5693: Fix no inlay hints / unresolved tokens until manual edit to refresh r=jonas-schievink a=Veetaha
Fixes https://github.com/rust-analyzer/rust-analyzer/issues/5349
Now we return ContentModified during the workspace loading. This signifies the language
client to retry the operation (i.e. the client will
continue polling the server while it returns ContentModified).
I believe that there might be cases of overly big projects where the backoff
logic we have setup in `sendRequestWithRetry` (which we use for inlay hints)
might bail too early (currently the largest retry standby time is 10 seconds).
However, I've tried on one of my project with 500+ dependencies and it is still enough.
Here are the examples before/after the change (the gifs are quite lengthy because they show testing rather large cargo workspace).
<details>
<summary>Before</summary>
Here you can see that the client receives empty array of inlay hints and does nothing more.
Same applies to semantic tokens. The client receives unresolved tokens and does nothing more.
The user needs to do a manual edit to refresh the editor.
</details>
<details>
<summary>After</summary>
Here the server returns ContentModified, so the client periodically retries the requests and eventually receives the wellformed response.

5414: Fix test code lens r=jonas-schievink a=avrong
Closes#5217
The implementation is quite similar to #4821. Maybe we should somehow deal with duplicated code.
Also, both of these requests introduce some unclear behavior. I'm not sure how to process this, therefore asking for advice. Examples are below.

5684: Semantic highlighting for unsafe union field access r=jonas-schievink a=Nashenas88
This change adds support for unions in inference and lowering, then extends on that to add the unsafe semantic modifier on field access only. The `is_possibly_unsafe` function in `syntax_highlighting.rs` could be extended to support fns and static muts so that their definitions are not highlighted as unsafe, but only their usage.
Also, each commit of this PR updates the tests. By reviewing the files by commit, it's easy to see how the changes in the code affected the tests.

5679: Account for static mut in missing unsafe diagnostic r=jonas-schievink a=Nashenas88
Accessing or modifying a static mut is an unsafe operation. The "missing unsafe" diagnostic now tracks this.

5678: Static mut unsafe semantic highlighting r=jonas-schievink a=Nashenas88
This marks static mutable names as unsafe, since accessing or modifying a static mut is an unsafe operation.

5526: Handle semantic token deltas r=kjeremy a=kjeremy
This basically takes the naive approach where we always compute the tokens but save space sending over the wire which apparently solves some GC problems with vscode.
This is waiting for https://github.com/gluon-lang/lsp-types/pull/174 to be merged. I am also unsure of the best way to stash the tokens into `DocumentData` in a safe manner.

5639: SSR: Allow `self` in patterns. r=jonas-schievink a=davidlattimore
It's now consistent with other variables in that if the pattern references self, only the `self` in scope where the rule is invoked will be accepted. Since `self` doesn't work the same as other paths, this is implemented by restricting the search to just the current function. Prior to this change (since path resolution was implemented), having self in a pattern would just result in no matches.

5664: Fix renamed self module. r=jonas-schievink a=Nashenas88
Fixes#5663

`current_dir` and relative paths to executables works differently on
unix and windows (unix behavior does not make sense), see:
17e30e83a1/src/lib.rs (L295-L324)
The original motivation to set cwd was to make rustfmt read the
correct rustfmt.toml, but that was future proofing, rather than a bug
fix.
So, let's just remove this and see if breaks or fixes more use-cases.
If support for per-file config is needed, we could use `--config-path`
flag.
5658: do not add to `pub use` in assists that insert a use statement r=jonas-schievink a=jbr
closes#5657 , see issue for rationale
Initially I wrote a version of this that changed the signature of `insert_use_statement` to take an `Option<VisibilityKind>` and only add to use statements with the same visibility, but that didn't make sense for any of the current uses of `insert_use_statement` (they all expected private visibility).

Prior to this change (since path resolution was implemented), having

This fixes matching of things like `HashMap::default()` by resolving
`HashMap` instead of `default` (which resolves to `Default::default`).
Same for associated constants and types that are part of a trait
implementation.
However, we still don't support matching calls to trait methods.
Note that `for` type is rust-analyzer's own invention.
Both the reference and syn allow `for` only for fnptr types, and we
allow them everywhere. This needs to be checked with respect to type
bounds grammar...
The TypeRef name comes from IntelliJ days, where you often have both
type *syntax* as well as *semantical* representation of types in
scope. And naming both Type is confusing.
In rust-analyzer however, we use ast types as `ast::Type`, and have
many more semantic counterparts to ast types, so avoiding name clash
here is just confusing.
5596: Add checkOnSave.noDefaultFeatures and correct, how we handle some cargo flags. r=clemenswasser a=clemenswasser
This PR adds the `rust-analyzer.checkOnSave.noDefaultFeatures` option
and fixes the handling of `cargo.allFeatures`, `cargo.noDefaultFeatures` and `cargo.features`.
Fixes: #5550
Co-authored-by: Clemens Wasser <clemens.wasser@gmail.com>
This commit fixes the handling of user-defined configuration
of some cargo options. Previously you could either specify
`--all-features`, `--no-default-features` or `--features`.
Now you can specify either `--all-features` or `--no-default-features`
and `--features`. This commit also corrects the `--features`
command-line argument creation inside of `load_extern_resources`.
5567: SSR: Wrap placeholder expansions in parenthesis when necessary r=matklad a=davidlattimore
e.g. `foo($a) ==> $a.to_string()` should produce `(1 + 2).to_string()` not `1 + 2.to_string()`
We don't yet try to determine if the whole replacement needs to be wrapped in parenthesis. That's harder and I think perhaps less often an issue.

5554: Fix remove_dbg r=matklad a=petr-tik
Closes#5129
Addresses two issues:
- keep the parens from dbg!() in case the call is chained or there is
semantic difference if parens are excluded
- Exclude the semicolon after the dbg!(); by checking if it was
accidentally included in the macro_call
investigated, but decided against:
fix ast::MacroCall extraction to never include semicolons at the end -
this logic lives in rowan.
Defensively shorten the macro_range if there is a semicolon token.
Deleted unneccessary temp variable macro_args
Renamed macro_content to "paste_instead_of_dbg", because it isn't a
simple extraction of text inside dbg!() anymore

replaced match with let-if variable assignment
removed the unnecessary semicolon_on_end variable
converted all code and expected test variables to raw strings
and inlined them in asserts
The primary advantage of ungrammar is that it (eventually) allows one
to describe concrete syntax tree structure -- with alternatives and
specific sequence of tokens & nodes.
That should be re-usable for:
* generate `make` calls
* Rust reference
* Hypothetical parser's evented API
We loose doc comments for the time being unfortunately. I don't think
we should add support for doc comments to ungrammar -- they'll make
grammar file hard to read. We might supply docs as out-of band info,
or maybe just via a reference, but we'll think about that once things
are no longer in flux
5564: SSR: Restrict to current selection if any r=davidlattimore a=davidlattimore

5565: SSR: Don't mix non-path-based rules with path-based r=matklad a=davidlattimore
If any rules contain paths, then we reject any rules that don't contain paths. Allowing a mix leads to strange semantics, since the path-based rules only match things where the path refers to semantically the same thing, whereas the non-path-based rules could match anything. Specifically, if we have a rule like `foo ==>> bar` we only want to match the `foo` that is in the current scope, not any `foo`. However "foo" can be parsed as a pattern (BIND_PAT -> NAME -> IDENT). Allowing such a rule through would result in renaming everything called `foo` to `bar`. It'd also be slow, since without a path, we'd have to use the slow-scan search mechanism.

It seems that Semantics::scope, if given a statement node, won't resolve
locals that were defined in the current scope, only in parent scopes.
Not sure if this is intended / expected behavior, but we work around it
for now by finding another nearby node to use as the scope (e.g. the
expression inside the EXPR_STMT).
5520: Add DocumentData to represent in-memory document with LSP info r=matklad a=kjeremy
At the moment this only holds document version information but in the near-future it will hold other things like semantic token delta info.
