rustdoc: forward -Z options to rustc Currently rustdoc does not forward `-Z` options to rustc when building test executables. This makes impossible to use rustdoc to run test samples when crate under test is instrumented with one of sanitizers `-Zsanitizer=...`, since the final linking step will not include sanitizer runtime library. Forward `-Z` options to rustc to solve the issue. Helps with #43031.

rustdoc: warn on empty doc test Closes #60319. A doc test that only contains whitespace should result in a warning. This PR adds detection of empty doc tests to `check-code-block-syntax`, as having an invalid doc test is mutually exclusive with an empty doc test.
2019-08-24Improve Rustdoc's handling of procedural macrosAaron Hill-7/+8
Fixes #58700 Fixes #58696 Fixes #49553 Fixes #52210 This commit removes the special rustdoc handling for proc macros, as we can now retrieve their span and attributes just like any other item. A new command-line option is added to rustdoc: `--crate-type`. This takes the same options as rustc's `--crate-type` option. However, all values other than `proc-macro` are treated the same. This allows Rustdoc to enable 'proc macro mode' when handling a proc macro crate. In compiletest, a new 'rustdoc-flags' option is added. This allows us to pass in the '--proc-macro-crate' flag in the absence of Cargo. I've opened [an additional PR to Cargo](https://github.com/rust-lang/cargo/pull/7159) to support passing in this flag. These two PRS can be merged in any order - the Cargo changes will not take effect until the 'cargo' submodule is updated in this repository.

rustdoc: add option to calculate "documentation coverage" This PR adds a new flag to rustdoc, `--show-coverage`. When passed, this flag will make rustdoc count the number of items in a crate with documentation instead of generating docs. This count will be output as a table of each file in the crate, like this (when run on my crate `egg-mode`): ``` +-------------------------------------+------------+------------+------------+ | File | Documented | Total | Percentage | +-------------------------------------+------------+------------+------------+ | src/auth.rs | 16 | 16 | 100.0% | | src/common/mod.rs | 1 | 1 | 100.0% | | src/common/response.rs | 9 | 9 | 100.0% | | src/cursor.rs | 24 | 24 | 100.0% | | src/direct/fun.rs | 6 | 6 | 100.0% | | src/direct/mod.rs | 41 | 41 | 100.0% | | src/entities.rs | 50 | 50 | 100.0% | | src/error.rs | 27 | 27 | 100.0% | | src/lib.rs | 1 | 1 | 100.0% | | src/list/fun.rs | 19 | 19 | 100.0% | | src/list/mod.rs | 22 | 22 | 100.0% | | src/media/mod.rs | 27 | 27 | 100.0% | | src/place/fun.rs | 8 | 8 | 100.0% | | src/place/mod.rs | 35 | 35 | 100.0% | | src/search.rs | 26 | 26 | 100.0% | | src/service.rs | 74 | 74 | 100.0% | | src/stream/mod.rs | 49 | 49 | 100.0% | | src/tweet/fun.rs | 15 | 15 | 100.0% | | src/tweet/mod.rs | 73 | 73 | 100.0% | | src/user/fun.rs | 24 | 24 | 100.0% | | src/user/mod.rs | 87 | 87 | 100.0% | +-------------------------------------+------------+------------+------------+ | Total | 634 | 634 | 100.0% | +-------------------------------------+------------+------------+------------+ ``` Trait implementations are not counted because by default they "inherit" the docs from the trait, even though an impl can override those docs. Similarly, inherent impl blocks are not counted at all, because for the majority of cases such docs are not useful. (The usual pattern for inherent impl blocks is to throw all the methods on a type into a single impl block. Any docs you would put on that block would be better served on the type itself.) In addition, `--show-coverage` can be combined with `--document-private-items` to get the coverage counts for everything in the crate, not just public items. The coverage calculation is implemented as a late pass and two new sets of passes which strip out most of the work that rustdoc otherwise does when generating docs. The is because after the new pass is executed, rustdoc immediately closes instead of going on to generate documentation. Many examples of coverage calculations have been included as `rustdoc-ui` tests. r? @rust-lang/rustdoc

rustdoc: overhaul code block lexing errors Fixes #53919. This PR moves the reporting of code block lexing errors from rendering time to an early pass, so we can use the compiler's error reporting mechanisms. This dramatically improves the diagnostics in this situation: we now de-emphasize the lexing errors as a note under a warning that has a span and suggestion instead of just emitting errors at the top level. Additionally, this PR generalizes the markdown -> source span calculation function, which should allow other rustdoc warnings to use better spans in the future. Last, the PR makes sure that the code block is always emitted in the docs, even if it fails to highlight correctly. Of note: - The new pass unfortunately adds another pass over the docs to gather the doc blocks for syntax-checking. I wonder if this could be combined with the pass that looks for testable blocks? I'm not familiar with that code, so I don't know how feasible that is. - `pulldown_cmark` doesn't make it easy to find the spans of the code blocks, so the code that calculates the spans is a little nasty. It works for all the test cases I threw at it, but I wouldn't be surprised if an edge case would break it. Should have a thorough review. - This PR worsens the state of #56885, since those certain fatal lexing errors are now emitted before docs get generated at all.
