bpo-35444: Unify and optimize the helper for getting a builtin object. (GH-11047) 
This speeds up pickling of some iterators.

This fixes also error handling in pickling methods when fail to
look up builtin "getattr".

bpo-35081: Add Include/internal/pycore_object.h (GH-10640) 
Move _PyObject_GC_TRACK() and _PyObject_GC_UNTRACK() from
Include/objimpl.h to Include/internal/pycore_object.h.

bpo-35081: Rename internal headers (GH-10275) 
Rename Include/internal/ headers:

* pycore_hash.h -> pycore_pyhash.h
* pycore_lifecycle.h -> pycore_pylifecycle.h
* pycore_mem.h -> pycore_pymem.h
* pycore_state.h -> pycore_pystate.h

Add missing headers to Makefile.pre.in and PCbuild:

* pycore_condvar.h.
* pycore_hamt.h
* pycore_pyhash.h

bpo-35081: Add pycore_ prefix to internal header files (GH-10263) 
* Rename Include/internal/ header files:

  * pyatomic.h -> pycore_atomic.h
  * ceval.h -> pycore_ceval.h
  * condvar.h -> pycore_condvar.h
  * context.h -> pycore_context.h
  * pygetopt.h -> pycore_getopt.h
  * gil.h -> pycore_gil.h
  * hamt.h -> pycore_hamt.h
  * hash.h -> pycore_hash.h
  * mem.h -> pycore_mem.h
  * pystate.h -> pycore_state.h
  * warnings.h -> pycore_warnings.h

* PCbuild project, Makefile.pre.in, Modules/Setup: add the
  Include/internal/ directory to the search paths of header files.
* Update includes. For example, replace #include "internal/mem.h"
  with #include "pycore_mem.h".

Siddhesh Poyarekar 55edd0c185 bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. (GH-6030) 
METH_NOARGS functions need only a single argument but they are cast
into a PyCFunction, which takes two arguments.  This triggers an
invalid function cast warning in gcc8 due to the argument mismatch.
Fix this by adding a dummy unused argument.

Eric Snow 2ebc5ce42a bpo-30860: Consolidate stateful runtime globals. (#3397) 
* group the (stateful) runtime globals into various topical structs
* consolidate the topical structs under a single top-level _PyRuntimeState struct
* add a check-c-globals.py script that helps identify runtime globals

Other globals are excluded (see globals.txt and check-c-globals.py).

Issue #27809:

* Add _PyObject_FastCall(), _PyObject_CallNoArg() and _PyObject_CallArg1()
  macros calling _PyObject_FastCallDict()

Christian Heimes a22e8bdfd9 Added all PyTypeObjects to the appropriate header files. 
Before the patch a lot of internal types weren't available in the header files. The patch exposes the new iterators, views and some other types to all C modules. I've also renamed some of the types and tp_names.
 2007-11-29 22:35:39 +00:00
Christian Heimes f83be4e3f3 Added view and iterator types to collections / _abcoll 
I've also renamed several of the iterators to keep a consistent naming schema.

Thomas Wouters 49fd7fa443 Merge p3yk branch with the trunk up to revision 45595. This breaks a fair 
number of tests, all because of the codecs/_multibytecodecs issue described
here (it's not a Py3K issue, just something Py3K discovers):
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
test_multibytecodec

This merge fixes an actual test failure (test_weakref) in this branch,
though, so I believe merging is the right thing to do anyway.

Guido van Rossum 84b2bed435 Squash a few calls to the hideously expensive PyObject_CallObject(o,a) 
-- replace then with slightly faster PyObject_Call(o,a,NULL).  (The
difference is that the latter requires a to be a tuple; the former
allows other values and wraps them in a tuple if necessary; it
involves two more levels of C function calls to accomplish all that.)

Raymond Hettinger 48923c5533 Moved special case for tuples from iterobject.c to

Guido van Rossum 613bed3726 Make StopIteration a sink state. This is done by clearing out the 
object references (it_seq for seqiterobject, it_callable and
it_sentinel for calliterobject) when the end of the list is reached.

Also remove the next() methods -- one is supplied automatically by
PyType_Ready() because the tp_iternext slot is set.  That's a good
thing, because the implementation given here was buggy (it never
raised StopIteration).
