Brett Cannon	938d44d59c	Issue #14605 : Expose importlib.abc.FileLoader and importlib.machinery.(FileFinder, SourceFileLoader, _SourcelessFileLoader, ExtensionFileLoader). This exposes all of importlib's mechanisms that will become public on the sys module.	14 years ago
Brett Cannon	fd0741555b	Issue #2377 : Make importlib the implementation of __import__(). importlib._bootstrap is now frozen into Python/importlib.h and stored as _frozen_importlib in sys.modules. Py_Initialize() loads the frozen code along with sys and imp and then uses _frozen_importlib._install() to set builtins.__import__() w/ _frozen_importlib.__import__().	14 years ago
Brett Cannon	61b14251d3	Make importlib.abc.SourceLoader the primary mechanism for importlib. This required moving the class from importlib/abc.py into importlib/_bootstrap.py and jiggering some code to work better with the class. This included changing how the file finder worked to better meet import semantics. This also led to fixing importlib to handle the empty string from sys.path as import currently does (and making me wish we didn't support that instead just required people to insert '.' instead to represent cwd). It also required making the new set_data abstractmethod create any needed subdirectories implicitly thanks to __pycache__ (it was either this or grow the SourceLoader ABC to gain an 'exists' method and either a mkdir method or have set_data with no data arg mean to create a directory). Lastly, as an optimization the file loaders cache the file path where the finder found something to use for loading (this is thanks to having a sourceless loader separate from the source loader to simplify the code and cut out stat calls). Unfortunately test_runpy assumed a loader would always work for a module, even if you changed from underneath it what it was expected to work with. By simply dropping the previous loader in test_runpy so the proper loader can be returned by the finder fixed the failure. At this point importlib deviates from import on two points: 1. The exception raised when trying to import a file is different (import does an explicit file check to print a special message, importlib just says the path cannot be imported as if it was just some module name). 2. the co_filename on a code object is not being set to where bytecode was actually loaded from instead of where the marshalled code object originally came from (a solution for this has already been agreed upon on python-dev but has not been implemented yet; issue8611).	16 years ago

Brett Cannon	2153dc001f	Move over to using assertRaises as a context manager for importlib tests. Obviously one shouldn't do whole sale conversions like this, but I was already going through the test code and I was bored at the airport.	17 years ago
Brett Cannon	f87e04d339	Finish properly hiding importlib implementation code.	17 years ago
Brett Cannon	91cf882b36	Refactor source and bytecode file loaders in importlib so that there are source-only and source/bytecode loaders.	17 years ago
Brett Cannon	bcb26c53c0	Rename importlib.test.support to importlib.test.util.	17 years ago
Brett Cannon	4ee2cdaf65	Split out support code that is specific to source tests out of importlib.test.support to importlib.test.source.util.	17 years ago
Brett Cannon	23cbd8a656	Add initial implementation of importlib. See the NOTES files for what is planned for the package. There are no docs yet, but they are coming once the API for the first new function, importlib.import_module() is finalized.	17 years ago
