Antoine Pitrou 94c33ebfa8 Issue #7610: Reworked implementation of the internal 
:class:`zipfile.ZipExtFile` class used to represent files stored inside
an archive.  The new implementation is significantly faster and can
be wrapped in a :class:`io.BufferedReader` object for more speedups.
It also solves an issue where interleaved calls to `read()` and
`readline()` give wrong results.  Patch by Nir Aides.

Amaury Forgeot d'Arc 2407ac9a4b follow-up of #3997: since 0xFFFF numbers are not enough to indicate a zip64 format, 
always try to read the "zip64 end of directory structure".

Gregory P. Smith b89a096d6d Use zlib's crc32 routine instead of binascii when available. zlib's is faster 
when compiled properly optimized and about the same speed otherwise.

Gregory P. Smith da407232e0 Document that zipfile decryption is insanely slow and fix a typo and 
blatant lie in a docstring (it is not useful for security regardless of
how you spell it).

Gregory P. Smith 0c63fc23c4 Fix zipfile decryption. The check for validity only worked on one 
type of encrypted zip files.  Files using extended local headers
needed to compare the check byte against different values.  (according
to reading the infozip unzip crypt.c source code)

Fixes issue1003.

Tim Peters f79c32dbfb ZipFile.close(): Kill the other struct.pack deprecation 
warning on Windows.

Afraid I can't detect a pattern to when the pack formats decide
to use a signed or unsigned format code -- appears nearly
arbitrary to my eyes.  So I left all the pack formats alone and
changed the special-case data values instead.

Tim Peters 352bf0d7ee ZipFile.close(): Killed one of the struct.pack deprecation 
warnings on Win32.

Also added an XXX about the line:

                pos3 = self.fp.tell()

`pos3` is never referenced, and I have no idea what the code
intended to do instead.

Brett Cannon ff450f7512 Make struct formats for specifying file size to be unsigned instead of signed 
(ZIP file spec. says in section K, "General notes" in point 1 that unless
specified otherwise values are unsigned and they are not specified as signed in
the spec).
