Guido van Rossum 47b9ff6ba1 Restructure comparison dramatically. There is no longer a default
*ordering* between objects; there is only a default equality test
(defined by an object being equal to itself only).  Read the comment
in object.c.  The current implementation never uses a three-way
comparison to compute a rich comparison, but it does use a rich
comparison to compute a three-way comparison.  I'm not quite done
ripping out all the calls to PyObject_Compare/Cmp, or replacing
tp_compare implementations with tp_richcompare implementations;
but much of that has happened (to make most unit tests pass).

The following tests still fail, because I need help deciding
or understanding:

test_codeop -- depends on comparing code objects
test_datetime -- need Tim Peters' opinion
test_marshal -- depends on comparing code objects
test_mutants -- need help understanding it

The problem with test_codeop and test_marshal is this: these tests
compare two different code objects and expect them to be equal.
Is that still a feature we'd like to support?  I've temporarily
removed the comparison and hash code from code objects, so they
use the default (equality by pointer only) comparison.

For the other two tests, run them to see for yourself.
(There may be more failing test with "-u all".)

A general problem with getting lots of these tests to pass is
the reality that for object types that have a natural total ordering,
implementing __cmp__ is much more convenient than implementing
__eq__, __ne__, __lt__, and so on.  Should we go back to allowing
__cmp__ to provide a total ordering?  Should we provide some other
way to implement rich comparison with a single method override?
Alex proposed a __key__() method; I've considered a __richcmp__()
method.  Or perhaps __cmp__() just shouldn't be killed off...

Thomas Wouters dcc6d32ee4 Fix merge glitch. 2006-04-21 11:30:52 +00:00
Thomas Wouters 49fd7fa443 Merge p3yk branch with the trunk up to revision 45595. This breaks a fair
number of tests, all because of the codecs/_multibytecodecs issue described
here (it's not a Py3K issue, just something Py3K discovers):
http://mail.python.org/pipermail/python-dev/2006-April/064051.html

Hye-Shik Chang promised to look for a fix, so no need to fix it here. The
tests that are expected to break are:

test_codecencodings_cn
test_codecencodings_hk
test_codecencodings_jp
test_codecencodings_kr
test_codecencodings_tw
test_codecs
test_multibytecodec

This merge fixes an actual test failure (test_weakref) in this branch,
though, so I believe merging is the right thing to do anyway.

Raymond Hettinger 267b868f23 * Fix decimal's handling of foreign types. Now returns NotImplemented
instead of raising a TypeError.  Allows other types to successfully
  implement __radd__() style methods.
* Remove future division import from test suite.
* Remove test suite's shadowing of __builtin__.dir().

* The decimal module wouldn't load on builds without threads.

Raymond Hettinger 605ed02483 SF bug #1071588 coercing decimal to int doesn't work between -1 and 1 2004-11-24 07:28:48 +00:00
Raymond Hettinger ed20ad8473 Change the strategy for coping with time intensive tests from
"all or none" to "all or some".

This provides much greater test coverage without eating much time.
It also makes it more likely that routine regression testing will
unearth bugs.

Raymond Hettinger f04d8a8898 There are no longer any special case test skips. 2004-08-17 16:34:51 +00:00
Raymond Hettinger f63ba43733 * Dynamically build a list of files to be tested (necessary because
version 2.39 of dectest.zip adds some new test files and because
  some existing test files were getting skipped).
* Remove two docstrings which cluttered unittest's output.
* Simplify a for-loop with a list comprehension.

Raymond Hettinger 955d2b2168 Add a test for Context.copy(). 2004-08-08 20:17:45 +00:00
Raymond Hettinger b91af521fd * Hide a loop induction variable that was inadvertantly being picked up
by the locals() call in the context constructor.

* Remove unnecessary properties for int, exp, and sign which duplicated
  information returned by as_tuple().

Raymond Hettinger fed52963fc * Rename "Signals" to "_signals" making it non-public.
* Context.create_decimal can take a zero default just like Decimal().
* Fix typo in comment.

Raymond Hettinger bf4406971c Improve Context construction and representation:
* Rename "trap_enablers" to just "traps".
* Simplify names of "settraps" and "setflags" to just "traps" and "flags".
* Show "capitals" in the context representation
* Simplify the Context constructor to match its repr form so that only
  the set flags and traps need to be listed.
* Representation can now be run through eval().

Improve the error message when the Decimal constructor is given a float.

The test suite no longer needs a duplicate reset_flags method.

Raymond Hettinger d87ac8f24d * Update the test suite to reflect that ConversionSyntax was no longer
public.
* Removed the non-signal conditions from __all__.
* Removed the XXX comment which was resolved.
* Use ^ instead of operator.xor
* Remove the threading lock which is no longer necessary.
2004-07-09 10:52:54 +00:00
Raymond Hettinger 5aa478badf Module and tests:
* Map conditions to related signals.
* Make contexts unhashable.
* Eliminate used "default" attribute in exception definitions.
* Eliminate the _filterfunc in favor of a straight list.

Docs:
* Eliminate documented references to conditions that are not signals.
* Eliminate parenthetical notes such as "1/0 --> Inf" which are no
  longer true with the new defaults.
2004-07-09 10:02:53 +00:00
Raymond Hettinger 0aeac107ca * Add __eq__ and __ne__ so that things like list.index() work properly
for lists of mixed types.
* Test that sort works.

Raymond Hettinger 6ea4845822 * Make the tests independent of the default precision.
* Change the default precision to 28 (to match VB's decimal type).
2004-07-03 12:26:21 +00:00
Raymond Hettinger d9c0a7ae94 Work through several open todos:
* Added test for pickling contexts
* Renamed ExceptionList to Signals (to match wording in the spec)
* Simplified Context constructor by allowing flags=None to automatically
  generate a zeroed-out flags dictionary.
* inlined _convertString() which was used only once
* _rounding_decision is private, so excluded its contants from __all__.
* added an XXX comment with concerns about subclassing signals results in
  a deviation from the spec (maybe important, maybe not).
* Taught the test_suite to determine its own directory (modeled after code
  in regrtest.py).  Enables it to be run when the current directory is not
  the test directory.
* Added a clear_flags() method to the Context API to make it easier to do
  a common operation with flags.
* Fixed the trap_enablers defaults in BasicDefaultContext to match the spec.
