Garvit Khatri 94987826e8 bpo-29851: Have importlib.reload() raise ImportError if the module's spec is not found (GH-972) 2017-05-24 15:19:50 -07:00
Serhiy Storchaka 3cc8259b71 bpo-30158: Fix deprecation warnings in test_importlib introduced by bpo-29576. (#1285) 2017-04-29 07:06:49 +03:00
Eric Appelt d6d344d833 bpo-29514: Check magic number for bugfix release (#54)
* bpo-29514: Check magic number for micro release

Add a dict importlib.util.EXPECTED_MAGIC_NUMBERS which
details the initial and expected pyc magic number for
each minor release. This gives a mechanism for users to
check if the magic number has changed within a release and
for a test to ensure procedure is followed if a change is
necessary.

Add a test to check the current MAGIC_NUMBER against the
expected number for the release if the current release is
at candidate or final level. On test failure, describe to
the developer the procedure for changing the magic number.

* Simplify magic number release test

Simplify the magic number release test by removing
EXPECTED_MAGIC_NUMBERS table and making the expected
magic number self-contained within the test.

BPO: 29514

* Improve magic number test execution and message

Improve the execution of the magic number test by
using skipUnless for alpha and beta releases, and
directly inheriting from unittest.TestCase rather than
using the machinery for the other tests. Also improve
the error message to explain the reason for caution in
changing the magic number.

Nick Coghlan 8682f578c1 Issue #27782: Fix m_methods handling in multiphase init
Multi-phase extension module import now correctly allows the
``m_methods`` field to be used to add module level functions
to instances of non-module types returned from ``Py_create_mod``.

Brett Cannon a47a7a5bf8 Issue #27083: Respect the PYTHONCASEOK environment variable under
Windows.

Originally only b'PYTHONCASEOK' was being checked for in os.environ,
but that won't work under Windows where all environment variables are
strings (on OS X they are bytes).

Thanks to Eryk Sun for the bug report.

Brett Cannon 696c35e86b Issue #26186: Remove the restriction that built-in and extension
modules  can't be lazily loaded.

Thanks to Python 3.6 allowing for types.ModuleType to have its
__class__ mutated, the restriction can be lifted by calling
create_module() on the wrapped loader.

Brett Cannon 558823a0cf Issue #26186: Remove an invalid type check in
importlib.util.LazyLoader.

The class was checking its argument as to whether its implementation
of create_module() came directly from importlib.abc.Loader. The
problem is that the classes coming from imoprtlib.machinery do not
directly inherit from the ABC as they come from _frozen_importlib.
Because the documentation has always said that create_module() was
ignored, the check has simply been removed.

Brett Cannon 9fa812668f Issue #18018: Raise an ImportError if a relative import is attempted

Brett Cannon 849113af6b Issue #25791: Warn when __package__ != __spec__.parent.
In a previous change, __spec__.parent was prioritized over
__package__. That is a backwards-compatibility break, but we do
eventually want __spec__ to be the ground truth for module details. So
this change reverts the change in semantics and instead raises an
ImportWarning when __package__ != __spec__.parent to give people time
to adjust to using spec objects.

Brett Cannon 63b8505281 Issue #25791: Raise an ImportWarning when __spec__ or __package__ are
not defined for a relative import.

This is the start of work to try and clean up import semantics to rely
more on a module's spec than on the myriad attributes that get set on
a module. Thanks to Rose Ames for the patch.

Nick Coghlan d5cacbb1d9 PEP 489: Multi-phase extension module initialization
Known limitations of the current implementation:

- documentation changes are incomplete
- there's a reference leak I haven't tracked down yet

The leak is most visible by running:

  ./python -m test -R3:3 test_importlib

However, you can also see it by running:

  ./python -X showrefcount

Importing the array or _testmultiphase modules, and
then deleting them from both sys.modules and the local
namespace shows significant increases in the total
number of active references each cycle. By contrast,
with _testcapi (which continues to use single-phase
initialisation) the global refcounts stabilise after
a couple of cycles.
