Brett Cannon 82da8886cc Issue #15767: Revert 3a50025f1900 for ModuleNotFoundError 2013-07-04 17:48:16 -04:00
Christian Heimes 582cfbbf74 import.c does neither need mode_t nor _mkdir() anymore 2013-06-23 15:53:09 +02:00
Brett Cannon 8f5ac5106e Issue #15767: Touch up ModuleNotFoundError usage by import. 
Forgot to raise ModuleNotFoundError when None is found in sys.modules.
This led to introducing the C function PyErr_SetImportErrorSubclass()
to make setting ModuleNotFoundError easier.

Also updated the reference docs to mention ModuleNotFoundError
appropriately. Updated the docs for ModuleNotFoundError to mention the
None in sys.modules case.

Lastly, it was noticed that PyErr_SetImportError() was not setting an
exception when returning None in one case. That issue is now fixed.

Brett Cannon 3e0651b5fa Issue #18065: For frozen packages set __path__ to []. 
Previously __path__ was set to [__name__], but that could lead to bad
results if someone managed to circumvent the frozen importer and
somehow ended up with a finder that thought __name__ was a legit
directory/location.

Nick Coghlan 5ee9892406 Close #15425: Eliminate more importlib related traceback noise 2012-07-29 20:30:36 +10:00
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.

resolved and how to expose file suffixes is decided.

Thanks to Eric Snow for helping with imp.load_module() (previous
commit) which led to the removal of a bunch of C code.

Brett Cannon 01a76171a0 Issue #13959: Re-implement imp.load_module() in imp.py. 2012-04-15 20:25:23 -04:00
Brett Cannon 8a1d04c643 Issue #13959: Simplify imp.reload() by relying on a module's 
__loader__.

Since import now sets __loader__ on all modules it creates and
imp.reload() already relied on the attribute for modules that import
didn't create, the only potential compatibility issue is if people
were deleting the attribute on modules and expecting imp.reload() to
continue to work.
 2012-04-15 17:56:09 -04:00
Brett Cannon 6f44d66bc4 Issue #13959: Rename imp to _imp and add Lib/imp.py and begin 
rewriting functionality in pure Python.

To start, imp.new_module() has been rewritten in pure Python, put into
importlib (privately) and then publicly exposed in imp.

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.

Brett Cannon fd0741555b Issue #2377: Make importlib the implementation of __import__(). 
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__().

Benjamin Peterson 2afe6aeae8 perform yield from delegation by repeating YIELD_FROM opcode (closes #14230) 
This allows generators that are using yield from to be seen by debuggers. It
also kills the f_yieldfrom field on frame objects.

Patch mostly from Mark Shannon with a few tweaks by me.
