2015-10-23parser: fix erroneous commentAleksey Kladov-2/+15
Qualified paths allow full path after the `>::`. For example ```rust <T as Foo>::U::generic_method::<f64>() ``` The example is taken from `test/run-pass/associated-item-long-paths.rs`.
2015-10-20Auto merge of #29148 - petrochenkov:noshow, r=alexcrichtonbors-5/+3
Closes https://github.com/rust-lang/rust/issues/29145 [breaking-change], needs a crater run.
2015-10-20Auto merge of #29152 - petrochenkov:derstab, r=alexcrichtonbors-1/+1
The attributes are copied from the item for which the trait impl is derived I think now we can close these two issues: https://github.com/rust-lang/rust/issues/13054 - `allow`, `deny` etc. were already copied, now `stable` and `unstable` are copied as well. https://github.com/rust-lang/rust/issues/18969 - I'm not sure this is needed, insta-stability were good enough so far, copied stability will be better. Nonetheless, it can be subsumed by some more general mechanism for supplying arbitrary not necessarily stability related attributes (for example `inline`) to derived impls and their methods (I haven't found an open issue for such mechanism). r? @alexcrichton

Closes https://github.com/rust-lang/rust/issues/28750 `Arm` and `Generics` don't have spans at all, so it's not a visitor's problem, `visit_struct_def` was fixed in https://github.com/rust-lang/rust/pull/28816
2015-10-16Auto merge of #29014 - petrochenkov:stability, r=brsonbors-125/+173
Stricter checking of stability attributes + enforcement of their invariants at compile time (+ removed dead file librustc_front/attr.rs) I intended to enforce use of `reason` for unstable items as well (it normally presents for new items), but it turned out too intrusive, many older unstable items don't have `reason`s. r? @aturon I'm studying how stability works and do some refactoring along the way, so it's probably not the last PR.

This is a [breaking change]. @brson could you do a Crater run with this PR please? Lets not land till Crater says its OK. This was discussed at https://internals.rust-lang.org/t/does-anyone-use-the-push-pop-unsafe-macros/2702
2015-10-14Auto merge of #28827 - thepowersgang:unsafe-const-fn-2, r=Aatchbors-3/+8
This is the original test implementation, which works according to the tests I wrote, but might need a review.

2015-10-10Auto merge of #28932 - barosl:empty-comment, r=alexcrichtonbors-2/+3
Previously, `/**/` was incorrectly regarded as a doc comment because it starts with `/**` and ends with `*/`. However, this caused an ICE because some code assumed that the length of a doc comment is at least 5. This commit adds an additional check to `is_block_doc_comment` that tests the length of the input. Fixes #28844.

2015-10-06Add RFC 1238's `unsafe_destructor_blind_to_params` (UGEH) where needed.Felix S. Klock II-4/+4
I needed it in `RawVec`, `Vec`, and `TypedArena` for `rustc` to bootstrap; but of course that alone was not sufficient for `make check`. Later I added `unsafe_destructor_blind_to_params` to collections, in particular `LinkedList` and `RawTable` (the backing representation for `HashMap` and `HashSet`), to get the regression tests exercising cyclic structure from PR #27185 building. ---- Note that the feature is `dropck_parametricity` (which is not the same as the attribute's name). We will almost certainly vary our strategy here in the future, so it makes some sense to have a not-as-ugly name for the feature gate. (The attribute name was deliberately selected to be ugly looking.)
2015-10-06Non-parametric dropck; instead trust an unsafe attribute (RFC 1238).Felix S. Klock II-0/+9
Implement cannot-assume-parametricity (CAP) from RFC 1238, and add the UGEH attribute. ---- Note that we check for the attribute attached to the dtor method, not the Drop impl. (This is just to match the specification of RFC and the tests; I am not wedded to this approach.)
