Amaury Forgeot d'Arc 595f7a5bf9 #2016 Fix a crash in function call when the **kwargs dictionary is mutated
during the function call setup.

This even gives a slight speedup, probably because tuple allocation
is faster than PyMem_NEW.

Raymond Hettinger 578a228ee2 Issue 5982: Classmethod and staticmethod expose wrapped function with __func__. 2009-05-29 04:58:52 +00:00
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.

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.
Have fun! :)

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

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 *.

Jeremy Hylton 3e0055f8c6 Merge ast-branch to head
This change implements a new bytecode compiler, based on a
transformation of the parse tree to an abstract syntax defined in
Parser/Python.asdl.

The compiler implementation is not complete, but it is in stable
enough shape to run the entire test suite excepting two disabled
tests.

[ 1124295 ] Function's __name__ no longer accessible in restricted mode

which I introduced with a bit of mindless copy-paste when making
__name__ writable.  You can't assign to __name__ in restricted mode,
which I'm going to pretend was intentional :)

Armin Rigo 89a39461bf Wrote down the invariants of some common objects whose structure is
exposed in header files.  Fixed a few comments in these headers.

As we might have expected, writing down invariants systematically exposed a
(minor) bug.  In this case, function objects have a writeable func_code
attribute, which could be set to code objects with the wrong number of
free variables.  Calling the resulting function segfaulted the interpreter.
Added a corresponding test.

Jeremy Hylton 400d8ee6fa Make staticmethods and classmethods participate in GC.
If a class was defined inside a function, used a static or class
method, and used super() inside the method body, it would be caught in
an uncollectable cycle.  (Simplified version: The static/class method
object would point to a function object with a closure that referred
to the class.)

Bugfix candidate.

Guido van Rossum 6b29c0147b Make __module__ writable except in restricted mode (like for classic classes). 2003-02-18 17:18:35 +00:00
Jeremy Hylton ff71c98449 Make __module__ settable on functions and methods. 2003-02-18 17:02:15 +00:00
Jeremy Hylton 4f0dcc9a9a Provide __module__ attributes for functions defined in C and Python.
__module__ is the string name of the module the function was defined
in, just like __module__ of classes.  In some cases, particularly for
C functions, the __module__ may be None.

Change PyCFunction_New() from a function to a macro, but keep an
unused copy of the function around so that we don't change the binary
API.

Change pickle's save_global() to use whichmodule() if __module__ is
None, but add the __module__ logic to whichmodule() since it might be
used outside of pickle.

Raymond Hettinger ea3fdf44a2 SF patch #659536: Use PyArg_UnpackTuple where possible.

function which is driven by a format string.

Guido van Rossum bea18ccde6 SF patch 568629 by Oren Tirosh: types made callable.
These built-in functions are replaced by their (now callable) type:

    slice()
    buffer()

and these types can also be called (but have no built-in named
function named after them)

    classobj (type name used to be "class")
    code
    function
    instance
    instancemethod (type name used to be "instance method")

The module "new" has been replaced with a small backward compatibility
placeholder in Python.

A large portion of the patch simply removes the new module from
various platform-specific build recipes.  The following binary Mac
project files still have references to it:

    Mac/Build/PythonCore.mcp
    Mac/Build/PythonStandSmall.mcp
    Mac/Build/PythonStandalone.mcp

[I've tweaked the code layout and the doc strings here and there, and
added a comment to types.py about StringTypes vs. basestring.  --Guido]

Guido van Rossum 7e30548285 Fix for SF bug 528132 (Armin Rigo): classmethod().__get__() segfault
The proper fix is not quite what was submitted; it's really better to
take the class of the object passed rather than calling PyMethod_New
with NULL pointer args, because that can then cause other core dumps
later.

I also added a testcase for the fix to classmethods() in test_descr.py.

I've already applied this to the 2.2 branch.

Fred Drake c916f5a390 Be smarter about clearing the weakref lists for instances, instance methods,
and functions: we only need to call PyObject_ClearWeakRefs() if the weakref
list is non-NULL.  Since these objects are common but weakrefs are still
unusual, saving the call at deallocation time makes a lot of sense.
2001-10-26 17:56:51 +00:00
Guido van Rossum 9475a2310d Enable GC for new-style instances. This touches lots of files, since
many types were subclassable but had a xxx_dealloc function that
called PyObject_DEL(self) directly instead of deferring to
self->ob_type->tp_free(self).  It is permissible to set tp_free in the
type object directly to _PyObject_Del, for non-GC types, or to
_PyObject_GC_Del, for GC types.  Still, PyObject_DEL was a tad faster,
so I'm fearing that our pystone rating is going down again.  I'm not
sure if doing something like

void xxx_dealloc(PyObject *self)
{
	if (PyXxxCheckExact(self))
		PyObject_DEL(self);
	else
		self->ob_type->tp_free(self);
}

is any faster than always calling the else branch, so I haven't
attempted that -- however those types whose own dealloc is fancier
(int, float, unicode) do use this pattern.

Guido van Rossum 32d34c809f Add optional docstrings to getset descriptors. Fortunately, there's
no backwards compatibility to worry about, so I just pushed the
'closure' struct member to the back -- it's never used in the current
code base (I may eliminate it, but that's more work because the getter
and setter signatures would have to change.)

As examples, I added actual docstrings to the getset attributes of a
few types: file.closed, xxsubtype.spamdict.state.
2001-09-20 21:45:26 +00:00
Guido van Rossum 6f7993765a Add optional docstrings to member descriptors. For backwards
compatibility, this required all places where an array of "struct
memberlist" structures was declared that is referenced from a type's
tp_members slot to change the type of the structure to PyMemberDef;
"struct memberlist" is now only used by old code that still calls
PyMember_Get/Set.  The code in PyObject_GenericGetAttr/SetAttr now
calls the new APIs PyMember_GetOne/SetOne, which take a PyMemberDef
argument.

As examples, I added actual docstrings to the attributes of a few
types: file, complex, instance method, super, and xxsubtype.spamlist.

Also converted the symtable to new style getattr.
