|\ \ | |/ |/| | | | | | | | | | | | | | | | | | | 6307: Add whitelist of safe intrinsics r=frazar a=frazar This PR should fix #5996, where intrinsic operations where all marked as unsafe. I'm rather new to this codebase, so I might be doing something *very* wrong. Please forgive me! In particular, I'm not sure how to "check that we are in extern `rust-intrinsics`" as mentioned [in this comment](https://github.com/rust-analyzer/rust-analyzer/issues/5996#issuecomment-709234802).

| | | | | | | | | | | | | | | | Declaration names sounds like a name of declaration -- something you can use for analysis. It empathically isn't, and is just a label displayed in various UI. It's important not to confuse the two, least we accidentally mix semantics with UI (I believe, there's already a case of this in the FamousDefs at least).

After a third try, it finally works. Boy, it appeared tougher than it seemed. Initially I thought like "Ha, `rustc` already tells us where idents are named incorrectly. It shouldn't be that hard, should it?". Well, the problems with the information provided by `rustc` appeared shortly: - `rustc` warnings are `flycheck` warnings, which are slightly aside from our diagnostics with fixes. When we map flycheck diagnostic to LSP, we can convert it into a fix, but only if it's marked as `Applicability::MachineApplicable`. Name case fix is marked `Applicability::MaybeIncorrect`, and for a reason: it only suggest to rename symbol under cursor, without tracking any references. - Warning spawned by `rustc` are identified by string labels rather than enum. It means that if one day the diagnostic will be renamed in `rustc`, `rust-analyzer` code will still compile, but won't find the required diagnostic by name anymore. If by chance this will happen when some unlucky guy will decide to create their first pull request, they'll be confused by suddenly failing tests (likely) not related to their changes. - Even if we'll try to build fixes atop of `rustc` warnings, we'll have to do it in the `rust_analyzer::diagnostics::to_proto` module, which is far less convenient for that matter than `ide` crate. That's why I decided that it's worth a separate `rust-analyzer` diagnostic, which will implement `DiagnosticWithFix` trait. After that, I discovered that currently `hir_ty::diagnostics` only check `DefWithBody` types, like function bodies. I had to add support for diagnostics which look at any `ModuleDef`. And of course, since I'd added a lot of new functionality, it required extensive testing. That explains why the diff is so big for a (looking) relatively small feature. I hope that this PR doesn't only add a small feature, but also creates a base for building another features. ## Example: ![case_quick_fix](https://user-images.githubusercontent.com/12111581/95008475-e07ee780-0622-11eb-9978-62a9ea0e7782.gif) P.S.

| |/ | | | | | | | | | | | | | | | | Currently a method only has defaultness if it is a provided trait method, but this will change when specialisation is available and may need to become a concept known to hir. I opted to go for a 'fewest changes' approach given specialisation is still under development.

|\ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 6033: Make name resolution resolve proc macros instead of relying purely on the build system r=matklad a=jonas-schievink This makes name resolution look at proc-macro declaration attributes like `#[proc_macro_derive]` and defines the right proc macro in the macro namespace, fixing unresolved custom derives like `thiserror::Error` (which can cause false positives, now that we emit diagnostics for unresolved imports). This works even when proc-macro support is turned off, in which case we fall back to a dummy expander that always returns an error. IMO this is the right way to handle at least the name resolution part of proc. macros, while the *expansion* itself should rely on the build system to build and provide the macro DLL. It does mean that they may go out of sync, but we can provide diagnostics if that happens (something like "could not find macro X in crate Y – ensure that all files of crate Y are saved"). I think it is valuable to be able to reason about proc macros even when we can't expand them, since proc macro expansion can break between Rust releases or users might not want to turn it on for performance reasons. It allows us to provide better diagnostics on any proc macro invocation we're not expanding (like a weak warning that informs the user that proc macro support is turned off, or that it has been disabled because the server crashed).

|\ \ | |/ |/| | | | | | | | | | | | | | | 6016: Emit diagnostics for unresolved imports and extern crates r=jonas-schievink a=jonas-schievink AFAIK, we don't have any major bugs in name resolution that would cause a lot of false positives here (except procedural attribute macro support and some rare issues around `#[path]` on module files), so these are *not* marked as experimental diagnostics right now. I noticed that diagnostics in a file sometimes don't get displayed after opening, but require some edit to be performed. This seems like a preexisting issue though.
