53089c6e91 Issue #15210: Greatly simplify the test for supporting importlib 
working without _frozen_importlib by moving to an import over a direct
access in sys.modules.

98979b85e7 Issue #15166: Re-implement imp.get_tag() using sys.implementation. 
Also eliminates some C code in Python/import.c as well.

Patch by Eric Snow with verification by comparing against another
patch from Jeff Knupp.

1e331560ee Closes #15030: Make importlib.abc.PyPycLoader respect the new .pyc 
file size header field.

Thanks to Marc Abramowitz and Ronan Lamy for helping out with various
parts of the patch.

48114b952b Issue #14657: The frozen instance of importlib used for bootstrap is now also the module imported as importlib._bootstrap. 2012-06-17 22:33:38 +02:00
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.

ea3eb88bca Issue #9260: A finer-grained import lock. 
Most of the import sequence now uses per-module locks rather than the
global import lock, eliminating well-known issues with threads and imports.

ee78a2b51c Issue #13959: Introduce importlib.find_loader(). 
The long-term goal is to deprecate imp.find_module() in favour of this
API, but it will take some time as some APIs explicitly return/use what
imp.find_module() returns.

c049952de7 Issue #13959: Have 
importlib.abc.FileLoader.load_module()/get_filename() and
importlib.machinery.ExtensionFileLoader.load_module() have their
single argument be optional as the loader's constructor has all the
ncessary information.

This allows for the deprecation of
imp.load_source()/load_compile()/load_package().

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.

2657df4744 Issue #13959: Re-implement imp.get_suffixes() in Lib/imp.py. 
This introduces a new function, imp.extension_suffixes(), which is
currently undocumented. That is forthcoming once issue #14657 is
resolved and how to expose file suffixes is decided.

efad00d520 Issue #14646: __import__() now sets __loader__ if need be. 
importlib.util.module_for_loader also will set __loader__ along with
__package__. This is in conjunction to a forthcoming update to PEP 302
which will make these two attributes required for loaders to set.

aa93642a35 Issue #14605: Use None in sys.path_importer_cache to represent no 
finder instead of using some (now non-existent) implicit finder.

ce418b448f Issue #14605: Stop having implicit entries for sys.meta_path.

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.

938d44d59c Issue #14605: Expose importlib.abc.FileLoader and 
importlib.machinery.(FileFinder, SourceFileLoader,
_SourcelessFileLoader, ExtensionFileLoader).

This exposes all of importlib's mechanisms that will become public on
the sys module.

24117a748b Issue #13959: Keep imp.get_magic() in C code, but cache in importlib 
for performance. While get_magic() could move to Lib/imp.py, having to
support PyImport_GetMagicNumber() would lead to equal, if not more, C
code than sticking with the status quo.
