Mark Dickinson <dicki...@gmail.com> added the comment: Patch that unoutrages Python attached: it allows shift counts of up to sys.maxsize in both left shift and right shift. I don't have a test for this, since the only tests I can think of (e.g. actually doing 1 << (2**31)) require > 270Mb of RAM, and that may be too much for some of the buildbots. (We could add a 'largemem' special resource to regrtest, I suppose, but it doesn't seem worth the effort just for this.)
This patch doesn't solve the OPs problem, though. The PyLong code *could* be modified to accept larger shift counts (e.g., up to 8*PY_SSIZE_T_MAX; beyond this you'll get a MemoryError anyway), but this seems like a significant effort for little gain. It might make more sense for right shifting, though. Anyway, I'd definitely call that a feature request. ---------- assignee: -> mark.dickinson keywords: +patch Added file: http://bugs.python.org/file16783/no_outrage.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue8259> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
