Brett Cannon 5650e4f41c Issue #15627: Add the compile_source() method to
importlib.abc.SourceLoader.

This provides an easy hook into the import system to allow for source
transformations, AST optimizations, etc.

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.

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 ba0a3edd26 Issue #2051: Tweak last commit for this issue to pass in mode instead
of source path to set_data() and make the new argument private until
possible API changes can be discussed more thoroughly in Python 3.4.

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.

Brett Cannon f4dc9204cc Issue #15502: Finish bringing importlib.abc in line with the current
state of the import system. Also make importlib.invalidate_caches()
work with sys.meta_path instead of sys.path_importer_cache to
completely separate the path-based import system from the overall
import system.

Brett Cannon a6473f9cfd Issues #15169, #14599: Make PyImport_ExecCodeModuleWithPathnames() use
Lib/imp.py for imp.source_from_cache() instead of its own C version.

Also change PyImport_ExecCodeModuleObject() to not infer the source
path from the bytecode path like
PyImport_ExecCodeModuleWithPathnames() does. This makes the function
less magical.

This also has the side-effect of removing all uses of MAXPATHLEN in
Python/import.c which can cause failures on really long filenames.

Brett Cannon 461c813164 Issue #15111: When a module was imported using a 'from import'
statement (e.g. ``from distutils import msvc9compiler``) that triggers
an ImportError of its own (e.g. the non-existence of winreg), let that
exception propagate instead of raising a generic ImportError for the
module being requested (e.g. msvc9compiler).

patch from Jeff Knupp.

Brett Cannon ea0b823940 Issue #14938: importlib.abc.SourceLoader.is_package() now takes the
module name into consideration when determining whether a module is a
package or not. This prevents importing a module's __init__ module
directly and having it considered a package, which can lead to
duplicate sub-modules.

Thanks to Ronan Lamy for reporting the bug.
