Serhiy Storchaka 48a583b1d8 Issue #25698: Prevent possible replacing imported module with the empty one
if the stack is too deep.
2016-02-10 10:31:20 +02:00
Brett Cannon 9fa812668f Issue #18018: Raise an ImportError if a relative import is attempted
with no known parent package.

Previously SystemError was raised if the parent package didn't exist
(e.g., __package__ was set to '').
Thanks to Florent Xicluna and Yongzhi Pan for reporting the issue.

Brett Cannon 849113af6b Issue #25791: Warn when __package__ != __spec__.parent.
In a previous change, __spec__.parent was prioritized over
__package__. That is a backwards-compatibility break, but we do
eventually want __spec__ to be the ground truth for module details. So
this change reverts the change in semantics and instead raises an
ImportWarning when __package__ != __spec__.parent to give people time
to adjust to using spec objects.

Brett Cannon 63b8505281 Issue #25791: Raise an ImportWarning when __spec__ or __package__ are
not defined for a relative import.

This is the start of work to try and clean up import semantics to rely
more on a module's spec than on the myriad attributes that get set on
a module. Thanks to Rose Ames for the patch.

Nick Coghlan d5cacbb1d9 PEP 489: Multi-phase extension module initialization
Known limitations of the current implementation:

- documentation changes are incomplete
- there's a reference leak I haven't tracked down yet

The leak is most visible by running:

  ./python -m test -R3:3 test_importlib

However, you can also see it by running:

  ./python -X showrefcount

Importing the array or _testmultiphase modules, and
then deleting them from both sys.modules and the local
namespace shows significant increases in the total
number of active references each cycle. By contrast,
with _testcapi (which continues to use single-phase
initialisation) the global refcounts stabilise after
a couple of cycles.

Larry Hastings 2623c8c23c Issue #20530: Argument Clinic's signature format has been revised again.
The new syntax is highly human readable while still preventing false
positives.  The syntax also extends Python syntax to denote "self" and
positional-only parameters, allowing inspect.Signature objects to be
totally accurate for all supported builtins in Python 3.4.

Larry Hastings 581ee3618c Issue #20326: Argument Clinic now uses a simple, unique signature to
annotate text signatures in docstrings, resulting in fewer false
positives.  "self" parameters are also explicitly marked, allowing
inspect.Signature() to authoritatively detect (and skip) said parameters.

Issue #20326: Argument Clinic now generates separate checksums for the
input and output sections of the block, allowing external tools to verify
that the input has not changed (and thus the output is not out-of-date).

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 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.

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.

importlib._bootstrap is now frozen into Python/importlib.h and stored

code along with sys and imp and then uses _frozen_importlib._install()
to set builtins.__import__() w/ _frozen_importlib.__import__().

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.

Brett Cannon bc2eff3112 PyImport_Import was using the old import hack of sticking a dummy value into
fromlist to get __import__ to return the module desired. Now it uses the proper
approach of fetching the module from sys.modules.

Closes issue #9252. Thanks to Alexander Belopolsky for the bug report.

  Turned out that if you used explicit relative import syntax
  (e.g. from .os import sep) and it failed, import would still try the implicit
  relative import semantics of an absolute import (from os import sep). That's
  not right, so when level is negative, only do explicit relative import
  semantics.

  Fixes issue #7902. Thanks to Meador Inge for the patch.
