Jason Newcomb 3e5dcba2ee Small cleanup of option_if_let_else and additional tests. 2021-08-26 11:44:36 -04:00
Jason Newcomb 8b3ca9a315 Fix option_if_let_else
* `break` and `continue` statments local to the would-be closure are allowed
* don't lint in const contexts
* don't lint when yield expressions are used
* don't lint when the captures made by the would-be closure conflict with the other branch
* don't lint when a field of a local is used when the type could be pontentially moved from
* in some cases, don't lint when scrutinee expression conflicts with the captures of the would-be closure

dswij 711c5cb6d2 Add false positive test for manual_flatten
Add a scenario where `manual_flatten` is triggered when match expression will still be used after the match in `if let`.

Jason Newcomb 9500974bdb Fix tracking of which locals would need to be captured in a closure.
* Captures by sub closures are now considered
* Copy types are correctly borrowed by reference when their value is used
* Fields are no longer automatically borrowed by value
* Bindings in `match` and `let` patterns are now checked to determine how a local is captured

Jason Newcomb 251dd30d77 Improve manual_map
In some cases check if a borrow made in the scrutinee expression would prevent creating the closure used by `map`

Jason Newcomb 4838c78ba4 Improve manual_map and map_entry
Locals which can be partially moved created within the to-be-created closure shouldn't block the use of a closure

Yuki Okushi 0af50b4d32 Rollup merge of #87385 - Aaron1011:final-enable-semi, r=petrochenkov
Make `SEMICOLON_IN_EXPRESSIONS_FROM_MACROS` warn by default

This PR makes the `SEMICOLON_IN_EXPRESSIONS_FROM_MACROS` lint warn by default.

To avoid showing a large number of un-actionable warnings to users, we only enable the lint for macros defined in the same crate. This ensures that users will be able to fix the warning by simply removing a semicolon.

In the future, I'd like to enable this lint unconditionally, and eventually make it into a hard error in a future edition. This PR is a step towards that goal.

this.

bors ac0fd99194 Auto merge of #7492 - nfejzic:improve_help, r=Manishearth
Explain flags missing in cargo check in --help

This commit closes #7389. As stated in the issue, `cargo clippy --help`
provides explanation for some flags and states that the rest are same
as in `cargo check --help`, even though some clippy specific flags
exist.

This commit extends the `cargo clippy --help` with two additional flags,
  - `cargo clippy --fix`
  - `cargo clippy --no-deps`

If there are more flags which are not present in `cargo check --help`
please bring these to my attention, I will include these aswell.
For now, I noticed only the two flags mentioned above.

changelog: `cargo clippy --help` now explains additional flags missing in `cargo check --help`.

Nadir Fejzic f7af8bf2c1 Handle --no-deps flag same as --fix flag.
As proposed in the pull request thread, there is some inconsistency in
handling the `--no-deps` flag which requires `--` before it, and
`--fix` flag which does not.
In this commit the `--no-deps` flag does not need the `--` anymore.
However, it can still be used that way: `cargo clipyy -- --no-deps`.

bors ceb7a868d3 Auto merge of #7466 - xFrednet:5393-use-more-diagnostic-items, r=flip1995
Use diagnostic items where possible

Clippy still uses a bunch of paths in places that could easily use already defined diagnostic items. This PR updates all references to such paths and also removes a bunch of them that are no longer needed after this cleanup.

Some paths are also used to construct new paths and can therefore not be removed that easily. I've added a doc comment to those instances that recommends the use of the diagnostic item where possible.

And that's it, cleaning crew signing off 🧹 🗑️
