* Make weak references subclassable:Fred Drake2004-07-021-1/+6
| | | | | | | | | | | | | | | | | | | | | | - weakref.ref and weakref.ReferenceType will become aliases for each other - weakref.ref will be a modern, new-style class with proper __new__ and __init__ methods - weakref.WeakValueDictionary will have a lighter memory footprint, using a new weakref.ref subclass to associate the key with the value, allowing us to have only a single object of overhead for each dictionary entry (currently, there are 3 objects of overhead per entry: a weakref to the value, a weakref to the dictionary, and a function object used as a weakref callback; the weakref to the dictionary could be avoided without this change) - a new macro, PyWeakref_CheckRefExact(), will be added - PyWeakref_CheckRef() will check for subclasses of weakref.ref This closes SF patch #983019.
* SF Bug #215126: Over restricted type checking on eval() functionRaymond Hettinger2004-07-021-1/+1
| | | | | | The builtin eval() function now accepts any mapping for the locals argument. Time sensitive steps guarded by PyDict_CheckExact() to keep from slowing down the normal case. My timings so no measurable impact.

* SF patch 876130: add C API to datetime module, from Anthony Tuininga.Tim Peters2004-06-201-0/+95
| | | | | | The LaTeX is untested (well, so is the new API, for that matter). Note that I also changed NULL to get spelled consistently in concrete.tex. If that was a wrong thing to do, Fred should yell at me.
* Bug 975996: Add _PyTime_DoubleToTimet to C APITim Peters2004-06-201-0/+23
| | | | | | | | | | | New include file timefuncs.h exports private API function _PyTime_DoubleToTimet() from timemodule.c. timemodule should export some other functions too (look for painful bits in datetimemodule.c). Added insane-argument checking to datetime's assorted fromtimestamp() and utcfromtimestamp() methods. Added insane-argument tests of these to test_datetime, and insane-argument tests for ctime(), localtime() and gmtime() to test_time.

* SF patch #872326: Generator expression implementationRaymond Hettinger2004-05-192-18/+25
| | | | | | | | | | | | | | (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.

* SF patch #910929: Optimize list comprehensionsRaymond Hettinger2004-03-071-0/+1
| | | | | 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.
* * Optimized list appends and pops by making fewer calls the underlying systemRaymond Hettinger2004-02-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.)

* At 2.2, the Py<type>_Check() family of API functions (macros) changedAndrew MacIntyre2003-12-261-0/+1
| | | | | | | | | | | | 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.
