2015-03-21std: Tweak rt::at_exit behaviorAlex Crichton-8/+16
There have been some recent panics on the bots and this commit is an attempt to appease them. Previously it was considered invalid to run `rt::at_exit` after the handlers had already started running. Due to the multithreaded nature of applications, however, it is not always possible to guarantee this. For example [this program][ex] will show off the abort. [ex]: https://gist.github.com/alexcrichton/56300b87af6fa554e52d The semantics of the `rt::at_exit` function have been modified as such: * It is now legal to call `rt::at_exit` at any time. The return value now indicates whether the closure was successfully registered or not. Callers must now decide what to do with this information. * The `rt::at_exit` handlers will now be run for a fixed number of iterations. Common cases (such as the example shown) may end up registering a new handler while others are running perhaps once or twice, so this common condition is covered by re-running the handlers a fixed number of times, after which new registrations are forbidden. Some usage of `rt::at_exit` was updated to handle these new semantics, but deprecated or unstable libraries calling `rt::at_exit` were not updated.
2015-02-28std: Implement stdio for `std::io`Alex Crichton-0/+59
This is an implementation of RFC 899 and adds stdio functionality to the new `std::io` module. Details of the API can be found on the RFC, but from a high level: * `io::{stdin, stdout, stderr}` constructors are now available. There are also `*_raw` variants for unbuffered and unlocked access. * All handles are globally shared (excluding raw variants). * The stderr handle is no longer buffered. * All handles can be explicitly locked (excluding the raw variants). The `print!` and `println!` machinery has not yet been hooked up to these streams just yet. The `std::fmt::output` module has also not yet been implemented as part of this commit.
