Hi, I'm currently working on the implementation of the WebSocket permessage-deflate extension for Apache Tomcat. I am using the JRE provided classes java.util.zip.[Inflator|Defaltor] to do the compression and decompression.
I have a working implementation but there is one feature I can't implement because the necessary API isn't available. The WebSocket permessage-deflate specification [1] allows both the client and server to specify a number between 8 to 15 inclusive indicating the base-2 logarithm of the LZ77 sliding window size. The purpose of this feature is to enable both the client and the server to limit the size of the buffer they need to maintain to reduce their memory footprint per connection. Would it be possible for the java.util.zip.Inflator and java.util.zip.Defaltor API to be extended to expose the LZ77 window size? My suggestion would be an additional constructor for each class that took and additional int parameter for window size but I'd be happy with any API that provided control of the window size.
