* Issue #29421: Make int.to_bytes() and int.from_bytes() slightly fasterSerhiy Storchaka2017-02-021-4/+7

* Backed out changeset b9c9691c72c5Victor Stinner2016-12-041-1/+2
| | | | | | 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 Stinner2016-12-011-2/+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.

|/ / | | | | | | | | | | | | | | Optimize bytes.__mod__(args) for integere formats: %d (%i, %u), %o, %x and %X. _PyBytesWriter is now used to format directly the integer into the writer buffer, instead of using a temporary bytes object. Formatting is between 30% and 50% faster on a microbenchmark.

* | #16518: Bring error messages in harmony with docs ("bytes-like object")R David Murray2014-10-051-3/+1
| | | | | | | | | | | | | | | | | | | | Some time ago we changed the docs to consistently use the term 'bytes-like object' in all the contexts where bytes, bytearray, memoryview, etc are used. This patch (by Ezio Melotti) completes that work by changing the error messages that previously reported that certain types did "not support the buffer interface" to instead say that a bytes-like object is required. (The glossary entry for bytes-like object references the discussion of the buffer protocol in the docs.)
