2016-04-12std: Stabilize APIs for the 1.9 releaseAlex Crichton-12/+5
This commit applies all stabilizations, renamings, and deprecations that the library team has decided on for the upcoming 1.9 release. All tracking issues have gone through a cycle-long "final comment period" and the specific APIs stabilized/deprecated are: Stable * `std::panic` * `std::panic::catch_unwind` (renamed from `recover`) * `std::panic::resume_unwind` (renamed from `propagate`) * `std::panic::AssertUnwindSafe` (renamed from `AssertRecoverSafe`) * `std::panic::UnwindSafe` (renamed from `RecoverSafe`) * `str::is_char_boundary` * `<*const T>::as_ref` * `<*mut T>::as_ref` * `<*mut T>::as_mut` * `AsciiExt::make_ascii_uppercase` * `AsciiExt::make_ascii_lowercase` * `char::decode_utf16` * `char::DecodeUtf16` * `char::DecodeUtf16Error` * `char::DecodeUtf16Error::unpaired_surrogate` * `BTreeSet::take` * `BTreeSet::replace` * `BTreeSet::get` * `HashSet::take` * `HashSet::replace` * `HashSet::get` * `OsString::with_capacity` * `OsString::clear` * `OsString::capacity` * `OsString::reserve` * `OsString::reserve_exact` * `OsStr::is_empty` * `OsStr::len` * `std::os::unix::thread` * `RawPthread` * `JoinHandleExt` * `JoinHandleExt::as_pthread_t` * `JoinHandleExt::into_pthread_t` * `HashSet::hasher` * `HashMap::hasher` * `CommandExt::exec` * `File::try_clone` * `SocketAddr::set_ip` * `SocketAddr::set_port` * `SocketAddrV4::set_ip` * `SocketAddrV4::set_port` * `SocketAddrV6::set_ip` * `SocketAddrV6::set_port` * `SocketAddrV6::set_flowinfo` * `SocketAddrV6::set_scope_id` * `<[T]>::copy_from_slice` * `ptr::read_volatile` * `ptr::write_volatile` * The `#[deprecated]` attribute * `OpenOptions::create_new` Deprecated * `std::raw::Slice` - use raw parts of `slice` module instead * `std::raw::Repr` - use raw parts of `slice` module instead * `str::char_range_at` - use slicing plus `chars()` plus `len_utf8` * `str::char_range_at_reverse` - use slicing plus `chars().rev()` plus `len_utf8` * `str::char_at` - use slicing plus `chars()` * `str::char_at_reverse` - use slicing plus `chars().rev()` * `str::slice_shift_char` - use `chars()` plus `Chars::as_str` * `CommandExt::session_leader` - use `before_exec` instead.

2016-04-08Blacklist fn item types from being used with variadic functions.Eduard Burtescu-6/+28
2016-04-07Auto merge of #32016 - nikomatsakis:incr-comp-save, r=mwbors-7/+7
Save/load incremental compilation dep graph Contains the code to serialize/deserialize the dep graph to disk between executions. We also hash the item contents and compare to the new hashes. Also includes a unit test harness. There are definitely some known limitations, such as https://github.com/rust-lang/rust/issues/32014 and https://github.com/rust-lang/rust/issues/32015, but I am leaving those for follow-up work. Note that this PR builds on https://github.com/rust-lang/rust/pull/32007, so the overlapping commits can be excluded from review. r? @michaelwoerister

2016-04-07Rollup merge of #32674 - jseyfried:1422_groundwork, r=nikomatsakisManish Goregaokar-0/+55
Lay groundwork for RFC 1422 and improve `PrivateItemsInPublicInterfacesVisitor` This PR lays groundwork for RFC 1422 (cc #32409) and improves `PrivateItemsInPublicInterfacesVisitor`. More specifically, it - Refactors away `hir::Visibility::inherit_from`, the semantics of which are obsolete. - Makes `hir::Visibility` non-`Copy` so that we will be able to add new variants to represent `pub(restricted)` (for example, `Visibility::Restricted(Path)`). - Adds a new `Copy` type `ty::Visibility` that represents a visibility value, i.e. a characterization of where an item is accessible. This is able to represent `pub(restricted)` visibilities. - Improves `PrivateItemsInPublicInterfacesVisitor` so that it checks for items in an interface that are less visible than the interface. This fixes #30079 but doesn't change any other behavior. r? @nikomatsakis

You can now pass `-Z incremental=dir` as well as saying `-Z query-dep-graph` if you want to enable queries for some other purpose. Accessor functions take the place of computed boolean flags.

Fix "consider removing this semicolon" help Check last statement in a block, not the first. Example of current weirdness: http://is.gd/w80J9h The help was only rarely emitted, and if so, often incorrectly (see above playpen). It was basically only useful with single-statement functions.

2016-04-04Auto merge of #32328 - jseyfried:coherence, r=nikomatsakisbors-6/+11
resolve: Improve import failure detection and lay groundwork for RFC 1422 This PR improves import failure detection and lays some groundwork for RFC 1422. More specifically, it - Avoids recomputing the resolution of an import directive's module path. - Refactors code in `resolve_imports` that does not scale to the arbitrarily many levels of visibility that will be required by RFC 1422. - Replaces `ModuleS`'s fields `public_glob_count`, `private_glob_count`, and `resolved_globs` with a list of glob import directives `globs`. - Replaces `NameResolution`'s fields `pub_outstanding_references` and `outstanding_references` with a field `single_imports` of a newly defined type `SingleImports`. - Improves import failure detection by detecting cycles that include single imports (currently, only cycles of globs are detected). This fixes #32119. r? @nikomatsakis
2016-04-04Auto merge of #32647 - Amanieu:checked_atomic_intrinsics, r=eddybbors-0/+117
Only allow using the atomic intrinsics on integer types Using these with non-integer types results in LLVM asserts. Atomic operations on non-integer types will require values be transmuted into an integer type of suitable size. This doesn't affect the standard library since `AtomicBool` and `AtomicPtr` currently use `usize` for atomic operations. r? @eddyb

When deciding on a coinductive match, we were examining the new obligation and the backtrace, but not the *current* obligation that goes in between the two. Refactoring the code to just have the cycle given as input also made things a lot simpler.

diagnostics: make paths to external items more visible This PR changes the reported path for an external item so that it is visible from at least one local module (i.e. it does not use any inaccessible external modules) if possible. If the external item's crate was declared with an `extern crate`, the path is guarenteed to use the `extern crate`. Fixes #23224, fixes #23355, fixes #26635, fixes #27165. r? @nrc

2016-03-31Rollup merge of #32494 - pnkfelix:gate-parser-recovery-via-debugflag, r=nrcManish Goregaokar-0/+16
Gate parser recovery via debugflag Gate parser recovery via debugflag Put in `-Z continue_parse_after_error` This works by adding a method, `fn abort_if_no_parse_recovery`, to the diagnostic handler in `syntax::errors`, and calling it after each error is emitted in the parser. (We might consider adding a debugflag to do such aborts in other places where we are currently attempting recovery, such as resolve, but I think the parser is the really important case to handle in the face of #31994 and the parser bugs of varying degrees that were injected by parse error recovery.) r? @nikomatsakis
