ef7587d957 Less needless_doctest_main false positives
This checks if a) the `fn main() {}` function is empty or if the doctest contains a `static`. In both cases don't lint.

Make triggering this lint less likely 📎 2019-11-29 20:47:50 +01:00

676f14baa0
Add custom ICE message that points to Clippy repo
This utilizes https://github.com/rust-lang/rust/pull/60584 by setting
our own `panic_hook` and pointing to our own issue tracker instead of
the rustc issue tracker.

This also adds a new internal lint to test the ICE message.

**Potential downsides**

* This essentially copies rustc's `report_ice` function as
  `report_clippy_ice`. I think that's how it's meant to be implemented, but
  maybe @jonas-schievink could have a look as well =)

  The downside of more-or-less copying this function is that we have to
  maintain it as well now.
  The original function can be found [here][original].
* `driver` now depends directly on `rustc` and `rustc_errors`

Closes #2734

We have a lot of false positives in this lint, so I think it makes sense
to move this to the nursery until they are resolved.

Rollup merge of #4842 - timbodeit:comparison-chain-false-positive-4827, r=flip1995
[comparison_chain] #4827 Check `core::cmp::Ord` is implemented

Only emit `comparison_chain` lint, if `cmp` is actually available on the type being compared. Don't emit lint in cases where only `PartialOrd` is implemented.

I haven't yet fully understood [Adjustments](https://doc.rust-lang.org/nightly/nightly-rustc/rustc/ty/adjustment/struct.Adjustment.html). I would appreciate, if someone could double check whether my usage of [expr_ty](https://doc.rust-lang.org/nightly/nightly-rustc/rustc/ty/struct.TypeckTables.html#method.expr_ty) in `clippy_lints/src/comparison_chain.rs:91` is correct or if there are cases where using [expr_ty_adjusted](https://doc.rust-lang.org/nightly/nightly-rustc/rustc/ty/struct.TypeckTables.html#method.expr_ty_adjusted) would lead to a different result when used with `utils::implements_trait`.

Fix Deprecated lints don't expand

### Move doc comments inside of declare_deprecated_lint macros so that they are picked up by lintlib.py

### fixes #4748

Unable to `cargo test` locally (I'm on NixOS, and keep getting errors that are similar to those #4714 might solve) but I have verified that all deprecated lints can now be expanded like other lints.

Update clippy for latest rustc changes
Specifically, this revises the clippy integration to utilize a new
callback to register its lints, as the prior editing of lint store in
Session is no longer possible.

Add lint for debug_assert_with_mut_call

closes #1526

**What does not work:**

* detecting a mut call in the format string itself, e.g. `debug_assert!(false, "{}", vec![1].pop())`
* detecting `*mut T` usage (pointer)

Fix suggestion of `explicit_counter_loop`

changelog: In the suggestion of `explicit_counter_loop`, if the `for` loop argument doesn't implement `Iterator`, then we suggest `x.into_iter().enumerate()` (or `x.iter{_mut}()` as appropriate). Also, the span of the suggestion has been corrected.

5572476a36 Add lint for debug_assert_with_mut_call
This lint will complain when you put a mutable function/method call
inside a `debug_assert` macro, because it will not be executed in
release mode, therefore it will change the execution flow, which is not
wanted.
