  • WebFaultException http status code is not passed

    - by Mike Bantegui
    I have the following service method: <OperationContract()> <WebGet([ResponseFormat]:=WebMessageFormat.Json)> Function ShouldThrowException() As Boolean It's implementation does only one thing, which is to throw a WebFaultException. Public Function ShouldThrowException() As Boolean Implements IRestService.ShouldThrowException Throw New WebFaultException(Of String)("This should fail", HttpStatusCode.BadRequest) End Function My web.config reads as: <endpointBehaviors> <behavior name="WebEndpointBehavior"> <webHttp /> </behavior> </endpointBehaviors> .. snip .. <webHttpBinding> <binding name="WebBinding" crossDomainScriptAccessEnabled="true"> <security mode="None" /> </binding> </webHttpBinding> .. snip .. <service name="RestService"> <endpoint address="" binding="webHttpBinding" behaviorConfiguration="WebEndpointBehavior" bindingConfiguration="WebBinding" contract="IRestService" name="RestService"> </endpoint> </service> When I call ShouldThrowException via my browser, I only get the following: "This should fail" I was expecting to get a 400 Bad Request error on the page. If I inspect the page using FireBug, I see that the HTTP status code that was returned is a 200 OK. According to this blog post, I should be seeing this exception. Except I'm not. What am I doing wrong here?

  • How does overlayViewTouched notification work in the MoviePlayer sample code

    - by Jonathan
    Hi, I have a question regarding the MoviePlayer sample code provided by apple. I don't understand how the overlayViewTouch notification works. The NSlog message I added to it does not get sent when I touch the view (not button). // post the "overlayViewTouch" notification and will send // the overlayViewTouches: message - (void)overlayViewTouches:(NSNotification *)notification { NSLog(@"overlay view touched"); // Handle touches to the overlay view (MyOverlayView) here... } I can, however, get the NSlog notification if I place it in -(void)touchesBegan in "MyOverlayView.m". Which makes me think it is recognizing touches but not sending a notification. // Handle any touches to the overlay view - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch* touch = [touches anyObject]; if (touch.phase == UITouchPhaseBegan) { NSLog(@"overlay touched(from touchesBegan") // IMPORTANT: // Touches to the overlay view are being handled using // two different techniques as described here: // // 1. Touches to the overlay view (not in the button) // // On touches to the view we will post a notification // "overlayViewTouch". MyMovieViewController is registered // as an observer for this notification, and the // overlayViewTouches: method in MyMovieViewController // will be called. // // 2. Touches to the button // // Touches to the button in this same view will // trigger the MyMovieViewController overlayViewButtonPress: // action method instead. NSNotificationCenter *nc = [NSNotificationCenter defaultCenter]; [nc postNotificationName:OverlayViewTouchNotification object:nil]; } } Can anyone shed light on what I am missing or doing wrong? Thank you.

  • Translate an exception into 404 from Application_Error

    - by Dmitriy Nagirnyak
    Hi, First of all, quickly what exactly I want to achieve: translate particular exception into the HTTP 404 so the ASP.NET can handle it further. I am handling exceptions in the ASP.NET (MVC2) this way: protected void Application_Error(object sender, EventArgs e) { var err = Server.GetLastError(); if (err == null) return; err = err.GetBaseException(); var noObject = err as ObjectNotFoundException; if (noObject != null) HandleObjectNotFound(); var handled = noObject != null; if (!handled) Logger.Fatal("Unhandled exception has occured in application.", err); } private void HandleObjectNotFound() { Server.ClearError(); Response.Clear(); // new HttpExcepton(404, "Not Found"); // Throw or not to throw? Response.StatusCode = 404; Response.StatusDescription = "Not Found"; Response.StatusDescription = "Not Found"; Response.Write("The whole HTML body explaining whata 404 is??"); } The problem is that I cannot configure default customErrors to work with it. When it is on then it never redirects to the page specified in customErrors: <error statusCode="404" redirect="404.html"/>. I also tried to raise new HttpExcepton(404, "Not Found") from the handler but then the response code is 200 which I don't understand why. So the questions are: What is the proper way of translating AnException into HTTP 404 response? How does customErrors section work when handling exceptions in Application_Error? Why throwing HttpException(404) renders (blank) page with success (200) status? Thanks, Dmitriy.

  • Selectively suppress XML comments?

    - by Mike Post
    We deliver a number of assemblies to external customers, but not all of the public APIs are officially supported. For example, due to less than optimal design choices sometimes a type must be publicly exposed from an assembly for the rest of our code to work, but we don't want customers to use that type. One part of communicating the lack of support is not provide any intellisense in the form of XML comments. Is there a way to selectively suppress XML comments? I'm looking for something other than ignoring warning 1591 since it's a long term maintenance issue. Example: I have an assembly with public classes A and B. A is officially supported and should have XML documentation. B is not intended for external use and should not be documented. I could turn on XML documentation and then suppress warning 1591. But when I later add the officially supported class C, I want the compiler to tell me that I've screwed up and failed to add the XML documentation. This wouldn't occur if I had suppressed 1591 at the project level. I suppose I could #pragma across entire classes, but it seems like there should be a better way to do this.

  • Runtime binding of XML Schema to Java code

    - by Yaneeve
    Hi all, The situation is thus: I have an application which provides editing capabilities to XML an file. This file follows a certain Schema. The Schema belongs to a subset of Schemas which actually follow a line of evolution from one to another - so they are not so different from one another. The main difference between the schemas is an enumeration of string labels. I now have need to save "meta data" in XML format (This is a second type of XML file). This "meta data" contains a list of labels from the set enumerated in the schema. The application can accept a new schema at runtime and adjust itself. Therefore I have an XML file that must be validated by two schemas one static containing the basic structure of the "meta data" stored in the XML and one which contains the 'proper' label enumeration. The latter schema is determined at runtime. I have glanced over JAXB, XMLBeans and JiBX. I can't figure out what technology to choose that would allow for a runtime bind of code and schema in the way that would most benefit my use-case. Any suggestions? Thanks!

  • No test coverage files generated for Unit Test bundle in Xcode

    - by John Gallagher
    The Problem I've got a Cocoa project on the desktop and I'm using Xcode 3.2.1 on Snow Leopard 10.6.2. I want to generate code coverage files for my Unit Test Target in Xcode. What I've Tried As articles like this one suggest, I've adjusted the build settings to: “Generate Test Coverage Files” checked “Instrument Program Flow” checked “-lgcov” added to “Other Linker Flags” I've also set the Run Script section of the test target to have the following: # Run the unit tests in this test bundle. "${SYSTEM_DEVELOPER_DIR}/Tools/RunUnitTests" # Run gcov on the framework getting tested if [ "${CONFIGURATION}" = 'Coverage' ]; then FRAMEWORK_NAME=LapsusInterpretationEngine FRAMEWORK_OBJ_DIR=${OBJROOT}/${FRAMEWORK_NAME}.build/${CONFIGURATION}/EngineTests.build/Objects-normal/${NATIVE_ARCH} mkdir -p coverage pushd coverage find ${OBJROOT} -name *.gcda -exec gcov -o ${FRAMEWORK_OBJ_DIR} {} \; popd fi Since my Framework name is LapsusInterpretationEngine but my target is named EngineTests, I put this directly into the FRAMEWORK_OBJ_DIR but this didn't seem to help. I've tried cleaning before building. I've made sure all the above build settings apply to both the Unit Test Target and the Application Target. What I Get No .gcda or .gcno files anywhere in the build directory I'm using. I point CoverStory to the Objects-normal directory in my builds folder and it complains that there's nothing there for it to read. I must be doing something really obvious wrong. Anyone any ideas? I have tried the "EngineTests.build" directory being ${FRAMEWORK_NAME} and this gives the same results.

  • Improve Efficiency for This Text Processing Code

    - by johnv
    I am writing a program that counts the number of words in a text file which is already in lowercase and separated by spaces. I want to use a dictionary and only count the word IF it's within the dictionary. The problem is the dictionary is quite large (~100,000 words) and each text document has also ~50,000 words. As such, the codes that I wrote below gets very slow (takes about 15 sec to process one document on a quad i7 machine). I'm wondering if there's something wrong with my coding and if the efficiency of the program can be improved. Thanks so much for your help. Code below: public static string WordCount(string countInput) { string[] keywords = ReadDic(); /* read dictionary txt file*/ /*then reads the main text file*/ Dictionary<string, int> dict = ReadFile(countInput).Split(' ') .Select(c => c) .Where(c => keywords.Contains(c)) .GroupBy(c => c) .Select(g => new { word = g.Key, count = g.Count() }) .OrderBy(g => g.word) .ToDictionary(d => d.word, d => d.count); int s = dict.Sum(e => e.Value); string k = s.ToString(); return k; }

  • Project Architecture For Enhancing Legacy project.

    - by vijay.shad
    I am working on legacy project. Now the situation demands project to be divided into parts. What strategy I should follow to do this task. Description: The legacy project (A) is fully functional web application with almost well defined layers. But now i need to extend the project to a further enhancement. This project usage maven as build tool. But it is used only for dependency managements only. (project exported to war form inside eclipse). The new enhancement needs me to add new data table, new UI(jsp, css, js and images). What should be my strategy to enhance to application. My proposed design. I am planing to create two new projects Project B : Main Enhancement works will done in this project. Will have all layers like service layer, dao layer and UI layer in itself. And will be a web application in itself. Project C : Extract some common model and service code form project-A and create this project. This project will be added as dependency to both the projects. If my this approach is okay! Then i presume there will be problem be problem in deployment. These two projects will demand to deploy separately(currently tomcat is used). But I must deploy these two projects as one war. So, i need to have a plan to change the web.xml entries to have configurations for both projects. This will comes with some more complexities with project. What should be my design for the project? Does my plan sounds good.

  • Can't disable method parenthesis auto-complete in Eclipse

    - by cvig
    I'm trying to disable the automatic closing of brackets in Eclipse, and while I've mostly succeeded, I can't stop the editor from inserting a closing parenthesis for a method call. The result is that when I type: myBool.equals(true); it inserts a closing parenthesis as soon as I type the opening parenthesis, and what I actually get is: myBool.equals(true);) I've disabled all of the auto-complete options in the Preferences - Java - Editor - Typing menu, as well as Preferences - Java - Editor - Content Assist - Fill method arguments and show guessed arguments. I also disabled the smart insert mode option under the Edit menu. Is there another option somewhere else I need to use to stop Eclipse from doing this? This is with Eclipse 3.5.2 (Build ID M20100211-1343) in case it matters. Edited to add: I should also mention that this only happens if I wait for the "intellisense" pop-up with suggested method names to appear after I type the period. If I just continuously type the code without waiting for the suggestion box to appear, the closing parenthesis doesn't get inserted.

  • Datastore performance, my code or the datastore latency

    - by fredrik
    I had for the last month a bit of a problem with a quite basic datastore query. It involves 2 db.Models with one referring to the other with a db.ReferenceProperty. The problem is that according to the admin logs the request takes about 2-4 seconds to complete. I strip it down to a bare form and a list to display the results. The put works fine, but the get accumulates (in my opinion) way to much cpu time. #The get look like this: outputData['items'] = {} labelsData = Label.all() for label in labelsData: labelItem = label.item.name if labelItem not in outputData['items']: outputData['items'][labelItem] = { 'item' : labelItem, 'labels' : [] } outputData['items'][labelItem]['labels'].append(label.text) path = os.path.join(os.path.dirname(__file__), 'index.html') self.response.out.write(template.render(path, outputData)) #And the models: class Item(db.Model): name = db.StringProperty() class Label(db.Model): text = db.StringProperty() lang = db.StringProperty() item = db.ReferenceProperty(Item) I've tried to make it a number of different way ie. instead of ReferenceProperty storing all Label keys in the Item Model as a db.ListProperty. My test data is just 10 rows in Item and 40 in Label. So my questions: Is it a fools errand to try to optimize this since the high cpu usage is due to the problems with the datastore or have I just screwed up somewhere in the code? ..fredrik

  • Unit tests and Test Runner problems under .Net 4.0

    - by Brett Rigby
    Hi there, We're trying to migrate a .Net 3.5 solution into .Net 4.0, but are experiencing complications with the testing frameworks that can operate using an assembly that is built using version 4.0 of the .Net Framework. Previously, we used NUnit 2.4.3.0 and NCover 1.5.8.0 within our NAnt scripts, but NUnit 2.4.3.0 doesn't like .Net 4.0 projects. So, we upgraded to a newer version of the NUnit framework within the test project itself, but then found that NCover 1.5.8.0 doesn't support this version of NUnit. We get errors in the code saying words to the effect of the assembly was built using a newer version of the .Net Framework than is currently in use, as it's using .Net Framework 2.0 to run the tools. We then tried using Gallio's Icarus test runner GUI, but found that this and MbUnit only support up to version 3.5 of the .Net Frameword and the result is "the tests will be ignored". In terms of the coverage side of things (for reporting into CruiseControl.net), we have found that PartCover is a good candidate for substituting-out NCover, (as the newer version of NCover is quite dear, and PartCover is free), but this is a few steps down the line yet, as we can't get the test runners to work first!! Can any shed any light on a testnig framework that will run under .Net 4.0 in the same way as I've described above? If not, I fear we may have to revert back to using .Net 3.5 until the manufacturers of the tooling that we're currently using have a chance to upgrade to .Net 4.0. Thanks.

  • C sharp code cleanup : resharper

    - by Ankit Rathod
    Hello, I just used Resharper in one application and it made me feel as if i don't know how to code at all in C# :(. On every line it gave me it's suggestions :- Few of Resharper's favorite suggestions are :- 1) SomObject o = new SomeObject(); Resharper will convert to : var o = new SomeObject() 2) this.Loaded += new RoutedEventHandler(MainPage_Loaded); to this.Loaded += MainPage_Loaded; 3) convert my variables and putting _ in front of all instance variables. 4) Removing class parent's name. I tested this on Silverlight. public partial class MainPage : UserControl to public partial class MainPage EDIT :- 5) replace instance variable this.variable = somevalue to variable = somevalue Are all of these really necessary? Is it really going to affect the efficiency of my program? I mean what good is it going to do by replacing my class names with var keyword. After all var is also replaced with class name at compile time. Is it doing because it has been programmed to do or do these things really affect in some or another way? Thanks in advance :)

  • Django: how to cleanup form fields and avoid code duplication

    - by Alexander Konstantinov
    Quite often I need to filter some form data before using it (saving to database etc.) Let's say I want to strip whitespaces and replace repeating whitespaces with a single one in most of the text fields, in many forms. It's not difficult to do this using clean_<fieldname> methods: # Simplified model with two text fields class MyModel(models.Model): title = models.CharField() description = models.CharField() # Model-based form class MyForm(forms.ModelForm): class Meta: model = MyModel def clean_title(self): title = self.cleaned_data['title'] return re.sub(r'\s{2,}', ' ', title.strip()) def clean_description(self): description = self.cleaned_data['description'] return re.sub(r'\s{2,}', ' ', description.strip()) It does exactly what I need, and has a nice side effect which I like: if user enters only whitespaces, the field will be considered empty and therefore invalid (if it is required) and I don't even have to throw a ValidationError. The obvious problem here is code duplication. Even if I'll create some function for that, say my_text_filter, I'll have to call it for every text field in all my forms: from myproject.filters import my_text_filter class MyForm(forms.ModelForm): class Meta: model = MyModel def clean_title(self): return my_text_filter(self.cleaned_data['title']) def clean_description(self): return my_text_filter(self.cleaned_data['description']) The question: is there any standard and simple way in Django (I use version 1.2 if that matters) to do this (like, for example, by adding property validators = {'title': my_text_filter, 'description': my_text_filter} to MyModel), or at least some more or less standard workaround? I've read about form validation and validators in the documentation, but couldn't find what I need there.

  • How to run some code only once in view

    - by Freewind
    I have a partial view called '_comment.erb', and it may be called by parent many times(e.g. in a loop). The '_comment.erb' looks like: <script> function aaa() {} </script> <%= comment.content %> <%=link_to_function 'Do', 'aaa()' %> You can see if the '_comment.erb' be called many times, that the javascript function 'aaa' will be re-defined many times. I hope it can be define only once, but I don't want to move it to parent view. I hope there is a method, say 'run_once', and I can use it like this: <%= run_once do %> <script> function aaa() {} </script> <% end %> <%= comment.content %> <%=link_to_function 'Do', 'aaa()' %> No matter how many time I call the '_comment.erb', the code inside 'run_once' will be run only once. What shall I do?

  • Pseudo code for instruction description

    - by Claus
    Hi, I am just trying to fiddle around what is the best and shortest way to describe two simple instructions with C-like pseudo code. The extract instruction is defined as follows: extract rd, rs, imm This instruction extracts the appropriate byte from the 32-bit source register rs and right justifies it in the destination register. The byte is specified by imm and thus can take the values 0 (for the least-significant byte) and 3 (for the most-significant byte). rd = 0x0; // zero-extend result, ie to make sure bits 31 to 8 are set to zero in the result rd = (rs && (0xff << imm)) >> imm; // this extracts the approriate byte and stores it in rd The insert instruction can be regarded as the inverse operation and it takes a right justified byte from the source register rs and deposits it in the appropriate byte of the destination register rd; again, this byte is determined by the value of imm tmp = 0x0 XOR (rs << imm)) // shift the byte to the appropriate byte determined by imm rd = (rd && (0x00 << imm)) // set appropriate byte to zero in rd rd = rd XOR tmp // XOR the byte into the destination register This looks all a bit horrible, so I wonder if there is a little bit a more elegant way to describe this bahaviour in C-like style ;) Many thanks, Claus

  • Munging non-printable characters to dots using string.translate()

    - by Jim Dennis
    So I've done this before and it's a surprising ugly bit of code for such a seemingly simple task. The goal is to translate any non-printable character into a . (dot). For my purposes "printable" does exclude the last few characters from string.printable (new-lines, tabs, and so on). This is for printing things like the old MS-DOS debug "hex dump" format ... or anything similar to that (where additional whitespace will mangle the intended dump layout). I know I can use string.translate() and, to use that, I need a translation table. So I use string.maketrans() for that. Here's the best I could come up with: filter = string.maketrans( string.translate(string.maketrans('',''), string.maketrans('',''),string.printable[:-5]), '.'*len(string.translate(string.maketrans('',''), string.maketrans('',''),string.printable[:-5]))) ... which is an unreadable mess (though it does work). From there you can call use something like: for each_line in sometext: print string.translate(each_line, filter) ... and be happy. (So long as you don't look under the hood). Now it is more readable if I break that horrid expression into separate statements: ascii = string.maketrans('','') # The whole ASCII character set nonprintable = string.translate(ascii, ascii, string.printable[:-5]) # Optional delchars argument filter = string.maketrans(nonprintable, '.' * len(nonprintable)) And it's tempting to do that just for legibility. However, I keep thinking there has to be a more elegant way to express this!

I mean that I have to scroll down to see bottom. Any ideas?
