Changed all references to the MAGIC constant to use a global
pyc_magic instead. This global is initially set to MAGIC, but can be
changed by the _PyImport_Init() function to provide for
special features implemented in the compiler which are settable
using command line switches and affect the way PYC files are
generated.

Currently this change is only done for the -U flag.

(1) Added and documented the capability for shlex to handle
lexical-level inclusion and a stack of input sources.  Also, the input
stream member is now documented, and the constructor takes an optional
source-filename.  The class provides facilities to generate error
messages that track file and line number.

(2) Add a convenience function to generate C-compiler style error
leaders.

[GvR: I changed the __main__ code so that it actually stops at EOF, as
Eric surely intended -- however it returned '' instead of the None he
was testing for.]

Added Py_UnicodeFlag for use by the -U command line option.

Support for the new -U command line option option:
with the option enabled the Python compiler
interprets all "..." strings as u"..." (same with r"..." and
ur"...").

Added -U command line option.

1.6a2 caused by wrong return values in routine allcaps83.  [GvR: I
also changed the case for end-s>8 to return 0.]

previous functionality utime(path, (atime, mtime)), now allowed is
utime(path, None) which sets the file's times to the current time.

The two methods .readline() and .readlines() in StreamReaderWriter
didn't define the self argument. Found by Tom Emerson.

utime(path, NULL) call, setting the atime and mtime of the file to the
current time.  The previous signature utime(path, (atime, mtime)) is
of course still allowed.

Store sys.exc_info()[:2] instead.

because we've added Unicode marshalling to the repertoire.

sufficiently robust to survive the creation of bookmarks in the PDF
format.

Made the attributes more XHTML-friendly.

bad link URLs in HTML, etc.

???/*.css and ???/*.html -- need to pick up the Distutils manuals!

Follow a suggestion in an /*XXX*/ comment [in com_add()] to speed up
compilation by using supplemental dictionaries to keep track of names
and constants, eliminating quadratic behavior.  With this patch in
place, the time to import a 5000-line file with lots of constants [at
the global level] is reduced from 20 seconds to under 3 on my system.

Here's a patch which changes modsupport to add 'u' and 'u#',
to support building Unicode objects from a null-terminated
Py_UNICODE *, and a Py_UNICODE * with length, respectively.

[Conversion from 'U' to 'u' by Fred, based on python-dev comments.]

Note that the use of None for NULL values of the Py_UNICODE* value is
still in; I'm not sure of the conclusion on that issue.

remaining object references if the environment variable PYTHONDUMPREFS
exists.  The default behaviour caused problems for background or
otherwise invisible processes that use the debug build of Python.

Fixes a memory leak found by Fredrik Lundh.

Doc strings can now be given as Unicode strings.

Fixed a reference leak in the allocator.

Renamed utf8_string to _PyUnicode_AsUTF8String() and made
it external for use by other parts of the interpreter.

Fixed a memory leak found by Fredrik Lundh.  Instead of
PyUnicode_AsUTF8String() we now use _PyUnicode_AsUTF8String() which
returns the string object without incremented refcount (and assures
that the so obtained object remains alive until the Unicode object is
garbage collected).

in certain circumstances.  (Apparently, this is a CPython problem.)

  it is forcibly prepended onto all installation directories, even if
  they are already absolute.
Added 'dump_dirs()' to clean up the debug output a bit.

even if it's already absolute.  Currently only implemented for Unix; I'm
not entirely sure of the right thing to do for DOS/Windows, and have no
clue what to do for Mac OS.

This patch is a workaround for Macintosh, where the GUSI I/O library
(time, stat, etc) use the MacOS epoch of 1-Jan-1904 and the MSL C
library (ctime, localtime, etc) uses the (apparently ANSI standard)
epoch of 1-Jan-1900. Python programs see the MacOS epoch and we
convert values when needed.

The previous checkin (2.84) added a PyErr_Format call that made the
cost of raising an AttributeError much more expensive.  In general
this doesn't matter, except that checks for __init__ and
__del__ methods, where exceptions are caught and cleared in C, also
got much more expensive.

The fix is to split instance_getattr1 into two calls:

instance_getattr2 checks the instance and the class for the attribute
and returns it or returns NULL on error.  It does not raise an
exception.

instance_getattr1 does rexec checks, then calls instance_getattr2.  It
raises an exception if instance_getattr2 returns NULL.

PyInstance_New and instance_dealloc now call instance_getattr2
directly.
