And before collect_failure. These are both running user dtors and need to be handled
in the task try/catch block and before the final task cleanup code.
A test case was also created for this situation to prevent the problem
occuring again.
A similar problem was also fixed for the symbol method.
There was some minor code cleanup.
I am unsatisfied with using /dev/null as an invalid dynamic library. It is not cross platform.
rvalues aren't going to be used anywhere but as the argument, so
there's no point in copying them. LLVM used to eliminate the copy
later, but why bother emitting it in the first place?
The `new` constructor uses the task-local RNG to retrieve seeds for the
two key values, which requires the runtime. Exposing a constructor that
takes the keys directly allows HashMaps to be used in programs that wish
to avoid the runtime.

The method .into_owned() is meant to be used as an optimization when you
need to get a ~str from a Str, but don't want to unnecessarily copy it
if it's already a ~str.
This is meant to ease functions that look like
fn foo<S: Str>(strs: &[S])
Previously they could work with the strings as slices using .as_slice(),
but producing ~str required copying the string, even if the vector
turned out be a &[~str] already.
I don't have any concrete uses for this yet, since the one conversion I've done to `&[S]` so far (see PR #8203) didn't actually need owned strings. But having this here may make using `Str` more attractive.
It also may be worth adding an `into_managed()` function, but that one is less obviously useful than `into_owned()`.
RWArc had a clone() method, but it was part of impl RWArc instead of
an implementation of Clone.
Stick with the explicit implementation instead of deriving Clone so we
can have a docstring.
Fixes#8052.
I suspect that this is a race between process exit and the termination of
worker threads used by libuv (if I sleep before exit it doesn't leak). This
isn't going to cause any real problems but should probably be fixed at
some point.
This is preparation for removing `@fn`.
This does *not* use default methods yet, because I don't know
whether they work. If they do, a forthcoming PR will use them.
This also changes the precedence of `as`.
Sigil highlighting isn't perfect (especially how it handles ``&``) but
after having used it for a week I feel it to be considerably nicer than
nothing. As usual, if you don't like it, you can turn it off easily by
overriding the default highlighting.
Generics are not handled specially; this means that for something like
``S<T>``, the ``<`` and ``>`` are highlighted as operators. For myself,
I like this, and there is no way to make it properly context aware
without expanding the syntax matching enormously.
Also, special characters are highlighted properly in strings/chars, e.g.
``"\x00"`` or ``'\Ufedcba98'`` appropriately.
OS X defaults the ulimit for open files to 256 for programs launched
from the Terminal (GUI apps get a higher default). Unfortunately this is
too low for the rt tests, which deliberately overcommit and create a lot
of threads (which means a lot of schedulers, and each scheduler needs at
least 2 fds).
By calling sysctl() and setrlimit() we can bump the fd limit up to the
maximum allowed (on stock OS X it's 10240).
Fixes#7772.
Added functions to cryptoutil.rs that perform an addition after shifting
the 2nd parameter by a specified constant. These function fail!() if integer
overflow will result. Updated the Sha2 implementation to use these functions.
Create a helper function in cryptoutil.rs which feeds 1,000,000 'a's into
a Digest with varying input sizes and then checks the result. This is
essentially the same as one of Sha1's existing tests, so, that test was
re-implemented using this method. New tests were added using this method for
Sha512 and Sha256.
The Sha2 compression functions were re-written to execute the message
scheduling calculations in the same loop as the rest of the compression
function. The compiler is able to generate much better code. Additionally,
innermost part of the compression functions were turned into macros to
reduce code duplicate and to make the functions more concise.
There are 2 main pieces of functionality in cryptoutil.rs:
* A set of unsafe function for efficiently reading and writing u32 and u64
values. All of these functions are fairly easy to audit to confirm that
they do what they are supposed to.
* A FixedBuffer struct. This struct keeps track of input data until there
is enough of it to execute the a function on it which expects a fixed
block of data.
The Sha2 module was rewritten to take advantage of the new functions in
cryptoutil as well as FixedBuffer. The result is that the duplicate code
for maintaining a buffer of input data is removed from the Sha512 and
Sha256 implementation. Additionally, the FixedBuffer code is much more
efficient than the previous code was.
The result_X() methods just calculate an output of a fixed size. They don't
really have much to do with running the actually hash algorithm until the very
last step - the output. It makes much more sense to put all this logic into
the Digest impls for each specific variation on the hash function.
The code was arranged so that the core Sha2 code came first, and then
all of the various implementation of Digest followed along later. The
problem is that the Sha512 compression function code is far away from
the Sha512 Digest implementation, so, if you are trying to read over
the code, you need to scroll all around the file for no good reason. The
code was rearranged so that all of the Sha512 code is in one place and
all of the Sha256 code is in another and so that all impls for a struct
are near the definition of that struct.
multicast functions now take IpAddr (without port), because they dont't
need port.
Uv* types renamed:
* UvIpAddr -> UvSocketAddr
* UvIpv4 -> UvIpv4SocketAddr
* UvIpv6 -> UvIpv6SocketAddr
"Socket address" is a common name for (ip-address, port) pair (e.g. in
sockaddr_in struct).
