2018-10-26Rollup merge of #54824 - Munksgaard:fix-49713, r=QuietMisdreavuskennytm-13/+16
Cleanup rustdoc tests with `@!has` and `@!matches` Fixes #49713 Here's a _long_ list of all the places that include `@!has`. I have marked the ones I have looked at so far. - [x] search-index.rs: fn priv_method() {} // @!has - priv_method - [x] search-index.rs: fn trait_method(&self) {} // @!has - priv_method - [x] search-index.rs: // @!has search-index.js Target - [x] short-dockblock.rs:// @!has foo/index.html '//*[@class="docblock-short"]/p/h1' 'fooo' - [x] short-dockblock.rs:// @!has foo/index.html '//*[@class="docblock-short"]/p/h2' 'mooood' - [x] keyword.rs:// @!has foo/index.html '//a/@href' 'foo/index.html' - [x] keyword.rs:// @!has foo/foo/index.html - [x] keyword.rs:// @!has-dir foo/foo - [x] issue-46380-2.rs:// @!has - '//*[@class="impl"]' 'impl PublicTrait<PrivateStruct> for PublicStruct' - [x] escape-rust-expr.rs:// @!has escape_rust_expr/constant.CONST_S.html '//pre[@class="rust const"]' '"<script>"' - [x] issue-33069.rs:// @!has - '//code' 'impl Bar for Foo' - [x] playground-empty.rs:// @!has foo/index.html '//a[@class="test-arrow"]' "Run" - [x] issue-34473.rs:// @!has - SomeTypeWithLongName - [x] issue-34473.rs:// @!has - SomeTypeWithLongName - [x] issue-34473.rs:// @!has foo/struct.SomeTypeWithLongName.html - [x] issue-29584.rs:// @!has - 'impl Bar for' - [x] hidden-line.rs:// @!has hidden_line/fn.foo.html invisible - [x] manual_impl.rs:// @!has - '//*[@class="docblock"]' 'Docs associated with the trait a_method definition.' - [x] manual_impl.rs:// @!has - '//*[@class="docblock"]' 'There is another line' - [x] manual_impl.rs:// @!has - '//*[@class="docblock"]' 'Docs associated with the trait a_method definition.' - [x] manual_impl.rs:// @!has - '//*[@class="docblock"]' 'Docs associated with the trait c_method definition.' - [x] issue-19190-2.rs:// @!has - '//*[@id="method.new"]' 'fn new() -> String' - [x] unneeded-trait-implementations-title.rs:// @!has foo/struct.Bar.html '//*[@id="implementations"]' - [x] masked.rs:// @!has 'search-index.js' 'masked_method' - [x] masked.rs:// @!has 'foo/struct.String.html' 'MaskedTrait' - [x] masked.rs:// @!has 'foo/struct.String.html' 'masked_method' - [x] masked.rs:// @!has 'foo/trait.Clone.html' 'MaskedStruct' - [x] masked.rs:// @!has 'foo/struct.MyStruct.html' 'MaskedTrait' - [x] masked.rs:// @!has 'foo/struct.MyStruct.html' 'masked_method' - [x] masked.rs:// @!has 'foo/trait.MyTrait.html' 'MaskedStruct' - [x] redirect.rs:// @!has - '//code/a' 'Qux' - [x] issue-43701.rs:// @!has implementors/core/clone/trait.Clone.js - [x] union.rs: // @!has - //pre "b: u16" - [x] prim-title.rs:// @!has - '//head/title' 'foo' - [x] empty-section.rs:// @!has - '//*[@class="synthetic-implementations"]' 'Auto Trait Implementations' - [x] traits-in-bodies-private.rs:// @!has - '//code' 'impl HiddenTrait for SomeStruct' - [x] playground-none.rs:// @!has foo/index.html '//a[@class="test-arrow"]' "Run" - [x] issue-34025.rs:// @!has 'foo/sys/index.html' - [x] issue-34025.rs:// @!has 'foo/sys/sidebar-items.js' - [x] issue-34025.rs: // @!has 'foo/sys/fn.foo.html' - [x] issue-23812.rs:// @!has - '/// Outer comment' - [x] issue-23812.rs:// @!has - '//!

2018-10-25Check for negative impls when finding auto traitsAaron Hill-0/+27
Fixes #55321 When AutoTraitFinder begins examining a type, it checks for an explicit negative impl. However, it wasn't checking for negative impls found when calling 'select' on predicates found from nested obligations. This commit makes AutoTraitFinder check for negative impls whenever it makes a call to 'select'. If a negative impl is found, it immediately bails out. Normal users of SelectioContext don't need to worry about this, since they stop as soon as an Unimplemented error is encountered. However, we add predicates to our ParamEnv when we encounter this error, so we need to handle negative impls specially (so that we don't try adding them to our ParamEnv).

2018-10-22Fix Rustdoc ICE when checking blanket implsAaron Hill-0/+31
Fixes #55001, #54744 Previously, SelectionContext would unconditionally cache the selection result for an obligation. This worked fine for most users of SelectionContext, but it caused an issue when used by Rustdoc's blanket impl finder. The issue occured when SelectionContext chose a ParamCandidate which contained inference variables. Since inference variables can change between calls to select(), it's not safe to cache the selection result - the chosen candidate might not be applicable for future results, leading to an ICE when we try to run confirmation. This commit prevents SelectionContext from caching any ParamCandidate that contains inference variables. This should always be completely safe, as trait selection should never depend on a particular result being cached. I've also added some extra debug!() statements, which I found helpful in tracking down this bug.

Fix spelling in the documentation to htmldocck.py I was reading through htmldocck.py, and decided to attempt to clean it up a little bit. Let me know if you disagree with my edits.
2018-10-11Include rustdoc tests that have been fixed by #33133Philip Munksgaard-3/+3
There was an issue (#33025) which caused these tests to not work. The issue has since been fixed in #33133, and so we can now include them.

2018-10-10Fix issue-46767 testPhilip Munksgaard-1/+2
The link that is matched against is not the same as would be generated by rustdoc. We should also check that the `foo/private` directory is not generated at all.
2018-10-10Use XPATH notation to match against flattened nodesPhilip Munksgaard-2/+2
The generated code would look like `<code>impl <a href="...">Foo</a></code>` which the plain text matcher doesn't match. But by using the XPATH notation, the nodes are flattened and we can correctly assert that `impl Foo` does not occur in the generated docs.
2018-10-05Fix empty-section.rs testPhilip Munksgaard-1/+1
The Auto Trait Implementation section is not wrapped in a `synthetic-implementations` class. In fact, it is wrapped in a `synthetic-implementations` id. However, we can generalize and completely remove the `synthetic-implementations` requirement. We just have to verify that there's no mention of "Auto Trait Implementations" anywhere.
2018-10-05Fix redirect.rs testPhilip Munksgaard-1/+2
Struct names are no longer encapsulated in `<code>` tags, which meant that the test was not correctly verifying that it wasn't being show. I've also added a check to make sure the documentation page for the redirect::Qux struct is not generated at all.
2018-10-05Fix unneeded-trait-implementations-title testPhilip Munksgaard-1/+1
The `@!has` command does not support specifying just a PATH and an XPATH. That means that the previous test searched for the literal string `//h2[@id="implementations"]` within the generated output, which obviously didn't exist. Even after adding a trait implementation, the test still passed. The correct way to check for the existence of a DOM element with the id `implementations` is to use the `@count` keyword.

Therefore, without specifying `--playground-url` as a compile-flag, the test doesn't correctly assert that `#![doc(html_playground_url = "")]` removes playground links.
2018-10-04replace escape-rust-expr test with dont-show-const-contentsPhilip Munksgaard-4/+4
The old test was supposed to check for proper html escaping when showing the contents of constants. This was changed as part of #53409. The revised test asserts that the contents of the constant is not shown as part of the generated documentation.

rustdoc: give proc-macros their own pages related to https://github.com/rust-lang/rust/issues/49553 but i don't think it'll fix it Currently, rustdoc doesn't expose proc-macros all that well. In the source crate, only their definition function is exposed, but when re-exported, they're treated as a macro! This is an awkward situation in all accounts. This PR checks functions to see whether they have any of `#[proc_macro]`, `#[proc_macro_attribute]`, or `#[proc_macro_derive]`, and exposes them as macros instead. In addition, attributes and derives are exposed differently than other macros, getting their own item-type, CSS class, and module heading. ![image](https://user-images.githubusercontent.com/5217170/46044803-6df8da00-c0e1-11e8-8c3b-25d2c3beb55c.png) Function-like proc-macros are lumped in with `macro_rules!` macros, but they get a different declaration block (i'm open to tweaking this, it's just what i thought of given how function-proc-macros operate): ![image](https://user-images.githubusercontent.com/5217170/46044828-84069a80-c0e1-11e8-9cc4-127e5477c395.png) Proc-macro attributes and derives get their own pages, with a representative declaration block. Derive macros also show off their helper attributes: ![image](https://user-images.githubusercontent.com/5217170/46094583-ef9f4500-c17f-11e8-8f71-fa0a7895c9f6.png) ![image](https://user-images.githubusercontent.com/5217170/46101529-cab3cd80-c191-11e8-857a-946897750da1.png) There's one wrinkle which this PR doesn't address, which is why i didn't mark this as fixing the linked issue. Currently, proc-macros don't expose their attributes or source span across crates, so while rustdoc knows they exist, that's about all the information it gets. This leads to an "inlined" macro that has absolutely no docs on it, and no `[src]` link to show you where it was declared. The way i got around it was to keep proc-macro re-export disabled, since we do get enough information across crates to properly link to the source page: ![image](https://user-images.githubusercontent.com/5217170/46045074-2cb4fa00-c0e2-11e8-81bc-33a8205fbd03.png) Until we can get a proc-macro's docs (and ideally also its source span) across crates, i believe this is the best way forward.

overlook overflows in rustdoc trait solving Context: The new rustdoc "auto trait" feature walks across impls and tries to run trait solving on them with a lot of unconstrained variables. This is prone to overflows. These overflows used to cause an ICE because of a caching bug (fixed in this PR). But even once that is fixed, it means that rustdoc causes an overflow rather than generating docs. This PR therefore adds a new helper that propagates the overflow error out. This requires rustdoc to then decide what to do when it encounters such an overflow: technically, an overflow represents neither "yes" nor "no", but rather a failure to make a decision. I've decided to opt on the side of treating this as "yes, implemented", since rustdoc already takes an optimistic view. This may prove to include too many items, but I *suspect* not. We could probably reduce the rate of overflows by unifying more of the parameters from the impl -- right now we only seem to consider the self type. Moreover, in the future, as we transition to Chalk, overflow errors are expected to just "go away" (in some cases, though, queries might return an ambiguous result). Fixes #52873 cc @QuietMisdreavus -- this is the stuff we were talking about earlier cc @GuillaumeGomez -- this supersedes #53687

Implement the `min_const_fn` feature gate cc @RalfJung @eddyb r? @Centril implements the feature gate for #53555 I added a hack so the `const_fn` feature gate also enables the `min_const_fn` feature gate. This ensures that nightly users of `const_fn` don't have to touch their code at all. The `min_const_fn` checks are run first, and if they succeeded, the `const_fn` checks are run additionally to ensure we didn't miss anything.
2018-08-31Auto merge of #51384 - QuietMisdreavus:extern-version, r=GuillaumeGomezbors-0/+18
rustdoc: add flag to control the html_root_url of dependencies The `--extern-html-root-url` flag in this PR allows one to override links to crates whose docs are not already available locally in the doc bundle. Docs.rs currently uses a version of this to make sure links to other crates go into that crate's docs.rs page. See the included test for intended use, but the idea is as follows: Calling rustdoc with `--extern-html-root-url crate=https://some-url.com` will cause rustdoc to override links that point to that crate to instead be replaced with a link rooted at `https://some-url.com/`. (e.g. for docs.rs this would be `https://docs.rs/crate/0.1.0` or the like.) Cheekily, rustup could use these options to redirect links to std/core/etc to instead point to locally-downloaded docs, if it so desired. Fixes https://github.com/rust-lang/rust/issues/19603
