Not providing DataSource to connection now causes error
-------------------------------------------------------
Key: DNET-912
URL: http://tracker.firebirdsql.org/browse/DNET-912
Project: .NET Data provider
Issue Type: Bug
Components: ADO.NET Provider
Affects Versions: 7.1.0.0
Environment: Windows 10
Reporter: Greg Cobb
Assignee: Jiri Cincura
Priority: Minor
I have some code that broke after updating to 7.1.1 from 6.5. I have a
program, a custom installer application we wrote, that is only ever run on the
same computer where Firebird is installed. Previously because the application
already had verified that it was being run on the server, I didn't bother to
specify that the DataSource property on FbConnectionStringBuilder should be set
to localhost. After updating to 7.1.1, this lack of providing the DataSource
explicitly broke our application. I am sorry, but I have not reverted back to
6.5 to prove whether the FbConnectionStringBuilder is the one forgetting to
specify that the DataSource should be localhost by default or whether it is
instead the FbConnection class that can no longer handle not being provided a
DataSource.
Error Message:
An invalid connection string argument has been supplied or a required
connection string argument has not been supplied.
It is my opinion that this probably should be something where you probably want
to keep applications that did not provide the DataSource from breaking when
they update to the latest ADO.NET driver. I know that in most scenarios you
will want to provide a DataSource, but localhost seems to have been the default
up until now and that is probably a pretty safe bet if one was not provided.
