linq

I am trying to implement retry logic for Aws Aurora Mysql.

In Linq2db there is retyrpolicy already implemented except there is no way to pass retrypolicy to DataContext.

public class RetryingDataContext : DataContext
{
protected IRetryPolicy _retryPolicy;
public RetryingDataContext(IDataProvider dataProvider, string c

The .forall pattern is a great way to create an optional filter for a field that could be defined or not:

case class Person(name: String, age: Int)
val nameOpt: Option[String] = Some("Joe")
run { query[Person].filter(p => lift(nameOpt).forall(_ == p.name)) }
// SELECT p.name, p.age FROM Person p WHERE ? IS NULL OR ? = p.name
// (i.e. when nameOpt := None then the `WHERE ? IS NULL`

SessionFactoryImpl.Close currently allows the body of the function to be run multiple times as it does not check if it is closed prior to proceeding. This should be changed so that Close when called from Dispose does nothing when Close has been called by the application.

On a general level I am not an expert in NHibernate or FluentNHibernate. I need your help to collect all the improvements and bugs that have been lost in the past and are relevant, and the following NHibernate improvements.
