Aleksei created HTTPCLIENT-1923:
-----------------------------------
Summary: Not properly closing connections in
BasicHttpClientConnectionManager
Key: HTTPCLIENT-1923
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1923
Project: HttpComponents HttpClient
Issue Type: Bug
Components: HttpClient (classic)
Affects Versions: 4.5.5
Reporter: Aleksei
Seems we are hitting something similiar to the HTTPCLIENT-1655 issue, where
established connections were not properly closed (client sends Reset instead of
FIN+ACK)
We are using
BasicHttpClientConnectionManager (4.5.5 httpclient version)
and when we are calling client.close(), we see packet with Reset flag enabled
in tcpdump
Looks like here:
[https://github.com/apache/httpcomponents-client/blob/4.5.x/httpclient/src/main/java/org/apache/http/impl/conn/BasicHttpClientConnectionManager.java#L378]
must be closeConnection()
[https://github.com/apache/httpcomponents-client/blob/4.5.x/httpclient/src/main/java/org/apache/http/impl/conn/BasicHttpClientConnectionManager.java#L209]
instead of shutdownConnection
This issue is not present if we are using PoolingHttpClientConnectionManager
(in shutdown() there are pool.shutdown:
[https://github.com/apache/httpcomponents-client/blob/4.5.x/httpclient/src/main/java/org/apache/http/impl/conn/PoolingHttpClientConnectionManager.java#L410]
where for each entry runs: entry.close(){color:#cc7832} ->
this{color}.closeConnection(){color:#cc7832};{color}) - we see normal
connection close (FIN+ACK)
What do you think about it?
Thank you
