* bpo-39791 native hooks for importlib.resources.files (GH-20576)Jason R. Coombs2020-06-075-115/+110
| | | | | | | | | | | | | | | | | | | | | | | | | * Provide native .files support on SourceFileLoader. * Add native importlib.resources.files() support to zipimporter. Remove fallback support. * make regen-all * πŸ“œπŸ€– Added by blurb_it. * Move 'files' into the ResourceReader so it can carry the relevant module name context. * Create 'importlib.readers' module and add FileReader to it. * Add zip reader and rely on it for a TraversableResources object on zipimporter. * Remove TraversableAdapter, no longer needed. * Update blurb. * Replace backslashes with forward slashes. * Incorporate changes from importlib_metadata 2.0, finalizing the interface for extension via get_resource_reader.

* bpo-40050: Fix importlib._bootstrap_external (GH-19135)Victor Stinner2020-03-241-21/+13
| | | | | | Remove two unused imports: _thread and _weakref. Avoid creating a new winreg builtin module if it's already available in sys.modules. The winreg module is now stored as "winreg" rather than "_winreg".
* bpo-38691: importlib ignores PYTHONCASEOK if -E is used (GH-18627)idomic2020-03-091-2/+2
| | | | | The importlib module now ignores the PYTHONCASEOK environment variable when the -E or -I command line options are being used.

* bpo-39320: Handle unpacking of **values in compiler (GH-18141)Mark Shannon2020-01-271-1/+2
| | | | | | | | | | | | | * Add DICT_UPDATE and DICT_MERGE bytecodes. Use them for ** unpacking. * Remove BUILD_MAP_UNPACK and BUILD_MAP_UNPACK_WITH_CALL, as they are now unused. * Update magic number for ** unpacking opcodes. * Update dis.rst to incorporate new bytecodes. * Add blurb entry.
* bpo-39320: Handle unpacking of *values in compiler (GH-17984)Mark Shannon2020-01-231-1/+3
| | | | | | | | * Add three new bytecodes: LIST_TO_TUPLE, LIST_EXTEND, SET_UPDATE. Use them to implement star unpacking expressions. * Remove four bytecodes BUILD_LIST_UNPACK, BUILD_TUPLE_UNPACK, BUILD_SET_UNPACK and BUILD_TUPLE_UNPACK_WITH_CALL opcodes as they are now unused. * Update magic number and dis.rst for new bytecodes.
* 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-39156: Break up COMPARE_OP into four logically distinct opcodes. (GH-17754)Mark Shannon2020-01-141-1/+2
| | | | | | | | Break up COMPARE_OP into four logically distinct opcodes: * COMPARE_OP for rich comparisons * IS_OP for 'is' and 'is not' tests * CONTAINS_OP for 'in' and 'is not' tests * JUMP_IF_NOT_EXC_MATCH for checking exceptions in 'try-except' statements.

As these variables are not used anyway, we can remove the binding to reduce the chances of creating reference cycles. See for example GH-13135

| | | | | | | | | | 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

| | | | | | | | | | | | | | | (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.
