2016-04-07Don't loop forever on error recovery with EOFNick Cameron-1/+10
closes #31804
2016-04-07Put in `-Z continue-parse-after-error`Felix S. Klock II-0/+9
This works by adding a boolean flag, `continue_after_error`, to `syntax::errors::Handler` that can be imperatively set to `true` or `false` via a new `fn set_continue_after_error`. The flag starts off true (since we generally try to recover from compiler errors, and `Handler` is shared across all phases). Then, during the `phase_1_parse_input`, we consult the setting of the `-Z continue-parse-after-error` debug flag to determine whether we should leave the flag set to `true` or should change it to `false`. ---- (We might consider adding a debugflag to do such aborts in other places where we are currently attempting recovery, such as resolve, but I think the parser is the really important case to handle in the face of #31994 and the parser bugs of varying degrees that were injected by parse error recovery.)
2016-04-07syntax: Stop the bump loop for trait items at } and EOF.Eduard Burtescu-9/+17
backport of 221d0fbad0b201ef9264d3c9a30cd8c143ed51b2 to beta with hand-resolution of conflicts and reverting to `try!` syntax.

2016-02-25Rollup merge of #31362 - jseyfried:fix_extern_crate_visibility, r=nikomatsakisManish Goregaokar-7/+0
This PR changes the visibility of extern crate declarations to match that of items (fixes #26775). To avoid breakage, the PR makes it a `public_in_private` lint to reexport a private extern crate, and it adds the lint `inaccessible_extern_crate` for uses of an inaccessible extern crate. The lints can be avoided by making the appropriate `extern crate` declaration public.

2016-02-21rustbuild: Sync some Cargo.toml/lib.rs dependenciesAlex Crichton-2/+1
The standard library doesn't depend on rustc_bitflags, so move it to explicit dependencies on all other crates. Additionally, the arena/fmt_macros deps could be dropped from libsyntax.
2016-02-18Remove unnecessary explicit lifetime bounds.Corey Farwell-11/+11
These explicit lifetimes can be ommitted because of lifetime elision rules. Instances were found using rust-clippy.
2016-02-17Auto merge of #31707 - GuillaumeGomez:macro_name, r=sfacklerbors-1/+6
I'm wondering if instead of a second help message, a note would be better. I let it up to reviewers.

And split `PatKind::Enum` into `PatKind::TupleStruct` and `PatKind::Path`. This is the HIR part of https://github.com/rust-lang/rust/pull/31581. This is also kind of a preparation for https://github.com/rust-lang/rfcs/pull/1492. r? @eddyb

This PR disallows non-inline modules without path annotations that are either in a block or in an inline module whose containing file is not a directory owner (fixes #29765). This is a [breaking-change]. r? @nikomatsakis

2016-02-15Add some simple error recovery to the parser and fix testsNick Cameron-28/+63
Some tests just add the extra errors, others I fix by doing some simple error recovery. I've tried to avoid doing too much in the hope of doing something more principled later. In general error messages are getting worse at this stage, but I think in the long run they will get better.

2016-02-14Auto merge of #31581 - petrochenkov:patrefact, r=Manishearthbors-133/+148
cc https://github.com/rust-lang/rust/pull/31487#issuecomment-182945101 plugin-[breaking-change] The first commit renames `ast::Pat_` to `ast::PatKind` and uses its variants in enum qualified form. I've also taken the opportunity and renamed `PatKind::Region` into `PatKind::Ref`. The second commit splits `PatKind::Enum` into `PatKind::TupleStruct` and `PatKind::UnitStruct`. So, pattern kinds now correspond to their struct/variant kinds - `Struct`, `TupleStruct` and `UnitStruct`. @nikomatsakis @nrc @arielb1 Are you okay with this naming scheme? An alternative possible naming scheme is `PatKind::StructVariant`, `PatKind::TupleVariant`, `PatKind::UnitVariant` (it's probably closer to the common use, but I like it less). I intend to apply these changes to HIR later, they should not necessarily go in the same nightly with https://github.com/rust-lang/rust/pull/31487 r? @Manishearth
