近期node社区一直在在热火朝天的完善libuv中.
新功能开发方面的似乎变动不大.
从目前的使用来看,在osx下稳定性还不错.可用度也很高
窃以为, 已经可以作为开发环境来了.
btw.前几天出了个missing headers files的编译问题

这里把v0.5引入的新功能做了各简单的汇总.

Buffer

二进制数值读写

• buffer.readUInt8(offset, endian)


• buffer.readUInt16(offset, endian)


• buffer.readUInt32(offset, endian)


• buffer.readInt8(offset, endian)


• buffer.readInt16(offset, endian)


• buffer.readInt32(offset, endian)


• buffer.readFloat(offset, endian)


• buffer.readDouble(offset, endian)


• buffer.writeUInt8(value, offset, endian)


• buffer.writeUInt16(value, offset, endian)


• buffer.writeUInt32(value, offset, endian)


• buffer.writeInt8(value, offset, endian)


• buffer.writeInt16(value, offset, endian)


• buffer.writeInt32(value, offset, endian)


• buffer.writeFloat(value, offset, endian)


• buffer.writeDouble(value, offset, endian)

buffer填充

• buffer.fill(value, offset=0, length=-1)

Child Process

child_process.fork

主进程与子进程简单通信

// master.js

var cp = require(‘child_process’);

var n = cp.fork(__dirname + ‘/child.js’);

n.on('message’, function(m) {

  console.log('PARENT got message:’, m);

});

n.send({ hello: ‘world’ });



// child.js

process.on('message’, function(m) {

  console.log('CHILD got message:’, m);

});

process.send({ foo: ‘bar’ });

File System

chown支持

• fs.chown(path, mode, [callback])


• fs.chownSync(path, mode)


• fs.fchown(path, mode, [callback])


• fs.fchownSync(path, mode)


• fs.lchown(path, mode, [callback])


• fs.lchownSync(path, mode)

timestamp修改

• fs.utimes(path, atime, mtime, callback)


• fs.utimesSync(path, atime, mtime)


• fs.futimes(path, atime, mtime, callback)


• fs.futimesSync(path, atime, mtime)

fsync支持

• fs.fsync(fd, callback)


• fs.fsyncSync(fd)

file.writeStream

file.bytesWritten

Http

http.request与http.getAgent支持unix domain socket

OS

• os.platform()


• os.arch()


• os.release()


• os.getNetworkInterfaces()

process

• process.arch


• process.uptime()

其他

新增对module cache的访问 require.cache

新增对主module的访问 require.main

新增异步模快定义的支持

define(function (require, exports, module) {

   var PI = Math.PI;

    exports.area = function ® {

       return PI * r * r;

   };

    exports.circumference = function ® {

       return 2 * PI * r;

   };

});
