Subject [jira] Created: (HTTPCORE-231) can not download file size greater than Integer.MAX_VALUE
Date Thu, 02 Sep 2010 17:31:53 GMT
can not download file size greater than Integer.MAX_VALUE
---------------------------------------------------------

                 Key: HTTPCORE-231
                 URL: https://issues.apache.org/jira/browse/HTTPCORE-231
             Project: HttpComponents HttpCore
          Issue Type: Bug
          Components: HttpCore NIO
    Affects Versions: 4.1-beta2
            Reporter: Yongxing Wang


We are using HTTP NIO in our production env and we recently found out that we
can not download any file with size greater than Integer.MAX_VALUE. The amount
of data we can download is always "actual_file_size - Integer.MAX_VALUE" in that
case.

Further looking into the code, I have found that the implementation of
LengthDelimitedDecoder there is a line of code:

int lenRemaining = (int) (this.contentLength - this.len);

I believe the cast to int is causing the problem when contentLength is over 4G.
Once I changed lenRemaining to long and make other necessary changes to let it
compile, it works great.
