Summary

0004819: contentLength int vs long

Description

(rep by Aaron Freeman)

In AbstractHttpRequest I am seeing that the global variable _contentLength it appropriately a ?long?. Love that. Been a thorn in our side for a long time.

However in looking at this method (also inside of AbstractHttpRequest):

  protected void setContentLength(CharSegment value)

  {

    int contentLength = 0;

    int ch;

    int i = 0;

    int length = value.length();

    for (;

         i < length && (ch = value.charAt(i)) >= '0' && ch <= '9';

         i++) {

      contentLength = 10 * contentLength + ch - '0';

    }

    if (i > 0)

      _contentLength = contentLength;

  }

The method is internally using an int, so the values get truncated or ?wrapped? to negative values. Internally I believe that method should use a long for the local contentLength variable.

This should help prevent HttpRequest from incorrectly throwing this for request larger than 2GB (which is what the user community would see in their logs if they are dumping exceptions):

      throw new com.caucho.server.dispatch.BadRequestException("POST requires content-length");
