* OSError is the exception raised when one tries to create a directory thatBrett Cannon2010-08-261-2/+5

* Fix a bug where an attribute was lacking an object to work off of.Brett Cannon2010-08-241-1/+1
| | | | | Related to the fix for issue #9572. Thanks to Łukasz Czuja for catching the bug.
* One of the joys of having test_multiprocessing occasionally execute afterBrett Cannon2010-08-221-18/+26
| | | | | | | | | | | test_importlib is that it discovers special little race conditions. For instance, it turns out that importlib would throw an exception if two different Python processes both tried to create the __pycache__ directory as one process would succeed, causing the other process to fail as it didn't expect to get any "help". So now importlib simply stays calm and just accepts someone else did the work of creating the __pycache__ directory for it, moving on with life. Closes issue #9572.

* Make importlib.abc.SourceLoader the primary mechanism for importlib.Brett Cannon2010-07-032-27/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* Add an inheritance test for importlib.abc.SourceLoader.Brett Cannon2010-06-281-0/+5

* Move importlib.abc.SourceLoader to _bootstrap.Brett Cannon2010-06-283-105/+141
| | | | | | | | | | | Required updating code relying on other modules to switch to _bootstrap's unique module requirements. This led to the realization that get_code was being too liberal in its exception catching when calling set_data by blindly grabbing IOError. Shifted the responsibility of safely ignoring writes to a read-only path to set_data. Importlib is still not relying on SourceLoader yet; requires creating a SourcelessLoader and updating the source finder.

* Implement importlib.abc.SourceLoader and deprecate PyLoader and PyPycLoader.Brett Cannon2010-06-272-16/+654
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | SourceLoader is a simplification of both PyLoader and PyPycLoader. If one only wants to use source, then they need to only implement get_data and get_filename. To also use bytecode -- sourceless loading is not supported -- then two abstract methods -- path_mtime and set_data -- need to be implemented. Compared to PyLoader and PyPycLoader, there are less abstract methods introduced and bytecode files become an optimization controlled by the ABC and hidden from the user (this need came about as PEP 3147 showed that not treating bytecode as an optimization can cause problems for compatibility). PyLoader is deprecated in favor of SourceLoader. To be compatible from Python 3.1 onwards, a subclass need only use simple methods for source_path and is_package. Otherwise conditional subclassing based on whether Python 3.1 or Python 3.2 is being is the only change. The documentation and docstring for PyLoader explain what is exactly needed. PyPycLoader is deprecated also in favor of SourceLoader. Because PEP 3147 shifted bytecode path details so much, there is no foolproof way to provide backwards-compatibility with SourceLoader. Because of this the class is simply deprecated and users should move to SourceLoader (and optionally PyLoader for Python 3.1). This does lead to a loss of support for sourceless loading unfortunately. At some point before Python 3.2 is released, SourceLoader will be moved over to importlib._bootstrap so that the core code of importlib relies on the new code instead of the old PyPycLoader code. This commit is being done now so that there is no issue in having the API in Python 3.1a1.

| | | | | | | | | The file must be run using runpy. Certain tests are currently excluded from being run as they have known failures based on golden value checks that fail for various reasons (typically because __loader__ is not expected to be set on modules). Running the tests with this file does discover some incompatibilites in importlib that will be fixed in the near future (as noted currently in the docstring).

| | | | | | | | | importlib.abc.ResourceLoader, when in fact it did not. Fixed the ABC to inherit as documented. This doesn't introduce an backwards-incompatiblity as the code in PyLoader already required the single method ResourceLoader defined as an abstract method.
