* Silence the FileExistsError which can be raised because of the O_EXCL flagAntoine Pitrou2011-10-191-7/+7

* Issue #13146: Writing a pyc file is now atomic under POSIX.Antoine Pitrou2011-10-171-3/+23

* 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.
* | Make importlib.abc.SourceLoader the primary mechanism for importlib.Brett Cannon2010-07-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* | Move importlib.abc.SourceLoader to _bootstrap.Brett Cannon2010-06-281-0/+137
| | | | | | | | | | | | | | | | | | | | | | 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.
