Antoine Pitrou bc07a5c913 Issue #15110: Fix the tracebacks generated by "import xxx" to not show the importlib stack frames. 2012-07-08 12:01:27 +02:00
Antoine Pitrou bc1a7ddc9b Check-in compiled importlib changes (you must run "make" after modifying the importlib sources). 2012-07-07 19:49:44 +02:00
Brett Cannon 98979b85e7 Issue #15166: Re-implement imp.get_tag() using sys.implementation.
Also eliminates some C code in Python/import.c as well.

Patch by Eric Snow with verification by comparing against another
patch from Jeff Knupp.

Antoine Pitrou 0ab5cf9b46 Issue #15181: importlib bytecode is unsigned and shouldn't have negative numbers.
This fixes a compiler warning with suncc.

Eric V. Smith e51a36922f Fixes issue 15039: namespace packages are no longer imported in preference to modules of the same name. 2012-06-24 19:13:55 -04:00

Antoine Pitrou 1d25b6f04a Issue #15103: remove the NUL character (serving as a Mercurial binary marker) from Python/importlib.h.
Instead the email notification hook uses a configuration option to omit importlib.h diffs.

Antoine Pitrou ea3eb88bca Issue #9260: A finer-grained import lock.
Most of the import sequence now uses per-module locks rather than the
global import lock, eliminating well-known issues with threads and imports.

Antoine Pitrou b84bc7a7ce Avoid "warning: no newline at end of file" in importlib.h. 2012-05-16 12:58:04 +02:00
Benjamin Peterson 6ecf8ce364 apparently importlib.h wants to be updated 2012-05-14 22:17:34 -07:00
Brett Cannon c049952de7 Issue #13959: Have
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().

Brett Cannon 2657df4744 Issue #13959: Re-implement imp.get_suffixes() in Lib/imp.py.
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.

Brett Cannon efad00d520 Issue #14646: __import__() now sets __loader__ if need be.
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.

Brett Cannon aa93642a35 Issue #14605: Use None in sys.path_importer_cache to represent no
finder instead of using some (now non-existent) implicit finder.
2012-04-27 15:30:58 -04:00
Brett Cannon ce418b448f Issue #14605: Stop having implicit entries for sys.meta_path.
ImportWarning is raised if sys.meta_path is found to be empty.
2012-04-27 14:01:58 -04:00
Brett Cannon e0d88a173c Issue #14605: Make explicit the entries on sys.path_hooks that used to
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.

Marc-Andre Lemburg 7541c8ea37 Issue #14605 and #14642:
Issue a warning in case Python\importlib.h needs to be rebuilt,
but there's no Python interpreter around to freeze the bootstrap
script.

Marc-Andre Lemburg 4fe29c9657 Issue #14605: Rename _SourcelessFileLoader to SourcelessFileLoader.
This time also recreating the Python/importlib.h file to make
make happy. See the ticket for details.
2012-04-25 02:31:37 +02:00
Brett Cannon 938d44d59c Issue #14605: Expose importlib.abc.FileLoader and
importlib.machinery.(FileFinder, SourceFileLoader,
_SourcelessFileLoader, ExtensionFileLoader).

This exposes all of importlib's mechanisms that will become public on
the sys module.

Brett Cannon 5c903e6ee1 Issue #13959: Continue to try to accomodate altsep in importlib by not
ignoring altsep if it already exists on a path when doing a join.
2012-04-22 11:45:07 -04:00
Brett Cannon cf649958f7 Revert to os.path.join() semantics for path manipulation in importlib
which is different than what imp.cache_from_source() operates on.

Brett Cannon 6c802b8491 Update importlib.h 2012-04-21 21:47:08 -04:00
Brett Cannon 0d05a7698b Have importlib look for pre-existing path separators when joining
paths.

Brett Cannon ed672d6872 Make path manipulation more robust for platforms with alternative path
separators.

Brett Cannon 24117a748b Issue #13959: Keep imp.get_magic() in C code, but cache in importlib
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.

Brett Cannon 8ff6baf25b Issue #14581: Windows users are allowed to import modules w/o taking
the file suffix's case into account, even when doing a case-sensitive
import.

Benjamin Peterson 665c3b3eec update importlib... 2012-04-18 15:29:52 -04:00
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.
2012-04-18 10:55:43 -04:00
Brett Cannon 7bd329d800 Issue #12599: Be more strict in accepting None vs. a false-like object
in importlib.

Thanks to PJE for pointing out the issue and Nick Coghlan for filing
the bug.

Brett Cannon 7ceedb8c1e Update importlib.h 2012-04-15 17:47:19 -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 49f8d8b016 Handle importing pkg.mod by executing
__import__('mod', {'__packaging__': 'pkg', level=1) w/o properly (and
thus not segfaulting).

Brett Cannon 59f9c3affc Rebuild importlib.h to incorporate added comments. 2012-04-14 21:18:48 -04:00
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__().
