Subject: [ruby-core:45310] [ruby-trunk - Feature #5937] Zlib::Inflate#add_dictionary to pre-supply dictionaries for inflate streams


Issue #5937 has been updated by drbrain (Eric Hodel).


I think #5929 should be backported instead.  While #5937 makes working with custom dictionaries easier, #5929 fixes the current API (#set_dictionary) to be fully usable.

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.
