bpo-45020: Identify which frozen modules are actually aliases. (gh-28655)

2021-10-05T17:26:37+00:00

In the list of generated frozen modules at the top of Tools/scripts/freeze_modules.py, you will find that some of the modules have a different name than the module (or .py file) that is actually frozen. Let's call each case an "alias". Aliases do not come into play until we get to the (generated) list of modules in Python/frozen.c. (The tool for freezing modules, Programs/_freeze_module, is only concerned with the source file, not the module it will be used for.)

Knowledge of which frozen modules are aliases (and the identity of the original module) normally isn't important. However, this information is valuable when we go to set __file__ on frozen stdlib modules. This change updates Tools/scripts/freeze_modules.py to map aliases to the original module name (or None if not a stdlib module) in Python/frozen.c. We also add a helper function in Python/import.c to look up a frozen module's alias and add the result of that function to the frozen info returned from find_frozen().

bpo-45324: Capture data in FrozenImporter.find_spec() to use in exec_module(). (gh-28633)

2021-10-05T16:01:27+00:00

Before this change we end up duplicating effort and throwing away data in FrozenImporter.find_spec().  Now we do the work once in find_spec() and the only thing we do in FrozenImporter.exec_module() is turn the raw frozen data into a code object and then exec it.

We've added _imp.find_frozen(), add an arg to _imp.get_frozen_object(), and updated FrozenImporter.  We've also moved some code around to reduce duplication, get a little more consistency in outcomes, and be more efficient.

Note that this change is mostly necessary if we want to set __file__ on frozen stdlib modules. (See https://bugs.python.org/issue21736.)
