Guido van Rossum 01dbc109a8 Improve performance of built-in any()/all() by avoiding PyIter_Next() -- 
using a trick found in ifilter().
Feel free to backport to 2.5.

Georg Brandl 30b78048a6 Fix refleak introduced in r59576. 2007-12-20 21:03:02 +00:00
Guido van Rossum e9a0e885db Patch #1672 by Joseph Armbruster. Use tempdir() to get a temporary directory. 2007-12-20 17:28:10 +00:00
Brett Cannon 905c31c73d Add tests for the warnings module; specifically formatwarning and showwarning. 
Still need tests for warn_explicit and simplefilter.

Guido van Rossum 0b7b6fdff3 Patch #1549 by Thomas Herve. 
This changes the rules for when __hash__ is inherited slightly,
by allowing it to be inherited when one or more of __lt__, __le__,
__gt__, __ge__ are overridden, as long as __eq__ and __ne__ aren't.

Raymond Hettinger 70fcfd03bc Bigger range for non-extended opargs. 2007-12-19 22:14:34 +00:00
Guido van Rossum 02de8979cc Patch #1583 by Adam Olsen. 
This adds signal.set_wakeup_fd(fd) which sets a file descriptor to
which a zero byte will be written whenever a C exception handler runs.

I added a simple C API as well, PySignal_SetWakeupFd(fd).

Raymond Hettinger 85dfcf3530 Users demand iterable input for named tuples. The author capitulates. 2007-12-18 23:51:15 +00:00
Christian Heimes 0a8143f646 Applied patch #1635: Float patch for inf and nan on Windows (and other platforms). 
The patch unifies float("inf") and repr(float("inf")) on all platforms.

Raymond Hettinger 8777bcae27 Simplify and speedup _asdict() for named tuples. 2007-12-18 22:21:27 +00:00
Christian Heimes 0423698bc3 Fixed #1649: IDLE error: dictionary changed size during iteration 2007-12-18 21:56:09 +00:00
Raymond Hettinger fd7ed407d7 Give meaning to the oparg for BUILD_MAP: estimated size of the dictionary. 
Allows dictionaries to be pre-sized (upto 255 elements) saving time lost
to re-sizes with their attendant mallocs and re-insertions.

Has zero effect on small dictionaries (5 elements or fewer), a slight
benefit for dicts upto 22 elements (because they had to resize once
anyway), and more benefit for dicts upto 255 elements (saving multiple
resizes during the build-up and reducing the number of collisions on
the first insertions).  Beyond 255 elements, there is no addional benefit.

Guido van Rossum 3c887b2802 Issue #1645 by Alberto Bertogli. Fix a comment. 2007-12-18 20:10:42 +00:00
Thomas Heller 153038efa4 Issue #1642: Fix segfault in ctypes when trying to delete attributes. 2007-12-18 19:00:34 +00:00
Raymond Hettinger effde12f5f Speed-up dictionary constructor by about 10%. 
New opcode, STORE_MAP saves the compiler from awkward stack manipulations
and specializes for dicts using PyDict_SetItem instead of PyObject_SetItem.

Old disassembly:
              0 BUILD_MAP                0
              3 DUP_TOP
              4 LOAD_CONST               1 (1)
              7 ROT_TWO
              8 LOAD_CONST               2 ('x')
             11 STORE_SUBSCR
             12 DUP_TOP
             13 LOAD_CONST               3 (2)
             16 ROT_TWO
             17 LOAD_CONST               4 ('y')
             20 STORE_SUBSCR

New disassembly:
              0 BUILD_MAP                0
              3 LOAD_CONST               1 (1)
              6 LOAD_CONST               2 ('x')
              9 STORE_MAP
             10 LOAD_CONST               3 (2)
             13 LOAD_CONST               4 ('y')
             16 STORE_MAP

Christian Heimes bb89992211 Make it a bit easier to test Tcl/Tk and idle from a build dir. 2007-12-18 09:00:13 +00:00
Christian Heimes 8affb5f236 Fixed for #1601: IDLE not working correctly on Windows (Py30a2/IDLE30a1) 
Amaury's ideas works great. Should we build the Python core with WINVER=0x0500 and _WIN32_WINNT=0x0500, too?
 2007-12-18 03:38:03 +00:00
Raymond Hettinger 88880b2dd6 Add more namedtuple() test cases. Neaten the code and comments. 2007-12-18 00:13:45 +00:00
Facundo Batista e64acfad3d Removed the private _rounding_decision: it was not needed, and the code 
is now simpler.  Thanks Mark Dickinson.

Raymond Hettinger 6c87af5d87 Optimize PyList_AsTuple(). Improve cache performance by doing the 
pointer copy and object increment in one pass.  For small lists,
save the overhead of the call to memcpy() -- this comes up in
calls like f(*listcomp).
