Changes in MySQL Connector/Net 6.3.6 (2011-01-03)

This release fixes bugs since 6.3.5.

Functionality Added or Changed

  • Changed how the procedure schema collection is retrieved. If the connection string contains use procedure bodies=true then a SELECT is performed on the mysql.proc table directly, as this is up to 50 times faster than the current Information Schema implementation. If the connection string contains use procedure bodies=false, then the Information Schema collection is queried. (Bug #36694)

Bugs Fixed

  • MembershipProvider did not generate hashes correctly if the algorithm was keyed. The Key of the algorithm should have been set if the HashAlgorithm was KeyedHashAlgorithm. (Bug #58906)

  • Code introduced to fix bug #54863 proved problematic on .NET version 3.5 and above. (Bug #58853)

  • The MySqlTokenizer contained unnecessary Substring and Trim calls:

    string token = sql.Substring(startIndex, stopIndex - startIndex).Trim();

    The variable token was not used anywhere in the code. (Bug #58757)

  • MySqlCommand.ExecuteReader(CommandBehavior) threw a NullReferenceException when being called with CommandBehavior.CloseConnection, if the SQL statement contained a syntax error, or contained invalid data such as an invalid column name. (Bug #58652)

  • ReadFieldLength() returned incorrect value for BIGINT autoincrement columns. (Bug #58373)

  • When attempting to create an ADO.NET Entity Data Model, MySQL connections were not available. (Bug #58278)

  • MySQL Connector/Net did not support the utf8mb4 character set. When attempting to connect to utf8mb4 tables or columns, an exception KeyNotFoundException was generated. (Bug #58244)

  • Installation of MySQL Connector/Net 6.3.5 failed. The error reported was:

    MySQL Connector Net 6.3.5 Setup Wizard ended 
    prematurely because of an error. Your system has not been modified.

    (Bug #57654)

  • When the tracing driver was used and an SQL statement was longer than 300 characters, an ArgumentOutOfRangeExcpetion occurred if the statement also contained a quoted character, and the 300th character was in the middle of a quoted token. (Bug #57641)

  • Calling the Read() method on a DataReader obtained from MySqlHelper.ExecuteReader generated the following exception:

    Unhandled Exception: MySql.Data.MySqlClient.MySqlException: Invalid attempt to R
    ead when reader is closed.
       at MySql.Data.MySqlClient.MySqlDataReader.Read()
       at MySqlTest.MainClass.Main(String[] args)

    (Bug #57501)

  • Default values returned for text columns were not quoted. This meant that the COLUMN_DEFAULT field of the GetSchema columns collection did not return a valid SQL expression. (Bug #56509)

  • When using MySQL Connector/Net on Mono 2.8 using .NET 4.0, attempting to connect to a MySQL database generated the following exception:

    Unhandled Exception: System.MissingMethodException: Method not found:
      at (wrapper remoting-invoke-with-check)
     MySql.Data.MySqlClient.MySqlConnection:Open ()

    (Bug #56509)

  • MySQL Connector/Net for .NET/Mono attempted to dynamically load the assembly Mono.Posix.dll when a Unix socket was used to connect to the server. This failed and the connector was not able to use a Unix socket unless the Mono.Posix.dll assembly was previously loaded by the program. (Bug #56410)

  • The ADO.NET Entity Data Model could not add stored procedures from MySQL Server 5.0.45 but worked fine using MySQL Server 5.1. (Bug #55349)

  • In the ADO.NET Entity Data Model Wizard, the time to update a model scaled abnormally as the number of entities increased. (Bug #48791, Bug #12596237)
