Subject: [ruby-core:45321] [ruby-trunk - Feature #5937] Zlib::Inflate#add_dictionary to pre-supply dictionaries for inflate streams


Issue #5937 has been updated by igrigorik (Ilya Grigorik).


@naruse: as Eric pointed out in his original ticket (#5929), I do believe this is a bug, as the current API advertises that it can set and use the dictionary, but that is not the case. 

I've opened a different / new ticket: http://bugs.ruby-lang.org/issues/6516

Feature #5937: Zlib::Inflate#add_dictionary to pre-supply dictionaries for inflate streams

The attached patch allows Zlib::Inflate users to supply dictionaries ahead of time in order to avoid handling the Zlib::NeedDict exception.

Multiple dictionaries may be provided.  Zlib::Inflate will choose a matching dictionary based on the adler32 checksum of the provided dictionaries.
