Christian Heimes e93237dfcc #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE and Py_REFCNT. Macros for b/w compatibility are available. 2007-12-19 02:37:44 +00:00
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.

Thomas Wouters 9e398cac94 Fix SF bug #1545837: array.array borks on deepcopy.
array.__deepcopy__() needs to take an argument, even if it doesn't actually
use it. Will backport to 2.5 and 2.4 (if applicable.)

Neal Norwitz 8a87f5d37e Patch #1538606, Patch to fix __index__() clipping.
I modified this patch some by fixing style, some error checking, and adding
XXX comments.  This patch requires review and some changes are to be expected.
I'm checking in now to get the greatest possible review and establish a
baseline for moving forward.  I don't want this to hold up release if possible.

Neal Norwitz 6f5ff3f3eb Klocwork made another run and found a bunch more problems.
This is the first batch of fixes that should be easy to verify based on context.

This fixes problem numbers: 220 (ast), 323-324 (symtable),
321-322 (structseq), 215 (array), 210 (hotshot), 182 (codecs), 209 (etree).

- provide dummies for getenv, environ, and GetVersion
- adjust MSC_VER check in socketmodule.c

Brett Cannon de3b052216 Buffer objects would return the read or write buffer for a wrapped object when
the char buffer was requested.  Now it actually returns the char buffer if
available or raises a TypeError if it isn't (as is raised for the other buffer
types if they are not present but requested).

Not a backport candidate since it does change semantics of the buffer object
(although it could be argued this is enough of a bug to bother backporting).

Martin Blais 2856e5f390 Support for buffer protocol for socket and struct.
* Added socket.recv_buf() and socket.recvfrom_buf() methods, that use the buffer
  protocol (send and sendto already did).

* Added struct.pack_to(), that is the corresponding buffer compatible method to
  unpack_from().

* Fixed minor typos in arraymodule.

Skip Montanaro cbe2e491bc C++ compiler cleanup: a cast here, a cast there... still does not compile under C++ though... 2006-04-18 19:39:48 +00:00
Thomas Wouters c6e55068ca Use Py_VISIT in all tp_traverse methods, instead of traversing manually or
using a custom, nearly-identical macro. This probably changes how some of
these functions are compiled, which may result in fractionally slower (or
faster) execution. Considering the nature of traversal, visiting much of the
address space in unpredictable patterns, I'd argue the code readability and
maintainability is well worth it ;P

Raymond Hettinger 49f9bd15ff SF feature request #686323: Minor array module enhancements
array.extend() now accepts iterable arguments implements as a series
of appends.  Besides being a user convenience and matching the behavior
for lists, this the saves memory and cycles that would be used to
create a temporary array object.
2004-03-14 05:43:59 +00:00
Raymond Hettinger 6e2ee866fa Update the array overallocation scheme to match the approach used for
lists.  Speeds append() operations and reduces memory requirements
(because of more conservative overallocation).

Paves the way for the feature request for array.extend() to support
arbitrary iterable arguments.

Raymond Hettinger 85004cc47d SF bug #782369: Massive memory leak in array module
Fixed leak caused by switching from PyList_GetItem to PySequence_GetItem.
Added missing NULL check.
Clarified code by converting an "if" to an "else if".

Will backport to 2.3.

Walter Dörwald 8bb1ae9c34 All calls to getarrayitem() (which is static) are done either in loops
over the size of the array, or the callers check the index bounds themselves,
so the index check never failed => Replace it with an assert().
2003-05-23 10:01:07 +00:00
Walter Dörwald 9e46abed50 Fix array.array.insert(), so that it treats negative indices as
being relative to the end of the array, just like list.insert() does.
This closes SF bug #739313.

Raymond Hettinger 88ba1e39ec SF Patch 685051: fix for 680789: reprs in arraymodule
(contributed by logistix; substantially reworked by rhettinger).

To create a representation of non-string arrays, array_repr() was
starting with a base Python string object and repeatedly using +=
to concatenate the representation of individual objects.

Logistix had the idea to convert to an intermediate tuple form and
then join it all at once.  I took advantage of existing tools and
formed a list with array_tolist() and got its representation through
PyObject_Repr(v) which already has a fast implementation for lists.

Raymond Hettinger 1da1dbf458 Renamed PyObject_GenericGetIter to PyObject_SelfIter

Jason Tishler fb8595df4f Patch #661760: Cygwin auto-import module patch
The attached patch enables shared extension
modules to build cleanly under Cygwin without
moving the static initialization of certain function
pointers (i.e., ones exported from the Python
DLL core) to a module initialization function.

Additionally, this patch fixes the modules that
have been changed in the past to accommodate
Cygwin.

Tim Peters 0c32279626 Removed more stray instances of statichere, but left _sre.c alone. 2002-07-17 16:49:03 +00:00
Jeremy Hylton 938ace69a0 staticforward bites the dust.
The staticforward define was needed to support certain broken C
compilers (notably SCO ODT 3.0, perhaps early AIX as well) botched the
static keyword when it was used with a forward declaration of a static
initialized structure.  Standard C allows the forward declaration with
static, and we've decided to stop catering to broken C compilers.  (In
fact, we expect that the compilers are all fixed eight years later.)

I'm leaving staticforward and statichere defined in object.h as
static.  This is only for backwards compatibility with C extensions
that might still use it.

XXX I haven't updated the documentation.

Michael W. Hudson 9c14badc5f Fix the bug described in

already checked in but obviously not.
