---------------------------------------
Hello Phil Steitz,
thanks for your eMail. Here a have an test case that reproduces the bug.
test case
========
String serverName = "localhost";
String serverDB = "localweb";
String user1 = "doris";
String password1 = "doris";
String user2 = "cramer";
String password2 = "cramer";
Connection con = null;
PGConnectionPoolDataSource ConPoolDS = new
PGConnectionPoolDataSource();
ConPoolDS.setServerName(serverName);
ConPoolDS.setDatabaseName(serverDB);
ConPoolDS.setUser(user1);
ConPoolDS.setPassword(password1);
// --------------------------------------
// dbcp caching via SharedPoolDataSource
// --------------------------------------
SharedPoolDataSource SharedDS = new SharedPoolDataSource();
SharedDS.setConnectionPoolDataSource(ConPoolDS);
SharedDS.setMaxActive(10); // 0 = no limit
SharedDS.setMaxIdle(10);
SharedDS.setMinEvictableIdleTimeMillis(1000);
SharedDS.setMaxWait(1000); // -1 = no limit
SharedDS.setTimeBetweenEvictionRunsMillis(1000);
SharedDS.setTestWhileIdle(true);
try
{
con = SharedDS.getConnection(user1, password1);
}
catch (Exception e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
try
{
con = SharedDS.getConnection(user2, "wrongpassword");
}
catch (Exception e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
try
{
// connection will fail because the wrong password is
stored in the usersKey map.
con = SharedDS.getConnection(user2, password2);
}
catch (Exception e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
steps to reproduce
================
The SharedPoolDataSource saves wrong password forever
1. Get a connection for user1 (use username of user1 and password of user1)
---> connection ok
2. Get a connection for user2 (use username of user2 and a wrong password) -->
connection failed
3. Get a connection for user2 (use username of user2 and password of user2) -->
connection will be failed too because the wrong password is stored in the
usersKey map.
