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.	11 years ago

Brett Cannon	f299abdafa	Issue #23731 : Implement PEP 488. 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.	11 years ago

Brett Cannon	02d8454002	Issue #23014 : Make importlib.abc.Loader.create_module() required when 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).	11 years ago

Brett Cannon	2a17bde930	Issue #20383 : Introduce importlib.util.module_from_spec(). Along the way, dismantle importlib._bootstrap._SpecMethods as it was no longer relevant and constructing the new function required partially dismantling the class anyway.	12 years ago

Eric Snow	e4314e05d5	Issue 19713: Remove PEP 451-related code that should have been factored out. This code was an artifact of issuing a DeprecationWarning for the lack of loader.exec_module(). However, we have deferred such warnings to later Python versions.	12 years ago

Eric Snow	61e851baca	Remove some dead code in importlib, introduced with the PEP 451 patch. Early in the PEP 451 implementation some of the importlib loaders had their own _get_spec() methods to simplify accommodating them. However, later implementations removed the need. They simply failed to remove this code at the same time. :)	12 years ago
Eric Snow	b282b3d804	Issue #18864 : Add a setter for ModuleSpec.has_location.	12 years ago
Brett Cannon	d2476c6e4b	Issue #19698 : Remove exec_module() from the built-in and extension module loaders. Due to the fact that the call signatures for extension modules and built-in modules does not allow for the specifying of what module to initialize and that on Windows all extension modules are built-in modules, work to clean up built-in and extension module initialization will have to wait until Python 3.5. Because of this the semantics of exec_module() would be incorrect, so removing the methods for now is the best option; load_module() is still used as a fallback by importlib and so this won't affect semantics.	12 years ago

Brett Cannon	f6901c8baa	Issue #19410 : Put back in special-casing of '' for importlib.machinery.FileFinder. While originally moved to stop special-casing '' as PathFinder farther up the typical call chain now uses the cwd in the instance of '', it was deemed an unnecessary risk to breaking subclasses of FileFinder to take the special-casing out.	12 years ago

Brett Cannon	58f5680462	Issue #18810 : Be optimistic with stat calls when seeing if a directory exists when checking for a package. Before there was an isdir check and then various isfile checks for possible __init__ files when looking for a package. This change drops the isdir check by leaning on the assumption that a directory will not contain something named after the module being imported which is not a directory. If the module is a package then it saves a stat call. If there is nothing in the directory with the potential package name it also saves a stat call. Only if there is something in the directory named the same thing as the potential package will the number of stat calls increase (due to more wasteful __init__ checks). Semantically there is no change as the isdir check moved down so that namespace packages continue to have no chance of accidentally collecting non-existent directories.	12 years ago
Brett Cannon	bb9e481efa	Issue #18416 : Fix various os calls in importlib.machinery.FileFinder now that self.path is no longer forced to '.'.	12 years ago
Brett Cannon	27e27f7ee1	Issue #18416 : Have importlib.machinery.PathFinder treat '' as the cwd and stop importlib.machinery.FileFinder treating '' as '.'. Previous PathFinder transformed '' into '.' which led to __file__ for modules imported from the cwd to always be relative paths. This meant the values of the attribute were wrong as soon as the cwd changed. This change now means that as long as the site module is run (which makes all entries in sys.path absolute) then all values for __file__ will also be absolute unless it's for __main__ when specified by file path in a relative way (modules imported by runpy will have an absolute path). Now that PathFinder is no longer treating '' as '.' it only makes sense for FileFinder to stop doing so as well. Now no transformation is performed for the directory given to the __init__ method. Thanks to Madison May for the initial patch.	12 years ago
