EntityUtils.toString() doesn't detect/report less content being returned than
was promised
------------------------------------------------------------------------------------------
Key: HTTPCORE-235
URL: https://issues.apache.org/jira/browse/HTTPCORE-235
Project: HttpComponents HttpCore
Issue Type: Bug
Components: HttpCore
Affects Versions: 4.0.1
Reporter: Steve Loughran
Also on my review of EntityUtils.toString(), I see that it's code to take an
input stream and a content length only uses the content length parameter to set
the size of the buffer -there is no attempt to verify that the amount of data
received was as expected and raise an {{IOException}} if less data arrived.
While this code will appear to work, especially on loopback and local
connections, it is flawed long-haul where connections are often dropped early.
I propose streaming the entity content to a byte array, validating the length,
then building a string in the appropriate charset from the buffer if it is
valid.
