http://docs.python.org/library/zlib.html says "If max_length is not supplied then the whole input is decompressed, and unconsumed_tail is an empty string." However, if there's preceding decompress call with max_length specified, unconsumed_tail will not be empty. ---- import zlib c = zlib.compressobj(zlib.Z_DEFAULT_COMPRESSION, zlib.DEFLATED, -zlib.MAX_WBITS) compressed = c.compress('abc') compressed += c.flush(zlib.Z_SYNC_FLUSH) d = zlib.decompressobj(-zlib.MAX_WBITS) original = d.decompress(data, 1) original += d.decompress(d.unconsumed_tail) print "%r" % d.unconsumed_tail ---- Result is ---- '\x06\x00\x00\x00\xff\xff' ---- Document or code should be fixed. |

Thanks for the bug report. It seems that the code needs fixing. I'll look into it this weekend. |
