[2.7] bpo-35441: Remove dead and buggy code related to PyList_SetItem(). (GH-11033) (GH-11234)

2018-12-19T15:11:02Z

In _localemodule.c and selectmodule.c, remove dead code that would
cause double decrefs if run.

In addition, replace PyList_SetItem() with PyList_SET_ITEM() in cases
where a new list is populated and there is no possibility of an error.

In addition, check if the list changed size in the loop in array_array_fromlist().

bpo-33015: Use malloc() in PyThread_start_new_thread() (GH-10829)

2018-11-30T17:08:02Z

The pthread implementation of PyThread_start_new_thread() now uses
malloc/free rather than PyMem_Malloc/PyMem_Free, since the latters
are not thread-safe.

[2.7] bpo-35133: Fix mistakes when concatenate string literals on different lines. (GH-10284) (GH-10335) (GH-10336)

2018-11-05T16:16:26Z

Two kind of mistakes:

1. Missed space. After concatenating there is no space between words.

2. Missed comma. Causes unintentional concatenating in a list of strings.

bpo-25083: Python can sometimes create incorrect .pyc files (GH-8449)

2018-09-10T18:46:14Z

Python 2 never checked for I/O error when reading .py files and
thus could mistake an I/O error for EOF and create incorrect .pyc
files.
This adds an check for this and aborts on an error.
