PreferredListConnectPolicy always returns preferred controller when the vdb is
unavailable
------------------------------------------------------------------------------------------
Key: SEQUOIA-879
URL: https://forge.continuent.org/jira/browse/SEQUOIA-879
Project: Sequoia
Type: Bug
Components: JDBC Driver
Versions: Sequoia 2.10.3
Reporter: Gilles Rayrat
Assigned to: Gilles Rayrat
Fix For: Sequoia 2.10.4
The following code is buggy:
while (selectedController == null && !preferredControllers.isEmpty())
{
index++;
if (index >= preferredControllers.size())
index = 0;
selectedController = (ControllerInfo) preferredControllers.get(index);
// check that the selected controller can be used (ie. its vdb is up)
if (selectedController != null
&& !super.isVdbUpOnController(selectedController))
{
selectedController = null;
// we removed a controller => index must be decremented
index--;
if (index < 0)
index = 0;
}
}
This will loop until the timeout expires
