characters as mapping keys and invalid mapping keys are recognized
and raise an error.

Add md5module.c and sha1module.c to the project files,
and in some cases bytes_methods.c and related .h files.

Code that has been returning str8 becomes much more apparent thanks to this
(e.g., struct module returning str8 for all string-related formats or sqlite3
passing in str8 instances when converting objects that had a __conform__
method).  One also has to watch out in C code when making a key from char *
using PyString in the C code but a str instance in Python code as that will not
longer compare equal.

Once str8 gains a constructor like the current bytes type then
test_modulefinder needs a cleanup as the fix is a little messy in that file.

Thanks goes to Thomas Lee for writing the patch for the change giving an
initial run-down of why most of the tests were failing.

Additional patch by Christian Heimes to deal more cleanly with the
FILE* vs file-descriptor issues.
I cleaned up his code a bit, and moved the lseek() call into import.c.

beginning of a file through a file pointer is not reflected when reading from a
file descriptor.  Using both fflush() and fpurge() does not solve it.  One must
use lseek() directly on the file descriptor to get the desired effect.

This might suggest that we standardize on either file pointers (FILE) or file
descriptors (int) for all C code used.

was PyMem_MALLOC'ed.

Also tweak a comparison that was going farther than needed.

Move the initialization of sys.std{in,out,err} and __builtin__.open
to C code.
This solves the problem that "python -S" wouldn't work.

Make PyString's indexing and iteration return integers.
(I changed a few of Alexandre's decisions -- GvR.)

changes to codecs.c and structmember.c to use PyUnicode instead of
PyString.

in random rowid strings, pass txn using a keyword where possible.

I like this because it makes the code shorter! :-)

to be called a buffer).  Shares code with stringobject when possible.
Adds unit tests with common code that should be usable to test the PEPs
mutable buffer() and immutable bytes() types.

'newline' argument is not a jumbled mess of newlines.

Changes to make __file__ a proper Unicode object, using the default
filesystem encoding.
This is a bit tricky because the default filesystem encoding isn't
set by the time we import the first modules; at that point we fudge
things a bit.  This is okay since __file__ isn't really used much
except for error reporting.
Tested on OSX and Linux only so far.

Also fix some indentation.

returned by 'et' need to be freed after usage.

fix the error message of the 't' format unit, in getargs.c, so that it
asks for bytes, instead of string.

Adds a DBShelf __repr__ method to not raise an exception when the DB is closed.

Eliminate use of PyBUF_CHARACTER flag which is no longer part of the buffer interface.  Fix up array module to export the correct format for wide-builds.

Fix problems with memoryview object.  There is still more to do to finish PEP 3118.  The memory-view object needs to be fleshed out and the struct module needs to be modified.

Add macros for checking for long double and defining the size of long double on the platform.  Ctypes and Struct module will both need them.

Fix Issue 1268 with the array module by backing-out the 'w' addition.  All builds will continue to use 'u' for unicode.
