Also rename visiting and other methods working on them.
- Rename `broken_intra_doc_links` to `rustdoc::broken_intra_doc_links`
- Ensure that the old lint names still work and give deprecation errors
- Register lints even when running doctests
Otherwise, all `rustdoc::` lints would be ignored.
- Register all existing lints as removed
This unfortunately doesn't work with `register_renamed` because tool
lints have not yet been registered when rustc is running. For similar
reasons, `check_backwards_compat` doesn't work either. Call
`register_removed` directly instead.
- Fix fallout
+ Rustdoc lints for compiler/
+ Rustdoc lints for library/
Note that this does *not* suggest `rustdoc::broken_intra_doc_links` for
`rustdoc::intra_doc_link_resolution_failure`, since there was no time
when the latter was valid.
Unfortunately, this can't currently be tested. The problem is that we
need the file to be compiled first to then be used as dependency, which
cannot be done currently unfortunately in the rustdoc test suites.
Example:
```rust
// name this file "foo.rs"
/// ```
/// let x = foo::foo();
/// ```
pub fn foo() {}
```
If you run `rustdoc --test foo.rs`, you'll get:
```
running 1 test
test foo.rs - foo (line 1) ... FAILED
failures:
---- foo.rs - foo (line 1) stdout ----
error[E0463]: can't find crate for `foo`
--> foo.rs:0:1
|
2 | extern crate foo;
| ^^^^^^^^^^^^^^^^^ can't find crate
```
If a test were possible, it would look something like
````rust
#![crate_name = "mod"]
#![crate_type = "lib"]
//! ```
//! // NOTE: requires that the literal string 'mod' appears in the doctest for
//! // the bug to appear
//! assert_eq!(1, 1);
//! ```

Deny rustc::internal lints for rustdoc and clippy
- Fix rustc::internal lints for rustdoc
- Deny internal lints only for rustdoc and clippy (previously the lints were ignored for clippy because -Zunstable-options didn't get passed)
Fixes#81007
Previously, we would fail to collect tokens in the proper place when
only builtin attributes were present. As a result, we would end up with
attribute tokens in the collected `TokenStream`, leading to duplication
when we attempted to prepend the attributes from the AST node.
We now explicitly track when token collection must be performed due to
nomterminal parsing.
The first parse is to collect whether the code contains macros, has
`main`, and uses other crates. In that pass we ignore errors as those
will be reported when the test file is actually built.
For that we need to reset errors in the `Diagnostic` otherwise when
dropping it unhandled errors will be reported as compiler bugs.
Fixes#80992
This makes it possible to pass the `Impl` directly to functions, instead
of having to pass each of the many fields one at a time. It also
simplifies matches in many cases.
When using the unstable `--persist-doctests` option,
Windows path separators were not escaped properly. Also when running
the command in a workspace, crate files can overwrite each other.
Before: `src\lib_rs_1_0\rust_out`
After: `\crate_a_src_lib_rs_1_0\rust_out`, `\crate_b_src_lib_rs_1_0\rust_out`
The main change is that `UnstableOptions::from_environment` now requires
an (optional) crate name. If the crate name is unknown (`None`), then the new feature is not available and you still have to use `RUSTC_BOOTSTRAP=1`. In practice this means the feature is only available for `--crate-name`, not for `#![crate_name]`; I'm interested in supporting the second but I'm not sure how.
Other major changes:
- Added `Session::is_nightly_build()`, which uses the `crate_name` of
the session
- Added `nightly_options::match_is_nightly_build`, a convenience method
for looking up `--crate-name` from CLI arguments.
`Session::is_nightly_build()`should be preferred where possible, since
it will take into account `#![crate_name]` (I think).
- Added `unstable_features` to `rustdoc::RenderOptions`
There is a user-facing change here: things like `RUSTC_BOOTSTRAP=0` no
longer active nightly features. In practice this shouldn't be a big
deal, since `RUSTC_BOOTSTRAP` is the opposite of stable and everyone
uses `RUSTC_BOOTSTRAP=1` anyway.
- Add tests
Check against `Cheat`, not whether nightly features are allowed.
Nightly features are always allowed on the nightly channel.
- Only call `is_nightly_build()` once within a function
- Use booleans consistently for rustc_incremental
Sessions can't be passed through threads, so `read_file` couldn't take a
session. To be consistent, also take a boolean in `write_file_header`.
- Add `parent_module` to `DocFragment`
- Require the `parent_module` of the item being inlined
- Preserve the hir_id for ExternCrates so rustdoc can find the parent module later
- Take an optional `parent_module` for `build_impl` and `merge_attrs`.
Preserve the difference between parent modules for each doc-comment.
- Support arbitrarily many re-exports in from_ast. In retrospect this is
probably not used and could be simplified to a single
`Option<(Attrs, DefId)>`.
- Don't require the parent_module for all `impl`s, just inlined items
In particular, this will be `None` whenever the attribute is not on a
re-export.
- Only store the parent_module, not the HirId
When re-exporting a re-export, the HirId is not available. Fortunately,
`collect_intra_doc_links` doesn't actually need all the info from a
HirId, just the parent module.
This modules contains the implementation of doctests, and not the
tests of rustdoc itself. This name is confusing, so let's rename it to
doctest for clarity.
