* bpo-40334: Support type comments (GH-19780)Guido van Rossum2020-04-301-5/+1
| | | | | | | | | | This implements full support for # type: <type> comments, # type: ignore <stuff> comments, and the func_type parsing mode for ast.parse() and compile(). Closes https://github.com/we-like-parsers/cpython/issues/95. (For now, you need to use the master branch of mypy, since another issue unique to 3.9 had to be fixed there, and there's no mypy release yet.) The only thing missing is `feature_version=N`, which is being tracked in https://github.com/we-like-parsers/cpython/issues/124.
* bpo-40334: Use old compiler when compile mode is func_type (GH-19692)Guido van Rossum2020-04-231-1/+1
| | | | | This is invoked by mypy, using ast.parse(source, "<func_type>", "func_type"). Since the new grammar doesn't yet support the func_type_input start symbol we must use the old compiler in this case to prevent a crash. https://bugs.python.org/issue40334
* bpo-40334: Rename PyConfig.use_peg to _use_peg_parser (GH-19670)Victor Stinner2020-04-231-3/+3
| | | | | | | | | | | * Rename PyConfig.use_peg to _use_peg_parser * Document PyConfig._use_peg_parser and mark it a deprecated * Mark -X oldparser option and PYTHONOLDPARSER env var as deprecated in the documentation. * Add use_old_parser() and skip_if_new_parser() to test.support * Remove sys.flags.use_peg: use_old_parser() uses _testinternalcapi.get_configs() instead. * Enhance test_embed tests * subprocess._args_from_interpreter_flags() copies -X oldparser
* bpo-40334: PEP 617 implementation: New PEG parser for CPython (GH-19503)Pablo Galindo2020-04-221-0/+5

* bpo-39562: Prevent collision of future and compiler flags (GH-19230)Batuhan Taşkaya2020-04-221-1/+1
| | | | | | The constant values of future flags in the __future__ module is updated in order to prevent collision with compiler flags. Previously PyCF_ALLOW_TOP_LEVEL_AWAIT was clashing with CO_FUTURE_DIVISION.

| | | | | | | | Don't access PyInterpreterState.config member directly anymore, but use new functions: * _PyInterpreterState_GetConfig() * _PyInterpreterState_SetConfig() * _Py_GetConfig()
* bpo-39245: Switch to public API for Vectorcall (GH-18460)Petr Viktorin2020-02-111-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The bulk of this patch was generated automatically with: for name in \ PyObject_Vectorcall \ Py_TPFLAGS_HAVE_VECTORCALL \ PyObject_VectorcallMethod \ PyVectorcall_Function \ PyObject_CallOneArg \ PyObject_CallMethodNoArgs \ PyObject_CallMethodOneArg \ ; do echo $name git grep -lwz _$name | xargs -0 sed -i "s/\b_$name\b/$name/g" done old=_PyObject_FastCallDict new=PyObject_VectorcallDict git grep -lwz $old | xargs -0 sed -i "s/\b$old\b/$new/g" and then cleaned up: - Revert changes to in docs & news - Revert changes to backcompat defines in headers - Nudge misaligned comments
* bpo-39573: Use Py_TYPE() macro in Python and Include directories (GH-18391)Victor Stinner2020-02-071-8/+8
| | | Replace direct access to PyObject.ob_type with Py_TYPE().
* bpo-39542: Declare _Py_AddToAllObjects() in pycore_object.h (GH-18368)Victor Stinner2020-02-051-1/+2
| | | | | | _Py_AddToAllObjects() is used in bltinmodule.c and typeobject.c when Py_TRACE_REFS is defined. Fix Py_TRACE_REFS build.
* Update sum comment. (#18240)Brandt Bucher2020-02-011-1/+5
|
* bpo-39200: Correct the error message for min/max builtin function (GH-17814)Dong-hee Na2020-01-101-2/+7
| | | | Correct the error message when calling the min() or max() with no arguments.
* bpo-38835: Don't use PyFPE_START_PROTECT and PyFPE_END_PROTECT (GH-17231)Victor Stinner2019-11-201-4/+0
| | | | | The PyFPE_START_PROTECT() and PyFPE_END_PROTECT() macros are empty: they have been doing nothing for the last year (since commit 735ae8d139a673b30b321dc10acfd3d14f0d633b), so stop using them.
* bpo-38644: Add _PyObject_Call() (GH-17089)Victor Stinner2019-11-141-7/+8
| | | | | | | | | | * Add pycore_call.h internal header file. * Add _PyObject_Call(): PyObject_Call() with tstate * Add _PyObject_CallNoArgTstate(): _PyObject_CallNoArg() with tstate * Add _PyObject_FastCallDictTstate(): _PyObject_FastCallDict() with tstate * _PyObject_Call_Prepend() now takes tstate * Replace _PyObject_FastCall() calls with _PyObject_VectorcallTstate() calls

| | | | | | | | | | | | passable (GH-16302) Edit: `math.pow` changes removed on Mark's request. https://bugs.python.org/issue38237 Automerge-Triggered-By: @rhettinger
* bpo-37206: Unrepresentable default values no longer represented as None. ↵Serhiy Storchaka2019-09-141-3/+3
| | | | | | | (GH-13933) In ArgumentClinic, value "NULL" should now be used only for unrepresentable default values (like in the optional third parameter of getattr). "None" should be used if None is accepted as argument and passing None has the same effect as not passing the argument at all.

| | | | | | | | * Optimize sum() for bools. * Fix sum([], False). * Add a NEWS entry.

* bpo-37253: Add _PyCompilerFlags_INIT macro (GH-14018)Victor Stinner2019-06-131-6/+3
| | | | | Add a new _PyCompilerFlags_INIT macro to initialize PyCompilerFlags variables, rather than initializing cf_flags and cf_feature_version explicitly in each variable.
* bpo-35766: compile(): rename feature_version parameter (GH-13994)Victor Stinner2019-06-121-2/+3
| | | | | | Rename compile() feature_version parameter to _feature_version and convert it to a keyword-only parameter. Update also test_type_comments to pass feature_version as a tuple.

* bpo-35975: Support parsing earlier minor versions of Python 3 (GH-12086)Guido van Rossum2019-03-071-2/+9
| | | | | | | This adds a `feature_version` flag to `ast.parse()` (documented) and `compile()` (hidden) that allow tweaking the parser to support older versions of the grammar. In particular if `feature_version` is 5 or 6, the hacks for the `async` and `await` keyword from PEP 492 are reinstated. (For 7 or higher, these are unconditionally treated as keywords, but they are still special tokens rather than `NAME` tokens that the parser driver recognizes.) https://bugs.python.org/issue35975
