7336: Rename `CrateDefMap` to `DefMap` r=matklad a=jonas-schievink
I propose handling local items by computing a `DefMap` for every block expression, using the regular (early) name resolution algorithm. The result of that will be a `DefMap` that has a reference to the parent `DefMap`, which is either the one computed for the containing block expression, or the crate's root `DefMap`. Name resolution will fall back to a name in the parent `DefMap` if it cannot be resolved in the inner block.
The `DefMap`s computed for block expressions will go through a separate query that can be garbage-collected much more aggressively, since these `DefMap`s should be cheap to compute and are never part of a crate's public API.
The first step towards that is to make `CrateDefMap` not specific to crates anymore, hence this rename (if this plans sounds reasonable).

7291: Wrap remaining self/super/crate in Name{Ref} r=matklad a=Veykril
That should be the remaining special casing for `self` 🎉
Co-authored-by: Lukas Wirth <lukastw97@gmail.com>
I've noticed a bunch of "main loop too long" warnings in console when
typing in Cargo.toml. Profiling showed that the culprit is `rustc
--print cfg` call.
I moved it to the background project loading phase, where it belongs.
This highlighted a problem: we generally use single `cfg`, while it
really should be per crate.
7276: Remove map module from la-arena public API r=lnicola a=arzg
It’s unlikely that more items will be added to the module, so it’s simpler for users if `ArenaMap` is re-exported and the module made private.
This doesn’t compile for the same reason that #7275 doesn’t:
> This pull request doesn’t compile because dependencies on la-arena go through crates.io, so existing dependencies on the crate are referencing an old version. As such, this PR will only compile once a new la-arena version has been published.

7110: Deduplicate macros when offering completion r=matklad a=AdnoC
Closes https://github.com/rust-analyzer/rust-analyzer/issues/7081
When iterating over the names within the `hir_def::resolver::Scope` for a module, track what macros are in the `hir_def::item_scope::ItemScope::legacy_macros` collection for the module. When iterating over names from the prelude, do not proccess the name if it had been in the `legacy_macros` collection.
This is implemented with a `FxHashSet` in the `Scope::process_names` function that is populated when iterating over `legacy_macros` and checked when iterating over the prelude.
Alternative implementation could instead query the `legacy_macros` `FxHashMap` directly when processing names in the prelude.
Also, I'd like to add a test for this, but I'm not sure where it could be added.

Co-authored-by: Vincent Esche <regexident@gmail.com>
After we started reporting progress when running cargo check during
loading, it is possible to crash the client with two identical progress
tokens.
This points to a deeper issue: we might be running several cargo checks
concurrently, which doesn't make sense.
This commit linearizes all workspace fetches, making sure no updates are
lost.
As an additional touch, it also normalizes progress & result reporting,
to make sure they stand in sync.
6238: Split punctuation semantic highlighting up into more tags r=matklad a=Veykril
Open question would be the name of the delimiter modifiers. I chose them this was as I see them this way but from what I remember people tend to mix the names however they like. So maybe using `delimSquare`, `delimCurly`, `delimRound` would be better. That would also go well with `angle` becoming `delimAngle`?

7224: Remove unnecessary allocation when checking whether to hide argument name hint r=jhpratt a=jhpratt
The case-insensitive prefix/suffix check can be performed
character-by-character. This allows the check to be done without having
to allocate a new string. As a side effect, it's also no longer
necessary to convert the entire string to lowercase, as it's done as
needed. As the only case equality we're handling is ASCII, this
operation can be further optimized by using byte equality, rather than
character equality.

7145: Proper handling $crate Take 2 [DO NOT MERGE] r=edwin0cheng a=edwin0cheng
Similar to previous PR (#7133) , but improved the following things :
1. Instead of storing the whole `ExpansionInfo`, we store a similar but stripped version `HygieneInfo`.
2. Instread of storing the `SyntaxNode` (because every token we are interested are IDENT), we store the `TextRange` only.
3. Because of 2, we now can put it in Salsa.
4. And most important improvement: Instead of computing the whole frames every single time, we compute it recursively through salsa: (Such that in the best scenario, we only need to compute the first layer of frame)
```rust
let def_site = db.hygiene_frame(info.def.file_id);
let call_site = db.hygiene_frame(info.arg.file_id);
HygieneFrame { expansion: Some(info), local_inner, krate, call_site, def_site }
```
The overall speed compared to previous PR is much faster (65s vs 45s) :

7140: Store trait associated items in fst r=matklad a=SomeoneToIgnore
Store imported traits' associated function/methods and constants into `ImportMap.fst` and pefrorm the imports search on them.
This is a first step towards trait autoimport during completion functionality, the way I see it, after this PR, only a few major things are left to be done:
* store all traits' assoc items into fst, not only the ones in scope, as we do now. Any code pointers on how to do this are welcome 😄
* adjust a few modules in completions crate (`dot.rs`, `qualified_path.rs` at least) to query the import map, reusing the `import_assets` logic heavily
==
With the current import and autoimport implementations, it looks like for a single query, we're either interested in either associated items lookup or in all other `fst` contents lookup, but never both simultaneously.
I would rather not split `fst` in two but add another `Query` parameter to separate those, but let me know if you have any ideas.

7147: ssr: Allow replacing expressions with statements r=davidlattimore a=MarijnS95
Depends on #6587
Until that is merged, the diff is https://github.com/MarijnS95/rust-analyzer/compare/stmt..replace-expr-with-stmt
---
Now that statements can be matched and replaced (#6587) some usecases require expressions to be replaced with statements as well. This happens when something that can ambiguously be an expression or statement like `if` and loop blocks appear in the last position of a block, as trailing expression. In this case a replacement pattern of the form `if foo(){$a();}==>>$a();` will only substitute `if` blocks in the list of statements but not if they (implicitly) end up in the trailing expression, where they are not wrapped by an EXPR_STMT (but the pattern and template are, as parsing only succeeds for the `stmt ==>> stmt` case).
Instead of adding two rules that match an expression - and emit duplicate matching errors - allow the template for expressions to be a statement if it fails to parse as an expression.
---
Another gross change that does not seem to break any tests currently, but perhaps a safeguard should be added to only allow this kind of replacement in blocks by "pushing" the replacement template to the statement list and clearing the trailing expression?

This is done by adding a `ret_type` method to `hir::Function`.
I followed `assoc_fn_params` convention by creating a new `RetType` type,
that contains the actual return type accessible via a `ty` method.
6587: SSR: Support statement matching and replacing r=davidlattimore a=MarijnS95
For #3186
Hi!
This is a smaller initial patchset that came up while working on support for statement lists (and my first time working on RA 😁). It has me stuck on trailing semicolons for which I hope to receive some feedback. Matching (and replacing) `let` bindings with a trailing semicolon works fine, but trying to omit these (to make patterns more ergonomic) turns out more complex than expected.
The "optional trailing semicolon solution" implemented in this PR is ugly because `Matcher::attempt_match_token` should only consume a trailing `;` when parsing `let` bindings to prevent other code from breaking. That at the same time has a nasty side-effect of `;` ending up in the matched code: any replacements on that should include the trailing semicolon as well even if it was not in the pattern. A better example is in the tests:
3ae1649c24/crates/ssr/src/tests.rs (L178-L184)
The end result to achieve is (I guess) allowing replacement of let bindings without trailing semicolon like `let x = $a ==>> let x = 1` (but including them on both sides is still fine), and should make replacement in a macro call (where `foo!(let a = 2;)` for a `$x:stmt` is invalid syntax) possible as well. That should allow to enable/fix these tests:
3ae1649c24/crates/ssr/src/tests.rs (L201-L214)
A possible MVP of this PR might be to drop this optional `;' handling entirely and only allow an SSR pattern/template with semicolons on either side.

require expressions to be replaced with statements as well. This happens
when something that can ambiguously be an expression or statement like
`if` and loop blocks appear in the last position of a block, as trailing

foo(){$a();}==>>$a();` will only substitute `if` blocks in the list of

7115: Migrate HasSource::source to return Option r=matklad a=nick96
I've made a start on fixing #6913 based on the provided work plan, migrating `HasSource::source` to return an `Option`. The simple cases are migrated but there are a few that I'm unsure exactly how they should be handled:
- Logging the processing of functions in `AnalysisStatsCmd::run`: In verbose mode it includes the path to the module containing the function and the syntax range. I've handled this with an if-let but would it be better to blow up here with `expect`? I'm not 100% on the code paths but if we're processing a function definition then the source should exist.
I've handled `source()` in all code paths as `None` being a valid return value but are there some cases where we should just blow up? Also, all I've done is bubble up the returned `None`s, there may be some places where we can recover and still provide something.
