4d60841205 Auto merge of #3596 - xfix:remove-crate-from-paths, r=flip1995
Remove crate:: prefixes from crate paths

This is somewhat misleading, as those are actually external crates,
and don't need a crate:: prefix.

Downgrade large_digit_groups to pedantic
I believe if the user already decided to put underscores in their
literal, Clippy should be willing to believe that they put a number of
underscores that they felt was readable.

Downgrade unsafe_vector_initialization to restriction
This lint looks for:

    let mut vec = Vec::with_capacity(len);
    vec.set_len(len);

The suggested replacement is `vec![0; len]`.

This is far too opinionated to be a deny-by-default lint because the performance
characteristics of the suggested replacement are totally different.

I am not convinced that this lint has value beyond what deny(unsafe_code) gives
you. Unsafe code is unsafe but please don't deny-by-default lint it if that's
the only reason.

e0ccc9d9af Add slow zero-filled vector initialization lint
Add lint to detect slow zero-filled vector initialization. It detects
when a vector is zero-filled with extended with `repeat(0).take(len)`
or `resize(len, 0)`.
This zero-fillings are usually slower than simply using `vec![0; len]`.

Downgrade needless_pass_by_value to allow by default
I noticed that I suppress this lint in many of my projects.

https://github.com/search?q=needless_pass_by_value+user%3Adtolnay&type=Code
https://github.com/search?q=needless_pass_by_value+user%3Aserde-rs&type=Code

Upon further inspection, this lint has a *long* history of false
positives (and several remaining).

Generally I feel that this lint is the definition of pedantic and should
not be linted by default.

    #[derive(Debug)]
    enum How {
        ThisWay,
        ThatWay,
    }

    // Are we really better off forcing the call sites to write f(&_)...?
    fn f(how: How) {
        println!("You want to do it {:?}", how);
    }

    fn main() {
        f(How::ThatWay);
    }

RIIR update lints: Add check mode (update_lints.py rewrite complete)
This finishes up the rewrite of `update_lints.py` in Rust. More
specifically, this

* adds the `--check` flag and handling to clippy_dev
* tracks file changes over the different calls to `replace_region_in_file`
* only writes changes to files if the `--check` flag is *not* used
* runs `./util/dev update_lints --check` on CI instead of the old script
* replaces usage of the `update_lints.py` script with an error

`./util/dev update_lints` behaves 99% the same as the python script.
The only difference that I'm aware of is an ordering change to
`clippy_lints/src/lib.rs` because underscores seem to be sorted
differently in Rust and in Python.

0ad5b9b9e0 Merge #3388
3388: RIIR update lints: Generate deprecated lints r=phansch a=phansch

The update script now also generates the 'register_removed' section in
`clippy_lints/src/lib.rs`.

Also, instead of using `let mut store ...`, I added a new identifier
line so that the replacement will continue to work in case `let mut
store ...` ever changes.
