bpo-43914: Highlight invalid ranges in SyntaxErrors (#25525)

2021-04-23T13:27:05Z

To improve the user experience understanding what part of the error messages associated with SyntaxErrors is wrong, we can highlight the whole error range and not only place the caret at the first character. In this way:

>>> foo(x, z for z in range(10), t, w)
  File "", line 1
    foo(x, z for z in range(10), t, w)
           ^
SyntaxError: Generator expression must be parenthesized

becomes

>>> foo(x, z for z in range(10), t, w)
  File "", line 1
    foo(x, z for z in range(10), t, w)
           ^^^^^^^^^^^^^^^^^^^^
SyntaxError: Generator expression must be parenthesized

bpo-43687: Py_Initialize() creates singletons earlier (GH-25147)

2021-04-02T13:28:13Z

Reorganize pycore_interp_init() to initialize singletons before the
the first PyType_Ready() call. Fix an issue when Python is configured
using --without-doc-strings.

bpo-32381: Rewrite PyErr_ProgramText() (GH-23700)

2020-12-08T22:51:26Z

PyErr_ProgramText() now calls PyErr_ProgramTextObject().

bpo-42599: Remove useless PyModule_GetWarningsModule() (GH-23691)

2020-12-08T14:42:42Z

Removed PyModule_GetWarningsModule() which is useless due to 
the _warnings module was converted to a builtin module in 2.6.

bpo-42500: Fix recursion in or after except (GH-23568)

2020-12-02T13:30:55Z

* Use counter, rather boolean state when handling soft overflows.

bpo-42152: Use PyDict_Contains and PyDict_SetDefault if appropriate. (GH-22986)

2020-10-26T10:47:57Z

If PyDict_GetItemWithError is only used to check whether the key is in dict,
it is better to use PyDict_Contains instead.

And if it is used in combination with PyDict_SetItem, PyDict_SetDefault can
replace the combination.
