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.

Christian Heimes 593daf545b Renamed PyString to PyBytes 2008-05-26 12:51:38 +00:00
Neal Norwitz b1d3d96374 Issue 2332: add new attribute names for instance method objects 2008-03-18 04:46:00 +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
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.
2008-02-06 13:33:44 +00:00
Christian Heimes 6075a82243 Limit free list of method and builtin function objects to 256 entries each. 2008-02-06 12:44:34 +00:00
Jeffrey Yasskin a26cf9b760 Make int() and long() fall back to __trunc__(). See issue 2002. 2008-02-04 01:04:35 +00:00
Guido van Rossum 9ff1a44973 Fix an edge case whereby the __del__() method of a classic class could
create a new weakref to the object.
2008-01-18 20:56:30 +00:00
Kristján Valur Jónsson abe1d48d20 As per Armin Rigo's suggestion, remove special handing from intobject.c to deal with the peculiarities of classobject's implementation of the number protocol. The nb_long method of classobject now falls back to nb_int if there is no __long__ attribute present. 2007-05-07 16:46:54 +00:00
Martin v. Löwis 3a62404264 Correctly forward exception in instance_contains().
Fixes #1591996. Patch contributed by Neal Norwitz.
Will backport.
2006-11-08 06:46:37 +00:00
Georg Brandl 5d59c09834 Patch #1567691: super() and new.instancemethod() now don't accept
keyword arguments any more (previously they accepted them, but didn't
use them).
2006-09-30 08:43:30 +00:00
Neal Norwitz 6cbb726539 Move initialization of interned strings to before allocating the
object so we don't leak op.  (Fixes an earlier patch to this code)

Klockwork #350
2006-08-19 04:22:33 +00:00
Neal Norwitz af33f2d571 Can't return NULL from a void function. If there is a memory error,
about the best we can do is call PyErr_WriteUnraisable and go on.
We won't be able to do the call below either, so verify delstr is valid.
2006-08-14 00:59:03 +00:00
Neal Norwitz b09f4f578f Handle a whole lot of failures from PyString_FromInternedString().
Should fix most of Klocwork 234-272.
2006-08-13 18:10:28 +00:00
Neal Norwitz 1872b1c01f Fix a couple of bugs exposed by the new __index__ code. The 64-bit buildbots
were failing due to inappropriate clipping of numbers larger than 2**31
with new-style classes. (typeobject.c)  In reviewing the code for classic
classes, there were 2 problems.  Any negative value return could be returned.
Always return -1 if there was an error.  Also make the checks similar
with the new-style classes.  I believe this is correct for 32 and 64 bit
boxes, including Windows64.

Add a test of classic classes too.
2006-08-12 18:44:06 +00:00
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.
2006-08-12 17:03:09 +00:00
Martin v. Löwis ab2f8f7bd5 __hash__ may now return long int; the final hash
value is obtained by invoking hash on the long int.
Fixes #1536021.
2006-08-09 07:57:39 +00:00
Brett Cannon ea3912b0da If a classic class defined a __coerce__() method that just returned its two
arguments in reverse, the interpreter would infinitely recourse trying to get a
coercion that worked.  So put in a recursion check after a coercion is made and
the next call to attempt to use the coerced values.

Fixes bug #992017 and closes crashers/coerce.py .

Armin Rigo fd01d7933b (arre, arigo) SF bug #1350060
Give a consistent behavior for comparison and hashing of method objects
(both user- and built-in methods).  Now compares the 'self' recursively.
The hash was already asking for the hash of 'self'.
2006-06-08 10:56:24 +00:00
Georg Brandl 2cfaa34dfa Correct some value converting strangenesses. 2006-05-29 19:39:45 +00:00
Georg Brandl e4e023c4d3 Simplify calling. 2006-05-26 20:22:50 +00:00
Georg Brandl 684fd0c8ec Replace PyObject_CallFunction calls with only object args
with PyObject_CallFunctionObjArgs, which is 30% faster.

Martin v. Löwis 6685128b97 Fix more ssize_t issues. 2006-04-22 11:40:03 +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
2006-04-15 21:47:09 +00:00
Anthony Baxter 377be11ee1 More C++-compliance. Note especially listobject.c - to get C++ to accept the
PyTypeObject structures, I had to make prototypes for the functions, and
move the structure definition ahead of the functions. I'd dearly like a better
way to do this - to change this would make for a massive set of changes to
the codebase.

There's still some warnings - this is purely to get rid of errors first.

Georg Brandl 347b30042b Remove unnecessary casts in type object initializers. 2006-03-30 11:57:00 +00:00
Neal Norwitz badc086543 Stop duplicating code and handle slice indices consistently and correctly
wrt to ssize_t.
2006-03-23 06:03:08 +00:00
Neal Norwitz 2aa9a5dfdd Use macro versions instead of function versions when we already know the type.
This will hopefully get rid of some Coverity warnings, be a hint to
developers, and be marginally faster.

Some asserts were added when the type is currently known, but depends
on values from another function.

Guido van Rossum 38fff8c4e4 Checking in the code for PEP 357.
This was mostly written by Travis Oliphant.
I've inspected it all; Neal Norwitz and MvL have also looked at it
(in an earlier incarnation).

Jeremy Hylton af68c874a6 Add const to several API functions that take char *.
In C++, it's an error to pass a string literal to a char* function
without a const_cast().  Rather than require every C++ extension
module to put a cast around string literals, fix the API to state the
const-ness.

I focused on parts of the API where people usually pass literals:
PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type
slots, etc.  Predictably, there were a large set of functions that
needed to be fixed as a result of these changes.  The most pervasive
change was to make the keyword args list passed to
PyArg_ParseTupleAndKewords() to be a const char *kwlist[].

One cast was required as a result of the changes:  A type object
mallocs the memory for its tp_doc slot and later frees it.
PyTypeObject says that tp_doc is const char *; but if the type was
created by type_new(), we know it is safe to cast to char *.

Guido van Rossum 630db60a55 - On 64-bit platforms, when __len__() returns a value that cannot be
represented as a C int, raise OverflowError.

(Forward port from 2.4.2; the patch to classobject.c was already in
but needed a correction in the error message text.)
2005-09-20 18:49:54 +00:00
Guido van Rossum ba3e6ec0c9 A minor fix for 64-bit platforms: when __len__() returns Python int
containing a value that doesn't fit in a C int, raise OverflowError
rather than truncating silently (and having 50% chance of hitting the
"it should be >= 0" error).

Michael W. Hudson e2749cb264 Fix for rather inaccurately titled bug
[ 1165306 ] Property access with decorator makes interpreter crash

Don't allow the creation of unbound methods with NULL im_class, because
attempting to call such crashes.

Backport candidate.

Tim Peters f4aca755bc A static swapped_op[] array was defined in 3 different C files, & I think
I need to define it again.  Bite the bullet and define it once as an
extern, _Py_SwappedOp[].
2004-09-23 02:39:37 +00:00
Michael W. Hudson 3f3b66823f Repair the same thinko in two places about handling of _Py_RefTotal in
the case of __del__ resurrecting an object.
This makes the apparent reference leaks in test_descr go away (which I
expected) and also kills off those in test_gc (which is more surprising
but less so once you actually think about it a bit).
2004-08-03 10:21:03 +00:00
Guido van Rossum baf0f8f24d - When method objects have an attribute that can be satisfied either
by the function object or by the method object, the function
  object's attribute usually wins.  Christian Tismer pointed out that
  that this is really a mistake, because this only happens for special
  methods (like __reduce__) where the method object's version is
  really more appropriate than the function's attribute.  So from now
  on, all method attributes will have precedence over function
  attributes with the same name.

Armin Rigo 2b3eb4062c Deleting cyclic object comparison.
SF patch 825639

Raymond Hettinger 8ae4689657 Simplify and speedup uses of Py_BuildValue():
* Py_BuildValue("(OOO)",a,b,c)  -->  PyTuple_Pack(3,a,b,c)
* Py_BuildValue("()",a)         -->  PyTuple_New(0)
* Py_BuildValue("O", a)         -->  Py_INCREF(a)

Raymond Hettinger a9e14b7015 Fix leak in classobject.c. The leak surfaced on the error exit when
hashing a class that does not define __hash__ but does define a
comparison.
2003-09-16 07:11:46 +00:00
Guido van Rossum 2fb9fdc96a Make it possible to call instancemethod() with 2 arguments. 2003-04-09 19:35:08 +00:00
Tim Peters df875b99fc New private API function _PyInstance_Lookup. gc will use this to figure
out whether __del__ exists, without executing any Python-level code.
2003-04-07 17:51:59 +00:00
Guido van Rossum 6bae46d8c1 Refactor instancemethod_descr_get() to (a) be more clear, (b) be safe
in the light of weird args, and (c) not to expect None (which is now
changed to NULL by slot_tp_descr_get()).
2003-02-11 18:43:00 +00:00
Raymond Hettinger ea3fdf44a2 SF patch #659536: Use PyArg_UnpackTuple where possible.
Obtain cleaner coding and a system wide
performance boost by using the fast, pre-parsed
PyArg_Unpack function instead of PyArg_ParseTuple
function which is driven by a format string.
2002-12-29 16:33:45 +00:00
Walter Dörwald 7e5c6a02eb Change issubclass() so that recursive tuples (directly or indirectly
containing class objects) are allowed as the second argument.
This makes issubclass() more similar to isinstance() where recursive
tuples are allowed too.
2002-12-12 19:14:08 +00:00
Walter Dörwald d9a6ad3beb Enhance issubclass() and PyObject_IsSubclass() so that a tuple is
supported as the second argument. This has the same meaning as
for isinstance(), i.e. issubclass(X, (A, B)) is equivalent
to issubclass(X, A) or issubclass(X, B). Compared to isinstance(),
this patch does not search the tuple recursively for classes, i.e.
any entry in the tuple that is not a class, will result in a
TypeError.

This closes SF patch #649608.
2002-12-12 16:41:44 +00:00
Guido van Rossum f740bdf337 Since properties are supported here, is possible that
instance_getattr2() raises an exception.  Fix all code that made this
assumption.

Backport candidate.
