* Implementation of patch 869468David Ascher2004-02-185-16/+264
| | | | | | | | | | | | | | | Allow the user to create Tkinter.Tcl objects which are just like Tkinter.Tk objects except that they do not initialize Tk. This is useful in circumstances where the script is being run on machines that do not have an X server running -- in those cases, Tk initialization fails, even if no window is ever created. Includes documentation change and tests. Tested on Linux, Solaris and Windows. Reviewed by Martin von Loewis.

Results: * list.extend() no longer creates an intermediate tuple except to handle the special case of x.extend(x). The saves memory and time. * list.extend(x) runs about the same x is a list or tuple, a little faster when x is an iterable not defining __len__, and twice as fast when x is an iterable defining __len__. * the code is about 15 lines shorter and no longer duplicates functionality.

* Fine tune the speed/space trade-off for overallocating small lists.Raymond Hettinger2004-02-143-12/+7
| | | | | | | | | | | | | | The Py2.3 approach overallocated small lists by up to 8 elements. The last checkin would limited this to one but slowed down (by 20 to 30%) the creation of small lists between 3 to 8 elements. This tune-up balances the two, limiting overallocation to 3 elements (significantly reducing space consumption from Py2.3) and running faster than the previous checkin. The first part of the growth pattern (0, 4, 8, 16) neatly meshes with allocators that trigger data movement only when crossing a power of two boundary. Also, then even numbers mesh well with common data alignments.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.)
