           Summary: Take into account the minIdle in the
                    GenericObjectPool.evict method
           Product: Commons
           Version: 1.2 Final
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: Pool
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: michael.public@wavecorp.com


The minIdle attribute is not taken into account when the evict method is run. 
As a consequence, when the evict method gets called by the Evictor, it will
remove all (up to the number returned by getNumTests()) of the idle resources
first.  The Evictor must then make an additional call to the ensureMinIdle
method to just re-create minIdle resources.  For resources like socket
connections, this process is non-trivial and will cause a large number of
unnecessary I/O.

If this is deemed to not apply to all circumstances, then a nice alternative
would be to make the remove/add behavior a configurable option to the
GenericObjectPool.

------- Additional Comments From Sandy@McArthur.org  2006-02-07 01:15 -------
I think what you want is already there, see: GenericObjectPool.setSoftMinEvictableIdleTimeMillis(long)

The "hard" evict settings (GOP.setMinEvictableIdleTimeMillis(long)) are more concerned with evicting after 
a specified amount of time than maintaining the min idle count.
