Neal Norwitz faa54a3929 Code review of the new buffer protocol. Mostly add questions that should
be answered with the comments removed.

There are many places that require checks when doing arithmetic for memory
sizes when allocating memory.  Otherwise, overflow is possible with
a subsequent crash.

Fix SF #1777057 which was a result of not initializing the new BufferError
properly.  Had to update the test for exceptions for BufferError too.

    Backout the original 'fix' to 1721309 which had no effect.
    Different versions of Berkeley DB handle this differently.
    The comments and bug report should have the details.  Memory is allocated
    in 4.4 (and presumably earlier), but not in 4.5.  Thus
    4.5 has the free error, but not earlier versions.

    Mostly update comments, plus make the free conditional.

    This fix was already applied to the 2.5 branch.

  Variation of patch # 1624059 to speed up checking if an object is a subclass
  of some of the common builtin types.

  Use a bit in tp_flags for each common builtin type.  Check the bit
  to determine if any instance is a subclass of these common types.
  The check avoids a function call and O(n) search of the base classes.
  The check is done in the various Py*_Check macros rather than calling
  PyType_IsSubtype().

  All the bits are set in tp_flags when the type is declared
  in the Objects/*object.c files because PyType_Ready() is not called
  for all the types.  Should PyType_Ready() be called for all types?
  If so and the change is made, the changes to the Objects/*object.c files
  can be reverted (remove setting the tp_flags).  Objects/typeobject.c
  would also have to be modified to add conditions
  for Py*_CheckExact() in addition to each the PyType_IsSubtype check.

  SF patch #1630975: Fix crash when replacing sys.stdout in sitecustomize

  When running the interpreter in an environment that would cause it to set
  stdout/stderr/stdin's encoding, having a sitecustomize that would replace
  them with something other than PyFile objects would crash the interpreter.
  Fix it by simply ignoring the encoding-setting for non-files.

  This could do with a test, but I can think of no maintainable and portable
  way to test this bug, short of adding a sitecustomize.py to the buildsystem
  and have it always run with it (hmmm....)

Neal Norwitz ca810467a4 Get rid of more coerce cruft (really check in this time :-) 2006-08-29 07:57:59 +00:00
Guido van Rossum 47b9ff6ba1 Restructure comparison dramatically. There is no longer a default
*ordering* between objects; there is only a default equality test
(defined by an object being equal to itself only).  Read the comment
in object.c.  The current implementation never uses a three-way
comparison to compute a rich comparison, but it does use a rich
comparison to compute a three-way comparison.  I'm not quite done
ripping out all the calls to PyObject_Compare/Cmp, or replacing
tp_compare implementations with tp_richcompare implementations;
but much of that has happened (to make most unit tests pass).

The following tests still fail, because I need help deciding
or understanding:

test_codeop -- depends on comparing code objects
test_datetime -- need Tim Peters' opinion
test_marshal -- depends on comparing code objects
test_mutants -- need help understanding it

The problem with test_codeop and test_marshal is this: these tests
compare two different code objects and expect them to be equal.
Is that still a feature we'd like to support?  I've temporarily
removed the comparison and hash code from code objects, so they
use the default (equality by pointer only) comparison.

For the other two tests, run them to see for yourself.
(There may be more failing test with "-u all".)

A general problem with getting lots of these tests to pass is
the reality that for object types that have a natural total ordering,
implementing __cmp__ is much more convenient than implementing
__eq__, __ne__, __lt__, and so on.  Should we go back to allowing
__cmp__ to provide a total ordering?  Should we provide some other
way to implement rich comparison with a single method override?
Alex proposed a __key__() method; I've considered a __richcmp__()
method.  Or perhaps __cmp__() just shouldn't be killed off...
2006-08-24 00:41:19 +00:00
Guido van Rossum 389381564c Change the way __hash__ is inherited; when __eq__ or __cmp__ is overridden
but __hash__ is not, set __hash__ explicitly to None (and tp_hash to NULL).
All unit tests pass now!

Thomas Wouters 00ee7baf49 Merge current trunk into p3yk. This includes the PyNumber_Index API change,
which unfortunately means the errors from the bytes type change somewhat:

bytes([300]) still raises a ValueError, but bytes([10**100]) now raises a
TypeError (either that, or bytes(1.0) also raises a ValueError --
PyNumber_AsSsize_t() can only raise one type of exception.)

  Even though _Py_Mangle() isn't truly public anyone can call it and
  there was no verification that privateobj was a PyString.  If it wasn't
  a string, this could have allowed a NULL pointer to creep in below and crash.

  I wonder if this should be PyString_CheckExact?  Must identifiers be strings
  or can they be subclasses?

  test_signal:  Signal handling on the Tru64 buildbot
  appears to be utterly insane.  Plug some theoretical
  insecurities in the test script:

  - Verify that the SIGALRM handler was actually installed.

  - Don't call alarm() before the handler is installed.

  - Move everything that can fail inside the try/finally,
    so the test cleans up after itself more often.

  - Try sending all the expected signals in
    force_test_exit(), not just SIGALRM.  Since that was
    fixed to actually send SIGALRM (instead of invisibly
    dying with an AttributeError), we've seen that sending
    SIGALRM alone does not stop this from hanging.

  - Move the "kill the child" business into the finally
    clause, so the child doesn't survive test failure
    to send SIGALRM to other tests later (there are also
    baffling SIGALRM-related failures in test_socket).

  - Cancel the alarm in the finally clause -- if the
    test dies early, we again don't want SIGALRM showing
    up to confuse a later test.

  Alas, this still relies on timing luck wrt the spawned
  script that sends the test signals, but it's hard to see
  how waiting for seconds can so often be so unlucky.

  test_threadedsignals:  curiously, this test never fails
  on Tru64, but doesn't normally signal SIGALRM.  Anyway,
  fixed an obvious (but probably inconsequential) logic
  error.

  Ah, fudge.  One of the prints here actually "shouldn't be"
  protected by "if verbose:", which caused the test to fail on

  Note that I deliberately didn't convert this to unittest yet,
  because I expect it would be even harder to debug this on Tru64
  after conversion.

  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.

  ctypes instances no longer have the internal and undocumented

  the type's stgdict.

  In the 'from_param' class methods, try the _as_parameter_ attribute if

http://mail.python.org/pipermail/python-dev/2006-April/064051.html

Hye-Shik Chang promised to look for a fix, so no need to fix it here. The
tests that are expected to break are:

test_codecencodings_cn
test_codecencodings_hk
test_codecencodings_jp
test_codecencodings_kr
test_codecencodings_tw
test_codecs

though, so I believe merging is the right thing to do anyway.

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 *.

Rewrote Py_RETURN_{NONE, TRUE, FALSE} to expand to comma expressions
rather than "do {} while(0)" thingies.  The OP complained because he
likes using MS /W4 sometimes, and then all his uses of these things
generate nuisance warnings about testing a constant expression (in
the "while(0)" part).  Comma expressions don't have this problem
(although it's a lucky accident that comma expressions suffice for these
macros!).

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
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.

2002-11-17 17:52:44 +00:00
Guido van Rossum febd61dc02 A modest speedup of object deallocation. call_finalizer() did rather
a lot of work: it had to save and restore the current exception around
a call to lookup_maybe(), because that could fail in rare cases, and
most objects don't have a __del__ method, so the whole exercise was
usually a waste of time.  Changed this to cache the __del__ method in
the type object just like all other special methods, in a new slot
tp_del.  So now subtype_dealloc() can test whether tp_del is NULL and
skip the whole exercise if it is.  The new slot doesn't need a new
flag bit: subtype_dealloc() is only called if the type was dynamically
allocated by type_new(), so it's guaranteed to have all current slots.
Types defined in C cannot fill in tp_del with a function of their own,
so there's no corresponding "wrapper".  (That functionality is already
available through tp_dealloc.)

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.
2002-07-17 16:30:39 +00:00
Tim Peters 3459251d5a object.h special-build macro minefield: renamed all the new lexical
helper macros to something saner, and used them appropriately in other
files too, to reduce #ifdef blocks.

classobject.c, instance_dealloc():  One of my worst Python Memories is
trying to fix this routine a few years ago when COUNT_ALLOCS was defined
but Py_TRACE_REFS wasn't.  The special-build code here is way too
complicated.  Now it's much simpler.  Difference:  in a Py_TRACE_REFS
build, the instance is no longer in the doubly-linked list of live
objects while its __del__ method is executing, and that may be visible
via sys.getobjects() called from a __del__ method.  Tough -- the object
is presumed dead while its __del__ is executing anyway, and not calling
_Py_NewReference() at the start allows enormous code simplification.

typeobject.c, call_finalizer():  The special-build instance_dealloc()
pain apparently spread to here too via cut-'n-paste, and this is much
simpler now too.  In addition, I didn't understand why this routine
was calling _PyObject_GC_TRACK() after a resurrection, since there's no
plausible way _PyObject_GC_UNTRACK() could have been called on the
object by this point.  I suspect it was left over from pasting the
instance_delloc() code.  Instead asserted that the object is still
tracked.  Caution:  I suspect we don't have a test that actually
exercises the subtype_dealloc() __del__-resurrected-me code.
2002-07-11 06:23:50 +00:00
Tim Peters 57f4ddd6c1 Uglified the new Py_REF_DEBUG (etc) lexical helper macro definitions so
that their uses can be prettier.  I've come to despise the names I picked
for these things, though, and expect to change all of them -- I changed
a bunch of other files to use them (replacing #ifdef blocks), but the
names were so obscure out of context that I backed that all out again.
2002-07-10 06:34:15 +00:00
Tim Peters 7c321a80f9 The Py_REF_DEBUG/COUNT_ALLOCS/Py_TRACE_REFS macro minefield: added
more trivial lexical helper macros so that uses of these guys expand
to nothing at all when they're not enabled.  This should help sub-
standard compilers that can't do a good job of optimizing away the
previous "(void)0" expressions.

Py_DECREF:  There's only one definition of this now.  Yay!  That
was that last one in the family defined multiple times in an #ifdef
maze.

Py_FatalError():  Changed the char* signature to const char*.

_Py_NegativeRefcount():  New helper function for the Py_REF_DEBUG
expansion of Py_DECREF.  Calling an external function cuts down on
the volume of generated code.  The previous inline expansion of abort()
didn't work as intended on Windows (the program often kept going, and
the error msg scrolled off the screen unseen).  _Py_NegativeRefcount
calls Py_FatalError instead, which captures our best knowledge of
how to abort effectively across platforms.
2002-07-09 02:57:01 +00:00
Tim Peters 4be93d0e84 Rearranged and added comments to object.h, to clarify many things

Vastly reduced the nesting level and redundancy of #ifdef-ery.
Took a light stab at repairing comments that are no longer true.

sys_gettotalrefcount():  Changed to enable under Py_REF_DEBUG.
It was enabled under Py_TRACE_REFS, which was much heavier than
necessary.  sys.gettotalrefcount() is now available in a
Py_REF_DEBUG-only build.

mechanism is no longer evil:  it no longer plays dangerous games with
the type pointer or refcounts, and objects in extension modules can play
along too without needing to edit the core first.

Rewrote all the comments to explain this, and (I hope) give clear
guidance to extension authors who do want to play along.  Documented
all the functions.  Added more asserts (it may no longer be evil, but
it's still dangerous <0.9 wink>).  Rearranged the generated code to
make it clearer, and to tolerate either the presence or absence of a
semicolon after the macros.  Rewrote _PyTrash_destroy_chain() to call
tp_dealloc directly; it was doing a Py_DECREF again, and that has all
sorts of obscure distorting effects in non-release builds (Py_DECREF
was already called on the object!).  Removed Christian's little "embedded
change log" comments -- that's what checkin messages are for, and since
it was impossible to correlate the comments with the code that changed,
I found them merely distracting.

Tim Peters 943382c8e5 Removed WITH_CYCLE_GC #ifdef-ery. Holes:

Neil Schemenauer f6d1ea1749 Change the type of the tp_free from 'destructor' to 'freefunc'. 2002-04-12 01:57:06 +00:00
Guido van Rossum 77f6a65eb0 Add the 'bool' type and its values 'False' and 'True', as described in
PEP 285.  Everything described in the PEP is here, and there is even
some documentation.  I had to fix 12 unit tests; all but one of these
were printing Boolean outcomes that changed from 0/1 to False/True.
(The exception is test_unicode.py, which did a type(x) == type(y)
style comparison.  I could've fixed that with a single line using
issubtype(x, type(y)), but instead chose to be explicit about those
places where a bool is expected.

Still to do: perhaps more documentation; change standard library
modules to return False/True from predicates.
2002-04-03 22:41:51 +00:00
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
Tim Peters 3abca127fe SF bug #475327: type() produces incorrect error msg
object.h:  Added PyType_CheckExact macro.

typeobject.c, type_new():

+ Use the new macro.
+ Assert that the arguments have the right types rather than do incomplete
  runtime checks "sometimes".
+ If this isn't the 1-argument flavor() of type, and there aren't 3 args
  total, produce a "types() takes 1 or 3 args" msg before
  PyArg_ParseTupleAndKeywords produces a "takes exactly 3" msg.

Guido van Rossum 687ae00460 Get rid of __defined__ and tp_defined -- there's no need to
distinguish __dict__ and __defined__ any more.  In the C structure,
tp_cache takes its place -- but this hasn't been implemented yet.
2001-10-15 22:03:32 +00:00
Guido van Rossum 2f3ca6eeb6 Completely get rid of __dynamic__ and the corresponding
Py_TPFLAGS_DYNAMICTYPE bit.  There is no longer a performance benefit,
and I don't really see the use case any more.
2001-10-15 21:05:10 +00:00
Guido van Rossum 1c45073aba Keep track of a type's subclasses (subtypes), in tp_subclasses, which
is a list of weak references to types (new-style classes).  Make this
accessible to Python as the function __subclasses__ which returns a
list of types -- we don't want Python programmers to be able to
manipulate the raw list.

In order to make this possible, I also had to add weak reference
support to type objects.

This will eventually be used together with a trap on attribute
assignment for dynamic classes for a major speed-up without losing the
dynamic properties of types: when a __foo__ method is added to a
class, the class and all its subclasses will get an appropriate tp_foo
slot function.
2001-10-08 15:18:27 +00:00
Fred Drake b3f0d349b6 PyObject_ClearWeakRefs() is now a real function instead of a function pointer;
the implementation is in Objects/weakrefobject.c.
2001-10-05 21:58:11 +00:00
Guido van Rossum 048eb75c2d Add Garbage Collection support to new-style classes (not yet to their
instances).

Also added GC support to various auxiliary types: super, property,
descriptors, wrappers, dictproxy.  (Only type objects have a tp_clear
field; the other types are.)

One change was necessary to the GC infrastructure.  We have statically
allocated type objects that don't have a GC header (and can't easily
be given one) and heap-allocated type objects that do have a GC
header.  Giving these different metatypes would be really ugly: I
tried, and I had to modify pickle.py, cPickle.c, copy.py, add a new
invent a new name for the new metatype and make it a built-in, change
affected tests...  In short, a mess.  So instead, we add a new type
slot tp_is_gc, which is a simple Boolean function that determines
whether a particular instance has GC headers or not.  This slot is
only relevant for types that have the (new) GC flag bit set.  If the
tp_is_gc slot is NULL (by far the most common case), all instances of
the type are deemed to have GC headers.  This slot is called by the
PyObject_IS_GC() macro (which is only used twice, both times in
gcmodule.c).

I also changed the extern declarations for a bunch of GC-related
functions (_PyObject_GC_Del etc.): these always exist but objimpl.h
only declared them when WITH_CYCLE_GC was defined, but I needed to be
able to reference them without #ifdefs.  (When WITH_CYCLE_GC is not
defined, they do the same as their non-GC counterparts anyway.)
2001-10-02 21:24:57 +00:00
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.
2001-09-20 20:46:19 +00:00
Guido van Rossum ab3b0343b8 Hopefully fix 3-way comparisons. This unfortunately adds yet another
hack, and it's even more disgusting than a PyInstance_Check() call.
If the tp_compare slot is the slot used for overrides in Python,
it's always called.

Add some tests that show what should work too.
2001-09-18 20:38:53 +00:00

2001-08-10 17:37:02 +00:00
Guido van Rossum 4668b000a1 Implement PEP 238 in its (almost) full glory.
This introduces:

- A new operator // that means floor division (the kind of division
  where 1/2 is 0).

- The "future division" statement ("from __future__ import division)
  which changes the meaning of the / operator to implement "true
  division" (where 1/2 is 0.5).

- New overloadable operators __truediv__ and __floordiv__.

- New slots in the PyNumberMethods struct for true and floor division,
  new abstract APIs for them, new opcodes, and so on.

I emphasize that without the future division statement, the semantics
of / will remain unchanged until Python 3.0.

Not yet implemented are warnings (default off) when / is used with int
or long arguments.

This has been on display since 7/31 as SF patch #443474.

Flames to /dev/null.

Guido van Rossum 213c7a6aa5 Mondo changes to the iterator stuff, without changing how Python code
sees it (test_iter.py is unchanged).

- Added a tp_iternext slot, which calls the iterator's next() method;
  this is much faster for built-in iterators over built-in types
  such as lists and dicts, speeding up pybench's ForLoop with about
  25% compared to Python 2.1.  (Now there's a good argument for
  iterators. ;-)

- Renamed the built-in sequence iterator SeqIter, affecting the C API
  functions for it.  (This frees up the PyIter prefix for generic
  iterator operations.)

- Added PyIter_Check(obj), which checks that obj's type has a
  tp_iternext slot and that the proper feature flag is set.

- Added PyIter_Next(obj) which calls the tp_iternext slot.  It has a
  somewhat complex return condition due to the need for speed: when it
  returns NULL, it may not have set an exception condition, meaning
  the iterator is exhausted; when the exception StopIteration is set
  (or a derived exception class), it means the same thing; any other
  exception means some other error occurred.

Tim Peters 4826a894c5 Close SF bug 110826: a complaint about the way Python #define'd NULL.
It's hard to sort out what the bug was, exactly.  So, Big Hammer:

1. Python shouldn't be in the business of #define'ing NULL, period.
2. Users of the Python C API shouldn't be in the business of not including
   Python.h, period.

Hence:

1. Removed all #define's of NULL in Python source code (pyport.h and
   object.h).
2. Since we're *relying* on stdio.h defining NULL, put an #error in
   Python.h after its #include of stdio.h if NULL isn't defined then.

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 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.

This patch modifies the type structures of objects that

Guido van Rossum e92e610a9e Christian Tismer -- total rewrite on trashcan code.
Improvements:
- does no longer need any extra memory
- has no relationship to tstate
- works in debug mode
- can easily be modified for free threading (hi Greg:)

Side effects:
Trashcan does change the order of object destruction.
Prevending that would be quite an immense effort, as
my attempts have shown. This version works always
the same, with debug mode or not. The slightly
changed destruction order should therefore be no problem.

Algorithm:
While the old idea of delaying the destruction of some
obejcts at a certain recursion level was kept, we now
no longer aloocate an object to hold these objects.
The delayed objects are instead chained together
via their ob_type field. The type is encoded via
ob_refcnt. When it comes to the destruction of the
chain of waiting objects, the topmost object is popped
off the chain and revived with type and refcount 1,
then it gets a normal Py_DECREF.

I am confident that this solution is near optimum
for minimizing side effects and code bloat.

Guido van Rossum d724b23420 Christian Tismer's "trashcan" patch:
Added wrapping macros to dictobject.c, listobject.c, tupleobject.c,

on stack overflow. Macros and functions in object.c, object.h.
The method is an "elevator destructor" that turns cascading

Guido van Rossum 36eef3c173 Changes by Greg Stein (code) and GvR (design).
Add a new member to the PyBufferProcs struct, bf_getcharbuffer.  For
backward compatibility, this member should only be used (this includes
testing for NULL!) when the flag Py_TPFLAGS_HAVE_GETCHARBUFFER is set
in the type structure, below.  Note that if its flag is not set, we
may be looking at an extension module compiled for 1.5.1, which will
have garbage at the bf_getcharbuffer member (because the struct wasn't
as long then).  If the flag is one, the pointer may still be NULL.
The function found at this member is used in a similar manner as
bf_getreadbuffer, but it is known to point to 8-bit character data.
(See discussion in getargs.c checked in later.)

As a general feature for extending the type structure and the various
structures that (may) hang off it in a backwards compatible way, we
rename the tp_xxx4 "spare" slot to tp_flags.  In 1.5.1 and before,
this slot was always zero.  In 1.5.1, it may contain various flags
indicating extra fields that weren't present in 1.5.1.  The only flag
defined so far is for the bf_getcharbuffer member of the PyBufferProcs
struct.

Note that the new spares (tp_xxx5 - tp_xxx8), once they become used,
should also be protected by a flag (or flags) in tp_flags.

Guido van Rossum d0c87ee6c4 Oops, another forgotten renaming: varobject -> PyVarObject. 1997-05-15 21:31:03 +00:00
Guido van Rossum fdf95dd525 Checkin of Jack's buffer mods.
Not really checked, but didn't fail any tests either...
1997-05-05 22:15:02 +00:00

1996-05-22 16:33:22 +00:00
Guido van Rossum 454674d5db add forgotten PyObject_SetAttrString 1995-07-26 17:53:29 +00:00
Guido van Rossum 884afd654a keyword arguments and faster function calls 1995-07-18 14:21:06 +00:00
Sjoerd Mullender 107c747009 DL_IMPORT needs an argument. 1995-04-25 11:53:24 +00:00
Jack Jansen 5dbc7231a0 DL_IMPORT macro was called in a funny way (and MW barfed on it) 1995-04-23 22:06:05 +00:00
Sjoerd Mullender 91e7a0bd2a Also count UNREF's as freeing an object (only relevant when
COUNT_ALLOCS is defined).
1995-04-06 13:47:48 +00:00
Guido van Rossum 6f9e433ab3 fix dusty debugging macros 1995-03-29 16:57:48 +00:00
Guido van Rossum 051ab123b4 make the type a parameter of the DL_IMPORT macro, for Borland C 1995-02-27 10:17:52 +00:00
Guido van Rossum 57836fe998 change in staticforward -- added statichere 1995-02-21 21:06:10 +00:00
Guido van Rossum b13afdd6f4 added PyObject_IsTrue & PyCallable_Check to object interface 1995-02-17 15:01:21 +00:00
Guido van Rossum 938178283c new names for lots of new functions 1995-01-17 16:01:01 +00:00
Guido van Rossum caa6380886 The great renaming, phase two: all header files have been updated to
use the new names exclusively, and the linker will see the new names.
Files that import "Python.h" also only see the new names.  Files that
import "allobjects.h" will continue to be able to use the old names,
due to the inclusion (in allobjects.h) of "rename2.h".
1995-01-12 11:45:45 +00:00
Guido van Rossum 6fde390655 new tp_str and tp_doc members in type object 1995-01-07 10:32:04 +00:00
Guido van Rossum 5799b52008 Added 1995 copyright.
object.h: made sizes and refcnts signed ints.
stringobject.h: make getstrsize() signed int.
methodobject.h: add METH_VARARGS and METH_FREENAME flag bit definitions.

Guido van Rossum e89bc75048 Changes for dynamic linking under NT 1994-08-18 16:18:13 +00:00
Guido van Rossum 75abc6392b * Objects/{int,long,float}object.c, Include/object.h,
Python/bltinmodule.c: mods by Andrew Kuchling to implement
	pow(x,y,z) == pow(x,y)%z, but without incurring overflow
1994-08-09 13:21:54 +00:00
Guido van Rossum b6775db241 Merge alpha100 branch back to main trunk 1994-08-01 11:34:53 +00:00
Guido van Rossum c600411755 * mpzmodule.c: removed redundant mpz_print function.
* object.[ch], bltinmodule.c, fileobject.c: changed str() to call
  strobject() which calls an object's __str__ method if it has one.
  strobject() is also called by writeobject() when PRINT_RAW is passed.
* ceval.c: rationalize code for PRINT_ITEM (no change in function!)
* funcobject.c, codeobject.c: added compare and hash functionality.
  Functions with identical code objects and the same global dictionary are
  equal.  Code objects are equal when their code, constants list and names
  list are identical (i.e. the filename and code name don't count).
  (hash doesn't work yet since the constants are in a list and lists can't
  be hashed -- suppose this should really be done with a tuple now we have
  resizetuple!)
1993-11-05 10:22:19 +00:00
Sjoerd Mullender a9c3c22c33 * Extended X interface: pixmap objects, colormap objects visual objects,
image objects, and lots of new methods.
* Added counting of allocations and deallocations of builtin types if
  COUNT_ALLOCS is defined.  Had to move calls to NEWREF down in some
  files.
* Bug fix in sorting lists.
1993-10-11 12:54:31 +00:00
Guido van Rossum a3309960a5 * Added support for X11 modules.
* Makefile: change location of FORMS library.
* posixmodule.c: turn #if 0 into #ifdef MSDOS (stuff in unistd.h or not)
* Almost all .h files: added CPP magic to avoid duplicate inclusions and
  to support inclusion from C++.
1993-07-28 09:05:47 +00:00
Guido van Rossum ed18fdc9fc * accessobject.c (ownercheck): allow a base class access to protected
objects of its derived classes; allow anything that has an attribute
  named "__privileged__" access to anything.
* object.[ch]: added hasattr() -- test whether getattr() will succeed.
1993-07-11 19:55:34 +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
