Subject [jira] [Resolved] (HTTPCLIENT-1273) DecompressingHttpClient rethrows an HttpException as an IOException
Date Wed, 12 Dec 2012 10:47:22 GMT

     [ https://issues.apache.org/jira/browse/HTTPCLIENT-1273?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Oleg Kalnichevski resolved HTTPCLIENT-1273.

    Resolution: Fixed

Re-throwing of HTTP protocol exception as an i/o exception is intentional. All HttpClient
implementations follow that convention. The problem is that they are also expected to take
care of resource deallocation in case of _any_ abnormal situation, be it an i/o, HTTP or runtime
error. DecompressingHttpClient obviously was not doing that. Fixed in both SVN trunk and 4.2.x.
Please re-test / review.

> The execute() method of DecompressingHttpClient catches an HttpException and rethrows
it as a ClientProtocolException, which is an IOException. The documentation and examples state
clearly that when an HttpException is thrown, resources must be released (abort(), consume(),
etc.), but when an IOException is thrown, the connection is closed for you. By rethrowing
the wrong type, people (like me) are deeply puzzled, as after getting an IOException an attempt
to reuse the connection generates a "still allocated" exception, which should not happen (if
you believe the documentation).
