  • Cannot integrate Gallio MBUnit with Team City

    - by Bernard Larouche
    I have been trying to get my MBUnit tests suite to work on Team City for many days now without any success. My solution builds no problem. The program is with my tests. After googling for Gallio integration with Team City I tried many ways to make this thing work and I think I am close but need help. I have included the gallio bin directory to my repository and also on my TC Server. Here is my build runner set up in Team City : Build runner : MSBuild Build file path : Myproject.msbuild Targets : RebuildSolution RunTests Here is Myproject.msbuild file I created and included in the Source control trunk directory : <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <!-- This is needed by MSBuild to locate the Gallio task --> <UsingTask AssemblyFile="C:\Gallio\bin\Gallio.MSBuildTasks.dll" TaskName="Gallio" /> <!-- Specify the tests assemblies --> <ItemGroup> <TestAssemblies Include="C:\_CBL\CBL\CoderForTraders\Source\trunk\UnitTest\DomainModel.Tests\bin\Debug\CBL.CoderForTraders.DomainModel.Tests.dll" /> </ItemGroup> <Target Name="RunTests"> <Gallio IgnoreFailures="false" Assemblies="@(TestAssemblies)" RunnerExtensions="TeamCityExtension,Gallio.TeamCityIntegration"> <!-- This tells MSBuild to store the output value of the task's ExitCode property into the project's ExitCode property --> <Output TaskParameter="ExitCode" PropertyName="ExitCode"/> </Gallio> <Error Text="Tests execution failed" Condition="'$(ExitCode)' != 0" /> </Target> <Target Name="RebuildSolution"> <Message Text="Starting to Build"/> <MSBuild Projects="CoderForTraders.sln" Properties="Configuration=Debug" Targets="Rebuild" /> </Target> </Project> Here are the errors displayed by Team City : error MSB4064: The "Assemblies" parameter is not supported by the "Gallio" task. Verify the parameter exists on the task, and it is a settable public instance property error MSB4063: The "Gallio" task could not be initialized with its input parameters. Thanks for your help

  • Data validation best practices: how can I better construct user feedback?

    - by Cory Larson
    Data validation, whether it be domain object, form, or any other type of input validation, could theoretically be part of any development effort, no matter its size or complexity. I sometimes find myself writing informational or error messages that might seem harsh or demanding to unsuspecting users, and frankly I feel like there must be a better way to describe the validation problem to the user. I know that this topic is subjective and argumentative. StackOverflow might not be the proper channel for diving into this subject, but like I've mentioned, we all run into this at some point or another. There are so many StackExchange sites now; if there is a better one, feel free to share! Basically, I'm looking for good resources on data validation and user feedback that results from it at a theoretical level. Topics and questions I'm interested in are: Content Should I be describing what the user did correctly or incorrectly, or simply what was expected? How much detail can the user read before they get annoyed? (e.g. Is "Username cannot exceed 20 characters." enough, or should it be described more fully, such as "The username cannot be empty, and must be at least 6 characters but cannot exceed 30 characters."?) Grammar How do I decide between phrases like "must not," "may not," or "cannot"? Delivery This can depend on the project, but how should the information be delivered to the user? Should it be obtrusive (e.g. JavaScript alerts) or friendly? Should they be displayed prominently? Immediately (i.e. without confirmation steps, etc.)? Logging Do you bother logging validation errors? Internationalization Some cultures prefer or better understand directness over subtlety and vice-versa (e.g. "Don't do that!" vs. "Please check what you've done."). How do I cater to the majority of users? I may edit this list as I think more about the topic, but I'm genuinely interest in proper user feedback techniques. I'm looking for things like research results, poll results, etc. I've developed and refined my own techniques over the years that users seem to be okay with, but I work in an environment where the users prefer to adapt to what you give them over speaking up about things they don't like. I'm interested in hearing your experiences in addition to any resources to which you may be able to point me.

  • Configure PERL DBI and DBD in Linux

    - by Balualways
    I am new to Perl and I work in a Linux OEL 5x server. I am trying to configure the Perl DB modules for Oracle connectivity (DBD and DBI modules).

  • Windows Service Hosting WCF Objects over SSL (https) - Custom JSON Error Handling Doesn't Work

    - by bpatrick100
    I will first show the code that works in a non-ssl (http) environment. This code uses a custom json error handler, and all errors thrown, do get bubbled up to the client javascript (ajax). // Create webservice endpoint WebHttpBinding binding = new WebHttpBinding(); ServiceEndpoint serviceEndPoint = new ServiceEndpoint(ContractDescription.GetContract(Type.GetType(svcHost.serviceContract + ", " + svcHost.assemblyName)), binding, new EndpointAddress(svcHost.hostUrl)); // Add exception handler serviceEndPoint.Behaviors.Add(new FaultingWebHttpBehavior()); // Create host and add webservice endpoint WebServiceHost webServiceHost = new WebServiceHost(svcHost.obj, new Uri(svcHost.hostUrl)); webServiceHost.Description.Endpoints.Add(serviceEndPoint); webServiceHost.Open(); I'll also show you what the FaultingWebHttpBehavior class looks like: public class FaultingWebHttpBehavior : WebHttpBehavior { public FaultingWebHttpBehavior() { } protected override void AddServerErrorHandlers(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher) { endpointDispatcher.ChannelDispatcher.ErrorHandlers.Clear(); endpointDispatcher.ChannelDispatcher.ErrorHandlers.Add(new ErrorHandler()); } public class ErrorHandler : IErrorHandler { public bool HandleError(Exception error) { return true; } public void ProvideFault(Exception error, MessageVersion version, ref Message fault) { // Build an object to return a json serialized exception GeneralFault generalFault = new GeneralFault(); generalFault.BaseType = "Exception"; generalFault.Type = error.GetType().ToString(); generalFault.Message = error.Message; // Create the fault object to return to the client fault = Message.CreateMessage(version, "", generalFault, new DataContractJsonSerializer(typeof(GeneralFault))); WebBodyFormatMessageProperty wbf = new WebBodyFormatMessageProperty(WebContentFormat.Json); fault.Properties.Add(WebBodyFormatMessageProperty.Name, wbf); } } } [DataContract] public class GeneralFault { [DataMember] public string BaseType; [DataMember] public string Type; [DataMember] public string Message; } The AddServerErrorHandlers() method gets called automatically, once webServiceHost.Open() gets called. This sets up the custom json error handler, and life is good :-) The problem comes, when we switch to and SSL (https) environment. I'll now show you endpoint creation code for SSL: // Create webservice endpoint WebHttpBinding binding = new WebHttpBinding(); ServiceEndpoint serviceEndPoint = new ServiceEndpoint(ContractDescription.GetContract(Type.GetType(svcHost.serviceContract + ", " + svcHost.assemblyName)), binding, new EndpointAddress(svcHost.hostUrl)); // This exception handler code below (FaultingWebHttpBehavior) doesn't work with SSL communication for some reason, need to resarch... // Add exception handler serviceEndPoint.Behaviors.Add(new FaultingWebHttpBehavior()); //Add Https Endpoint WebServiceHost webServiceHost = new WebServiceHost(svcHost.obj, new Uri(svcHost.hostUrl)); binding.Security.Mode = WebHttpSecurityMode.Transport; binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None; webServiceHost.AddServiceEndpoint(svcHost.serviceContract, binding, string.Empty); Now, with this SSL endpoint code, the service starts up correctly, and wcf hosted objects can be communicated with just fine via client javascript. However, the custom error handler doesn't work. The reason is, the AddServerErrorHandlers() method never gets called when webServiceHost.Open() is run. So, can anyone tell me what is wrong with this picture? And why, is AddServerErrorHandlers() not getting called automatically, like it does when I'm using non-ssl endpoints? Thanks!

  • JNDI / Classpath problem in glassfish

    - by Michael Borgwardt
    I am in the process of converting a large J2EE app from EJB 2 to EJB 3 (all stateless session beans, using glassfish 2.1.1), and running out of ideas. The first EJB I converted (let's call it Foo) ran without major problems (it was the only one in its ejb-module and I could completely replace the deployment descriptor with annotations) and the app ran fine. But after converting the second one (let's call it Bar, one of several in a different ejb-module) there is a weird combination of problems: The app deploys without errors (nothing in the logs either) There is an error when looking up Bar via JNDI When looking at the JNDI tree in the glassfish admin console, Bar is not present at all. Then when I look at the logs, I see this (Foo is the correct name of the EJB's remote interface of the first converted, previously working EJB): Caused by: javax.naming.NamingException: ejb ref resolution error for remote business interface Foo [Root exception is java.lang.ClassNotFoundException: Foo] at com.sun.ejb.EJBUtils.lookupRemote30BusinessObject(EJBUtils.java:425) at com.sun.ejb.containers.RemoteBusinessObjectFactory.getObjectInstance(RemoteBusinessObjectFactory.java:74) at javax.naming.spi.NamingManager.getObjectInstance(NamingManager.java:304) at com.sun.enterprise.naming.SerialContext.lookup(SerialContext.java:414) at com.sun.enterprise.naming.SerialContext.list(SerialContext.java:603) at javax.naming.InitialContext.list(InitialContext.java:395) at com.sun.enterprise.admin.monitor.jndi.JndiMBeanHelper.getJndiEntriesByContextPath(JndiMBeanHelper.java:106) at com.sun.enterprise.admin.monitor.jndi.JndiMBeanImpl.getNames(JndiMBeanImpl.java:231) ... 68 more Caused by: java.lang.ClassNotFoundException: XXX at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1578) at com.sun.ejb.EJBUtils.getBusinessIntfClassLoader(EJBUtils.java:679) at com.sun.ejb.EJBUtils.lookupRemote30BusinessObject(EJBUtils.java:348) ... 75 more This is followed by more exceptions for all the entries that (like Foo) do appear in the JNDI tree. These look like this: Caused by: javax.naming.NotContextException: BarHome cannot be listed at com.sun.enterprise.naming.SerialContext.list(SerialContext.java:607) at javax.naming.InitialContext.list(InitialContext.java:395) at com.sun.enterprise.admin.monitor.jndi.JndiMBeanHelper.getJndiEntriesByContextPath(JndiMBeanHelper.java:106) at com.sun.enterprise.admin.monitor.jndi.JndiMBeanImpl.getNames(JndiMBeanImpl.java:231) ... 68 more However, no exception for Bar, it does not appear in the log at all except one entry during deployment. The other EJBs in the same module do appear, as does Foo. Any ideas what could cause this or how to diagnose it further? The beans are pretty straightforward: @Stateless(name = "Foo") @RolesAllowed("FOOUSER") @TransactionAttribute(TransactionAttributeType.SUPPORTS) public class FooImpl extends BaseBean implements Foo { I'm also having some problems with the deployment descriptor for Bar (I'd like to eliminate it, but glassfish doesn't seem to like having a bean appear only in sun-ejb-jar.xml, or having some beans in a module declared in the descriptor and others use only annotations), but I can't see how that could cause the ClassNotFoundException on Foo. Is there a way to see the ClassPath that Glassfish is actually using?

  • Autoconf (newbie) -- building with static library

    - by EB
    I am trying to migrate from manual build to autoconf, which is working very nicely so far. But I have one static library that I can't figure out how to integrate. That library will NOT be located in the usual library locations - the location of the binary (.a file) and header (.h file) will be given as a configure argument. (Notably, even if I move the .a file to /usr/lib or anywhere else I can think of, it still won't work.) Manual compilation is working with these: gcc ... -I/path/to/header/file/directory /full/path/to/the/.a/file/itself (Uh, I actually don't understand why the .a file is referenced directly, not with -L or anything. Yes, I have a half-baked understanding of building C programs.) I can use the configure argument to successfully find the header (.h file) using AC_CHECK_HEADER. Inside the AC_CHECK_HEADER I then add the location to CPFLAGS and the #include of the header file in the actual C code picks it up nicely. Given a configure argument that has been put into $location and the name of the needed files are myprog.h and myprog.a (which are both in the same directory), here is what works so far: AC_CHECK_HEADER([$location/myprog.h], [AC_DEFINE([HAVE_MYPROG_H], [1], [found myprog.h]) CFLAGS="$CFLAGS -I$location"]) Where I run into difficulties is getting the binary (.a file) linked in. No matter what I try, I always get an error about undefined references to the function calls for that library. I'm pretty sure it's a linkage issue, because I can fuss with the C code and make an intentional error in the function calls to that library which produces earlier errors that indicate that the function prototypes have been loaded and used to compile. I tried adding the location that contains the .a file to LDFLAGS and then doing a AC_CHECK_LIB but it is not found. Maybe my syntax is wrong, or maybe I'm missing something more fundamental, which would not be surprising since I'm a newbie and don't really know what I'm doing. Here is what I have tried: AC_CHECK_HEADER([$location/myprog.h], [AC_DEFINE([HAVE_MYPROG_H], [1], [found myprog.h]) CFLAGS="$CFLAGS -I$location"; LDFLAGS="$LDFLAGS -L$location"; AC_CHECK_LIB(myprog)]) No dice. AC_CHECK_LIB is looking for -lmyprog I guess (or libmyprog?) so I'm not sure if that's a problem, so I tried this, too (omit AC_CHECK_LIB and include the .a directly in LDFLAGS), without luck: AC_CHECK_HEADER([$location/myprog.h], [AC_DEFINE([HAVE_MYPROG_H], [1], [found myprog.h]) CFLAGS="$CFLAGS -I$location"; LDFLAGS="$LDFLAGS -L$location/myprog.a"]) To emulate the manual compilation, I tried removing the -L but that doesn't help: AC_CHECK_HEADER([$location/myprog.h], [AC_DEFINE([HAVE_MYPROG_H], [1], [found myprog.h]) CFLAGS="$CFLAGS -I$location"; LDFLAGS="$LDFLAGS $location/myprog.a"]) I tried other combinations and permutations, but I think I might be missing something more fundamental....

  • Filter chain halted as [:login_required] rendered_or_redirected

    - by Magicked
    Hopefully I can explain this well enough, but please let me know if more information is needed! I'm building a form where a user can create an "incident". This incident has the following relationships: belongs_to: customer (customer has_many incidents) belongs_to: user (user has_many incidents) has_one: incident_status (incident_status belongs to incident) The form allows the user to assign the incident to a user (select form) and then select an incident status. The incident is nested in customer. However, I'm getting the following in the server logs: Processing IncidentsController#create (for 127.0.0.1 at 2010-04-26 10:41:33) [POST] Parameters: {"commit"=>"Create", "action"=>"create", "authenticity_token"=>"YhW++vd/dnLoNV/DSl1DULcaWq/RwP7jvLOVx9jQblA=", "customer_id"=>"4", "controller"=>"incidents", "incident"=>{"title"=>"Some Bad Incident", "incident_status_id"=>"1", "user_id"=>"2", "other_name"=>"SS01-042310-001"}} User Load (0.3ms) SELECT * FROM "users" WHERE ("users"."id" = 2) LIMIT 1 Redirected to http://localhost:3000/session/new Filter chain halted as [:login_required] rendered_or_redirected. Completed in 55ms (DB: 0) | 302 Found [http://localhost/customers/4/incidents] It looks to me like it's trying to gather information about the user, even though it already has the id (which is all it needs to create the incident), and the user may not have permission to do a select statement like that? I'm rather confused. Here is the relevant (I think) information in the Incident controller. before_filter :login_required, :get_customer def new @incident = @customer.incidents.build @users = @customer.users @statuses = IncidentStatus.find(:all) respond_to do |format| format.html # new.html.erb format.xml { render :xml => @incident } end end def create @incident = @customer.incidents.build(params[:incident]) respond_to do |format| if @incident.save flash[:notice] = 'Incident was successfully created.' format.html { redirect_to(@incident) } format.xml { render :xml => @incident, :status => :created, :location => @incident } else format.html { render :action => "new" } format.xml { render :xml => @incident.errors, :status => :unprocessable_entity } end end end Just as an FYI, I am using the restful_authentication plugin. So in summary, when I submit the incident creation form, it does not save the incident because it halts. I'm still very new to rails, so my skill at diagnosing problems like this is still very bad. I'm going in circles. :) Thanks in advance for any help. Please let me know if more information is needed and I'll edit it in!

  • System.IO.IOException: file used by another process

    - by Srodriguez
    Dear all, I've been working in this small piece of code that seems trivial but still i cannot really see where is the problem. My functions does a pretty simple thing. Opens a file, copy its contents, replace a string inside and copy it back to the original file (a simple search and replace inside a text file then). I didn't really know how to do that as I'm adding lines to the original file, so i just create a copy of the file, (file.temp) copy also a backup (file.temp) then delete the original file(file) and copy the file.temp to file. I get an exception while doing the delete of the file. Here is the sample code: private static bool modifyFile(FileInfo file, string extractedMethod, string modifiedMethod) { Boolean result = false; FileStream fs = new FileStream(file.FullName + ".tmp", FileMode.Create, FileAccess.Write); StreamWriter sw = new StreamWriter(fs); StreamReader streamreader = file.OpenText(); String originalPath = file.FullName; string input = streamreader.ReadToEnd(); Console.WriteLine("input : {0}", input); String tempString = input.Replace(extractedMethod, modifiedMethod); Console.WriteLine("replaced String {0}", tempString); try { sw.Write(tempString); sw.Flush(); sw.Close(); sw.Dispose(); fs.Close(); fs.Dispose(); streamreader.Close(); streamreader.Dispose(); File.Copy(originalPath, originalPath + ".old", true); FileInfo newFile = new FileInfo(originalPath + ".tmp"); File.Delete(originalPath); File.Copy(fs., originalPath, true); result = true; } catch (Exception ex) { Console.WriteLine(ex); } return result; }` And the related exception System.IO.IOException: The process cannot access the file 'E:\mypath\myFile.cs' because it is being used by another process. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.File.Delete(String path) at callingMethod.modifyFile(FileInfo file, String extractedMethod, String modifiedMethod) Normally these errors come from unclosed file streams, but I've taken care of that. I guess I've forgotten an important step but cannot figure out where. Thank you very much for your help,

  • Encoding in Scene Builder

    I generate an FXML file with Scene Builder. I need it to contain some cirillic text. When i edit this file with Scene Builder i can see normal cirillic letters (screen 1) After compileing and running my program with this FXML file, i'll see not cirillic letters, but some artefacts (screen 2) But, as you can see on the screen 3, its xml file encoding is UTF-8. Also, you can see there that it is saved in ANSI. I've tried to open it with other editors (default eclipse and sublime text 2) and they shoen wrong encoding either. (screen 4 and screen 5) At first i've tried to convert it from ansi to utf-8 (with notepad++). After that eclipse and sublime text 2 started display cirillic letters as they must be. But. Scene builder gave an error, when i've tried to open this file with it: Error loading file C:\eclipse\workspace\equification\src\main\java\ru\igs\ava\equification\test.fxml. C:\eclipse\workspace\equification\src\main\java\ru\igs\ava\equification\test.fxml:1: ParseError at [row,col]:[1,1] Message: Content is not allowed in prolog.

And, having this file in ANSI, changed its "artefacted" text to cirillic letters manually. Now i can see normal text when i run my program, but when i open this fixed file via Scene Builder, Scene Builder shows me some "artefacted" text (screen 7). So, how can i fix this situation?

Any suggestions other then running the application in 32 bit only? Please do not dilute the feedback by asking for or blaming the code, the code is 100% solid, guaranteed! No memory leaks, the crashes clearly are triggered in 32 bit mode only just after start inside the AppKit itself like deep inside NSThread sleep's callstack.

  • Access violation when accessing a COM object from .Net

    - by Groo
    Dear Sirs, I am sorry if the post is too long, but I would be happy if someone would at least point read the bolded titles, and point me in the right direction. I am having this problem for couple of days, but was unable to found the answer on the net. These are the things I have found out so far. 1. "Access violation" exception crushes my managed application My C# WinForms app sometimes closes with an "Access violation" exception ("Attempted to read or write protected memory"), right in the moment when selecting a TabPage in a windows form TabControl. From the stack trace (try/catch around Application.Run) I can see that the exception happens at System.Windows.Forms.UnsafeNativeMethods.DispatchMessageW(MSG& msg), called inside UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop(Int32 dwComponentID, Int32 reason, Int32 pvLoopData). -- Message: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. -- Stack trace: at System.Windows.Forms.UnsafeNativeMethods.DispatchMessageW(MSG& msg) at System.Windows.Forms.Application.ComponentManager .System.Windows.Forms.UnsafeNativeMethods .IMsoComponentManager.FPushMessageLoop (Int32 dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.Application.ThreadContext .RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.ThreadContext .RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run(ApplicationContext context) at MyApp.Program.Main() 2. The faulting module seems to be a COM object (ChartFX Client Server 6.2) Using WinDbg (with SoS loaded), I caught it on the unmanaged side, inside ChartFX.ClientServer.Core.dll (that's a COM charting component we are using): (ca84.c98c): Access violation - code c0000005 (first chance) First chance exceptions are reported before any exception handling. This exception may be expected and handled. eax=00000000 ebx=06e67c38 ecx=06e67c38 edx=000018c6 esi=06e7df30 edi=317a9e80 eip=31666110 esp=0015e040 ebp=0015e08c iopl=0 nv up ei pl zr na pe nc cs=001b ss=0023 ds=0023 es=0023 fs=003b gs=0000 efl=00010246 ChartFX_ClientServer_Core!Ordinal5507+0x97b7: 31666110 8a404d mov al,byte ptr [eax+4Dh] ds:0023:0000004d=??

Bug is not easy to reproduce (although it can be provoked usually in less than 5 min.) I have several Chart instances in several TabPages, and this usually happens while I am switching the tabs. I still don't know how to reproduce it, besides switching those tabs for several minutes before it happens, so I cannot use our source control to reliably find the build which didn't have this problem. I am accessing the charts through the managed AxChart wrapper class (derived from AxHost), which was created by VS designer automatically. 4. What should be my next step? If someone could point me to the next step I should do to find the actual cause, I would be very grateful. Experimenting (removing and returning code) does not do much good, because I don't know how to reproduce it, so it would take large amounts of time on each iteration just to convince myself that the bug is still there. I have found that people often suggest something like "switching compiler optimizations", but since the exception is not thrown deterministically, I don't want to simply rearrange some bytes and hope that it never returns. Thanks a lot in advance! Best regards, Groo

  • Is this question too hard for a seasoned C++ architect?

    - by Monomer
    Background Information We're looking to hire a seasoned C++ architect (10+years dev, of which at least 6years must be C++ ) for a high frequency trading platform. Job advert says STL, Boost proficiency is a must with preferences to modern uses of C++. The company I work for is a Fortune 500 IB (aka finance industry), it requires passes in all the standard SHL tests (numeric, vocab, spatial etc) before interviews can commence. Everyone on the team was given the task of coming up with one question to ask the candidates during a written/typed test, please note this is the second test provided to the candidates, the first being Advanced IKM C++ test, done in the offices supervised and without internet access. People passing that do the second test. After roughly 70 candidates, my question has been determined to be statistically the worst performing - aka least number of people attempted it, furthermore even less people were able to give meaningful answers. Please note, the second test is not timed, the candidate can literally take as long as they like (we've had one person take roughly 10.5hrs) My question to SO is this, after SHL and IKM adv c++ tests, backed up with at least 6+ years C++ development experience, is it still ok not to be able to even comment about let alone come up with some loose strategy for solving the following question. The Question There is a class C with methods foo, boo, boo_and_foo and foo_and_boo. Each method takes i,j,k and l clock cycles respectively, where i < j, k < i+j and l < i+j. class C { public: int foo() {...} int boo() {...} int boo_and_foo() {...} int foo_and_boo() {...} }; In code one might write: C c; . . int i = c.foo() + c.boo(); But it would be better to have: int i = c.foo_and_boo(); What changes or techniques could one make to the definition of C, that would allow similar syntax of the original usage, but instead have the compiler generate the latter. Note that foo and boo are not commutative. Possible Solution We were basically looking for an expression templates based approach, and were willing to give marks to anyone who had even hinted or used the phrase or related terminology. We got only two people that used the wording, but weren't able to properly describe how they accomplish the task in detail. We use such techniques all over the place, due to the use of various mathematical operators for matrix and vector based calculations, for example to decide when to use IPP or hand woven implementations at compile time for a particular architecture and many other things. The particular area of software development requires microsecond response times. I believe could/should be able to teach a junior such techniques, but given the assumed caliber of candidates I expected a little more. Is this really a difficult question? Should it be removed? Or are we just not seeing the right candidates?

  • What should I do when the managed object context fails to save?

    - by dontWatchMyProfile
    Example: I have an Cat entity with an catAge attribute. In the data modeler, I configured catAge as int with a max of 100. Then I do this: [newManagedObject setValue:[NSNumber numberWithInt:125] forKey:@"catAge"]; // Save the context. NSError *error = nil; if (![context save:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); } I'm getting an error in the console, like this: 2010-06-12 11:40:41.947 CatTest[2250:207] Unresolved error Error Domain=NSCocoaErrorDomain Code=1610 UserInfo=0x10164d0 "Operation could not be completed. (Cocoa error 1610.)", { NSLocalizedDescription = "Operation could not be completed. (Cocoa error 1610.)"; NSValidationErrorKey = catAge; NSValidationErrorObject = <NSManagedObject: 0x10099f0> (entity: Cat; id: 0x1006a90 <x-coredata:///Cat/t3BCBC34B-8405-4F16-B591-BE804B6811562> ; data: { catAge = 125; catName = "No Name"; }); NSValidationErrorPredicate = SELF <= 100; NSValidationErrorValue = 125; } Well, so I have an validation error. But the odd thing is, that it seems the MOC is broken after this. If I just tap "add" to add another invalid Cat object and save that, I'm getting this: 2010-06-12 11:45:13.857 CatTest[2250:207] Unresolved error Error Domain=NSCocoaErrorDomain Code=1560 UserInfo=0x1232170 "Operation could not be completed. (Cocoa error 1560.)", { NSDetailedErrors = ( Error Domain=NSCocoaErrorDomain Code=1610 UserInfo=0x1215f00 "Operation could not be completed. (Cocoa error 1610.)", Error Domain=NSCocoaErrorDomain Code=1610 UserInfo=0x1209fc0 "Operation could not be completed. (Cocoa error 1610.)" ); } That seems to report two errors now. BUT: When I try to delete now an valid, existing object from the table view (using the default core data template in a navigation-based app), then the app crashes! All I get in the console is: 2010-06-12 11:47:18.931 CatTest[2250:207] Unresolved error Error Domain=NSCocoaErrorDomain Code=1560 UserInfo=0x123eb30 "Operation could not be completed. (Cocoa error 1560.)", { NSDetailedErrors = ( Error Domain=NSCocoaErrorDomain Code=1610 UserInfo=0x1217010 "Operation could not be completed. (Cocoa error 1610.)", Error Domain=NSCocoaErrorDomain Code=1610 UserInfo=0x123ea80 "Operation could not be completed. (Cocoa error 1610.)" ); } ...so no idea where or why it crashes, but it does. So the question is, what are the neccessary steps to take when there's an validation error?

  • Get from Android BroadcastReciever to a UI

    - by Andy
    I have a reciever that works well, but I can't seem to show a proper UI, although the toast appears correctly. As far as I can tell, this is caused by Android requiring the class to extend Activity, however, the class already extends BroadcastReciever, so I can't do this. So, I tried to do an Intent, but this failed too. There are no errors, but the screen doesn't show. Source code is below, and any help would be most appreciated. Reciever public class Reciever extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Toast.makeText(context, "Alarm Recieved", Toast.LENGTH_LONG).show(); Intent i = new Intent(); i.setClass(context, AlarmRing.class); } } AlarmRing public class AlarmRing extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.alarm); MediaPlayer mp = MediaPlayer.create(getBaseContext(), R.raw.sweetchild); mp.start(); } Manifest <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.comaad.andyroidalarm" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".AndyRoidAlarm" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <receiver android:name="com.comaad.andyroidalarm.Reciever" android:enabled="true"> <intent-filter> <action android:name="com.comaad.andyroidalarm.Reciever"></action> </intent-filter> </receiver> <activity android:name=".AlarmRing"></activity> </application> </manifest> }

  • Ajax comments form in ASP.NET MVC2, howto?

    - by Artiom Chilaru
    I've been playing around with different aspects of MVC for some time now, and I've reached a situation where I'm not sure what would be the best way to solve a problem. I'm hoping that the SO community will help me out here :P I've seen a number of examples of Ajax.BeginForm on the internet, and it seems like a very nifty idea. E.g. you have a dropdown where you select a customer - and on selecting one it will load this client's details in some placeholder on the page. This works perfectly fine. But what to do if you want to tie in some validation in the box? Just hypothetically, imagine an article page, and user comments in the bottom. Below the comments area there's an ajax-y "Add comment" box. When a user adds a comment, it will appear in the comments area, below the last comment there. If I set the Ajax.BeginForm to Append the result of the call to the Comments area, it will work fine. But what if the data posted is not valid? Instead of appending a "successful" comment to the comments area I have to show the user validation errors. At this point I decided that the area INSIDE the Ajax.BeginForm will be inside a partial, and the form's submits will return this partial. Validation works fine. On each submit we reload the contents inside the form element. But how to add the successful comment to the top? Other things to consider: The comment form also has a "Preview" button. When the user clicks on Preview, I should load the rendered comment into a preview box. This will probably be inside the form area as well. I was thinking of using Json results instead. When the user submits the form, the server code will generate a Json object with a Success value, and html rendered partials as some properties. Something like { "success": true, "form": "<html form data>", "comment": "successful comment html to inject into the page" } This would be a perfect solution, except there's no way in MVC to render a partial into a string, inside the controller (separation of context, remember?). So.. what should I do then? Any "correct" way to implement this? Anyone???

  • CCNet web dashboard not showing anything when MSBuild fails

    - by cfdev9
    I have a simple project in ccnet using svn & msbuild only. There is a 30 second trigger for svn and the msbuild file compiles a web application then copies it to a numbered build folder. When an error occurs in the msbuild task I get a failed build. When I view a failed build in the web dashboard I can see the 'Modifications since last build' section in the dashboard, but nothing else. I have to click on the build log and read through all of the xml in the error log to see what the error was. Why won't the dashboard show the errors from the build log? I haven't changed anything in the dashboard.config since installing ccnet.

  • How do I work around this problem creating a virtualenv environment with a custom-build Python?

    - by Daryl Spitzer
    I need to run some code on a Linux machine with Python 2.3.4 pre-installed. I'm not on the sudoers list for that machine, so I built Python 2.6.4 into (a subdirectory in) my home directory.

  • PHP: Can pcntl_alarm() and socket_select() peacefully exist in the same thread?

    - by DWilliams
    I have a PHP CLI script mostly written that functions as a chat server for chat clients to connect to (don't ask me why I'm doing it in PHP, thats another story haha). My script utilizes the socket_select() function to hang execution until something happens on a socket, at which point it wakes up, processes the event, and waits until the next event. Now, there are some routine tasks that I need performed every 30 seconds or so (check of tempbanned users should be unbanned, save user databases, other assorted things). From what I can tell, PHP doesn't have very great multi-threading support at all. My first thought was to compare a timestamp every time the socket generates an event and gets the program flowing again, but this is very inconsistent since the server could very well sit idle for hours and not have any of my cleanup routines executed. I came across the PHP pcntl extensions, and it lets me use assign a time interval for SIGALRM to get sent and a function get executed every time it's sent. This seems like the ideal solution to my problem, however pcntl_alarm() and socket_select() clash with each other pretty bad. Every time SIGALRM is triggered, all sorts of crazy things happen to my socket control code. My program is fairly lengthy so I can't post it all here, but it shouldn't matter since I don't believe I'm doing anything wrong code-wise. My question is: Is there any way for a SIGALRM to be handled in the same thread as a waiting socket_select()? If so, how? If not, what are my alternatives here? Here's some output from my program. My alarm function simply outputs "Tick!" whenever it's called to make it easy to tell when stuff is happening. This is the output (including errors) after allowing it to tick 4 times (there were no actual attempts at connecting to the server despite what it says): [05-28-10 @ 20:01:05] Chat server started on 192.168.1.28 port 4050 [05-28-10 @ 20:01:05] Loaded 2 users from file PHP Notice: Undefined offset: 0 in /home/danny/projects/PHPChatServ/ChatServ.php on line 112 PHP Warning: socket_select(): unable to select [4]: Interrupted system call in /home/danny/projects/PHPChatServ/ChatServ.php on line 116 [05-28-10 @ 20:01:15] Tick!

  • IDataServiceMetadataProvider - Entities dont show up in $metadata.

    - by TomTom
    I am trying to write our own RIA services provider to expose data from a server that I access via ODBC. I follow th eguidelines set out at http://blogs.msdn.com/alexj/archive/2010/03/02/creating-a-data-service-provider-part-9-un-typed.aspx I have written our own IDataServiceMetadataProvider / IDataServiceQueryProvider pair and get no errors on what i do. I am putting in a resource set like this: ResourceType tableType = new ResourceType( typeof(Dictionary<string, object>), ResourceTypeKind.EntityType, null, "Martini", table_name, false ); tableType.CanReflectOnInstanceType = false; var prodKey = new ResourceProperty( "Key", ResourcePropertyKind.Key | ResourcePropertyKind.Primitive, ResourceType.GetPrimitiveResourceType(typeof(int)) ); prodKey.CanReflectOnInstanceTypeProperty = false; tableType.AddProperty(prodKey); var prodName = new ResourceProperty( "Name", ResourcePropertyKind.Primitive, ResourceType.GetPrimitiveResourceType(typeof(string)) ); prodName.CanReflectOnInstanceTypeProperty = false; tableType.AddProperty(prodName); _MetaDataProvider.AddResourceType(tableType); _MetaDataProvider.AddResourceSet(new ResourceSet(table_name, tableType)); I see the requests coming in for enumerating the resource sets. I check them there in a breakpoint, and the resource set and the type is there, with all properties. Still, the output I get is: <?xml version="1.0" encoding="utf-8" standalone="yes" ?> - <service xml:base="http://localhost:2377/MartiniData.svc/" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:app="http://www.w3.org/2007/app" xmlns="http://www.w3.org/2007/app"> - <workspace> <atom:title>Default</atom:title> </workspace> </service> And for the $metadata version: <?xml version="1.0" encoding="utf-8" standalone="yes" ?> - <edmx:Edmx Version="1.0" xmlns:edmx="http://schemas.microsoft.com/ado/2007/06/edmx"> - <edmx:DataServices xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" m:DataServiceVersion="1.0"> - <Schema Namespace="Martini" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns="http://schemas.microsoft.com/ado/2007/05/edm"> <EntityContainer Name="Martini" m:IsDefaultEntityContainer="true" /> </Schema> </edmx:DataServices> </edmx:Edmx> The actual metadata for the types never shows up, no error is shown. pretty frustrating. Anyone any idea?

  • Does weak typing offer any advantages?

    - by sub
    Don't confuse this with static vs. dynamic typing! You all know JavaScripts/PHPs infamous type systems: PHP example: echo "123abc"+2; // 125 - the reason for this is explained // in the PHP docs but still: This hurts echo "4"+1; // 5 - Oh please echo "ABC"*5; // 0 - WTF // That's too much, seriously now. // This here might be actually a use for weak typing, but no - // it has to output garbage. JavaScript example: // A good old JavaScript, maybe you'll do better? alert("4"+1); // 51 - Oh come on. alert("abc"*3); // NaN - What the... // Have your creators ever heard of the word "consistence"? Python example: # Python's type system is actually a mix # It spits errors on senseless things like the first example below AND # allows intelligent actions like the second example. >>> print("abc"+1) Traceback (most recent call last): File "<pyshell#2>", line 1, in <module> print("abc"+1) TypeError: Can't convert 'int' object to str implicitly >>> print("abc"*5) abcabcabcabcabc Ruby example: puts 4+"1" // Type error - as supposed puts "abc"*4 // abcabcabcabc - makes sense After these examples it should be clear that PHP/JavaScript probably have the most inconsistent type systems out there. This is a fact and really not subjective. Now when having a closer look at the type systems of Ruby and Python it seems like they are having a much more intelligent and consistent type system. I think these examples weren't really necessary as we all know that PHP/JavaScript have a weak and Python/Ruby have a strong type system. I just wanted to mention why I'm asking this. Now I have two questions: When looking at those examples, what are the advantages of PHPs and JavaScripts type systems? I can only find downsides: They are inconsistent and I think we know that this is not good Types conversions are hardly controllable Bugs are more likely to happen and much harder to spot Do you prefer one of the both systems? Why? Personally I have worked with PHP, JavaScript and Python so far and must say that Pythons type system has really only advantages over PHPs and JavaScripts. Does anybody here not think so? Why then?

  • Crawling not working windows2008

    - by axtolf
    Hi, We installed a new MOSS 2007 farm on windows 2008 SP2 enviroment. We used SQL2008 too. Configuration is 1 index, 1 FE and 1 server with 2008, all on ESX 4.0. All the Service that need it uses a dedicated user, so search has a dedicated user. Installation went well and we found no problem. We installed an SP1 MOSS from a ISO and after we upgraded WSS and MOSS to SP2. We installed the Italian language pack too and patched it to SP2. We created a new SSP. We created a web application and created a root website under it. The problem is that we can't male crawling work in any way. Seems that crawling is not able to reach the web application that we want to crawl. In event viewer of the index we have this error when we try to crawl it: The start address <h..p://name.domain.it:81 cannot be crawled. Context: Application 'SSP1', Catalog 'Portal_Content' Details: The object was not found. (0x80041201) The log of crawling from the search admin, only says: h..p://name.domani.it:81 The object was not found. (The item was deleted because it was either not found or the crawler was denied access to it.) The domain is fully accessible from everywhere using both farm admin user or the search user that we are using for service to run. Site is fully accessible from the index and seem not have problem. Inside the we application we created a root site collection with a couple of file. The log of the farm simply says.... nothing! When we ask to do a full crawl of the site, it runs for a second and after we have the errors that I wrote above. But the farm's log says nothing. Any suggestion or help is really appreciated since we are losing a lot of time on it and really we do not have any idea of what's wrong about this farm.

  • C# searching for new Tool for the tool box, how to template this code

    - by Nix
    All i have something i have been trying to do for a while and have yet to find a good strategy to do it, i am not sure C# can even support what i am trying to do. Example imagine a template like this, repeated in manager code overarching cocept function Returns a result consisting of a success flag and error list. public Result<Boolean> RemoveLocation(LocationKey key) { List<Error> errorList = new List<Error>(); Boolean result = null; try{ result = locationDAO.RemoveLocation(key); }catch(UpdateException ue){ //Error happened less pass this back to the user! errorList = ue.ErrorList; } return new Result<Boolean>(result, errorList); } Looking to turn it into a template like the below where Do Something is some call (preferably not static) that returns a Boolean. I know i could do this in a stack sense, but i am really looking for a way to do it via object reference. public Result<Boolean> RemoveLocation(LocationKey key) { var magic = locationDAO.RemoveLocation(key); return ProtectedDAOCall(magic); } public Result<Boolean> CreateLocation(LocationKey key) { var magic = locationDAO.CreateLocation(key); return ProtectedDAOCall(magic); } public Result<Boolean> ProtectedDAOCall(Func<..., bool> doSomething) { List<Error> errorList = new List<Error>(); Boolean result = null; try{ result = doSomething(); }catch(UpdateException ue){ //Error happened less pass this back to the user! errorList = ue.ErrorList; } return new Result<Boolean>(result, errorList); } If there is any more information you may need let me know. I am interested to see what someone else can come up with. Marc solution applied to the code above public Result<Boolean> CreateLocation(LocationKey key) { LocationDAO locationDAO = new LocationDAO(); return WrapMethod(() => locationDAO.CreateLocation(key)); } public Result<Boolean> RemoveLocation(LocationKey key) { LocationDAO locationDAO = new LocationDAO(); return WrapMethod(() => locationDAO.RemoveLocation(key)); } static Result<T> WrapMethod<T>(Func<Result<T>> func) { try { return func(); } catch (UpdateException ue) { return new Result<T>(default(T), ue.Errors); } }
