* gh-76785: Rename _xxsubinterpreters to _interpreters (gh-117791)Eric Snow2024-04-241-1/+1
| | | See https://discuss.python.org/t/pep-734-multiple-interpreters-in-the-stdlib/41147/26.
* gh-117649: Raise ImportError for unsupported modules in free-threaded build ↵Sam Gross2024-04-111-0/+4
| | | | | | | | | | (#117651) The free-threaded build does not currently support the combination of single-phase init modules and non-isolated subinterpreters. Ensure that `check_multi_interp_extensions` is always `True` for subinterpreters in the free-threaded build so that importing these modules raises an `ImportError`.
* gh-76785: Consolidate Some Interpreter-related Testing Helpers (gh-117485)Eric Snow2024-04-021-2/+2
| | | This eliminates the duplication of functionally identical helpers in the _testinternalcapi and _xxsubinterpreters modules.

| | | | | | | | | | | The original name wasn't as clear as it could have been. This change includes the following: * rename the function * change the default value for "disable_check" to False * add clues to the docstring that folks should probably not use the function --------- Co-authored-by: Kirill Podoprigora <kirill.bast9@mail.ru>

| | | | | | Fix compilation of "break" and "continue" in the "finally" block when the corresponding "try" block contains "return" with a non-constant value.
* bpo-37444: Update differing exception between builtins and importlib (GH-14869)Ngalim Siregar2019-08-031-3/+3
| | | | | | | | | | 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-33499: Add PYTHONPYCACHEPREFIX env var for alt bytecode cache location. ↵Carl Meyer2018-06-161-11/+84
| | | | | | | | | | | | | | | (GH-6834) In some development setups it is inconvenient or impossible to write bytecode caches to the code tree, but the bytecode caches are still useful. The PYTHONPYCACHEPREFIX environment variable allows specifying an alternate location for cached bytecode files, within which a directory tree mirroring the code tree will be created. This cache tree is then used (for both reading and writing) instead of the local `__pycache__` subdirectory within each source directory. Exposed at runtime as sys.pycache_prefix (defaulting to None), and can be set from the CLI as "-X pycache_prefix=path". Patch by Carl Meyer.

* bpo-29514: Check magic number for bugfix release (#54)Eric Appelt2017-04-171-0/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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. BPO: 29514

* Issue #23014: Make importlib.abc.Loader.create_module() required whenBrett Cannon2015-01-091-3/+9
| | | | | | | | | 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).
* Issue #20383: Introduce importlib.util.module_from_spec().Brett Cannon2014-05-301-37/+115

| | | | | | | | | | | | | | | | | | | | | importlib.abc.Loader.init_module_attrs() and implement importlib.abc.InspectLoader.load_module(). The importlib.abc.Loader.init_module_attrs() method sets the various attributes on the module being loaded. It is done unconditionally to support reloading. Typically people used importlib.util.module_for_loader, but since that's a decorator there was no way to override it's actions, so init_module_attrs() came into existence to allow for overriding. This is also why module_for_loader is now pending deprecation (having its other use replaced by importlib.util.module_to_load). All of this allowed for importlib.abc.InspectLoader.load_module() to be implemented. At this point you can now implement a loader with nothing more than get_code() (which only requires get_source(); package support requires is_package()). Thanks to init_module_attrs() the implementation of load_module() is basically a context manager containing 2 methods calls, a call to exec(), and a return statement.

* Issue #15168: Move importlb.test to test.test_importlib.Brett Cannon2012-07-201-0/+208
This should make the Linux distros happy as it is now easier to leave importlib's tests out of their base Python distribution.
