Neal Norwitz 1ac754fa10 Check return result from Py_InitModule*(). This API can fail.
Probably should be backported.

Raymond Hettinger b0900e6a21 SF #1085304: Make array.array pickle-able 2004-12-16 16:23:40 +00:00
Raymond Hettinger 6ab78cd0c0 SF feature request #992967: array.array objects should support sequences.
Made the constructor accept general iterables.
2004-08-29 07:50:43 +00:00
Raymond Hettinger cb87bc8e7e Add weakref support to array.array and file objects. 2004-05-31 00:35:52 +00:00
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 84fc9aa6ce SF 686323: Minor array module enhancements
Allows use of tuples for the initializer.
2003-04-24 10:41:55 +00:00
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.
2003-04-23 17:27:00 +00:00
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

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.

Guido van Rossum 146483964e Patch supplied by Burton Radons for his own SF bug #487390: Modifying
type.__module__ behavior.

This adds the module name and a dot in front of the type name in every
type object initializer, except for built-in types (and those that
already had this).  Note that it touches lots of Mac modules -- I have
no way to test these but the changes look right.  Apologies if they're
not.  This also touches the weakref docs, which contains a sample type
object initializer.  It also touches the mmap test output, because the
mmap type's repr is included in that output.  It touches object.h to
put the correct description in a comment.
2001-12-08 18:02:58 +00:00

Guido van Rossum 05bbb9a8fb The array type was missing the Py_TPFLAGS_DEFAULT initializer for the
tp_flags.  This will become important when I introduce
Py_TPFLAGS_HAVE_RICHCOMPARE (as I should have!).
2001-01-24 21:44:21 +00:00
Guido van Rossum 9d19cb8a70 Same treatment as listobject.c:
- In count(), remove(), index(): call RichCompare(Py_EQ).

- Get rid of array_compare(), in favor of new array_richcompare() (a
  near clone of list_compare()).

- Aligned items in array_methods initializer and comments for type
  struct initializer.

- Folded a few long lines.

Tim Peters 7c1cb46126 Fix for SF bug 117402, crashes on str(array) and repr(array). This was an
unfortunate consequence of somebody switching from PyArg_Parse to
PyArg_ParseTuple but without changing the argument from a NULL to a tuple.

Fred Drake d5fadf75e4 Rationalize use of limits.h, moving the inclusion to Python.h.

Tim Peters 077a11dd00 arraymodule: Fix SF bug 113960.
reverse() didn't work at all due to bad arg check.
    Fixed that.
    Added Brad Chapman to ACKS file, as the proud new owner of two
        implicitly copyrighted lines of Python source code <wink>.
    Repaired buffer_info's total lack of arg-checking.
    Replaced memmove by memcpy in reverse() guts, as memmove is
        often slower and the memory areas are guaranteed disjoint.
    Replaced poke-and-hope unchecked decl of tmp buffer size by
        assert-checked larger tmp buffer.
    Got rid of inconsistent spaces before open paren in docstrings.
    Added reverse() sanity tests to test_array.py.
2000-09-16 22:31:29 +00:00
Tim Peters bb307343e4 General cleanup in preparation for a bugfix: removed unused code, useless
declarations, added some comments where I had to think too hard to
understand what was happening, and changed the primary internal get/set
functions to assert they're passed objects of the correct type instead of
doing runtime tests for that (it's an internal error that "should never
happen", so it's good enough to check it only in the debug build).
2000-09-10 05:22:54 +00:00
Guido van Rossum 8586991099 REMOVED all CWI, CNRI and BeOpen copyright markings.

Trent Mick 6c116dd56b Use safer comparisons (only matters when sizeof(int) != sizeof(size_t)). fread
and fwrite return size_t, so it is safer to cast up to the largest type for the

Thomas Wouters f3f33dcf03 Bunch of minor ANSIfications: 'void initfunc()' -> 'void initfunc(void)',
and a couple of functions that were missed in the previous batches. Not
terribly tested, but very carefully scrutinized, three times.

All these were found by the little findkrc.py that I posted to python-dev,
which means there might be more lurking. Cases such as this:

long
func(a, b)
	long a;
	long b; /* flagword */
{

and other cases where the last ; in the argument list isn't followed by a
newline and an opening curly bracket. Regexps to catch all are welcome, of
course ;)

Guido van Rossum db67739d4f Jack Jansen, Mac patch:
Include limits.h if we have it.
2000-07-01 01:09:43 +00:00
Guido van Rossum 9f754e0e2d In b_setitem(), instead of the platform dependent CHAR_MIN and
CHAR_MAX, use hardcoded -128 and 127.  This may seem strange, unless
you realize that we're talking about signed bytes here!  Bytes are
always 8 bits and 2's complement.  CHAR_MIN and CHAR_MAX are
properties of the char data type, which is guaranteed to hold at least
8 bits anyway.

Otherwise you'd get failing tests on platforms where unsigned char is
the default (e.g. AIX).

Thanks, Vladimir Marangozov, for finding this nit!

Guido van Rossum 7d0ae5e14e Trent Mick: use size_t instead of int where appropriate (in
fromfile(), to hold fread() result.)
2000-06-28 21:27:21 +00:00
Fred Drake 541dc3b7b2 Trent Mick <trentm@activestate.com>:
The cause: Relatively recent (last month) patches to getargs.c added
overflow checking to the PyArg_Parse*() integral formatters thereby
restricting 'b' to unsigned char value and 'h','i', and 'l' to signed
integral values (i.e. if the incoming value is outside of the
specified bounds you get an OverflowError, previous it silently
overflowed).

The problem: This broke the array module (as Fredrik pointed out)
because *its* formatters relied on the loose allowance of signed and
unsigned ranges being able to pass through PyArg_Parse*()'s
formatters.

The fix: This patch fixes the array module to work with the more
strict bounds checking now in PyArg_Parse*().

How: If the type signature of a formatter in the arraymodule exactly
matches one in PyArg_Parse*(), then use that directly. If there is no
equivalent type signature in PyArg_Parse*() (e.g. there is no unsigned
int formatter in PyArg_Parse*()), then use the next one up and do some
extra bounds checking in the array module.

This partially closes SourceForge patch #100506.

For documentation read the comments in mymalloc.h and objimpl.h.

(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode.  I'm also holding back on his
change to main.c, which seems unnecessary to me.)
