-------------------------------------
Summary: LengthDelimitedEncoder fails on content length > 32 bit
Key: HTTPCORE-312
URL: https://issues.apache.org/jira/browse/HTTPCORE-312
Project: HttpComponents HttpCore
Issue Type: Bug
Components: HttpCore NIO
Affects Versions: 4.2
Reporter: Roland Hänel
Priority: Critical
The LengthDelimitedEncoder class fails to deliver contents that are larger than
2GB, because the write(final ByteBuffer src) method incorrectly calculates
int lenRemaining = (int) (this.contentLength - this.len);
For example, if this.contentLength is 3,000,000,000 and this.len is 0, then
lenRemaining will be negative and things will go wrong in the process.
Changing the line to
long lenRemaining = this.contentLength - this.len;
will fix this bug (maybe src.remaining() needs to be casted to (long) in the
following if statement).
