2018-12-17Auto merge of #56737 - nnethercote:TokenStream-improvements, r=petrochenkovbors-3/+3
`TokenStream` improvements Some `TokenStream` improvements: shrinking `TokenStream` and some other types, and some other code clean-ups.
2018-12-15Rollup merge of #56679 - euclio:external-doc-parse, r=estebankPietro Albini-12/+56
overhaul external doc attribute diagnostics This PR improves the error handling and spans for the external doc attribute. Many cases that silently failed before now emit errors, spans are tightened, and the errors have help and suggestions. I tried to address all the cases that users ran into in the tracking issue. cc #44732 r? @QuietMisdreavus
2018-12-12Rename `TokenStream::concat` and remove `TokenStream::concat_rc_vec`.Nicholas Nethercote-3/+3
`TokenStream::new` is a better name for the former, and the latter is now just equivalent to `TokenStream::Stream`.

Also, provide a suggestion for the correct syntax.
2018-12-10Remove `tokenstream::Delimited`.Nicholas Nethercote-32/+31
Because it's an extra type layer that doesn't really help; in a couple of places it actively gets in the way, and overall removing it makes the code nicer. It does, however, move `tokenstream::TokenTree` further away from the `TokenTree` in `quote.rs`. More importantly, this change reduces the size of `TokenStream` from 48 bytes to 40 bytes on x86-64, which is enough to slightly reduce instruction counts on numerous benchmarks, the best by 1.5%. Note that `open_tt` and `close_tt` have gone from being methods on `Delimited` to associated methods of `TokenTree`.

2018-12-07use top level `fs` functions where appropriateAndy Russell-54/+47
This commit replaces many usages of `File::open` and reading or writing with `fs::read_to_string`, `fs::read` and `fs::write`. This reduces code complexity, and will improve performance for most reads, since the functions allocate the buffer to be the size of the file. I believe that this commit will not impact behavior in any way, so some matches will check the error kind in case the file was not valid UTF-8. Some of these cases may not actually care about the error.

2018-12-06Auto merge of #54517 - mcr431:53956-panic-on-include_bytes-of-own-file, ↵bors-7/+11
r=michaelwoerister 53956 panic on include bytes of own file fix #53956 When using `include_bytes!` on a source file in the project, compiler would panic on subsequent compilations because `expand_include_bytes` would overwrite files in the source_map with no source. This PR changes `expand_include_bytes` to check source_map and use the already existing src, if any.
