Python 3.4: zlib, deflate and shared dict -

-

any ideas how fix following code (python 3.4.3):

import zlib   hello = b'hello'  co = zlib.compressobj(wbits=-zlib.max_wbits, zdict=hello) data = co.compress(hello) + co.flush()  = zlib.decompressobj(wbits=-zlib.max_wbits, zdict=hello) data = do.decompress(data)  print(data)

fails me with

zlib.error: error -3 while decompressing data: invalid distance far

what trying decompress deflate compressed shared dictionary.

you can't use negative wbits dictionary. negative wbits gets rid of zlib header , trailer, zlib header how decompress knows use dictionary.

just rid of wbits options.

i understand in c# class passed reference. mean when store said class in list stored reference well, or better said c# style "pointer" of sorts? mean list n elements of class not take memory n times size of class n times size of reference class? or thinking wrong? you're right. if create n elements of class t, , class t uses, say, 10 bytes, takes on order of 10*n memory. if store in list<t> , still have 10*n memory objects, plus n times size of c# reference , list overhead. if store same elements in 2 lists, have 10*n objects, plus 2*n references, , 2 times list overhead. they're pointing @ same underlying objects.
