Small stuff... might as well get it into the tree. One new test case, some issue # cleanup, remove some unused imports.
|
|
This fixes private statics and functions from being usable cross-crates, along
with some bad privacy error messages. This is a reopening of #8365 with all the
privacy checks in privacy.rs instead of resolve.rs (where they should be
anyway).
These maps of exported items will hopefully get used for generating
documentation by rustdoc
Closes #8592

Work a bit towards #9157 "Remove Either". These instances don't need to use Either and are better expressed in other ways (removing allocations and simplifying types).
|
|
The arg or capture type alias was actually never used for the capture
case, so the code is simplified with `Either<arg, ()>` replaced by `arg`

This way syntax extensions can generate unsafe blocks without worrying about
them generating unnecessary unsafe warnings. Perhaps a special keyword could be
added to be used in macros, but I don't think that's the best solution.

Lots of downstream changes in librustc, should be infinitesimally faster.

Also redefine all of the standard logging macros to use more rust code instead
of custom LLVM translation code. This makes them a bit easier to understand, but
also more flexibile for future types of logging.
Additionally, this commit removes the LogType language item in preparation for
changing how logging is performed.

`for` desugars to `loop` so it is trivial to just desugar to `loop` while
retaining any label.

r? anybody

This removes the stacking of type parameters that occurs when invoking
trait methods, and fixes all places in the standard library that were
relying on it. It is somewhat awkward in places; I think we'll probably
want something like the `Foo::<for T>::new()` syntax.
|
|
For example, `foo::<T>::bar::<U>`.
This doesn't enforce that the type parameters are in the right
positions, however.
|
|
They are still present as part of the borrow check.

* Get rid of by-value-self workarounds; it works now
* Remove type annotations, they're not needed anymore

When parsing a trait function, the function must end with either `;` or
`{` (signifying a default implementation). The error message incorrectly
stated that it must be `;` or `}`.
Fixes #6610.

pnkfelix/rust/fsk-issue3192-improve-parse-error-for-empty-struct-init, r=pcwalton,me
Fix #3192. r? anyone
There are 4 different new tests, to check some different scenarios for
what the parse context is at the time of recovery, becasue our
compile-fail infrastructure does not appear to handle verifying
error-recovery situations.
Differentiate between unit-like struct definition item and unit-like
struct construction in the error message.
----
More generally, outlines a more generic strategy for parse error
recovery: By committing to an expression/statement at set points in
the parser, we can then do some look-ahead to catch common mistakes
and skip over them.
One detail about this strategy is that you want to avoid emitting the
"helpful" message unless the input is reasonably close to the case of
interest. (E.g. do not warn about a potential unit struct for an
input of the form `let hmm = do foo { } { };`)
To accomplish this, I added (partial) last_token tracking; used for
`commit_stmt` support.
The check_for_erroneous_unit_struct_expecting fn returns bool to
signal whether it "made progress"; currently unused; this is meant for
use to compose several such recovery checks together in a loop.

Fix #5762 and various other aspects of object invocation.

`enum Token` was 192 bytes (64-bit), as pointed out by pnkfelix; the only
bloating variant being `INTERPOLATED(nonterminal)`.
Updating `enum nonterminal` to use ~ where variants included big types,
shrunk size_of(Token) to 32 bytes (64-bit).
I am unsure if the `nt_ident` variant should have an indirection, with
ast::ident being only 16 bytes (64-bit), but without this, enum Token
would be 40 bytes.
A dumb benchmark says that compilation time is unchanged, while peak
memory usage for compiling std.rs is down 3%

r? @graydon Also, notably, make rustpkgtest depend on the rustpkg executable (otherwise, tests that shell out to rustpgk might run when rustpkg doesn't exist).
|

This commit allows you to write:
extern mod x = "a/b/c";
which means rustc will search in the RUST_PATH for a package with
ID a/b/c, and bind it to the name `x` if it's found.
Incidentally, move get_relative_to from back::rpath into std::path
