Tim Peters f47b1cd839 Whitespace normalization. 2006-05-24 20:29:44 +00:00
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.

Fredrik Lundh 347ee277aa needforspeed: refactored the replace code slightly; special-case 
constant-length changes; use fastsearch to locate the first match.

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.

Tim Peters 1bddfb84ee test_struct grew weird behavior under regrtest.py -R, 
due to a module-level cache.  Clearing the cache should
make it stop showing up in refleak reports.

Tim Peters b713ec2531 Bug #1334662 / patch #1335972: int(string, base) wrong answers. 
In rare cases of strings specifying true values near sys.maxint,
and oddball bases (not decimal or a power of 2), int(string, base)
could deliver insane answers.  This repairs all such problems, and
also speeds string->int significantly.  On my box, here are %
speedups for decimal strings of various lengths:

length speedup
------ -------
 1       12.4%
 2       15.7%
 3       20.6%
 4       28.1%
 5       33.2%
 6       37.5%
 7       41.9%
 8       46.3%
 9       51.2%
10       19.5%
11       19.9%
12       23.9%
13       23.7%
14       23.3%
15       24.9%
16       25.3%
17       28.3%
18       27.9%
19       35.7%

Note that the difference between 9 and 10 is the difference between
short and long Python ints on a 32-bit box.  The patch doesn't
actually do anything to speed conversion to long:  the speedup is
due to detecting "unsigned long" overflow more quickly.

This is a bugfix candidate, but it's a non-trivial patch and it
would be painful to separate the "bug fix" from the "speed up" parts.
 2006-05-23 18:45:30 +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... ;-)

Andrew M. Kuchling 3e134a5960 Use 'speed' instead of 'performance', because I agree with the argument 
at http://zestyping.livejournal.com/193260.html that 'erformance' really means
something more general.

Ronald Oussoren b02daf794b Patch #1488098. 
This patchs makes it possible to create a universal build on OSX 10.4 and use
the result to build extensions on 10.3. It also makes it possible to override
the '-arch' and '-isysroot' compiler arguments for specific extensions.
 2006-05-23 12:01:11 +00:00
Ronald Oussoren 58f8eba372 Disable linking extensions with -lpython2.5 for darwin. This should fix bug 
#1487105.

Georg Brandl 658d513328 PyErr_NewException now accepts a tuple of base classes as its

Richard Jones 7c88dcc5ab Merge from rjones-funccall branch. 
Applied patch zombie-frames-2.diff from sf patch 876206 with updates for
Python 2.5 and also modified to retain the free_list to avoid the 67%
slow-down in pybench recursion test. 5% speed up in function call pybench.

Fredrik Lundh 833bf9422e needforspeed: fixed unicode "in" operator to use same implementation 
approach as find/index

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.
