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

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.
 2006-05-26 18:24:15 +00:00
Fredrik Lundh b3167cbcd7 needforspeed: added rpartition implementation 2006-05-26 18:15:38 +00:00
Fredrik Lundh b947948c61 needforspeed: stringlib refactoring (in progress) 2006-05-26 17:22:38 +00:00
Fredrik Lundh a50d201bd9 needforspeed: stringlib refactoring (in progress) 2006-05-26 17:04:58 +00:00
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.
 2006-05-25 18:03:25 +00:00
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... ;-)
 2006-05-23 18:44:25 +00:00
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
 2006-05-22 15:35:12 +00:00
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.
 2006-04-14 09:08:42 +00:00
Martin v. Löwis f15da6995b Remove another INT_MAX limitation 2006-04-13 07:24:50 +00:00
Martin v. Löwis 412fb67368 Change more ints to Py_ssize_t. 2006-04-13 06:34:32 +00:00
Martin v. Löwis 80d2e591d5 Revert 34153: Py_UNICODE should not be signed. 2006-04-13 06:06:08 +00:00
Anthony Baxter ac6bd46d5c spread the extern "C" { } magic pixie dust around. Python itself builds now 
using a C++ compiler. Still lots and lots of errors in the modules built by
setup.py, and a bunch of warnings from g++ in the core.
 2006-04-13 02:06:09 +00:00
Anthony Baxter a62862120d More low-hanging fruit. Still need to re-arrange some code (or find a better 
solution) in the same way as listobject.c got changed. Hoping for a better
solution.

Georg Brandl ecdc0a9f46 That one was a mistake. 2006-03-30 12:19:07 +00:00
