Subject: ITP: async -- a library for OCaml asynchronous programming Package: wnpp Owner: Lifeng Sun <lifongsun@gmail.com> Severity: wishlist X-Debbugs-CC: debian-ocaml-maint@lists.debian.org * Package name : async Version : 109.35.00 Upstream Author : Jane Street Capital LLC <opensource@janestreet.com> * URL : https://github.com/janestreet/async * License : Apache-2.0 Programming Lang: OCaml Description : a library for OCaml asynchronous programming Async uses non-preemptive user-level threads and first-class blocking operations with blocking expressed in the type system to implement asynchronous programming. The benefits of the approach are: * Non-preemptive threading is simpler to reason about than pre-emptive threading. For the bulk of one's program, one doesn't have to think about race conditions, mutexes, etc. One can also use existing non-thread-safe code without worries. * User level threads are much cheaper than threads provided by the operating system, both in creation and context switching. * We control the scheduler for our threads, which makes it possible for us to do a better job for the application at hand. * Writing low latency applications is easier -- it's harder to have an application block indefinitely by mistake. --
