* Issue #29300: Use Argument Clinic for getting struct object from the format.Serhiy Storchaka2017-02-041-65/+52
|
* Rename struct.unpack() 2nd parameter to "buffer"Victor Stinner2017-02-021-4/+4
| | | | | | | | | | Issue #29300: Rename struct.unpack() second parameter from "inputstr" to "buffer", and use the Py_buffer type. Fix also unit tests on struct.unpack() which passed a Unicode string instead of a bytes string as struct.unpack() second parameter. The purpose of test_trailing_counter() is to test invalid format strings, not to test the buffer parameter.
* Issue #29300: Convert _struct module to Argument ClinicVictor Stinner2017-02-021-226/+246
| | | | | | | | | | | | | | | | | | | | | | | | | * The struct module now requires contiguous buffers. * Convert most functions and methods of the _struct module to Argument Clinic * Use "Py_buffer" type for the "buffer" argument. Argument Clinic is responsible to create and release the Py_buffer object. * Use "PyStructObject *" type for self to avoid explicit conversions. * Add an unit test on the _struct.Struct.unpack_from() method to test passing arguments as keywords. * Rephrase docstrings. * Rename "fmt" argument to "format" in docstrings and the documentation. As a side effect, functions and methods which used METH_VARARGS calling convention like struct.pack() now use the METH_FASTCALL calling convention which avoids the creation of temporary tuple to pass positional arguments and so is faster. For example, struct.pack("i", 1) becomes 1.56x faster (-36%):: $ ./python -m perf timeit \ -s 'import struct; pack=struct.pack' 'pack("i", 1)' \ --compare-to=../default-ref/python Median +- std dev: 119 ns +- 1 ns -> 76.8 ns +- 0.4 ns: 1.56x faster (-36%) Significant (t=295.91) Patch co-written with Serhiy Storchaka.

* 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.
