Brett Cannon a6ce4fd426 Closes issue #15111: Calling __import__ with a module specified in
fromlist which causes its own ImportError (e.g. the module tries to
import a non-existent module) should have that exception propagate.

Christian Heimes 6d29352cfd Issue #15895: my analysis was slightly off. The FILE pointer is only leaked when set_main_loader() fails for a pyc file with closeit=0. In the success case run_pyc_file() does its own cleanup of the fp. I've changed the code to use another FILE ptr for pyc files and moved the fclose() to PyRun_SimpleFileExFlags() to make it more obvious what's happening. 2012-09-11 15:47:28 +02:00

Antoine Pitrou 5b4faae307 Issue #13992: The trashcan mechanism is now thread-safe. This eliminates
sporadic crashes in multi-thread programs when several long deallocator
chains ran concurrently and involved subclasses of built-in container
types.

Note that the trashcan functions are part of the stable ABI, therefore
they have to be kept around for binary compatibility of extensions.

Antoine Pitrou 56cd62c04a Issue #13992: The trashcan mechanism is now thread-safe. This eliminates
sporadic crashes in multi-thread programs when several long deallocator
chains ran concurrently and involved subclasses of built-in container
types.

Because of this change, a couple extension modules compiled for 3.2.4
(those which use the trashcan mechanism, despite it being undocumented)
will not be loadable by 3.2.3 and earlier. However, extension modules
compiled for 3.2.3 and earlier will be loadable by 3.2.4.

Antoine Pitrou 4f0338cab7 Issue #15781: Fix two small race conditions in import's module locking. 2012-08-28 00:24:52 +02:00
Brett Cannon 12c6bda4f0 Issue #15316: Let exceptions raised during imports triggered by the
fromlist of __import__ propagate.

The problem previously was that if something listed in fromlist didn't
exist then that's okay. The fix for that was too broad in terms of
catching ImportError.

The trick with the solution to this issue is that the proper
refactoring of import thanks to importlib doesn't allow for a way to
distinguish (portably) between an ImportError because finders couldn't
find a loader, or a loader raised the exception. In Python 3.4 the
hope is to introduce a new exception (e.g. ModuleNotFound) to make it
clean to differentiate why ImportError was raised.

Brett Cannon 7385adc84c Issue #15715: Ignore failed imports triggered by the use of fromlist.
When the fromlist argument is specified for __import__() and the
attribute doesn't already exist, an import is attempted. If that fails
(e.g. module doesn't exist), the ImportError will now be silenced (for
backwards-compatibility). This *does not* affect
``from ... import ...`` statements.

Thanks to Eric Snow for the patch and Simon Feltman for reporting the
regression.
