The ``sys.path[0]`` initialization change for bpo-29139 caused a regression
|
|
by revealing an inconsistency in how sys.path is initialized when executing
|
|
``__main__`` from a zipfile, directory, or other import location. This is
|
|
considered a potential security issue, as it may lead to privileged
|
|
processes unexpectedly loading code from user controlled directories in
|
|
situations where that was not previously the case.
|
|
The interpreter now consistently avoids ever adding the import location's
|
|
parent directory to ``sys.path``, and ensures no other ``sys.path`` entries
|
|
are inadvertently modified when inserting the import location named on the
|
|
command line. (Originally reported as bpo-29723 against Python 3.6rc1, but
|
|
it was missed at the time that the then upcoming Python 3.5.4 release would
|
|
also be affected)
