Unfortunately, the diagnostic lints are very broken and trigger much more often than they should. Correct the conditional which checks if the function call being made is to a diagnostic function so that it returns in every intended case. Signed-off-by: David Wood <david.wood@huawei.com>
The `rustc_lint_diagnostics` attribute is used by the diagnostic translation/struct migration lints to identify calls where non-translatable diagnostics or diagnostics outwith impls are being created. Any function used in creating a diagnostic should be annotated with this attribute so this commit adds the attribute to many more functions. Signed-off-by: David Wood <david.wood@huawei.com>

Just like `Box<T>`, `ThinBox<T>` owns its data on the heap, so it should implement `Send` and `Sync` when `T` does.
(Discovered in rust-lang#98571 (comment)) The change to move CStr/CString to core/alloc is currently behind feature flags as stated in rust-lang#98314
… r=oli-obk Remove a back-compat hack on lazy TAIT This PR's motivation is here: rust-lang#72614 (comment) ~~But removing a hack doesn't seem to reject the code on the issue, there're some more hacks?~~ r? ``@oli-obk``
…suggestion_highlight_lines, r=flip1995 Remove `MAX_SUGGESTION_HIGHLIGHT_LINES` After rust-lang#97798 the `MAX_SUGGESTION_HIGHLIGHT_LINES` constant doesn't really make sense since we always show full suggestions. This PR removes last usages of the constant and the constant itself. r? ``@flip1995`` (this mostly does changes in clippy)
[RFC 2011] Optimize non-consuming operators Tracking issue: rust-lang#44838 Fifth step of rust-lang#96496 The most non-invasive approach that will probably have very little to no performance impact. ## Current behaviour Captures are handled "on-the-fly", i.e., they are performed in the same place expressions are located. ```rust // `let a = 1; let b = 2; assert!(a > 1 && b < 100);` if !( { ***try capture `a` and then return `a`*** } > 1 && { ***try capture `b` and then return `b`*** } < 100 ) { panic!( ... ); } ``` As such, some overhead is likely to occur (Specially with very large chains of conditions). ## New behaviour for non-consuming operators When an operator is known to not take `self`, then it is possible to capture variables **AFTER** the condition. ```rust // `let a = 1; let b = 2; assert!(a > 1 && b < 100);` if !( a > 1 && b < 100 ) { { ***try capture `a`*** } { ***try capture `b`*** } panic!( ... ); } ``` So the possible impact on the runtime execution time will be diminished. r? ````@oli-obk````
…r=davidtwco,michaelwoerister Fix RSS reporting on macOS > NOTE: This is a duplicate of rust-lang#98164, which I closed because I borked my rustc fork Currently, `rustc_data_structures::profiling::get_resident_set_size()` always returns `None` on macOS. This is because macOS does not implement procfs used in the unix version of the function: ```rust ... else if #[cfg(unix)] { pub fn get_resident_set_size() -> Option<usize> { let field = 1; let contents = fs::read("/proc/self/statm").ok()?; let contents = String::from_utf8(contents).ok()?; let s = contents.split_whitespace().nth(field)?; let npages = s.parse::<usize>().ok()?; Some(npages * 4096) } ... ``` The proposed solution uses libproc, and more specifically `proc_pidinfo`, which has been available on macOS since 10.5 if the function signature inside libproc.h is to be believed: ```c int proc_pidinfo(int pid, int flavor, uint64_t arg, void *buffer, int buffersize) __OSX_AVAILABLE_STARTING(__MAC_10_5, __IPHONE_2_0); ```
…d-more-migration, r=compiler-errors translation: lint fix + more migration - Unfortunately, the diagnostic lints are very broken and trigger much more often than they should. This PR corrects the conditional which checks if the function call being made is to a diagnostic function so that it returns in every intended case. - The `rustc_lint_diagnostics` attribute is used by the diagnostic translation/struct migration lints to identify calls where non-translatable diagnostics or diagnostics outwith impls are being created. Any function used in creating a diagnostic should be annotated with this attribute so this PR adds the attribute to many more functions. - Port the diagnostics from the `rustc_privacy` crate and enable the lints for that crate. r? ``@compiler-errors``
…triplett Refactor iter adapters with less macros Just some code cleanup. Introduced a util `and_then_or_clear` for each of chain, flatten and fuse iter adapter impls. This reduces code nicely for flatten, but admittedly the other modules are more of a lateral move replacing macros with a function. But I think consistency across the modules and avoiding macros when possible is good.
Hermit: Fix initializing lazy locks Closes hermit-os/hermit-rs#322. The initialization function of hermit's `Condvar` is not called since rust-lang#97647 and was erroneously removed in rust-lang#97879. r? ``@m-ou-se`` CC: ``@stlankes``
Implement `Send` and `Sync` for `ThinBox<T>` Just like `Box<T>`, `ThinBox<T>` owns its data on the heap, so it should implement `Send` and `Sync` when `T` does. This extends tracking issue rust-lang#92791.
