To not use `old_io` and `os`, which are deprecated. Since there is no more `MemoryMap` used byte parsing instead to generate the second potential error.
Hello! I noticed that the email address in AUTHORS.txt doesn't point to my home email. Could somebody merge this patch to correct it please?
Thanks very much!
This isn't really possible to test in an automatic way, since the only traits
you can negative impl are `Send` and `Sync`, and the implementors page for
those only exists in libstd.
Closes#21310
This saves a bunch of a time and will make distributions smaller, as well as
avoiding filling the implementors page with internal garbage. Turn it back on
with `--enable-compiler-docs` if you want compiler docs during development.
Crates behind the facade are only documented on nightly/dev builds (where they
can be used).

This was originally used to set up the guessing game, but that no longer
exists. This version uses `old_io`, and updating it involves talking
about `&mut` and such, which we haven't covered yet. So, for now, let's
just remove it.
Fixes#23760
with_end_to_cap is enormously expensive now that it's initializing
memory since it involves 64k allocation + memset on every call. This is
most noticable when calling read_to_end on very small readers, where the
new version if **4 orders of magnitude** faster.
BufReader also depended on with_end_to_cap so I've rewritten it in its
original form.
As a bonus, converted the buffered IO struct Debug impls to use the
debug builders.
Fixes#23815
The collections debug helpers no longer prefix output with the
collection name, in line with the current conventions for Debug
implementations. Implementations that want to preserve the current
behavior can simply add a `try!(write!(fmt, "TypeName "));` at the
beginning of the `fmt` method.

Port of pcwalton removal of `#[unsafe_destructor]` check.
Earlier commits impose rules on lifetimes that make generic destructors safe; thus we no longer need the `#[unsafe_destructor]` attribute nor its associated check.
----
So remove the check for the unsafe_destructor attribute.
And remove outdated compile-fail tests from when lifetime-parameteric dtors were disallowed/unsafe.
In addition, when one uses the attribute without the associated feature, report that the attribute is deprecated.
However, I do not think this is a breaking-change, because the attribute and feature are still currently accepted by the compiler. (After the next snapshot that has this commit, we can remove the feature itself and the attribute as well.)
----
I consider this to:
Fix#22196
(technically there is still the post snapshot work of removing the last remnants of the feature and the attribute, but the ticket can still be closed in my opinion).

curl's progress meter would otherwise interfere with sudo's password prompt.
In addition, add the -f flag to make sure 4xx status codes are treated as errors.

The Send bound is an unnecessary restriction, and though provided as a convenience, can't be removed by downstream code.
The removal of this bound is a [breaking-change] since it removes an implicit Send bound on all `E: Error` and all `Error` trait objects.
To migrate, consider if your code actually requires the Send bound and, if so, add it explicitly.

Previously a panic was generated for recursive prints due to a double-borrow of
a `RefCell`. This was solved by the second borrow's output being directed
towards the global stdout instead of the per-thread stdout (still experimental
functionality).
After this functionality was altered, however, recursive prints still deadlocked
due to the overridden `write_fmt` method which locked itself first and then
wrote all the data. This was fixed by removing the override of the `write_fmt`
method. This means that unlocked usage of `write!` on a `Stdout`/`Stderr` may be
slower due to acquiring more locks, but it's easy to make more performant with a
call to `.lock()`.
