Florent Xicluna 6de9e938a5 Issue #7849: Now the utility ``check_warnings`` verifies if the warnings are
effectively raised.  A new utility ``check_py3k_warnings`` deals with py3k warnings.

Facundo Batista c11cecf3d0 Issue 1742669. Now %d accepts very big float numbers.
Thanks Gabriel Genellina.
2008-02-24 03:17:21 +00:00
Facundo Batista 57d5669f4b Now in find, rfind, index, and rindex, you can use None as defaults,
as usual with slicing (both with str and unicode strings).  This
fixes issue 1259.

For str only the stringobject.c file was modified.  But for unicode,
I needed to repeat in the four functions a lot of code, so created
a new function that does part of the job for them (and placed it in
find.h, following a suggestion of Barry).

Also added tests for this behaviour.
2007-11-16 18:04:14 +00:00
Thomas Wouters 3ccec68a05 Improve extended slicing support in builtin types and classes. Specifically:
- Specialcase extended slices that amount to a shallow copy the same way as
   is done for simple slices, in the tuple, string and unicode case.

 - Specialcase step-1 extended slices to optimize the common case for all
   involved types.

 - For lists, allow extended slice assignment of differing lengths as long
   as the step is 1. (Previously, 'l[:2:1] = []' failed even though
   'l[:2] = []' and 'l[:2:None] = []' do not.)

 - Implement extended slicing for buffer, array, structseq, mmap and
   UserString.UserString.

 - Implement slice-object support (but not non-step-1 slice assignment) for
   UserString.MutableString.

 - Add tests for all new functionality.

Tim Peters 80a18f0f9c Re-enable a new empty-string test added during the NFS sprint,

Andrew Dalke 005aee2c39 I like tests.
The new split functions use a preallocated list.  Added tests which exceed
the preallocation size, to exercise list appends/resizes.

Also added more edge case tests.

Tim Peters beaec0c3a1 We can't leave the checked-in tests broken. 2006-05-24 20:27:18 +00:00
Andrew Dalke e5488ec01e Added a slew of test for string replace, based various corner cases from
the Need For Speed sprint coding.  Includes commented out overflow tests
which will be uncommented once the code is fixed.

This test will break the 8-bit string tests because
    "".replace("", "A") == "" when it should == "A"

We have a fix for it, which should be added tomorrow.

Michael W. Hudson b2308bb9be Fix bug:
[ 1327110 ] wrong TypeError traceback in generator expressions

by removing the code that can stomp on the users' TypeError raised by the
iterable argument to ''.join() -- PySequence_Fast (now?) gives a perfectly
reasonable message itself.  Also, a couple of tests.

Raymond Hettinger 57e7447c44 * Beef-up tests for str.count().
* Speed-up str.count() by using memchr() to fly between first char matches.
2005-02-20 09:54:53 +00:00
Raymond Hettinger 7cbf1bcb3e * Beef-up testing of str.__contains__() and str.find().
* Speed-up "x in y" where x has more than one character.

The existing code made excessive calls to the expensive memcmp() function.
The new code uses memchr() to rapidly find a start point for memcmp().
In addition to knowing that the first character is a match, the new code
also checks that the last character is a match.  This significantly reduces
the incidence of false starts (saving memcmp() calls and making quadratic
behavior less likely).

Improves the timings on:
    python -m timeit -r7 -s"x='a'*1000" "'ab' in x"
    python -m timeit -r7 -s"x='a'*1000" "'bc' in x"

Once this code has proven itself, then string_find_internal() should refer
to it rather than running its own version.  Also, something similar may
apply to unicode objects.
