[Firebird-net-provider] [FB-Tracker] Created: (DNET-582) Random bug in finalizing DbCommands
Random bug in finalizing DbCommands
---
Key: DNET-582
URL: http://tracker.firebirdsql.org/browse/DNET-582
Project: .NET Data provider
Issue Type: Bug
Components: ADO.NET Provider
Affects Versions: 4.5.2.0
Environment: Windows Server 2008 R2. firebird 2.5.3 x64 embedded
Reporter: Hennadii
Assignee: Jiri Cincura
Several times I've experienced randomly reproduced bug. It has some different
symptoms: OOM, unhandled crash and so on.
But all this times I had the same stack:
1b56edb0 773a186a [FaultingExceptionFrame: 1b56edb0]
1b56f300 07fe9a9920b0
FirebirdSql.Data.FirebirdClient.FbCommand.Release()
[*\FirebirdSql.Data.FirebirdClient\FirebirdClient\FbCommand.cs @ 821]
1b56f340 07fe9a9a47f5
FirebirdSql.Data.FirebirdClient.FbCommand.Dispose(Boolean)
[*\FirebirdSql.Data.FirebirdClient\FirebirdClient\FbCommand.cs @ 384]
1b56f3a0 07fef71cc8da System.ComponentModel.Component.Finalize()
1b56f798 07fef9479d56 [DebuggerU2MCatchHandlerFrame:
1b56f798]
It is locally built library so I'll provide lines referred above:
FbCommand.cs @ 821
if (this.connection != null this.connection.State ==
ConnectionState.Open)
{
this.connection.InnerConnection.RemovePreparedCommand(this);
}
FbCommand.cs @ 384
try
{
// Release any unmanaged resources
this.Release();
I've added crutch to the FbCommand.Release method as in other places, just
handle exception without any code. But I think it is not the best way to fix it.
try
{
// old code
}
catch // added
{
}
finally
{
base.Dispose(disposing);
}
Don't you think that catching swallowing exceptions in dispose methods is a bad
way to handle errors?

I'm trying to add support for Firebird db for existing app on SQL Express, and, first run of the application was with no errors and created the database. I'll going to try migrations steps and give feedback. Thanks Jiri Paul MERCEA ___ E-mail: paul.mer...@almexa.ro ___ -- Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
