Brett Cannon 9407d50208 Merge fix for issue #15111. 2012-10-10 19:18:37 -04:00
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.

Benjamin Peterson feaa54f537 don't depend on __debug__ because it's baked in at freeze time (issue #16046) 2012-09-25 11:22:59 -04:00
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 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).

which will make these two attributes required for loaders to set.

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.
