Subject [jira] [Commented] (HTTPCLIENT-1830) IdleConnectionEvictor created by HttpClientBuilder should awaitTermination on shutdown
Date Mon, 20 Mar 2017 09:50:41 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1830?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15932406#comment-15932406

Liam Williams commented on HTTPCLIENT-1830:

Hey Oleg,

Sure, I am not too fussed about the implementation details, my goal is just to make sure that
we await termination when a client is closed.

Beware though, if I recall correctly there are two usages of the IdleConnectionEvictor, one
in HttpClientBuilder and another in HttpAsyncClientBuilder so both of those would need to
await termination.

The exception handling is a separate concern, but I noticed that we were previously just swallowing
the exception and so possibly losing visibility of it in the logs.

I'll update the pull requests for 4.5.x and 4.6.x with the minimal change you suggested and
apply a similar change to master but with the added exception logging.

How does that sound?

> When calling InternalHttpClient.close via the CloseableHttpClient interface for a client
created via HttpClientBuilder, IdleConnectionEvictor.shutdown is called, but IdleConnectionEvictor.awaitTermination
is not.
> This is a problem, since there is no way to await termination apart from doing a dirty
> Hope this makes sense, let me know if it doesn't.
