Closes #22698
I wasn't sure that this was appropriate for the book, but I've added this to the reference. I also noticed that one of the U+ symbols in the character literals section was missing the graves.

We were recording stability attributes applied to fields in the

actually do the checks to give errors/warnings in user crates.

Instead of allocating the same ports for ipv4 and ipv6 tests, instead draw all

port which may accidentally be interacting with other tests as the ipv-what-ness

rustdoc impl item did not include default methods for local crates, but did include them for external crates. This resulted in duplicate methods. Fix so that impl item does not include default methods for external crates.

Record the publicity of struct fields and enum variants.
The stability check checks the `PublicItems` map when giving errors if
there is a #[stable] item with a public contents that doesn't not have
its own stability. Without recording this, struct fields and enum
variants will not get errors for e.g. stable modules with unmarked
functions internally.
This is just improving the compiler's precision to give the standard
library developers more information earlier.
#[stable(feature = "rust1", since = "1.0.0")]
pub mod bar {
pub fn baz() {}
}
Without the patch it gives:
test.rs:12:5: 12:20 error: This node does not have a stability attribute
test.rs:12 pub fn baz() {}
^~~~~~~~~~~~~~~
error: aborting due to previous error
With the patch it gives:
test.rs:7:9: 7:15 error: This node does not have a stability attribute
test.rs:7 pub x: i32

test.rs:12:5: 12:20 error: This node does not have a stability attribute

If the filename for a path is `None` then we know that the creation of the
parent directory created the whole path so there's no need to retry the call to
`create_dir`.
Rollup merge of #22729 - alexcrichton:ptr-stabilization, r=aturon
Specifically, the following actions were takend:
* The `copy_memory` and `copy_nonoverlapping_memory` functions
to drop the `_memory` suffix (as it's implied by the functionality). Both
functions are now marked as `#[stable]`.
* The `set_memory` function was renamed to `write_bytes` and is now stable.
* The `zero_memory` function is now deprecated in favor of `write_bytes`
directly.
* The `Unique` pointer type is now behind its own feature gate called `unique`
to facilitate future stabilization.
Rollup merge of #22727 - alexcrichton:prep-env, r=aturon
This commit moves `std::env` away from the `std::old_io` error type as well as
the `std::old_path` module. Methods returning an error now return `io::Error`
and methods consuming or returning paths use `std::path` instead of
`std::old_path`. This commit does not yet mark these APIs as `#[stable]`.
This commit also migrates `std::old_io::TempDir` to `std::fs::TempDir` with
essentially the exact same API. This type was added to interoperate with the new
path API and has its own `tempdir` feature.
Finally, this commit reverts the deprecation of `std::os` APIs returning the old
path API types. This deprecation can come back once the entire `std::old_path`
module is deprecated.

This commit removes many unnecessary `unsafe impl` blocks as well as pushing the

for `RwLock` are a little off when reviewing #22574 and wanted to ensure that we
had our story straight on these implementations.

@dhuseby do you have this problem too ? and if yes, does this patch correct it ?
Rollup merge of #22785 - nikomatsakis:issue-21750-normalization-with-regions, r=pnkfelix
Two changes:
1. Make traits with assoc types invariant w/r/t their inputs.
2. Fully normalize parameter environments, including any region variables (which were being overlooked).
The former supports the latter, but also just seems like a reasonably good idea.

Auto merge of #22512 - nikomatsakis:issue-20300-where-clause-not-bounds, r=nikomatsakis
This is a fix for #20300 though as a side-sweep it fixes a number of stack overflows because it integrates cycle detection into the conversion process. I didn't go through and retest everything.
The tricky part here is that in some cases we have to go find the information we need from the AST -- we can't use the converted form of the where-clauses because we often have to handle something like `T::Item` *while converting the where-clauses themselves*. Since this is also not a fixed-point process we can't just try and keep trying to find the best order. So instead I modified the `AstConv` interface to allow you to request the bounds for a type parameter; we'll then do a secondary scan of the where-clauses to figure out what we need. This may create a cycle in some cases, but we have code to catch that.
Another approach that is NOT taken by this PR would be to "convert" `T::Item` into a form that does not specify what trait it's using. This then kind of defers the problem of picking the trait till later. That might be a good idea, but it would make normalization and everything else much harder, so I'm holding off on that (and hoping to find a better way for handling things like `i32::T`).
This PR also removes "most of" the `bounds` struct from `TypeParameterDef`. Still a little ways to go before `ParamBounds` can be removed entirely -- it's used for supertraits, for example (though those really ought to be converted, I think, to a call to `get_type_parameter_bounds` on `Self` from within the trait definition).
