invalid transaction handle with aborted threads
-----------------------------------------------
Key: DNET-910
URL: http://tracker.firebirdsql.org/browse/DNET-910
Project: .NET Data provider
Issue Type: Bug
Components: ADO.NET Provider
Affects Versions: 7.1.1.0
Environment: Firebird 2.5.9, .net 4.5.2
Reporter: Christian Mayer
Assignee: Jiri Cincura
Attachments: FirebirdInvalidTransactionHandle.zip
We get this exception in a multithreaded environment with the use of thread abortion.
FirebirdSql.Data.FirebirdClient.FbException (0x80004005): invalid transaction handle (expecting explicit transaction start) ---> invalid transaction handle (expecting explicit transaction start)
bei FirebirdSql.Data.FirebirdClient.FbTransaction.Dispose(Boolean disposing)
bei System.Data.Common.DbTransaction.Dispose()
bei FirebirdSql.Data.FirebirdClient.FbCommand.RollbackImplicitTransaction()
bei FirebirdSql.Data.FirebirdClient.FbCommand.CommitImplicitTransaction()
bei FirebirdSql.Data.FirebirdClient.FbCommand.ExecuteScalar()
It seems that the unfinished implicit transaction is carried to the next connection through connection pooling.
The remaining connection in the thread pool is unusable then.
