• Hibernate mapping one-to-many problem

  - by Xorty

  Hello, I am not very experienced with Hibernate and I am trying to create one-to-many mapping. Here are relevant tables: And here are my mapping files: <hibernate-mapping package="com.xorty.mailclient.server.domain"> <class name="Attachment" table="Attachment"> <id name="id"> <column name="idAttachment"></column> </id> <property name="filename"> <column name="name"></column> </property> <property name="blob"> <column name="file"></column> <type name="blob"></type> </property> <property name="mailId"> <column name="mail_idmail"></column> </property> </class> </hibernate-mapping> <hibernate-mapping> <class name="com.xorty.mailclient.server.domain.Mail" table="mail"> <id name="id" type="integer" column="idmail"></id> <property name="content"> <column name="body"></column> </property> <property name="ownerAddress"> <column name="account_address"></column> </property> <property name="title"> <column name="head"></column> </property> <set name="receivers" table="mail_has_contact" cascade="all"> <key column="mail_idmail"></key> <many-to-many column="contact_address" class="com.xorty.mailclient.client.domain.Contact"></many-to-many> </set> <list name="attachments" cascade="save-update, delete" inverse="true"> <key column="mail_idmail" not-null="true"/> <index column="fk_Attachment_mail1"></index> <one-to-many class="com.xorty.mailclient.server.domain.Attachment"/> </list> </class> </hibernate-mapping> In plain english, one mail has more attachments. When I try to do CRUD on mail without attachments, everyting works just fine. When I add some attachment to mail, I cannot perform any CRUD operation. I end up with following trace: org.hibernate.exception.ConstraintViolationException: Could not execute JDBC batch update at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:96) at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:66) at org.hibernate.jdbc.AbstractBatcher.executeBatch(AbstractBatcher.java:275) at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:268) at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:184) at org.hibernate.event.def.AbstractFlushingEventListener.performExecutions(AbstractFlushingEventListener.java:321) at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:51) at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:1216) at org.hibernate.impl.SessionImpl.managedFlush(SessionImpl.java:383) at org.hibernate.transaction.JDBCTransaction.commit(JDBCTransaction.java:133) at domain.DatabaseTest.testPersistMailWithAttachment(DatabaseTest.java:355) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at junit.framework.TestCase.runTest(TestCase.java:168) at junit.framework.TestCase.runBare(TestCase.java:134) at junit.framework.TestResult$1.protect(TestResult.java:110) at junit.framework.TestResult.runProtected(TestResult.java:128) at junit.framework.TestResult.run(TestResult.java:113) at junit.framework.TestCase.run(TestCase.java:124) at junit.framework.TestSuite.runTest(TestSuite.java:232) at junit.framework.TestSuite.run(TestSuite.java:227) at org.junit.internal.runners.JUnit38ClassRunner.run(JUnit38ClassRunner.java:83) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:49) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) Caused by: java.sql.BatchUpdateException: Cannot add or update a child row: a foreign key constraint fails (`maildb`.`attachment`, CONSTRAINT `fk_Attachment_mail1` FOREIGN KEY (`mail_idmail`) REFERENCES `mail` (`idmail`) ON DELETE NO ACTION ON UPDATE NO ACTION) at com.mysql.jdbc.PreparedStatement.executeBatchSerially(PreparedStatement.java:1666) at com.mysql.jdbc.PreparedStatement.executeBatch(PreparedStatement.java:1082) at org.hibernate.jdbc.BatchingBatcher.doExecuteBatch(BatchingBatcher.java:70) at org.hibernate.jdbc.AbstractBatcher.executeBatch(AbstractBatcher.java:268) ... 27 more Thank you

• What are good design practices when working with Entity Framework

  - by AD

  This will apply mostly for an asp.net application where the data is not accessed via soa. Meaning that you get access to the objects loaded from the framework, not Transfer Objects, although some recommendation still apply. This is a community post, so please add to it as you see fit. Applies to: Entity Framework 1.0 shipped with Visual Studio 2008 sp1. Why pick EF in the first place? Considering it is a young technology with plenty of problems (see below), it may be a hard sell to get on the EF bandwagon for your project. However, it is the technology Microsoft is pushing (at the expense of Linq2Sql, which is a subset of EF). In addition, you may not be satisfied with NHibernate or other solutions out there. Whatever the reasons, there are people out there (including me) working with EF and life is not bad.make you think. EF and inheritance The first big subject is inheritance. EF does support mapping for inherited classes that are persisted in 2 ways: table per class and table the hierarchy. The modeling is easy and there are no programming issues with that part. (The following applies to table per class model as I don't have experience with table per hierarchy, which is, anyway, limited.) The real problem comes when you are trying to run queries that include one or many objects that are part of an inheritance tree: the generated sql is incredibly awful, takes a long time to get parsed by the EF and takes a long time to execute as well. This is a real show stopper. Enough that EF should probably not be used with inheritance or as little as possible. Here is an example of how bad it was. My EF model had ~30 classes, ~10 of which were part of an inheritance tree. On running a query to get one item from the Base class, something as simple as Base.Get(id), the generated SQL was over 50,000 characters. Then when you are trying to return some Associations, it degenerates even more, going as far as throwing SQL exceptions about not being able to query more than 256 tables at once. Ok, this is bad, EF concept is to allow you to create your object structure without (or with as little as possible) consideration on the actual database implementation of your table. It completely fails at this. So, recommendations? Avoid inheritance if you can, the performance will be so much better. Use it sparingly where you have to. In my opinion, this makes EF a glorified sql-generation tool for querying, but there are still advantages to using it. And ways to implement mechanism that are similar to inheritance. Bypassing inheritance with Interfaces First thing to know with trying to get some kind of inheritance going with EF is that you cannot assign a non-EF-modeled class a base class. Don't even try it, it will get overwritten by the modeler. So what to do? You can use interfaces to enforce that classes implement some functionality. For example here is a IEntity interface that allow you to define Associations between EF entities where you don't know at design time what the type of the entity would be. public enum EntityTypes{ Unknown = -1, Dog = 0, Cat } public interface IEntity { int EntityID { get; } string Name { get; } Type EntityType { get; } } public partial class Dog : IEntity { // implement EntityID and Name which could actually be fields // from your EF model Type EntityType{ get{ return EntityTypes.Dog; } } } Using this IEntity, you can then work with undefined associations in other classes // lets take a class that you defined in your model. // that class has a mapping to the columns: PetID, PetType public partial class Person { public IEntity GetPet() { return IEntityController.Get(PetID,PetType); } } which makes use of some extension functions: public class IEntityController { static public IEntity Get(int id, EntityTypes type) { switch (type) { case EntityTypes.Dog: return Dog.Get(id); case EntityTypes.Cat: return Cat.Get(id); default: throw new Exception("Invalid EntityType"); } } } Not as neat as having plain inheritance, particularly considering you have to store the PetType in an extra database field, but considering the performance gains, I would not look back. It also cannot model one-to-many, many-to-many relationship, but with creative uses of 'Union' it could be made to work. Finally, it creates the side effet of loading data in a property/function of the object, which you need to be careful about. Using a clear naming convention like GetXYZ() helps in that regards. Compiled Queries Entity Framework performance is not as good as direct database access with ADO (obviously) or Linq2SQL. There are ways to improve it however, one of which is compiling your queries. The performance of a compiled query is similar to Linq2Sql. What is a compiled query? It is simply a query for which you tell the framework to keep the parsed tree in memory so it doesn't need to be regenerated the next time you run it. So the next run, you will save the time it takes to parse the tree. Do not discount that as it is a very costly operation that gets even worse with more complex queries. There are 2 ways to compile a query: creating an ObjectQuery with EntitySQL and using CompiledQuery.Compile() function. (Note that by using an EntityDataSource in your page, you will in fact be using ObjectQuery with EntitySQL, so that gets compiled and cached). An aside here in case you don't know what EntitySQL is. It is a string-based way of writing queries against the EF. Here is an example: "select value dog from Entities.DogSet as dog where dog.ID = @ID". The syntax is pretty similar to SQL syntax. You can also do pretty complex object manipulation, which is well explained [here][1]. Ok, so here is how to do it using ObjectQuery< string query = "select value dog " + "from Entities.DogSet as dog " + "where dog.ID = @ID"; ObjectQuery<Dog> oQuery = new ObjectQuery<Dog>(query, EntityContext.Instance)); oQuery.Parameters.Add(new ObjectParameter("ID", id)); oQuery.EnablePlanCaching = true; return oQuery.FirstOrDefault(); The first time you run this query, the framework will generate the expression tree and keep it in memory. So the next time it gets executed, you will save on that costly step. In that example EnablePlanCaching = true, which is unnecessary since that is the default option. The other way to compile a query for later use is the CompiledQuery.Compile method. This uses a delegate: static readonly Func<Entities, int, Dog> query_GetDog = CompiledQuery.Compile<Entities, int, Dog>((ctx, id) => ctx.DogSet.FirstOrDefault(it => it.ID == id)); or using linq static readonly Func<Entities, int, Dog> query_GetDog = CompiledQuery.Compile<Entities, int, Dog>((ctx, id) => (from dog in ctx.DogSet where dog.ID == id select dog).FirstOrDefault()); to call the query: query_GetDog.Invoke( YourContext, id ); The advantage of CompiledQuery is that the syntax of your query is checked at compile time, where as EntitySQL is not. However, there are other consideration... Includes Lets say you want to have the data for the dog owner to be returned by the query to avoid making 2 calls to the database. Easy to do, right? EntitySQL string query = "select value dog " + "from Entities.DogSet as dog " + "where dog.ID = @ID"; ObjectQuery<Dog> oQuery = new ObjectQuery<Dog>(query, EntityContext.Instance)).Include("Owner"); oQuery.Parameters.Add(new ObjectParameter("ID", id)); oQuery.EnablePlanCaching = true; return oQuery.FirstOrDefault(); CompiledQuery static readonly Func<Entities, int, Dog> query_GetDog = CompiledQuery.Compile<Entities, int, Dog>((ctx, id) => (from dog in ctx.DogSet.Include("Owner") where dog.ID == id select dog).FirstOrDefault()); Now, what if you want to have the Include parametrized? What I mean is that you want to have a single Get() function that is called from different pages that care about different relationships for the dog. One cares about the Owner, another about his FavoriteFood, another about his FavotireToy and so on. Basicly, you want to tell the query which associations to load. It is easy to do with EntitySQL public Dog Get(int id, string include) { string query = "select value dog " + "from Entities.DogSet as dog " + "where dog.ID = @ID"; ObjectQuery<Dog> oQuery = new ObjectQuery<Dog>(query, EntityContext.Instance)) .IncludeMany(include); oQuery.Parameters.Add(new ObjectParameter("ID", id)); oQuery.EnablePlanCaching = true; return oQuery.FirstOrDefault(); } The include simply uses the passed string. Easy enough. Note that it is possible to improve on the Include(string) function (that accepts only a single path) with an IncludeMany(string) that will let you pass a string of comma-separated associations to load. Look further in the extension section for this function. If we try to do it with CompiledQuery however, we run into numerous problems: The obvious static readonly Func<Entities, int, string, Dog> query_GetDog = CompiledQuery.Compile<Entities, int, string, Dog>((ctx, id, include) => (from dog in ctx.DogSet.Include(include) where dog.ID == id select dog).FirstOrDefault()); will choke when called with: query_GetDog.Invoke( YourContext, id, "Owner,FavoriteFood" ); Because, as mentionned above, Include() only wants to see a single path in the string and here we are giving it 2: "Owner" and "FavoriteFood" (which is not to be confused with "Owner.FavoriteFood"!). Then, let's use IncludeMany(), which is an extension function static readonly Func<Entities, int, string, Dog> query_GetDog = CompiledQuery.Compile<Entities, int, string, Dog>((ctx, id, include) => (from dog in ctx.DogSet.IncludeMany(include) where dog.ID == id select dog).FirstOrDefault()); Wrong again, this time it is because the EF cannot parse IncludeMany because it is not part of the functions that is recognizes: it is an extension. Ok, so you want to pass an arbitrary number of paths to your function and Includes() only takes a single one. What to do? You could decide that you will never ever need more than, say 20 Includes, and pass each separated strings in a struct to CompiledQuery. But now the query looks like this: from dog in ctx.DogSet.Include(include1).Include(include2).Include(include3) .Include(include4).Include(include5).Include(include6) .[...].Include(include19).Include(include20) where dog.ID == id select dog which is awful as well. Ok, then, but wait a minute. Can't we return an ObjectQuery< with CompiledQuery? Then set the includes on that? Well, that what I would have thought so as well: static readonly Func<Entities, int, ObjectQuery<Dog>> query_GetDog = CompiledQuery.Compile<Entities, int, string, ObjectQuery<Dog>>((ctx, id) => (ObjectQuery<Dog>)(from dog in ctx.DogSet where dog.ID == id select dog)); public Dog GetDog( int id, string include ) { ObjectQuery<Dog> oQuery = query_GetDog(id); oQuery = oQuery.IncludeMany(include); return oQuery.FirstOrDefault; } That should have worked, except that when you call IncludeMany (or Include, Where, OrderBy...) you invalidate the cached compiled query because it is an entirely new one now! So, the expression tree needs to be reparsed and you get that performance hit again. So what is the solution? You simply cannot use CompiledQueries with parametrized Includes. Use EntitySQL instead. This doesn't mean that there aren't uses for CompiledQueries. It is great for localized queries that will always be called in the same context. Ideally CompiledQuery should always be used because the syntax is checked at compile time, but due to limitation, that's not possible. An example of use would be: you may want to have a page that queries which two dogs have the same favorite food, which is a bit narrow for a BusinessLayer function, so you put it in your page and know exactly what type of includes are required. Passing more than 3 parameters to a CompiledQuery Func is limited to 5 parameters, of which the last one is the return type and the first one is your Entities object from the model. So that leaves you with 3 parameters. A pitance, but it can be improved on very easily. public struct MyParams { public string param1; public int param2; public DateTime param3; } static readonly Func<Entities, MyParams, IEnumerable<Dog>> query_GetDog = CompiledQuery.Compile<Entities, MyParams, IEnumerable<Dog>>((ctx, myParams) => from dog in ctx.DogSet where dog.Age == myParams.param2 && dog.Name == myParams.param1 and dog.BirthDate > myParams.param3 select dog); public List<Dog> GetSomeDogs( int age, string Name, DateTime birthDate ) { MyParams myParams = new MyParams(); myParams.param1 = name; myParams.param2 = age; myParams.param3 = birthDate; return query_GetDog(YourContext,myParams).ToList(); } Return Types (this does not apply to EntitySQL queries as they aren't compiled at the same time during execution as the CompiledQuery method) Working with Linq, you usually don't force the execution of the query until the very last moment, in case some other functions downstream wants to change the query in some way: static readonly Func<Entities, int, string, IEnumerable<Dog>> query_GetDog = CompiledQuery.Compile<Entities, int, string, IEnumerable<Dog>>((ctx, age, name) => from dog in ctx.DogSet where dog.Age == age && dog.Name == name select dog); public IEnumerable<Dog> GetSomeDogs( int age, string name ) { return query_GetDog(YourContext,age,name); } public void DataBindStuff() { IEnumerable<Dog> dogs = GetSomeDogs(4,"Bud"); // but I want the dogs ordered by BirthDate gridView.DataSource = dogs.OrderBy( it => it.BirthDate ); } What is going to happen here? By still playing with the original ObjectQuery (that is the actual return type of the Linq statement, which implements IEnumerable), it will invalidate the compiled query and be force to re-parse. So, the rule of thumb is to return a List< of objects instead. static readonly Func<Entities, int, string, IEnumerable<Dog>> query_GetDog = CompiledQuery.Compile<Entities, int, string, IEnumerable<Dog>>((ctx, age, name) => from dog in ctx.DogSet where dog.Age == age && dog.Name == name select dog); public List<Dog> GetSomeDogs( int age, string name ) { return query_GetDog(YourContext,age,name).ToList(); //<== change here } public void DataBindStuff() { List<Dog> dogs = GetSomeDogs(4,"Bud"); // but I want the dogs ordered by BirthDate gridView.DataSource = dogs.OrderBy( it => it.BirthDate ); } When you call ToList(), the query gets executed as per the compiled query and then, later, the OrderBy is executed against the objects in memory. It may be a little bit slower, but I'm not even sure. One sure thing is that you have no worries about mis-handling the ObjectQuery and invalidating the compiled query plan. Once again, that is not a blanket statement. ToList() is a defensive programming trick, but if you have a valid reason not to use ToList(), go ahead. There are many cases in which you would want to refine the query before executing it. Performance What is the performance impact of compiling a query? It can actually be fairly large. A rule of thumb is that compiling and caching the query for reuse takes at least double the time of simply executing it without caching. For complex queries (read inherirante), I have seen upwards to 10 seconds. So, the first time a pre-compiled query gets called, you get a performance hit. After that first hit, performance is noticeably better than the same non-pre-compiled query. Practically the same as Linq2Sql When you load a page with pre-compiled queries the first time you will get a hit. It will load in maybe 5-15 seconds (obviously more than one pre-compiled queries will end up being called), while subsequent loads will take less than 300ms. Dramatic difference, and it is up to you to decide if it is ok for your first user to take a hit or you want a script to call your pages to force a compilation of the queries. Can this query be cached? { Dog dog = from dog in YourContext.DogSet where dog.ID == id select dog; } No, ad-hoc Linq queries are not cached and you will incur the cost of generating the tree every single time you call it. Parametrized Queries Most search capabilities involve heavily parametrized queries. There are even libraries available that will let you build a parametrized query out of lamba expressions. The problem is that you cannot use pre-compiled queries with those. One way around that is to map out all the possible criteria in the query and flag which one you want to use: public struct MyParams { public string name; public bool checkName; public int age; public bool checkAge; } static readonly Func<Entities, MyParams, IEnumerable<Dog>> query_GetDog = CompiledQuery.Compile<Entities, MyParams, IEnumerable<Dog>>((ctx, myParams) => from dog in ctx.DogSet where (myParams.checkAge == true && dog.Age == myParams.age) && (myParams.checkName == true && dog.Name == myParams.name ) select dog); protected List<Dog> GetSomeDogs() { MyParams myParams = new MyParams(); myParams.name = "Bud"; myParams.checkName = true; myParams.age = 0; myParams.checkAge = false; return query_GetDog(YourContext,myParams).ToList(); } The advantage here is that you get all the benifits of a pre-compiled quert. The disadvantages are that you most likely will end up with a where clause that is pretty difficult to maintain, that you will incur a bigger penalty for pre-compiling the query and that each query you run is not as efficient as it could be (particularly with joins thrown in). Another way is to build an EntitySQL query piece by piece, like we all did with SQL. protected List<Dod> GetSomeDogs( string name, int age) { string query = "select value dog from Entities.DogSet where 1 = 1 "; if( !String.IsNullOrEmpty(name) ) query = query + " and dog.Name == @Name "; if( age > 0 ) query = query + " and dog.Age == @Age "; ObjectQuery<Dog> oQuery = new ObjectQuery<Dog>( query, YourContext ); if( !String.IsNullOrEmpty(name) ) oQuery.Parameters.Add( new ObjectParameter( "Name", name ) ); if( age > 0 ) oQuery.Parameters.Add( new ObjectParameter( "Age", age ) ); return oQuery.ToList(); } Here the problems are: - there is no syntax checking during compilation - each different combination of parameters generate a different query which will need to be pre-compiled when it is first run. In this case, there are only 4 different possible queries (no params, age-only, name-only and both params), but you can see that there can be way more with a normal world search. - Noone likes to concatenate strings! Another option is to query a large subset of the data and then narrow it down in memory. This is particularly useful if you are working with a definite subset of the data, like all the dogs in a city. You know there are a lot but you also know there aren't that many... so your CityDog search page can load all the dogs for the city in memory, which is a single pre-compiled query and then refine the results protected List<Dod> GetSomeDogs( string name, int age, string city) { string query = "select value dog from Entities.DogSet where dog.Owner.Address.City == @City "; ObjectQuery<Dog> oQuery = new ObjectQuery<Dog>( query, YourContext ); oQuery.Parameters.Add( new ObjectParameter( "City", city ) ); List<Dog> dogs = oQuery.ToList(); if( !String.IsNullOrEmpty(name) ) dogs = dogs.Where( it => it.Name == name ); if( age > 0 ) dogs = dogs.Where( it => it.Age == age ); return dogs; } It is particularly useful when you start displaying all the data then allow for filtering. Problems: - Could lead to serious data transfer if you are not careful about your subset. - You can only filter on the data that you returned. It means that if you don't return the Dog.Owner association, you will not be able to filter on the Dog.Owner.Name So what is the best solution? There isn't any. You need to pick the solution that works best for you and your problem: - Use lambda-based query building when you don't care about pre-compiling your queries. - Use fully-defined pre-compiled Linq query when your object structure is not too complex. - Use EntitySQL/string concatenation when the structure could be complex and when the possible number of different resulting queries are small (which means fewer pre-compilation hits). - Use in-memory filtering when you are working with a smallish subset of the data or when you had to fetch all of the data on the data at first anyway (if the performance is fine with all the data, then filtering in memory will not cause any time to be spent in the db). Singleton access The best way to deal with your context and entities accross all your pages is to use the singleton pattern: public sealed class YourContext { private const string instanceKey = "On3GoModelKey"; YourContext(){} public static YourEntities Instance { get { HttpContext context = HttpContext.Current; if( context == null ) return Nested.instance; if (context.Items[instanceKey] == null) { On3GoEntities entity = new On3GoEntities(); context.Items[instanceKey] = entity; } return (YourEntities)context.Items[instanceKey]; } } class Nested { // Explicit static constructor to tell C# compiler // not to mark type as beforefieldinit static Nested() { } internal static readonly YourEntities instance = new YourEntities(); } } NoTracking, is it worth it? When executing a query, you can tell the framework to track the objects it will return or not. What does it mean? With tracking enabled (the default option), the framework will track what is going on with the object (has it been modified? Created? Deleted?) and will also link objects together, when further queries are made from the database, which is what is of interest here. For example, lets assume that Dog with ID == 2 has an owner which ID == 10. Dog dog = (from dog in YourContext.DogSet where dog.ID == 2 select dog).FirstOrDefault(); //dog.OwnerReference.IsLoaded == false; Person owner = (from o in YourContext.PersonSet where o.ID == 10 select dog).FirstOrDefault(); //dog.OwnerReference.IsLoaded == true; If we were to do the same with no tracking, the result would be different. ObjectQuery<Dog> oDogQuery = (ObjectQuery<Dog>) (from dog in YourContext.DogSet where dog.ID == 2 select dog); oDogQuery.MergeOption = MergeOption.NoTracking; Dog dog = oDogQuery.FirstOrDefault(); //dog.OwnerReference.IsLoaded == false; ObjectQuery<Person> oPersonQuery = (ObjectQuery<Person>) (from o in YourContext.PersonSet where o.ID == 10 select o); oPersonQuery.MergeOption = MergeOption.NoTracking; Owner owner = oPersonQuery.FirstOrDefault(); //dog.OwnerReference.IsLoaded == false; Tracking is very useful and in a perfect world without performance issue, it would always be on. But in this world, there is a price for it, in terms of performance. So, should you use NoTracking to speed things up? It depends on what you are planning to use the data for. Is there any chance that the data your query with NoTracking can be used to make update/insert/delete in the database? If so, don't use NoTracking because associations are not tracked and will causes exceptions to be thrown. In a page where there are absolutly no updates to the database, you can use NoTracking. Mixing tracking and NoTracking is possible, but it requires you to be extra careful with updates/inserts/deletes. The problem is that if you mix then you risk having the framework trying to Attach() a NoTracking object to the context where another copy of the same object exist with tracking on. Basicly, what I am saying is that Dog dog1 = (from dog in YourContext.DogSet where dog.ID == 2).FirstOrDefault(); ObjectQuery<Dog> oDogQuery = (ObjectQuery<Dog>) (from dog in YourContext.DogSet where dog.ID == 2 select dog); oDogQuery.MergeOption = MergeOption.NoTracking; Dog dog2 = oDogQuery.FirstOrDefault(); dog1 and dog2 are 2 different objects, one tracked and one not. Using the detached object in an update/insert will force an Attach() that will say "Wait a minute, I do already have an object here with the same database key. Fail". And when you Attach() one object, all of its hierarchy gets attached as well, causing problems everywhere. Be extra careful. How much faster is it with NoTracking It depends on the queries. Some are much more succeptible to tracking than other. I don't have a fast an easy rule for it, but it helps. So I should use NoTracking everywhere then? Not exactly. There are some advantages to tracking object. The first one is that the object is cached, so subsequent call for that object will not hit the database. That cache is only valid for the lifetime of the YourEntities object, which, if you use the singleton code above, is the same as the page lifetime. One page request == one YourEntity object. So for multiple calls for the same object, it will load only once per page request. (Other caching mechanism could extend that). What happens when you are using NoTracking and try to load the same object multiple times? The database will be queried each time, so there is an impact there. How often do/should you call for the same object during a single page request? As little as possible of course, but it does happens. Also remember the piece above about having the associations connected automatically for your? You don't have that with NoTracking, so if you load your data in multiple batches, you will not have a link to between them: ObjectQuery<Dog> oDogQuery = (ObjectQuery<Dog>)(from dog in YourContext.DogSet select dog); oDogQuery.MergeOption = MergeOption.NoTracking; List<Dog> dogs = oDogQuery.ToList(); ObjectQuery<Person> oPersonQuery = (ObjectQuery<Person>)(from o in YourContext.PersonSet select o); oPersonQuery.MergeOption = MergeOption.NoTracking; List<Person> owners = oPersonQuery.ToList(); In this case, no dog will have its .Owner property set. Some things to keep in mind when you are trying to optimize the performance. No lazy loading, what am I to do? This can be seen as a blessing in disguise. Of course it is annoying to load everything manually. However, it decreases the number of calls to the db and forces you to think about when you should load data. The more you can load in one database call the better. That was always true, but it is enforced now with this 'feature' of EF. Of course, you can call if( !ObjectReference.IsLoaded ) ObjectReference.Load(); if you want to, but a better practice is to force the framework to load the objects you know you will need in one shot. This is where the discussion about parametrized Includes begins to make sense. Lets say you have you Dog object public class Dog { public Dog Get(int id) { return YourContext.DogSet.FirstOrDefault(it => it.ID == id ); } } This is the type of function you work with all the time. It gets called from all over the place and once you have that Dog object, you will do very different things to it in different functions. First, it should be pre-compiled, because you will call that very often. Second, each different pages will want to have access to a different subset of the Dog data. Some will want the Owner, some the FavoriteToy, etc. Of course, you could call Load() for each reference you need anytime you need one. But that will generate a call to the database each time. Bad idea. So instead, each page will ask for the data it wants to see when it first request for the Dog object: static public Dog Get(int id) { return GetDog(entity,"");} static public Dog Get(int id, string includePath) { string query = "select value o " + " from YourEntities.DogSet as o " +

• Uploadify Minimum Image Width And Height

  So I am using the Uplodify plugin to allow users to upload multiple images at once. The problem is I need to set a minimum width and height for images. Let's say 150x150px is the smallest image users can upload. How can I set this limitation in the Uploadify plugin? When user tries to upload smaller picture, I would like to display some error message as well. Here is the PHP file that is called bu the plugin to upload images: <?php define('BASE_PATH', substr(dirname(dirname(__FILE__)), 0, -22)); // set the include path set_include_path(BASE_PATH . '/../library' . PATH_SEPARATOR . BASE_PATH . '/library' . PATH_SEPARATOR . get_include_path()); // autoload classes from the library function __autoload($class) { include str_replace('_', '/', $class) . '.php'; } $configuration = new Zend_Config_Ini(BASE_PATH . '/application' . '/configs/application.ini', 'development'); $dbAdapter = Zend_Db::factory($configuration->database); Zend_Db_Table_Abstract::setDefaultAdapter($dbAdapter); function _getTable($table) { include BASE_PATH . '/application/modules/default/models/' . $table . '.php'; return new $table(); } $albums = _getTable('Albums'); $media = _getTable('Media'); if (false === empty($_FILES)) { $tempFile = $_FILES['Filedata']['tmp_name']; $extension = end(explode('.', $_FILES['Filedata']['name'])); // insert temporary row into the database $data = array(); $data['type'] = 'photo'; $data['type2'] = 'public'; $data['status'] = 'temporary'; $data['user_id'] = $_REQUEST['user_id']; $paths = $media->add($data, $extension, $dbAdapter); // save the photo move_uploaded_file($tempFile, BASE_PATH . '/public/' . $paths[0]); // create a thumbnail include BASE_PATH . '/library/My/PHPThumbnailer/ThumbLib.inc.php'; $thumb = PhpThumbFactory::create(BASE_PATH . '/public/' . $paths[0]); $thumb->adaptiveResize(85, 85); $thumb->save(BASE_PATH . '/public/' . $paths[1]); // add watermark to the bottom right corner $pathToFullImage = BASE_PATH . '/public/' . $paths[0]; $size = getimagesize($pathToFullImage); switch ($extension) { case 'gif': $im = imagecreatefromgif($pathToFullImage); break; case 'jpg': $im = imagecreatefromjpeg($pathToFullImage); break; case 'png': $im = imagecreatefrompng($pathToFullImage); break; } if (false !== $im) { $white = imagecolorallocate($im, 255, 255, 255); $font = BASE_PATH . '/public/fonts/arial.ttf'; imagefttext($im, 13, // font size 0, // angle $size[0] - 132, // x axis (top left is [0, 0]) $size[1] - 13, // y axis $white, $font, 'HunnyHive.com'); switch ($extension) { case 'gif': imagegif($im, $pathToFullImage); break; case 'jpg': imagejpeg($im, $pathToFullImage, 100); break; case 'png': imagepng($im, $pathToFullImage, 0); break; } imagedestroy($im); } echo "1"; } And here's the javascript: $(document).ready(function() { $('#photo').uploadify({ 'uploader' : '/flash-uploader/scripts/uploadify.swf', 'script' : '/flash-uploader/scripts/upload-public-photo.php', 'cancelImg' : '/flash-uploader/cancel.png', 'scriptData' : {'user_id' : 'USER_ID'}, 'queueID' : 'fileQueue', 'auto' : true, 'multi' : true, 'sizeLimit' : 2097152, 'fileExt' : '*.jpg;*.jpeg;*.gif;*.png', 'wmode' : 'transparent', 'onComplete' : function() { $.get('/my-account/temporary-public-photos', function(data) { $('#temporaryPhotos').html(data); }); } }); $('#upload_public_photo').hover(function() { var titles = '{'; $('.title').each(function() { var title = $(this).val(); if ('Title...' != title) { var id = $(this).attr('name'); id = id.substr(5); title = jQuery.trim(title); if (titles.length > 1) { titles += ','; } titles += '"' + id + '"' + ':"' + title + '"'; } }); titles += '}'; $('#titles').val(titles); }); }); Now bear in mind that I know how to check images dimensions in the PHP file. But I'm not sure how to modify the javascript so it won't upload images with very small dimensions.

• PayPal IPN - having trouble accessing session data?

  - by Martin Bean

  Hello, all. I'm having issues with PayPal IPN integration where it seems I cannot get my solution to read session variables. Basically, in my shop module script, I store the customer's details as provided by PayPal to an orders table. However, I also wish to save products ordered in a transaction to a separate table linked by the order ID. However, it's the second part of the script that's not working, where I loop through the products in the session and then save them to the orders_products table. Is there a reason why the session data not being read? The code within shop.php is as follows: if ($paypal->validate_ipn()) { $name = $paypal->ipn_data['address_name']; $street_1 = $paypal->ipn_data['address_street']; $street_2 = ""; $city = $paypal->ipn_data['address_city']; $state = $paypal->ipn_data['address_state']; $zip = $paypal->ipn_data['address_zip']; $country = $paypal->ipn_data['address_country']; $txn_id = $paypal->ipn_data['txn_id']; $sql = "INSERT INTO orders (name, street_1, street_2, city, state, zip, country, txn_id) VALUES (:name, :street_1, :street_2, :city, :state, :zip, :country, :txn_id)"; $smt = $this->pdo->prepare($sql); $smt->bindParam(':name', $name, PDO::PARAM_STR); $smt->bindParam(':street_1', $street_1, PDO::PARAM_STR); $smt->bindParam(':street_2', $street_2, PDO::PARAM_STR); $smt->bindParam(':city', $city, PDO::PARAM_STR); $smt->bindParam(':state', $state, PDO::PARAM_STR); $smt->bindParam(':zip', $zip, PDO::PARAM_STR); $smt->bindParam(':country', $country, PDO::PARAM_STR); $smt->bindParam(':txn_id', $txn_id, PDO::PARAM_INT); $smt->execute(); // save products to orders relationship $order_id = $this->pdo->lastInsertId(); // $cart = $this->session->get('cart'); $cart = $this->session->get('cart'); foreach ($cart as $product_id => $item) { $quantity = $item['quantity']; $sql = "INSERT INTO orders_products (order_id, product_id, quantity) VALUES ('$order_id', '$product_id', '$quantity')"; $res = $this->pdo->query($sql); } $this->session->del('cart'); mail('[email protected]', 'IPN result', 'IPN was successful on wrestling-wear.com'); } else { mail('[email protected]', 'IPN result', 'IPN failed on wrestling-wear.com'); } And I'm using the PayPal IPN class for PHP as found here: http://www.micahcarrick.com/04-19-2005/php-paypal-ipn-integration-class.html, but the contents of the validate_ipn() method is as follows: public function validate_ipn() { $url_parsed = parse_url($this->paypal_url); $post_string = ''; foreach ($_POST as $field => $value) { $this->ipn_data[$field] = $value; $post_string.= $field.'='.urlencode(stripslashes($value)).'&'; } $post_string.= "cmd=_notify-validate"; // append IPN command // open the connection to PayPal $fp = fsockopen($url_parsed[host], "80", $err_num, $err_str, 30); if (!$fp) { // could not open the connection. If logging is on, the error message will be in the log $this->last_error = "fsockopen error no. $errnum: $errstr"; $this->log_ipn_results(false); return false; } else { // post the data back to PayPal fputs($fp, "POST $url_parsed[path] HTTP/1.1\r\n"); fputs($fp, "Host: $url_parsed[host]\r\n"); fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n"); fputs($fp, "Content-length: ".strlen($post_string)."\r\n"); fputs($fp, "Connection: close\r\n\r\n"); fputs($fp, $post_string . "\r\n\r\n"); // loop through the response from the server and append to variable while (!feof($fp)) { $this->ipn_response.= fgets($fp, 1024); } fclose($fp); // close connection } if (eregi("VERIFIED", $this->ipn_response)) { // valid IPN transaction $this->log_ipn_results(true); return true; } else { // invalid IPN transaction; check the log for details $this->last_error = 'IPN Validation Failed.'; $this->log_ipn_results(false); return false; } }

• Namespaced Backbone.js Views not firing events

  - by Stasio

  I'm currently getting started with Backbone.js. I've wrote some examples with Backbone and they are working fine. But now I need to use Backbone.js with Rails 3.1 and CoffeeScript. I took my well-working examples and rewrote on CoffeeScript using backbone-rails gem. And got the following problem. I've simplyfied code, but the problem is still remaining I've got the following files: Here I'm starting my Backbone app at main.js.coffee file according to my main_controller in rails app: $ = jQuery $-> CsfTaskManager.init() Here is backbone app description: #= require_self #= require_tree ./templates #= require_tree ./models #= require_tree ./views #= require_tree ./routers window.CsfTaskManager = Models: {} Collections: {} Routers: {} Views: {} init: -> new CsfTaskManager.Routers.AppRouter() Backbone.history.start() This is my apps' router: class CsfTaskManager.Routers.AppRouter extends Backbone.Router initialize: (options) -> goalsBlock = new CsfTaskManager.Views.goalsView() routes: "!/": "root", some other routes... And finally view: class CsfTaskManager.Views.goalsView extends Backbone.View initialize: -> this.goals = new CsfTaskManager.Collections.GoalsCollection() el: $('div#app'), events: "click .add-btn": "addGoal" addGoal: -> alert('ji') HTML page has such code: <div id="app"> <div class="app-screen hidden" id="goal-form" style="display: block; "> <button class="btn" id="load"> Load </button> <h3> New Goal </h3> <div class="form-stacked"> <form accept-charset="UTF-8" action="/goals" class="new_goal" id="new_goal" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="?"><input name="authenticity_token" type="hidden" value="Pnt+V/tS1/b079M/1ZIRdw2ss1D6bvJKVh868DXRjUg="></div> <label for="goal_title">Title</label> <p></p> <input class="goal-title" id="goal_title" name="goal[title]" size="30" type="text"> <p></p> <label for="goal_note">Note</label> <p></p> <input class="goal-note" id="goal_note" name="goal[note]" size="30" type="text"> </form> </div> <p> <button class="add-btn btn"> Add </button> </p> <ul id="goals-list"></ul> </div> <table class="app-screen bordered-table" id="calendar-grid" style="display: none; "> <tbody><tr> <td colspan="2"> week </td> </tr> <tr> <td> day </td> <td> <div id="calendar"></div> </td> </tr> </tbody></table> <div class="app-screen hidden" id="role-form" style="display: none; "> <h3> New User Role </h3> <div class="form-stacked"> <form accept-charset="UTF-8" action="/roles" class="new_role" id="new_role" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="?"><input name="authenticity_token" type="hidden" value="Pnt+V/tS1/b079M/1ZIRdw2ss1D6bvJKVh868DXRjUg="></div> <label for="role_title">Title</label> <p></p> <input class="role-title" id="role_name" name="role[name]" size="30" type="text"> <p></p> <label for="role_note">Note</label> <p></p> <input class="role-note" id="role_description" name="role[description]" size="30" type="text"> </form> </div> <p> <button class="add-btn btn"> Add </button> </p> </div> </div> So .add-btn element is nested in #app, but click on this button doesn't fire event. Where can be a trouble? Before, when I had the same app in one .js file, without of coffeescript, namespacing and backbone-rails gem, everything was allright. Bytheway, appRouter works fine, goalsView object is created successfully too, but events don't fire for some reasons. Please give me some hint, because I'm really got stuck...

• GWT Query fails second time -only.

  - by Koran

  HI, I have a visualization function in GWT which calls for two instances of the same panels - two queries. Now, suppose one url is A and the other url is B. Here, I am facing an issue in that if A is called first, then both A and B works. If B is called first, then only B works, A - times out. If I call both times A, only the first time A works, second time it times out. If I call B twice, it works both times without a hitch. Even though the error comes at timed out, it actually is not timing out - in FF status bar, it shows till - transferring data from A, and then it gets stuck. This doesnt even show up in the first time query. The only difference between A and B is that B returns very fast, while A returns comparitively slow. The sample code is given below: public Panel(){ Runnable onLoadCallback = new Runnable() { public void run() { Query query = Query.create(dataUrl); query.setTimeout(60); query.send(new Callback() { public void onResponse(QueryResponse response) { if (response.isError()){ Window.alert(response.getMessage()); } } } } VisualizationUtils.loadVisualizationApi(onLoadCallback, PieChart.PACKAGE); } What could be the reason for this? I cannot think of any reason why this should happen? Why is this happening only for A and not for B? EDIT: More research. The query which works all the time (i.e. B is the example URL given in GWT visualization site: see comment [1]). So, I tried in my app engine to reproduce it - the following way s = "google.visualization.Query.setResponse({version:'0.6',status:'ok',sig:'106459472',table:{cols:[{id:'A',label:'Source',type:'string',pattern:''},{id:'B',label:'Percent',type:'number',pattern:'#0.01%'}],rows:[{c:[{v:'Oil'},{v:0.37,f:'37.00%'}]},{c:[{v:'Coal'},{v:0.25,f:'25.00%'}]},{c:[{v:'Natural Gas'},{v:0.23,f:'23.00%'}]},{c:[{v:'Nuclear'},{v:0.06,f:'6.00%'}]},{c:[{v:'Biomass'},{v:0.04,f:'4.00%'}]},{c:[{v:'Hydro'},{v:0.03,f:'3.00%'}]},{c:[{v:'Solar Heat'},{v:0.005,f:'0.50%'}]},{c:[{v:'Wind'},{v:0.003,f:'0.30%'}]},{c:[{v:'Geothermal'},{v:0.002,f:'0.20%'}]},{c:[{v:'Biofuels'},{v:0.002,f:'0.20%'}]},{c:[{v:'Solar photovoltaic'},{v:4.0E-4,f:'0.04%'}]}]}});"; response = HttpResponse(s, content_type="text/plain; charset=utf-8") response['Expires'] = time.strftime('%a, %d %b %Y %H:%M:%S GMT', time.gmtime()) return response Where s is the data when we run the query for B. I tried to add Expires etc too, since that seems to be the only header which has the difference, but now, the query fails all the time. For more info - I am now sending the difference between my server response vs the working server response. They seems to be pretty similar.

• How to refresh DataGrid and DropDown on main page after hiding modal popup

  Hi, I am adding records to a database from a modal popup. After hiding the modal popup, the page has not been refreshed even though I have Rebound the controls. I have reviewed a few postings on the web about this but the solution still evades me. I have attached my code after removing some of the extra detail... It seems I need to cause a postback but I don't know what needs to be changed. Some posts have talked about the extender being misplaced.

• Different ways to query this search in SQL?

  - by Bart Terrell

  I am teaching myself MS-SQL and I am trying to find different ways to find the Count of Paid and Unpaid Claims for 2012 grouped by Region from these 3 tables. If there is a returned date, the claim is unpaid if the returned date is null then the claim is paid. I will attach the code I have ran, but I am not sure if there are better ways to do it. Thanks. Here is the code: SET dateformat ymd; CREATE TABLE Claims ( ClaimID INT, SubID INT, [Claim Date] DATETIME ); CREATE TABLE Phoneship ( ClaimID INT, [Shipping Number] INT, [Claim Date] DATETIME, [Ship Date] DATETIME, [Returned Date] DATETIME );

• Ruby erb template- try to change layout- get error

  - by nigel curruthers

  Hi there! I'm working my way through adapting a template I have been given that is basically a list of products for sale. I want to change it from a top-down list into a table layout. I want to end up with something as follows- <div id= 'ladiesproducts'> <% ladies_products = hosting_products.find_all do |product| product.name.match("ladies") end %> <table><tbody> <% [ladies_products].each do | slice | %> <tr> <% slice.each do | product | %> <td> <h4><%= product.name.html %></h4> <p><%= product.description %></p> <% other parts go here %> </td> <% end %> </tr> <% end %> </tbody></table> </div> This works fine for the layout that I am trying to achieve. The problem I have is when I paste back the <% other parts go here % part of the code. I get an internal error message on the page. I am completely new to Ruby so am just bumbling my way through this really. I have a hunch that I'm neglecting something that is probably very simple. The <% other parts go here %> code is as follows: <input type='hidden' name='base_renewal_period-<%= i %>' value="<%= product.base_renewal_period %>" /> <input type='hidden' name='quoted_unit_price-<%= i %>' value="<%= billing.price(product.unit_price) %>" /> <p><input type='radio' name='add-product' value='<%= product.specific_type.html %>:<%= i %>:base_renewal_period,quoted_unit_price,domain' /><%= billing.currency_symbol.html %><%= billing.price(product.unit_price, :use_tax_prefs) %> <% if product.base_renewal_period != 'never' %> every <%= product.unit_period.to_s_short.html %> <% end %> <% if product.setup_fee != 0 %> plus a one off fee of <%= billing.currency_symbol.html %><%= sprintf("%.2f", if billing.include_tax? then billing.price(product.setup_fee) else product.setup_fee end) %> <% end %> <% if product.has_free_products? %> <br /> includes free domains <% product.free_products_list.each do | free_product | %> <%= free_product["free_name"] %> <% end %> <% end %> * </p> <% i = i + 1 %> <% end %> <p><input type='submit' value='Add to Basket'/></p> </form> <% unless basket.nil? or basket.empty? or no_upsell? %> <p><a href='basket?add-no-product=package'>No thank you, please continue with my order ...</a></p> <% end %> <% if not billing.tax_applies? %> <% elsif billing.include_tax? %> <p>* Includes <%= billing.tax_name %></p> <% else %> <p>* Excluding <%= billing.tax_name %></p> <% end %> If anyone can point out what I'm doing wrong or what I'm missing or failing to change I would GREATLY appreciate it! Many thanks in advance. Nigel

• How to check all check boxes at a click of a button

  - by LivingThing

  I am new to Swing, UI and MVC I have created a code based on MVC. Now my problem is that that in the controller part i have an actioneventlistener which listens to different button clicks. Out of all those buttons i have "select all" and "de-select all". In my view i have a table, one of the column of that table contains "check boxes". Now, when i click the "select-all" button i want to check all the check boxes and with "de-select all" i want to uncheck all of them. Below is my code which is not working. Please tell me what am i doing wrong here. Also, if someone knows a more elagent way please share. Thanks In my view public class CustomerSelectorDialogUI extends JFrame{ public CustomerSelectorDialogUI(TestApplicationUI ownerView, DummyCustomerStore dCStore, boolean modality) { //super(ownerView, modality); setTitle("[=] Customer Selection Dialog [=]"); //setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE); custSelectPanel = new JPanel(); buttonPanel = new JPanel(); selectAllButton = new JButton(" Select All "); clearAllButton = new JButton(" Clear All "); applyButton = new JButton(" Apply "); cancelButton = new JButton(" Cancel "); PopulateAndShow(dCStore, Boolean.FALSE); } public void PopulateAndShow(DummyCustomerStore dCStore, Boolean select) { List data = new ArrayList(); for (Customer customer : dCStore.getAllCustomers()) { Object record[] = new Object[COLUMN_COUNT]; record[0] = (select == false) ?

• NOOB Memory Problem - EXC_BAD_ACCESS

  - by Michael Bordelon

  I have been banging my head against the wall for a couple days and need some help. I have a feeling that I am doing something really silly here, but I cannot find the issue. This is the controller for a table view. I put the SQL in line to simplify it as part of the troubleshooting of this error. Normally, it would be in an accessor method in a model class. It gets through the SQL read just fine. Finds the two objects, loads them into the todaysWorkout array and then builds the cells for the table view. The table view actually comes up on the scree and then it throws the EXC_BAD_ACCESS. I ran instruments and it shows the following: 0 CFString Malloc 1 00:03.765 0x3946470 176 Foundation -[NSPlaceholderString initWithFormat:locale:arguments:] 1 CFString Autorelease 00:03.765 0x3946470 0 Foundation NSRecordAllocationEvent 2 CFString CFRelease 0 00:03.767 0x3946470 0 Bring It -[WorkoutViewController viewDidLoad] 3 CFString Zombie -1 00:03.917 0x3946470 0 Foundation NSPopAutoreleasePool Here is the source code for the controller.

• .NET Code Evolution

  - by Alois Kraus

  Originally posted on: http://geekswithblogs.net/akraus1/archive/2013/07/24/153504.aspxAt my day job I do look at a lot of code written by other people. Most of the code is quite good and some is even a masterpiece. And there is also code which makes you think WTF… oh it was written by me. Hm not so bad after all. There are many excuses reasons for bad code. Most often it is time pressure followed by not enough ambition (who cares) or insufficient training. Normally I do care about code quality quite a lot which makes me a (perceived) slow worker who does write many tests and refines the code quite a lot because of the design deficiencies. Most of the deficiencies I do find by putting my design under stress while checking for invariants. It does also help a lot to step into the code with a debugger (sometimes also Windbg). I do this much more often when my tests are red. That way I do get a much better understanding what my code really does and not what I think it should be doing. This time I do want to show you how code can evolve over the years with different .NET Framework versions. Once there was  time where .NET 1.1 was new and many C++ programmers did switch over to get rid of not initialized pointers and memory leaks. There were also nice new data structures available such as the Hashtable which is fast lookup table with O(1) time complexity. All was good and much code was written since then. At 2005 a new version of the .NET Framework did arrive which did bring many new things like generics and new data structures. The “old” fashioned way of Hashtable were coming to an end and everyone used the new Dictionary<xx,xx> type instead which was type safe and faster because the object to type conversion (aka boxing) was no longer necessary. I think 95% of all Hashtables and dictionaries use string as key. Often it is convenient to ignore casing to make it easy to look up values which the user did enter. An often followed route is to convert the string to upper case before putting it into the Hashtable. Hashtable Table = new Hashtable(); void Add(string key, string value) { Table.Add(key.ToUpper(), value); } This is valid and working code but it has problems. First we can pass to the Hashtable a custom IEqualityComparer to do the string matching case insensitive. Second we can switch over to the now also old Dictionary type to become a little faster and we can keep the the original keys (not upper cased) in the dictionary. Dictionary<string, string> DictTable = new Dictionary<string, string>(StringComparer.OrdinalIgnoreCase); void AddDict(string key, string value) { DictTable.Add(key, value); } Many people do not user the other ctors of Dictionary because they do shy away from the overhead of writing their own comparer. They do not know that .NET has for strings already predefined comparers at hand which you can directly use. Today in the many core area we do use threads all over the place. Sometimes things break in subtle ways but most of the time it is sufficient to place a lock around the offender. Threading has become so mainstream that it may sound weird that in the year 2000 some guy got a huge incentive for the idea to reduce the time to process calibration data from 12 hours to 6 hours by using two threads on a dual core machine. Threading does make it easy to become faster at the expense of correctness. Correct and scalable multithreading can be arbitrarily hard to achieve depending on the problem you are trying to solve. Lets suppose we want to process millions of items with two threads and count the processed items processed by all threads. A typical beginners code might look like this: int Counter; void IJustLearnedToUseThreads() { var t1 = new Thread(ThreadWorkMethod); t1.Start(); var t2 = new Thread(ThreadWorkMethod); t2.Start(); t1.Join(); t2.Join(); if (Counter != 2 * Increments) throw new Exception("Hmm " + Counter + " != " + 2 * Increments); } const int Increments = 10 * 1000 * 1000; void ThreadWorkMethod() { for (int i = 0; i < Increments; i++) { Counter++; } } It does throw an exception with the message e.g. “Hmm 10.222.287 != 20.000.000” and does never finish. The code does fail because the assumption that Counter++ is an atomic operation is wrong. The ++ operator is just a shortcut for Counter = Counter + 1 This does involve reading the counter from a memory location into the CPU, incrementing value on the CPU and writing the new value back to the memory location. When we do look at the generated assembly code we will see only inc dword ptr [ecx+10h] which is only one instruction. Yes it is one instruction but it is not atomic. All modern CPUs have several layers of caches (L1,L2,L3) which try to hide the fact how slow actual main memory accesses are. Since cache is just another word for redundant copy it can happen that one CPU does read a value from main memory into the cache, modifies it and write it back to the main memory. The problem is that at least the L1 cache is not shared between CPUs so it can happen that one CPU does make changes to values which did change in meantime in the main memory. From the exception you can see we did increment the value 20 million times but half of the changes were lost because we did overwrite the already changed value from the other thread. This is a very common case and people do learn to protect their  data with proper locking.   void Intermediate() { var time = Stopwatch.StartNew(); Action acc = ThreadWorkMethod_Intermediate; var ar1 = acc.BeginInvoke(null, null); var ar2 = acc.BeginInvoke(null, null); ar1.AsyncWaitHandle.WaitOne(); ar2.AsyncWaitHandle.WaitOne(); if (Counter != 2 * Increments) throw new Exception(String.Format("Hmm {0:N0} != {1:N0}", Counter, 2 * Increments)); Console.WriteLine("Intermediate did take: {0:F1}s", time.Elapsed.TotalSeconds); } void ThreadWorkMethod_Intermediate() { for (int i = 0; i < Increments; i++) { lock (this) { Counter++; } } } This is better and does use the .NET Threadpool to get rid of manual thread management. It does give the expected result but it can result in deadlocks because you do lock on this. This is in general a bad idea since it can lead to deadlocks when other threads use your class instance as lock object. It is therefore recommended to create a private object as lock object to ensure that nobody else can lock your lock object. When you read more about threading you will read about lock free algorithms. They are nice and can improve performance quite a lot but you need to pay close attention to the CLR memory model. It does make quite weak guarantees in general but it can still work because your CPU architecture does give you more invariants than the CLR memory model. For a simple counter there is an easy lock free alternative present with the Interlocked class in .NET. As a general rule you should not try to write lock free algos since most likely you will fail to get it right on all CPU architectures. void Experienced() { var time = Stopwatch.StartNew(); Task t1 = Task.Factory.StartNew(ThreadWorkMethod_Experienced); Task t2 = Task.Factory.StartNew(ThreadWorkMethod_Experienced); t1.Wait(); t2.Wait(); if (Counter != 2 * Increments) throw new Exception(String.Format("Hmm {0:N0} != {1:N0}", Counter, 2 * Increments)); Console.WriteLine("Experienced did take: {0:F1}s", time.Elapsed.TotalSeconds); } void ThreadWorkMethod_Experienced() { for (int i = 0; i < Increments; i++) { Interlocked.Increment(ref Counter); } } Since time does move forward we do not use threads explicitly anymore but the much nicer Task abstraction which was introduced with .NET 4 at 2010. It is educational to look at the generated assembly code. The Interlocked.Increment method must be called which does wondrous things right? Lets see: lock inc dword ptr [eax] The first thing to note that there is no method call at all. Why? Because the JIT compiler does know very well about CPU intrinsic functions. Atomic operations which do lock the memory bus to prevent other processors to read stale values are such things. Second: This is the same increment call prefixed with a lock instruction. The only reason for the existence of the Interlocked class is that the JIT compiler can compile it to the matching CPU intrinsic functions which can not only increment by one but can also do an add, exchange and a combined compare and exchange operation. But be warned that the correct usage of its methods can be tricky. If you try to be clever and look a the generated IL code and try to reason about its efficiency you will fail. Only the generated machine code counts. Is this the best code we can write? Perhaps. It is nice and clean. But can we make it any faster? Lets see how good we are doing currently. Level Time in s IJustLearnedToUseThreads Flawed Code Intermediate 1,5 (lock) Experienced 0,3 (Interlocked.Increment) Master 0,1 (1,0 for int[2]) That lock free thing is really a nice thing. But if you read more about CPU cache, cache coherency, false sharing you can do even better. int[] Counters = new int[12]; // Cache line size is 64 bytes on my machine with an 8 way associative cache try for yourself e.g. 64 on more modern CPUs void Master() { var time = Stopwatch.StartNew(); Task t1 = Task.Factory.StartNew(ThreadWorkMethod_Master, 0); Task t2 = Task.Factory.StartNew(ThreadWorkMethod_Master, Counters.Length - 1); t1.Wait(); t2.Wait(); Counter = Counters[0] + Counters[Counters.Length - 1]; if (Counter != 2 * Increments) throw new Exception(String.Format("Hmm {0:N0} != {1:N0}", Counter, 2 * Increments)); Console.WriteLine("Master did take: {0:F1}s", time.Elapsed.TotalSeconds); } void ThreadWorkMethod_Master(object number) { int index = (int) number; for (int i = 0; i < Increments; i++) { Counters[index]++; } } The key insight here is to use for each core its own value. But if you simply use simply an integer array of two items, one for each core and add the items at the end you will be much slower than the lock free version (factor 3). Each CPU core has its own cache line size which is something in the range of 16-256 bytes. When you do access a value from one location the CPU does not only fetch one value from main memory but a complete cache line (e.g. 16 bytes). This means that you do not pay for the next 15 bytes when you access them. This can lead to dramatic performance improvements and non obvious code which is faster although it does have many more memory reads than another algorithm. So what have we done here? We have started with correct code but it was lacking knowledge how to use the .NET Base Class Libraries optimally. Then we did try to get fancy and used threads for the first time and failed. Our next try was better but it still had non obvious issues (lock object exposed to the outside). Knowledge has increased further and we have found a lock free version of our counter which is a nice and clean way which is a perfectly valid solution. The last example is only here to show you how you can get most out of threading by paying close attention to your used data structures and CPU cache coherency. Although we are working in a virtual execution environment in a high level language with automatic memory management it does pay off to know the details down to the assembly level. Only if you continue to learn and to dig deeper you can come up with solutions no one else was even considering. I have studied particle physics which does help at the digging deeper part. Have you ever tried to solve Quantum Chromodynamics equations? Compared to that the rest must be easy ;-). Although I am no longer working in the Science field I take pride in discovering non obvious things. This can be a very hard to find bug or a new way to restructure data to make something 10 times faster. Now I need to get some sleep ….

  I'm creating elements (level 1) dynamically which in turn create elements (level 2) themselves. However, the children of level 2 elements have "body" as their parent.

• STORED PROCEDURE working in my local test machine cannot be created in production environment.

  - by Marcos Buarque

  Hi, I have an SQL CREATE PROCEDURE statement that runs perfectly in my local SQL Server, but cannot be recreated in production environment. The error message I get in production is Msg 102, Level 15, State 1, Incorrect syntax near '='. It is a pretty big query and I don't want to annoy StackOverflow users, but I simply can't find a solution. If only you could point me out what settings I could check in the production server in order to enable running the code... I must be using some kind of syntax or something that is conflicting with some setting in production. This PROCEDURE was already registered in production before, but when I ran a DROP - CREATE PROCEDURE today, the server was able to drop the procedure, but not to recreate it.

• EXC_BAD_ACCESS at UITableView on IOS

  - by Suprie

  Hi all, When scrolling through table, my application crash and console said it was EXC_BAD_ACCESS. I've look everywhere, and people suggest me to use NSZombieEnabled on my executables environment variables. I've set NSZombieEnabled, NSDebugEnabled, MallocStackLogging and MallocStackLoggingNoCompact to YES on my executables. But apparently i still can't figure out which part of my program that cause EXC_BAD_ACCESS. This is what my console said [Session started at 2010-12-21 21:11:21 +0700.] GNU gdb 6.3.50-20050815 (Apple version gdb-1510) (Wed Sep 22 02:45:02 UTC 2010) Copyright 2004 Free Software Foundation, Inc.
