新闻 Erlang/OTP 19.0.rc1 发布，动态类型编程语言 下载

Erlang/OTP 19.0.rc1 发布了。

Erlang是一个结构化，动态类型编程语言，内建并行计算支持。最初是由爱立信专门为通信应用设计的，比如控制交换机或者变换协议等，因此非常适 合于构建分布式，实时软并行计算系统。

主要更新内容：

• 
  compiler, stdlib:
  
  
  • 
    New preprocessor macros ?FUNCTION_NAME, ?FUNCTION_ARITY
    
    
  • 
    New preprocessor directives -error(Term) and -warning(Term) to cause a compilation error or warning, respectively.
    
• 
  gen_statem a new state machine behavior
  
  
• 
  mnesia_ext: plugin of external storage solutions to mnesia
  
  
• 
  crypto: uses EVP interface in OpenSSL resulting in generally better performance and support for HW acceleration
  
  
• 
  ssh: performance improvements, uses the new gen_statem behavior
  
  
• 
  dialyzer: the support for maps is very much extended both the type specification syntax and the type analysis.
  
  
• 
  erts:
  
  
  • 
    erlangpen_port(spawn, ...) 3-5 times faster
    
    
  • 
    tracing, extensive improvements (scalability, speed, match specifications on send/receive, support for lttng, ...)
    
    
  • 
    dirty schedulers improved
    
    
  • 
    per process configurable handling of message_queue
    
    
  • 
    fast loading of multiple modules
    
    
  • 
    max_heap_size process flag
    
    
  • 
    and much more ....
