  "message": "[mypyc] Fix crash on a property with another decorator (#22157)\n\nFixes mypyc/mypyc#1238.\n\nmypy only rejects decorators on top of `@property`, so it accepts a\nproperty like this:\n\n```python\nclass C:\n    @property\n    @functools.lru_cache(maxsize\u003dNone)\n    def p(self) -\u003e int: ...\n```\n\nIn a native class, `prepare_method_def()` left the getter out of\n`method_decls`, like any decorated method, but still set\n`is_prop_getter` and `property_types`. Reading `c.p` in compiled code\nthen generated a native `GetAttr` with no getter behind it, and the\ncompiler crashed in `emit_method_call` with `KeyError: \"\u0027C\u0027 has no\nattribute \u0027p\u0027\"`. If nothing compiled read the property, the module\ncompiled, but the method was missing from the type\u0027s method table, so\nthe decorator was called with the property\u0027s `getset_descriptor` and its\nresult replaced the property. With `lru_cache` the import failed\n(`TypeError: the first argument must be callable`).\n\nA getter with other decorators is now handled like other decorated\nmethods. `handle_ext_method()` applies the decorators, wraps the result\nwith `builtins.property` and sets it on the class. Non-native classes\nalready did this. The property isn\u0027t a native one, so compiled code\nreads it with a generic attribute lookup and coerces the result to the\ntype mypy inferred, which is the decorated function\u0027s return type.\n`@functools.cached_property` over another decorator takes the same path.\n\nA setter for such a property would need the native setter exposed as a\nPython callable, so for now it\u0027s reported as an error instead of\ncrashing:\n\n```\nerror: Property setter not supported when the getter has other decorators\n```\n\n`@property` over `@abstractmethod`, `@override` or `@final` isn\u0027t\naffected, since mypy removes those from the decorator list.\n\nA decorated property that overrides a native property still fails like a\ndecorated method that overrides a native method (mypyc/mypyc#767). This\nPR doesn\u0027t change that.",
