b4443b0398 Bump macro recursion limit in release 2020-07-11 20:01:56 +02:00
Aleksey Kladov
a8891ae3ca More tight recursion limit when expanding macros in function bodies 
cc #4944
cc #5317

This doesn't fully close #4944 -- looks like we hit SO in syntax
highlighting, when we use `Semantics::expand_macro`.

Seems like we need to place expansion limit on the macro itself (store
it as a part of MacroCallId?)!

Merge #4947 
4947: Replace `impls_in_trait` query with smarter use of `CrateImplDefs` r=matklad a=jonas-schievink

`impls_in_trait` was allocating a whopping ~400 MB of RAM when running analysis-stats on r-a itself.

Remove it, instead adding a query that computes a summary `CrateImplDefs` map for all transitive dependencies. This can probably still be made more efficient, but this already reduces the peak memory usage by 25% without much performance impact on analysis-stats.

**Before**:

```
Total: 34.962107188s, 2083mb allocated 2141mb resident
   422mb ImplsForTraitQuery (deps)
   250mb CrateDefMapQueryQuery
   147mb MacroArgQuery
   140mb TraitSolveQuery (deps)
    68mb InferQueryQuery (deps)
    62mb ImplDatumQuery (deps)
```

**After**:

```
Total: 35.261100358s, 1520mb allocated 1569mb resident
   250mb CrateDefMapQueryQuery
   147mb MacroArgQuery
   144mb TraitSolveQuery (deps)
    68mb InferQueryQuery (deps)
    61mb ImplDatumQuery (deps)
    45mb BodyQuery
    45mb ImplDatumQuery
```

3c72fc0573 Anchor file-system operations to the file, and not to the source root. 
Anchoring to the SourceRoot wont' work if the path is absolute:

  #[path = "/tmp/foo.rs"]
  mod foo;

Anchoring to a file will.

However, we *should* anchor, instead of just producing an abs path.

I can imagine a situation where, for example, rust-analyzer processes
crates from different machines (or, for example, from in-memory git
branch), where the same absolute path in different crates might refer
to different files in the end!

4729: Hover actions r=matklad a=vsrs

This PR adds a `hoverActions` LSP extension and a `Go to Implementations` action as an example:
![hover_actions_impl](https://user-images.githubusercontent.com/62505555/83335732-6d9de280-a2b7-11ea-8cc3-75253d062fe0.gif)



4748: Add an `ImportMap` and use it to resolve item paths in `find_path` r=matklad a=jonas-schievink

Removes the "go faster" queries I added in https://github.com/rust-analyzer/rust-analyzer/pull/4501 and https://github.com/rust-analyzer/rust-analyzer/pull/4506. I've checked this PR on the rustc code base and the assists are still fast.

This should fix https://github.com/rust-analyzer/rust-analyzer/issues/4515.

Note that this does introduce a change in behavior: We now always refer to items defined in external crates using paths through the external crate. Previously we could also use a local path (if for example the extern crate was reexported locally), as seen in the changed test. If that is undesired I can fix that, but the test didn't say why the previous behavior would be preferable.
