Also cleanup the treatment of mutability in mem_categorization, which still
included the concept of interior mutability. At some point, we should
refactor the types to exclude the possibility of interior mutability rather
than just ignoring the mutability value in those cases.
to favor inherent methods over extension methods.
The reason to favor inherent methods is that otherwise an impl
like
impl Foo for @Foo { fn method(&self) { self.method() } }
causes infinite recursion. The current change to favor inherent methods is
rather hacky; the method resolution code is in need of a refactoring.
what amount a T* pointer must be adjusted to reach the contents
of the box. For `~T` types, this requires knowing the type `T`,
which is not known in the case of objects.
This PR does a bunch of cleaning up of various APIs. The major one is that it merges `Iterator` and `IteratorUtil`, and renames functions like `transform` into `map`. I also merged `DoubleEndedIterator` and `DoubleEndedIteratorUtil`, as well as I renamed various .consume* functions to .move_iter(). This helps to implement part of #7887.
I'm a bit disappointed that I couldn't figure out how to factor out more of the code implementing `extra::sync` but I feel this is an okay start. Also I added some documentation explaining that `WaitQueue` isn't thread safe, and needs an exclusive lock.

When there is only a single store to the ret slot that dominates the
load that gets the value for the "ret" instruction, we can elide the
ret slot and directly return the operand of the dominating store
instruction. This is the same thing that clang does, except for a
special case that doesn't seem to affect us.
Fixes#8238

This PR fixes#7235 and #3371, which removes trailing nulls from `str` types. Instead, it replaces the creation of c strings with a new type, `std::c_str::CString`, which wraps a malloced byte array, and respects:
* No interior nulls
* Ends with a trailing null
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).
Get rid of special cases for names beginning with "rust-" or
containing hyphens, and just store a Path in a package ID. The Rust-identifier
for the crate is none of rustpkg's business.
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
Mostly optimizing TLS accesses to bring local heap allocation performance
closer to that of oldsched. It's not completely at parity but removing the
branches involved in supporting oldsched and optimizing pthread_get/setspecific
to instead use our dedicated TCB slot will probably make up for it.
