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
|
|
As documented in issue #7945, these literal identifiers are all accepted by rust
today, but they should probably be disallowed (especially `'''`). This changes
all escapable sequences to being *required* to be escaped.
Closes #7945
I wanted to write the tests with more exact spans, but I think #9308 will be fixing that?

Progress on #7981
This doesn't completely close the issue because `struct A;` is still allowed, and it's a much larger change to disallow that. I'm also not entirely sure that we want to disallow that. Regardless, punting that discussion to the issue instead.

pnkfelix/rust/fsk-issue-4691-catch-bad-fsu-during-compute-moves, r=nikomatsakis
Resolves third bullet of #4691: if the functional-struct-update (FSU) expression `{ a: b, ..s }` causes `s` to move and `s` has a destructor, then the expression is illegal.

This is for consistency in naming conventions.
- ``std::num::Float::NaN()`` is changed to ``nan()``;
- ``std::num::Float.is_NaN()`` is changed to ``is_nan()``; and
- ``std::num::strconv::NumStrConv::NaN()`` is changed to ``nan()``.
Fixes #9319.

chris-morgan/rust/unreachable-macro-part-two-of-two-containing-the-destruction-of-the-unreachable-function, r=alexcrichton
This is the second of two parts of #8991, now possible as a new snapshot
has been made. (The first part implemented the unreachable!() macro; it
was #8992, 6b7b8f2682.)
``std::util::unreachable()`` is removed summarily; any code which used
it should now use the ``unreachable!()`` macro.
Closes #9312.
Closes #8991.

Previously, the lexer calling `rdr.fatal(...)` would report the span of
the last complete token, instead of a span within the erroneous token
(besides one span fixed in 1ac90bb).
This branch adds wrappers around `rdr.fatal(...)` that sets the span
explicilty, so that all fatal errors in `libsyntax/parse/lexer.rs` now
report the offending code more precisely. A number of tests try to
verify that, though the `compile-fail` testing setup can only check that
the spans are on the right lines, and the "unterminated string/block
comment" errors can't have the line marked at all, so that's incomplete.
This closes #9149.
Also, the lexer errors now report the offending code in the error message,
not just via the span, just like other errors do.

The `Drop` implementation was used to prevent `Future` from being implicitly copyable. Since `~fn`s are no longer copyable, this is no longer needed. I added a cfail test to make sure that this is actually the case.
I method-ized all of the `Future` creation methods and added a new one, `spawn_with`, which is similar to `task::spawn_with`.
I also got rid of some unused imports in tests.

It was only there to prevent Future from being copyable, but it's
noncopyable anyways since it contains a ~fn.

This renames the syntax-extension file to format from ifmt, and it also reduces
the amount of complexity inside by defining all other macros in terms of
format_args!
|
|
Closes #5794
|
|
|
|
The purpose of this macro is to further reduce the number of allocations which
occur when dealing with formatting strings. This macro will perform all of the
static analysis necessary to validate that a format string is safe, and then it
will wrap up the "format string" into an opaque struct which can then be passed
around.
Two safe functions are added (write/format) which take this opaque argument
structure, unwrap it, and then call the unsafe version of write/format (in an
unsafe block). Other than these two functions, it is not intended for anyone to
ever look inside this opaque struct.
The macro looks a bit odd, but mostly because of rvalue lifetimes this is the
only way for it to be safe that I know of.
Example use-cases of this are:
* third-party libraries can use the default formatting syntax without any
forced allocations
* the fail!() macro can avoid allocating the format string
* the logging macros can avoid allocation any strings

This removes another large chunk of this odd 'clownshoes' identifier showing up
in symbol names. These all originated from external crates because the encoded
items were encoded independently of the paths calculated in ast_map. The
encoding of these paths now uses the helper function in ast_map to calculate the
"pretty name" for an impl block.
Unfortunately there is still no information about generics in the symbol name,
but it's certainly vastly better than before
hash::__extensions__::write::_version::v0.8
becomes
hash::Writer$SipState::write::hversion::v0.8
This also fixes bugs in which lots of methods would show up as `meth_XXX`, they
now only show up as `meth` and throw some extra characters onto the version
string.
|
|
These commits fix bugs related to identically named statics in functions of implementations in various situations. The commit messages have most of the information about what bugs are being fixed and why.
As a bonus, while I was messing around with name mangling, I improved the backtraces we'll get in gdb by removing `__extensions__` for the trait/type being implemented and by adding the method name as well. Yay!
|
|
Remove __extensions__ from method symbols as well as the meth_XXX. The XXX is
now used to append a few characters at the end of the name of the symbol.
Closes #6602

Otherwise extra stuff after a lone '}' character is simply ignored, which is
very bad.
Closes #8938

This is currently unsound since `bool` is represented as `i8`. It will
become sound when `bool` is stored as `i8` but always used as `i1`.
However, the current behaviour will always be identical to `x & 1 != 0`,
so there's no need for it. It's also surprising, since `x != 0` is the
expected behaviour.

Current access methods are nestable and unsafe. This patch renames
current methods implementation - prepends unsafe_ - and implements 2 new
methods that are both safe and un-nestable.
Fixes #7473

There are 6 new compiler recognised attributes: deprecated, experimental,
unstable, stable, frozen, locked (these levels are taken directly from
Node's "stability index"[1]). These indicate the stability of the
item to which they are attached; e.g. `#[deprecated] fn foo() { .. }`
says that `foo` is deprecated.
This comes with 3 lints for the first 3 levels (with matching names) that
will detect the use of items marked with them (the `unstable` lint
includes items with no stability attribute). The attributes can be given
a short text note that will be displayed by the lint. An example:
#[warn(unstable)]; // `allow` by default
#[deprecated="use `bar`"]
fn foo() { }
#[stable]
fn bar() { }
fn baz() { }
fn main() {
foo(); // "warning: use of deprecated item: use `bar`"
bar(); // all fine
baz(); // "warning: use of unmarked item"
}
The lints currently only check the "edges" of the AST: i.e. functions,
methods[2], structs and enum variants. Any stability attributes on modules,
enums, traits and impls are not checked.
[1]: http://nodejs.org/api/documentation.html
[2]: the method check is currently incorrect and doesn't work.

I've added a test for the second example mentioned in #5239. The first example does not compile with a reasonable error message. Should I add a compile-fail test for that example as well?
/rust/src/test/run-pass/issue-5239.rs:15:45: 15:51 error: binary operation + cannot be applied to type `&int`
rust/src/test/run-pass/issue-5239.rs:15 let _f = |ref x: int| { x += 1};

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.

They are still present as part of the borrow check.

nikomatsakis/rust/issue-8625-assign-to-andmut-in-borrowed-loc-2, r=pcwalton
Fixes for #8625 to prevent assigning to `&mut` in borrowed or aliasable locations. The old code was insufficient in that it failed to catch bizarre cases like `& &mut &mut`.

This is a pull request for #2275
I've created a small python script to generate test files for a list of keywords (as break do else enum extern false fn for if impl let loop match mod mut priv pub ref return self static struct super true trait type unsafe use while), but I'm not really sure where to put it. I've added the created files as well.
I did not use
fn main() {
let $KW = "foo"; //~ error
println($KW); //~ error
}
as template, because for return, self, ref, loop, mut and break this does not raise an error in the ```println``` line, only in the ```let``` line.
