This exposes all of importlib's mechanisms that will become public on
the sys module.]]> Brett Cannon <brett@python.org> Sun, 22 Apr 2012 19:58:33 -0400 https://hg.dopieralski.pl/cpython-lru_cache-weakref/log/2dd046be2c88/Lib/importlib/test/source/test_source_encoding.py
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 <brett@python.org> Sat, 14 Apr 2012 14:10:13 -0400 https://hg.dopieralski.pl/cpython-lru_cache-weakref/log/34d827249ce0/Lib/importlib/test/source/test_source_encoding.py
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 <bcannon@gmail.com> Sat, 03 Jul 2010 21:48:25 +0000 https://hg.dopieralski.pl/cpython-lru_cache-weakref/log/7b69e630d237/Lib/importlib/test/source/test_source_encoding.py Barry Warsaw <barry@python.org> Sat, 17 Apr 2010 00:19:56 +0000 https://hg.dopieralski.pl/cpython-lru_cache-weakref/log/b65ebed06eb0/Lib/importlib/test/source/test_source_encoding.py
Obviously one shouldn't do whole sale conversions like this, but I was already
going through the test code and I was bored at the airport.]]> Brett Cannon <bcannon@gmail.com> Thu, 27 Aug 2009 23:49:21 +0000 https://hg.dopieralski.pl/cpython-lru_cache-weakref/log/04a5b6438526/Lib/importlib/test/source/test_source_encoding.py Brett Cannon <bcannon@gmail.com> Thu, 12 Mar 2009 22:47:53 +0000 https://hg.dopieralski.pl/cpython-lru_cache-weakref/log/ee7029710c05/Lib/importlib/test/source/test_source_encoding.py are source-only and source/bytecode loaders.]]> Brett Cannon <bcannon@gmail.com> Sat, 21 Feb 2009 05:41:15 +0000 https://hg.dopieralski.pl/cpython-lru_cache-weakref/log/d85ef26efd10/Lib/importlib/test/source/test_source_encoding.py Brett Cannon <bcannon@gmail.com> Sun, 01 Feb 2009 04:00:05 +0000 https://hg.dopieralski.pl/cpython-lru_cache-weakref/log/4b3246c83e3f/Lib/importlib/test/source/test_source_encoding.py importlib.test.support to importlib.test.source.util.]]> Brett Cannon <bcannon@gmail.com> Sun, 01 Feb 2009 03:08:31 +0000 https://hg.dopieralski.pl/cpython-lru_cache-weakref/log/aac51b70c74c/Lib/importlib/test/source/test_source_encoding.py planned for the package.
