This appears to be causing the BSD bots to lock up when looking at the core
dumps I've managed to get. Dropping the `FileDesc` structure triggers the `Arc`
it's contained in to get cleaned up, invoking free(). This instead just closes
the file descriptor (the arc itself is never cleaned up).
I'm still not entirely sure why this is a problem because the pthreads runtime
should register hooks for fork() to prevent this sort of deadlock, but perhaps
that's only done on linux?
... also don't read the whole directory if the glob for that path
component doesn't contain any metacharacters.
Patterns like `../*.jpg` will work now, and `.*` will match both `.` and
`..` to be consistent with shell expansion.
As before: Just `*` still won't match `.` and `..`, while it will still
match dotfiles like `.git` by default.
Add requirements of TotalEq and TotalOrd
Clarify that TotalEq needs an underlying equivalence relation and that TotalOrd
needs a total ordering and specifically named the required (and sufficient)
attributes.
This test relies on the parent to be descheduled before the child sends its
data. This has proved to be unreliable on libnative on the bots. It's a fairly
trivial test regardless, so ignoring it for now won't lose much.
`Reader`, `Writer`, `MemReader`, `MemWriter`, and `MultiWriter` now work with `Vec<u8>` instead of `~[u8]`. This does introduce some extra copies since `from_utf8_owned` isn't usable anymore, but I think that can't be helped until `~str`'s representation changes.
In the error message for when a private field is used, include the name of the struct, or if it's a struct-like enum variant, the names of the variant and the enum.
This fixes#13341.
Rust currently defaults to `RelocPIC` regardless. This patch adds a new
codegen option that allows choosing different relocation-model. The
available models are:
- default (Use the target-specific default model)
- static
- pic
- no-pic

In summary these are some example transitions this change makes:
'a || => ||: 'a
proc:Send() => proc():Send
The intended syntax for closures is to put the lifetime bound not at the front
but rather in the list of bounds. Currently there is no official support in the
AST for bounds that are not 'static, so this case is currently specially handled
in the parser to desugar to what the AST is expecting. Additionally, this moves
the bounds on procedures to the correct position, which is after the argument
list.
The current grammar for closures and procedures is:
procedure := 'proc' [ '<' lifetime-list '>' ] '(' arg-list ')'
[ ':' bound-list ] [ '->' type ]
closure := [ 'unsafe' ] ['<' lifetime-list '>' ] '|' arg-list '|'
[ ':' bound-list ] [ '->' type ]
lifetime-list := lifetime | lifetime ',' lifetime-list
arg-list := ident ':' type | ident ':' type ',' arg-list
bound-list := bound | bound '+' bound-list
bound := path | lifetime
This does not currently handle the << ambiguity in `Option<<'a>||>`, I am
deferring that to a later patch. Additionally, this removes the support for the
obsolete syntaxes of ~fn and &fn.

First, documented the existing `CTEST_DISABLE_$(TEST_GROUP)` pattern
for conditionally disabling tests based on missing host features.
Added variant of above, `CTEST_DISABLE_NONSELFHOST_$(TEST_GROUP)`,
which is only queried in contexts where the target is not on the
CFG_HOST list (which I interpret as the list of targets that our host
can compatibly emulate; e.g. the example that i686 and x86_64 can in
theory run each others' tests).
Driveby fix: Remove redundant copy of
check-stage$(1)-T-$(2)-H-$(3)-$(4)-exec dependency declaration.
Fix an unnecessary use of `cast::transmute`
Wherever possible, more specialized variants of said functions should be used,
such as in this case `cast::transmute_mmut_unsafe`.
This can be a frustrating error message, ideally we should print the signature mismatch, but hinting that it's a trait incompatibility helps tracking root cause. Also beefed up the testcases for this.
Ideally we would print the signature mismatch in the error helper?
