* 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

* bpo-38237: Make pow's arguments have more descriptive names and be keyword ↵Ammar Askar2019-09-211-8/+8
| | | | | | | | | | | | 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.

* 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.

| | | Adds sys.audit, sys.addaudithook, io.open_code, and associated C APIs.
* bpo-36791: Safer detection of integer overflow in sum(). (GH-13080)Serhiy Storchaka2019-05-051-3/+5
|
* 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

* bpo-35177: Add dependencies between header files (GH-10361)Victor Stinner2018-11-111-9/+2
| | | | | | | | | | | | | | * ast.h now includes Python-ast.h and node.h * parsetok.h now includes node.h and grammar.h * symtable.h now includes Python-ast.h * Modify asdl_c.py to enhance Python-ast.h: * Add #ifndef/#define Py_PYTHON_AST_H to be able to include the header twice * Add "extern { ... }" for C++ * Undefine "Yield" macro conflicting with winbase.h * Remove "#undef Yield" from C files, it's now done in Python-ast.h * Remove now useless includes in C files
* bpo-35081: Add pycore_ prefix to internal header files (GH-10263)Victor Stinner2018-10-311-1/+1
| | | | | | | | | | | | | | | | | | | | * Rename Include/internal/ header files: * pyatomic.h -> pycore_atomic.h * ceval.h -> pycore_ceval.h * condvar.h -> pycore_condvar.h * context.h -> pycore_context.h * pygetopt.h -> pycore_getopt.h * gil.h -> pycore_gil.h * hamt.h -> pycore_hamt.h * hash.h -> pycore_hash.h * mem.h -> pycore_mem.h * pystate.h -> pycore_state.h * warnings.h -> pycore_warnings.h * PCbuild project, Makefile.pre.in, Modules/Setup: add the Include/internal/ directory to the search paths of header files. * Update includes.

* bpo-34637: Make the *start* argument for *sum()* visible as a keyword ↵Raymond Hettinger2018-09-121-2/+2
| | | | argument. (GH-9208)
* bpo-34523: Use _PyCoreConfig instead of globals (GH-9005)Victor Stinner2018-08-291-1/+4
| | | | | Use the core configuration of the interpreter, rather than using global configuration variables. For example, replace Py_QuietFlag with core_config->quiet.
* closes bpo-34474: Python/bltinmodule.c: Add missing NULL check in ↵Alexey Izbyshev2018-08-241-0/+5
| | | | | builtin_sum_impl() (GH-8872) Reported by Svace static analyzer.
* bpo-34170: Add Python/coreconfig.c for _PyCoreConfig (GH-8607)Victor Stinner2018-08-011-23/+0
| | | | | | | * Add Include/coreconfig.h * Move config_*() and _PyCoreConfig_*() functions from Modules/main.c to a new Python/coreconfig.c file. * Inline _Py_ReadHashSeed() into config_init_hash_seed() * Move global configuration variables to coreconfig.c

* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-3/+3
| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.
* bpo-32674: Improve the docstring for __import__ (GH-5339)oldk2018-02-021-3/+3
| | | | | Clarify that the level argument is used to determine whether to perform absolute or relative imports: 0 is absolute, while a positive number is the number of parent directories to search relative to the current module.
* bpo-32571: Avoid raising unneeded AttributeError and silencing it in C code ↵Serhiy Storchaka2018-01-251-24/+13
| | | | | (GH-5222) Add two new private APIs: _PyObject_LookupAttr() and _PyObject_LookupAttrId()
* bpo-9566: Fix size_t=>int downcast warnings (#5230)Victor Stinner2018-01-181-2/+2
| | | | * Use wider types (int => Py_ssize_t) to avoid integer overflows. * Fix gc.get_freeze_count(): use Py_ssize_t type rather than int, since gc_list_size() returns a Py_ssize_t.
* bpo-32544: Speed up hasattr() and getattr() (GH-5173)INADA Naoki2018-01-161-10/+11
| | | | | AttributeError was raised always when attribute is not found. This commit skip raising AttributeError when `tp_getattro` is `PyObject_GenericGetAttr`. It makes hasattr() and getattr() about 4x faster when attribute is not found.
* bpo-29240, bpo-32030: Py_Main() re-reads config if encoding changes (#4899)Victor Stinner2017-12-161-3/+4
| | | | | | | | | | | | | | | | | | bpo-29240, bpo-32030: If the encoding change (C locale coerced or UTF-8 Mode changed), Py_Main() now reads again the configuration with the new encoding. Changes: * Add _Py_UnixMain() called by main(). * Rename pymain_free_pymain() to pymain_clear_pymain(), it can now be called multipled times. * Rename pymain_parse_cmdline_envvars() to pymain_read_conf(). * Py_Main() now clears orig_argc and orig_argv at exit. * Remove argv_copy2, Py_Main() doesn't modify argv anymore. There is no need anymore to get two copies of the wchar_t** argv. * _PyCoreConfig: add coerce_c_locale and coerce_c_locale_warn. * Py_UTF8Mode is now initialized to -1. * Locale coercion (PEP 538) now respects -I and -E options.
* bpo-32240: Add the const qualifier to declarations of PyObject* array ↵Serhiy Storchaka2017-12-151-6/+6
| | | | arguments. (#4746)
* bpo-32226: Implementation of PEP 560 (core components) (#4732)Ivan Levkivskyi2017-12-141-3/+92
| | | | | This part of the PEP implementation adds support for __mro_entries__ and __class_getitem__ by updating __build_class__ and PyObject_GetItem.
* bpo-29240: PEP 540: Add a new UTF-8 Mode (#855)Victor Stinner2017-12-131-0/+3
| | | | | | | | | | | | | | | | | | | | | | * Add -X utf8 command line option, PYTHONUTF8 environment variable and a new sys.flags.utf8_mode flag. * If the LC_CTYPE locale is "C" at startup: enable automatically the UTF-8 mode. * Add _winapi.GetACP(). encodings._alias_mbcs() now calls _winapi.GetACP() to get the ANSI code page * locale.getpreferredencoding() now returns 'UTF-8' in the UTF-8 mode. As a side effect, open() now uses the UTF-8 encoding by default in this mode. * Py_DecodeLocale() and Py_EncodeLocale() now use the UTF-8 encoding in the UTF-8 Mode. * Update subprocess._args_from_interpreter_flags() to handle -X utf8 * Skip some tests relying on the current locale if the UTF-8 mode is enabled. * Add test_utf8mode.py. * _Py_DecodeUTF8_surrogateescape() gets a new optional parameter to return also the length (number of wide characters). * pymain_get_global_config() and pymain_set_global_config() now always copy flag values, rather than only copying if the new value is greater than the old value.
* bpo-30950: Convert round() to Argument Clinic. (#2740)Serhiy Storchaka2017-11-151-19/+16
