2016-08-27Doc: explain why Box/Rc/Arc methods do not take selfGeorg Brandl-0/+6
This can be confusing for newcomers, especially due to the argument name "this".

2016-07-22std: Ignore tests where threads outlive mainAlex Crichton-1/+6
Long ago we discovered that threads which outlive main and then exit while the rest of the program is exiting causes Windows to hang (#20704). That's what was happening in this test so let's just not run this test any more.

2016-05-24std: Stabilize APIs for the 1.10 releaseAlex Crichton-29/+32
This commit applies the FCP decisions made by the libs team for the 1.10 cycle, including both new stabilizations and deprecations. Specifically, the list of APIs is: Stabilized: * `os::windows::fs::OpenOptionsExt::access_mode` * `os::windows::fs::OpenOptionsExt::share_mode` * `os::windows::fs::OpenOptionsExt::custom_flags` * `os::windows::fs::OpenOptionsExt::attributes` * `os::windows::fs::OpenOptionsExt::security_qos_flags` * `os::unix::fs::OpenOptionsExt::custom_flags` * `sync::Weak::new` * `Default for sync::Weak` * `panic::set_hook` * `panic::take_hook` * `panic::PanicInfo` * `panic::PanicInfo::payload` * `panic::PanicInfo::location` * `panic::Location` * `panic::Location::file` * `panic::Location::line` * `ffi::CStr::from_bytes_with_nul` * `ffi::CStr::from_bytes_with_nul_unchecked` * `ffi::FromBytesWithNulError` * `fs::Metadata::modified` * `fs::Metadata::accessed` * `fs::Metadata::created` * `sync::atomic::Atomic{Usize,Isize,Bool,Ptr}::compare_exchange` * `sync::atomic::Atomic{Usize,Isize,Bool,Ptr}::compare_exchange_weak` * `collections::{btree,hash}_map::{Occupied,Vacant,}Entry::key` * `os::unix::net::{UnixStream, UnixListener, UnixDatagram, SocketAddr}` * `SocketAddr::is_unnamed` * `SocketAddr::as_pathname` * `UnixStream::connect` * `UnixStream::pair` * `UnixStream::try_clone` * `UnixStream::local_addr` * `UnixStream::peer_addr` * `UnixStream::set_read_timeout` * `UnixStream::set_write_timeout` * `UnixStream::read_timeout` * `UnixStream::write_Timeout` * `UnixStream::set_nonblocking` * `UnixStream::take_error` * `UnixStream::shutdown` * Read/Write/RawFd impls for `UnixStream` * `UnixListener::bind` * `UnixListener::accept` * `UnixListener::try_clone` * `UnixListener::local_addr` * `UnixListener::set_nonblocking` * `UnixListener::take_error` * `UnixListener::incoming` * RawFd impls for `UnixListener` * `UnixDatagram::bind` * `UnixDatagram::unbound` * `UnixDatagram::pair` * `UnixDatagram::connect` * `UnixDatagram::try_clone` * `UnixDatagram::local_addr` * `UnixDatagram::peer_addr` * `UnixDatagram::recv_from` * `UnixDatagram::recv` * `UnixDatagram::send_to` * `UnixDatagram::send` * `UnixDatagram::set_read_timeout` * `UnixDatagram::set_write_timeout` * `UnixDatagram::read_timeout` * `UnixDatagram::write_timeout` * `UnixDatagram::set_nonblocking` * `UnixDatagram::take_error` * `UnixDatagram::shutdown` * RawFd impls for `UnixDatagram` * `{BTree,Hash}Map::values_mut` * `<[_]>::binary_search_by_key` Deprecated: * `StaticCondvar` - this, and all other static synchronization primitives below, are usable today through the lazy-static crate on stable Rust today. Additionally, we'd like the non-static versions to be directly usable in a static context one day, so they're unlikely to be the final forms of the APIs in any case. * `CONDVAR_INIT` * `StaticMutex` * `MUTEX_INIT` * `StaticRwLock` * `RWLOCK_INIT` * `iter::Peekable::is_empty` Closes #27717 Closes #27720 cc #27784 (but encode methods still exist) Closes #30014 Closes #30425 Closes #30449 Closes #31190 Closes #31399 Closes #31767 Closes #32111 Closes #32281 Closes #32312 Closes #32551 Closes #33018

2016-02-11Auto merge of #31479 - kamalmarhubi:fmt-pointer-unsized, r=alexcrichtonbors-1/+1
This allows printing pointers to unsized types with the {:p} formatting directive. The following impls are extended to unsized types: - impl<'a, T: ?Sized> Pointer for &'a T - impl<'a, T: ?Sized> Pointer for &'a mut T - impl<T: ?Sized> Pointer for *const T - impl<T: ?Sized> Pointer for *mut T - impl<T: ?Sized> fmt::Pointer for Box<T> - impl<T: ?Sized> fmt::Pointer for Rc<T> - impl<T: ?Sized> fmt::Pointer for Arc<T>

2016-02-04Fix unclear make_mut docsRichard Bradfield-3/+3
Changed the description of the `make_mut` copy-on-write behaviour in arc.rs The sentence "doesn't have one strong reference and no weak references." is a hard to understand double negative, which can be much more easily explained.
2016-01-20Fix incorrect stability annotations for arc::WeakSebastian Hahn-4/+4
This was accidentally introduced in 7e2ffc7090a70fe8c77a0e03fcec3cb1387141f2, b44ee371b8beea77aa1364460acbba14a8516559 and 36ba96ea3cfef575ddc5eea7754a1b70b50e2080.
2015-12-31Auto merge of #30593 - steveklabnik:small_rc_refactoring, r=Gankrobors-4/+5
This hairy conditional doesn't need to be so. It _does_ need to be a thin pointer, otherwise, it will fail to compile, so let's pull that out into a temporary for future readers of the source. /cc @nrc @SimonSapin @Gankro @durka , who brought this up on IRC
2015-12-30Auto merge of #30467 - shahn:master, r=brsonbors-0/+36
This adds a constructor for a Weak that can never be upgraded. These are mostly useless, but for example are required when deserializing.
2015-12-30Small refactoring to make this code more clearSteve Klabnik-4/+5
This hairy conditional doesn't need to be so. It _does_ need to be a thin pointer, otherwise, it will fail to compile, so let's pull that out into a temporary for future readers of the source. Also, after a discussion with @pnkfelix and @gankro, we don't need these null checks anymore, as zero-on-drop has been gone for a while now.

2015-11-16Auto merge of #29580 - alexbool:smart-pointer-conversion, r=alexcrichtonbors-0/+16
Sometimes when writing generic code you want to abstract over owning/pointer type so that calling code isn't restricted by one concrete owning/pointer type. This commit makes possible such code: ```rust fn i_will_work_with_arc<T: Into<Arc<MyTy>>>(t: T) { let the_arc = t.into(); // Do something } i_will_work_with_arc(MyTy::new()); i_will_work_with_arc(Box::new(MyTy::new())); let arc_that_i_already_have = Arc::new(MyTy::new()); i_will_work_with_arc(arc_that_i_already_have); ``` Please note that this patch doesn't work with DSTs. Also to mention, I made those impls stable, and I don't know whether they should be actually stable from the beginning. Please tell me if this should be feature-gated.

2015-10-30don't use drop_in_place as an intrinsicAlexis Beingessner-2/+2
2015-10-16Add `Shared` pointer and have `{Arc, Rc}` use itAndrew Paseltiner-5/+6
This change has two consequences: 1. It makes `Arc<T>` and `Rc<T>` covariant in `T`. 2. It causes the compiler to reject code that was unsound with respect to dropck. See compile-fail/issue-29106.rs for an example of code that no longer compiles. Because of this, this is a [breaking-change]. Fixes #29037. Fixes #29106.
2015-10-15Fix minor error in Arc docsMatt Brubeck-1/+1
The text says it's a vector of floats, but the code actually uses a vector of integers. The type of the Vec doesn't really matter, so I just cut it from the text.

2015-10-09Added the param-blindness attribute to `Rc` and `Arc`.Felix S. Klock II-0/+1
This was proven necessary after I added `Rc` and `Arc` to the rpass test `dropck_legal_cycles.rs`; see PR #28929.
2015-10-02std: Add AsRef/AsMut impls to Box/Rc/ArcAlex Crichton-0/+5
These common traits were left off originally by accident from these smart pointers, and a past attempt (#26008) to add them was later reverted (#26160) due to unexpected breakge (#26096) occurring. The specific breakage in worry is the meaning of this return value changed: let a: Box<Option<T>> = ...; a.as_ref() Currently this returns `Option<&T>` but after this change it will return `&Option<T>` because the `AsRef::as_ref` method shares the same name as `Option::as_ref`. A [crater report][crater] of this change, however, has shown that the fallout of this change is quite minimal. These trait implementations are "the right impls to add" to these smart pointers and would enable various generalizations such as those in #27197. [crater]: https://gist.github.com/anonymous/0ba4c3512b07641c0f99 This commit is a breaking change for the above reasons mentioned, and the mitigation strategies look like any of: Option::as_ref(&a) a.as_ref().as_ref() (*a).as_ref()
