I am fooling around with accessing contents of zip files online. I download the tail end of the zip and use zipfile to get the zip central directory structure. I download the section of the zip file I need, directly read the zip file headers and use that information with zlib to uncompress the data. The files I am examining will always be compressed using deflate, with a wbits value of -15(minus for headerless data because I am unsure whether the zip file header is what zlib expects).
I can not find anywhere in the PK Zip Application notes ( http://www.pkware.com/documents/casestudies/APPNOTE.TXT ) how to determine the value I should uze for wbits with zlib.decompress. I have determined it is -15 from experimentation. Does anyone know the answer to this? -- http://mail.python.org/mailman/listinfo/python-list
