Material', '1' => 'Reagent', '2' => 'Antibody', '3' => 'Growth Factors', '4' => 'Rodents', '5' => 'Lagomorphs'))) So.. in that case my current value is named "extraspecs", so i've added this like: ->add('extraspecs', 'entity', array( 'label' => 'desc', 'empty_value' => ' --- ', 'class' => 'LabsCatalogBundle:ProductExtraspecsSpecs', 'property' => 'specsid', 'query_builder' => function(EntityRepository $er) { return $er ->createQueryBuilder('e'); But "extraspecs" come from a relationship of oneToMany where every product has several extraspecs... Here is the ORM: Labs\CatalogBundle\Entity\Product: type: entity table: orders__regmat id: id: type: integer generator: { strategy: AUTO } fields: name: type: string length: 100 catnumber: type: string scale: 100 brand: type: integer scale: 10 company: type: integer scale: 10 size: type: decimal scale: 10 units: type: integer scale: 10 price: type: decimal scale: 10 reqcert: type: integer scale: 1 isReg: type: integer scale: 1 genspec: type: integer scale: 1 oneToMany: extraspecs: targetEntity: ProductExtraspecs mappedBy: product Labs\CatalogBundle\Entity\ProductExtraspecs: type: entity table: orders__regmat__extraspecs fields: extraspecid: id: true type: integer unsigned: false nullable: false generator: strategy: IDENTITY regmatid: type: integer scale: 11 spec: type: integer scale: 11 attrib: type: string length: 20 value: type: string length: 200 lifecycleCallbacks: { } manyToOne: product: targetEntity: Product inversedBy: extraspecs joinColumn: name: regmatid referencedColumnName: id HOw should I do this?

  • Flex AS3: ProgressBar doesn't move

    - by jolierouge
    Hey All, I am a little stuck and need some advice/help. I have a progress bar: <mx:ProgressBar id="appProgress" mode="manual" width="300" label="{appProgressMsg}" minimum="0" maximum="100"/> I have two listener functions, one sets the progress, and one sets the appProgressMsg: public function incProgress(e:TEvent):void { var p:uint = Math.floor(e.data.number / e.data.total * 100); trace("Setting Perc." + p); appProgress.setProgress(p, 100); } public function setApplicationProgressStep(e:TEvent):void { trace("Setting step:" + e.data); appProgressMsg = e.data; } I want to reuse this progress bar alot. And not necessarily for ProgressEvents, but when going through steps. For instance, I loop over a bunch of database inserts, and want to undate the progress etc. Here is a sample: public function updateDatabase(result:Object):void { var total:int = 0; var i:int = 0; var r:SQLResult; trace("updateDatabase called."); for each (var table:XML in this.queries.elements("table")) { var key:String = table.attribute("name"); if (result[key]) { send(TEvent.UpdateApplicationProgressStep, "Updating " + key); i = 1; total = result[key].length; for each (var row:Object in result[key]) { //now, we need to see if we already have this record. send(TEvent.UpdateApplicationProgress, { number:i, total: total } ); r = this.query("select * from " + key + " where server_id = '" + row.id + "'"); if (r.data == null) { //there is no entry with this id, make one. this.query(table.insert, row); } else { //it exists, so let's update. this.update(key, row); } i++; } } } } Everything works fine. That is, the listener functions are called and I get trace output like: updateDatabase called. Setting step:Updating project Setting Perc 25 Setting Perc 50 Setting Perc 75 Setting Perc 100 The issue is, only the very last percent and step is shown. that is, when it's all done, the progress bar jumps to 100% and shows the last step label. Does anyone know why this is? Thanks in advance for any help, Jason

  • Emails sent using Flex app are delayed

    - by user363825
    I'm currently building an application in Flex that utilizes SMTP Mailer to automatically send out emails to the user when a particular condition is satisfied. The application checks this condition every 30 seconds. The condition is satisfied based on new records being returned from a database table. The problem is as follows: When the condition is first satisfied, the email is delivered to the user with no issues. The second time the condition is satisfied, the email is not delivered. In the smtp logs, the delivery attempt appears to get hung up on the following line: 354 Start mail input; end with <CRLF>.<CRLF> No error codes are present in the smtp logs, but I do trace the following event from the SMTP Mailer class: [Event type="mailError" bubbles=false cancelable=false eventPhase=2] When the condition is satisfied a third time, the email that was not delivered when the condition was satisfied the previous time is now delivered, along with the email for this instance. This pattern then repeats itself, with the next email not being sent followed by two emails being sent simulatneously when the condition is met again. The smtp server being used is Windows 2003, on an internal network. The email is being sent to an outlook account hosted on an exchange server that is also on this internal network. Here is the actionscript code that creates the SMTPMailer object: public var testMail:SMTPMailer = null; public function alertNotify() { Security.loadPolicyFile("crossdomain.xml"); this.testMail = new SMTPMailer("myserver.ec.local",25); this.testMail.addEventListener(SMTPEvent.MAIL_SENT, onEmailEvent); this.testMail.addEventListener(SMTPEvent.MAIL_ERROR, onEmailError); this.testMail.addEventListener(SMTPEvent.DISCONNECTED, onEmailConn); this.testMail.addEventListener(SecurityErrorEvent.SECURITY_ERROR, onEmailError); } Here is the code that creates the email body and calls the method to send the email: public function alertUser(emailAC:ArrayCollection):void { trace ("In alertUser() before send, testMail.connected = " + testMail.connected.toString()); var testStr:String = " Key Location Event Type Comment Update Time "; for each (var event:rEntity in emailAC) { testStr = testStr + "" + event.key.toString() + "" + event.xml.address.toString() + " " + [email protected]() + "" + [email protected]() + "" + [email protected]() + "" + event.xml.attribute("update-time").toXMLString() + ""; } testStr = testStr + ""; testMail.flush(); testMail.sendHTMLMail("[email protected]","[email protected]","Event Notification",testStr); } Really not sure where the email that gets hung up is being stored until it is finally sent.... Any suggestions as to how to begin to remedy this issue would be much appreciated.

  • Why won't this Jquery run on IE?

    - by Charles Marsh
    Hello All, I have this Jquery code (function($){ $.expr[':'].linkingToImage = function(elem, index, match){ // This will return true if the specified attribute contains a valid link to an image: return !! ($(elem).attr(match[3]) && $(elem).attr(match[3]).match(/\.(gif|jpe?g|png|bmp)$/i)); }; $.fn.imgPreview = function(userDefinedSettings){ var s = $.extend({ /* DEFAULTS */ // CSS to be applied to image: imgCSS: {}, // Distance between cursor and preview: distanceFromCursor: {top:2, left:2}, // Boolean, whether or not to preload images: preloadImages: true, // Callback: run when link is hovered: container is shown: onShow: function(){}, // Callback: container is hidden: onHide: function(){}, // Callback: Run when image within container has loaded: onLoad: function(){}, // ID to give to container (for CSS styling): containerID: 'imgPreviewContainer', // Class to be given to container while image is loading: containerLoadingClass: 'loading', // Prefix (if using thumbnails), e.g. 'thumb_' thumbPrefix: '', // Where to retrieve the image from: srcAttr: 'rel' }, userDefinedSettings), $container = $('<div/>').attr('id', s.containerID) .append('<img/>').hide() .css('position','absolute') .appendTo('body'), $img = $('img', $container).css(s.imgCSS), // Get all valid elements (linking to images / ATTR with image link): $collection = this.filter(':linkingToImage(' + s.srcAttr + ')'); // Re-usable means to add prefix (from setting): function addPrefix(src) { return src.replace(/(\/?)([^\/]+)$/,'$1' + s.thumbPrefix + '$2'); } if (s.preloadImages) { (function(i){ var tempIMG = new Image(), callee = arguments.callee; tempIMG.src = addPrefix($($collection[i]).attr(s.srcAttr)); tempIMG.onload = function(){ $collection[i + 1] && callee(i + 1); }; })(0); } $collection .mousemove(function(e){ $container.css({ top: e.pageY + s.distanceFromCursor.top + 'px', left: e.pageX + s.distanceFromCursor.left + 'px' }); }) .hover(function(){ var link = this; $container .addClass(s.containerLoadingClass) .show(); $img .load(function(){ $container.removeClass(s.containerLoadingClass); $img.show(); s.onLoad.call($img[0], link); }) .attr( 'src' , addPrefix($(link).attr(s.srcAttr)) ); s.onShow.call($container[0], link); }, function(){ $container.hide(); $img.unbind('load').attr('src','').hide(); s.onHide.call($container[0], this); }); // Return full selection, not $collection! return this; }; })(jQuery); It works perfectly in all browsers apart from IE, which it does nothing, no errors, no clues? I have a funny feeling IE doesn't support attr? Can anyone offer any advice?

  • Struggling with ASP.NET MVC auto-scaffolder template

    - by DanM
    I'm trying to write an auto-scaffolder template for Index views. I'd like to be able to pass in a collection of models or view-models (e.g., IQueryable<MyViewModel>) and get back an HTML table that uses the DisplayName attribute for the headings (th elements) and Html.Display(propertyName) for the cells (td elements). Each row should correspond to one item in the collection. Here's what I have so far: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> <% var items = (IQueryable<TestProj.ViewModels.TestViewModel>)Model; // How do I make this generic? var properties = items.First().GetMetadata().Properties .Where(pm => pm.ShowForDisplay && !ViewData.TemplateInfo.Visited(pm)); %> <table> <tr> <% foreach(var property in properties) { %> <th> <%= property.DisplayName %> </th> <% } %> </tr> <% foreach(var item in items) { HtmlHelper itemHtml = ????; // What should I put in place of "????"? %> <tr> <% foreach(var property in properties) { %> <td> <%= itemHtml.Display(property.DisplayName) %> </td> <% } %> </tr> <% } %> </table> Two problems with this: I'd like it to be generic. So, I'd like to replace var items = (IQueryable<TestProj.ViewModels.TestViewModel>)Model; with var items = (IQueryable<T>)Model; or something to that effect. A property Html is automatically created for me when the view is created, but this HtmlHelper applies to the whole collection. I need to somehow create an itemHtml object that applies just to the current item in the foreach loop. I'm not sure how to do this, however, because the constructors for HtmlHelper don't take a Model object. How do I solve these two problems?

  • JPA entity design / cannot delete entity

    - by timaschew
    I though its simple what I want, but I cannot find any solution for my problem. I'm using playframework 1.2.3 and it's using Hibernate as JPA. So I think playframework has nothing to do with the problem. I have some classes (I omit the nonrelevant fields) public class User { ... } public class Task { public DataContainer dataContainer; } public class DataContainer { public Session session; public User user; } public class Session { ... } So I have association from Task to DataContainer and from DataContainer to Sesssion and the DataContainer belongs to a User. The DataContainers can have always the same User, but the Session have to be different for each instance. And the DataContainer of a Task have also to be different in each instance. A DataContainer can have a Sesesion or not (it's optinal). I use only unidirectional assoc. It should be sufficient. In other words: Every Task must has one DataContainer. Every DataContainer must has one/the same User and can have one Session. To create a DB schema I use JPA annotations: @Entity public class User extends Model { ... } @Entity public class Task extends Model { @OneToOne(optional = false, cascade = CascadeType.ALL) public DataContainer dataContainer; } @Entity public class DataContainer extends Model { @OneToOne(optional = true, cascade = CascadeType.ALL) public Session session; @ManyToOne(optional = false, cascade = CascadeType.ALL) public User user; } @Entity public class Session extends Model { ... } BTW: Model is a play class and provides the primary id as long type. When I create some for each entity a object and 'connect them', I mean the associations, it works fine. But when I try to delete a Session, I get a constraint violation exception, because a DataContainer still refers to the Session I want to delete. I want that the Session (field) of the DataContainer will be set to null respectively the foreign key (session_id) should be unset in the database. This will be okay, because its optional. I don't know, I think I have multiple problems. Am I using the right annotation @OneToOne ? I found on the internet some additional annotation and attributes: @JoinColumn and a mappedBy attribute for the inverse relationship. But I don't have it, because its not bidirectional. Or is a bidirectional assoc. essentially? Another try was to use @OnDelete(action = OnDeleteAction.CASCADE) the the contraint changed from NO ACTIONs when update or delete to: ADD CONSTRAINT fk4745c17e6a46a56 FOREIGN KEY (session_id) REFERENCES annotation_session (id) MATCH SIMPLE ON UPDATE NO ACTION ON DELETE CASCADE; But in this case, when I delete a session, the DataContainer and User is deleted. That's wrong for me. EDIT: I'm using postgresql 9, the jdbc stuff is included in play, my only db config is db=postgres://app:app@localhost:5432/app

  • base64-Encoding breaks smime-encrypted emaildata

    - by Streuner
    I'm using Mime::Lite to create and send E-Mails. Now I need to add support for S/Mime-encryption and finally could encrypt my E-Mail (the only Perllib I could install seems broken, so I'm using a systemcall and openssl smime), but when I try to create a mime-object with it, the E-Mail will be broken as soon as I set the Content-Transfer-Encoding to base64. To make it even more curious, it happens only if I set it via $myMessage->attr. If I'm using the constructor -new everything is fine, besides a little warning which I suppress by using MIME::Lite->quiet(1); Is it a bug or my fault? Here are the two ways how I create the mime-object. Setting the Content-Transfer-Encoding via construtor and suppress the warning: MIME::Lite->quiet(1); my $msgEncr = MIME::Lite->new(From =>'[email protected]', To => '[email protected]', Subject => 'SMIME Test', Data => $myEncryptedMessage, 'Content-Transfer-Encoding' => 'base64'); $msgEncr->attr('Content-Disposition' => 'attachment'); $msgEncr->attr('Content-Disposition.filename' => 'smime.p7m'); $msgEncr->attr('Content-Type' => 'application/x-pkcs7-mime'); $msgEncr->attr('Content-Type.smime-type' => 'enveloped-data'); $msgEncr->attr('Content-Type.name' => 'smime.p7m'); $msgEncr->send; MIME::Lite->quiet(0); Setting the Content-Transfer-Encoding via $myMessage->attr which breaks the encrypted Data, but won't cause a warning: my $msgEncr = MIME::Lite->new(From => '[email protected]', To => '[email protected]', Subject => 'SMIME Test', Data => $myEncryptedMessage); $msgEncr->attr('Content-Disposition' => 'attachment'); $msgEncr->attr('Content-Disposition.filename' => 'smime.p7m'); $msgEncr->attr('Content-Type' => 'application/x-pkcs7-mime'); $msgEncr->attr('Content-Type.smime-type' => 'enveloped-data'); $msgEncr->attr('Content-Type.name' => 'smime.p7m'); $msgEncr->attr('Content-Transfer-Encoding' => 'base64'); $msgEncr->send; I just don't get why my message is broken when I'm using the attribute-setter. Thanks in advance for your help! Besides that i'm unable to attach any file to this E-Mail without breaking the encrypted message again.

  • How does Sentry aggregate errors?

    - by Hugo Rodger-Brown
    I am using Sentry (in a django project), and I'd like to know how I can get the errors to aggregate properly. I am logging certain user actions as errors, so there is no underlying system exception, and am using the culprit attribute to set a friendly error name. The message is templated, and contains a common message ("User 'x' was unable to perform action because 'y'"), but is never exactly the same (different users, different conditions). Sentry clearly uses some set of attributes under the hood to determine whether to aggregate errors as the same exception, but despite having looked through the code, I can't work out how. Can anyone short-cut my having to dig further into the code and tell me what properties I need to set in order to manage aggregation as I would like? [UPDATE 1: event grouping] This line appears in sentry.models.Group: class Group(MessageBase): """ Aggregated message which summarizes a set of Events. """ ... class Meta: unique_together = (('project', 'logger', 'culprit', 'checksum'),) ... Which makes sense - project, logger and culprit I am setting at the moment - the problem is checksum. I will investigate further, however 'checksum' suggests that binary equivalence, which is never going to work - it must be possible to group instances of the same exception, with differenct attributes? [UPDATE 2: event checksums] The event checksum comes from the sentry.manager.get_checksum_from_event method: def get_checksum_from_event(event): for interface in event.interfaces.itervalues(): result = interface.get_hash() if result: hash = hashlib.md5() for r in result: hash.update(to_string(r)) return hash.hexdigest() return hashlib.md5(to_string(event.message)).hexdigest() Next stop - where do the event interfaces come from? [UPDATE 3: event interfaces] I have worked out that interfaces refer to the standard mechanism for describing data passed into sentry events, and that I am using the standard sentry.interfaces.Message and sentry.interfaces.User interfaces. Both of these will contain different data depending on the exception instance - and so a checksum will never match. Is there any way that I can exclude these from the checksum calculation? (Or at least the User interface value, as that has to be different - the Message interface value I could standardise.) [UPDATE 4: solution] Here are the two get_hash functions for the Message and User interfaces respectively: # sentry.interfaces.Message def get_hash(self): return [self.message] # sentry.interfaces.User def get_hash(self): return [] Looking at these two, only the Message.get_hash interface will return a value that is picked up by the get_checksum_for_event method, and so this is the one that will be returned (hashed etc.) The net effect of this is that the the checksum is evaluated on the message alone - which in theory means that I can standardise the message and keep the user definition unique. I've answered my own question here, but hopefully my investigation is of use to others having the same problem. (As an aside, I've also submitted a pull request against the Sentry documentation as part of this ;-)) (Note to anyone using / extending Sentry with custom interfaces - if you want to avoid your interface being use to group exceptions, return an empty list.)
