This changes the main documentation, doc strings, source code comments, and a
couple error messages in the test suite. In some cases the word was removed
to fix the grammar.
module when the openssl version is too old to support them. That
leads both compiled code bloat and to unittests attempting to test
implementations that don't exist for comparison purposes on such
platforms.
to hashlib functions in python 2.x. The module now uses the 's*' for argument
parsing which auto encodes unicode objects to the system default encoding for
us.
to an unsigned int (and back again) on 64-bit machines, even though the
actual value of the Py_ssize_t variable is way below 31 bits. I suspect
compiler-error.
In C++, it's an error to pass a string literal to a char* function
without a const_cast(). Rather than require every C++ extension
module to put a cast around string literals, fix the API to state the
const-ness.
I focused on parts of the API where people usually pass literals:
PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type
slots, etc. Predictably, there were a large set of functions that
needed to be fixed as a result of these changes. The most pervasive
change was to make the keyword args list passed to
PyArg_ParseTupleAndKewords() to be a const char *kwlist[].
One cast was required as a result of the changes: A type object
mallocs the memory for its tp_doc slot and later frees it.
PyTypeObject says that tp_doc is const char *; but if the type was
created by type_new(), we know it is safe to cast to char *.
A new hashlib module to replace the md5 and sha modules. It adds
support for additional secure hashes such as SHA-256 and SHA-512. The
hashlib module uses OpenSSL for fast platform optimized
implementations of algorithms when available. The old md5 and sha
modules still exist as wrappers around hashlib to preserve backwards
compatibility.
