Victor Stinner	dd431b32f4	PyLong_FromString(): fix Coverity CID 1424951 (#4738 ) Explicitly cast digits (Py_ssize_t) to double to fix the following false-alarm warning from Coverity: "fsize_z = digits * log_base_BASE[base] + 1;" CID 1424951: Incorrect expression (UNINTENDED_INTEGER_DIVISION) Dividing integer expressions "9223372036854775783UL" and "4UL", and then converting the integer quotient to type "double". Any remainder, or fractional part of the quotient, is ignored.	9 years ago
Serhiy Storchaka	29ba688034	bpo-31619: Fixed integer overflow in converting huge strings to int. (#3884 )	9 years ago
Sanyam Khurana	28b624825e	bpo-16055: Fixes incorrect error text for int('1', base=1000) (#4376 ) * bpo-16055: Fixes incorrect error text for int('1', base=1000) * bpo-16055: Address review comments	9 years ago
Serhiy Storchaka	9b6c60cbce	bpo-31979: Simplify transforming decimals to ASCII (#4336 ) in int(), float() and complex() parsers. This also speeds up parsing non-ASCII numbers by around 20%.	9 years ago
stratakis	e8b1965639	bpo-23699: Use a macro to reduce boilerplate code in rich comparison functions (GH-793)	9 years ago

Barry Warsaw	b2e5794870	bpo-31338 (#3374 ) * Add Py_UNREACHABLE() as an alias to abort(). * Use Py_UNREACHABLE() instead of assert(0) * Convert more unreachable code to use Py_UNREACHABLE() * Document Py_UNREACHABLE() and a few other macros.	9 years ago
Serhiy Storchaka	918403cfc3	bpo-29816: Shift operation now has less opportunity to raise OverflowError. (#680 ) ValueError always is raised rather than OverflowError for negative counts. Shifting zero with non-negative count always returns zero.	9 years ago

Serhiy Storchaka	58d23e6806	bpo-29695: Deprecated using bad named keyword arguments in builtings: (#486 ) int(), bool(), float(), list() and tuple(). Specify the value as a positional argument instead.	9 years ago

Victor Stinner	de4ae3d486	Backed out changeset b9c9691c72c5 Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs().	10 years ago
Victor Stinner	27580c1fb5	Replace PyObject_CallFunctionObjArgs() with fastcall * 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.	10 years ago
