Hello All,
I am the first time here to try to find some answers of strange issues I
encountered with firebird provider 2.1.0. Please help.
1. No matter what error happened on database side(I am using embedded firebird
2.0.4), such as a read-only database, the error from the data provider is
always something like below:
11:04:37,099|ERROR|12 |12: Item has already been added. Key in dictionary:
'2062014589' Key being added: '2062014589'System.ArgumentException: Item has
already been added. Key in dictionary: '2062014589' Key being added:
'2062014589' at System.Collections.Hashtable.Insert(Object key, Object
nvalue, Boolean add) at System.Collections.Hashtable.Add(Object key, Object
value) at System.Collections.Hashtable.SyncHashtable.Add(Object key, Object
value) at FirebirdSql.Data.FirebirdClient.FbPoolManager.CreatePool(String
connectionString) at FirebirdSql.Data.FirebirdClient.FbConnection.Open() at
System.Data.Common.DbDataAdapter.FillInternal(DataSet dataset, DataTable[]
datatables, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand
command, CommandBehavior behavior) at
System.Data.Common.DbDataAdapter.Fill(DataTable[] dataTables, Int32
startRecord, Int32 maxRecords, IDbCommand command, CommandBehavior behavior)
at System.Data.Common.DbDataAdapter.Fill(DataTable dataTable)
2. Firebird data provider 2.1.0 cannot support database file created by
firebird server 2.1.0. I debugged provider 2.1.0 to get this information since
the provider always gives above 'Iterm has already been added' error.
3. I tried to use embedded firebird 2.1.0, database file created by 2.0.4 and
firebird provider 2.1.0. After the application UI is closed, the process is
still there and there is only one orphan thread left. Even Environment.Exit()
cannot work. But if I use embedded firebird 2.0.4, the application can exit
properly.
