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 a9976b3e32 Issue #16730: Don't raise an exception in 
importlib.machinery.FileFinder when the directory has become
unreadable or a file. This brings semantics in line with Python 3.2
import.

Reported and diagnosed by David Pritchard.

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 8ed677db12 Add some comments. 2012-09-28 16:41:39 -04:00
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.

Nick Coghlan a508770e20 Close #2501: Permission bits are once again correctly copied from the source file to the cached bytecode file. Test by Eric Snow. 2012-08-24 18:32:40 +10:00
Nick Coghlan 48fec05391 Close #14846: Handle a sys.path entry going away 2012-08-20 13:18:15 +10:00
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.

module again. Also took the opportunity to stop accidentally exporting
_imp.extension_suffixes() as public.
 2012-08-10 13:47:54 -04:00
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.

Patch by Eric Snow.
