Change the parser and compiler to use PyMalloc. Only the files implementing processes that will request memory allocations small enough for PyMalloc to be a win have been changed, which are:- - Python/compile.c - Parser/acceler.c - Parser/node.c - Parser/parsetok.c This augments the aggressive overallocation strategy implemented by Tim Peters in PyNode_AddChild() [Parser/node.c], in reducing the impact of platform malloc()/realloc()/free() corner case behaviour. Such corner cases are known to be triggered by test_longexp and test_import. Jeremy Hylton, in accepting this patch, recommended this as a bugfix candidate for 2.2. While the changes to Python/compile.c and Parser/node.c backport easily (and could go in), the changes to Parser/acceler.c and Parser/parsetok.c require other not insignificant changes as a result of the differences in the memory APIs between 2.3 and 2.2, which I'm not in a position to work through at the moment. This is a pity, as the Parser/parsetok.c changes are the most important after the Parser/node.c changes, due to the size of the memory requests involved and their frequency. |
