* Eliminate a big block of duplicate code in PySequence_List() byRaymond Hettinger2004-03-111-0/+1

* 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.
