* Fix typo and edit for clarity in the docstrings of sys.float_info. (GH-2251)Miss Islington (bot)2018-03-261-3/+2
| | | | | (cherry picked from commit 0301c9bdd1ebd788d1334cf3fe06c48f35bab0dc) Co-authored-by: Stefano Taschini <taschini@users.noreply.github.com>
* bpo-31979: Simplify transforming decimals to ASCII (#4336)Serhiy Storchaka2017-11-131-4/+3
| | | | | in int(), float() and complex() parsers. This also speeds up parsing non-ASCII numbers by around 20%.
* bpo-31373: remove overly strict float range checks (#3486)Benjamin Peterson2017-09-101-2/+2
| | | | | This undoes a853a8ba7850381d49b284295dd6f0dc491dbe44 except for the pytime.c parts. We want to continue to allow IEEE 754 doubles larger than FLT_MAX to be rounded into finite floats. Tests were added to very this behavior.

* Backed out changeset b9c9691c72c5Victor Stinner2016-12-041-1/+1
| | | | | | Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs().
* Replace PyObject_CallFunctionObjArgs() with fastcallVictor Stinner2016-12-011-1/+1
| | | | | | | | | | | | | | * PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func) * PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg) PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires extra work to "parse" C arguments to build a C array of PyObject*. _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack. This change is part of the fastcall project. The change on listsort() is related to the issue #23507.

| | | | | | | | | | | | | | | | This avoids possible buffer overreads when int(), float(), compile(), exec() and eval() are passed bytes-like objects. Similar code is removed from the complex() constructor, where it was not reachable. Patch by John Leitch, Serhiy Storchaka and Martin Panter.
