…ttemted on a NFS mount under RHEL/CentOS 7. The syscall is supposed to return ENOSYS in most cases but when calling it on NFS it may leak through EOPNOTSUPP even though that's supposed to be handled by the kernel and not returned to userspace. Since it returns ENOSYS in some cases anyway this will trip the HAS_COPY_FILE_RANGE detection anyway, so treat EOPNOTSUPP as if it were a ENOSYS. https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/7.8_release_notes/deprecated_functionality#the_literal_copy_file_range_literal_call_has_been_disabled_on_local_file_systems_and_in_nfs https://bugzilla.redhat.com/show_bug.cgi?id=1783554
… on file size This solves several problems - race conditions where a file is truncated while copying from it. if we blindly trusted the file size this would lead to an infinite loop - proc files appearing empty to copy_file_range but not to read/write coreutils/coreutils@4b04a0c - copy_file_range returning 0 for some filesystems (overlay? bind mounts?) inside docker, again leading to an infinite loop
It is not always obvious that people could see the docs for `&` especially for beginners, it also helps learnability.
This removes the incorrect error, but doesn't show the documentation anywhere.
…r around documenting re-exports
Now this actually tests the links are generated correctly
Related to rust-lang#65354 - Pass through the replacement text to `markdown.rs` - Add some tests - Add a state machine that actually replaces the text when parsing Markdown
Often when modifying compiler code you'll miss that you've changed an API used by unit tests, since x.py check didn't previously catch that. It's also useful to have this for editing with rust-analyzer and similar tooling where editing tests previously didn't notify you of errors in test files.

- Preserve suffixes when displaying - Rename test file to match `intra-link*` - Remove unnecessary .clone()s - Improve comments and naming - Fix more bugs and add tests - Escape intra-doc link example in public documentation

…triplett Workarounds for copy_file_range issues fixes rust-lang#75387 fixes rust-lang#75446
Add a regression test for issue-72793 Adds a regression test for rust-lang#72793, which is fixed by rust-lang#75443. Note that this won't close the issue as the snippet still shows ICE with `-Zmir-opt-level=2`. But it makes sense to add a test anyway.

…ing_issues, r=steveklabnik Unstable Book: add links to tracking issues for FFI features
`impl Rc::new_cyclic` References rust-lang#75861 r? @Dylan-DPC
Link vec doc to & reference It is not always obvious that people could see the docs for `&` especially for beginners, it also helps learnability.
Remove disambiguators from intra doc link text Closes rust-lang#65354. r? @Manishearth The commits are mostly atomic, but there might be some mix between them here and there. I recommend reading 'refactor ItemLink' and 'refactor RenderedLink' on their own though, lots of churn without any logic changes.
…uillaumeGomez Fix intra-doc links on pub re-exports Partial fix for rust-lang#76073 - This removes the incorrect error, but doesn't show the documentation anywhere. r? @GuillaumeGomez
…odrAus Use Arc::clone and Rc::clone in documentation This PR replaces uses of `x.clone()` by `Rc::clone(&x)` (or `Arc::clone(&x)`) to better match the documentation for those types. @rustbot modify labels: T-doc
rename MaybeUninit slice methods The `first` methods conceptually point to the whole slice, not just its first element, so rename them to be consistent with the raw ptr methods on ref-slices. Also, do the equivalent of rust-lang#76047 for the slice reference getters, and make them part of rust-lang#63569 (so far they somehow had no tracking issue). * first_ptr -> slice_as_ptr * first_ptr_mut -> slice_as_mut_ptr * slice_get_ref -> slice_assume_init_ref * slice_get_mut -> slice_assume_init_mut
