Bob Ippolito fb8b84af54 Patch #1493701: performance enhancements for struct module. 2006-05-23 18:46:41 +00:00
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.

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

Fredrik Lundh 3d885e0195 needforspeed: check first *and* last character before doing a full memcmp 2006-05-23 10:10:57 +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.

Ronald Oussoren 306b1f31b7 Fix bug #1000914 (again). 
This patches a file that is generated by bgen, however the code is now the
same as a current copy of bgen would generate.  Without this patch most types
in the Carbon.CF module are unusable.

I haven't managed to coax bgen into generating a complete copy of _CFmodule.c
yet :-(, hence the manual patching.

Vinay Sajip 9e9c2528a4 Changed status from "beta" to "production"; since logging has been part of the stdlib since 2.3, it should be safe to make this assertion ;-) 2006-05-18 07:28:58 +00:00
