[jira] [Commented] (HTTPCLIENT-2262) Clarify infinite timeout vs disabled timeout
[ https://issues.apache.org/jira/browse/HTTPCLIENT-2262?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17700093#comment-17700093 ]
Nicolas Filotto commented on HTTPCLIENT-2262:
---------------------------------------------
The timeouts defined in HttpClient seem to be provided as-is to the HttpCore components like in this example https://github.com/apache/httpcomponents-client/blob/master/httpclient5/src/main/java/org/apache/hc/client5/http/impl/classic/InternalExecRuntime.java#L99-L103
> Clarify infinite timeout vs disabled timeout
> --------------------------------------------
>
> Key: HTTPCLIENT-2262
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2262
> Project: HttpComponents HttpClient
> Issue Type: Task
> Components: HttpClient (classic)
> Affects Versions: 5.2.1
> Reporter: Nicolas Filotto
> Priority: Major
>
> I have a question regarding the expected behavior when setting a timeout to 0.
> In HttpClient, If I read for example [the Javadoc of the {{connectionRequestTimeout}}|https://github.com/apache/httpcomponents-client/blob/master/httpclient5/src/main/java/org/apache/hc/client5/http/config/RequestConfig.java#L427], it tells me that a timeout of 0 is infinite.
> In HttpCore, If I read [the Javadoc of {{Timeout#DISABLED}}|https://github.com/apache/httpcomponents-core/blob/master/httpcore5/src/main/java/org/apache/hc/core5/util/Timeout.java#L58], it tells me that the timeout is simply disabled when set to 0 but what disabled means precisely?
> If I keep digging in HttpCore, I see several classes like {{StrictConnPool}} that leverage {{Future}} and {{Lock}} for which a timeout set to 0, means that we expect an immediate result either with a success or a {{TimeoutException}}, so I assume that it is what we mean by "disabled timeout" but if so it would mean that it is in conflict with an infinite timeout as I personally don't expect to get a {{TimeoutException}} in case of an infinite timeout but maybe I'm wrong and it just needs to be clarified?
