Fix a buglet in binascii.crc32, the second optional argument could previously

f48f9d38c0
Force zlib.crc32 and zlib.adler32 to return a signed integer on all platforms
...
regardless of the native sizeof(long) used in the integer object.
This somewhat odd behavior of returning a signed is maintained in 2.x for
compatibility reasons of always returning an integer rather than a long object.
Fixes Issue1202 for Python 2.6

Remove a number of tests that differ only in input data size. It seems

no bug motivated their inclusion and the chance of them triggering a
problem seems unlikely. Refactor to reduce code duplication. Rename

SF bug #785222 : zlib monotonic test

For smaller datasets, it is not always true the increasing the compression
level always results in better compression. Removed the test which made
this invalid assumption.

- Thanks to Scott David Daniels, a subtle bug in how the zlib
...
extension implemented flush() was fixed. Scott also rewrite the
zlib test suite using the unittest module. (SF bug #640230 and
patch #678531.)
Backport candidate I think.

Get rid of relative imports in all unittests. Now anything that
...
imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".
This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).
Now Tim and Jack can have at it. :)

[ #403753 ] zlib decompress; uncontrollable memory usage
...
Mostly by Toby Dickenson and Titus Brown.
Add an optional argument to a decompression object's decompress()
method. The argument specifies the maximum length of the return
value. If the uncompressed data exceeds this length, the excess data
is stored as the unconsumed_tail attribute. (Not to be confused with
unused_data, which is a separate issue.)
Difference from SF patch: Default value for unconsumed_tail is ""
rather than None. It's simpler if the attribute is always a string.
