* More low-hanging fruit. Still need to re-arrange some code (or find a betterAnthony Baxter2006-04-111-35/+35

* Use macro versions instead of function versions when we already know the type.Neal Norwitz2006-03-201-4/+5
| | | | | | | | This will hopefully get rid of some Coverity warnings, be a hint to developers, and be marginally faster. Some asserts were added when the type is currently known, but depends on values from another function.
* Introduced symbol PY_FORMAT_SIZE_T. See the new commentsTim Peters2006-03-171-31/+22

| | | | | | This was mostly written by Travis Oliphant. I've inspected it all; Neal Norwitz and MvL have also looked at it (in an earlier incarnation).

* Add const to several API functions that take char *.Jeremy Hylton2005-12-101-1/+1
| | | | | | | | | | | | | | | | | | | In C++, it's an error to pass a string literal to a char* function without a const_cast(). Rather than require every C++ extension module to put a cast around string literals, fix the API to state the const-ness. I focused on parts of the API where people usually pass literals: PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type slots, etc. Predictably, there were a large set of functions that needed to be fixed as a result of these changes. The most pervasive change was to make the keyword args list passed to PyArg_ParseTupleAndKewords() to be a const char *kwlist[]. One cast was required as a result of the changes: A type object mallocs the memory for its tp_doc slot and later frees it. PyTypeObject says that tp_doc is const char *; but if the type was created by type_new(), we know it is safe to cast to char *.
* Fix bug:Michael W. Hudson2005-10-211-4/+0
| | | | | | | | [ 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.

* SF bug #1224347: int/long unification and hex()Raymond Hettinger2005-06-291-11/+5
| | | | Hex longs now print with lowercase letters like their int counterparts.
* * Beef-up tests for str.count().Raymond Hettinger2005-02-201-2/+7
| | | | * Speed-up str.count() by using memchr() to fly between first char matches.
* * Beef-up testing of str.__contains__() and str.find().Raymond Hettinger2005-02-201-13/+26
| | | | | | | | | | | | | | | | | | | * 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.
* More bug #1077106 stuff, sorry -- modem induced impatiece!Michael W. Hudson2005-01-311-0/+1

* SF bug #1054139: serious string hashing error in 2.4b1Raymond Hettinger2004-10-261-0/+1
| | | | | _PyString_Resize() readied strings for mutation but did not invalidate the cached hash value.
* SF Patch #1007087: Return new string for single subclass joins (Bug #1001011)Raymond Hettinger2004-08-231-12/+8
| | | | | | | (Patch contributed by Nick Coghlan.) Now joining string subtypes will always return a string. Formerly, if there were only one item, it was returned unchanged.

* Subclasses of string can no longer be interned. The semantics ofJeremy Hylton2004-08-071-22/+12
| | | | | | | | | | | interning were not clear here -- a subclass could be mutable, for example -- and had bugs. Explicitly interning a subclass of string via intern() will raise a TypeError. Internal operations that attempt to intern a string subclass will have no effect. Added a few tests to test_builtin that includes the old buggy code and verifies that calls like PyObject_SetAttr() don't fail. Perhaps these tests should have gone in test_string.

* - Removed FutureWarnings related to hex/oct literals and conversionsGuido van Rossum2003-11-291-17/+19
| | | | | | | | | | and left shifts. (Thanks to Kalle Svensson for SF patch 849227.) This addresses most of the remaining semantic changes promised by PEP 237, except for repr() of a long, which still shows the trailing 'L'. The PEP appears to promise warnings for operations that changed semantics compared to Python 2.3, but this is not implemented; we've suffered through enough warnings related to hex/oct literals and I think it's best to be silent now.

* Optimize string_repeat.Raymond Hettinger2003-01-061-2/+11
| | | | | | | | | | | Christian Tismer pointed out the high cost of the loop overhead and function call overhead for 'c' * n where n is large. Accordingly, the new code only makes lg2(n) loops. Interestingly, 'c' * 1000 * 1000 ran a bit faster with old code. At some point, the loop and function call overhead became cheaper than invalidating the cache with lengthy memcpys. But for more typical sizes of n, the new code runs much faster and for larger values of n it runs only a bit slower.
