> Key: HTTPCLIENT-2298
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2298
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Affects Versions: 5.2.1
> Reporter: Kristijan Postolov
> Priority: Minor
> Fix For: 5.2.2, 5.3-alpha2
>
>
> I was upgrading to the new httpclient5 (more specifically 5.2.1) and noticed
> an issue where the StrictConnPool does not return accurate stats for the
> number of pending request.
>
> I created an httpClient with connectionRequestTimeout=2000 (2 seconds),
> responseTimeout=12000 (12s) and maxConnTotal=1 on the
> poolingHttpClientConnectionManager.
> The connection request timeout works as expected, when I make a slow request
> that runs for 10 seconds, and in the meantime I start a second one, the
> second request will fail after 2 seconds, as there is no available connection.
>
> However, after the 2 seconds, when the second connection throws a timeout
> exception I check the
> poolingHttpClientConnectionManager.getTotalStats().getPending(),
> I am still receiving 1 (meaning there is one request that is waiting for a
> free connection), even though this is not true since the request timed out
> after the configured 2 seconds.
> This number gets back to 0, only when the first connection is released (the
> first 10 second request finishes). I checked the same behavior with the old
> client (httpclient 4.5.14) and there the pending requests was decremented
> right after the connection request timeout is reached.
