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.

Georg Brandl d5b635f196 Make Py3k warnings consistent w.r.t. punctuation; also respect the
EOL 80 limit and supply more alternatives in warning messages.

Steven Bethard ae42f33cdf Add py3k warnings for object, type, cell and dict comparisons. This should resolve issue2342 and partly resolve issue2373. 2008-03-18 17:26:10 +00:00
Christian Heimes 09bde04154 Use PY_FORMAT_SIZE_T instead of z for string formatting. Thanks Neal. 2008-02-24 12:26:16 +00:00

Christian Heimes f75dbef208 Deallocate content of the dict free list on interpreter shutdown 2008-02-08 00:11:31 +00:00
Christian Heimes b4ee4a16f4 Added some statistics code to dict and list object code. I wanted to test how a larger freelist affects the reusage of freed objects. Contrary to my gut feelings 80 objects is more than fine for small apps. I haven't profiled a large app yet. 2008-02-07 17:15:30 +00:00
Christian Heimes 5b970ad483 Unified naming convention for free lists and their limits. All free lists
in Object/ are named ``free_list``, the counter ``numfree`` and the upper
limit is a macro ``PyName_MAXFREELIST`` inside an #ifndef block.

The chances should make it easier to adjust Python for platforms with
less memory, e.g. mobile phones.

Raymond Hettinger 3dbd4c536d Changes 54857 and 54840 broke code and were reverted in Py2.5 just before
it was released, but that reversion never made it to the Py2.6 head.

Christian Heimes e93237dfcc #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE and Py_REFCNT. Macros for b/w compatibility are available. 2007-12-19 02:37:44 +00:00
Raymond Hettinger fd7ed407d7 Give meaning to the oparg for BUILD_MAP: estimated size of the dictionary.
Allows dictionaries to be pre-sized (upto 255 elements) saving time lost
to re-sizes with their attendant mallocs and re-insertions.

Has zero effect on small dictionaries (5 elements or fewer), a slight
benefit for dicts upto 22 elements (because they had to resize once
anyway), and more benefit for dicts upto 255 elements (saving multiple
resizes during the build-up and reducing the number of collisions on
the first insertions).  Beyond 255 elements, there is no addional benefit.

Brett Cannon 77ae87c11e Remove file-level typedefs that were inconsistently used throughout the file.
Just move over to the public API names.

Neal Norwitz 8b2bfbc198 Add -3 option to the interpreter to warn about features that are
deprecated and will be changed/removed in Python 3.0.

This patch is mostly from Anthony.  I tweaked some format and added
a little doc.

Raymond Hettinger 0bbbfc4c0b Extend work on rev 52962 and 53829 eliminating redundant PyObject_Hash() calls and fixing set/dict interoperability. 2007-03-20 21:27:24 +00:00
Neal Norwitz ee3a1b5244 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.

the tuple isn't used as the "exception arguments tuple".

Neal Norwitz a5ccda95f2 Fix warnings with HP's C compiler. It doesn't recognize that infinite
loops are, um, infinite.  These conditions should not be able to happen.

Will backport.

PyThreadState_GET() complains if the tstate is NULL, but only in debug mode.

Tim Peters d770ebd286 Armin committed his patch while I was reviewing it (I'm sure
he didn't know this), so merged in some changes I made during
review.  Nothing material apart from changing a new `mask` local
from int to Py_ssize_t.  Mostly this is repairing comments that
were made incorrect, and adding new comments.  Also a few
minor code rewrites for clarity or helpful succinctness.

Tim Peters 33f4a6a31a dict_print(): So that Neal & I don't spend the rest of
our lives taking turns rewriting code that works ;-),
get rid of casting illusions by declaring a new variable
with the obvious type.
