Guido van Rossum 1859f5b4d2 Backport r60246.
Fix issue #1303614, test67.py.
2008-01-24 17:59:56 +00:00
Marc-André Lemburg 040f76b79c Slightly revised version of patch #1538956:
Replace UnicodeDecodeErrors raised during == and !=
compares of Unicode and other objects with a new
UnicodeWarning.

All other comparisons continue to raise exceptions.
Exceptions other than UnicodeDecodeErrors are also left
untouched.

Martin v. Löwis 45294a9562 Remove types from type_list if they have no objects
and unlist_types_without_objects is set.
Give dump_counts a FILE* argument.

Anthony Baxter ac6bd46d5c spread the extern "C" { } magic pixie dust around. Python itself builds now
using a C++ compiler. Still lots and lots of errors in the modules built by
setup.py, and a bunch of warnings from g++ in the core.

Armin Rigo e170937af6 Ignore the references to the dummy objects used as deleted keys
in dicts and sets when computing the total number of references.

Tim Peters cbd6f1896d _Py_PrintReferenceAddresses,_Py_PrintReferences:
interpolate PY_FORMAT_SIZE_T for refcount display
instead of casting refcounts to long.

I understand that gcc on some boxes delivers
nuisance warnings about this, but if any new ones
appear because of this they'll get fixed by magic
when the others get fixed.

Georg Brandl 347b30042b Remove unnecessary casts in type object initializers. 2006-03-30 11:57:00 +00:00
Anthony Baxter 262c00a21e Fixed bug #1459029 - unicode reprs were double-escaped.
Backed out an old patch from 2000.

Tim Peters 8af92d1f6c Heh -- used the right format for a refcount, but forgot
to stop truncating it.

Tim Peters 4d073bb9a1 _Py_NegativeRefcount(): print the full value of ob_refcnt. 2006-03-23 05:38:33 +00:00
Neal Norwitz 7580146b5c Fix and test (manually w/xx module) passing NULLs to PyObject_Str() and
PyObject_Unicode().  This problem was originally reported from Coverity
and addresses mail on python-dev "checkin r43015".

This inlines the conversion of the string to unicode and cleans
up/simplifies some code at the end of the PyObject_Unicode().

We really need a complete C API test module for all public APIs
and passing good and bad parameter values.

Will backport.

Georg Brandl 3daf75878d Fix bug found by Coverity: don't allow NULL argument to PyUnicode_CheckExact 2006-03-13 22:22:11 +00:00
Martin v. Löwis 725507b52e Change int to Py_ssize_t in several places.
Add (int) casts to silence compiler warnings.
Raise Python exceptions for overflows.
2006-03-07 12:08:51 +00:00
Neal Norwitz 84632ee319 Oops, forgot to include this in the last checkin.
Actually define Py_RefTotal as a Py_ssize_t.
2006-03-04 20:00:59 +00:00
Thomas Wouters 8b87a0b5fc Use %ld and casts to long for refcount printing, in absense of a universally
available %zd format character. Mark with an XXX comment so we can fix this,
later.

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 *.

Neil Schemenauer cf52c07843 Change the %s format specifier for str objects so that it returns a
unicode instance if the argument is not an instance of basestring and
calling __str__ on the argument returns a unicode instance.
2005-08-12 17:34:58 +00:00
Brett Cannon c3647ac93e Make subclasses of int, long, complex, float, and unicode perform type
conversion using the proper magic slot (e.g., __int__()).  Also move conversion
code out of PyNumber_*() functions in the C API into the nb_* function.

Applied patch #1109424.  Thanks Walter Doewald.

Armin Rigo a174813113 Dima Dorfman's patch for coercion/comparison of C types (patch #995939), with
a minor change after the coercion, to accept two objects not necessarily of
the same type but with the same tp_compare.

Brett Cannon a5ca2e7220 Remove 'extern' declaration for _Py_SwappedOp. 2004-09-25 01:37:24 +00:00
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[].

Fred Drake 0a4dd390bf Make weak references subclassable:
- weakref.ref and weakref.ReferenceType will become aliases for each
  other

- weakref.ref will be a modern, new-style class with proper __new__
  and __init__ methods

- weakref.WeakValueDictionary will have a lighter memory footprint,
  using a new weakref.ref subclass to associate the key with the
  value, allowing us to have only a single object of overhead for each
  dictionary entry (currently, there are 3 objects of overhead per
  entry: a weakref to the value, a weakref to the dictionary, and a
  function object used as a weakref callback; the weakref to the
  dictionary could be avoided without this change)

- a new macro, PyWeakref_CheckRefExact(), will be added

- PyWeakref_CheckRef() will check for subclasses of weakref.ref

This closes SF patch #983019.

Raymond Hettinger 214b1c3aae SF Bug #215126: Over restricted type checking on eval() function
The builtin eval() function now accepts any mapping for the locals argument.
Time sensitive steps guarded by PyDict_CheckExact() to keep from slowing
down the normal case.  My timings so no measurable impact.

Thomas Heller 1328b52c6f Two new public API functions, Py_IncRef and Py_DecRef. Useful for

Michael W. Hudson b2c7de4667 Fix for
[ 784825 ] fix obscure crash in descriptor handling

Should be applied to release23-maint and in all likelyhood
release22-maint, too.

Certainly doesn't apply to release21-maint.

Tim Peters 21d7d4d5ca _Py_PrintReferenceAddresses(): also print the type name. In real use
I'm finding some pretty baffling output, like reprs consisting entirely
of three left parens.  At least this will let us know what type the object
is (it's not str -- there's no quote character in the repr).

New tool combinerefs.py, to combine the two output blocks produced via
PYTHONDUMPREFS.
2003-04-18 00:45:59 +00:00
Tim Peters 269b2a6797 _Py_PrintReferences(): Changed to print object address at start of each
new line.

New pvt API function _Py_PrintReferenceAddresses():  Prints only the
addresses and refcnts of the live objects.  This is always safe to call,
because it has no dependence on Python's C API.

Py_Finalize():  If envar PYTHONDUMPREFS is set, call (the new)
_Py_PrintReferenceAddresses() right before dumping final pymalloc stats.
We can't print the reprs of the objects here because too much of the
interpreter has been shut down.  You need to correlate the addresses
displayed here with the object reprs printed by the earlier
PYTHONDUMPREFS call to _Py_PrintReferences().
2003-04-17 19:52:29 +00:00
Guido van Rossum 0fc8f00252 - pythunrun.c, Py_Finalize(): move the call to _Py_PrintReferences()
even farther down, to just before the call to
  _PyObject_DebugMallocStats().  This required the following changes:

- pystate.c, PyThreadState_GetDict(): changed not to raise an
  exception or issue a fatal error when no current thread state is
  available, but simply return NULL without raising an exception
  (ever).

- object.c, Py_ReprEnter(): when PyThreadState_GetDict() returns NULL,
  don't raise an exception but return 0.  This means that when
  printing a container that's recursive, printing will go on and on
  and on.  But that shouldn't happen in the case we care about (see
  first bullet).

- Updated Misc/NEWS and Doc/api/init.tex to reflect changes to
  PyThreadState_GetDict() definition.

Tim Peters 51f8d38185 Typo in comment. 2003-03-23 18:06:08 +00:00
Tim Peters 7571a0fbcf Improved new Py_TRACE_REFS gimmicks.
Arranged that all the objects exposed by __builtin__ appear in the list
of all objects.  I basically peed away two days tracking down a mystery
leak in sys.gettotalrefcount() in a ZODB app (== tons of code), because
the object leaking the references didn't appear in the sys.getobjects(0)
list.  The object happened to be False.  Now False is in the list, along
with other popular & previously missing leak candidates (like None).
Alas, we still don't have a choke point covering *all* Python objects,
so the list of all objects may still be incomplete.
2003-03-23 17:52:28 +00:00
Tim Peters 36eb4dfb81 Refactored some of the Py_TRACE_REFS code. New private API function
_Py_AddToAllObjects() that simply inserts an object at the front of
the doubly-linked list of all objects.  Changed PyType_Ready() (the
 closest thing we've got to a choke point for type objects) to call
that.
2003-03-23 03:33:13 +00:00
Tim Peters 3e40c7ff5b Oops! Used a wrong preprocessor symbol. 2003-03-23 03:04:32 +00:00
Tim Peters 78be7993b6 When Py_TRACE_REFS is defined, a list of all live objects is maintained in
a doubly-linked list, exposed by sys.getobjects().  Unfortunately, it's not
really all live objects, and it seems my fate to bump into programs where
sys.gettotalrefcount() keeps going up but where the reference leaks aren't
accounted for by anything in the list of all objects.

This patch helps a little:  if COUNT_ALLOCS is also defined, from now on
type objects will also appear in this list, provided at least one object
of a type has been allocated.

Raymond Hettinger 1da1dbf458 Renamed PyObject_GenericGetIter to PyObject_SelfIter
to more accurately describe what the function does.

Suggested by Thomas Wouters.
2003-03-17 19:46:11 +00:00
Raymond Hettinger 0153826964 Created PyObject_GenericGetIter().
Factors out the common case of returning self.
2003-03-17 08:24:35 +00:00
Guido van Rossum 90195e2616 PyObject_Generic{Get,Set}Attr:
Don't access tp_descr_{get,set} of a descriptor without checking the
flag bits of the descriptor's type.  While we know that the main type
(the type of the object whose attribute is being accessed) has all the
right flag bits (or else PyObject_Generic{Get,Set}Attr wouldn't be
called), we don't know that for its class attributes!

Will backport to 2.2.
