.NET provider should explicitly call fb_shutdown() on application exit when
using Firebird Embedded
---------------------------------------------------------------------------------------------------
Key: DNET-806
URL: http://tracker.firebirdsql.org/browse/DNET-806
Project: .NET Data provider
Issue Type: Bug
Components: ADO.NET Provider
Affects Versions: 5.12.1.0
Reporter: Mark Rotteveel
Assignee: Jiri Cincura
If the apllication exits and there are still connections open using Firebird
Embedded, then the exit may produce an access violation (0xc0000005 error). The
root cause is that the fbembed.dll/fbclient.dll will call fb_shutdown() itself,
but one of the other libraries (eg fbintl.dll) may already have been unloaded.
To prevent this, on exit the .NET provider should explicitly call fb_shutdown
for any of the native libries loaded (but especially for embedded).
See also "Crash Firebird 2.5.8 Embedded with Firebird Ado.net provider." on
Firebird-devel.
Related: DNET-802 (cleaning up the connection pool on exit will also prevent
the access violation).
