Benjamin Peterson d76bc7abac rollback 005fd1fe31ab (see #14609 and #14582)
Being able to overload a sys.module entry during import of a module was broken
by this changeset.

Brett Cannon 2ee61422ed Issue #13959: Re-implement imp.load_package() in imp.py.
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.

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.

Victor Stinner fe7c5b5bdf Issue #9319: Include the filename in "Non-UTF8 code ..." syntax error. 2011-04-05 01:48:03 +02:00
Brett Cannon 442c9b92d8 Make importlib compatible with __import__ by "fixing" code.co_filename
paths.

__import__ does a little trick when importing from bytecode by
back-patching the co_filename paths to point to the file location
where the code object was loaded from, *not* where the code object was
originally created. This allows co_filename to point to a valid path.
Problem is that co_filename is immutable from Python, so a private
function -- imp._fix_co_filename() -- had to be introduced in order to
get things working properly. Originally the plan was to add a file
argument to marshal.loads(), but that failed as the algorithm used by
__import__ is not fully recursive as one might expect, so to be fully
backwards-compatible the code used by __import__ needed to be exposed.

This closes issue #6811 by taking a different approach than outlined
in the issue.
