2018-10-05Rollup merge of #54833 - abonander:issue-54441, r=petrochenkovPietro Albini-3/+1
make `Parser::parse_foreign_item()` return a foreign item or error Fixes `Parser::parse_foreign_item()` to follow the convention of `parse_trait_item()` and `parse_impl_item()` in that it *must* parse an item or return an error, and then the caller is responsible for detecting the closing delimiter. This prevents it from looping endlessly on an unexpected token in `ext/expand.rs` where it was also leaking memory by continually pushing to `Parser::expected_tokens` via `Parser::check_keyword()`. closes #54441 r? @petrochenkov cc @dtolnay
2018-10-05Auto merge of #54336 - petrochenkov:preuni, r=alexcrichtonbors-43/+30
resolve: Some refactorings in preparation for uniform paths 2.0 The main result is that in-scope resolution performed during macro expansion / import resolution is now consolidated in a single function (`fn early_resolve_ident_in_lexical_scope`), which can now be used for resolving first import segments as well when uniform paths are enabled. r? @ghost

The restrictions were introduced in https://github.com/rust-lang/rust/pull/54277 and no longer necessary now because legacy plugins are now expanded in usual left-to-right order

2018-09-27Auto merge of #52319 - tinco:issue_12590, r=pnkfelixbors-0/+1
Track whether module declarations are inline (fixes #12590) To track whether module declarations are inline I added a field `inline: bool` to `ast::Mod`. The main use case is for pretty to know whether it should render the items associated with the module, but perhaps there are use cases for this information to not be forgotten in the AST.

resolve: Implement prelude search for macro paths, implement tool attributes When identifier is macro path is resolved in scopes (i.e. the first path segment - `foo` in `foo::mac!()` or `foo!()`), scopes are searched in the same order as for non-macro paths - items in modules, extern prelude, tool prelude (see later), standard library prelude, language prelude, but with some extra shadowing restrictions (names from globs and macro expansions cannot shadow names from outer scopes). See the comment in `fn resolve_lexical_macro_path_segment` for more details. "Tool prelude" currently contains two "tool modules" `rustfmt` and `clippy`, and is searched immediately after extern prelude. This makes the [possible long-term solution](https://github.com/rust-lang/rfcs/blob/master/text/2103-tool-attributes.md#long-term-solution) for tool attributes exactly equivalent to the existing extern prelude scheme, except that `--extern=my_crate` making crate names available in scope is replaced with something like `--tool=my_tool` making tool names available in scope. The `tool_attributes` feature is still unstable and `#![feature(tool_attributes)]` now implicitly enables `#![feature(use_extern_macros)]`. `use_extern_macros` is a prerequisite for `tool_attributes`, so their stabilization will happen in the same order. If `use_extern_macros` is not enabled, then tool attributes are treated as custom attributes (this is temporary, anyway). Fixes https://github.com/rust-lang/rust/issues/52576 Fixes https://github.com/rust-lang/rust/issues/52512 Fixes https://github.com/rust-lang/rust/issues/51277 cc https://github.com/rust-lang/rust/issues/52269
2018-08-02Auto merge of #52890 - djrenren:test-visibility, r=petrochenkovbors-5/+62
Reexport tests without polluting namespaces This should fix issue #52557. Basically now we gensym a new name for the test function and reexport that. That way the test function's reexport name can't conflict because it was impossible for the test author to write it down. We then use a `use` statement to expose the original name using the original visibility.

Improve suggestion for missing fmt str in println Avoid using `concat!(fmt, "\n")` to improve the diagnostics being emitted when the first `println!()` argument isn't a formatting string literal. Fix #52347.
