sync: Move underneath libstd

2014-06-11T17:00:43+00:00

This commit is the final step in the libstd facade, #13851. The purpose of this commit is to move libsync underneath the standard library, behind the facade. This will allow core primitives like channels, queues, and atomics to all live in the same location. There were a few notable changes and a few breaking changes as part of this movement: * The `Vec` and `String` types are reexported at the top level of libcollections * The `unreachable!()` macro was copied to libcore * The `std::rt::thread` module was moved to librustrt, but it is still reexported at the same location. * The `std::comm` module was moved to libsync * The `sync::comm` module was moved under `sync::comm`, and renamed to `duplex`. It is now a private module with types/functions being reexported under `sync::comm`. This is a breaking change for any existing users of duplex streams. * All concurrent queues/deques were moved directly under libsync. They are also all marked with #![experimental] for now if they are public. * The `task_pool` and `future` modules no longer live in libsync, but rather live under `std::sync`. They will forever live at this location, but they may move to libsync if the `std::task` module moves as well. [breaking-change]

core: Finish stabilizing the `mem` module.

2014-05-24T03:55:57+00:00

* All of the *_val functions have gone from #[unstable] to #[stable] * The overwrite and zeroed functions have gone from #[unstable] to #[stable] * The uninit function is now deprecated, replaced by its stable counterpart, uninitialized [breaking-change]

use sched_yield on linux and freebsd

2014-05-15T20:50:36+00:00

pthread_yield is non-standard, while sched_yield is POSIX The Linux documentation recommends using the standard function. This is the only feature we're currently using that's present in glibc but not in musl.

core: Remove the cast module

2014-05-11T08:13:02+00:00

This commit revisits the `cast` module in libcore and libstd, and scrutinizes all functions inside of it. The result was to remove the `cast` module entirely, folding all functionality into the `mem` module. Specifically, this is the fate of each function in the `cast` module. * transmute - This function was moved to `mem`, but it is now marked as #[unstable]. This is due to planned changes to the `transmute` function and how it can be invoked (see the #[unstable] comment). For more information, see RFC 5 and #12898 * transmute_copy - This function was moved to `mem`, with clarification that is is not an error to invoke it with T/U that are different sizes, but rather that it is strongly discouraged. This function is now #[stable] * forget - This function was moved to `mem` and marked #[stable] * bump_box_refcount - This function was removed due to the deprecation of managed boxes as well as its questionable utility. * transmute_mut - This function was previously deprecated, and removed as part of this commit. * transmute_mut_unsafe - This function doesn't serve much of a purpose when it can be achieved with an `as` in safe code, so it was removed. * transmute_lifetime - This function was removed because it is likely a strong indication that code is incorrect in the first place. * transmute_mut_lifetime - This function was removed for the same reasons as `transmute_lifetime` * copy_lifetime - This function was moved to `mem`, but it is marked `#[unstable]` now due to the likelihood of being removed in the future if it is found to not be very useful. * copy_mut_lifetime - This function was also moved to `mem`, but had the same treatment as `copy_lifetime`. * copy_lifetime_vec - This function was removed because it is not used today, and its existence is not necessary with DST (copy_lifetime will suffice). In summary, the cast module was stripped down to these functions, and then the functions were moved to the `mem` module. transmute - #[unstable] transmute_copy - #[stable] forget - #[stable] copy_lifetime - #[unstable] copy_mut_lifetime - #[unstable] [breaking-change]

Register new snapshots

librustc: Remove `~EXPR`, `~TYPE`, and `~PAT` from the language, except

2014-05-07T06:12:54+00:00

for `~str`/`~[]`. Note that `~self` still remains, since I forgot to add support for `Box` before the snapshot. How to update your code: * Instead of `~EXPR`, you should write `box EXPR`. * Instead of `~TYPE`, you should write `Box`. * Instead of `~PATTERN`, you should write `box PATTERN`. [breaking-change]

Replace most ~exprs with 'box'. #11779

Add lint check for negating uint literals and variables.
