-- Hello and welcome to the 12th issue of *This Week in Rust*. Sorry for the brevity, though most weeks are probably going to be like this, as I've started uni and have much less free time than in the summer. <!-- more --> # What's cooking in master? A whopping 71 pull requests were merged this week, and issue churn remains negative at -32. ## Breaking changes - [**`yield` is now reserved as a keyword**](https://github.com/mozilla/rust/pull/8560), with the hope of maybe using it for generators. - [The type of `extern fn foo` is now `extern "C" fn`, rather than `*u8`](https://github.com/mozilla/rust/pull/8666). - [Some free functions in `extra::json` were turned into associated functions on the Json enum](https://github.com/mozilla/rust/pull/8679). - [`XorShiftRng::new()` now uses a random seed](https://github.com/mozilla/rust/pull/8558). This is only breaking if you were depending on that constant seed, which you shouldn't have. ## Library changes - [`extra::getopts` aligns based on codepoint count and not byte count](https://github.com/mozilla/rust/pull/8710), as a step towards more correct unicode handling. - [`fprintf` has been added, as well as some `ifmt` cleanup](https://github.com/mozilla/rust/pull/8637). [The new runtime has seen a lot of optimization](https://github.com/mozilla/rust/pull/8740). - [File IO has been added to the new runtime](https://github.com/mozilla/rust/pull/8655). - [Some parsing errors related to ports have been fixed in `extra::url`](https://github.com/mozilla/rust/pull/8616). - [CharIterator has seen some optimization too, with reverse iterators being much closer in performance to forward iterators now](https://github.com/mozilla/rust/pull/8590). - [sysconf named have been added for android](https://github.com/mozilla/rust/pull/8602). - [The new runtime now has threadsafe IO](https://github.com/mozilla/rust/pull/8631). - [A callback optimization has sped up message passing benchmarks to the tune of 40%](https://github.com/mozilla/rust/pull/8566). - [jemalloc is back](https://github.com/mozilla/rust/pull/8584). ## Compiler changes - [gnueabihf actually uses hard floats now](https://github.com/mozilla/rust/pull/8736). - [Frame pointer elimination is no longer disabled](https://github.com/mozilla/rust/pull/8695). - [Some debuginfo fixes landed](https://github.com/mozilla/rust/pull/8684). Supposedly, libstd can now be compiled with `-Z debug-info`. Yay! - [Stack unwinding on 32-bit windows now works](https://github.com/mozilla/rust/pull/8596). This is a major step forward for Windows support, I'm very excited to see it land. - [A handful of default method bugs have been fixed](https://github.com/mozilla/rust/pull/8659). - [Inheriting from kinds now sorta works](https://github.com/mozilla/rust/pull/8562), you can do `trait Foo: Freeze`, for example. - [Supertrait methods can now be used from a trait object](https://github.com/mozilla/rust/pull/8519). - The rest of pnkfelix's visitor trait rewrite series landed. [2](https://github.com/mozilla/rust/pull/8539), [3](https://github.com/mozilla/rust/pull/8619), [4](https://github.com/mozilla/rust/pull/8623), and [5](https://github.com/mozilla/rust/pull/8638). - [Foreign function wrappers have been removed](https://github.com/mozilla/rust/pull/8535). - [LLVM has been updated](https://github.com/mozilla/rust/pull/8328). ## Docs etc - [A new condition tutorial has been added](https://github.com/mozilla/rust/pull/8563). - [Some docs for trait bounds have been added](https://github.com/mozilla/rust/pull/8725). # Meeting The [Tuesday meeting](https://github.com/mozilla/rust/wiki/Meeting-weekly-2013-08-20) discussed cycle time and how to fix it. # Projects and discussion - [gl-rs](https://github.com/bjz/gl-rs) is now ready for use, since the foreign function wrappers have been removed! - [msgpack-rust](https://github.com/omasanori/msgpack-rust) has been created. It ties into `extra::serialize`. - [A template for Arduino Due projects](https://github.com/jensnockert/dueboot). - [Parallel cross-language level generation benchmarks](http://www.reddit.com/r/rust/comments/1kxz7y/benchmarks_round_two_parallel_go_rust_d_scala_and/). - [A Week with Rust](http://www.reddit.com/r/rust/comments/1ktjrw/a_week_with_mozillas_rust/). _______________________________________________ Rust-dev mailing list [email protected] https://mail.mozilla.org/listinfo/rust-dev
