-- Hello and welcome to the sixth issue of *This Week in Rust*, a weekly overview of Rust and its community. <!-- more --> # What's cooking on master? Issue churn this week was -17! A total of 63 PRs were merged this week, twice as many as last week. Not bad! ## Breaking changes - The [task local storage (TLS) API](https://github.com/mozilla/rust/pull/7677) was cleaned up (there's still [one PR](https://github.com/mozilla/rust/pull/7751) in the queue that finishes it up). - [DList was modernized](https://github.com/mozilla/rust/pull/7652). - [`extra::json` now uses `Iterator<char>` rather than a `@Reader`](https://github.com/mozilla/rust/pull/7704) - [Various free-standing functions in f32 etc were removed](https://github.com/mozilla/rust/pull/7117) - [ref bindings in irrefutable patterns has been tightened up](https://github.com/mozilla/rust/pull/7262). This potentially fixes *and breaks* code. It's breaking because the compiler now rejects incorrect programs that it did not before. - [str no longer encodes invalid utf-8](https://github.com/mozilla/rust/pull/7612). - [`extra::rope` was removed](https://github.com/mozilla/rust/pull/7629) - [`extra::net_ip` and so on were removed](https://github.com/mozilla/rust/pull/7594). They were redundant names for `extra::net::ip` and such - [`Iterator::size_hint`'s lower bound is no longer an Option](https://github.com/mozilla/rust/pull/7570) ## Notable compiler additions, bugfixes, and cleanup - [Unnecessary basic blocks were removed](https://github.com/mozilla/rust/pull/7763). This makes for much easier to read unoptimized IR. - [Use of `*int`/`*uint` is now properly warned](https://github.com/mozilla/rust/pull/7734) in FFI functions. - [More default method fixes](https://github.com/mozilla/rust/pull/7725). - A [needless copy](https://github.com/mozilla/rust/pull/7717) was removed from immediate values (I'm pretty sure LLVM optimized it away when optimizations were on, not positive). - A [lint for overqualified names](https://github.com/mozilla/rust/pull/7706) was added. - [SIMD arithmetic](https://github.com/mozilla/rust/pull/7705) was implemented. - A [graph abstraction and CFG](https://github.com/mozilla/rust/pull/7688) was introduced, to unify how the various pieces of the compiler use graphs. - [The maximum lifetime of stack closures](https://github.com/mozilla/rust/pull/7455) is now constrained. Not quite sure what that means, but it fixes a segfault. - [repr doesn't infinite loop](https://github.com/mozilla/rust/pull/7683) on zero-sized structs (ie, unit structs). - [Type parameter pretty printing](https://github.com/mozilla/rust/pull/7698) was fixed, it now prints the type name rather than `'a` and `'b` and soforth. - [`mut` in default method arguments is now allowed](https://github.com/mozilla/rust/pull/7631). - [IR for calls with immediate return values](https://github.com/mozilla/rust/pull/7645) was improved. - [Exchange allocation headers (ie, the headers on `~T`) were removed](https://github.com/mozilla/rust/pull/7605). This was a heroic effort by strcat and Luqman. - [`-Z trans-stats` now reports perf-function statistics](https://github.com/mozilla/rust/pull/7456) - [Scopes were decoupled from LLVM basic blocks](https://github.com/mozilla/rust/pull/7636), improving unoptimized builds, and allowing more things in optimized builds to be inlined. - [An infinite loop when recursively including modules](https://github.com/mozilla/rust/pull/7585) was fixed. - An [ICE involving struct-like enum variants](https://github.com/mozilla/rust/pull/7557) was fixed. - The buildsystem [cleans up old libraries](https://github.com/mozilla/rust/pull/7637) when it needs to. - [A bunch of managed boxes](https://github.com/mozilla/rust/pull/7615) were removed from the AST. ## Notable library additions, bugfixes, and cleanup - [`print!` and `println!` macros](https://github.com/mozilla/rust/pull/7775) were added (though [#7779](https://github.com/mozilla/rust/issues/7779) renames them). - [Ord now uses default methods](https://github.com/mozilla/rust/pull/7765), allowing you to get default implementations for everything but `lt`. - [`extra::Bitv` now takes `&[bool]` rather than `~[uint]`](https://github.com/mozilla/rust/pull/7730). - [x64 now uses large stacks (4 MiB) by default](https://github.com/mozilla/rust/pull/7728). - [`is_utf8` is now 22% faster](https://github.com/mozilla/rust/pull/7696) - [Metrics reporting and ratcheting](https://github.com/mozilla/rust/pull/7623) was added to the test harness. - A [DoubleEndedIterator](https://github.com/mozilla/rust/pull/7707) was added. - A [`mut_split` method was added](https://github.com/mozilla/rust/pull/7691) to partition a `&mut [T]` into two pieces. - We [now have pointer arithmetic](https://github.com/mozilla/rust/pull/7631). - A [month's work of runtime work](https://github.com/mozilla/rust/pull/7265) landed. - [A safe, cross-platform `mmap` wrapper](https://github.com/mozilla/rust/pull/7528) was added. - [SmallIntMap and SmallIntSet have external iterators](https://github.com/mozilla/rust/pull/7614). - [JSON parsing got 93% faster](https://github.com/mozilla/rust/pull/7608) - [Deque](https://github.com/mozilla/rust/pull/7562) got a good cleanup and speedup. - [vec now implements `pop_opt` and `shift_opt` methods](https://github.com/mozilla/rust/pull/7602). - A [`peek_` adaptor](https://github.com/mozilla/rust/pull/7604) was added, which calls a closure on ever item before returning it. Mostly useful for debugging your iterators. ## Documentation etc - [vim](https://github.com/mozilla/rust/pull/7742) [improvements](https://github.com/mozilla/rust/pull/7665) landed. - [`po4a` support for translation](https://github.com/mozilla/rust/pull/7641) was added. - [`libc::c_void` is better documented](https://github.com/mozilla/rust/pull/7690). - [Man pages](https://github.com/mozilla/rust/pull/7632) for all the tools are now included. - The [iterator tutorial](https://github.com/mozilla/rust/pull/7736) was extended. # Meetings The [Tuesday meeting](https://github.com/mozilla/rust/wiki/Meeting-weekly-2013-07-09) was all about split stacks and FFI. It's complex and above my ability to summarize, but from what I can tell no real consensus was made. But, it's the best enumeration of all the various issues surrounding split stacks that I've seen. # Discussion + Blog posts >From now on I'm going to just link to the reddit thread if there is one, as it often has additional comments or insights. - [A simple, self-contained example of using a shared library](https://gist.github.com/jmptable/5980297) - [Experimental Actor Library (reddit)](http://www.reddit.com/r/rust/comments/1i3c15/experimental_actor_library_in_rust/) - [Herb Sutter describes Rust (reddit)](http://www.reddit.com/r/rust/comments/1i30sw/herb_sutter_describes_rust_c_questions_and/) - [Philosophy and "for" loops (reddit)](http://www.reddit.com/r/rust/comments/1i2y9e/philosophy_and_for_loops_more_from_go_and_rust/) - [Reddit thread about the weekly meeting](http://www.reddit.com/r/rust/comments/1hy6l9/meetingweekly20130709_split_stacks_ffi/) - [BZIP2 bindings (reddit)](http://www.reddit.com/r/rust/comments/1hxp2s/little_bzip2_binding_library_as_well_as_a_bigger/) - [Proposal for an additional use case of the "in" keyword besides for loops (reddit)](http://www.reddit.com/r/rust/comments/1hsqf5/proposal_for_an_additional_use_case_of_the_in/) - [Technical Q&A on Servo (reddit)](http://www.reddit.com/r/rust/comments/1i6ykh/technical_qa_on_servo/) _______________________________________________ Rust-dev mailing list [email protected] https://mail.mozilla.org/listinfo/rust-dev
