| | | | | | | | Emit a deprecation warning if the numeric literal is immediately followed by one of keywords: and, else, for, if, in, is, or. Raise a syntax error with more informative message if it is immediately followed by other keyword or identifier. Automerge-Triggered-By: GH:pablogsal

* bpo-39573: Py_TYPE becomes a static inline function (GH-26493)Victor Stinner2021-06-031-0/+28
| | | | | Convert the Py_TYPE() and Py_SIZE() macros to static inline functions. The Py_SET_TYPE() and Py_SET_SIZE() functions must now be used to set an object type and size.

| | | | | The PyType_Ready() function now raises an error if a type is defined with the Py_TPFLAGS_HAVE_GC flag set but has no traverse function (PyTypeObject.tp_traverse).

* bpo-43795: Remove Py_FrozenMain from the Limited API & Stable ABI (GH-26241)Petr Viktorin2021-05-251-0/+4
| | | | | | | | | | | Py_FrozenMain was added to the Limited C API in [bpo-42591]() (3.10.0a4); but to fix that issue it would be enough to add it to the regular C API. The function is undocumented, tests were added very recently ([bpo-44131]()), and most importantly, it is not present in all builds of Python, as the linker sometimes omits it as unused. It should be added back when these issues are fixed. Note that this does not affect Python's regular C API.
* bpo-38908: [docs] Add changes to 3.10 whatsnew and fix some minor ↵Ken Jin2021-05-241-0/+8
| | | | | inaccuracies in news (GH-26096) The fix only applies to ``isinstance``. ``issubclass`` isn't affected (because it was always working to begin with). So I also fixed the news to reflect that.

| | | | | | | | | | | | | | | | | Deprecate the following functions to configure the Python initialization: * PySys_AddWarnOption() * PySys_AddWarnOptionUnicode() * PySys_AddXOption() * PySys_HasWarnOptions() * Py_SetPath() * Py_SetProgramName() * Py_SetPythonHome() * Py_SetStandardStreamEncoding() * _Py_SetProgramFullPath() Use the new PyConfig API of the Python Initialization Configuration instead (PEP 587).

(GH-5012) C-style formatting with literal format containing only format codes %s, %r and %a (with optional width, precision and alignment) will be converted to an equivalent f-string expression. It can speed up formatting more than 2 times by eliminating runtime parsing of the format string and creating temporary tuple.

* bpo-43998: Default to TLS 1.2 and increase cipher suite security (GH-25778)Christian Heimes2021-05-011-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ssl module now has more secure default settings. Ciphers without forward secrecy or SHA-1 MAC are disabled by default. Security level 2 prohibits weak RSA, DH, and ECC keys with less than 112 bits of security. :class:`~ssl.SSLContext` defaults to minimum protocol version TLS 1.2.

* bpo-43916: Add Py_TPFLAGS_DISALLOW_INSTANTIATION type flag (GH-25721)Victor Stinner2021-04-301-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new Py_TPFLAGS_DISALLOW_INSTANTIATION type flag to disallow creating type instances: set tp_new to NULL and don't create the "__new__" key in the type dictionary. The flag is set automatically on static types if tp_base is NULL or &PyBaseObject_Type and tp_new is NULL. Use the flag on the following types: * _curses.ncurses_version type * _curses_panel.panel * _tkinter.Tcl_Obj * _tkinter.tkapp * _tkinter.tktimertoken * _xxsubinterpretersmodule.ChannelID * sys.flags type * sys.getwindowsversion() type * sys.version_info type Update MyStr example in the C API documentation to use Py_TPFLAGS_DISALLOW_INSTANTIATION. Add _PyStructSequence_InitType() function to create a structseq type with the Py_TPFLAGS_DISALLOW_INSTANTIATION flag set. type_new() calls _PyType_CheckConsistency() at exit.
* bpo-43774: Enhance debug build documentation (GH-25712)Victor Stinner2021-04-291-2/+2
| | | | | * Add also references to --with-trace-refs option. * Move _ob_next and _ob_prev at the end, since they don't exist by default and are related to debug.

| | | | | | | | | Faster bz2/lzma/zlib via new output buffering. Also adds .readall() function to _compression.DecompressReader class to take best advantage of this in the consume-all-output at once scenario. Often a 5-20% speedup in common scenarios due to less data copying. Contributed by Ma Lin.
