Motivation:
Chunks are splitted up into even smaller chunks when the underlying
buffer's readable bytes are less than the chunk size.
The underlying buffer can be smaller than a chunk size if:
- The chunk size is larger than the maximum plaintext chunk allowed by the TLS RFC,
see: io.netty.handler.ssl.SslHandler.MAX_PLAINTEXT_LENGTH.
- The chunk sizes are variable in size,
which may cause Netty guess a buffer size that is smaller than a chunk size.
Modification:
Create a variable in HttpObjectDecoder: ByteBuf chunkedContent
- Initialize chunkedContent in READ_CHUNK_SIZE with chunkSize as buffer size.
- In READ_CHUNKED_CONTENT write bytes into chunkedContent
- If the remaining chunk size is not 0 and toRead ==maxChunkSize,
create a chunk using the chunkedContent and add it to the output messages
before re-initializing chunkedContent with the remaining chunkSize as buffer size.
- If the remaining chunk size is not 0 and toRead != maxChunkSize,
return without adding any output messages.
- If the remaining chunk size is 0,
create a chunk using the chunkedContent and add it to the output messages;
set chunkedContent = null and fall-through.
Result:
Support chunk sizes higher than the underlying buffer's readable bytes.
