Robert Collins 1ae28d2ff3 Issue #20769: Improve reload() docs. Patch by Dorian Pula. 2015-08-05 08:20:53 +12:00
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.

R David Murray deed215313 Merge: #24081: Remove obsolete caveat from import docs. 2015-05-02 14:58:32 -04:00
R David Murray 6d877ef026 #24081: Remove obsolete caveat from import docs. 
Per Eric Snow's research, this changed in Python 2.4 in changeset 331e60d8ce,
but these docs were not updated.

Patch by Peter Viktorin.

Brett Cannon f299abdafa Issue #23731: Implement PEP 488. 
The concept of .pyo files no longer exists. Now .pyc files have an
optional `opt-` tag which specifies if any extra optimizations beyond
the peepholer were applied.

Brett Cannon 3fa84224fd Issue #23422: Clarify some things around importlib.import_module() 2015-02-20 10:34:20 -05:00
Brett Cannon 02d8454002 Issue #23014: Make importlib.abc.Loader.create_module() required when 
importlib.abc.Loader.exec_module() is also defined.

Before this change, create_module() was optional **and** could return
None to trigger default semantics. This change now reduces the
options for choosing default semantics to one and in the most
backporting-friendly way (define create_module() to return None).

Brett Cannon 2a17bde930 Issue #20383: Introduce importlib.util.module_from_spec(). 
Along the way, dismantle importlib._bootstrap._SpecMethods as it was
no longer relevant and constructing the new function required
partially dismantling the class anyway.

Brett Cannon 8d942296bb Issue #19719: Update various finder and loader ABCs such that their 
old methods now provide implementations when PEP 451 APIs are present.

This should help with backwards-compatibility with code which has not
been updated to work with PEP 451.

Brett Cannon f6901c8baa Issue #19410: Put back in special-casing of '' for 
importlib.machinery.FileFinder.

While originally moved to stop special-casing '' as PathFinder farther
up the typical call chain now uses the cwd in the instance of '', it
was deemed an unnecessary risk to breaking subclasses of FileFinder to
take the special-casing out.

Brett Cannon 27e27f7ee1 Issue #18416: Have importlib.machinery.PathFinder treat '' as the cwd 
and stop importlib.machinery.FileFinder treating '' as '.'.

Previous PathFinder transformed '' into '.' which led to __file__ for
modules imported from the cwd to always be relative paths. This meant
the values of the attribute were wrong as soon as the cwd changed.
This change now means that as long as the site module is run (which
makes all entries in sys.path absolute) then all values for __file__
will also be absolute unless it's for __main__ when specified by file
path in a relative way (modules imported by runpy will have an
absolute path).

Now that PathFinder is no longer treating '' as '.' it only makes
sense for FileFinder to stop doing so as well. Now no transformation
is performed for the directory given to the __init__ method.

Thanks to Madison May for the initial patch.
