This commit makes the JSON emitter use `-Z terminal-width` in the "rendered" field of the JSON output. Signed-off-by: David Wood <david@davidtw.co>
Normally, we encode a `Span` that references a foreign `SourceFile` by encoding information about the foreign crate. When we decode this `Span`, we lookup the foreign crate in order to decode the `SourceFile`. However, this approach does not work for proc-macro crates. When we load a proc-macro crate, we do not deserialzie any of its dependencies (since a proc-macro crate can only export proc-macros). This means that we cannot serialize a reference to an upstream crate, since the associated metadata will not be available when we try to deserialize it. This commit modifies foreign span handling so that we treat all foreign `SourceFile`s as local `SourceFile`s when serializing a proc-macro. All `SourceFile`s will be stored into the metadata of a proc-macro crate, allowing us to cotinue to deserialize a proc-macro crate without needing to load any of its dependencies. Since the number of foreign `SourceFile`s that we load during a compilation session may be very large, we only serialize a `SourceFile` if we have also serialized a `Span` which requires it.
`fs::DirEntry::metadata` doesn't traverse symlinks. It is not immediately clear what to do if you do want to traverse symlinks. This change adds links to the two other `metadata` functions that will follow symlinks.
Added io forwarding methods to the stdio structs Added methods to forward the `io::Read` and `io::Write` methods of the myriad wrapper structs in `stdio.rs` to their underlying readers / writers. This is especially important for the structs on the outside of a locking boundary, to ensure that the lock isn't being dropped and re-acquired in a loop.
…ewjasper MIR sanity check: validate types on assignment This expands the MIR validation added by @jonas-schievink in rust-lang#72093 to also check that on an assignment, the types of both sides match. Cc @eddyb @oli-obk
…Amanieu Add documentation to point to `File::open` or `OpenOptions::open` instead of `is_file` to check read/write possibility Fixes rust-lang#64170. This adds documentation to point user towards `!is_dir` instead of `is_file` when all they want to is read from a source. I ran `rg "fn is_file\("` to find all `is_file` methods, I hope I did not miss one.
Adds a clearer message for when the async keyword is missing from a f… …unction This is a somewhat simple fix for rust-lang#66731. Under the current version of Rust, if a user has a rust file that looks like this: ```rust fn boo (){} async fn foo() { boo().await; } fn main() { } ``` And they attempt to run it, they will receive an error message that looks like this: ```bash error: incorrect use of `await` --> test.rs:4:14 | 4 | boo.await(); | ^^ help: `await` is not a method call, remove the parentheses error[E0277]: the trait bound `fn() {boo}: std::future::Future` is not satisfied --> test.rs:4:5 | 4 | boo.await(); | ^^^^^^^^^ the trait `std::future::Future` is not implemented for `fn() {boo}` error: aborting due to 2 previous errors For more information about this error, try `rustc --explain E0277`. ``` This is not very clear. With the changes made in this PR, when a user compiles and runs that same rust code, they will receive an error message that looks like this: ```bash error[E0277]: `()` is not a future. --> test.rs:4:5 | 4 | boo().await; | ^^^^^^^^^^^ `()` is not a future | = help: the trait `std::future::Future` is not implemented for `()` = note: required by `std::future::Future::poll` ``` In the future, I think we should make this error message even clearer, perhaps through a solution like the one described in [this comment](rust-lang#66731 (comment)). However, as that potentially involves a major change proposal, I would rather get this change in now and make the error message a little clearer while an MCP is drafted and discussed.

…an, r=petrochenkov Serialize all foreign `SourceFile`s into proc-macro crate metadata Normally, we encode a `Span` that references a foreign `SourceFile` by encoding information about the foreign crate.

replace more `DefId`s with `LocalDefId` part of rust-lang#70853
fix typo in self-profile.md
Forward Hash::write_iN to Hash::write_uN The `Hasher::write_iN()` methods should forward to `Hasher::write_uN()`, because some Hasher implementations implement only the `write_uN()` variants, with the expectation that `write_iN()` will use the same implementation. Most notably, this is the case for the [FxHasher](https://github.com/rust-lang/rustc-hash/blob/5e09ea0a1c7ab7e4f9e27771f5a0e5a36c58d1bb/src/lib.rs#L111) used by rustc itself. This used to be the case previously, but was broken in rust-lang#59982. As the PR description makes no mention of this particular change, I assume it was unintentional. In a local test, this mitigates the regression from rust-lang#73526 on at least one test-case (cc @cuviper), because we're no longer at the mercy of `FxHasher::write()` getting inlined to get reasonable performance.
