* Issue #27213: Fixed different issues with reworked CALL_FUNCTION* opcodes.Serhiy Storchaka2016-09-111-1/+1
| | | | | | | | | | | * BUILD_TUPLE_UNPACK and BUILD_MAP_UNPACK_WITH_CALL no longer generated with single tuple or dict. * Restored more informative error messages for incorrect var-positional and var-keyword arguments. * Removed code duplications in _PyEval_EvalCodeWithName(). * Removed redundant runtime checks and parameters in _PyStack_AsDict(). * Added a workaround and enabled previously disabled test in test_traceback. * Removed dead code from the dis module.
* Add METH_FASTCALL calling conventionVictor Stinner2016-09-101-0/+24
| | | | | | | | | | | Issue #27810: Add a new calling convention for C functions: PyObject* func(PyObject *self, PyObject **args, Py_ssize_t nargs, PyObject *kwnames); Where args is a C array of positional arguments followed by values of keyword arguments. nargs is the number of positional arguments, kwnames are keys of keyword arguments. kwnames can be NULL.
* Issue #27810: Add _PyCFunction_FastCallKeywords()Victor Stinner2016-09-091-0/+26
| | | | | Use _PyCFunction_FastCallKeywords() in ceval.c: it allows to remove a lot of code from ceval.c which was only used to call C functions.
* Use Py_ssize_t type for number of argumentsVictor Stinner2016-08-241-2/+7
| | | | | Issue #27848: use Py_ssize_t rather than C int for the number of function positional and keyword arguments.
* _PyFunction_FastCallDict() supports keyword argsVictor Stinner2016-08-221-3/+3
| | | | | | | | Issue #27809: * Rename _PyFunction_FastCall() to _PyFunction_FastCallDict() * Rename _PyCFunction_FastCall() to _PyCFunction_FastCallDict() * _PyFunction_FastCallDict() now supports keyword arguments
* Add _PyObject_FastCall()Victor Stinner2016-08-191-0/+93
| | | | | | | | | | | | | | | | | Issue #27128: Add _PyObject_FastCall(), a new calling convention avoiding a temporary tuple to pass positional parameters in most cases, but create a temporary tuple if needed (ex: for the tp_call slot). The API is prepared to support keyword parameters, but the full implementation will come later (_PyFunction_FastCall() doesn't support keyword parameters yet). Add also: * _PyStack_AsTuple() helper function: convert a "stack" of parameters to a tuple. * _PyCFunction_FastCall(): fast call implementation for C functions * _PyFunction_FastCall(): fast call implementation for Python functions

* | Issue #23571: _Py_CheckFunctionResult() now gives the name of the functionVictor Stinner2015-03-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | which returned an invalid result (result+error or no result without error) in the exception message. Add also unit test to check that the exception contains the name of the function. Special case: the final _PyEval_EvalFrameEx() check doesn't mention the function since it didn't execute a single function but a whole frame.
* | Issue #23571: PyObject_Call(), PyCFunction_Call() and call_function() nowVictor Stinner2015-03-061-49/+52
| | | | | | | | | | | | | | | | | | | | | | raise a SystemError if a function returns a result and raises an exception. The SystemError is chained to the previous exception. Refactor also PyObject_Call() and PyCFunction_Call() to make them more readable. Remove some checks which became useless (duplicate checks). Change reviewed by Serhiy Storchaka.

* Issue #20530: Argument Clinic's signature format has been revised again.Larry Hastings2014-02-091-2/+2
| | | | | | | The new syntax is highly human readable while still preventing false positives. The syntax also extends Python syntax to denote "self" and positional-only parameters, allowing inspect.Signature objects to be totally accurate for all supported builtins in Python 3.4.
* Issue #20326: Argument Clinic now uses a simple, unique signature toLarry Hastings2014-01-281-6/+2
| | | | | | | | | | annotate text signatures in docstrings, resulting in fewer false positives. "self" parameters are also explicitly marked, allowing inspect.Signature() to authoritatively detect (and skip) said parameters. Issue #20326: Argument Clinic now generates separate checksums for the input and output sections of the block, allowing external tools to verify that the input has not changed (and thus the output is not out-of-date).
* Issue #20189: Four additional builtin types (PyTypeObject,Larry Hastings2014-01-241-61/+6
| | | | | | PyMethodDescr_Type, _PyMethodWrapper_Type, and PyWrapperDescr_Type) have been modified to provide introspection information for builtins. Also: many additional Lib, test suite, and Argument Clinic fixes.
* Silence expression result unused warnings with clang.Christian Heimes2013-12-041-1/+1

* Make identifiers str (not str8) objects throughout.Martin v. Löwis2007-06-101-2/+2
| | | | | | | | | | | | | | | | | | | This affects the parser, various object implementations, and all places that put identifiers into C string literals. In testing, a number of crashes occurred as code would fail when the recursion limit was reached (such as the Unicode interning dictionary having key/value pairs where key is not value). To solve these, I added an overflowed flag, which allows for 50 more recursions after the limit was reached and the exception was raised, and a recursion_critical flag, which indicates that recursion absolutely must be allowed, i.e. that a certain call must not cause a stack overflow exception. There are still some places where both str and str8 are accepted as identifiers; these should eventually be removed.
* Add functions PyUnicode_Append() and PyUnicode_AppendAndDel() that mirrorWalter Dörwald2007-05-181-2/+2
| | | | | | | | | | | | | | | PyString_Concat() and PyString_ConcatAndDel() (the name PyUnicode_Concat() was already taken). Change PyObject_Repr() to always return a unicode object. Update all repr implementations to return unicode objects. Add a function PyObject_ReprStr8() that calls PyObject_Repr() and converts the result to an 8bit string. Use PyObject_ReprStr8() where using PyObject_Repr() can't be done straightforward.

* Restructure comparison dramatically. There is no longer a defaultGuido van Rossum2006-08-241-11/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | *ordering* between objects; there is only a default equality test (defined by an object being equal to itself only). Read the comment in object.c. The current implementation never uses a three-way comparison to compute a rich comparison, but it does use a rich comparison to compute a three-way comparison. I'm not quite done ripping out all the calls to PyObject_Compare/Cmp, or replacing tp_compare implementations with tp_richcompare implementations; but much of that has happened (to make most unit tests pass). The following tests still fail, because I need help deciding or understanding: test_codeop -- depends on comparing code objects test_datetime -- need Tim Peters' opinion test_marshal -- depends on comparing code objects test_mutants -- need help understanding it The problem with test_codeop and test_marshal is this: these tests compare two different code objects and expect them to be equal. Is that still a feature we'd like to support? I've temporarily removed the comparison and hash code from code objects, so they use the default (equality by pointer only) comparison. For the other two tests, run them to see for yourself. (There may be more failing test with "-u all".) A general problem with getting lots of these tests to pass is the reality that for object types that have a natural total ordering, implementing __cmp__ is much more convenient than implementing __eq__, __ne__, __lt__, and so on. Should we go back to allowing __cmp__ to provide a total ordering? Should we provide some other way to implement rich comparison with a single method override? Alex proposed a __key__() method; I've considered a __richcmp__() method. Or perhaps __cmp__() just shouldn't be killed off...
