2014-11-13Move abs_sub to FloatMathBrendan Zabarauskas-1/+23
This removes the need for libcore to depend on libm. `abs_sub` is not as useful for integers.

2014-11-12Fix remaining documentation to reflect fail!() -> panic!()Barosl Lee-6/+6
Throughout the docs, "failure" was replaced with "panics" if it means a task panic. Otherwise, it remained as is, or changed to "errors" to clearly differentiate it from a task panic.
2014-11-07Fixing #18659juxiliary-1/+17
Changes the radix multiplier to start at -0.0 instead of -1.0 when reading strings that start with '-'.
2014-11-06Prelude: rename and consolidate extension traitsAaron Turon-2/+2
This commit renames a number of extension traits for slices and string slices, now that they have been refactored for DST. In many cases, multiple extension traits could now be consolidated. Further consolidation will be possible with generalized where clauses. The renamings are consistent with the [new `-Prelude` suffix](https://github.com/rust-lang/rfcs/pull/344). There are probably a few more candidates for being renamed this way, but that is left for API stabilization of the relevant modules. Because this renames traits, it is a: [breaking-change] However, I do not expect any code that currently uses the standard library to actually break. Closes #17917
2014-11-04Deprecate {f32, f64}::from_str_hexBrendan Zabarauskas-80/+27
This is now covered by `FromStrRadix::from_str_radix`
2014-11-04Simplify float string conversion function furtherBrendan Zabarauskas-161/+115
We now have a really simple function signature: pub fn from_str_radix_float<T: Float>(src: &str, radix: uint) -> Option<T> By removing some of the arguments, we remove the possibility of some invalid states.

2014-11-01collections: Remove all collections traitsAlex Crichton-1/+0
As part of the collections reform RFC, this commit removes all collections traits in favor of inherent methods on collections themselves. All methods should continue to be available on all collections. This is a breaking change with all of the collections traits being removed and no longer being in the prelude. In order to update old code you should move the trait implementations to inherent implementations directly on the type itself. Note that some traits had default methods which will also need to be implemented to maintain backwards compatibility. [breaking-change] cc #18424

2014-10-30collections: Enable IndexMut for some collectionsAlex Crichton-2/+2
This commit enables implementations of IndexMut for a number of collections, including Vec, RingBuf, SmallIntMap, TrieMap, TreeMap, and HashMap. At the same time this deprecates the `get_mut` methods on vectors in favor of using the indexing notation. cc #18424
2014-10-29Rename fail! to panic!Steve Klabnik-7/+7
https://github.com/rust-lang/rfcs/pull/221 The current terminology of "task failure" often causes problems when writing or speaking about code. You often want to talk about the possibility of an operation that returns a Result "failing", but cannot because of the ambiguity with task failure. Instead, you have to speak of "the failing case" or "when the operation does not succeed" or other circumlocutions. Likewise, we use a "Failure" header in rustdoc to describe when operations may fail the task, but it would often be helpful to separate out a section describing the "Err-producing" case. We have been steadily moving away from task failure and toward Result as an error-handling mechanism, so we should optimize our terminology accordingly: Result-producing functions should be easy to describe. To update your code, rename any call to `fail!` to `panic!` instead. Assuming you have not created your own macro named `panic!`, this will work on UNIX based systems: grep -lZR 'fail!' . | xargs -0 -l sed -i -e 's/fail!/panic!/g' You can of course also do this by hand.

2014-10-20auto merge of #18070 : alexcrichton/rust/spring-cleaning, r=aturonbors-174/+26
This is a large spring-cleaning commit now that the 0.12.0 release has passed removing an amount of deprecated functionality. This removes a number of deprecated crates (all still available as cargo packages in the rust-lang organization) as well as a slew of deprecated functions. All `#[crate_id]` support has also been removed. I tried to avoid anything that was recently deprecated, but I may have missed something! The major pain points of this commit is the fact that rustc/syntax have `#[allow(deprecated)]`, but I've removed that annotation so moving forward they should be cleaned up as we go.

2014-10-19Remove a large amount of deprecated functionalityAlex Crichton-174/+26
Spring cleaning is here! In the Fall! This commit removes quite a large amount of deprecated functionality from the standard libraries. I tried to ensure that only old deprecated functionality was removed. This is removing lots and lots of deprecated features, so this is a breaking change. Please consult the deprecation messages of the deleted code to see how to migrate code forward if it still needs migration. [breaking-change]
2014-10-13Clean up rustc warnings.NODA, Kai-12/+22
compiletest: compact "linux" "macos" etc.as "unix". liballoc: remove a superfluous "use". libcollections: remove invocations of deprecated methods in favor of their suggested replacements and use "_" for a loop counter. libcoretest: remove invocations of deprecated methods; also add "allow(deprecated)" for testing a deprecated method itself. libglob: use "cfg_attr". libgraphviz: add a test for one of data constructors. libgreen: remove a superfluous "use". libnum: "allow(type_overflow)" for type cast into u8 in a test code. librustc: names of static variables should be in upper case. libserialize: v[i] instead of get(). libstd/ascii: to_lowercase() instead of to_lower(). libstd/bitflags: modify AnotherSetOfFlags to use i8 as its backend. It will serve better for testing various aspects of bitflags!. libstd/collections: "allow(deprecated)" for testing a deprecated method itself. libstd/io: remove invocations of deprecated methods and superfluous "use". Also add #[test] where it was missing. libstd/num: introduce a helper function to effectively remove invocations of a deprecated method. libstd/path and rand: remove invocations of deprecated methods and superfluous "use". libstd/task and libsync/comm: "allow(deprecated)" for testing a deprecated method itself. libsync/deque: remove superfluous "unsafe". libsync/mutex and once: names of static variables should be in upper case. libterm: introduce a helper function to effectively remove invocations of a deprecated method. We still see a few warnings about using obsoleted native::task::spawn() in the test modules for libsync. I'm not sure how I should replace them with std::task::TaksBuilder and native::task::NativeTaskBuilder (dependency to libstd?) Signed-off-by: NODA, Kai <nodakai@gmail.com>

2014-08-16librustc: Forbid external crates, imports, and/or items from beingPatrick Walton-2/+0
declared with the same name in the same scope. This breaks several common patterns. First are unused imports: use foo::bar; use baz::bar; Change this code to the following: use baz::bar; Second, this patch breaks globs that import names that are shadowed by subsequent imports. For example: use foo::*; // including `bar` use baz::bar; Change this code to remove the glob: use foo::{boo, quux}; use baz::bar; Or qualify all uses of `bar`: use foo::{boo, quux}; use baz; ... baz::bar ... Finally, this patch breaks code that, at top level, explicitly imports `std` and doesn't disable the prelude. extern crate std; Because the prelude imports `std` implicitly, there is no need to explicitly import it; just remove such directives. The old behavior can be opted into via the `import_shadowing` feature gate. Use of this feature gate is discouraged. This implements RFC #116. Closes #16464. [breaking-change]

2014-06-30libstd: set baseline stability levels.Aaron Turon-0/+6
Earlier commits have established a baseline of `experimental` stability for all crates under the facade (so their contents are considered experimental within libstd). Since `experimental` is `allow` by default, we should use the same baseline stability for libstd itself. This commit adds `experimental` tags to all of the modules defined in `std`, and `unstable` to `std` itself.

2014-06-24librustc: Remove the fallback to `int` from typechecking.Niko Matsakis-15/+15
This breaks a fair amount of code. The typical patterns are: * `for _ in range(0, 10)`: change to `for _ in range(0u, 10)`; * `println!("{}", 3)`: change to `println!("{}", 3i)`; * `[1, 2, 3].len()`: change to `[1i, 2, 3].len()`. RFC #30. Closes #6023. [breaking-change]

2014-06-06Rename Iterator::len to countAaron Turon-1/+0
This commit carries out the request from issue #14678: > The method `Iterator::len()` is surprising, as all the other uses of > `len()` do not consume the value. `len()` would make more sense to be > called `count()`, but that would collide with the current > `Iterator::count(|T| -> bool) -> unit` method. That method, however, is > a bit redundant, and can be easily replaced with > `iter.filter(|x| x < 5).count()`. > After this change, we could then define the `len()` method > on `iter::ExactSize`. Closes #14678. [breaking-change]
2014-05-31rustdoc: Create anchor pages for primitive typesAlex Crichton-0/+22
This commit adds support in rustdoc to recognize the `#[doc(primitive = "foo")]` attribute. This attribute indicates that the current module is the "owner" of the primitive type `foo`. For rustdoc, this means that the doc-comment for the module is the doc-comment for the primitive type, plus a signal to all downstream crates that hyperlinks for primitive types will be directed at the crate containing the `#[doc]` directive. Additionally, rustdoc will favor crates closest to the one being documented which "implements the primitive type". For example, documentation of libcore links to libcore for primitive types, but documentation for libstd and beyond all links to libstd for primitive types. This change involves no compiler modifications, it is purely a rustdoc change. The landing pages for the primitive types primarily serve to show a list of implemented traits for the primitive type itself. The primitive types documented includes both strings and slices in a semi-ad-hoc way, but in a way that should provide at least somewhat meaningful documentation. Closes #14474
2014-05-30std: Rename {Eq,Ord} to Partial{Eq,Ord}Alex Crichton-6/+6
This is part of the ongoing renaming of the equality traits. See #12517 for more details. All code using Eq/Ord will temporarily need to move to Partial{Eq,Ord} or the Total{Eq,Ord} traits. The Total traits will soon be renamed to {Eq,Ord}. cc #12517 [breaking-change]
2014-05-29std: Recreate a `rand` moduleAlex Crichton-14/+14
This commit shuffles around some of the `rand` code, along with some reorganization. The new state of the world is as follows: * The librand crate now only depends on libcore. This interface is experimental. * The standard library has a new module, `std::rand`. This interface will eventually become stable. Unfortunately, this entailed more of a breaking change than just shuffling some names around. The following breaking changes were made to the rand library: * Rng::gen_vec() was removed. This has been replaced with Rng::gen_iter() which will return an infinite stream of random values. Previous behavior can be regained with `rng.gen_iter().take(n).collect()` * Rng::gen_ascii_str() was removed. This has been replaced with Rng::gen_ascii_chars() which will return an infinite stream of random ascii characters. Similarly to gen_iter(), previous behavior can be emulated with `rng.gen_ascii_chars().take(n).collect()` * {IsaacRng, Isaac64Rng, XorShiftRng}::new() have all been removed. These all relied on being able to use an OSRng for seeding, but this is no longer available in librand (where these types are defined). To retain the same functionality, these types now implement the `Rand` trait so they can be generated with a random seed from another random number generator. This allows the stdlib to use an OSRng to create seeded instances of these RNGs. * Rand implementations for `Box<T>` and `@T` were removed. These seemed to be pretty rare in the codebase, and it allows for librand to not depend on liballoc. Additionally, other pointer types like Rc<T> and Arc<T> were not supported. If this is undesirable, librand can depend on liballoc and regain these implementations. * The WeightedChoice structure is no longer built with a `Vec<Weighted<T>>`, but rather a `&mut [Weighted<T>]`. This means that the WeightedChoice structure now has a lifetime associated with it. * The `sample` method on `Rng` has been moved to a top-level function in the `rand` module due to its dependence on `Vec`. cc #13851 [breaking-change]
