Christian Heimes e247f0037f Use a static and interned string for __subclasscheck__ and __instancecheck__ as suggested by Thomas Heller in #2115 2008-02-14 22:40:11 +00:00
Christian Heimes 3b718a79af Implemented Martin's suggestion to clear the free lists during the garbage collection of the highest generation. 2008-02-14 12:47:33 +00:00
Raymond Hettinger a37430a0ce dict.copy() rises from the ashes. Revert r60687. 2008-02-12 19:05:36 +00:00
Eric Smith 5e527ebee1 Added PyNumber_ToBase and supporting routines _PyInt_Format and
_PyLong_Format.  In longobject.c, changed long_format to
_PyLong_Format.  In intobject.c, changed uses of PyOS_snprintf to
_PyInt_Format instead.

_PyLong_Format is similar to py3k's routine of the same name, except
it has 2 additional parameters: addL and newstyle.  addL was existing
in long_format, and controls adding the trailing "L".  This is
unneeded in py3k.  newstyle is used to control whether octal prepends
"0" (the pre-2.6 style), or "0o" (the 3.0 sytle).

PyNumber_ToBase is needed for PEP 3127 (Integer Literal Support and
Syntax) and PEP 3101 (Advanced String Formatting).

This changeset does not need merging into py3k.

Christian Heimes f75dbef208 Deallocate content of the dict free list on interpreter shutdown 2008-02-08 00:11:31 +00:00
Christian Heimes b4ee4a16f4 Added some statistics code to dict and list object code. I wanted to test how a larger freelist affects the reusage of freed objects. Contrary to my gut feelings 80 objects is more than fine for small apps. I haven't profiled a large app yet. 2008-02-07 17:15:30 +00:00
Raymond Hettinger 55285ef44c Return ints instead of longs for tuple.count() and tuple.index(). 2008-02-07 02:12:52 +00:00
Raymond Hettinger 5b07ebce86 Issue 2025: Add tuple.count() and tuple.index() to follow the ABC in collections.Sequence. 2008-02-07 00:54:20 +00:00
Christian Heimes 5b970ad483 Unified naming convention for free lists and their limits. All free lists
in Object/ are named ``free_list``, the counter ``numfree`` and the upper
limit is a macro ``PyName_MAXFREELIST`` inside an #ifndef block.

The chances should make it easier to adjust Python for platforms with
less memory, e.g. mobile phones.

Christian Heimes 6075a82243 Limit free list of method and builtin function objects to 256 entries each. 2008-02-06 12:44:34 +00:00
Christian Heimes 422051a367 Patch #1953
I implemented the function sys._compact_freelists() and C API functions PyInt_/PyFloat_CompactFreeList() to compact the pre-allocated blocks of ints and floats. They allow the user to reduce the memory usage of a Python process that deals with lots of numbers.
The patch also renames sys._cleartypecache to sys._clear_type_cache

Amaury Forgeot d'Arc cab3d98ca1 Ensure that PySet_Add() operates on a newly created frozenset, like PyTuple_SetItem does.
Add PyFrozenSet_Check(), which was not needed before; The list of Py*Set_Check* macros seems to be complete now.

Add missing NEWS entries about all this.

careful when looking over it.

Christian Heimes 7f39c9fcbb Backport of several functions from Python 3.0 to 2.6 including PyUnicode_FromString, PyUnicode_Format and PyLong_From/AsSsize_t. The functions are partly required for the backport of the bytearray type and _fileio module. They should also make it easier to port C to 3.0.
First chapter of the Python 3.0 io framework back port: _fileio
The next step depends on a working bytearray type which itself depends on a backport of the nwe buffer API.

Neal Norwitz 5f95a79b2b Add prototypes to get the mathmodule.c to compile on OSF1 5.1 (Tru64)

Christian Heimes c3b2a4afe8 Added more comments to the new structseq repr code and implemented several of Neal's suggestions. 2008-01-14 06:06:19 +00:00
Christian Heimes c94e2b5c12 Now that I've learnt about structseq objects I felt like converting sys.float_info to a structseq. It's

Georg Brandl dfe5dc8455 Make Python compile with --disable-unicode. 2008-01-07 18:16:36 +00:00
Jeffrey Yasskin 9871d8fe22 Continue rolling back pep-3141 changes that changed behavior from 2.5. This
round included:
 * Revert round to its 2.6 behavior (half away from 0).
 * Because round, floor, and ceil always return float again, it's no
   longer necessary to have them delegate to __xxx___, so I've ripped
   that out of their implementations and the Real ABC. This also helps
   in implementing types that work in both 2.6 and 3.0: you return int
   from the __xxx__ methods, and let it get enabled by the version
   upgrade.
 * Make pow(-1, .5) raise a ValueError again.
2008-01-05 08:47:13 +00:00
Jeffrey Yasskin 737c73f96f Make math.{floor,ceil}({int,long}) return float again for backwards

Christian Heimes 000a074c95 Modified PyImport_Import and PyImport_ImportModule to always use absolute imports by calling __import__ with an explicit level of 0
Added a new API function PyImport_ImportModuleNoBlock. It solves the problem with dead locks when mixing threads and imports
2008-01-03 22:16:32 +00:00
Jeffrey Yasskin 2f3c16be73 Backport PEP 3141 from the py3k branch to the trunk. This includes r50877 (just
the complex_pow part), r56649, r56652, r56715, r57296, r57302, r57359, r57361,
r57372, r57738, r57739, r58017, r58039, r58040, and r59390, and new
documentation. The only significant difference is that round(x) returns a float
to preserve backward-compatibility. See http://bugs.python.org/issue1689.

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.

Christian Heimes 0a8143f646 Applied patch #1635: Float patch for inf and nan on Windows (and other platforms).

2007-12-18 23:22:54 +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.
2007-12-18 21:24:09 +00:00
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).
2007-12-15 00:07:25 +00:00
Christian Heimes 90e10e79ea Fixed bug #1620: New @spam.getter property syntax modifies the property in place.
I added also the feature that a @prop.getter decorator does not overwrite the doc string of the property if it was given as an argument to property().
2007-12-14 02:35:23 +00:00
Christian Heimes f15c66e143 The new float repr causes too much trouble and pain. I'm disabling the feature until we have sorted out the issues on all machines. 64bit machines seem to have issues and Guido has reported even worse.
Guido: It's pretty bad actually -- repr(1e5) comes out as '1.0'... Ditto for
repr(1eN) for most N... Both in 2.6 and in 3.0...
2007-12-11 00:54:34 +00:00
Christian Heimes 284d927625 Backport of r59456:59458 from py3k to trunk
Issue #1580: New free format floating point representation based on "Floating-Point Printer Sample Code", by Robert G. Burger. For example repr(11./5) now returns '2.2' instead of '2.2000000000000002'.

Thanks to noam for the patch! I had to modify doubledigits.c slightly to support X64 and IA64 machines on Windows. I also added the new file to the three project files.

Christian Heimes e8954f8ce7 Backport of the PCbuild9 directory from the py3k branch.
I've finished the last task for the PCbuild9 directory today. I don't think there is much left to do. Now you can all play around with the shiny new VS 2008 and try the PGO builds. I was able to get a speed improvement of about 10% on py3k.

Amaury Forgeot d'Arc 5087980c1e The incremental decoder for utf-7 must preserve its state between calls.

Facundo Batista 292a069b88 Fix for stupid error (I need to remember to do a full 'make clean + make'
cycle before the tests...). Sorry.
2007-11-16 18:41:24 +00:00
Facundo Batista 57d5669f4b Now in find, rfind, index, and rindex, you can use None as defaults,
as usual with slicing (both with str and unicode strings).  This
fixes issue 1259.

For str only the stringobject.c file was modified.  But for unicode,
I needed to repeat in the four functions a lot of code, so created
a new function that does part of the job for them (and placed it in
find.h, following a suggestion of Barry).

Also added tests for this behaviour.

Guido van Rossum 9b847b432c Add missing "return NULL" in overflow check in PyObject_Repr(). 2007-11-06 23:32:56 +00:00
Guido van Rossum 1c1ac38157 Backport fixes for the code that decodes octal escapes (and for PyString
also hex escapes) -- this was reaching beyond the end of the input string
buffer, even though it is not supposed to be \0-terminated.
This has no visible effect but is clearly the correct thing to do.
(In 3.0 it had a visible effect after removing ob_sstate from PyString.)
