Hey. I have a problem in some network code. I want to send my packets compressed, but I don't want to compress each packet separately (via .encode('zlib') or such) but rather I'd like to compress it with regard to the history of the compression stream. If I use zlib.compressobj and flush it to get the packet data, I cannot continue to compress with that stream.
I cannot wait until the end of the stream and then flush, because I need to flush after every packet. Another capability I require is to be able to copy the compression stream. i.e: To be able to create multiple continuations of the same compression stream. Something like: a = compressobj() pre_x = a.copy() x = a.compress('my_packet1') # send x # x was not acked yet, so we must send another packet via the pre_x compressor y = pre_x.compress('my_packet2') Is there a compression object that can do all this? -- http://mail.python.org/mailman/listinfo/python-list
