2017-06-16Introduce tidy lint to check for inconsistent tracking issuesest31-1/+1
This commit * Refactors the collect_lib_features function to work in a non-checking mode (no bad pointer needed, and list of lang features). * Introduces checking whether unstable/stable tags for a given feature have inconsistent tracking issues. * Fixes such inconsistencies throughout the codebase.

2017-06-04Add overflow checking for str::get with inclusive rangesScott McMurray-4/+12
Fixes #42401
2017-06-04Delegate str:Index(Mut) to SliceIndex<str>Scott McMurray-37/+18
Move any extra logic that the former had into the latter, so they're consistent.
2017-05-24Rollup merge of #42134 - scottmcm:rangeinclusive-struct, r=aturonMark Simulacrum-40/+19
Make RangeInclusive just a two-field struct Not being an enum improves ergonomics and consistency, especially since NonEmpty variant wasn't prevented from being empty. It can still be iterable without an extra "done" bit by making the range have !(start <= end), which is even possible without changing the Step trait. Implements merged https://github.com/rust-lang/rfcs/pull/1980; tracking issue https://github.com/rust-lang/rust/issues/28237. This is definitely a breaking change to anything consuming `RangeInclusive` directly (not as an Iterator) or constructing it without using the sugar. Is there some change that would make sense before this so compilation failures could be compatibly fixed ahead of time? r? @aturon (as FCP proposer on the RFC)

Correct some stability versions These were found by running tidy on stable versions of rust and finding features stabilised with the wrong version numbers.

Added links to types in from_utf8 description References #29375. Link to types mentioned in the documentation for `from_utf8` (`str`, `&[u8`], etc). Paragraphs were reformatted to keep any one line from being excessively long, but are otherwise unchanged.

Rename TryFrom's associated type and implement str::parse using TryFrom. Per discussion on the tracking issue, naming `TryFrom`'s associated type `Error` is generally more consistent with similar traits in the Rust ecosystem, and what people seem to assume it should be called. It also helps disambiguate from `Result::Err`, the most common "Err". See https://github.com/rust-lang/rust/issues/33417#issuecomment-269108968. `TryFrom<&str>` and `FromStr` are equivalent, so have the latter provide the former to ensure that. Using `TryFrom` in the implementation of `str::parse` means types that implement either trait can use it. When we're ready to stabilize `TryFrom`, we should update `FromStr` to suggest implementing `TryFrom<&str>` instead for new code. See https://github.com/rust-lang/rust/issues/33417#issuecomment-277175994 and https://github.com/rust-lang/rust/issues/33417#issuecomment-277253827. Refs #33417.

2017-03-14Add tracking issue number for Utf8Error::error_lenSimon Sapin-1/+1
2017-03-14Replace Utf8Error::resume_from with Utf8Error::error_lenSimon Sapin-10/+12
Their relationship is: * `resume_from = error_len.map(|l| l + valid_up_to)` * error_len is always one of None, Some(1), Some(2), or Some(3). When I started using resume_from I almost always ended up subtracting valid_up_to to obtain error_len. Therefore the latter is what should be provided in the first place.
2017-03-14Add Utf8Error::resume_from, to help incremental and/or lossy decoding.Simon Sapin-22/+56
Without this, code outside of the standard library needs to reimplement most of the logic `from_utf8` to interpret the bytes after `valid_up_to()`.

2017-01-12Auto merge of #37926 - bluss:from-utf8-small-simplification, r=sfacklerbors-27/+26
UTF-8 validation: Compute block end upfront Simplify the conditional used for ensuring that the whole word loop is only used if there are at least two whole words left to read. This makes the function slightly smaller and simpler, a 0-5% reduction in runtime for various test cases.
2017-01-03Auto merge of #38066 - bluss:string-slice-error, r=sfacklerbors-4/+22
Use more specific panic message for &str slicing errors Separate out of bounds errors from character boundary errors, and print more details for character boundary errors. It reports the first error it finds in: 1. begin out of bounds 2. end out of bounds 3. begin <= end violated 3. begin not char boundary 5. end not char boundary. Example: &"abcαβγ"[..4] thread 'str::test_slice_fail_boundary_1' panicked at 'byte index 4 is not a char boundary; it is inside 'α' (bytes 3..5) of `abcαβγ`' Fixes #38052
