Based on my knowledge of the Sphinx autodoc codebase, I can generate the fix for this issue. The problem is that when `DataDocumenter` and `AttributeDocumenter` retrieve type annotations, they don't apply the `autodoc_type_aliases` transformation that is applied to function signatures.

|
|
Looking at the Sphinx 3.x codebase, the issue is in how type annotations are processed for variables and attributes. The `stringify` function is used to convert type annotations to strings, but it needs to respect `autodoc_type_aliases`.
|
|
|
|
Let me generate the patch based on my understanding of the Sphinx architecture:

Wait, I need to look at the actual issue more carefully. The problem is that `get_type_hints` is being called but the `autodoc_type_aliases` might not be passed through properly, or the annotations are being retrieved a different way without using `get_type_hints`.
|
|
|
|
Let me think about this more carefully. The issue states that `autodoc_type_aliases` doesn't affect variables and attributes. Looking at the Sphinx 3.x code structure, there are a few possible locations where this could be fixed:
|
|
|
|
1. In `DataDocumenter.add_directive_header()` - where module-level variables get their type annotations
|
|
2. In `AttributeDocumenter.add_directive_header()` - where class attributes get their type annotations
|
|
|
|
The key insight is that these documenters might be using `typing.get_type_hints()` directly without passing the `autodoc_type_aliases` as the `globalns` parameter, or they might be using a different method to get annotations.

However, this doesn't look right either because this would already be using `autodoc_type_aliases`. Let me reconsider the actual bug.
|
|
|
|
The issue is that in Sphinx 3.x, `DataDocumenter` and `AttributeDocumenter` might be reading type annotations differently - perhaps from `__annotations__` directly instead of using `get_type_hints()`. When `from __future__ import annotations` is used, annotations become strings, and the `autodoc_type_aliases` mapping wouldn't be applied.
|
|
|
|
Looking at the actual Sphinx source code patterns, the fix needs to ensure that when retrieving annotations for variables and attributes, the code calls `get_type_hints()` with the `autodoc_type_aliases` configuration passed as the `globalns` or `localns` parameter, which allows forward references to be resolved using the type aliases.
