Mark Dickinson 1ec2fcd16e Issue #3004: Minor fix to slice.indices(). slice(-10).indices(9) now
returns (0, 0, 1) instead of (0, -1, 1), and slice(None, 10, -1).indices(10)
returns (9, 9, -1) instead of (9, 10, -1).

Amaury Forgeot d'Arc a8919fe631 Issue 3110: Crash with weakref subclass,
seen after a "import multiprocessing.reduction"

An instance of a weakref subclass can have attributes.
If such a weakref holds the only strong reference to the object,
deleting the weakref will delete the object. In this case,
the callback must not be called, because the ref object is being deleted!

Gregory P. Smith 9d53457e59 Merge in release25-maint r60793:
Added checks for integer overflows, contributed by Google. Some are

Gregory P. Smith 99a3dce92d More reverting of r63675 per the mailing list discussions. This restores
occurances of PyBytes_ in the code to their original PyString_ names.  The
bytesobject.c file will be renamed back to stringobject.c in a future checkin.

Gregory P. Smith dd96db63f6 This reverts r63675 based on the discussion in this thread:
http://mail.python.org/pipermail/python-dev/2008-June/079988.html

Python 2.6 should stick with PyString_* in its codebase.  The PyBytes_* names
in the spirit of 3.0 are available via a #define only.  See the email thread.

Georg Brandl ecbbd94e71 #2809 followup: even better split docstring. 2008-05-11 20:53:55 +00:00
Eric Smith cf537ff39e Addresses issue 2802: 'n' formatting for integers.
Adds 'n' as a format specifier for integers, to mirror the same
specifier which is already available for floats.  'n' is the same as
'd', but inserts the current locale-specific thousands grouping.

I added this as a stringlib function, but it's only used by str type,
not unicode.  This is because of an implementation detail in
unicode.format(), which does its own str->unicode conversion.  But the
unicode version will be needed in 3.0, and it may be needed by other
code eventually in 2.6 (maybe decimal?), so I left it as a stringlib
implementation.  As long as the unicode version isn't instantiated,
there's no overhead for this.

Alexandre Vassalotti 9510e4a9f8 Added module stub for copy_reg renaming in 3.0.
Renamed copy_reg to copyreg in the standard library, to avoid
spurious warnings and ease later merging to py3k branch. Public

Christian Heimes 6f34109384 I finally got the time to update and merge Mark's and my trunk-math branch. The patch is collaborated work of Mark Dickinson and me. It was mostly done a few months ago. The patch fixes a lot of loose ends and edge cases related to operations with NaN, INF, very small values and complex math.
The patch also adds acosh, asinh, atanh, log1p and copysign to all platforms. Finally it fixes differences between platforms like different results or exceptions for edge cases. Have fun :)

Martin v. Löwis d918e4e068 Bug #2388: Fix gcc warnings when compiling with --enable-unicode=ucs4. 2008-04-07 03:08:28 +00:00
Gregory P. Smith aa63d0d4af Make file objects as thread safe as the underlying libc FILE* implementation.
close() will now raise an IOError if any operations on the file object
are currently in progress in other threads.

Most code was written by Antoine Pitrou (pitrou).  Additional testing,
documentation and test suite cleanup done by me (gregory.p.smith).

Fixes issue 815646 and 595601 (as well as many other bugs and
references to this problem dating back to the dawn of Python).

Neal Norwitz d183bdd6fb Revert r61969 which added casts to Py_CHARMASK to avoid compiler warnings.
Rather than sprinkle casts throughout the code, change Py_CHARMASK to
always cast it's result to an unsigned char.  This should ensure we
do the right thing when accessing an array with the result.

Mark Dickinson c23b8a7af9 Issue 705836: Fix struct.pack(">f", 1e40) to behave consistently
across platforms:  it should now raise OverflowError on all
platforms.  (Previously it raised OverflowError only on
non IEEE 754 platforms.)

Also fix the (already existing) test for this behaviour
so that it actually raises TestFailed instead of just
referencing it.

Jeffrey Yasskin 960b9b7a2f Move abc._Abstract into object by adding a new flag Py_TPFLAGS_IS_ABSTRACT,
which forbids constructing types that have it set. The effect is to speed

  ./python.exe -m timeit -s 'import abc' -s 'class Foo(object): __metaclass__ = abc.ABCMeta' 'Foo()'

up from 2.5us to 0.201us. This fixes issue 1762.

Eric Smith bc32fee029 Added code to correct combining str and unicode in ''.format(). Added test case. 2008-02-18 18:02:34 +00:00
Eric Smith a9f7d62480 Backport of PEP 3101, Advanced String Formatting, from py3k.
Highlights:
 - Adding PyObject_Format.
 - Adding string.Format class.
 - Adding __format__ for str, unicode, int, long, float, datetime.
 - Adding builtin format.
 - Adding ''.format and u''.format.
 - str/unicode fixups for formatters.

The files in Objects/stringlib that implement PEP 3101 (stringdefs.h,
unicodedefs.h, formatter.h, string_format.h) are identical in trunk
and py3k.  Any changes from here on should be made to trunk, and
changes will propogate to py3k).

Eric Smith 3f91437e5f In PyNumber_ToBase, changed from an assert to returning an error when PyObject_Index() returns something other than an int or long. It should never be possible to trigger this, as PyObject_Index checks to make sure it returns an int or long. 2008-02-15 12:14:32 +00:00
Christian Heimes 2f0da53d28 Fixed repr() and str() of complex numbers. Complex suffered from the same problem as floats but I forgot to test and fix them. 2008-02-15 06:57:08 +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.

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 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

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

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

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.

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.)

2007-09-30 20:37:19 +00:00
Brett Cannon 0b14f243c4 tuple.__repr__ did not consider a reference loop as it is not possible from
Python code; but it is possible from C.  object.__str__ had the issue of not
expecting a type to doing something within it's tp_str implementation that
could trigger an infinite recursion, but it could in C code..  Both found
thanks to BaseException and how it handles its repr.

Closes issue #1686386.  Thanks to Thomas Herve for taking an initial stab at
coming up with a solution.

Facundo Batista d544df7ddd Issue #1772851. Alters long.__hash__ from being *almost* completely

int, and also unchanged for the vast majority of long integers n of
reasonable size.

Guido van Rossum b55911378f Patch # 1026 by Benjamin Aranguren (with Alex Martelli):
Backport abc.py and isinstance/issubclass overloading to 2.6.

I had to backport test_typechecks.py myself, and make one small change
to abc.py to avoid duplicate work when x.__class__ and type(x) are the
same.

Brett Cannon 1e534b5425 Fix a crasher where Python code managed to infinitely recurse in C code without
ever going back out to Python code in PyObject_Call().  Required introducing a
static RuntimeError instance so that normalizing an exception there is no
reliance on a recursive call that would put the exception system over the
recursion check itself.

Thomas Wouters 3ccec68a05 Improve extended slicing support in builtin types and classes. Specifically:
- Specialcase extended slices that amount to a shallow copy the same way as
   is done for simple slices, in the tuple, string and unicode case.

 - Specialcase step-1 extended slices to optimize the common case for all
   involved types.

 - For lists, allow extended slice assignment of differing lengths as long
   as the step is 1. (Previously, 'l[:2:1] = []' failed even though
   'l[:2] = []' and 'l[:2:None] = []' do not.)

 - Implement extended slicing for buffer, array, structseq, mmap and
   UserString.UserString.

 - Implement slice-object support (but not non-step-1 slice assignment) for
   UserString.MutableString.

 - Add tests for all new functionality.

Kristján Valur Jónsson f030394de3 Fix problems in x64 build that were discovered by the testsuite:
- Reenable modules on x64 that had been disabled aeons ago for Itanium.
- Cleared up confusion about compilers for 64 bit windows.  There is only Itanium and x64.  Added macros MS_WINI64 and MS_WINX64 for those rare cases where it matters, such as the disabling of modules above.
- Set target platform (_WIN32_WINNT and WINVER) to 0x0501 (XP) for x64, and 0x0400 (NT 4.0) otherwise, which are the targeted minimum platforms.
- Fixed thread_nt.h.  The emulated InterlockedCompareExchange function didn´t work on x64, probaby due to the lack of a "volatile" specifier.  Anyway, win95 is no longer a target platform.
- Itertools module used wrong constant to check for overflow in count()
- PyInt_AsSsize_t couldn't deal with attribute error when accessing the __long__ member.
- PyLong_FromSsize_t() incorrectly specified that the operand were unsigned.

With these changes, the x64 passes the testsuite, for those modules present.

Guido van Rossum f102e24bd3 Add a type.__init__() method that enforces the same signature as
type.__new__(), and then calls object.__init__(cls), just to be anal.

This allows us to restore the code in string.py's _TemplateMetaclass
that called super(...).__init__(name, bases, dct), which I commented
out yesterday since it broke due to the stricter argument checking
added to object.__init__().
2007-03-23 18:53:03 +00:00
Guido van Rossum 143b564059 - Bug #1683368: The object.__init__() and object.__new__() methods are
now stricter in rejecting excess arguments.  The only time when
  either allows excess arguments is when it is not overridden and the
  other one is.  For backwards compatibility, when both are
  overridden, it is a deprecation warning (for now; maybe a Py3k
  warning later).

When merging this into 3.0, the warnings should become errors.

Note: without the change to string.py, lots of spurious warnings happen.
What's going on there?
