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.

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.

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

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 ;-)

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.

b552c4d848 Code had returned an ssize_t, upcast to long, then converted with PyInt_FromLong. 
Now using PyInt_FromSsize_t.

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.

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.

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... ;-)

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).
