parser recovery (so that expected errors match up)
I'm opting into parser recovery in all these cases out of expediency,
not because the error messages you get with recovery enabled are
actually all that usable in all cases listed.

Change import a trait suggestion from:
help: candidate #1: use `std::io::Write`
to
help: candidate #1: `use std::io::Write`
so that the code can be copied directly.

This fixes a bug (#31845) introduced in #31105 in which lexical scopes contain items from all anonymous module ancestors, even if the path to the anonymous module includes a normal module:
```rust
fn f() {
fn g() {}
mod foo {
fn h() {
g(); // This erroneously resolves on nightly
}
}
}
```
This is a [breaking-change] on nightly but not on stable or beta.

You can now group tests into directories like `run-pass/borrowck` or `compile-fail/borrowck`. By default, all `.rs` files within any directory are considered tests: to ignore some directory, create a placeholder file called `compiletest-ignore-dir` (I had to do this for several existing directories).

This warning was introduced on Nov 28, 2015 and got into 1.6 stable, it was later requalified from a hardwired warning to a warn-by-default lint.
If this patch is landed soon enough, then `match_of_unit_variant_via_paren_dotdot` will get into 1.8 stable as a deny-by-default lint.
My intention is to turn it into a hard error after March 3, 2016, then it will hit stable at 1.9.

Now that #31461 is merged, a failing resolution can never become indeterminate or succeed, so we no longer have to keep trying to resolve failing import directives.

This commit adds functionality that allows the name resolution pass
to search for entities (traits/types/enums/structs) by name, in
order to show recommendations along with the errors.
For now, only E0405 and E0412 have suggestions attached, as per the
request in bug #21221, but it's likely other errors can also benefit
from the ability to generate suggestions.

I'm wondering if instead of a second help message, a note would be better. I let it up to reviewers.

This PR disallows non-inline modules without path annotations that are either in a block or in an inline module whose containing file is not a directory owner (fixes #29765).
This is a [breaking-change].

This PR fixes two unrelated diagnostics bugs in resolve.
First, it reports privacy errors for an import only after the import resolution is determined, fixing #31402.
Second, it expands the per-module map from block ids to anonymous modules so that it also maps module declarations ids to modules, and it uses this map to in `with_scope` to fix #31644.

fallout

|

This PR adds to `NameBinding` so it can more fully represent bindings from imports as well from items, refactors away `Target`, generalizes `ImportResolution` to a simpler type `NameResolution`, and uses a single `NameResolution`-valued map in place the existing maps `children` and `import_resolutions` (of `NameBinding`s and `ImportResolution`s, respectively), simplifying duplicate checking and name resolution.
It also unifies the `resolve_name_in_module` in `lib.rs` with its namesake in `resolve_imports.rs`, clarifying and improving the core logic (fixes #31403 and fixes #31404) while maintaining clear future-comparability with shadowable globs (i.e., never reporting that a resolution is a `Success` or is `Failing` unless this would also be knowable with shadowable globs).
Since it fixes #31403, this is technically a [breaking-change], but it is exceedingly unlikely to cause breakage in practice. The following is an example of code that would break:
```rust
mod foo {
pub mod bar {} // This defines bar in the type namespace
pub use alpha::bar; // This defines bar in the value namespace
// This should define baz in both namespaces, but it only defines baz in the type namespace.
pub use self::bar as baz;
pub fn baz() {} // This should collide with baz, but now it does not.
}
pub fn f() {}
mod alpha {
pub use self::f as bar; // Changing this to `pub fn bar() {}` causes the collision right now.
pub use super::*;
}
```
r? @nrc
|
|
A spec like `#[cfg(foo(bar))]` is not allowed as an attribute. This
makes the same spec be rejected by the compiler if passed in as a
`--cfg` argument.
Fixes #31495
