today. pyconfig.h can override it if not, and can also override
Py_IS_INFINITY now. Py_IS_NAN and Py_IS_INFINITY are overridden now
for Microsoft compilers, using efficient MS-specific spellings.
When an integer is compared to a float now, the int isn't coerced to float.
This avoids spurious overflow exceptions and insane results. This should
compute correct results, without raising spurious exceptions, in all cases
now -- although I expect that what happens when an int/long is compared to
a NaN is still a platform accident.
Note that we had potential problems here even with "short" ints, on boxes
where sizeof(long)==8. There's #ifdef'ed code here to handle that, but
I can't test it as intended. I tested it by changing the #ifdef to
trigger on my 32-bit box instead.
I suppose this is a bugfix candidate, but I won't backport it. It's
long-winded (for speed) and messy (because the problem is messy). Note
that this also depends on a previous 2.4 patch that introduced
_Py_SwappedOp[] as an extern.
- Reorganized the documentation
- Shifted focus a little more towards "literate testing"
- Documented new functions and classes:
- testfile()
- Example, DocTest
- DocTestParser, DocTestFinder, DocTestRunner, OutputChecker
- DocFileSuite
- DebugRunner, DocTestFailure, UnexpectedException
- register_optionflag()
displaying a set of classes from one module it doesn't matter, but if you
are displaying a large class tree from multiple modules it improves the
display to sort by module.name.
all examples in a given text file. (analagous to "testmod")
- Minor docstring fixes.
- Added module_relative parameter to DocTestFile/DocTestSuite, which
controls whether paths are module-relative & os-independent, or
os-specific.
Make PySequence_Check() and PyMapping_Check() handle NULL inputs. This
goes beyond what most of the other checks do, but it is nice defensive
programming and solves the OP's problem.
Suggested settings are commented out and included at the end of the file.
The goal is to have this file prevent as much as possible from deviating from the style guidelines. It is not meant to collect every cool macro possible for Python. Any useful settings for features included with Vim can be included and commented out, but anything overly extraneous should be left out.

Various code cleanups and optimizations (saves about 40% on testsuite
execution time and on the telco benchmark).
* caches results of various operations on self (esp. checks for being
a special value).
* _WorkRep now uses ints and longs for intermediate computations.
- Minor wording changes
- Changed the docs to reflect the fact that multiple option directives
can be specified on a single line (and updated the directive
production list, as well).
- Fixed bug in handling of absolute paths.
- If run from an interactive session, make paths relative to the
directory containing sys.argv[0] (since __main__ doesn't have
a __file__ attribute).
of the Template.delimiter attribute, we make use of the delimiter in the
escaped group, and in the safe_substitute() method more robust.
Now, .delimiter should be the unescaped delimiter literal, e.g. '$' or '&', or
whatever. The _TemplateMetaclass will re.escape() this value when it builds
the pattern.
High level error message was stomping useful detailed messages from lower
level routines.
The new approach is to augment string error messages returned by the low
level routines. The provides both high and low level information. If
the exception value is not a string, no changes are made.
To see the improved messages in action, type:
import random
class R(random): pass
class B(bool): pass
