2016-01-24mk: Move from `-D warnings` to `#![deny(warnings)]`Alex Crichton-0/+1
This commit removes the `-D warnings` flag being passed through the makefiles to all crates to instead be a crate attribute. We want these attributes always applied for all our standard builds, and this is more amenable to Cargo-based builds as well. Note that all `deny(warnings)` attributes are gated with a `cfg(stage0)` attribute currently to match the same semantics we have today
2016-01-16libsyntax: accept only whitespace with the PATTERN_WHITE_SPACE propertyKevin Butler-0/+1
This aligns with unicode recommendations and should be stable for all future unicode releases. See http://unicode.org/reports/tr31/#R3. This renames `libsyntax::lexer::is_whitespace` to `is_pattern_whitespace` so potentially breaks users of libsyntax.

2015-12-05std: Stabilize APIs for the 1.6 releaseAlex Crichton-2/+0
This commit is the standard API stabilization commit for the 1.6 release cycle. The list of issues and APIs below have all been through their cycle-long FCP and the libs team decisions are listed below Stabilized APIs * `Read::read_exact` * `ErrorKind::UnexpectedEof` (renamed from `UnexpectedEOF`) * libcore -- this was a bit of a nuanced stabilization, the crate itself is now marked as `#[stable]` and the methods appearing via traits for primitives like `char` and `str` are now also marked as stable. Note that the extension traits themeselves are marked as unstable as they're imported via the prelude. The `try!` macro was also moved from the standard library into libcore to have the same interface. Otherwise the functions all have copied stability from the standard library now. * The `#![no_std]` attribute * `fs::DirBuilder` * `fs::DirBuilder::new` * `fs::DirBuilder::recursive` * `fs::DirBuilder::create` * `os::unix::fs::DirBuilderExt` * `os::unix::fs::DirBuilderExt::mode` * `vec::Drain` * `vec::Vec::drain` * `string::Drain` * `string::String::drain` * `vec_deque::Drain` * `vec_deque::VecDeque::drain` * `collections::hash_map::Drain` * `collections::hash_map::HashMap::drain` * `collections::hash_set::Drain` * `collections::hash_set::HashSet::drain` * `collections::binary_heap::Drain` * `collections::binary_heap::BinaryHeap::drain` * `Vec::extend_from_slice` (renamed from `push_all`) * `Mutex::get_mut` * `Mutex::into_inner` * `RwLock::get_mut` * `RwLock::into_inner` * `Iterator::min_by_key` (renamed from `min_by`) * `Iterator::max_by_key` (renamed from `max_by`) Deprecated APIs * `ErrorKind::UnexpectedEOF` (renamed to `UnexpectedEof`) * `OsString::from_bytes` * `OsStr::to_cstring` * `OsStr::to_bytes` * `fs::walk_dir` and `fs::WalkDir` * `path::Components::peek` * `slice::bytes::MutableByteVector` * `slice::bytes::copy_memory` * `Vec::push_all` (renamed to `extend_from_slice`) * `Duration::span` * `IpAddr` * `SocketAddr::ip` * `Read::tee` * `io::Tee` * `Write::broadcast` * `io::Broadcast` * `Iterator::min_by` (renamed to `min_by_key`) * `Iterator::max_by` (renamed to `max_by_key`) * `net::lookup_addr` New APIs (still unstable) * `<[T]>::sort_by_key` (added to mirror `min_by_key`) Closes #27585 Closes #27704 Closes #27707 Closes #27710 Closes #27711 Closes #27727 Closes #27740 Closes #27744 Closes #27799 Closes #27801 cc #27801 (doesn't close as `Chars` is still unstable) Closes #28968
2015-12-04Auto merge of #29850 - Kimundi:attributes_that_make_a_statement, r=pnkfelixbors-0/+1
See https://github.com/rust-lang/rfcs/pull/16 and https://github.com/rust-lang/rust/issues/15701 - Added syntax support for attributes on expressions and all syntax nodes in statement position. - Extended `#[cfg]` folder to allow removal of statements, and of expressions in optional positions like expression lists and trailing block expressions. - Extended lint checker to recognize lint levels on expressions and locals. - As per RFC, attributes are not yet accepted on `if` expressions. Examples: ```rust let x = y; { ... } assert_eq!((1, #[cfg(unset)] 2, 3), (1, 3)); let FOO = 0; ``` Implementation wise, there are a few rough corners and open questions: - The parser work ended up a bit ugly. - The pretty printer change was based mostly on guessing. - Similar to the `if` case, there are some places in the grammar where a new `Expr` node starts, but where it seemed weird to accept attributes and hence the parser doesn't. This includes: - const expressions in patterns - in the middle of an postfix operator chain (that is, after `.`, before indexing, before calls) - on range expressions, since `#[attr] x .. y` parses as `(#[attr] x) .. y`, which is inconsistent with `#[attr] .. y` which would parse as `#[attr] (.. y)` - Attributes are added as additional `Option<Box<Vec<Attribute>>>` fields in expressions and locals. - Memory impact has not been measured yet. - A cfg-away trailing expression in a block does not currently promote the previous `StmtExpr` in a block to a new trailing expr. That is to say, this won't work: ```rust let x = { #[cfg(foo)] Foo { data: x } #[cfg(not(foo))] Foo { data: y } }; ``` - One-element tuples can have their inner expression removed to become Unit, but just Parenthesis can't. Eg, `(#[cfg(unset)] x,) == ()` but `(#[cfg(unset)] x) == error`. This seemed reasonable to me since tuples and unit are type constructors, but could probably be argued either way. - Attributes on macro nodes are currently unconditionally dropped during macro expansion, which seemed fine since macro disappear at that point? - Attributes on `ast::ExprParens` will be prepend-ed to the inner expression in the hir folder. - The work on pretty printer tests for this did trigger, but not fix errors regarding macros: - expression `foo![]` prints as `foo!()` - expression `foo!{}` prints as `foo!()` - statement `foo![];` prints as `foo!();` - statement `foo!{};` prints as `foo!();` - statement `foo!{}` triggers a `None` unwrap ICE.
2015-11-27Auto merge of #30064 - fhartwig:macro-suggestions, r=sanxiynbors-0/+1
Fixes #13677 This does the same sort of suggestion for misspelt macros that we already do for misspelt identifiers. Example. Compiling this program: ```rust macro_rules! foo { ($e:expr) => ( $e ) } fn main() { fob!("hello!"); } ``` gives the following error message: ``` /Users/mcp/temp/test.rs:7:5: 7:8 error: macro undefined: 'fob!' /Users/mcp/temp/test.rs:7 fob!("hello!"); ^~~ /Users/mcp/temp/test.rs:7:5: 7:8 help: did you mean `foo`? /Users/mcp/temp/test.rs:7 fob!("hello!"); ``` I had to move the levenshtein distance function into libsyntax for this. Maybe this should live somewhere else (some utility crate?), but I couldn't find a crate to put it in that is imported by libsyntax and the other rustc crates.

2015-11-12Auto merge of #29544 - Ryman:reduce_doc_warnings, r=steveklabnikbors-1/+2
Did this alphabetically, so I didn't see [how `std` was doing things](https://dxr.mozilla.org/rust/source/src/libstd/lib.rs#215) till I was nearly finished. If you prefer to add crate-level-whitelists like std instead of test-level, I can rebase with that strategy. A number of these commits can probably be dropped as the crates don't have much to test, and are deprecated. Let me know which if any to drop! (can also squash after review if desired) r? @steveklabnik

2015-10-27Generalise associative operator parsingSimonas Kazlauskas-0/+1
This commit generalises parsing of associative operators from left-associative only (with some ugly hacks to support right-associative assignment) to properly left/right-associative operators. Parsing still is not general enough to handle non-associative, non-highest-precedence prefix or non-highest-precedence postfix operators (e.g. `..` range syntax), though. That should be fixed in the future. Lastly, this commit adds support for parsing right-associative `<-` (left arrow) operator with precedence higher than assignment as the operator for placement-in feature.
2015-10-25std: Stabilize library APIs for 1.5Alex Crichton-2/+0
This commit stabilizes and deprecates library APIs whose FCP has closed in the last cycle, specifically: Stabilized APIs: * `fs::canonicalize` * `Path::{metadata, symlink_metadata, canonicalize, read_link, read_dir, exists, is_file, is_dir}` - all moved to inherent methods from the `PathExt` trait. * `Formatter::fill` * `Formatter::width` * `Formatter::precision` * `Formatter::sign_plus` * `Formatter::sign_minus` * `Formatter::alternate` * `Formatter::sign_aware_zero_pad` * `string::ParseError` * `Utf8Error::valid_up_to` * `Iterator::{cmp, partial_cmp, eq, ne, lt, le, gt, ge}` * `<[T]>::split_{first,last}{,_mut}` * `Condvar::wait_timeout` - note that `wait_timeout_ms` is not yet deprecated but will be once 1.5 is released. * `str::{R,}MatchIndices` * `str::{r,}match_indices` * `char::from_u32_unchecked` * `VecDeque::insert` * `VecDeque::shrink_to_fit` * `VecDeque::as_slices` * `VecDeque::as_mut_slices` * `VecDeque::swap_remove_front` - (renamed from `swap_front_remove`) * `VecDeque::swap_remove_back` - (renamed from `swap_back_remove`) * `Vec::resize` * `str::slice_mut_unchecked` * `FileTypeExt` * `FileTypeExt::{is_block_device, is_char_device, is_fifo, is_socket}` * `BinaryHeap::from` - `from_vec` deprecated in favor of this * `BinaryHeap::into_vec` - plus a `Into` impl * `BinaryHeap::into_sorted_vec` Deprecated APIs * `slice::ref_slice` * `slice::mut_ref_slice` * `iter::{range_inclusive, RangeInclusive}` * `std::dynamic_lib` Closes #27706 Closes #27725 cc #27726 (align not stabilized yet) Closes #27734 Closes #27737 Closes #27742 Closes #27743 Closes #27772 Closes #27774 Closes #27777 Closes #27781 cc #27788 (a few remaining methods though) Closes #27790 Closes #27793 Closes #27796 Closes #27810 cc #28147 (not all parts stabilized)

2015-07-22Hack for "unsafety hygiene" -- `push_unsafe!` and `pop_unsafe!`.Felix S. Klock II-0/+1
Even after expansion, the generated expressions still track depth of such pushes (i.e. how often you have "pushed" without a corresponding "pop"), and we add a rule that in a context with a positive `push_unsafe!` depth, it is effectively an `unsafe` block context. (This way, we can inject code that uses `unsafe` features, but still contains within it a sub-expression that should inherit the outer safety checking setting, outside of the injected code.) This is a total hack; it not only needs a feature-gate, but probably should be feature-gated forever (if possible). ignore-pretty in test/run-pass/pushpop-unsafe-okay.rs
2015-07-20syntax: Suppress panic message on `fatal`Alex Crichton-0/+1
This commit ensures that the rustc thread does not leak a panic message whenever a call to `fatal` happens. This already happens for the main rustc thread as part of the `rustc_driver::monitor` function, but the compiler also spawns threads for other operations like `-C codegen-units`, and sometimes errors are emitted on these threads as well. To ensure that there's a consistent error-handling experience across threads this unifies these two to never print the panic message in the case of a normal and expected fatal error. This should also fix the flaky `asm-src-loc-codegen-units.rs` test as the output is sometimes garbled if diagnostics are printed while the panic message is also being printed.
2015-06-17collections: Split the `collections` featureAlex Crichton-2/+4
This commit also deprecates the `as_string` and `as_slice` free functions in the `string` and `vec` modules.
2015-06-17core: Split apart the global `core` featureAlex Crichton-1/+2
This commit shards the broad `core` feature of the libcore library into finer grained features. This split groups together similar APIs and enables tracking each API separately, giving a better sense of where each feature is within the stabilization process. A few minor APIs were deprecated along the way: * Iterator::reverse_in_place * marker::NoCopy
