- Remove `()` parens when referencing functions in docs.
- Change some examples to be no_run instead of ignore.
- Normalize style in examples for `OpenOptionsExt`.
- Fix typo in windows mod docs.
* Use a different loop variable, `i` was already taken. This caused
missing items in the implementors list.
* Use `.getAttribute('href')` rather than `.href` to get the relative
URL which is what it needs to actually fix the links.
Previously, any non-Unicode argument would panic rustc:
```
$ rustc $'foo\x80bar'
error: internal compiler error: unexpected panic
note: the compiler unexpectedly panicked. this is a bug.
note: we would appreciate a bug report:
https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports
thread 'rustc' panicked at 'called `Result::unwrap()` on an `Err` value:
"foo�bar"', /checkout/src/libcore/result.rs:859 note: Run with
`RUST_BACKTRACE=1` for a backtrace.
```
Now it gives a clean error:
```
$ rustc $'foo\x80bar'
error: Argument 1 is not valid Unicode: "foo�bar"
```
Maybe fixes#15890, although we still can't *compile* arbitrary file names.
Introduce a new Installer object that hold a reference to all the
configured paths for installation

Enable cross-crate incremental compilation by default.
Now that direct metadata hashing has been implemented for a while and we haven't seen any problems with it over at [rust-icci](https://travis-ci.org/rust-icci/), let's re-enable cross crate support for incremental compilation again.
r? @nikomatsakis
Unify tools building
Close#41601
Time saving for up to 10 minutes. Cargo is now only compiled once.
Downsides:
- Out of tree Cargo.lock maintenance
- Cargo.toml `[replace]` version maintenance
This is useful if parsing from stdin or a String and don't want to try and read in a module from another file. Instead we just leave a stub in the AST.
Remove interior mutability from TraitDef by turning fields into queries
This PR gets rid of anything `std::cell` in `TraitDef` by
- moving the global list of trait impls from `TraitDef` into a query,
- moving the list of trait impls relevent for some self-type from `TraitDef` into a query
- moving the specialization graph of trait impls into a query, and
- moving `TraitDef::object_safety` into a query.
I really like how querifying things not only helps with incremental compilation and on-demand, but also just plain makes the code cleaner `:)`
There are also some smaller fixes in the PR. Commits can be reviewed separately.
r? @eddyb or @nikomatsakis
This avoids double compiled Cargo. Hopefully this would speed up (extended) compilation for ~10m.
Notes: when updating Cargo submodule, the replacement version may also need to be updated.
Fix#35829 (`quote!()` does not handle `br#"…"#`)
Fix issue #35829 (syntax extension's `quote_expr!()` does not handle `b"…"` and proc_macro's `quote!()` does not handle `r#"…"#`)
* Handles `b"…"`, `br#"…"#` and `...` for `quote_expr!()`.
* Refactored the match statement to allow it to complain loudly on any unhandled token.
* Similarly, proc_macro's `quote!()` did not handle `br#"…"#` or `r#"…"#`, so this PR fixes it too.
* #42007 happens because the Session LintStore is emptied when linting.
* The Session LintStore is emptied because the checker (Early/LateContext)
wants ownership.
* The checker wants ownership because it wants to mutate the pass objects
and lint levels.
The ownership of the whole store is not essential, only the lint levels and
pass objects need to be owned. Therefore, these parts are extracted out of
the LintStore into a separate structure `LintSession`. The "check crates"
methods can operate on `&mut LintSession` instead of `&mut LintStore`.
This is a minor BREAKING CHANGE for lint writers since the `LintContext`
trait is changed: the `mut_lints` and `level_stack` methods are removed.
But no one outside of `librustc/lint/context.rs` is using these functions,
so it should be safe.
Document the `proc_macro` feature in the Unstable Book
Discusses the `proc_macro` feature flag and the features it enables:
* Implicit enable of `extern_use_macros` feature and how to import proc macros
* Error handling in proc macros (using panic messages)
* Function-like proc macros using `#[proc_macro]` and a usage example for creating and invoking
* Attribute-like proc macros using `#[proc_macro_attribute]` and a usage example for creating and invoking
