* | | Make importlib compatible with __import__ by "fixing" code.co_filenameBrett Cannon2011-03-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | paths. __import__ does a little trick when importing from bytecode by back-patching the co_filename paths to point to the file location where the code object was loaded from, *not* where the code object was originally created. This allows co_filename to point to a valid path. Problem is that co_filename is immutable from Python, so a private function -- imp._fix_co_filename() -- had to be introduced in order to get things working properly. Originally the plan was to add a file argument to marshal.loads(), but that failed as the algorithm used by __import__ is not fully recursive as one might expect, so to be fully backwards-compatible the code used by __import__ needed to be exposed. This closes issue #6811 by taking a different approach than outlined in the issue.
* | | Have importlib use the repr of a module name in error messages.Brett Cannon2011-03-231-1/+1
| | | | | | | | | | | | | | | | | | | | | This makes it obvious that an import failed because of some extraneous whitespace (e.g., a newline). This is a partial fix for issue #8754.

* | 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.

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).

* | 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.
