POWhy is NHibernate AdoTransaction's finalizer called?
text
Body
copied!<p>I'm profiling out unit & integration tests, and I find the a lot of the time is spent on the finalizer of NHibernate.Transaction.AdoTransaction - this means it is not getting disposed properly.</p> <p>I am not using AdoTransaction directly in the code, so it's probably used by some other object inside NHibernate. Any idea what I'm forgetting to Dispose?</p> <p>Here is my text fixture:</p> <pre><code>public abstract class AbstractInMemoryFixture { protected ISessionFactory sessionFactory; protected ILogger Logger { get; private set; } static readonly Configuration config; private static readonly ISessionFactory internalSessionFactory; static AbstractInMemoryFixture() { config = new NHibernateConfigurator().Configure(NHibernateConfigurators.SQLiteInMemory()); internalSessionFactory = config.BuildSessionFactory(); } [SetUp] public void SetUp() { const string sqliteInMemoryConnectionString = "Data Source=:memory:;Version=3;Pooling=False;Max Pool Size=1;"; var con = new SQLiteConnection(sqliteInMemoryConnectionString); con.Open(); new SchemaExport(config).Execute(false, true, false, true, con, System.Console.Out); var proxyGenerator = new ProxyGenerator(); sessionFactory = proxyGenerator.CreateInterfaceProxyWithTarget(internalSessionFactory, new UseExistingConnectionInterceptor(con)); Logger = new NullLogger(); ExtraSetup(); } [TearDown] public void TearDown() { var con = sessionFactory.OpenSession().Connection; if (con != null) { if (con.State == ConnectionState.Open) con.Close(); con.Dispose(); } } private class UseExistingConnectionInterceptor :IInterceptor { private readonly SQLiteConnection connection; public UseExistingConnectionInterceptor(SQLiteConnection connection) { this.connection = connection; } public void Intercept(IInvocation invocation) { if (invocation.Method.Name != "OpenSession" || invocation.Method.GetParameters().Length > 0) { invocation.Proceed(); return; } var factory = (ISessionFactory) invocation.InvocationTarget; invocation.ReturnValue = factory.OpenSession(connection); } } protected virtual void ExtraSetup() { } } </code></pre>
