[3.8] bpo-37409: fix relative import with no parent (GH-14956) (GH-15913)

2019-09-11T12:50:14+00:00

Relative imports use resolve_name to get the absolute target name,
which first seeks the current module's absolute package name from the globals:
If __package__ (and __spec__.parent) are missing then
import uses __name__, truncating the last segment if
the module is a submodule rather than a package __init__.py
(which it guesses from whether __path__ is defined).

The __name__ attempt should fail if there is no parent package (top level modules),
if __name__ is '__main__' (-m entry points), or both (scripts).
That is, if both __name__ has no subcomponents and the module does not seem
to be a package __init__ module then import should fail..

2018-11-05T14:52:58+00:00

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.

rename _imp initialization function to follow conventions (#5432)

2018-01-29T19:33:57+00:00

When the C imp module became _imp in 6f44d66bc491bad5b8d897a68da68e009e27829d, the initialization function should have been renamed from PyInit_imp to PyInit__imp.

fix up signedness in PyImport_ExtendInittab (#4831)

2017-12-16T07:42:33+00:00

As a result of 92a3c6f493ad411e4cf0acdf305ef4876aa90669, the compiler complains:

Python/import.c:2311:21: warning: comparison of integers of different signs: 'long' and 'unsigned long' [-Wsign-compare]
    if ((i + n + 1) <= PY_SSIZE_T_MAX / sizeof(struct _inittab)) {
         ~~~~~~~~~  ^  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This overflow is extremely unlikely to happen, but let's avoid undefined
behavior anyway.
