  • Enum exeeding the 65535 bytes limit of static initializer... what's best to do?

    - by Daniel Bleisteiner
    I've started a rather large Enum of so called Descriptors that I've wanted to use as a reference list in my model. But now I've come across a compiler/VM limit the first time and so I'm looking for the best solution to handle this. Here is my error : The code for the static initializer is exceeding the 65535 bytes limit It is clear where this comes from - my Enum simply has far to much elements. But I need those elements - there is no way to reduce that set. Initialy I've planed to use a single Enum because I want to make sure that all elements within the Enum are unique. It is used in a Hibernate persistence context where the reference to the Enum is stored as String value in the database. So this must be unique! The content of my Enum can be devided into several groups of elements belonging together. But splitting the Enum would remove the unique safety I get during compile time. Or can this be achieved with multiple Enums in some way? My only current idea is to define some Interface called Descriptor and code several Enums implementing it. This way I hope to be able to use the Hibernate Enum mapping as if it were a single Enum. But I'm not even sure if this will work. And I loose unique safety. Any ideas how to handle that case?

  • When would I want to model a class with a private ctor?

    - by dotnetdev
    Hi, I've seen plenty of classes in .NET which have private constructor (Stream is one of them I think). When would I want to model a class like this? I keep thinking that if my class has no internal state/fields, then I can make it have a private constructor. Am I on the right track with this idea? I can understand the use of a factory (I've run into the tipping point a few times), but not with a private constructor class. Thanks

  • CodeContracts: How to fullfill Require in Ctor using this() call?

    - by mafutrct
    I'm playing around with Microsoft's CodeContracts and encountered a problem I was unable to solve. I've got a class with two constructors: public Foo (public float f) { Contracts.Require(f > 0); } public Foo (int i) : this ((float)i) {} The example is simplified. I don't know how to check the second constructor's f for being 0. Is this even possible with Contracts?

  • Gitorious errors

    - by Switz
    I installed Gitorious on my (shared) hosting. I was getting errors, but I seemed to have fixed most of them. It is working. When I commit/push, I get a lot of remote: errors spewed out although it does push the files properly from what I can tell. Here are the errors I'm getting (I swapped out the domain to git.domain.com): $ git push origin master Counting objects: 5, done. Delta compression using up to 2 threads.

  • Subterranean IL: Constructor constraints

    - by Simon Cooper
    The constructor generic constraint is a slightly wierd one. The ECMA specification simply states that it: constrains [the type] to being a concrete reference type (i.e., not abstract) that has a public constructor taking no arguments (the default constructor), or to being a value type. There seems to be no reference within the spec to how you actually create an instance of a generic type with such a constraint. In non-generic methods, the normal way of creating an instance of a class is quite different to initializing an instance of a value type. For a reference type, you use newobj: newobj instance void IncrementableClass::.ctor() and for value types, you need to use initobj: .locals init ( valuetype IncrementableStruct s1 ) ldloca 0 initobj IncrementableStruct But, for a generic method, we need a consistent method that would work equally well for reference or value types. Activator.CreateInstance<T> To solve this problem the CLR designers could have chosen to create something similar to the constrained. prefix; if T is a value type, call initobj, and if it is a reference type, call newobj instance void !!0::.ctor(). However, this solution is much more heavyweight than constrained callvirt. The newobj call is encoded in the assembly using a simple reference to a row in a metadata table. This encoding is no longer valid for a call to !!0::.ctor(), as different constructor methods occupy different rows in the metadata tables. Furthermore, constructors aren't virtual, so we would have to somehow do a dynamic lookup to the correct method at runtime without using a MethodTable, something which is completely new to the CLR. Trying to do this in IL results in the following verification error: newobj instance void !!0::.ctor() [IL]: Error: Unable to resolve token. This is where Activator.CreateInstance<T> comes in. We can call this method to return us a new T, and make the whole issue Somebody Else's Problem. CreateInstance does all the dynamic method lookup for us, and returns us a new instance of the correct reference or value type (strangely enough, Activator.CreateInstance<T> does not itself have a .ctor constraint on its generic parameter): .method private static !!0 CreateInstance<.ctor T>() { call !!0 [mscorlib]System.Activator::CreateInstance<!!0>() ret } Going further: compiler enhancements Although this method works perfectly well for solving the problem, the C# compiler goes one step further. If you decompile the C# version of the CreateInstance method above: private static T CreateInstance() where T : new() { return new T(); } what you actually get is this (edited slightly for space & clarity): .method private static !!T CreateInstance<.ctor T>() { .locals init ( [0] !!T CS$0$0000, [1] !!T CS$0$0001 ) DetectValueType: ldloca.s 0 initobj !!T ldloc.0 box !!T brfalse.s CreateInstance CreateValueType: ldloca.s 1 initobj !!T ldloc.1 ret CreateInstance: call !!0 [mscorlib]System.Activator::CreateInstance<T>() ret } What on earth is going on here? Looking closer, it's actually quite a clever performance optimization around value types. So, lets dissect this code to see what it does. The CreateValueType and CreateInstance sections should be fairly self-explanatory; using initobj for value types, and Activator.CreateInstance for reference types. How does the DetectValueType section work? First, the stack transition for value types: ldloca.s 0 // &[!!T(uninitialized)] initobj !!T // ldloc.0 // !!T box !!T // O[!!T] brfalse.s // branch not taken When the brfalse.s is hit, the top stack entry is a non-null reference to a boxed !!T, so execution continues to to the CreateValueType section. What about when !!T is a reference type? Remember, the 'default' value of an object reference (type O) is zero, or null. ldloca.s 0 // &[!!T(null)] initobj !!T // ldloc.0 // null box !!T // null brfalse.s // branch taken Because box on a reference type is a no-op, the top of the stack at the brfalse.s is null, and so the branch to CreateInstance is taken. For reference types, Activator.CreateInstance is called which does the full dynamic lookup using reflection. For value types, a simple initobj is called, which is far faster, and also eliminates the unboxing that Activator.CreateInstance has to perform for value types. However, this is strictly a performance optimization; Activator.CreateInstance<T> works for value types as well as reference types. Next... That concludes the initial premise of the Subterranean IL series; to cover the details of generic methods and generic code in IL. I've got a few other ideas about where to go next; however, if anyone has any itching questions, suggestions, or things you've always wondered about IL, do let me know.

  • Can a member struct be zero-init from the constructor initializer list without calling memset?

    Let's say I have the following structure declaration (simple struct with no constructor). struct Foo { int x; int y; int z; char szData[DATA_SIZE]; }; Now let's say this struct is a member of a C++ class as follows: class CFoobar { Foo _foo; public: CFoobar(); }; If I declare CFoobar's constructor as follows: CFoobar::CFoobar() { printf("_foo = {%d, %d, %d}\n", _foo.x, _foo.y,_foo.z); for (int x = 0; x < 100; x++) printf("%d\n", _foo.szData[x]); } As you would expect, when CFoobar's constructor runs, garbage data gets printed out Obviously, the easy fix is to memset or ZeroMemory &_foo. It's what I've always done... However, I did notice that if add _foo to the constructor's initialization list with no parameters as follows: CFoobar::CFoobar() : _foo() { That this appears to zero-out the member variables of _foo. At least that was the case with g++ on linux. Now here's my question: Is this standard C++, or is this compiler specific behavior? If it's standard behavior, can someone quote me a reference from an official source? Any "gotchas" in regards to implicit zero-init behavior with more complicated structs and classes?

  • Resgen al.exe generated resources do not work within .net library

    - by Raj G
    Hi, I am currently working on a library in .Net and I planned to make the strings that are used within the library into culture specific resource files. I made Resources.resx, Resources.en-US.resx and Resources.ja-JP.resx file. I also deleted the Resources.designer.cs file autogenerated by visual studio 2008. I am loading Resources through my custom ResourceManager object [using GetString method]. The problem that I am facing is that when I compile the library within visual studio and set the culture from the calling application, everything is working fine. But if I manually go to the directory and change a string for a culture and regenerate the satellite assembly with resgen and al.exe, the string displayed, falls back to the invariant culture. I have attached the ildasm view of both the dlls en-US generated from within visual studio //Metadata version: v2.0.50727 .assembly extern mscorlib { .publickeytoken = (B7 7A 5C 56 19 34 E0 89 ) // .z\V.4.. .hash = (71 05 4D 54 C4 8D C2 90 7D 8B CF 57 2E B5 98 22 // q.MT....}..W..."

  • Configure Cucumber with SentientUser

    - by Corith Malin
    I have an application using the SentientUser gem to provide the current user to my models. On top of that I'm using default scoping to ensure that a user can only ever access data that they own. So a typical model for me looks something like this: class Location < ActiveRecord::Base validates_presence_of :name, :time_zone, :address belongs_to :account belongs_to :address accepts_nested_attributes_for :address default_scope :conditions => { :account_id => User.current.account } end When I run rake cucumber I get an error on the default_scope line about account being nil. My guess is that when the cucumber rake task is run it doesn't have access to the correct application controller to inject the current_user method and thus SentientUser can't get the current user? The error I get is: rake cucumber (in /Users/corithmalin/Documents/Code/Ruby/flavorpulse) /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -I "/Library/Ruby/Gems/1.8/gems/cucumber-0.6.3/lib:lib" "/Library/Ruby/Gems/1.8/gems/cucumber-0.6.3/bin/cucumber" --profile default Using the default profile... undefined method `account' for nil:NilClass (NoMethodError) /Users/corithmalin/Documents/Code/Ruby/flavorpulse/vendor/rails/activesupport/lib/active_support/whiny_nil.rb:52:in `method_missing' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/app/models/location.rb:9 /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `gem_original_require' /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `polyglot_original_require' /Library/Ruby/Gems/1.8/gems/polyglot-0.3.0/lib/polyglot.rb:65:in `require' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/vendor/rails/activesupport/lib/active_support/dependencies.rb:158:in `require' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/vendor/rails/activesupport/lib/active_support/dependencies.rb:265:in `require_or_load' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/vendor/rails/activesupport/lib/active_support/dependencies.rb:224:in `depend_on' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/vendor/rails/activesupport/lib/active_support/dependencies.rb:136:in `require_dependency' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/config/../vendor/rails/railties/lib/initializer.rb:414:in `load_application_classes' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/config/../vendor/rails/railties/lib/initializer.rb:413:in `each' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/config/../vendor/rails/railties/lib/initializer.rb:413:in `load_application_classes' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/config/../vendor/rails/railties/lib/initializer.rb:411:in `each' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/config/../vendor/rails/railties/lib/initializer.rb:411:in `load_application_classes' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/config/../vendor/rails/railties/lib/initializer.rb:197:in `process' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/config/../vendor/rails/railties/lib/initializer.rb:113:in `send' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/config/../vendor/rails/railties/lib/initializer.rb:113:in `run' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/config/environment.rb:9 /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `gem_original_require' /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `polyglot_original_require' /Library/Ruby/Gems/1.8/gems/polyglot-0.3.0/lib/polyglot.rb:65:in `require' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/features/support/env.rb:8 /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `gem_original_require' /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `polyglot_original_require' /Library/Ruby/Gems/1.8/gems/polyglot-0.3.0/lib/polyglot.rb:65:in `require' /Library/Ruby/Gems/1.8/gems/cucumber-0.6.3/bin/../lib/cucumber/rb_support/rb_language.rb:124:in `load_code_file' /Library/Ruby/Gems/1.8/gems/cucumber-0.6.3/bin/../lib/cucumber/step_mother.rb:85:in `load_code_file' /Library/Ruby/Gems/1.8/gems/cucumber-0.6.3/bin/../lib/cucumber/step_mother.rb:77:in `load_code_files' /Library/Ruby/Gems/1.8/gems/cucumber-0.6.3/bin/../lib/cucumber/step_mother.rb:76:in `each' /Library/Ruby/Gems/1.8/gems/cucumber-0.6.3/bin/../lib/cucumber/step_mother.rb:76:in `load_code_files' /Library/Ruby/Gems/1.8/gems/cucumber-0.6.3/bin/../lib/cucumber/cli/main.rb:48:in `execute!' /Library/Ruby/Gems/1.8/gems/cucumber-0.6.3/bin/../lib/cucumber/cli/main.rb:20:in `execute' /Library/Ruby/Gems/1.8/gems/cucumber-0.6.3/bin/cucumber:8 rake aborted!

  • How do I launch a WPF app from command.com. I'm getting a FontCache error.

    - by jttraino
    I know this is not ideal, but my constraint is that I have a legacy application written in Clipper. I want to launch a new, WinForms/WPF application from inside the application (to ease transition). This legacy application written in Clipper launches using: SwpRunCmd("C:\MyApp\MyBat.bat",0) The batch file contains something like this command: C:\PROGRA~1\INTERN~1\iexplore "http://QASVR/MyApp/AppWin/MyCompany.MyApp.AppWin.application#MyCompany.MyApp.AppWin.application" It is launching a WinForms/WPF app that is we deploy via ClickOnce. Everything has been going well until we introduced WPF into the application. We were able to easily launch from the legacy application. Since we have introduced WPF, however, we have the following behavior. If we launch via the Clipper application first, we get an exception when launching the application. The error text is: The type initializer for 'System.Windows.FrameworkElement' threw an exception. at System.Windows.FrameworkElement..ctor() at System.Windows.Controls.Panel..ctor() at System.Windows.Controls.DockPanel..ctor() at System.Windows.Forms.Integration.AvalonAdapter..ctor(ElementHost hostControl) at System.Windows.Forms.Integration.ElementHost..ctor() at MyCompany.MyApp.AppWin.Main.InitializeComponent() at MyCompany.MyApp.AppWin.Main..ctor(String[] args) at MyCompany.MyApp.AppWin.Program.Main(String[] args) The type initializer for 'System.Windows.Documents.TextElement' threw an exception. at System.Windows.FrameworkElement..cctor() The type initializer for 'System.Windows.Media.FontFamily' threw an exception. at System.Windows.Media.FontFamily..ctor(String familyName) at System.Windows.SystemFonts.get_MessageFontFamily() at System.Windows.Documents.TextElement..cctor() The type initializer for 'MS.Internal.FontCache.Util' threw an exception. at MS.Internal.FontCache.Util.get_WindowsFontsUriObject() at System.Windows.Media.FontFamily.PreCreateDefaultFamilyCollection() at System.Windows.Media.FontFamily..cctor() Invalid URI: The format of the URI could not be determined. at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind) at System.Uri..ctor(String uriString, UriKind uriKind) at MS.Internal.FontCache.Util..cctor() If we launch the application via the URL (in IE) or via the icon on the desktop first, we do not get the exception and application launches as expected. The neat thing is that whatever we launch with first determines whether the app will launch at all. So, if we launch with legacy first, it breaks right away and we can't get the app to run even if we launch with the otherwise successful URL or icon. To get it to work, we have to logout and log back in and start it from the URL or icon. If we first use the URL or the icon, we have no problem launching from the legacy application from that point forward (until we logout and come back in). One other piece of information is that we are able to simulate the problem in the following fashion. If we enter a command prompt using "cmd.exe" and execute a statement to launch from a URL, we are successful. If, however, we enter a command prompt using "command.com" and we execute that same statement, we experience the breaking behavior. We assume it is because the legacy application in Clipper uses the equivalent of command.com to create the shell to spawn the other app. We have tried a bunch of hacks like having command.com run cmd.exe or psexec and then executing, but nothing seems to work. We have some ideas for workarounds (like making the app launch on startup so we force the successful launch from a URL, making all subsequent launches successful), but they all are sub-optimal even though we have a great deal of control over our workstations. To reduce the chance that this is related to permissions, we have given the launching account administrative rights (as well as non-administrative rights in case that made a difference). Any ideas would be greatly-appreciate. Like I said, we have some work arounds, but I would love to avoid them. Thanks!

  • readonly keyword

    - by nmarun
    This is something new that I learned about the readonly keyword. Have a look at the following class: 1: public class MyClass 2: { 3: public string Name { get; set; } 4: public int Age { get; set; } 5:  6: private readonly double Delta; 7:  8: public MyClass() 9: { 10: Initializer(); 11: } 12:  13: public MyClass(string name = "", int age = 0) 14: { 15: Name = name; 16: Age = age; 17: Initializer(); 18: } 19:  20: private void Initializer() 21: { 22: Delta = 0.2; 23: } 24: } I have a couple of public properties and a private readonly member. There are two constructors – one that doesn’t take any parameters and the other takes two parameters to initialize the public properties. I’m also calling the Initializer method in both constructors to initialize the readonly member. Now when I build this, the code breaks and the Error window says: “A readonly field cannot be assigned to (except in a constructor or a variable initializer)” Two things after I read this message: It’s such a negative statement. I’d prefer something like: “A readonly field can be assigned to (or initialized) only in a constructor or through a variable initializer” But in my defense, I AM assigning it in a constructor (only indirectly). All I’m doing is creating a method that does it and calling it in a constructor. Turns out, .net was not ‘frameworked’ this way. We need to have the member initialized directly in the constructor. If you have multiple constructors, you can just use the ‘this’ keyword on all except the default constructors to call the default constructor. This default constructor can then initialize your readonly members. This will ensure you’re not repeating the code in multiple places. A snippet of what I’m talking can be seen below: 1: public class Person 2: { 3: public int UniqueNumber { get; set; } 4: public string Name { get; set; } 5: public int Age { get; set; } 6: public DateTime DateOfBirth { get; set; } 7: public string InvoiceNumber { get; set; } 8:  9: private readonly string Alpha; 10: private readonly int Beta; 11: private readonly double Delta; 12: private readonly double Gamma; 13:  14: public Person() 15: { 16: Alpha = "FDSA"; 17: Beta = 2; 18: Delta = 3.0; 19: Gamma = 0.0989; 20: } 21:  22: public Person(int uniqueNumber) : this() 23: { 24: UniqueNumber = uniqueNumber; 25: } 26: } See the syntax in line 22 and you’ll know what I’m talking about. So the default constructor gets called before the one in line 22. These are known as constructor initializers and they allow one constructor to call another. The other ‘myth’ I had about readonly members is that you can set it’s value only once. This was busted as well (I recall Adam and Jamie’s show). Say you’ve initialized the readonly member through a variable initializer. You can over-write this value in any of the constructors any number of times. 1: public class Person 2: { 3: public int UniqueNumber { get; set; } 4: public string Name { get; set; } 5: public int Age { get; set; } 6: public DateTime DateOfBirth { get; set; } 7: public string InvoiceNumber { get; set; } 8:  9: private readonly string Alpha = "asdf"; 10: private readonly int Beta = 15; 11: private readonly double Delta = 0.077; 12: private readonly double Gamma = 1.0; 13:  14: public Person() 15: { 16: Alpha = "FDSA"; 17: Beta = 2; 18: Delta = 3.0; 19: Gamma = 0.0989; 20: } 21:  22: public Person(int uniqueNumber) : this() 23: { 24: UniqueNumber = uniqueNumber; 25: Beta = 3; 26: } 27:  28: public Person(string name, DateTime dob) : this() 29: { 30: Name = name; 31: DateOfBirth = dob; 32:  33: Alpha = ";LKJ"; 34: Gamma = 0.0898; 35: } 36:  37: public Person(int uniqueNumber, string name, int age, DateTime dob, string invoiceNumber) : this() 38: { 39: UniqueNumber = uniqueNumber; 40: Name = name; 41: Age = age; 42: DateOfBirth = dob; 43: InvoiceNumber = invoiceNumber; 44:  45: Alpha = "QWER"; 46: Beta = 5; 47: Delta = 1.0; 48: Gamma = 0.0; 49: } 50: } In the above example, every constructor over-writes the values for the readonly members. This is perfectly valid. There is a possibility that based on the way the object is instantiated, the readonly member will have a different value. Well, that’s all I have for today and read this as it’s on a related topic.

    I've upgraded an ASP.Net Web application to the latest build of Fluent NHibernate (1.0.0.636) and the newest version of NHibernate (v2.1.2.4000).

  • Howto install acts_as_xapian on Ubuntu

    - by normalocity
    I've run into some great resources for installing "acts_as_xapian", and the supporting native libraries that are necessary to make it work. I've even got it to work well on my dev machine (OS X). However, I've followed the instructions on this site, and it doesn't work on my Ubuntu 9.10 (Karmic) production box. After successfully installing the "core" and "bindings" for xapian, the start of the mongrel server fails with the following: => Booting Mongrel => Rails 2.3.5 application starting on http://0.0.0.0:3000 acts_as_xapian: No Ruby bindings for Xapian installed /home/feelgoodtrader/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:105:in `const_missing': uninitialized constant ActsAsXapian::Search::Xapian (NameError) from /var/lib/gems/1.8/gems/acts_as_xapian-0.1.3/lib/acts_as_xapian/search.rb:8 from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `require' from /home/feelgoodtrader/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' from /home/feelgoodtrader/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:521:in `new_constants_in' from /home/feelgoodtrader/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' from /var/lib/gems/1.8/gems/acts_as_xapian-0.1.3/lib/acts_as_xapian.rb:2 from /var/lib/gems/1.8/gems/acts_as_xapian-0.1.3/lib/acts_as_xapian.rb:1:in `each' from /var/lib/gems/1.8/gems/acts_as_xapian-0.1.3/lib/acts_as_xapian.rb:1 from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `require' from /home/feelgoodtrader/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' from /home/feelgoodtrader/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:521:in `new_constants_in' from /home/feelgoodtrader/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' from /home/feelgoodtrader/.gem/ruby/1.8/gems/rails-2.3.5/lib/rails/gem_dependency.rb:208:in `load' from /home/feelgoodtrader/.gem/ruby/1.8/gems/rails-2.3.5/lib/initializer.rb:307:in `load_gems' from /home/feelgoodtrader/.gem/ruby/1.8/gems/rails-2.3.5/lib/initializer.rb:307:in `each' from /home/feelgoodtrader/.gem/ruby/1.8/gems/rails-2.3.5/lib/initializer.rb:307:in `load_gems' from /home/feelgoodtrader/.gem/ruby/1.8/gems/rails-2.3.5/lib/initializer.rb:164:in `process' from /home/feelgoodtrader/.gem/ruby/1.8/gems/rails-2.3.5/lib/initializer.rb:113:in `send' from /home/feelgoodtrader/.gem/ruby/1.8/gems/rails-2.3.5/lib/initializer.rb:113:in `run' from /home/feelgoodtrader/feelgoodtrader/config/environment.rb:13 from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `require' from /home/feelgoodtrader/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' from /home/feelgoodtrader/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:521:in `new_constants_in' from /home/feelgoodtrader/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' from /home/feelgoodtrader/.gem/ruby/1.8/gems/rails-2.3.5/lib/commands/server.rb:84 from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `require' from script/server:3

  • Custom validation works in development but not in unit test

    - by Geolev
    I want to validate that at least one of two columns have a value in my model. I found somewhere on the web that I could create a custom validator as follows: # Check for the presence of one or another field: # :validates_presence_of_at_least_one_field :last_name, :company_name - would require either last_name or company_name to be filled in # also works with arrays # :validates_presence_of_at_least_one_field :email, [:name, :address, :city, :state] - would require email or a mailing type address module ActiveRecord module Validations module ClassMethods def validates_presence_of_at_least_one_field(*attr_names) msg = attr_names.collect {|a| a.is_a?(Array) ? " ( #{a.join(", ")} ) " : a.to_s}.join(", ") + "can't all be blank. At least one field must be filled in." configuration = { :on => :save, :message => msg } configuration.update(attr_names.extract_options!) send(validation_method(configuration[:on]), configuration) do |record| found = false attr_names.each do |a| a = [a] unless a.is_a?(Array) found = true a.each do |attr| value = record.respond_to?(attr.to_s) ? record.send(attr.to_s) : record[attr.to_s] found = !value.blank? end break if found end record.errors.add_to_base(configuration[:message]) unless found end end end end end I put this in a file called lib/acs_validator.rb in my project and added "require 'acs_validator'" to my environment.rb. This does exactly what I want. It works perfectly when I manually test it in the development environment but when I write a unit test it breaks my test environment. This is my unit test: require 'test_helper' class CustomerTest < ActiveSupport::TestCase # Replace this with your real tests. test "the truth" do assert true end test "customer not valid" do puts "customer not valid" customer = Customer.new assert !customer.valid? assert customer.errors.invalid?(:subdomain) assert_equal "Company Name and Last Name can't both be blank.", customer.errors.on(:contact_lname) end end This is my model: class Customer < ActiveRecord::Base validates_presence_of :subdomain validates_presence_of_at_least_one_field :customer_company_name, :contact_lname, :message => "Company Name and Last Name can't both be blank." has_one :service_plan end When I run the unit test, I get the following error: DEPRECATION WARNING: Rake tasks in vendor/plugins/admin_data/tasks, vendor/plugins/admin_data/tasks, and vendor/plugins/admin_data/tasks are deprecated.

Command failed with status (1): [/usr/bin/ruby1.8 -I"lib:test" "/usr/lib/ru...] (See full trace by running task with --trace) It seems to have stepped on will_paginate somehow. Does anyone have any suggestions? Is there another way to do the validation I'm attempting to do? Thanks, George

  • Why do not C++11's move constructor/assignment operator act as expected

    - by xmllmx
    #include <iostream> using namespace std; struct A { A() { cout << "A()" << endl; } ~A() { cout << "~A()" << endl; } A(A&&) { cout << "A(A&&)" << endl; } A& operator =(A&&) { cout << "A& operator =(A&&)" << endl; return *this; } }; struct B { // According to the C++11, the move ctor/assignment operator // should be implicitly declared and defined. The move ctor // /assignment operator should implicitly call class A's move // ctor/assignment operator to move member a. A a; }; B f() { B b; // The compiler knows b is a temporary object, so implicitly // defined move ctor/assignment operator of class B should be // called here. Which will cause A's move ctor is called. return b; } int main() { f(); return 0; } My expected output should be: A() A(A&&) ~A() ~A() However, the actual output is: (The C++ compiler is: Visual Studio 2012) A() ~A() ~A() Is this a bug of VC++? or just my misunderstanding?

  • Constructor invocation returned null: what to do?

    - by strager
    I have code which looks like: private static DirectiveNode CreateInstance(Type nodeType, DirectiveInfo info) { var ctor = nodeType.GetConstructor(new[] { typeof(DirectiveInfo) }); if(ctor == null) { throw new MissingMethodException(nodeType.FullName, "ctor"); } var node = ctor.Invoke(new[] { info }) as DirectiveNode; if(node == null) { // ???; } return node; } I am looking for what to do (e.g. what type of exception to throw) when the Invoke method returns something which isn't a DirectiveNode or when it returns null (indicated by // ??? above). (By the method's contract, nodeType will always describe a subclass of DirectiveNode.) I am not sure when calling a constructor would return null, so I am not sure if I should handle anything at all, but I still want to be on the safe side and throw an exception if something goes wrong.
