Brett Cannon 100883f0cb Issue #17093,17566,17567: Methods from classes in importlib.abc now raise/return
the default exception/value when called instead of raising/returning
NotimplementedError/NotImplemented (except where appropriate).
This should allow for the ABCs to act as the bottom/end of the MRO with expected
default results.

As part of this work, also make importlib.abc.Loader.module_repr()
optional instead of an abstractmethod.

Brett Cannon 327992330e Issue #17099: Have importlib.find_loader() raise ValueError when
__loader__ is not set on a module. This brings the exception in line
with when __loader__ is None (which is equivalent to not having the
attribute defined).

Brett Cannon c190389834 Issue #17220: two fixes for changeset 2528e4aea338.
First, because the mtime can exceed 4 bytes, make sure to mask it down to 4
bytes before getting its little-endian representation for writing out to a .pyc
file.

Two, cap an rsplit() call to 1 split, else can lead to too many values being
returned for unpacking.

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.

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 cb66eb0dec Issue #13959: Deprecate imp.get_suffixes() for new attributes on
importlib.machinery that provide the suffix details for import.
The attributes were not put on imp so as to compartmentalize
everything importlib needs for setting up imports in
importlib.machinery.

This also led to an indirect deprecation of inspect.getmoduleinfo() as
it directly returned imp.get_suffix's returned tuple which no longer
makes sense.

ImportWarning is raised if sys.meta_path is found to be empty.
2012-04-27 14:01:58 -04:00
Brett Cannon e0d88a173c Issue #14605: Make explicit the entries on sys.path_hooks that used to
be implicit.

Added a warning for when sys.path_hooks is found to be empty. Also
changed the meaning of None in sys.path_importer_cache to represent
trying sys.path_hooks again (an interpretation of previous semantics).
Also added a warning for when None was found.

The long-term goal is for None in sys.path_importer_cache to represent
the same as imp.NullImporter: no finder found for that sys.path entry.

Brett Cannon 881535b726 Issue #14582: Import returns the module returned by a loader instead
of sys.modules when possible.

This is being done for two reasons. One is to gain a little bit of
performance by skipping an unnecessary dict lookup in sys.modules. But
the other (and main) reason is to be a little bit more clear in how
things should work from the perspective of import's interactions with
loaders. Otherwise loaders can easily forget to return the module even
though PEP 302 explicitly states they are expected to return the module
they loaded.

importlib._bootstrap is now frozen into Python/importlib.h and stored

code along with sys and imp and then uses _frozen_importlib._install()
to set builtins.__import__() w/ _frozen_importlib.__import__().

Brett Cannon f58d45c649 Tweak the handling of the empty string in sys.path for importlib.
It seems better to cache the finder for the cwd under its full path

caching a finder for every change to the cwd.
