0f6b43aa8f Remove unneeded Send bounds from std::sync::mpsc.
The requirements `T: Send` only matter if the channel crosses thread
boundaries i.e. the `Sender` or `Reciever` are sent across thread
boundaries, and which is adequately controlled by the impls of `Send`
for them. If `T` doesn't satisfy the bounds, then the types cannot cross
thread boundaries and so everything is still safe (the pair of types
collectively behave like a `Rc<RefCell<VecDeque>>`, or something of that
nature).

25d070f228 Remove unneeded Send/Sync bounds from Mutex/RwLock.
The requirements `T: Send` and `T: Send + Sync` for `Mutex` and `RwLock`
respectively only matter if those types are shared/sent across thread
boundaries, and that is adequately controlled by the impls of
`Send`/`Sync` for them. If `T` doesn't satisfy the bounds, then
the types cannot cross thread boundaries and so everything is still
safe (the two types just act like an expensive `RefCell`).

The requirement `T: Send + Sync` only matters if the `Arc` crosses
thread boundaries, and that is adequately controlled by the impls of
`Send`/`Sync` for `Arc` itself. If `T` doesn't satisfy the bounds, then
the `Arc` cannot cross thread boundaries and so everything is still
safe (`Arc` just acts like an expensive `Rc`).

Right now the rust upgrade in cargo is blocked on fixing this overflow. If a
this benchmark is run it will trigger an overflow error today:

    #[bench]
    fn foo(b: &mut test::Bencher) {}

This commit adds a check on each iteration of the loop that the maximum
multiplier (10) doesn't overflow, and if it does just return the results so far.

668c647408 Auto merge of #23137 - kmcallister:derive-sugar, r=sfackler
This is a hack, but I don't think we can do much better as long as `derive` is running at the syntax expansion phase.

If the `custom_derive` feature gate is enabled, this works with user-defined traits and syntax extensions. Without the gate, you can't use e.g. `#[derive_Clone]` directly, so this does not change the stable language.

To make this effective, we now check gated attributes both before and after macro expansion. This uncovered a number of tests that were missing feature gates.

This PR also cleans up the deriving code somewhat, and forbids some previously-meaningless attribute syntax. For this reason it's technically a

697de42f69 rollup merge of #23087: nagisa/std-undeadlock
Being a person who somehow has taken a liking to premature optimisation, my knee-jerk reaction to
locking in std handles was preamble resembling following snippet:

    let stdout = stdout();
    let lstdout = stdout.lock();
    let stdin = stdin();
    let lstdin = stdin.lock();

and then reading from the locked handle like this:

    let mut letter = [0; 1];
    lstdin.read(&mut letter).unwrap();

As it is now this code will deadlock because the `read` method attempts to lock stdout as well!

r? @alexcrichton

---

Either way, I find flushing stdout when stdin is used debatable. I believe people who write prompts should take care to flush stdout when necessary themselves.

Another idea: Would be cool if locks on std handles would be taken for a thread, rather than a handle, so given preamble (first code snippet)

    stdin.lock()

or more generally

    stdin.read(…)

worked fine. I.e. if more than a single lock are all taken inside the same thread, it would work, though not sure if our synchronisation primitives are expressive enough to make it possible.

The `std::net` primitives should be ready for use now and as a result the old
ones are now deprecated and slated for removal. Most TCP/UDP functionality is
now available through `std::net` but the `std::old_io::net::pipe` module is
removed entirely from the standard library.

Unix socket funtionality can be found in sfackler's [`unix_socket`][unix] crate
and there is currently no replacement for named pipes on Windows.

2e216896e4 Add stricter orphan rules for cross-crate impls of default traits. 2015-03-06 18:27:50 -05:00
Niko Matsakis
dbec033e29 Change the data structures for tracking defaulted traits. In the tcx, we
now have a simple set of trait def-ids. During coherence, we use a
separate table to track the default impls for any given trait so that we
can report a nice error. This fixes various bugs in the metadata
encoding that led to `ty::trait_has_default_impl` yielding the wrong
values in the cross-crate case. (In particular, default impl def-ids
were not included in the list of all impl def-ids; I debated fixing just
that, but this approach seemed cleaner overall, since we usually treat
the "defaulted" bit on traits as being a property of the trait, and now
iterating over a list of impls doesn't intermingle default impls with
normal impls.)
