* [3.5] Backport bpo-30876 (GH-2639), bpo-18018 and bpo-26367. (#2677)Serhiy Storchaka2017-07-232-2/+7
| | | | | | | | | | | | | | | | * bpo-30876: Relative import from unloaded package now reimports the package instead of failing with SystemError. Relative import from non-package now fails with ImportError rather than SystemError. (cherry picked from commit 8a9cd20edca7d01b68292036029ae3735ce65edd) * bpo-18018: Import raises ImportError instead of SystemError if a relative import is attempted without a known parent package. * bpo-26367: importlib.__init__() raises ImportError like builtins.__import__() when ``level`` is specified but without an accompanying package specified.
* [3.5] bpo-29514: Check magic number for bugfix releases (#2158)Nick Coghlan2017-06-131-0/+44
| | | | | | | | | | | | 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. This ensures that pre-merge CI will automatically pick up on magic number changes in maintenance releases (and explain why those are problematic), rather than relying on all core developers to be aware of the implications of such changes.
* [3.5] bpo-29537: Tolerate legacy invalid bytecode (#169)Nick Coghlan2017-03-081-0/+104
| | | | | | | | | | | | | | | | | | bpo-27286 fixed a problem where BUILD_MAP_UNPACK_WITH_CALL could be emitted with an incorrect oparg value, causing the eval loop to access the wrong stack entry when attempting to read the function name. The associated magic number change caused significant problems when attempting to upgrade to 3.5.3 for anyone that relies on pre-cached bytecode remaining valid across maintenance releases. This patch restores the ability to import legacy bytecode generated by 3.5.0, 3.5.1 or 3.5.2, and modifies the eval loop to avoid any harmful consequences from the potentially malformed legacy bytecode. Original import patch by Petr Viktorin, eval loop patch by Serhiy Storchaka, and tests and integration by Nick Coghlan.

| | | | | | | | 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``. Patch by Xiang Zhang.

* Issue #26186: Remove an invalid type check inBrett Cannon2016-02-211-0/+1
| | | | | | | | | | | 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.
* Issue #26367: Have importlib.__init__() raise RuntimeError whenBrett Cannon2016-02-201-0/+5
| | | | | | | 'level' is specified but no __package__. This brings the function inline with builtins.__import__(). Thanks to Manuel Jacob for the patch.

* PEP 489: Multi-phase extension module initializationNick Coghlan2015-05-231-0/+167
| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | importlib.abc.Loader.exec_module() is also defined. Before this change, create_module() was optional **and** could return None to trigger default semantics. This change now reduces the options for choosing default semantics to one and in the most backporting-friendly way (define create_module() to return None).
