SQLite事务与自增深度分析

SQLite什么都好，就怕“database is locked”这些年来想尽办法去规避它。

测试代码：

static void Test2()
{
    XCode.Setting.Current.TransactionDebug = true;

    XTrace.WriteLine(Role.Meta.Count + "");
    XTrace.WriteLine(Log.Meta.Count + "");
    Console.Clear();

    Task.Run(() => TestTask(1));
    Thread.Sleep(1000);
    Task.Run(() => TestTask(2));
}

static void TestTask(Int32 tid)
{
    try
    {
        XTrace.WriteLine("TestTask {0} Start", tid);
        using (var tran = Role.Meta.CreateTrans())
        {
            var role = new Role();
            role.Name = "R" + DateTime.Now.Millisecond;
            role.Save();
            XTrace.WriteLine("role.ID={0}", role.ID);

            Thread.Sleep(3000);

            role = new Role();
            role.Name = "R" + DateTime.Now.Millisecond;
            role.Save();
            XTrace.WriteLine("role.ID={0}", role.ID);

            Thread.Sleep(3000);

            if (tid == 2) tran.Commit();
        }
    }
    catch (Exception ex)
    {
        XTrace.WriteException(ex);
    }
    finally
    {
        XTrace.WriteLine("TestTask {0} End", tid);
    }
}
