rustc_lint: handle more method calls in unconditional_recursion.

2015-08-03T22:17:56+00:00

lint: default methods must be called on Self to unconditionally recur.

2015-06-29T23:00:54+00:00

This catches the case when a trait defines a default method that calls itself, but on a type that isn't necessarily `Self`, e.g. there's no reason that `T = Self` in the following, so the call isn't necessarily recursive (`T` may override the call). trait Bar { fn method(&self, x: &T) { x.method(x) } } Fixes #26333.

lint: only consider actual calls as unconditional recursion.

2015-06-29T22:59:37+00:00

Specifically, just mentioning the function name as a value is fine, as long as it isn't called, e.g. `fn main() { let _ = main; }`. Closes #21705.

Add a lint to detect unconditional recursion.

2015-01-24T13:21:03+00:00

E.g. `fn foo() { foo() }`, or, more subtlely impl Foo for Box { fn bar(&self) { self.bar(); } } The compiler will warn and point out the points where recursion occurs, if it determines that the function cannot return without calling itself. Closes #17899.
