Subteam report: libs 2016-03-11

Highlights

This week was focused on selecting APIs for stabilization/deprecation in the Rust 1.9 release cycle. These are the APIs entering their six week final comment period:

• panic::recover - stabilize
• std::raw - deprecate the slice-related bits
• the str_char feature - mixture of stabilization/deprecation
• ptr::as_ref - stabilization pending a good name
• char encoding methods - stabilization with a tweaked API
• ascii into methods - needs discussion
• CommandExt::session_leader - deprecate
• utf-16 decoding iterators - stabilize
• set recovery methods - stabilize
• OsString capacity/length methods - stabilize
• pthread_t from JoinHandle - stabilize (but some open questions)
• the #[deprecated] attribute - stabilize
• OpenOptions::create_new - stabilize (but some open questions)
• panic::propagate - stabilize
• getting hashers from HashMap and HashSet - stabilize
• CommandExt::{exec, before_exec} - stabilize, maybe before_exec too
• File::try_clone - stabilize
• SocketAddr::set_* methods - stabilize
• copy_from_slice - stabilize
• ptr::{read,write}_volatile - stabilize pending an LLVM assertion fix
