Neil Schemenauer e3550a65eb - fix a GC bug caused by malloc() failing 2000-10-04 16:20:41 +00:00
Tim Peters 6b184918f6 Fix for SF bug 110688: Instance deallocation neglected to account for
that Py_INCREF boosts global _Py_RefTotal when Py_REF_DEBUG is defined
but Py_TRACE_REFS isn't.

There are, IMO, way too many preprocessor gimmicks in use for refcount
debugging (at least 3 distinct true/false symbols, but not all 8 combos
are supported by the code, etc etc), and no coherent documentation of
this stuff -- 'twas too painful to track this one down.

Neil Schemenauer ce20967c2c Don't remove instance objects from the GC container set until we are
they are dead.  Fixes bug #113812.

Guido van Rossum 8586991099 REMOVED all CWI, CNRI and BeOpen copyright markings.
This should match the situation in the 1.6b1 tree.

Jeremy Hylton b709df3810 refactor __del__ exception handler into PyErr_WriteUnraisable
add sanity check to gc: if an exception occurs during GC, call
PyErr_WriteUnraisable and then call Py_FatalEror.

Thomas Wouters 1de2a79a48 Call PyErr_Clear() to clear the AttributeError raised by GetAttr. 2000-08-25 10:47:46 +00:00
Thomas Wouters e289e0bd0c Support for the in-place operations introduced by augmented assignment. Only
the list object supports this currently, but other candidates are
gladly accepted (like arraymodule and such.)

Barry Warsaw dc55d715bb PyInstance_DoBinOp(): When comparing the pointers, they must be cast
to integer types (i.e. Py_uintptr_t, our spelling of C9X's uintptr_t).
ANSI specifies that pointer compares other than == and != to
non-related structures are undefined.  This quiets an Insure
portability warning.

Thomas Wouters 1d75a79c00 Apply SF patch #101029: call __getitem__ with a proper slice object if there
is no __getslice__ available. Also does the same for C extension types.
Includes rudimentary documentation (it could use a cross reference to the
section on slice objects, I couldn't figure out how to do that) and a test
suite for all Python __hooks__ I could think of, including the new
behaviour.

Thomas Wouters c307352027 ANSIfy functions that were hiding inside a macro. 2000-07-23 22:09:59 +00:00
Thomas Wouters 7e47402264 Spelling fixes supplied by Rob W. W. Hooft. All these are fixes in either
comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").

There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)

Fred Drake a44d353e2b Trent Mick <trentm@activestate.com>:
The common technique for printing out a pointer has been to cast to a long
and use the "%lx" printf modifier. This is incorrect on Win64 where casting
to a long truncates the pointer. The "%p" formatter should be used instead.

The problem as stated by Tim:
> Unfortunately, the C committee refused to define what %p conversion "looks
> like" -- they explicitly allowed it to be implementation-defined. Older
> versions of Microsoft C even stuck a colon in the middle of the address (in
> the days of segment+offset addressing)!

The result is that the hex value of a pointer will maybe/maybe not have a 0x
prepended to it.


Notes on the patch:

There are two main classes of changes:
- in the various repr() functions that print out pointers
- debugging printf's in the various thread_*.h files (these are why the
patch is large)


Closes SourceForge patch #100505.

Jeremy Hylton c5007aa5c3 final patches from Neil Schemenauer for garbage collection 2000-06-30 05:02:53 +00:00
Fred Drake 13634cf7a4 This patch addresses two main issues: (1) There exist some non-fatal
errors in some of the hash algorithms. For exmaple, in float_hash and
complex_hash a certain part of the value is not included in the hash
calculation. See Tim's, Guido's, and my discussion of this on
python-dev in May under the title "fix float_hash and complex_hash for
64-bit *nix"

(2) The hash algorithms that use pointers (e.g. func_hash, code_hash)
are universally not correct on Win64 (they assume that sizeof(long) ==
sizeof(void*))

As well, this patch significantly cleans up the hash code. It adds the
two function _Py_HashDouble and _PyHash_VoidPtr that the various
hashing routine are changed to use.

These help maintain the hash function invariant: (a==b) =>
(hash(a)==hash(b))) I have added Lib/test/test_hash.py and
Lib/test/output/test_hash to test this for some cases.

Guido van Rossum d7823f2645 Vladimir Marangozov:
Avoid calling the dealloc function, previously triggered with
DECREF(inst).  This caused a segfault in PyDict_GetItem, called with a
NULL dict, whenever inst->in_dict fails under low-memory conditions.

Guido van Rossum ad89bbcd88 Trent Mick: change a few casts for Win64 compatibility. 2000-06-28 21:57:18 +00:00
Jeremy Hylton d08b4c4524 part 2 of Neil Schemenauer's GC patches:
This patch modifies the type structures of objects that
participate in GC.  The object's tp_basicsize is increased when
GC is enabled.  GC information is prefixed to the object to
maintain binary compatibility.  GC objects also define the
tp_flag Py_TPFLAGS_GC.

This patch adds the type methods traverse and clear necessary for GC
implementation.

Guido van Rossum b18618dab7 Vladimir Marangozov's long-awaited malloc restructuring.
For more comments, read the patches@python.org archives.
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.)
2000-05-03 23:44:39 +00:00
Jeremy Hylton 9e392e2412 potentially useless optimization
The previous checkin (2.84) added a PyErr_Format call that made the
cost of raising an AttributeError much more expensive.  In general
this doesn't matter, except that checks for __init__ and
__del__ methods, where exceptions are caught and cleared in C, also
got much more expensive.

The fix is to split instance_getattr1 into two calls:

instance_getattr2 checks the instance and the class for the attribute
and returns it or returns NULL on error.  It does not raise an
exception.

instance_getattr1 does rexec checks, then calls instance_getattr2.  It
raises an exception if instance_getattr2 returns NULL.

PyInstance_New and instance_dealloc now call instance_getattr2
directly.
2000-04-26 20:39:20 +00:00
Guido van Rossum 5f8b12f27e Mark Hammond:
In line with a similar checkin to object.c a while ago, this patch
gives a more descriptive error message for an attribute error on a
class instance.  The message now looks like:

AttributeError: 'Descriptor' instance has no attribute 'GetReturnType'
2000-04-10 13:03:19 +00:00
Guido van Rossum ee28c3a5ea Patch by Mozhe Zadka, for __contains__ (overloading 'in'). This adds
an instance method instance_contains as sq_contains.  It looks for
__contains__ and if not found falls back to previous behaviour.
Done.
2000-02-28 15:03:15 +00:00
Guido van Rossum bffd683f73 The rest of the changes by Trent Mick and Dale Nagata for warning-free
compilation on NT Alpha.  Mostly added casts etc.
2000-01-20 22:32:56 +00:00
Guido van Rossum 42636dc64d Fix for PR#98 (Adrian Eyre) -- in instancemethod_repr, the funcname
object is DECREFed too early.
1999-10-11 14:03:12 +00:00
Guido van Rossum 152d8173a3 Fix a memory leak -- the cached values of __getattr__ etc. were never
freed.
1998-08-04 14:59:16 +00:00
Guido van Rossum d4ba73c75b Move the definition of PyMethodObject to classobject.h, so it can define
macros for more efficient access to the fields.
1998-07-10 15:46:33 +00:00
Guido van Rossum 7859f87fdb Marc-Andre Lemburg's patch to support instance methods with other
callable objects than regular Pythonm functions as their im_func.
1998-07-08 14:58:16 +00:00
Guido van Rossum 7ba30431ec Recompute the special getattr/setattr/delattr cache slots after
changing __dict__ *or* __bases__.
1998-07-08 13:34:48 +00:00
Guido van Rossum e0fdf6f1a8 Keep Microsoft's compiler happy. 1998-06-12 15:03:58 +00:00
Guido van Rossum a63eff6e6a Allow assignments to special class attributes -- with typechecks, and
not in restricted mode.

__dict__ can be set to any dictionary; the cl_getattr, cl_setattr and
cl_delattr slots are refreshed.

__name__ can be set to any string.

__bases__ can be set to to a tuple of classes, provided they are not
subclasses of the class whose attribute is being assigned.

__getattr__, __setattr__ and __delattr__ can be set to anything, or
deleted; the appropriate slot (cl_getattr, cl_setattr, cl_delattr) is
refreshed.

(Note: __name__ really doesn't need to be a special attribute, but
that would be more work.)
1998-05-29 21:37:21 +00:00
Guido van Rossum 617c1b0116 Uses PyErr_ExceptionMatches() instead of comparing PyErr_Occurred(). 1998-05-28 19:50:02 +00:00
Guido van Rossum 4180cf1649 Remove a redundant statement from halfbinop(). 1998-05-13 22:02:16 +00:00
Guido van Rossum b7f1afe4a8 Change the default repr() and str() of class instance objects to look
like <modulename.classname instance at ...> (to match the repr() of
class objects.
1997-12-03 00:06:02 +00:00
Guido van Rossum 3931df9250 Undo another glitch of the automatic not-so-Grand Renaming; some local
variables called 'coerce' were accidentally renamed to
'PyNumber_Coerce'.  Rename them back to coercefunc.
1997-11-18 19:23:07 +00:00
Guido van Rossum 4a2a621907 Write a str() function for class objects that returns
"modulename.classname" instead of returning the same as repr().
1997-10-20 23:26:11 +00:00
Guido van Rossum 04d73c495e Check that all base classes are indeed class objects, rather than
expecting the caller to do so.
1997-10-07 14:54:11 +00:00
Guido van Rossum 7cc56eb524 When creating a class, set its __module__ attribute to the module
whose name is in the current globals' __name__ variable.  If __name__
is not set, ignore this.
1997-09-12 20:04:46 +00:00
Guido van Rossum b2173c3146 Allow assignments to instance.__dict__ and instance.__class__. The
former lets you give an instance a set of new instance vars.  The
latter lets you give it a new class.  Both are typechecked and
disallowed in restricted mode.

For classes, the check for read-only special attributes is tightened
so that only assignments to __dict__, __bases__, __name__,
__getattr__, __setattr__, and __delattr__ (these could be made to work
as well, but I don't know if that's useful -- let's see first whether
mucking with instances will help).
1997-08-25 21:23:56 +00:00
Guido van Rossum a0d349f46a Added separate free list for instance method objects, for a few
percent speed up.  Also add PyMethod_Fini() to discard it.
1997-08-05 02:06:53 +00:00
Guido van Rossum c8b6df9004 PyObject_Compare can raise an exception now. 1997-05-23 00:06:51 +00:00

Guido van Rossum 2878a69922 Optimizations by Sjoerd:
- define tp_getattro, tp_setattro
- use precreated string objects for most common exceptions and method names
1996-08-09 20:53:24 +00:00
Guido van Rossum 3cb486879a Only __dict__ and __class__ are read-only instance attributes 1996-07-21 02:29:46 +00:00
Guido van Rossum 441e4ab802 new debugger symbol names 1996-05-23 22:46:51 +00:00
Guido van Rossum 6dabc98400 Added __name__ attribute to class instance method objects.
Removed im_doc attribute; __name__ and __doc__ are now handled by
special casing in instancemethodgetattr().  This saves a few bytes and
INCREF/DECREF calls per i.m. object allocation/deallocation.
1996-05-14 21:54:20 +00:00
Sjoerd Mullender 6f011d7ad5 Get ordering right for TRACE_REFS/COUNT_ALLOCS combination (otherwise

1995-09-18 10:49:04 +00:00
Sjoerd Mullender 740f357363 Fixed calling of __del__ method with TRACE_REFS defined. 1995-08-28 09:00:43 +00:00

Guido van Rossum e7d444f785 * Objects/classobject.c: added 5th (function) parameter to
instancebinop, to support things like Rational * float; added
	documentation strings to classes and methods
1995-01-07 12:35:18 +00:00
Guido van Rossum 6610ad9d6b Added 1995 to copyright message.
floatobject.c: fix hash().
methodobject.c: support METH_FREENAME flag bit.
1995-01-04 19:07:38 +00:00
Guido van Rossum d7047b395e Lots of minor changes. Note for mappingobject.c: the hash table pointer
can now be NULL.
1995-01-02 19:07:15 +00:00
Guido van Rossum bb3c5f7406 fix comparison of instances without _-cmp__ 1994-11-10 22:31:02 +00:00
Sjoerd Mullender b9a6d12498 Comparison of two class instances without __cmp__ or __rcmp__ methods
was broken.
1994-10-19 15:11:52 +00:00
Guido van Rossum 03093a248d * Include/classobject.h, Objects/classobject.c, Python/ceval.c:
entirely redone operator overloading.  The rules for class
	instances are now much more relaxed than for other built-in types
	(whose coerce must still return two objects of the same type)

	* Objects/floatobject.c: add overflow check when converting float
	to int and implement truncation towards zero using ceil/float

	* Objects/longobject.c: change ValueError to OverflowError when
	converting to int

	* Objects/rangeobject.c: modernized

	* Objects/stringobject.c: use HAVE_LIMITS instead of __STDC__

	* Objects/xxobject.c: changed to use new style (not finished?)
1994-09-28 15:51:32 +00:00
Guido van Rossum 52ca98a390 Yet another version (by me) of __getattr__ etc. 1994-09-05 07:32:29 +00:00
Guido van Rossum e773754ae5 Mods (really diffs to 2.29) by Michael Scharf for alternative __getattr__ etc. 1994-09-05 07:31:41 +00:00
Guido van Rossum 91ab4a8353 If an attribute is deleted, __setattr__ is called with 2 instead of 3
arguments (adding __delattr__ was deemed too much overhead)
1994-08-16 22:13:47 +00:00
Guido van Rossum e149fa2a1e * Objects/classobject.c, Include/classobject.h: added __getattr__
and __setattr__ support to override getattr(x, name) and
	setattr(x, name, value) for class instances.  This uses a special
	hack whereby the class is supposed to be static: the __getattr__
	and __setattr__ methods are looked up only once and saved in the
	instance structure for speed
1994-08-12 12:49:46 +00:00
Guido van Rossum b6775db241 Merge alpha100 branch back to main trunk 1994-08-01 11:34:53 +00:00
Guido van Rossum b376a4ad18 * timemodule.c: Add hack for Solaris 2.
* posixmodule.c: don't prototype getcwd() -- it's not portable...
* mappingobject.c: double-check validity of last_name_char in
  dict{lookup,insert,remove}.
* arraymodule.c: need memmove only for non-STDC Suns.
* Makefile: comment out HTML_LIBS and XT_USE by default
* pythonmain.c: don't prototype getopt() -- it's not standardized
* socketmodule.c: cast flags arg to {get,set}sockopt() and addrbuf arg to
  recvfrom() to (ANY*).
* pythonrun.c (initsigs): fix prototype, make it static
* intobject.c (LONG_BIT): only #define it if not already defined
* classobject.[ch]: remove all references to unused instance_convert()
* mappingobject.c (getmappingsize): Don't return NULL in int function.
1993-11-23 17:53:17 +00:00
Sjoerd Mullender 3bb8a05947 Several optimizations and speed improvements.
cstubs: Use Matrix type instead of float[4][4].
1993-10-22 12:04:32 +00:00
Guido van Rossum 21d335ed9e Makefile, import.c: Lance's alternative module search (allow .pyc file
without .py file); Bill's dynamic loading for SunOS using shared
libraries.

pwdmodule.c (mkgrent): remove DECREF of uninitialized variable.

classobject.c (instance_getattr): Fix case when class lookup returns
unbound method instead of function.
1993-10-15 13:01:11 +00:00
Guido van Rossum eb6b33a837 * classobject.c: in instance_getattr, don't make a method out of a
function found as instance data.
* socketmodule.c: added 'flags' argument sendto/recvfrom, rewrite
  argument parsing in send/recv.
* More changes related to access (terminology change: owner instead of
  class; allow any object as owner; local/global variables are owned
  by their dictionary, only class/instance data is owned by the class;
  "from...import *" now only imports objects with public access; etc.)
1993-05-25 09:38:27 +00:00
Guido van Rossum b3f7258f14 * Lots of small changes related to access.
* Added "access *: ...", made access work for class methods.
* Introduced subclass check: make sure that when calling
  ClassName.methodname(instance, ...), the instance is an instance of
  ClassName or of a subclass thereof (this might break some old code!)
1993-05-21 19:56:10 +00:00
Guido van Rossum 81daa32c15 Access checks now work, at least for instance data (not for methods
yet).  The class is now passed to eval_code and stored in the current
frame.  It is also stored in instance method objects.  An "unbound"
instance method is now returned when a function is retrieved through
"classname.funcname", which when called passes the class to eval_code.
1993-05-20 14:24:46 +00:00
Guido van Rossum 25831652fd Several changes in one:
(1) dictionaries/mappings now have attributes values() and items() as
well as keys(); at the C level, use the new function mappinggetnext()
to iterate over a dictionary.

(2) "class C(): ..." is now illegal; you must write "class C: ...".

(3) Class objects now know their own name (finally!); and minor
improvements to the way how classes, functions and methods are
represented as strings.

(4) Added an "access" statement and semantics.  (This is still
experimental -- as long as you don't use the keyword 'access' nothing
should be changed.)
1993-05-19 14:50:45 +00:00
Guido van Rossum 8a0c3456c2 Fix bug in class instance hash (forgot to clear error condition). 1993-04-08 12:56:19 +00:00
Guido van Rossum 9bfef44d97 * Changed all copyright messages to include 1993.
* Stubs for faster implementation of local variables (not yet finished)
* Added function name to code object.  Print it for code and function
  objects.  THIS MAKES THE .PYC FILE FORMAT INCOMPATIBLE (the version
  number has changed accordingly)
* Print address of self for built-in methods
* New internal functions getattro and setattro (getattr/setattr with
  string object arg)
* Replaced "dictobject" with more powerful "mappingobject"
* New per-type functio tp_hash to implement arbitrary object hashing,
  and hashobject() to interface to it
* Added built-in functions hash(v) and hasattr(v, 'name')
* classobject: made some functions static that accidentally weren't;
  added __hash__ special instance method to implement hash()
* Added proper comparison for built-in methods and functions

Guido van Rossum e537240c25 * Changed many files to use mkvalue() instead of newtupleobject().
* Fixcprt.py: added [-y file] option, do only files younger than file.
* modsupport.[ch]: added vmkvalue().
* intobject.c: use mkvalue().
* stringobject.c: added "formatstring"; renamed string* to string_*;
  ceval.c: call formatstring for string % value.
* longobject.c: close memory leak in divmod.
* parsetok.c: set result node to NULL when returning an error.

Guido van Rossum 9e51f9bec8 bltinmodule.c: added round(x, [n]); coerce() of two class instances
will try to coerce anyway.
classobject.c: instance 'nonzero' should first try __nonzero__
only then __len__.
1993-02-12 16:29:05 +00:00
Guido van Rossum d014ea6b5e * classobject.c: in instance_lenth, test result of call_object
for exception before using it.  Fixed a few other places where the
  outcome of calling sq_length wasn't tested for exceptions
  (bltinmodule.c, ceval.c).
1992-11-26 10:30:26 +00:00
Guido van Rossum 7066dd75c5 * Makefile: added IMGFILE; moved some stuff around.
* flmodule.c: added some missing functions; changed readonly flags of
  some data members based upon FORMS documentation.
* listobject.c: fixed int/long arg lint bug (bites PC compilers).
* several: removed redundant print methods (repr is good enough).
* posixmodule.c: added (still experimental) process group functions.

Guido van Rossum 1899c2e055 Made builtins int(), long(), float(), oct() and hex() more generic. 1992-09-12 11:09:23 +00:00
Guido van Rossum 94472a0374 classobject.c moduleobject.c stdwinmodule.c xxobject.c:
raise AttributeError, not KeyError, when attribute deletion fails.
sunaudiodevmodule.c: check for deletion before calling setmember.

Guido van Rossum 6d946f98bd * macmodule.c: include allobjects.h, not .c
* timemodule.c: the mac has no unistd.h
* classobject.c: fixed several cases of return NULL that should be
  return -1 !!!
1992-08-14 13:49:30 +00:00
Guido van Rossum e6eefc2231 * classobject.[ch], {float,long,int}object.c, bltinmodule.c:
coercion is now completely generic.
* ceval.c: for instances, don't coerce for + and *; * reverses
  arguments if left one is non-instance numeric and right one sequence.

Guido van Rossum 04691fc1c1 Changes so that user-defined classes can implement operations invoked
by special syntax: you can now define your own numbers, sequences and
mappings.
