Guido van Rossum be4cbb1668 Use rich comparisons to fulfill an old wish: complex numbers now raise
exceptions when compared using <, <=, > or >=.

NOTE: This is a tentative change: this means that cmp() involving
complex numbers will raise an exception when the numbers differ, and
that in turn means that e.g. dictionaries and certain other compounds
(e.g. UserLists) containing complex numbers can't be compared either.
So we'll have to decide whether this is acceptable.  The alpha test
cycle is a good time to keep an eye on this!

Guido van Rossum 9d19cb8a70 Same treatment as listobject.c:
- In count(), remove(), index(): call RichCompare(Py_EQ).

- Get rid of array_compare(), in favor of new array_richcompare() (a
  near clone of list_compare()).

- Aligned items in array_methods initializer and comments for type
  struct initializer.

- Folded a few long lines.

Guido van Rossum b932420cc7 Rich comparisons:
- Use PyObject_RichCompareBool() when comparing keys; this makes the
  error handling cleaner.

- There were two implementations for dictionary comparison, an old one
  (#ifdef'ed out) and a new one.  Got rid of the old one, which was
  abandoned years ago.

- In the characterize() function, part of dictionary comparison, use
  PyObject_RichCompareBool() to compare keys and values instead.  But
  continue to use PyObject_Compare() for comparing the final
  (deciding) elements.

- Align the comments in the type struct initializer.

Note: I don't implement rich comparison for dictionaries -- there
doesn't seem to be much to be gained.  (The existing comparison
already decides that shorter dicts are always smaller than longer
dicts.)

Guido van Rossum f77bc62e73 Same treatment as listobject.c:
- tuplecontains(): call RichCompare(Py_EQ).

- Get rid of tuplecompare(), in favor of new tuplerichcompare() (a
  clone of list_compare()).

- Aligned the comments for large struct initializers.

Guido van Rossum 24f67d568c Fix a leak in instance_coerce(). This was introduced by Neil's
earlier coercion changes, not by rich comparisons.  When a coercion
function returns 1 (meaning it cannot do it), it should not INCREF the
arguments.  When no __coerce__() method was found, instance_coerce()
originally returned 0, pretending it did it.  Neil changed the return
value to 1, more accurately reflecting that it didn't do anything, but
forgot to take out the two INCREF calls.

Andrew M. Kuchling 6425efe9ae The signal module has to be compiled statically, so add it to Setup.dist
and remove support for it from setup.py

Guido van Rossum 65e1cea6e3 Convert to rich comparisons:
- sort's docompare() calls RichCompare(Py_LT).

- list_contains(), list_index(), listcount(), listremove() call
  RichCompare(Py_EQ).

- Get rid of list_compare(), in favor of new list_richcompare().  The
  latter does some nice shortcuts, like when == or != is requested, it
  first compares the lengths for trivial accept/reject.  Then it goes
  over the items until it finds an index where the items differe; then
  it does more shortcut magic to minimize the number of additional
  comparisons.

- Aligned the comments for large struct initializers.

Fredrik Lundh f785042433 a bold attempt to fix things broken by MAL's verify patch: import

2001-01-17 21:51:36 +00:00
Guido van Rossum f27cc5bc74 Marc-Andre must not have run these tests -- they used verify() but
didn't import it.  Also got rid of some inconsistent spaces inside
parentheses in test_gzip.py.

Guido van Rossum 2ffbf6b112 Deal properly (?) with comparing recursive datastructures.
- Use the compare nesting level and in-progress dictionary properly in
  PyObject_RichCompare().

- Change the in-progress code to use static variables instead of
  globals (both the nesting level and the key for the thread dict were
  globals but have no reason to be globals; the key can even be a
  function-static variable in get_inprogress_dict()).

- Rewrote try_rich_to_3way_compare() to benefit from the similarity of
  the three cases, making it table-driven.

- In try_rich_to_3way_compare(), test for EQ before LT and GT.  This
  turns out essential when comparing recursive UserList instances;
  with the old code, these would recurse into rich comparison three
  times for each nesting level up to NESTING_LIMIT/2, making the total
  number of calls in the order of 3**(NESTING_LIMIT/2)!

NOTE: I'm not 100% comfortable with this.  It works for the standard
test suite (which compares a few trivial recursive data structures
only), but I'm not sure that the in-progress dictionary is used
properly by the rich comparison code.  Jeremy suggested that maybe the
operation should be included in the dict.  Currently I presume that
objects in the dict are equal unless proven otherwise, and I set the
outcome for the rich comparison accordingly: true for operators EQ,
LE, GE, and false for the other three.  But Jeremy seems to think that
there may be counter-examples where this doesn't do the right thing.

Marc-André Lemburg 3661908a6a This patch removes all uses of "assert" in the regression test suite
and replaces them with a new API verify(). As a result the regression
suite will also perform its tests in optimization mode.

Marc-André Lemburg a544ea2354 Undoing the whitespace patches which sneaked into the earlier patch. 2001-01-17 18:04:31 +00:00
Marc-André Lemburg ad7c98e264 This patch adds a new builtin unistr() which behaves like str()
except that it always returns Unicode objects.

A new C API PyObject_Unicode() is also provided.

This closes patch #101664.

Guido van Rossum f98eda01ab News item for rich comparisons.
(I'm going to check in some more uses of rich comparisons, but the
basic feature should be in place now.)

Guido van Rossum ac7be6888b Rich comparisons fall-out:
- Use PyObject_RichCompare*() where possible: when comparing
  keyword arguments, in _PyEval_SliceIndex(), and of course in
  cmp_outcome().

Unrelated stuff:

- Removed all trailing whitespace.

- Folded some long lines.

Guido van Rossum 8998b4f691 Rich comparisons.
- Got rid of instance_cmp(); refactored instance_compare().

- Added instance_richcompare() which calls __lt__() etc.

Some unrelated stuff mixed in:

- Aligned comments in various large struct initializers.

- Better test to avoid recursion if __coerce__ returns self as the
  first argument (this is an unrelated fix by Neil Schemenauer!).

- Style nit: don't use Py_DECREF(Py_NotImplemented); use
  Py_DECREF(result) -- it just looks better. :-)

Guido van Rossum e797ec1cb8 Rich comparisons. Refactored internal routine do_cmp() and added APIs
PyObject_RichCompare() and PyObject_RichCompareBool().

XXX Note: the code that checks for deeply nested rich comparisons is
bogus -- it assumes the two objects are always identical, rather than
using the same logic as PyObject_Compare().  I'll fix that later.

Guido van Rossum 5f284ce68e Introduction to rich comparisons:
- Removed the nb_add slot from the PyNumberMethods struct.

- Renamed Py_TPFLAGS_NEWSTYLENUMBER to Py_TPFLAGS_CHECKTYPES.

- Added typedef richcmpfunc.

- Added tp_richcompare slot to PyTypeObject (replacing spare tp_xxx7).

- Added APIs PyObject_RichCompare() and PyObject_RichCompareBool().

- Added rich comparison operators Py_LT through Py_GE.

Andrew M. Kuchling c14fa303e1 Patch #103279: sysconfig.py always looks for versions of files in
sys.prefix + 'config/Makefile'. When building Python for the first
time, these files aren't there, so the files from the build tree have
to be used instead; this file adds an entry point for specifying that
the build tree files should be used.  (Perhaps 'set_python_build' should
should be preceded with an underscore?)

Guido van Rossum 846d6dbbe6 Fix a bizarre typo in the helper class ComparableException: the
__getattr__() method, which clearly (like the other methods) was
intended to pass the __getattr__() call on to the self.err object,
mistakenly returned getattr(self, self.err) rather than
getattr(self.err, attr).  Since self.err is not a string, this always
raises a TypeError.  Apparently that doesn't bother for the one
attribute for which __getattr__() is actually called ('__coerce__'),
but it broke the rich comparisons stuff that I'm trying to get into
shape, so I'm fixing this now.  (I could also simply remove the
__getattr__() method, but fixing it seems more in the spirit of what
the ComparableException class is trying to do.)

\t\t\t\t\treal code
##\t\t\t\t\tunused code

via untabifying and shifting the real code left.  Semantically the
same but made the intent of the commented-out-in-column-0 unused code
unclear.  The exact same unused code appears to have gotten copied from
file to file over the years.
