gh-101758: Add a Test For Single-Phase Init Module Variants (gh-101891)
The new test exercises the most important variants for single-phase init extension modules. We also add some explanation about those variants to import.c. https://github.com/python/cpython/issues/101758

/*
|
||||
We support a number of kinds of single-phase init builtin/extension modules:
|
||||
|
||||
* "basic"
|
||||
* no module state (PyModuleDef.m_size == -1)
|
||||
* does not support repeated init (we use PyModuleDef.m_base.m_copy)
|
||||
* may have process-global state
|
||||
* the module's def is cached in _PyRuntime.imports.extensions,
|
||||
by (name, filename)
|
||||
* "reinit"
|
||||
* no module state (PyModuleDef.m_size == 0)
|
||||
* supports repeated init (m_copy is never used)
|
||||
* should not have any process-global state
|
||||
* its def is never cached in _PyRuntime.imports.extensions
|
||||
(except, currently, under the main interpreter, for some reason)
|
||||
* "with state" (almost the same as reinit)
|
||||
* has module state (PyModuleDef.m_size > 0)
|
||||
* supports repeated init (m_copy is never used)
|
||||
* should not have any process-global state
|
||||
* its def is never cached in _PyRuntime.imports.extensions
|
||||
(except, currently, under the main interpreter, for some reason)
|
||||
|
||||
There are also variants within those classes:
|
||||
|
||||
* two or more modules share a PyModuleDef
|
||||
* a module's init func uses another module's PyModuleDef
|
||||
* a module's init func calls another's module's init func
|
||||
* a module's init "func" is actually a variable statically initialized
|
||||
to another module's init func
|
||||
* two or modules share "methods"
|
||||
* a module's init func copies another module's PyModuleDef
|
||||
(with a different name)
|
||||
* (basic-only) two or modules share process-global state
|
||||
|
||||
In the first case, where modules share a PyModuleDef, the following
|
||||
notable weirdness happens:
|
||||
|
||||
* the module's __name__ matches the def, not the requested name
|
||||
* the last module (with the same def) to be imported for the first time wins
|
||||
* returned by PyState_Find_Module() (via interp->modules_by_index)
|
||||
* (non-basic-only) its init func is used when re-loading any of them
|
||||
(via the def's m_init)
|
||||
* (basic-only) the copy of its __dict__ is used when re-loading any of them
|
||||
(via the def's m_copy)
|
||||
|
||||
However, the following happens as expected:
|
||||
|
||||
* a new module object (with its own __dict__) is created for each request
|
||||
* the module's __spec__ has the requested name
|
||||
* the loaded module is cached in sys.modules under the requested name
|
||||
* the m_index field of the shared def is not changed,
|
||||
so at least PyState_FindModule() will always look in the same place
|
||||
|
||||
For "basic" modules there are other quirks:
|
||||
|
||||
* (whether sharing a def or not) when loaded the first time,
|
||||
m_copy is set before _init_module_attrs() is called
|
||||
in importlib._bootstrap.module_from_spec(),
|
||||
so when the module is re-loaded, the previous value
|
||||
for __wpec__ (and others) is reset, possibly unexpectedly.
|
||||
|
||||
Generally, when multiple interpreters are involved, some of the above
|
||||
gets even messier.
