New submission from Andrew I MacIntyre <[EMAIL PROTECTED]>: In r60567, support for compacting the int & float freelists was added with a function in the sys module to call the compaction routines.
Since then, other freelist clearing routines have been added to other types and are called from the collect() function in the gc module. The attached patch harmonises the in/float freelist compaction with the other freelist clearing mechanisms. It does away with the function in the sys module in favour of running the freelist clearing from gc.collect(). The signatures of the type specific freelist clearing routines have been brought into line with the other type freelist clearing routines, with the exception that they return the number of items _not_ free()ed, rather than the number of items free()ed. I took this approach to try and highlight the fact the current int/float freelist implementations don't use pymalloc and not all items will always be free()ed when the routine is called. This return is ignored when called from gc.collect() in any case. The patch includes doc updates and test updates to reflect the changes. It has been tested on FreeBSD 6.3, surviving a default test run with no unusual test failures as far as I can tell. It is not otherwise rigorously tested. The patch is against a trunk checkout that seems to be at r63156. Ideally this patch, or similar modifications, should be applied before the feature freeze for 2.6, so that freelist management is rationalised to one way to do it. ---------- assignee: christian.heimes components: Documentation, Interpreter Core, Tests files: freelist_mgt_cleanup.patch keywords: patch, patch messages: 66858 nosy: aimacintyre, christian.heimes priority: high severity: normal status: open title: cleanup of freelist management type: behavior versions: Python 2.6 Added file: http://bugs.python.org/file10331/freelist_mgt_cleanup.patch __________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue2862> __________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
