Fix ui test. This test checks if the compiler complains about accesing a private field before complaining (or crashing) about the private function on it not marked as stable/unstable. The interface of the internal type (sys_common's Mutex) used for this was changed. With this change, it uses another function to test for the same issue. 2020-09-24 17:11:16 +02:00			`let _ = test.comps.inner.try_lock();`
pretty: trim paths of unique symbols If a symbol name can only be imported from one place for a type, and as long as it was not glob-imported anywhere in the current crate, we can trim its printed path and print only the name. This has wide implications on error messages with types, for example, shortening `std::vec::Vec` to just `Vec`, as long as there is no other `Vec` importable anywhere. This adds a new '-Z trim-diagnostic-paths=false' option to control this feature. On the good path, with no diagnosis printed, we should try to avoid issuing this query, so we need to prevent trimmed_def_paths query on several cases. This change also relies on a previous commit that differentiates between `Debug` and `Display` on various rustc types, where the latter is trimmed and presented to the user and the former is not. 2020-09-02 10:40:56 +03:00			//~^ ERROR: field `inner` of struct `Mutex` is private
