Neal Norwitz 29a5fdb7ca Fix str.rpartition(sep) when sep is not found in str. 
Partially from SF patch #1551339, but also taken from head.

Neal Norwitz 19c35bba5d - Patch #1541585: fix buffer overrun when performing repr() on 
a unicode string in a build with wide unicode (UCS-4) support.

I will forward port to 2.6.  Can someone backport to 2.4?

Marc-André Lemburg 3a457790c7 Correct an accidentally removed previous patch. 2006-08-14 12:57:27 +00:00
Marc-André Lemburg 040f76b79c Slightly revised version of patch #1538956: 
Replace UnicodeDecodeErrors raised during == and !=
compares of Unicode and other objects with a new
UnicodeWarning.

All other comparisons continue to raise exceptions.
Exceptions other than UnicodeDecodeErrors are also left
untouched.

Neal Norwitz 8a87f5d37e Patch #1538606, Patch to fix __index__() clipping. 
I modified this patch some by fixing style, some error checking, and adding
XXX comments.  This patch requires review and some changes are to be expected.
I'm checking in now to get the greatest possible review and establish a
baseline for moving forward.  I don't want this to hold up release if possible.

Neal Norwitz e1fdb32ff2 Handle allocation failures gracefully. Found with failmalloc. 
Many (all?) of these could be backported.

Fredrik Lundh c2d29c5a6d needforspeed: replace improvements, changed to Py_LOCAL_INLINE

Fredrik Lundh e6e43c867d needforspeed: stringlib refactoring: use stringlib/find for string find 2006-05-26 19:48:07 +00:00
Fredrik Lundh c816281304 needforspeed: use a macro to fix slice indexes 2006-05-26 19:33:03 +00:00
Fredrik Lundh ce4eccb0c4 needforspeed: stringlib refactoring: use stringlib/find for unicode 
find
 2006-05-26 19:29:05 +00:00
Fredrik Lundh 58b5e84d52 needforspeed: stringlib refactoring, continued. added count and 
find helpers; updated unicodeobject to use stringlib_count
 2006-05-26 19:24:53 +00:00
Fredrik Lundh 9c0e9c089c needspeed: rpartition documentation, tests, and a bug fixes. 
feel free to add more tests and improve the documentation.

Fredrik Lundh 95e2a91615 use Py_LOCAL also for string and unicode objects 2006-05-26 11:38:15 +00:00
Fredrik Lundh f2c0dfdb13 needforspeed: use Py_ssize_t for the fastsearch counter and skip 
length (thanks, neal!).  and yes, I've verified that this doesn't
slow things down ;-)
 2006-05-26 10:27:17 +00:00
Fredrik Lundh 450277fef5 needforspeed: use METH_O for argument handling, which made partition some 
~15% faster for the current tests (which is noticable faster than a corre-
sponding find call).  thanks to neal-who-never-sleeps for the tip.
 2006-05-26 09:46:59 +00:00
Fredrik Lundh 06a69dd8ff needforspeed: partition implementation, part two. 
feel free to improve the documentation and the docstrings.
 2006-05-26 08:54:28 +00:00
Andrew Dalke b552c4d848 Code had returned an ssize_t, upcast to long, then converted with PyInt_FromLong. 
Now using PyInt_FromSsize_t.

Fredrik Lundh 0c71f88fc9 needforspeed: check for overflow in replace (from Andrew Dalke) 2006-05-25 16:46:54 +00:00
Fredrik Lundh 347ee277aa needforspeed: refactored the replace code slightly; special-case 
constant-length changes; use fastsearch to locate the first match.
 2006-05-24 16:35:18 +00:00
Fredrik Lundh d5e0dc51cf needforspeedindeed: use fastsearch also for __contains__ 2006-05-24 15:11:01 +00:00
Fredrik Lundh 6471ee4f18 needforspeed: use "fastsearch" for count and findstring helpers. this 
results in a 2.5x speedup on the stringbench count tests, and a 20x (!)
speedup on the stringbench search/find/contains test, compared to 2.5a2.

for more on the algorithm, see:

    http://effbot.org/zone/stringlib.htm

if you get weird results, you can disable the new algoritm by undefining
USE_FAST in Objects/unicodeobject.c.

Fredrik Lundh 240bf2a8e4 use Py_ssize_t for string indexes (thanks, neal!) 2006-05-24 10:20:36 +00:00
Fredrik Lundh 7763351808 return 0 on misses, not -1. 2006-05-23 19:47:35 +00:00
Fredrik Lundh b63588c188 needforspeed: use append+reverse for rsplit, use "bloom filters" to 
speed up splitlines and strip with charsets; etc.  rsplit is now as
fast as split in all our tests (reverse takes no time at all), and
splitlines() is nearly as fast as a plain split("\n") in our tests.
and we're not done yet... ;-)

Fredrik Lundh 833bf9422e needforspeed: fixed unicode "in" operator to use same implementation 
approach as find/index
 2006-05-23 10:12:21 +00:00
Tim Peters 1bacc641a0 unicode_repeat(): Change type of local to Py_ssize_t, 
since that's what it should be.
 2006-05-23 05:47:16 +00:00
Tim Peters 286085c781 PyUnicode_Join(): Recent code changes introduced new 
compiler warnings on Windows (signed vs unsigned mismatch
in comparisons).  Cleaned that up by switching more locals
to Py_ssize_t.  Simplified overflow checking (it can _be_
simpler because while these things are declared as
Py_ssize_t, then should in fact never be negative).
 2006-05-22 19:17:04 +00:00
Fredrik Lundh 8a8e05a2b9 needforspeed: use memcpy for "long" strings; use a better algorithm 
for long repeats.
 2006-05-22 17:12:58 +00:00
Fredrik Lundh f1d60a5384 needforspeed: speed up unicode repeat, unicode string copy 2006-05-22 16:29:30 +00:00
Fredrik Lundh 763b50f9d9 docstring tweaks: count counts non-overlapping substrings, not 
total number of occurences

Neal Norwitz 1004a5339a Patch #1488312, Fix memory alignment problem on SPARC in unicode. Will backport 2006-05-15 07:17:23 +00:00
Thomas Wouters 715a4cdea2 Use %zd instead of %i as format character (in call to PyErr_Format) for 
Py_ssize_t argument.
 2006-04-16 22:04:49 +00:00
Martin v. Löwis 5cb6936672 Make Py_BuildValue, PyObject_CallFunction and 
PyObject_CallMethod aware of PY_SSIZE_T_CLEAN.
