Hye-Shik Chang 974ed7cfa5 - SF #962502: Add two more methods for unicode type; width() and
iswide() for east asian width manipulation. (Inspired by David
Goodger, Reviewed by Martin v. Loewis)
- Move _PyUnicode_TypeRecord.flags to the end of the struct so that
no padding is added for UCS-4 builds. (Suggested by Martin v. Loewis)

Raymond Hettinger 354433a59d SF patch #872326: Generator expression implementation
(Code contributed by Jiwon Seo.)

The documentation portion of the patch is being re-worked and will be
checked-in soon.  Likewise, PEP 289 will be updated to reflect Guido's
rationale for the design decisions on binding behavior (as described in
in his patch comments and in discussions on python-dev).

The test file, test_genexps.py, is written in doctest format and is
meant to exercise all aspects of the the patch.  Further additions are
welcome from everyone.  Please stress test this new feature as much as
possible before the alpha release.

Hye-Shik Chang 77d9a3effa Patch #871657: Set EDOM for `nan' return values on FreeBSD and OpenBSD.

Nicholas Bastin a7604bf1b4 Moved tracebackobject to traceback.h, Closes SF Bug #497067 2004-03-21 18:37:23 +00:00
Skip Montanaro 6e098a15a3 compile.h and eval.h weren't being included which kept a fair bit of the
public API from being exposed by simply including Python.h (as recommended).

Raymond Hettinger 42bec93e5c Make PySequence_Fast_ITEMS public. (Thanks Skip.) 2004-03-12 16:38:17 +00:00
Raymond Hettinger c1e4f9dd92 Use a new macro, PySequence_Fast_ITEMS to factor out code common to
three recent optimizations.  Aside from reducing code volume, it
increases readability.
2004-03-12 08:04:00 +00:00
Raymond Hettinger 8ca92ae54c Eliminate a big block of duplicate code in PySequence_List() by
exposing _PyList_Extend().

Raymond Hettinger dd80f76265 SF patch #910929: Optimize list comprehensions
Add a new opcode, LIST_APPEND, and apply it to the code generation for
list comprehensions.  Reduces the per-loop overhead by about a third.
2004-03-07 07:31:06 +00:00
Raymond Hettinger 4bb9540dd6 * Optimized list appends and pops by making fewer calls the underlying system
realloc().  This is achieved by tracking the overallocation size in a new
  field and using that information to skip calls to realloc() whenever
  possible.

* Simplified and tightened the amount of overallocation.  For larger lists,
  this overallocates by 1/8th (compared to the previous scheme which ranged
  between 1/4th to 1/32nd over-allocation).  For smaller lists (n<6), the
  maximum overallocation is one byte (formerly it could be upto eight bytes).
  This saves memory in applications with large numbers of small lists.

* Eliminated the NRESIZE macro in favor of a new, static list_resize function
  that encapsulates the resizing logic.  Coverting this back to macro would
  give a small (under 1%) speed-up.  This was too small to warrant the loss
  of readability, maintainability, and de-coupling.

* Some functions using NRESIZE had grown unnecessarily complex in their
  efforts to bend to the macro's calling pattern.  With the new list_resize
  function in place, those other functions could be simplified.  That is
  being saved for a separate patch.

* The ob_item==NULL check could be eliminated from the new list_resize
  function.  This would entail finding each piece of code that sets ob_item
  to NULL and adding a new line to invalidate the overallocation tracking
  field.  Rather than impose a new requirement on other pieces of list code,
  it was preferred to leave the NULL check in place and retain the benefits
  of decoupling, maintainability and information hiding (only PyList_New()
  and list_sort() need to know about the new field).  This approach also
  reduces the odds of breaking an extension module.

(Collaborative effort by Raymond Hettinger, Hye-Shik Chang, Tim Peters,
 and Armin Rigo.)

Jeremy Hylton 87c1afa057 Fix name problem in previous checkin: Dict not List 2003-12-26 17:17:49 +00:00
Andrew MacIntyre e99990f9e1 At 2.2, the Py<type>_Check() family of API functions (macros) changed
semantics to include subtypes.  Most concrete object APIs then had
a Py<type>_CheckExact() macro added to test for an object's type
not including subtypes.

The PyDict_CheckExact() macro wasn't created at that time, so I've added
it for API completeness/symmetry - even though nobody has complained
about its absence in the time since 2.2 was released.

Not a backport candidate.

Andrew MacIntyre 6f3a24d0b3 reverting 2.29: the patch was Ok, but the commit msg wrong 2003-12-26 00:19:28 +00:00
Andrew MacIntyre 43e5711309 The semantics of PyList_Check() and PyDict_Check() changed at 2.2, along
with most other concrete object checks, but the docs weren't brought into
line.

PyList_CheckExact() was added at 2.2 but never documented.

backport candidate.

Tim Peters 0490fe96d8 Changed the UCHAR_MAX error msg a bit: we don't really assume anything
about "characters", we assume something about C's char type (which is
an integral type).
2003-12-22 18:10:51 +00:00
Skip Montanaro ac4ea13a3a There are places in Python which assume bytes have 8-bits. Formalize that a
bit by checking the value of UCHAR_MAX in Include/Python.h.  There was a
check in Objects/stringobject.c.  Remove that.  (Note that we don't define
UCHAR_MAX if it's not defined as the old test did.)

Raymond Hettinger bc0f2ab9bb Expose dict_contains() and PyDict_Contains() with is about 10% faster
than PySequence_Contains() and more clearly applicable to dicts.

ubiquitous.

Tim Peters 403a203223 SF bug 839548: Bug in type's GC handling causes segfaults.

This is a critical bugfix.
I'll backport to 2.3 maint, but not beyond that.  The bugs this fixes
have been there since weakrefs were introduced.

Brett Cannon 4b17e3993b Modify the Py_RETURN_* macros to be of the form ``do {...} while (0)`` in order
to handle situations like ``if (foo) Py_RETURN_NONE else ...``.
2003-10-19 22:58:11 +00:00
Brett Cannon 26b3a7b82c Modified the Py_RETURN_* macros by having the statements surrounded by {} in
order to prevent any unexpected surprises from someone using them in a
conditional without using curly braces (e.g., ``if (foo) Py_RETURN_TRUE``.
2003-10-19 21:31:43 +00:00
Brett Cannon d05235ec49 Defined macros Py_RETURN_(TRUE|FALSE|NONE) as helper functions for returning
the specified value.  All three Py_INCREF the singleton and then return it.
