Fix detecting of the 'test' attribute
Update UI test to actually check that warning is not triggered in the test code
Fix approach for detecting the test module
Add nested test case
Remove code duplication by extracting 'is_test_module_or_function' into 'clippy_utils'
Cleanup the code
Move from-iter-instead-of-collect to pedantic
Since FromIterator will become part of the prelude, this lint being
warn by default is incongruous with the libs team position on the topic.
Fixes#7213.

changelog: moved [`from_iter_instead_of_collect`] to `pedantic` group
Fix metadata code block syntax highlighting
changelog: none
Fixes code fence block in the metadata collector to change ` ``` ` or ` ```ignore` or ` ```rust,ignore` to ` ```rust`. This makes syntax highlighting work more consistently on the website.
Remove requirement of fully qualified path for disallowed_method/type
changelog: Remove the need for fully qualified paths in disallowed_method and disallowed_type
After fixing this issue in [import_rename](https://github.com/rust-lang/rust-clippy/pull/7300#discussion_r650127720) I figured I'd fix it for these two.
If this does in fact fix the **Known problems:** section I was planning to remove them from both lints after confirmation.
Vec extend to append
This PR adds a check to suggest changes of vector from
```
vec.extend(other_vec.drain(..))
```
could be written as
```
vec![].append(&mut vec![]);
```
changelog: Add vec_extend_to_append lint
issue: #7209
Don't trigger `field_reassign_with_default` in macros
Fixes#7155
Producing a good suggestion for this lint is already hard when no macros
are involved. With macros the lint message and the suggestion are just
confusing. Since both, producing a good suggestion and figuring out if
this pattern can be re-written inside a macro is nearly impossible, just
bail out.
changelog: [`field_reassign_with_default`] No longer triggers in macros

No that our reviewing queue is under control, I want to start hacking on Clippy myself again. Starting with an easy issue to get back in :)
Add disallowed_type lint, this adds a field to the conf struct
Fixes#7277
changelog: Add ``[`disallowed_type`]`` a lint that can enforce banning types specified in the config.
Make copy/copy_nonoverlapping fn's again
Make copy/copy_nonoverlapping fn's again, rather than intrinsics.
This a short-term change to address issue #84297.
It effectively reverts PRs #81167#81238 (and part of #82967), #83091, and parts of #79684.
Add FreeBSD as identifier not needing ticks
For the doc-markdown lint.
changelog: Add FreeBSD as identifier not needing ticks for ``[`doc-markdown`]`` lint.
Fix false positive on `semicolon_if_nothing_returned`
Currently the [`semicolon_if_nothing_returned`](https://rust-lang.github.io/rust-clippy/master/index.html#semicolon_if_nothing_returned) lint fires in unwanted situations where a block only spans one line. An example of this was given in #7324. This code:
```rust
use std::mem::MaybeUninit;
use std::ptr;
fn main() {
let mut s = MaybeUninit::<String>::uninit();
let _d = || unsafe { ptr::drop_in_place(s.as_mut_ptr()) };
}
```
yields the following clippy error:
```
error: consider adding a `;` to the last statement for consistent formatting
--> src/main.rs:6:26
|
6 | let _d = || unsafe { ptr::drop_in_place(s.as_mut_ptr()) };
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: add a `;` here: `ptr::drop_in_place(s.as_mut_ptr());`
|
= note: `-D clippy::semicolon-if-nothing-returned` implied by `-D clippy::pedantic`
= help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#semicolon_if_nothing_returned
```
I updated the lint to check if the statement is inside an `unsafe` block, a closure or a normal block and if the block only spans one line, in that case the lint is not emitted.
This closes#7324.
changelog: enhanced semicolon if nothing returned according to #7324.
Refactoring identity function lints
I've noticed that we have several lints that all check for identity functions and each used their own check implementation. I moved the `is_expr_identity_function` function to `clippy_utils` and adapted all lints to reuse that one function. This should make the addition of new lints like this also easier in the future.
I've also moved the `map_identity` lint into the `methods` module. It's probably the best to review this PR by checking each commit individually. And that's it, have a great day 🙃
changelog: none
fix `while_let_on_iterator` suggestion in a closure
fixes: #7249
A future improvement would be to check if the closure is being used as `FnOnce`, in which case the original suggestion would be correct.
changelog: Suggest `&mut iter` inside a closure for `while_let_on_iterator`
