2015-03-17Rollup merge of #23329 - jbcrail:rm-syntax-highlight, r=sanxiynManish Goregaokar-20/+21
As suggested by @steveklabnik in #23254, I removed the redundant Rust syntax highlighting from the documentation.

2015-03-13Deprecate range, range_step, count, distributionsAaron Turon-2/+0
This commit deprecates the `count`, `range` and `range_step` functions in `iter`, in favor of range notation. To recover all existing functionality, a new `step_by` adapter is provided directly on `ops::Range` and `ops::RangeFrom`. [breaking-change]

2015-03-09rand: Use wrapping operations everywhereAlex Crichton-121/+125
There was a buildbot failure recently of an arithmetic overflow in the isaac module of the rand crate, so I've imported the isaac implementation from out-of-tree which makes somewhat more liberal usage of the wrapping primitives. Hopefull this quelches any future overflow!

2015-03-03Auto merge of #22532 - pnkfelix:arith-overflow, r=pnkfelix,eddybbors-74/+78
Rebase and follow-through on work done by @cmr and @aatch. Implements most of rust-lang/rfcs#560. Errors encountered from the checks during building were fixed. The checks for division, remainder and bit-shifting have not been implemented yet. See also PR #20795 cc @Aatch ; cc @nikomatsakis
2015-03-03Accommodate arith-overflow in `rand` and `std::rand`.Felix S. Klock II-36/+39
Regarding the `rand` changes: It is unfortunate that Wrapping(T) does not support the `+=` operator. We may want to try to fix that before 1.0 to make porting code like this palatable. Regarding `std::rand`, just arith-overflow in first example from `std::rand::random()` doc.
2015-03-03Add `core::num::wrapping` and fix overflow errors.James Miller-38/+39
Many of the core rust libraries have places that rely on integer wrapping behaviour. These places have been altered to use the wrapping_* methods: * core::hash::sip - A number of macros * core::str - The `maximal_suffix` method in `TwoWaySearcher` * rustc::util::nodemap - Implementation of FnvHash * rustc_back::sha2 - A number of macros and other places * rand::isaac - Isaac64Rng, changed to use the Wrapping helper type Some places had "benign" underflow. This is when underflow or overflow occurs, but the unspecified value is not used due to other conditions. * collections::bit::Bitv - underflow when `self.nbits` is zero. * collections::hash::{map,table} - Underflow when searching an empty table. Did cause undefined behaviour in this case due to an out-of-bounds ptr::offset based on the underflowed index. However the resulting pointers would never be read from. * syntax::ext::deriving::encodable - Underflow when calculating the index of the last field in a variant with no fields. These cases were altered to avoid the underflow, often by moving the underflowing operation to a place where underflow could not happen. There was one case that relied on the fact that unsigned arithmetic and two's complement arithmetic are identical with wrapping semantics. This was changed to use the wrapping_* methods. Finally, the calculation of variant discriminants could overflow if the preceeding discriminant was `U64_MAX`. The logic in `rustc::middle::ty` for this was altered to avoid the overflow completely, while the remaining places were changed to use wrapping methods. This is because `rustc::middle::ty::enum_variants` now throws an error when the calculated discriminant value overflows a `u64`. This behaviour can be triggered by the following code: ``` enum Foo { A = U64_MAX, B } ``` This commit also implements the remaining integer operators for Wrapped<T>.
2015-03-02Use `const`s instead of `static`s where appropriateFlorian Zeitz-7/+7
This changes the type of some public constants/statics in libunicode. Notably some `&'static &'static [(char, char)]` have changed to `&'static [(char, char)]`. The regexp crate seems to be the sole user of these, yet this is technically a [breaking-change]

2015-02-18rollup merge of #22287: Ryman/purge_carthographersAlex Crichton-2/+2
This overlaps with #22276 (I left make check running overnight) but covers a number of additional cases and has a few rewrites where the clones are not even necessary. This also implements `RandomAccessIterator` for `iter::Cloned` cc @steveklabnik, you may want to glance at this before #22281 gets the bors treatment

2015-02-06Rollup merge of #21926 - mzabaluev:raw-lifetime, r=alexcrichtonManish Goregaokar-2/+2
New functions, `slice::from_raw_parts` and `slice::from_raw_parts_mut`, are added to implement the lifetime convention as agreed in rust-lang/rfcs#556. The functions `slice::from_raw_buf` and `slice::from_raw_mut_buf` are left deprecated for the time being. Holding back on changing the signature of `std::ffi::c_str_to_bytes` as consensus in rust-lang/rfcs#592 is building to replace it with a composition of other functions. Contribution to #21923.
2015-02-06Rollup merge of #21925 - sfackler:allow-missing-copy, r=alexcrichtonManish Goregaokar-1/+0
This was particularly helpful in the time just after OIBIT's implementation to make sure things that were supposed to be Copy continued to be, but it's now creates a lot of noise for types that intentionally don't want to be Copy. r? @alexcrichton
