Oleg Kalnichevski resolved HTTPCLIENT-1104.
-------------------------------------------
Resolution: Fixed
Fix Version/s: (was: 4.2 Final)
4.2 Alpha1
New connection pool and pooling connection manager implementations now expose
pool stats such number of leased & available connections. Stats can be obtained
either for a particular route or the entire pool.

> Key: HTTPCLIENT-1104
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1104
> Project: HttpComponents HttpClient
> Issue Type: Improvement
> Components: HttpClient
> Reporter: John Karp
> Priority: Minor
> Fix For: 4.2 Alpha1
>
>
> As the documentation emphasizes, its important to clean up HttpEntities after
> use, so they don't tie up the default very small number of connections in the
> pool.
> However, nothing is provided to HttpClient users with the default classes
> that allows them to unit test their code to help verify that they are in fact
> properly releasing the connections under all circumstances. One way this
> could be done is for the API to expose the number of current leased (taken)
> connections in the pool, which would be
> connManager.pool.leasedConnections.size() if not for the necessary fields
> being protected. If this statistic were published through the API, user unit
> tests could check that it is zero when they finish.
> A workaround is for the user to subclass both the connection manager and
> ConnPoolByRoute and add getter methods. But its kind of a clunky solution,
> and I think the API should be written to encourage its users to perform this
> check.
