…ongh-118532) We have only been tracking each module's PyModuleDef. However, there are some problems with that. For example, in some cases we load single-phase init extension modules from def->m_base.m_init or def->m_base.m_copy, but if multiple modules share a def then we can end up with unexpected behavior. With this change, we track the following: * PyModuleDef (same as before) * for some modules, its init function or a copy of its __dict__, but specific to that module * whether it is a builtin/core module or a "dynamic" extension * the interpreter (ID) that owns the cached __dict__ (only if cached) This also makes it easier to remember the module's kind (e.g. single-phase init) and if loading it previously failed, which I'm doing separately.
We're getting Does it sound like a CPython or ujson problem? |
Sorry for the delay. PyCon was a bit distracting. :) I'll take a look. |

The assertion was added in gh-118532 but was based on the invalid assumption that PyState_FindModule() would only be called with an already-initialized module def. I've added a test to make sure we don't make that assumption again.

We have only been tracking each module's
PyModuleDef
. However, there are some problems with that. For example, in some cases we load single-phase init extension modules fromdef->m_base.m_init
ordef->m_base.m_copy
, but if multiple modules share a def then we can end up with unexpected behavior.With this change, we track the following:
PyModuleDef
(same as before)__dict__
, but specific to that module__dict__
(only if cached)This also makes it easier to remember the module's kind (e.g. single-phase init) and if loading it previously failed, which I'm doing in another PR.
