If the remote process is terminated by a signal, make `remote-test-client` exit with the code `128 + <signal-number>` instead of always `3`. This follows common practice among tools such as bash [^1]: > When a command terminates on a fatal signal whose number is N, Bash uses the > value 128+N as the exit status. It also allows us to differentiate between `run-pass` and `run-crash` ui tests without special case code in compiletest for that when `remote-test-client` is used.

Changelog: https://github.com/rust-lang/mdBook/blob/master/CHANGELOG.md#mdbook-0452 This primarily picks up a few fixes.

Implements https://www.github.com/rust-lang/rust/issues/141358. This has 2 primary benefits: 1. For rustdoc-json consumers, they no longer need to parse strings of attributes, but it's there in a structured and normalized way. 2. For rustc contributors, the output of HIR pretty printing is no longer a versioned thing in the output. People can work on rust-lang#131229 without needing to bump `FORMAT_VERSION`. (Over time, as the attribute refractor continues, I expect we'll add new things to `rustdoc_json_types::Attribute`. But this can be done separately to the rustc changes).
…istime, r=GuillaumeGomez rustdoc-json: Structured attributes Implements and closes rust-lang#141358. This has 2 primary benefits. 1. For rustdoc-json consumers, they no longer need to parse strings of attributes, but it's there in a structured and normalized way. CC ``@obi1kenobi`` 2. For rustc conributors, the output of HIR pretty printing is no longer a versioned thing in the output. People can work on rust-lang#131229 without needing to bump `FORMAT_VERSION`. CC ``@jdonszelmann`` ``@JonathanBrouwer.`` (Over time, as the attribute refractor continues, I expect we'll add new things to `rustdoc_json_types::Attribute`. But this can be done separately to the rustc changes). Todo before being mergable: - [x] Update test assertions. - [x] Fix modeling of `#[repr]`. - [ ] ~~Add tests of `#[doc(hidden)]` in `Item::attrs` (probably in a seperate PR).~~ I'm gonna punt this to a future PR - [x] Documentation.
…bzol tidy: check for invalid file names Check for file names added to git with: - non-UTF8 filenames (this would fail "fmt check" with a decoding error for the moment, but maybe we should not count on it as it is an accidental failure) - control characters (such as "\n" or "\r" in file names) - ":" (which is a special character on Windows, made rust-lang#142936 fail in bors while it could have be caught earlier) It only checks files known by git as a developer might want to have "strange" file names alongside their local repository as long as they don't check them in. r? jieyouxu as he stumbled upon such a file in rust-lang#142936
Add tracing to `InterpCx::fn_abi_of_instance/fn_abi_of_fn_ptr` This PR adds tracing to the `InterpCx::fn_abi_of_instance`/`::fn_abi_of_fn_ptr` functions by shadowing `FnAbiOf`'s trait methods with inherent methods on `InterpCx`, like done in rust-lang#142721. The reason why I am targeting these two functions is because they are used for Miri interpretation, and they make a `layout_of` query down the line without passing through the `layout_of` that was traced in rust-lang#142721. There are other places where `layout_of` is called without being traced (see the analysis below), but that's because the `Machine` used there is not `MiriMachine` but rather `CompileTimeMachine` which does not implement `enter_trace_span()`. But after discussing with ``````@RalfJung`````` we agreed that the const-eval part should not be traced together with Miri, that's why I am ignoring the other places where `layout_of` is called. r? ``````@RalfJung`````` <details><summary>Analysis of the places where <code>layout_of</code> is called</summary> I did some analysis for rust-lang#142721 (comment), and these are all the places where the query `tcx.layout_of` is called (directly or indirectly) outside of a traced `InterpCx::layout_of` while a program is being interpreted by Miri: ``` adjust_for_rust_scalar at ./compiler/rustc_ty_utils/src/abi.rs:302:35 {closure#2} at ./compiler/rustc_ty_utils/src/abi.rs:522:25 eval_body_using_ecx<> at ./compiler/rustc_const_eval/src/const_eval/eval_queries.rs:49:22 {closure#1}<> at ./compiler/rustc_const_eval/src/interpret/operand.rs:851:76 {closure#0}<> at ./compiler/rustc_const_eval/src/interpret/stack.rs:612:18 size_and_align at ./compiler/rustc_middle/src/mir/interpret/mod.rs:387:38 ``` I got these by: - patching rustc with this patch that adds a span to the `layout_of` query which prints the backtrace: [layout_of_other_places.diff.txt](https://github.com/user-attachments/files/21235523/layout_of_other_places.diff.txt) - adding this to my bootstrap.toml to have debug symbols inside the Miri binary: `rust.debuginfo-level = "line-tables-only"` and also `build.tool.miri.features = ["tracing"]` - obtaining a trace file with `MIRI_TRACING=1 ./x.py run miri --stage 1 --warnings warn --args src/tools/miri/tests/pass/hello.rs` (note: maybe using a file different than "src/tools/miri/tests/pass/hello.rs" would lead to more places where layout_of is called?) - running this query in Perfetto to select all `layout_of` spans that have as a direct parent a span named "frame" (as opposed to the parent being `InterpCx::layout_of`) and extract their backtrace: `select args.string_value from slice left join args on slice.arg_set_id = args.id where slice.name = "tcx.layout_of" and slice.parent_id in (select slice2.id from slice as slice2 where slice2.name = "frame") group by args.string_value` - exporting the data as `.tsv` and processing that file through this Python script. It finds the first path in the backtraces where "layout" isn't mentioned, which imo is a good heuristic to not consider `layout_of` wrappers/friends as call places, but rather go down the backtrace until an actual call place is reached.
