Subject:MySQL Connector/Net 1.0.9 is now available
View as plain text  

MySQL Connector/Net 1.0.9 has been released. MySQL Connector/Net is an 
all-managed ADO.Net provider for MySQL. This release is suitable for use in 
production environments and with any version of MySQL.

It is now available in source and binary form from the Connector/Net 
download pages at and 
mirror sites (note that not all mirror sites may be up to date at this point 
of time - if you can't find this version on some mirror, please try again 
later or choose another download site.)

This release includes many bug fixes along with the following 

* Implemented a stored procedure cache. By default, the connector caches the 
metadata for the last 25    procedures that are seen. You can change the 
number of procedures that are cached by using the 'procedure cache=<size>' 
connection string setting. You can disable the procedure cache by setting a 
zero size.

* Shared memory connections now work as expected.

* Queries containing a large number of parameters now run many times faster 
than before. As an example of the performance gains seen, an internal 
testing app that needed more than 30 minutes to execute using 1.0.7, 
completes in less than 8 seconds using 1.0.9.

* We are no longer providing binaries compiled with .NET 1.0 or 2.0 with 
this branch of the connector. We are doing this for a couple of reasons. 
First, we believe the vast majority of our users are using .NET 1.1 or 2.0 
so not shipping 1.0 binaries reduces our testing workload while affecting a 
small number of developers.  Also, any user building applications with .NET 
Framework 2.0 should use our new 5.0 product which fully implements the 
ADO.Net interfaces.

* ICSharpCode ZipLib is no longer used by the connector and is no longer 
being distributed with it.

* The installer will continue registering the assembly into the Global 
Assembly Cache.  Any user that does not want this behavior is encouraged to 
download our no-installer packages.

* Turned MySqlPoolManager into a static class and added a static constructor 
to avoid any race conditions related to initializing the hash table.

* Added 'Ignore Prepare' connection string option for disabling prepared 
statements application-wide.  This was added because we found that 
server-side prepared statements did not always work as expected.  Using this 
option, a user can continue to use existing code that calls Prepare() while 
having that call emulated in a non-prepared way.  The default for this 
option is true.

* A nicer exception is displayed if you have added a parameter without the 
parameter marker.

* Improved CommandBuilder.DeriveParameters to first try and use the 
procedure cache before querying for the stored procedure metadata.

* Return parameters created with DeriveParameters now have the name 

* Fixed problem with parameter name hashing where the hashes were not 
getting updated when parameters were removed from the collection.  This 
could cause "item has already been added to the hash" errors.

* Fixed problem where pooled connections that are added back to the idle 
pool may be still in the closed state.

* Fixed problem where SingleRow and SchemaOnly behaviors now work correctly 
when calling stored procedures or using server-side prepared statements.

Thank you for checking out this release of Connector/Net.
