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__().

Brett Cannon 927d87470a If a module injects something into sys.modules as a side-effect of
importation, then respect that injection.

Discovered thanks to Lib/xml/parsers/expat.py injecting
xml.parsers.expat.errors and etree now importing that directly as a
module.

Brett Cannon f58d45c649 Tweak the handling of the empty string in sys.path for importlib.
It seems better to cache the finder for the cwd under its full path
insetad of '' in case the cwd changes. Otherwise FileFinder needs to
dynamically change itself based on whether it is given '' instead of
caching a finder for every change to the cwd.

Antoine Pitrou 707033a694 Issue #13146: Writing a pyc file is now atomic under POSIX. 2011-10-17 19:28:44 +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.

Brett Cannon a7468bc5c6 Have importlib use the repr of a module name in error messages.
This makes it obvious that an import failed because of some extraneous

Brett Cannon ee6d64773b One of the joys of having test_multiprocessing occasionally execute after
test_importlib is that it discovers special little race conditions. For
instance, it turns out that importlib would throw an exception if two different
Python processes both tried to create the __pycache__ directory as one process
would succeed, causing the other process to fail as it didn't expect to get any
"help". So now importlib simply stays calm and just accepts someone else did
the work of creating the __pycache__ directory for it, moving on with life.

Closes issue #9572.

Brett Cannon 418182e18b Make importlib.abc.SourceLoader the primary mechanism for importlib.
This required moving the class from importlib/abc.py into
importlib/_bootstrap.py and jiggering some code to work better with the class.
This included changing how the file finder worked to better meet import
semantics. This also led to fixing importlib to handle the empty string from
sys.path as import currently does (and making me wish we didn't support that
instead just required people to insert '.' instead to represent cwd).

It also required making the new set_data abstractmethod create
any needed subdirectories implicitly thanks to __pycache__ (it was either this
or grow the SourceLoader ABC to gain an 'exists' method and either a mkdir
method or have set_data with no data arg mean to create a directory).

Lastly, as an optimization the file loaders cache the file path where the
finder found something to use for loading (this is thanks to having a
sourceless loader separate from the source loader to simplify the code and
cut out stat calls).
Unfortunately test_runpy assumed a loader would always work for a module, even
if you changed from underneath it what it was expected to work with. By simply
dropping the previous loader in test_runpy so the proper loader can be returned
by the finder fixed the failure.

At this point importlib deviates from import on two points:

1. The exception raised when trying to import a file is different (import does
an explicit file check to print a special message, importlib just says the path
cannot be imported as if it was just some module name).

2. the co_filename on a code object is not being set to where bytecode was
actually loaded from instead of where the marshalled code object originally
came from (a solution for this has already been agreed upon on python-dev but has
not been implemented yet; issue8611).

Brett Cannon 0cf9e6a621 Move importlib.abc.SourceLoader to _bootstrap.
Required updating code relying on other modules to switch to _bootstrap's
unique module requirements. This led to the realization that
get_code was being too liberal in its exception catching when calling set_data
by blindly grabbing IOError. Shifted the responsibility of safely ignoring
writes to a read-only path to set_data.

Importlib is still not relying on SourceLoader yet; requires creating a
SourcelessLoader and updating the source finder.

Brett Cannon 94aaf9e4b8 Relocate source_mtime in importlib to PyPycLoader. 2009-02-21 23:12:24 +00:00
Brett Cannon 91cf882b36 Refactor source and bytecode file loaders in importlib so that there
are source-only and source/bytecode loaders.
2009-02-21 05:41:15 +00:00
Brett Cannon 0515619dbc Tweak the source/bytecode loader from importlib to use more of the PEP 302
protocol API.
2009-02-21 03:53:06 +00:00
Brett Cannon 4afab6b30b Separate out finder for source and source/bytecode. 2009-02-21 03:31:35 +00:00
Brett Cannon 2dee597e05 Do some cleanup in importlib:
+ Ditch using arguments to super().
+ Ditch subclassing from object directly.
+ Move directory check out of chaining path hook to file path hook/finder.
+ Rename some classes to better reflect they are finders, not importers.
2009-02-21 03:15:37 +00:00
Brett Cannon d2e7b33815 Implement the more specific PEP 302 semantics for loaders and what happens upon
load failure in relation to reloads. Also expose
importlib.util.module_for_loader to handle all of the details of this along
with making sure all current loaders behave nicely.
2009-02-17 02:45:03 +00:00
Brett Cannon 32732e3fbd Change importlib.machinery.PathFinder to not have implicit semantics (that's
not handled by importlib._bootstrap._DefaultPathFinder).
2009-02-15 05:48:13 +00:00
Brett Cannon 51d8bfc837 Create a simple substitute for functools.wraps to use in importlib._bootstrap. 2009-02-07 02:13:28 +00:00
Brett Cannon 06c9d96b70 Move importlib completely over to using rpartition and accepting the empty
string for top-level modules.
2009-02-07 01:52:25 +00:00
Brett Cannon d94e558fdc Move importlib's built-in importer to use rpartition for __package__. 2009-02-07 01:40:19 +00:00
Brett Cannon eb2e0dd19d Move importlib's frozen importer over to rpartition for setting __package__. 2009-02-07 01:38:38 +00:00
Brett Cannon 2c318a1390 Rewrite the code implementing __import__ for importlib. Now it is much simpler
and relies much more on meta path finders to abstract out various parts of
import.

As part of this the semantics for import_module tightened up and now follow
__import__ much more closely (biggest thing is that the 'package' argument must
now already be imported, else a SystemError is raised).
2009-02-07 01:15:27 +00:00
Brett Cannon 7f9876c0da Initial, untested stab at writing a common denominator function for __import__
and import_module.
2009-02-06 02:47:33 +00:00
Brett Cannon 1f9bcd38a9 Add tests for using sys.path_hooks by importlib.machinery.PathFinder. 2009-02-05 23:36:02 +00:00
Brett Cannon f7e5a8c724 Rename importlib._bootstrap.SysPathFinder to PathFinder and expose off of
importlib.machinery. Also make the methods either class or staticmethods.
2009-02-05 02:52:18 +00:00
Brett Cannon 1d376687b7 To prevent another screw-up on my part where my prototype gets lost thanks to
an ``svn revert`` (gee, maybe more atomic commits by use of something like a
DVCS would help with this? Wish someone would get on that ...), I am checking
in an untested, work-in-progress meta path finder to handle sys.path.
2009-02-02 19:19:36 +00:00
Brett Cannon 776e7014e9 Simplify write_bytecode for importlib. 2009-02-01 06:07:57 +00:00
Brett Cannon ba96f0f89a Ditch read_source() and read_bytecode() and replace with *_path() and
get_data().
2009-02-01 05:43:31 +00:00
Brett Cannon 51c502689c Expose source_path and bytecode_path on _PyFileLoader. 2009-02-01 05:33:17 +00:00
Brett Cannon 223a19d8b1 Fix importlib.machinery.FrozenImporter.load_module() to set __package__
properly. Discovered by also moving the loader tests over to
importlib.test.abc.LoaderTests.
2009-02-01 01:34:13 +00:00
Brett Cannon 78246b6b45 Document both importlib.machinery.BuiltinImporter and FrozenImporter. 2009-01-25 04:56:30 +00:00
Brett Cannon 5abdc93eb8 Add importlib.machinery with its first tenants, BuitinImporter and
FrozenImporter. Docs forthcoming.

I plan on all finders and loaders (and most likely hooks) to live
in imoprtlib.machinery. Utility stuff will end up in importlib.util.
Higher-level API stuff will stay on imoprtlib directly (e.g. import_module).
2009-01-22 22:43:07 +00:00
Brett Cannon b4a1b8c541 Fix a typo in some code that is not tested or supported yet.
Closes issue 4993. Thanks Antoine Pitrou for the catch.
2009-01-19 06:56:16 +00:00
Brett Cannon 23cbd8a656 Add initial implementation of importlib. See the NOTES files for what is
planned for the package.

There are no docs yet, but they are coming once the API for the first new
function, importlib.import_module() is finalized.
