2019-11-06Rollup merge of #66098 - estebank:path-asciption-typo, r=CentrilMazdak Farrokhzad-4/+12
Detect `::` -> `:` typo when involving turbofish Fix #65569.
2019-11-06Rollup merge of #66054 - petrochenkov:delspan, r=estebankMazdak Farrokhzad-2/+2
syntax: Avoid span arithmetic for delimiter tokens The +/-1 logic is from the time where the whole group had a single span and the delimiter spans had to be calculated from it. Now the delimiters have their own spans which are constructed by lexer or proc macro API and can be used directly. If those spans are not perfect, then it should be fixed by tweaking the corresponding lexer logic rather than by trying to add or substract `1` from the span boundaries. Fixes https://github.com/rust-lang/rust/issues/62524 r? @estebank

`Span` cannot represent `span.hi < span.lo` So we can remove the corresponding checks from various code

2019-11-04Auto merge of #65838 - estebank:resilient-recovery, r=Centrilbors-48/+93
Reduce amount of errors given unclosed delimiter When in a file with a non-terminated item, catch the error and consume the block instead of trying to recover it on a more granular way in order to reduce the amount of unrelated errors that would be fixed after adding the missing closing brace. Also point out the possible location of the missing closing brace. Fix #63690.

2019-10-18Rollup merge of #65455 - ↵Tyler Mandry-11/+10
nnethercote:avoid-unnecessary-TokenTree-to-TokenStream-conversions, r=petrochenkov Avoid unnecessary `TokenTree` to `TokenStream` conversions A `TokenStream` contains any number of `TokenTrees`. Therefore, a single `TokenTree` can be promoted to a `TokenStream`. But doing so costs two allocations: one for the single-element `Vec`, and one for the `Lrc`. (An `IsJoint` value also must be added; the default is `NonJoint`.) The current code converts `TokenTree`s to `TokenStream`s unnecessarily in a few places. This PR removes some of these unnecessary conversions, both simplifying the code and speeding it up. r? @petrochenkov
