2016-05-09rustc: Implement custom panic runtimesAlex Crichton-11/+6
This commit is an implementation of [RFC 1513] which allows applications to alter the behavior of panics at compile time. A new compiler flag, `-C panic`, is added and accepts the values `unwind` or `panic`, with the default being `unwind`. This model affects how code is generated for the local crate, skipping generation of landing pads with `-C panic=abort`. [RFC 1513]: https://github.com/rust-lang/rfcs/blob/master/text/1513-less-unwinding.md Panic implementations are then provided by crates tagged with `#![panic_runtime]` and lazily required by crates with `#![needs_panic_runtime]`. The panic strategy (`-C panic` value) of the panic runtime must match the final product, and if the panic strategy is not `abort` then the entire DAG must have the same panic strategy. With the `-C panic=abort` strategy, users can expect a stable method to disable generation of landing pads, improving optimization in niche scenarios, decreasing compile time, and decreasing output binary size. With the `-C panic=unwind` strategy users can expect the existing ability to isolate failure in Rust code from the outside world. Organizationally, this commit dismantles the `sys_common::unwind` module in favor of some bits moving part of it to `libpanic_unwind` and the rest into the `panicking` module in libstd. The custom panic runtime support is pretty similar to the custom allocator support with the only major difference being how the panic runtime is injected (takes the `-C panic` flag into account).
2016-05-02std::thread docs: spawn() returns not a Thread anymoreGeorg Brandl-15/+14
Also move the "Thread type" section down a bit, since it is not so important anymore. Fixes: #33321
2016-03-25Fix unsound behaviour with null characters in thread names (issue #32475)David Henningsson-3/+18
Previously, the thread name (&str) was converted to a CString in the new thread, but outside unwind::try, causing a panic to continue into FFI. This patch changes that behaviour, so that the panic instead happens in the parent thread (where panic infrastructure is properly set up), not the new thread. This could potentially be a breaking change for architectures who don't support thread names. Signed-off-by: David Henningsson <diwic@ubuntu.com>

2016-03-12std: Clean out deprecated APIsAlex Crichton-34/+0
Removes all unstable and deprecated APIs prior to the 1.8 release. All APIs that are deprecated in the 1.8 release are sticking around for the rest of this cycle. Some notable changes are: * The `dynamic_lib` module was moved into `rustc_back` as the compiler still relies on a few bits and pieces. * The `DebugTuple` formatter now special-cases an empty struct name with only one field to append a trailing comma.

2016-02-29std: Stabilize APIs for the 1.8 releaseAlex Crichton-0/+1
This commit is the result of the FCPs ending for the 1.8 release cycle for both the libs and the lang suteams. The full list of changes are: Stabilized * `braced_empty_structs` * `augmented_assignments` * `str::encode_utf16` - renamed from `utf16_units` * `str::EncodeUtf16` - renamed from `Utf16Units` * `Ref::map` * `RefMut::map` * `ptr::drop_in_place` * `time::Instant` * `time::SystemTime` * `{Instant,SystemTime}::now` * `{Instant,SystemTime}::duration_since` - renamed from `duration_from_earlier` * `{Instant,SystemTime}::elapsed` * Various `Add`/`Sub` impls for `Time` and `SystemTime` * `SystemTimeError` * `SystemTimeError::duration` * Various impls for `SystemTimeError` * `UNIX_EPOCH` * `ops::{Add,Sub,Mul,Div,Rem,BitAnd,BitOr,BitXor,Shl,Shr}Assign` Deprecated * Scoped TLS (the `scoped_thread_local!` macro) * `Ref::filter_map` * `RefMut::filter_map` * `RwLockReadGuard::map` * `RwLockWriteGuard::map` * `Condvar::wait_timeout_with` Closes #27714 Closes #27715 Closes #27746 Closes #27748 Closes #27908 Closes #29866

2015-12-21std: Use cfg(target_thread_local) in thread_local!Alex Crichton-1/+4
This transitions the standard library's `thread_local!` macro to use the freshly-added and gated `#[cfg(target_thread_local)]` attribute. This greatly simplifies the `#[cfg]` logic in play here, but requires that the standard library expose both the OS and ELF TLS implementation modules as unstable implementation details. The implementation details were shuffled around a bit but end up generally compiling to the same thing. Closes #26581 (this supersedes the need for the option) Closes #27057 (this also starts ignoring the option)
2015-12-09std: Rename thread::catch_panic to panic::recoverAlex Crichton-18/+1
This commit is an implementation of [RFC 1236] and [RFC 1323] which rename the `thread::catch_panic` function to `panic::recover` while also replacing the `Send + 'static` bounds with a new `PanicSafe` bound.

2015-09-11std: Internalize almost all of `std::rt`Alex Crichton-3/+4
This commit does some refactoring to make almost all of the `std::rt` private. Specifically, the following items are no longer part of its API: * DEFAULT_ERROR_CODE * backtrace * unwind * args * at_exit * cleanup * heap (this is just alloc::heap) * min_stack * util The module is now tagged as `#[doc(hidden)]` as the only purpose it's serve is an entry point for the `panic!` macro via the `begin_unwind` and `begin_unwind_fmt` reexports.

2015-08-15std: Add issues to all unstable featuresAlex Crichton-64/+12
2015-08-12Remove all unstable deprecated functionalityAlex Crichton-106/+4
This commit removes all unstable and deprecated functions in the standard library. A release was recently cut (1.3) which makes this a good time for some spring cleaning of the deprecated functions.
2015-08-10Remove morestack supportAlex Crichton-14/+1
This commit removes all morestack support from the compiler which entails: * Segmented stacks are no longer emitted in codegen. * We no longer build or distribute libmorestack.a * The `stack_exhausted` lang item is no longer required The only current use of the segmented stack support in LLVM is to detect stack overflow. This is no longer really required, however, because we already have guard pages for all threads and registered signal handlers watching for a segfault on those pages (to print out a stack overflow message). Additionally, major platforms (aka Windows) already don't use morestack. This means that Rust is by default less likely to catch stack overflows because if a function takes up more than one page of stack space it won't hit the guard page. This is what the purpose of morestack was (to catch this case), but it's better served with stack probes which have more cross platform support and no runtime support necessary. Until LLVM supports this for all platform it looks like morestack isn't really buying us much. cc #16012 (still need stack probes) Closes #26458 (a drive-by fix to help diagnostics on stack overflow)

2015-07-26Remove the module-level documentation for thread::scopedKevin Ballard-34/+25
It's deprecated and unsafe, so we shouldn't be encouraging people to use it. Move it to `std::thread::scoped` instead, since it's still useful information to anyone who is using the API.

2015-06-17std: Deprecate the `scoped` featureAlex Crichton-0/+6
The `thread::scoped` function will never be stabilized as-is and the API will likely change significantly if it does, so this function is deprecated for removal.
2015-06-01std: Fix unsoundness of std::thread::ScopedKeyAlex Crichton-0/+1
Currently the compiler has no knowledge of `#[thread_local]` which forces users to take on two burdens of unsafety: * The lifetime of the borrow of a `#[thread_local]` static is **not** `'static` * Types in `static`s are required to be `Sync` The thread-local modules mostly curb these facets of unsafety by only allowing very limited scopes of borrows as well as allowing all types to be stored in a thread-local key (regardless of whether they are `Sync`) through an `unsafe impl`. Unfortunately these measures have the consequence of being able to take the address of the key itself and send it to another thread, allowing the same key to be accessed from two different threads. This is clearly unsafe, and this commit fixes this problem with the same trick used by `LocalKey`, which is to have an indirect function call to find the address of the *current thread's* thread local. This way the address of thread local keys can safely be sent among threads as their lifetime truly is `'static`. This commit will reduce the performance of cross-crate scoped thread locals as it now requires an indirect function call, but this can likely be overcome in a future commit. Closes #25894

2015-05-14Auto merge of #24920 - alexcrichton:duration, r=aturonbors-4/+40
This commit is an implementation of [RFC 1040][rfc] which is a redesign of the currently-unstable `Duration` type. The API of the type has been scaled back to be more conservative and it also no longer supports negative durations. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/1040-duration-reform.md The inner `duration` module of the `time` module has now been hidden (as `Duration` is reexported) and the feature name for this type has changed from `std_misc` to `duration`. All APIs accepting durations have also been audited to take a more flavorful feature name instead of `std_misc`. Closes #24874
