request. Tim says that "correct 'fuzzy' comparison of floats cannot
be automated." (The motivation behind adding the new option
was verifying interactive examples in Python's latex documentation;
several such examples use numbers that don't print consistently on
different platforms.)
Also, add a testcase.
Formerly, the list_extend() code used several local variables to remember
its state across iterations. Since an iteration could call arbitrary
Python code, it was possible for the list state to be changed. The new
code uses dynamic structure references instead of C locals. So, they
are always up-to-date.
After list_resize() is called, its size has been updated but the new
cells are filled with NULLs. These needed to be filled before arbitrary
iteration code was called; otherwise, that code could attempt to modify
a list that was in a semi-invalid state. The solution was to change
the ob->size field back to a value reflecting the actual number of valid
cells.
its documentation.
* Documented that the compiled re methods are supposed to be more full
featured than their simpilified function counterparts.
* Documented the existing start and stop position arguments for the
findall() and finditer() methods of compiled regular expression objects.
* Added an optional flags argument to the re.findall() and re.finditer()
functions. This aligns their API with that for re.search() and
re.match().
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.
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.

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.
