* bpo-39336: Allow packages to not let their child modules be set on them (#18006)Dino Viehland2020-01-221-1/+6
| | | | | * bpo-39336: Allow setattr to fail on modules which aren't assignable When attaching a child module to a package if the object in sys.modules raises an AttributeError (e.g. because it is immutable) it causes the whole import to fail. This now allows immutable packages to exist and an ImportWarning is reported and the AttributeError exception is ignored.

* bpo-37444: Update differing exception between builtins and importlib (GH-14869)Ngalim Siregar2019-08-021-1/+1
| | | | | | | | | | Imports now raise `TypeError` instead of `ValueError` for relative import failures. This makes things consistent between `builtins.__import__` and `importlib.__import__` as well as using a more natural import for the failure. https://bugs.python.org/issue37444 Automerge-Triggered-By: @brettcannon

* bpo-35321: Set the spec origin to frozen in frozen modules (#11732)Nina Zakharenko2019-02-041-2/+4
| | | | | | | | | | * bpo-35321: Set the spec origin to frozen in frozen modules This fix correctly sets the spec origin to "frozen" for the _frozen_importlib module. Note that the origin was already correctly set in _frozen_importlib_external. * 📜🤖 Added by blurb_it.
* bpo-33331: Clean modules in the reversed order in PyImport_Cleanup(). (GH-6565)Serhiy Storchaka2018-10-291-56/+62
| | | | | | Modules imported last are now cleared first at interpreter shutdown. A newly imported module is moved to the end of sys.modules, behind modules on which it depends.

* bpo-32303 - Consistency fixes for namespace loaders (#5481)Barry Warsaw2018-02-021-0/+12
| | | | | | | * Make sure ``__spec__.loader`` matches ``__loader__`` for namespace packages. * Make sure ``__spec__.origin` matches ``__file__`` for namespace packages. https://bugs.python.org/issue32303 https://bugs.python.org/issue32305
* bpo-21720: Restore the Python 2.7 logic in handling a fromlist. (#4118)Serhiy Storchaka2017-10-261-7/+13
| | | | | | BytesWarning no longer emitted when the fromlist argument of __import__() or the __all__ attribute of the module contain bytes instances.
* bpo-31642: Restore blocking "from" import by setting None in sys.modules. ↵Serhiy Storchaka2017-10-081-1/+2

| | | | | | * Trivial cleanups following bpo-31370 * Also cleanup the "importlib._bootstrap_external" module
* bpo-31070: Fix a race condition in importlib _get_module_lock(). (#3033)Serhiy Storchaka2017-08-091-2/+12

* bpo-30891: Fix again importlib _find_and_load() (#2665)Victor Stinner2017-07-211-5/+5
| | | | | | | | | Use sys.modules.get() in the "with _ModuleLockManager(name):" block to protect the dictionary key with the module lock and use an atomic get to prevent race condition. Remove also _bootstrap._POPULATE since it was unused (_bootstrap_external now has its own _POPULATE object), add a new _SENTINEL object instead.
* bpo-30876: Relative import from unloaded package now reimports the package ↵Serhiy Storchaka2017-07-121-4/+0
| | | | | | | | | (#2639) instead of failing with SystemError. Relative import from non-package now fails with ImportError rather than SystemError.
* bpo-30891: Fix importlib _find_and_load() race condition (#2646)Victor Stinner2017-07-101-28/+30
| | | | | | * Rewrite importlib _get_module_lock(): it is now responsible to hold the imp lock directly. * _find_and_load() now holds the module lock to check if name is in sys.modules to prevent a race condition
* bpo-30814: Fixed a race condition when import a submodule from a package. ↵Serhiy Storchaka2017-07-061-14/+14

* bpo-22257: Small changes for PEP 432. (#1728)Eric Snow2017-05-221-1/+4
| | | PEP 432 specifies a number of large changes to interpreter startup code, including exposing a cleaner C-API. The major changes depend on a number of smaller changes. This patch includes all those smaller changes.

| | | | | | | | | | | | Issue #26637: The importlib module now emits an ImportError rather than a TypeError if __import__() is tried during the Python shutdown process but sys.path is already cleared (set to None).

| | | | | | | | | | | | | | 'level' is specified but no __package__. This brings the function inline with builtins.__import__(). Thanks to Manuel Jacob for the patch.
* | Issue #25791: Warn when __package__ != __spec__.parent.Brett Cannon2016-01-221-3/+9
| | | | | | | | | | | | | | | | | | 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.

* PEP 489: Multi-phase extension module initializationNick Coghlan2015-05-231-10/+13
| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | The concept of .pyo files no longer exists. Now .pyc files have an optional `opt-` tag which specifies if any extra optimizations beyond the peepholer were applied.
* Issue #23014: Make importlib.abc.Loader.create_module() required whenBrett Cannon2015-01-091-0/+14
| | | | | | | | | 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).
