bpo-32674: Improve the docstring for import (GH-5339) (GH-5488)

2018-02-02T04:51:36+00:00

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 (GH-5222)

2018-01-25T08:49:40+00:00

Add two new private APIs: _PyObject_LookupAttr() and _PyObject_LookupAttrId()

bpo-9566: Fix size_t=>int downcast warnings (#5230)

2018-01-18T10:15:25+00:00

* 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)

2018-01-16T11:52:41+00:00

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)

2017-12-16T03:54:22+00:00

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 arguments. (#4746)

bpo-32226: Implementation of PEP 560 (core components) (#4732)

2017-12-14T22:32:56+00:00

This part of the PEP implementation adds support for
__mro_entries__ and __class_getitem__ by updating
__build_class__ and PyObject_GetItem.
