fix partial urlencoded link support
Hello Rust community.
This is my first contribution, hope is useful.
While translating in Italian the rust book https://github.com/nixxo/rust-lang-book-it I noticed that the linkchecker tool was failing reporting broken links on some pages even if the link worked properly in the browser. Upon inspection I noticed that mdbook basically urlencoded the links, but not urlencoded the heading IDs resulting in a non-identical anchor/IDs pairing that linkchecker reports as non-valid.
looking at the source code for the linkchecker tool I noticed that urlencoding was done by the `small_url_encode` function in a partial way, as the name suggests. Replacing this function with a full urlencoding fixes the issue and the links are properly reported as valid.
- added full urlencoding to properly check urlencoded anchor links against non-urlencoded heading IDs
- added tests

Port limit attributes to the new attribute parsing infrastructure
Doesn't pass tests, to be rebased on https://github.com/rust-lang/rust/pull/145792 which will solve that

compiler: Add Windows resources to rustc-main and rustc_driver
Adds Windows resources with the rust version information to rustc-main.exe and rustc_driver.dll
Invokes `rc.exe` directly, rather than using one of the crates from the ecosystem to avoid adding dependencies.
A new internal `rustc_windows_rc` crate has the common build script machinery for locating `rc.exe` and constructing the resource script
Update tracing and fix binary regression
Previous attempts (rust-lang/rust#127316, rust-lang/rust#134770) saw binary size regressions, this was root caused to <https://github.com/tokio-rs/tracing/pull/2553> which changed the behavior of the `max_level_info` feature flag to match the docs (i.e., that flag only applies for debug builds and `release_max_level_info` applies for release builds).
This change bumps the `tracing` version and sets both `max_level_info` and `release_max_level_info` when to match rustc's own `max_level_info`.
lint ImproperCTypes: refactor linting architecture (part 1)
This is the first PR in an effort to split rust-lang/rust#134697 into individually-mergeable parts.
This one focuses on properly packaging the lint and its tests, as well as properly separate the "linting" and "type-checking" code.
There is exactly one user-visible change: the safety of `Option<Box<FFISafePointee>>` is now the same in `extern` blocks and function definitions: it is safe.
r? `@tgross35` because you are already looking at the original
No changes should be visible by rustc users
This is just some architecture changes to the type checking to
facilitate FFI-safety decisions that depend on how the type is used
(the change here is not complete, there are still bits of "legacy" state
passing for this, but since this is a retconned commit, I can tell you
those bits will disappear before the end of the commit chain)
(there is at least one bit where the decision making code is weird, but
that this is because we do not want to change the lint's behaviour this
early in the chain)
move pinned version from tracing_core to tracing
This PR removes pin from `tracing-core` and moves it to `tracing`, which regressed perf in > 0.1.37 versions.
- We pick the higest common `toml` version used in the r-l/r workspace
to avoid introducing Yet Another `toml` `0.x` version, which happens
to be `0.8.23` as of the time of writing.
- We introduce a byte-buffer-to-string workaround for the `toml 0.8.*`
series that do not have the `toml 0.9.*` series's `toml::from_slice`
API yet. Not efficient, but this is not perf-critical so it's fine.
Adds Windows resources with the rust version information to rustc-main.exe and rustc_driver.dll
Sets the product description to "Rust Compiler" or "Rust Compiler (channel)" for non-stable channels
rustdoc-search: yet another stringdex optimization attempt
This one's uses a different tactic. It shouldn't significantly increase the amount of downloaded index data, but still reduces the amount of disk usage.
This one works by changing the suffix-only node representation to omit some data that's needed for checking. Since those nodes make up the bulk of the tree, it reduces the data they store, but also requires validating the match by fetching the name itself (but the names list is pretty small, and when I tried it with wordnet "indexing" it was about the same).

Remove two duplicated crates
These commits remove `toml-0.5.11` and `dirs-sys-0.4.1`. There are later versions of those same crates already in the tree. Found with `cargo tree -d`.

Refactor lint buffering to avoid requiring a giant enum
Lint buffering currently relies on a giant enum `BuiltinLintDiag` containing all the lints that might potentially get buffered. In addition to being an unwieldy enum in a central crate, this also makes `rustc_lint_defs` a build bottleneck: it depends on various types from various crates (with a steady pressure to add more), and many crates depend on it.
Having all of these variants in a separate crate also prevents detecting when a variant becomes unused, which we can do with a dedicated type defined and used in the same crate.
Refactor this to use a dyn trait, to allow using `LintDiagnostic` types directly.
Because the existing `BuiltinLintDiag` requires some additional types in order to decorate some variants, which are only available later in `rustc_lint`, use an enum `DecorateDiagCompat` to handle both the `dyn LintDiagnostic` case and the `BuiltinLintDiag` case.
---
With the infrastructure in place, use it to migrate three of the enum variants to use `LintDiagnostic` directly, as a proof of concept and to demonstrate that the net result is a reduction in code size and a removal of a boilerplate-heavy layer of indirection.
Also remove an unused `BuiltinLintDiag` variant.

This requires boxing, but all of this is already on the slow path
(emitting an error).
Because the existing `BuiltinLintDiag` requires some additional types in
order to decorate some variants, which are only available later in
`rustc_lint`, use an enum `DecorateDiagCompat` to handle both the `dyn
LintDiagnostic` case and the `BuiltinLintDiag` case.
`rustc_lint_defs` uses `rustc_hir` solely for the `Namespace` type,
which it only needs the static description from. Use the static
description directly, to eliminate the dependency on `rustc_hir`.
This reduces a long dependency chain:
- Many things depend on `rustc_errors`
- `rustc_errors` depends on `rustc_lint_defs`
- `rustc_lint_defs` depended on `rustc_hir` prior to this commit
- `rustc_hir` depends on `rustc_target`
Some crates depend on `rustc_hir` but only want `HirId` and similar id
types. `rustc_hir` is a heavy dependency, since it pulls in
`rustc_target`. Split these types out into their own crate
`rustc_hir_id`.
This allows `rustc_errors` to drop its direct dependency on `rustc_hir`.
(`rustc_errors` still depends on `rustc_hir` indirectly through
`rustc_lint_defs`; a subsequent commit will fix that.)
`rustc_errors` depends on numerous crates, solely to implement its
`IntoDiagArg` trait on types from those crates. Many crates depend on
`rustc_errors`, and it's on the critical path.
We can't swap things around to make all of those crates depend on
`rustc_errors` instead, because `rustc_errors` would end up in
dependency cycles.
Instead, move `IntoDiagArg` into `rustc_error_messages`, which has far
fewer dependencies, and then have most of these crates depend on
`rustc_error_messages`.
This allows `rustc_errors` to drop dependencies on several crates,
including the large `rustc_target`.
(This doesn't fully reduce dependency chains yet, as `rustc_errors`
still depends on `rustc_hir` which depends on `rustc_target`. That will
get fixed in a subsequent commit.)
