* Prevent test_inspect from keeping alive a ton of frames and local variables ↵Antoine Pitrou2012-06-171-1/+1
| | | | | | by way of a global variable keeping a reference to a traceback. Should fix some buildbot failures.

| | | | | | | | | 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.

* Issue #9260: A finer-grained import lock.Antoine Pitrou2012-05-172-13/+293
| | | | | Most of the import sequence now uses per-module locks rather than the global import lock, eliminating well-known issues with threads and imports.

* Issue #13959: Introduce importlib.find_loader().Brett Cannon2012-05-122-1/+73
| | | | | | 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.
* Issue #13959: HaveBrett Cannon2012-05-113-10/+59
| | | | | | | | | | 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().
* Issue #13959: Deprecate imp.get_suffixes() for new attributes onBrett Cannon2012-05-117-34/+45
| | | | | | | | | | | 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.
* Issue #14764: Update importlib.test.benchmark to work in a world whereBrett Cannon2012-05-111-0/+14
| | | | import machinery is no longer implicit.

* Issue #13959: Re-implement imp.get_suffixes() in Lib/imp.py.Brett Cannon2012-05-047-51/+14
| | | | | | 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.
* Properly mark names in importlib._bootstrap as private.Brett Cannon2012-05-041-31/+31

* Issue #14646: __import__() now sets __loader__ if need be.Brett Cannon2012-04-272-3/+53
| | | | | | 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.

* Issue #14605: Stop having implicit entries for sys.meta_path.Brett Cannon2012-04-272-4/+22
| | | | ImportWarning is raised if sys.meta_path is found to be empty.
* Issue #14605: Make explicit the entries on sys.path_hooks that used toBrett Cannon2012-04-263-104/+46
| | | | | | | | | | | | 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.
* Issue #14605 and #14642:Marc-Andre Lemburg2012-04-251-0/+7
| | | | | | Issue a warning in case Python\importlib.h needs to be rebuilt, but there's no Python interpreter around to freeze the bootstrap script.

* Issue #13959: Keep imp.get_magic() in C code, but cache in importlibBrett Cannon2012-04-201-4/+8
| | | | | | 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.

* | Issue #14582: Import returns the module returned by a loader insteadBrett Cannon2012-04-152-34/+14
|/ | | | | | | | | | | | 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 as _frozen_importlib in sys.modules. Py_Initialize() loads the frozen code along with sys and imp and then uses _frozen_importlib._install() to set builtins.__import__() w/ _frozen_importlib.__import__().
